Figure 1 shows a one embodiment of the present invention example also shown in drawing a packet according to eMBB packet URLLC coexist in one example and, according to the receiving terminal know whether terminal capability shown in Figure 2 eMBB URLLC related information are disclosed.

Low reliability and delay is checked whether the number not sensitive number 1 system service transmitting automatically change [...] number 1, number 2 at a first low delay (latency) number corresponding to the number 2 service system requiring [...] should transmit the state of the packet, base station provides high reliability required number 2 is checked whether service rejection forces to be dynamically allocates the resources. For example, mobile service said number 1 may be ultra-wideband communication service (eMBB: enhanced mobile broad band), eMBB system includes a system for number 1, number 2 service/ultra high reliability and low delay communication service (URLLC: ultra-a reliable and low latency communication), the system can be URLLC system number 2. Hereinafter, descriptions and to receive, for example eMBB URLLC service supported service mobile communication system illustrating the substrate. However, the which are not limited to, heterogeneous services is such that if the present invention refers to force ball number can be. For example, URLLC, eMBB, large-scale inter-device communication service (mMTC: massive machine type communication), next generation broadcasting service (eMBMS: evolved multimedia broadcast/multicast Service) and the like can be force even supported mobile communication system.

In the case of URLLC, other services contrast ultra high reliability (for example, packet error rate about 10^-5 ) And a low delay (latency) (for example, about 0. 5Msec) C. satisfying conditions. A gaseous also illustrated as shown with the base station 1, eMBB packet (110) automatically change transmitting, URLLC packet (120) to the state of the transmitting, corresponding resources eMBB packet (110) instead URLLC packet (120) be assigned to launching the application.

And, transmission time interval (TTI: transmission time interval) eMBB eMBB system includes downlink network environment (130) through the scheduling can be based. And, URLLC system includes a shorter TTI (140) through the scheduling can be considering as a reference scenario. The, eMBB of TTI (130) a eMBB TTI, a TTI (long TTI), general TTI (normal TTI), or the like can be referred to as number 1 TTI, the terms for the received eMBB irrespective the TTI can be defines. And, URLLC of TTI (140) a URLLC TTI, short TTI (short TTI), or the like can be referred to as number 2 TTI, the terms for the received URLLC irrespective the TTI can be defines. On the other hand, in Figure 1 is eMBB TTI (130) than URLLC TTI (140) but is shorter in the take-off illustrated, but not limited to and, eMBB TTI (130) than URLLC TTI (140) is longer or eMBB TTI (130) on URLLC TTI (140) can have the same. Only, descriptions for facilitating the, eMBB TTI (130) than URLLC TTI (140) like illustratively is shorter for illustrating each other. On the other hand, receives ball number eMBB service, eMBB packet (110) capable of receiving or receiving terminal, the terminal for facilitating descriptions, eMBB terminal, such as a reception terminal eMBB can be referred.

In this case the base station service eMBB (110) automatically change URLLC transmitting packet (120) to the state of the transmitting, a corresponding resource (resource) eMBB packet (110) instead URLLC packet (120) be assigned to launching the application. In this case, eMBB packet (110) should transmit the corresponding source data symbols such as perforated (puncturing or removing) both under other.

When applying such operating, a signal eMBB number (115) is transmitted after URLLC packet (120) can be resource allocation scheduling is performed, base station a signal eMBB number (115) to URLLC packet (120) presence or absence of and related information is included transmitting cannot ensure. The, eMBB receiving terminal, i.e. eMBB packet terminal is capable of receiving a signal eMBB number (115) URLLC cannot subjected to ball number related information.

The, eMBB packet (110) is URLLC packet (120) can be generated by interference. The URLLC packet (120) interference generated by the hereinafter, descriptions for facilitating the URLLC interference, URLLC interference signal, the effects of interference signal, like the effects of interference signal URLLC into a slot, said URLLC interfering signal to interference signal URLLC information related information, interference signal information, referred to as diffuse to the effects of interference information.

In this case, its resources in the reception terminal eMBB URLLC packet (120) information to know if it exists, eMBB packet (110) receiving performance of auditory canal 2 illustrated as shown with serious degradable disclosed.

In addition, Figure 2 shows a eMBB also receiving related information when receiving a terminal URLLC techniques not accounted for, when the packet is constructed eMBB URLLC transmitted signals to at or very large negative can cause performance deterioration.

The reference 2 also, whether eMBB receiving terminal allocated to the resource region in some case whose puncturing, eMBB receiving terminal allocated to the resource region 210 and 220 respectively when puncturing in some status information shown in the nanometer range. The, eMBB receiving terminal allocated to the resource region when puncturing in some know whether, terminal to a receiving terminal according eMBB URLLC data makes its data cannot be decoded data by the signal to noise ratio (SNR: signal to noise ratio) increases block error rate (BLER: block error rate) are substantially reduced can not confirm it.

While, when the status information resource region eMBB puncturing in some change in the receiving terminal, the terminal can verify reduced BLER overlapped with the SNR value. The, whether resource region in some change in the receiving terminal eMBB compared with whose puncturing, puncturing in some change in the resource region when terminal status information is also used for error can be.

Chamber to number, experiment environment of Figure 2 of a transmitted signal is not only 10% hereinafter contrast degree URLLC eMBB transmitted signals. The performance deterioration of the receiving terminal URLLC eMBB its signal and this is taken as the system and the number of signal decoding channel's oldest.

Thus, if the use of the measured data resources if it eMBB URLLC receiving terminal, eMBB receiving performance can be significantly improved by selecting also by 2. For this reason, presence or absence of the resource utilized by the receiving terminal includes its own resources in eMBB URLLC know however, if subjected to ball number corresponding information is present operating procedure according.

In this case, the reception terminal eMBB URLLC packet (120) interference generated by interfering signal to information whose state, cyclic redundancy check (CRC: cyclical redundancy check) and the currently received signal channel decoding can be performed. And, when the CRC failure (fail) occurs by sending a NACK signal to the base station receiving terminal eMBB hybrid automatic repeat request (HARQ: hybrid automatic repeat request) can be formed by applying method.

And, transmitter, i.e. the base station receiver, i.e. eMBB receiving terminal data through the NACK signal, the transmitted signal is performed prior to the next scheduling point thereof can re-send. , the base station can re-transmit the same signal to a receiving terminal through which the transmitted information presents eMBB. The embodiment or example, the base station receiving terminal information presents another version of the transmitted signal is eMBB parity bits (parity bits) may be transmitting, said method or a combination of two new redundancy version (redundancy version) to send US disapproval. Accordingly, the system performs a base station eMBB backtransmission signal receiving terminal receives, after combining the received signal with a previous decoding channel can be performing.

Generally, receiver (i.e., eMBB reception terminal) is the received signal bit (bit) similarity ratio (LLR: log-a likelihood ratio) value calculated log unit, channel decoder input of same into 2000 KIPO. If, CRC fail because of the effects of previous channel received signal is applied, a received signal is not detected outputs corresponding LLR what is equal to having a value near 0.

The temperature detector, eMBB packet (110) to URLLC packet (120) receiving terminal eMBB URLLC signal interference affecting in situations where its signal by performing CRC fail in case of channel decoding is not considered, CRC fail occurs even if the LLR value obtained with respect to the large value near 0 having tertiary disclosed. This, CRC fail occurs under the influence of a peculiar reason channel but, eMBB receiving terminal uncorrected data is displayed by the acronym receives on its signal area are disclosed. The, this received signal stored in combination with multivalent eMBB HARQ retransmission signal receiving terminal (combining) when performing channel decoding, in combination with previous received signal has not higher performance degradation rather than can be. The, environment where such situations when the HARQ transmitting unit detects the HARQ transmitting techniques be more efficient techniques.

On the other hand, according to the example embodiment for detecting the interference signal related information receiving terminal URLLC eMBB (blind detection) using the same techniques perform blind received may be disclosed. In this case, the performance of a reception terminal eMBB URLLC utilizing interference signal related information does not contrast can be significantly improved. However, eMBB performing blind detection result and if an error occurs at the receiving terminal, using the same URLLC interference signal related information such as door number appears not terminal can be. The, supported service transmitting unit detects the HARQ URLLC eMBB service system when the HARQ transmitting techniques be more efficient techniques.

In another embodiment example, downlink network environment system URLLC eMBB eMBB TTI system (130) through the scheduling can be considering as a reference scenario. In this case the base station system to the time at which the schedule URLLC eMBB scheduling system is used, to apply resources in packet URLLC eMBB receiving terminal (120) the absence or presence of channel number (115) is identified through can be.

However, said URLLC packet (120) for the probable presence of small resource block information to the receiving information because very large amount thereof be higher. The, channel number (115) to information for informing a user of said receiving terminal through applying eMBB side, channel number (115) overhead (overhead) generate door number can be significantly increased.

Thus, the base station terminal call information to an appropriate complexity blind detection (blind detection) to number cues can be channel (115) and through part number [...], corresponding information receiving terminal utilizing blind (blind) provided information related URLLC eMBB detection can be a cylindrical shape. However, terminal performing error using blind detection result if the same number appears not URLLC information terminal such as door can be. The, channel number (115) by delivering eMBB URLLC URLLC through some information could simultaneously transmitting unit detects the HARQ system supported on even in the event a more efficient technique when the HARQ transmitting technology 2000.

The, one embodiment of the present invention example according to the base station, a signal transmitted to the terminal when an NACK signal, HARQ retransmission packet transmission, URLLC signal including information about whether interference occurs by the effects of interference transmitted information launching the application disclosed. And, the terminal HARQ retransmission packet upon receipt, the effects of interference information, performing channel decoding can be received packet.

Or, according to the example embodiment URLLC eMBB signal interference by signal potentials, base station transmits NACK signal to terminal URLLC even before the information about whether the interference due to the signal generated is transmitted after a preset duration can be transmitting. And, the base station prior to receiving the NACK signal from terminal to terminal even after a preset duration eMBB signal can be transmitting retransmission packet.

According to one embodiment of the present invention shown in Figure 3 shows a flow example operation of the base station and a terminal also are disclosed.

With reference to the 3 also, according to one embodiment of the present invention example base station (310) is in terminal 350 (320) to a new signal transmission can. The, said terminal (320) can be terminal receiving the eMBB, eMBB be a receiving terminal. And, base station (310) is eMBB service URLLC service can be V, terminal (320) can be URLLC eMBB signal as well as the signal receiving function. And, the signal a new signal number 1 systems, for example eMBB signal that is disclosed. And, said number 1 number 2 signal systems in which interference occurs by signals associated with the system can be. For example, said number 2 systems signal URLLC signal that is disclosed.

Then, terminal (320) the reception step in response to said 350, 360 ACK or NACK signal in base station (310) can be sent to.

If, base station (310) in the NACK signal when an 360, base station (310) is in terminal 370 (320) to packet re-transmission can be performed. The, base station (310) when the for retransmitting packet, repeaters in step 350 that interfering influences of information about terminal (320) can be sent to.

Said effects of interference information, interference signal can be associated information. I.e., in base station 350 (310) transmits signal supplies of different systems when the signals, the effects of interference information can be information related to generation of interference. For example, the effects of interference information, base station (310) by transmitting a signal to another system in the 350 supplies the information can indicate whether interference occurs. I.e., base station (310) in the 350 number 1 number 2 system signals the information indicative of the signal system by undesirable the signals can be transmitted in packet re-transmission in step 370.

And, said terminal (320) is, but not shown, receives a retransmitted packets, the effects of interference can be perform channel decoding said information.

For this more particularly in residual, that interfering influences said base station information (310) is previously transmitted it is possible supplies of different systems including information indicate whether interference occurs can be, this identifier can be included in the form. And, said identifier identifier can be referred to as the effects of interference. For example, the effects of interference information is to be transmitted at step 350 URLLC eMBB packet by the packets the signals comprising information indicating can be undesirable, the URLLC decides whether to eliminate undesirable by the packets the signals, the effects of interference that interfering influences URLLC identifier can be included in the information. The, when the effects of interference of the signals and said URLLC URLLC packet identifier Wednesday 1, the signals and the effects of interference identifier is not URLLC Wednesday 0, or vice versa according to the disapproval.

Said terminal receives the identifier the effects of interference (320) of displaying the signals generated previously received signal into a plurality of signals can be determined. And, if the signals previously received signal generated by signal, terminal (320) is received at a retransmission signal in step 370 350 (combining) combining a received signal with not be.

On the other hand, according to the example embodiment, said identifier in addition to the effects of interference effects of interference information, supplies of different systems can be affected of interference regions further comprising information. The, said affected area interference information about the effects of interference can be in the form identifier is included in the information. And, the effects of interference can be referred to as a same identifier. The, interference case URLLC system signals, said interference area of influence identifier can be referred to as area identifiers that interfering influences URLLC. According to the example embodiment, the effects of interference information said interference information if affected area, the effects of interference that interfering influences of identifier is not included in said additional information be.

, the effects of interference identifier and interference area of influence receives the identifier terminal (320) is, previously received signal, i.e. step 350 supplies of interference during reception of different systems can be a method of selecting areas that are not affected. The retransmission signal and said selected area only perform channel decoding can be synchronized.

In addition, according to the example embodiment, base station (310) 370 supplies of different systems in the affected area of interference signal alone can be re-transmitted. In this case, the effects of interference effects of interference information said identifier, in addition to the effects of interference area identifiers, retransmission signal type for containing further information can. , the backtransmission signal type for said information, base station in step 370 (310) is affected area supplies of different systems of interference signal alone can be information as to whether or not re-transmitted. And, the backtransmission signal type for said retransmission information form type identifier the effects of interference can be included in the information. And, the backtransmission signal can be referred to as a same type identifier. According to the example embodiment, the effects of interference information said information regarding regulatory domain and retransmission signal type for affected interference information if, the effects of interference that interfering influences of identifier is not included in said additional information be.

, the effects of interference identifier, the effects of interference area identifiers, and retransmitting receives the identifier type terminal (320) is, previously received signal, i.e. 350 supplies the received signal of different systems in areas that are not affected of interference signal can be screening. And, retransmission signal said signal contact received signal selected additional parity (parity) as water can be perform channel decoding.

On the other hand, drawing base station performs (310) terminal (320) when an NACK signal from the terminal (320) the effects of interference information to the illustrated but, not limited are not correct. For example, base station (310) 350 is sent eMBB URLLC signal in case of signal interference, base station (310) terminal (320) prior to receiving a preset duration from HARQ ACK/NACK signal even after a terminal (320) to the effects of interference can be information. And, base station (310) terminal (320) prior to receiving a preset duration from HARQ ACK/NACK signal even after a terminal (320) can be transmitting eMBB to retransmission packet.

More particularly residual, base station (310) is in terminal 350 (320) eMBB URLLC eMBB signal when signal to signal the signals as undesirable terminal (320) from known even before the NACK signal thereof can. The base station (310) terminal (320) even before the eMBB signal after transmitting the NACK signal from interference impact information terminal (320) can be sent to. For example, when second eMBB TTI eMBB signal transmitted in n, n + k the effects of interference information can be transmitted through second eMBB TTI. The, said n + k eMBB TTI is precedes the second HARQ ACK/NACK according to retransmission eMBB TTI can be.

Terminal (320) the HARQ NACK signal before transmission receives information that interfering influences said signal interference by identifying eMBB URLLC signal under the influence can be.

And, base station (310) terminal (320) the effects of interference while transmitting or said information to said information after transmitting the effects of interference can be re-transmitted signal. I.e., base station (310) terminal (320) for transmitting a transmission signal material can be even before the HARQ ACK/NACK signal from. the retransmission signal interference can be affected regions eMBB signal only.

On the other hand, the effects of interference can be sent to said said channel number information is included in the terminal. For example, the effects of interference information to m (m is 1 or more exceeds a preset value) or PDCCH EPDCCH bit identifier further toward the terminal can be sent to.

Hereinafter, base station (310) and terminal (320) to heat diffuse to the specific operation.

Figure 4 shows a one embodiment of the present invention example according to eMBB packet when URLLC packet also determines, according to one example of a drawing and the effects of interference information shown and, Figure 5 of the present invention according to one embodiment example shown in the drawing and flow operation of the base station, an operation of one embodiment according to the example shown in Figure 6 of the present invention flow are disclosed.

Such as the above-described base station (310) and terminal (320) the number 1 TTI (440) system using number 1 number 2 TTI (450) using each system service number 1308. ball number 1 number 2 number 2 service. The, number 1 TTI (440) system using eMBB system into a slot number 1, number 2 TTI (450) system using URLLC system is assumed diffuse to the number 2. The, number 2 TTI (450) corresponding to the frame number (430) same switch of number 1 region (431) to number 7 region (437) is divided into diffuse to the. In Figure 4 is subframe (430) 7 is divided into regions but the illustrated, this example only and, number 1 TTI (440) and number 2 TTI (450) of the length of the, subframe (430) as well as the at least one less than 7 or 7 may be region are disclosed. The, said number 1 region (431) to number 7 region (437) (OFDM: orthogonal frequency division multiplexing) symbol (symbol) are at least 1 comprising orthogonal frequency division of can be. For example, each region can be 2 of OFDM symbols.

The, eMBB packet (410) is number 1 TTI (440) in accordance with the entire sub-frame (430; 431, 432, 433, 434, 435, 436, 437) can be transmitted over a particular frequency range. And, URLLC packet (420, 425) is number 2 TTI (450) can be scheduling according. The, base station (310) is eMBB packet (410) automatically change URLLC transmitting packet (420, 425) to the transmitting state of the, base station (310) is URLLC packet (420, 425) to allocate resources to launching the application disclosed. The, for example number 1 URLLC packet (420) is number 3 region (433) transmitted in, number 2 URLLC packet (425) is number 6 region (436) can be transmitted. And, said number 1 URLLC packet (420) and number 2 URLLC packet (425) eMBB by packet (410) interference can be disclosed. The, such as 4 and according to the example embodiment shown in number 3 region (433) eMBB in packet (410) is entirely is number 1 URLLC packet (420) suffers from significant interference by, number 6 region (436) eMBB in packet (410) some number 2 URLLC packet (425) by the signals thereof can.

While, URLLC packet (420, 425) eMBB by packet (410) without interference when, base station (310) the effects of interference in the 840 URLLC identifier (710) corresponding to a false (false) set according to (for example, the effects of interference identifier set URLLC 0) can be storing. The transmitted signal is response signal is received base station until the effects of interference identifier said URLLC (310) can be stored. And, base station (310) is eMBB signal terminal (320) can be sent to. In this case base station (310) URLLC the effects of interference area identifiers (720) is not set (i.e., said effects of interference information (700) is that interfering influences URLLC identifier (710) which can provide only included), URLLC the effects of interference area identifiers (720) the default (default) or set, or URLLC the effects of interference area identifiers (720) such as a 0000000 can be averaged.

On the other hand, according to the example embodiment in the steps of or 840 830 base station (310) terminal (320) to eMBB signal after transmitting, in base station 850 (310) is the transmitted signal is eMBB can response message.

When the transmitted signal is ACK signal is received, base station (310) in the 870 then generates a send eMBB terminal (320) can be sent to. According to the example embodiment, base station (310) terminal (320) from when an ACK signal, storing the effects of interference in step or said 830 840 URLLC identifier (710), and/or URLLC the effects of interference area identifiers (720) can be used to initiate.

While, when the transmitted signal is NACK signal is received, base station (310) in the 860 can be performing eMBB packet is transmitted. The, base station (310) is set in step or said 830 840 that interfering influences URLLC identifier (710) together with terminal re-transmit (320) can be sent to.

The, URLLC 830 in the effects of interference area identifiers (720) is set on the basis of the, base station (310) is in said URLLC 860 the effects of interference area identifiers (720) together with terminal re-transmit (320) be sent to launching the application.

Base station (310) according to the example embodiment that interfering influences said URLLC identifier (710) and/or the effects of interference URLLC identifier (720) channel number in addition to a terminal (320) can be sent to. For example, the effects of interference said URLLC identifier (710) and/or the effects of interference URLLC identifier (720) the effects of interference information including a (700) or EPDCCH PDCCH is added to that terminal (320) can be sent to. , the effects of interference URLLC identifier (710) is 1 bit may be, URLLC the effects of interference area identifiers (720) is 1 bits 2 OFDM symbol size is established 7 bits may have.

And, according to the example embodiment base station (310) terminal (320) to the effects of interference URLLC identifier (710) and/or the effects of interference URLLC identifier (720) after re-transmit signal transmitted, that interfering influences said URLLC identifier (710) and/or the effects of interference URLLC identifier (720) can be used to initiate.

Next, terminal (320) with respect to the operation of the residual 9 also refer to more specifically, terminal (320) in the 910 can be signal. The, said signal eMBB signal that is disclosed. And, according to the example embodiment, terminal (320) performs channel compensation, the received signal bit (bit) unit LLR (bit LLR) can produce.

And, in terminal 920 (320) said 910 reception unit determines whether the step is a new signal corresponding to whether or not the retransmission signal can be.

920 In judgment result, step 610 is novel reception case, terminal (320) proceeds to the step 960 can be perform channel decoding.

In judgment result while 920, a new signal when the signal is received at a step 910, terminal (320) which is a retransmission signal can be notified to a user.

And, in terminal 930 (320) the received retransmission the effects of interference can be included in the signal presence information. , the effects of interference information that interfering influences URLLC said identifier (710) can be comprising, terminal (320) is received at step 910 it is possible URLLC backtransmission signal previously received packet (420, 425) identifying by the signals can be undesirable. I.e., terminal (320) is that interfering influences URLLC identifier (710) by checking, it is possible by the signals identifying previously received output values of the URLLC can be undesirable.

If it is not the signals previously received URLLC signal when the, terminal in step 940 (320) is stored with a previously received signal with the currently received re-transmission signal be LLR and the com inning it will do.

While, it is possible at all the signals previously received URLLC signal when the decision, in terminal 950 (320) is the effects of interference can be URLLC identifying area information. I.e., terminal (320) URLLC the effects of interference area identifiers (720) can identify, contact the signal which has been subjected to interference URLLC identifying a free area, in which the selecting URLLC the signals can be. For example, terminal (320) is set to 0 said URLLC LLR region of the signals can be. And, terminal (320) in previously received signal URLLC the signals region of LLR and, be the currently received transmission signal to produce the com inning it will do.

For example, when such as also 7, terminal (320) URLLC the effects of interference area identifiers (720) mail, contact the signal number 1 region (431), number 2 region (432), number 4 region (434), number 5 region (435), and number 7 region (437) is URLLC packet (420, 425) eMBB by packet (410) corresponding to the signals is also used for the can. And, terminal (320) previously received signal number 1 region (431), number 2 region (432), number 4 region (434), number 5 region (435), and number 7 region (437) on a screen, and the com inning it will do be LLR for these regions currently received re-transmission signal.

On the other hand, previous backtransmission signal with a received signal that is not redundant new parity (parity) or cysteine (systematic) value theme tic portion can reflect disclosed.

In this case, one of the CRC fail occurs but not contact the LLR value having a value 0 in addition to the large number can be LLR regions, can be prevented from deteriorating.

On the other hand, terminal (320) from the effects of interference area including coarse region (for example, a group, a mini-slot group, or slots or the like) information about the effects of interference area identifiers (720) when receiving packets through, terminal through said blind detection (blind detection) the effects of interference area identifiers (720) soft buffer LLR values stored on said terminal estimating puncturing region can be detailed.

For example, base station (310) terminal (320) to code block (CB) unit of information about a [sep affected region (puncturing region) (720) be transmitted through a line. In this case, terminal (320) the received information (720) on said terminal (320) is stored in a per-slot basis can be estimating LLR value mini puncturing region. And, punctured LLR value sets corresponding to the mini slot 0, combining (combining) can be a newly receiving a LLR value.

Or, for example base station (310) terminal (320) to mini-slot group (mini-a slot group) unit of information about a [sep affected region (puncturing region) (720) be transmitted through a line. In this case, terminal (320) the received information (720) on said terminal (320) is stored in the mini-slot units or OFDM symbol puncturing region LLR values can be estimated. And, a mini-slot or punctured OFDM symbols punctured LLR value sets corresponding 0, LLR value (combining) combining a newly receiving a can.

To this end, terminal (320) is first base station (310) to coarse puncturing information instructed (720) during a previous received signal (i.e., areas that are not subjected to the influence of recording interference) puncturing the areas which are not LLR mean value of an absolute value of the value of the reference value can be set.

For example, one transmission block (TB: transport block) is made of several code block (CB) can be disclosed. The, base station (310) the code block (CB) puncturing information unit (720) terminal (320) by directing to pad, terminal (320) is not puncturing code block (CB) LLR for an absolute value of the value of the average reference value can be set.

Or, for example base station (310) of the mini-slot group puncturing information (720) terminal (320) by directing to pad, terminal (320) is not an absolute value of the value of the average puncturing a mini-slot groups LLR reference value can be determined.

Then, terminal (320) base station (310) the puncturing information (720) directs the puncturing area to a small area, for example OFDM symbol or mini-slot units or PRB PRB group unit or can be divided into unit. And, terminal (320) LLR corresponding regions of the absolute value of the value of the calculated mean value, x % compared to the reference value set ahead of puncturing can be judges whether areas.

If, LLR value with reference values calculated mean value of less than x %, terminal (320) puncturing the determining areas corresponding region, after which the corresponding LLR value 0, for receiving a new LLR value can be synchronized.

And, if, with reference values calculated LLR value greater than the mean value of x %, terminal (320) outputted from the frequency region in which the corresponding puncturing, after corresponding LLR intermediate value, receiving a new LLR value can be synchronized.

940 950 Step or after, or 920 determines that result in a new signal when an, terminal (320) in the 960 can be perform channel decoding. And, terminal (320) in the CRC check can 970.

The event of a successful CRC check, terminal (320) in the base station 980 (310) can be ACK message to.

And, CRC check fails, terminal (320) in the 990 base station (310) can be NACK message to. The, embodiment example the terminal (320) for receiving a current to generate video bit for LLR can. Or terminal (320) storing said 910 can be generated in the LLR. Then, terminal (320) base station corresponding to the NACK (310) receives a signal retransmission it will can.

Thus, base station (310) terminal (320) to previous HARQ retransmission packet transmission signal generated affected of interference signal processing device whether a HARQ retransmission packet number of affected and interference with the second channel by a sieve bit indicator coercive launching the application disclosed. Or, base station (310) terminal (320) even before the HARQ ACK/NACK signal from terminal (320) to the effects of interference can be information. And, base station (310) terminal (320) even before the HARQ ACK/NACK signal from terminal (320) can be transmitting eMBB to retransmission packet.

And, terminal (320) interference impact information and (HARQ) receives a retransmission packet, previous received signal is a control value affected of interference signal of different systems, number of signal interference during previous received signal which has been subjected region [...] retransmission signal decoding channel by combining a received signal can be performed.
