Limited duty cycle fdd system

Номер: US20120002578A1
Автор: Peter Gaal, Tingfang JI
Принадлежит: Qualcomm Inc

Acknowledgment bundling has been defined for Long Term Evolution (LTE) Time Division Duplex (TDD) systems due to asymmetric DL/UL partitioning. In the case of Frequency Division Duplex (FDD) with a limited uplink (UL) duty cycle, there may be asymmetry associated with a downlink transmission and an associated uplink acknowledgment. For example, there may be a physical downlink shared channel (PDSCH) and a physical uplink control channel (PUCCH) hybrid automatic repeat request acknowledgment (HARQ-ACK) asymmetry. Interference between downlink and uplink transmissions may be a factor contributing to the limited UL duty cycle in an FDD system. For an FDD system having a limited mobile transmission duty cycle, both DL and UL performance may be significantly degraded without proper mitigation techniques. According to certain embodiments of the present disclosure, various HARQ and scheduling techniques may be utilized for minimizing loss due to the limited UL duty cycle.

Embodiments are directed to binary phase shift key modulating a first pilot symbol according to a reference sequence, and differentially binary phase shift key modulating a second pilot symbols. The original reference sequence and the delayed differentially modulated sequence are then combined before performing an Inverse Fast Fourier Transform and inserting a guard interval. Receiver operations are an inverse of the transmitter operations, which were just discussed. The receiver does not have to know the reference sequence. Embodiments are directed to specifying a plurality of seeds that are bit patterns each having r bits not all of which have a value of zero, extending the seeds into respective sequences by applying to each seed a recurrence formula; and using one of the sequences as a comb sequence and using the sequences other than the comb sequence as binary phase shift keying patterns.

Low cost high speed data cable

Номер: US20120012359A1
Автор: David William Mc Gowan, Gerald Donal Murphy, John Martin Horan
Принадлежит: Redmere Tech Ltd

A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable. The raw cable is constructed with either Shielded Twisted Pairs (STP) or coaxial lines which carry all signals on either shielded conductors or their shields. Some auxiliary signals including power are carried on ungrounded shields. This achieves a reduction in the number of wires in the cable leading to a thinner, lighter, and less costly HDMI or DisplayPort Cable. The use of a uniform technology, either STP or coax, also permits simpler and lower cost production and assembly of the cable.

A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI), and includes a raw cable and a boost device. Each of four high speed video signals is carried on the inner conductors of a pair of coaxial lines in the raw cable. The boost device receives only one of the polarities of one of the high speed video signals, and generates a differential signal therefrom. Lower speed signals are carried on the galvanically or capacitively coupled shields of a pair of coaxial lines, thus permitting fourteen HDMI signals to be carried in a cable comprising only eight coaxial lines, resulting in a simpler and lower cost production and assembly of the cable.

A method for allocating resources for a scheduling request indicator (SRI) is disclosed. An SRI cycle period for use by user equipment (UE) within a cell is transmitted from a NodeB in a cell to UE within the cell. The NodeB transmits a specific SRI subframe offset and an index value to the particular UE within the cell.

Assessment of on-chip circuit based on eye-pattern asymmetry

Номер: US20120025889A1
Автор: Jianghui Su
Принадлежит: Oracle International Corp

During an asymmetry testing mode of an integrated circuit, the asymmetry of an on-chip I/O circuit is tested. In particular, a transmitter circuit in the integrated circuit transmits electrical signals, which are associated with a predefined data pattern, to a receiver circuit in the integrated circuit via a communication channel (such as a differential pair of signal lines). Then the integrated circuit generates an eye pattern using the received electrical signals, and determines an asymmetry of the eye pattern about a common reference level of the received electrical signals. Furthermore, the integrated circuit performs remedial action based on the determined asymmetry. For example, the integrated circuit may compare the determined asymmetry with a predefined asymmetry criterion and, if the asymmetry exceeds the predefined asymmetry criterion, may output a result of the comparison that indicates a failure of the asymmetry test.

Disclosed in the present invention is a method for a base station to set a backhaul link subframe for a relay node in a wireless communication system, to which a carrier aggregation technique is applied. More particularly, the present invention comprises the steps of: determining one of the plurality of subframe settings as a first subframe setting for a main component carrier allocated to the relay node; composing subframe setting candidates for one or more subcomponent carriers allocated to the relay node, one the basis of the determined first subframe setting; and determining a second subframe setting for each of the one or more subcomponent carriers, using the composed subframe setting candidates, wherein a subframe aggregation according to the first subframe setting and subframe aggregations according to each of the subframe setting candidates do not overlap when downlink subframes and uplink subframes of the different component carriers are identical, and a downlink subframe aggregation according to the second subframe setting is included in a downlink subframe aggregation according to the first subframe setting. 1. A method for processing signals at a user equipment in a TDD (Time Division Duplex) wireless communication system , the method comprising:configuring a first subframe configuration to a primary cell and a second subframe configuration to a secondary cell;receiving downlink control information via the primary cell and receiving downlink data using the downlink control information via the secondary cell, from a network at a first subframe; andtransmitting uplink control information corresponding to the downlink data via the primary cell to the network at a second subframe,wherein the first subframe configuration is different from the second subframe configuration,wherein a relationship between the first subframe and the second subframe is defined based on the first subframe configuration.2.

One embodiment of the present invention relates to a method for transmitting signals over an unlicensed band phase of a base station in a wireless communication system, which comprises the steps of: transmitting a physical down-link control channel (PDCCH) from a licensed band; and transmitting a physical down-link shared channel (PDSCH) over a time interval of the unlicensed band corresponding to the sub-frame transmitted by the PDCCH, wherein a reservation signal can be transmitted to a pre-set point from the point the unlicensed band is available to the base station, if the base station performs wave transmission sensing for the unlicensed band for transmission of the PDSCH, and the pre-set point is earlier than the point at which the unlicensed becomes available from the transmission sensing results. 1. A method of transmitting a signal on an unlicensed band , which is transmitted by an eNode B in a wireless communication system , comprising the steps of:transmitting a physical downlink control channel (PDCCH) on a licensed band; andtransmitting a physical downlink shared channel (PDSCH) on a time period of the unlicensed band corresponding to a subframe to which the PDCCH is transmitted;wherein the eNode B is configured to perform a carrier sensing for the unlicensed band to transmit the PDSCH and wherein if a timing point of which the unlicensed band is available is ahead of a pre-set timing point as a result of performing the carrier sensing, the eNode B is configured to transmit a reservation signal from the timing point of which the unlicensed band is available to the pre-set timing point.2. The method of claim 1 , wherein if a scheduling of the PDSCH is performed after the carrier sensing claim 1 , the pre-set timing point corresponds to a transmission start point of the subframe to which the PDCCH is transmitted.3. The method of claim 1 , wherein if the carrier sensing is performed after a scheduling of the PDSCH claim 1 , the pre-set timing point ...
