Power savings in Access Points (APs). Legacy 802.11 modes such as 802.11a, b, g use one transmitter/receive chain per radio. High Throughput (HT) 802.11n modes use multiple (2, 3, or more) transmit/receive chains per radio. Power consumed by the AP may be reduced by powering off unused transmit and/or receive chains. Multiple transmit chains are only powered up when HT 802.11n transmissions requiring them are made. Using protected mode signaling, the AP powers up multiple receive chains needed for HT 802.11n reception on receiving an RTS packet indicating that an 802.11n client wishes to send 802.11n HT data. Transmit and/or receive chains may be powered up with minimum on times.

Disclosed are channel management methods in a multicarrier structure in a mobile communication system. Uplink (UL) and downlink (DL) channel management methods in a carrier aggregation environment are used as the channel management methods. In DL, a base station determines a component carrier (CC) of an unstable radio channel state, stops data retransmission by the CC, and notifies a terminal of retransmission stop. In UL, the base station determines a CC of an unstable radio channel state and instructs the terminal to stop data retransmission by the CC, and the terminal stops the data retransmission and initializes a retransmission buffer. Using the channel management methods in the mobile communication system employing the multicarrier structure, an increase in the number of unnecessary retransmissions is prevented, so that unnecessary retransmission and power consumption of the terminal can be reduced and the waste of radio resources and the degradation of base station performance due to unnecessary retransmission can be prevented.

Принадлежит: Denso Corp, Nippon Soken Inc

In a communication system, plural nodes are communicably connected to a communication line and mutually communicate based on an NRZ (Non Return to Zero) code. Each node detects, as a data frame head, a dominant level when a signal on the line changes to a dominant level during a stand-by state of the line. An activation frame is transmitted during a sleep mode. The activation frame has an activation pattern area storing therein a bit pattern showing that the frame is the activation frame, a specific pattern area storing therein a bit pattern showing a node to be activated, a boundary position satisfying a predetermined boundary condition and being a boundary between the activation and specific pattern areas. Each node performs a switchover from the sleep mode to a normal mode based on the bit patterns in the activation and specific pattern areas and information given by the boundary position.

DC Power Control for Power Amplifiers

Номер: US20120052823A1
Автор: Andreas Langer
Принадлежит: INFINEON TECHNOLOGIES AG

Some embodiments of the present disclosure relate to transmission techniques that result in power savings relative to previous solutions. These techniques often transmit a signal-of-interest by using two paths, namely, a transmission path (which includes a power amplifier) and a control path. The signal-of-interest is evaluated in “fast-track” fashion on the control path, such that the control path can “tune” a DC supply signal provided to the power amplifier. Thus, when a delayed version of the signal-of-interest is provided over the transmission path to the power amplifier, the DC supply signal provided to the power amplifier helps ensure that the power amplifier has “just enough” DC supply to ensure reliable operation without dissipating excess power. In this way, the techniques disclosed herein help to reduce power consumption in transmitters, thereby potentially helping to extend battery life and reduce undesired heating for users.

An application-specific power management technique may establish a separate power-down interval for one or more applications based on user interaction with the one or more applications. In some implementations, during use of a particular application, when a management component determines that a period of user inactivity has become greater than or equal to the particular power-down interval established for the particular application, the management component may initiate a power down of one or more components, such as a display.

A method of scheduling wireless data transmissions between a mobile terminal and a base station using multiple system carrier signals is disclosed. The method comprises the steps of receiving ( 101 ) the mobile terminal information from the base station indicating available system carriers; detecting ( 102 ) at least one dynamic parameter indicative of the mobile terminal's current capability to handle non-contiguous system carriers; determining ( 103 ) from the dynamic parameter whether a situation has occurred where the mobile terminal's capability to handle non-contiguous system carriers has been reduced; modifying ( 104 ), in such case, feedback information to be transmitted to the base station; and transmitting ( 105 ) the modified feedback information to the base station. By modifying the feedback information in this way the mobile terminal reduces the likelihood that the base station allocates non-contiguous system carriers to the mobile terminal in situations where it has a reduced capability of handling such system carriers.

Packet-level erasure protection coding in aggregated packet transmissions

Номер: US20120117446A1
Принадлежит: Qualcomm Inc

In a first aspect, an aggregated packet (A-MPDU) includes packets (MPDUs) and EC-Blocks (Error Correction Blocks) containing error correction coding information. A transmitter uses a Fountain coding scheme (for example, Raptor or RaptorQ) to generate the error correction coding information from the MPDUs. If a receiver detects an error in a received MPDU, then the receiver uses the error correction coding information from the EC-Blocks to correct the error. In a second novel aspect, a determination is made as to whether a change in error rate is more likely due to collisions or to a low SNR. If the determination is that the change is due to collisions then the MCS index is adjusted to restore a target error rate, whereas if the determination is that the change is due to a low SNR then the number of EC-Blocks per A-MPDU is adjusted to restore the target error rate.

Semiconductor memory device and method of controlling the same

Номер: US20120120739A1
Принадлежит: Fujitsu Semiconductor Ltd

An internal voltage generator when activated, generates an internal voltage to be supplied to an internal circuit. Operating the internal voltage generator consumes a predetermined amount of the power. In response to a control signal from the exterior, an entry circuit inactivates the internal voltage generator. When the internal voltage generator is inactivated, the internal voltage is not generated, thereby reducing the power consumption. By the control signal from the exterior, therefore, a chip can easily enter a low power consumption mode. The internal voltage generator is exemplified by a booster for generating the boost voltage of a word line connected with memory cells, a substrate voltage generator for generating a substrate voltage, or a precharging voltage generator for generating the precharging voltage of bit lines to be connected with the memory cells.

A system for measuring and analyzing radio frequency power proximate and within a wireless field device mesh network. A centralized software module (CSWM) collects and analyzes values from one or more wireless devices of the wireless field device mesh network representing received RF power measurements on an assigned RF channel and values representing corresponding times of the received RF power measurements. Each wireless device measures received RF power on the assigned RF channel at times other than during reception of a signal resulting in transmission by the wireless device of either an acknowledgment signal or a non-acknowledgement signal. Values representing the received RF power measurements and the corresponding times of the received RF power measurements are determined from the stored received RF power measurements and corresponding times and then discarded. These values are stored within the wireless device until successfully reported. A network manager coordinates communication between the wireless devices and synchronizes the corresponding times of received RF power measurement throughout the wireless field device mesh network.
