摘要： A wireless communication device is disclosed that is capable of reduced power consumption. Uplink and downlink sub-frames in a WiMAX, 802.16m or LTE environment often include several vacant symbols during which power-hungry hardware and software components need not operate at full power. By analyzing a physical layer beacon and control information of a received signal, the specific locations of data bursts can be determined, as well as periods of needed operation of a receiver module to effectively decode those data bursts. The receiver module can otherwise be controlled to operate in a LOW power state during remaining periods of vacant time, thereby conserving power consumption and extending battery life.

摘要： Improved strategies for a Cyclical Redundancy Check (CRC) are disclosed. A CRC check of a codeblock may be initiated by a CRC decoder before receiving all of the bits by a corresponding FEC encoder. Furthermore, an incremental CRC check with respect to the data packet without the need for requesting passed through data from higher layers.

摘要： The disclosure relates generally to the field of communications in transceiver, and more particularly to improved strategies for Cyclical Redundancy Check (CRC). A CRC check of a codeblock may be initiated by a CRC decoder before receiving all of the bits by a corresponding FEC encoder. Furthermore, an incremental CRC check with respect to the data packet without the need for requesting passed through data from higher layers.

摘要： A wireless receiver is disclosed that is capable of efficiently selecting a preferred transmission/detection scheme for use in wireless communication. The wireless receiver may be capable of communicating using any one of several transmission/detection schemes. Therefore, in order to select a preferred transmission/detection scheme, the wireless receiver calculates at least one metric for the transmission/detection schemes. In MIMO systems, the link adaptation is more complex and the metrics typically must be more accurate. Because of the potentially substantial amount of calculation that may be required to calculate the metric, the wireless receiver is capable of performing the individual calculations in optimized ways, as well as easily reducing the total number of metrics required to be calculated so as to reduce overall complexity.
