A trigger frame is generated at the first communication device to trigger an uplink orthogonal frequency division multiple access (OFDMA) transmission of beamforming training feedback from at least some of the multiple second communication devices. After transmission of the beamforming training packet by the first communication device, the trigger frame is transmitted to the at least some of the multiple communication devices. The uplink OFDMA transmission is then received at the first communication device. The uplink OFDMA transmission includes respective beamforming training feedback packets generated based on the beamforming training packet by respective ones of the at least some of the multiple second communication devices. The respective beamforming training feedback packets are simultaneously transmitted by the at least some of the multiple second communication devices.

摘要： A first communication device receives, from a second communication device, a trigger frame. The first communication device generates a single-user (SU) physical layer (PHY) protocol data unit that includes a PHY protocol payload, wherein the PHY protocol payload include information other than information that acknowledges a previous transmission from the second communication device. In response to the trigger frame, the first communication device transmits the SU PHY protocol data unit to the second communication device, such that the SU PHY protocol data unit is transmitted prior to the first communication device transmitting any other PHY protocol data unit after receiving the trigger frame.

摘要： Techniques are provided for transmitting and receiving a mother code in an incremental redundancy hybrid automatic repeat request protocol. A set of information bits corresponding to a message may be encoded and interleaved to produce the mother code. Each bit position of the mother code may be mapped to an output symbol, and each output symbol may be mapped to an antenna for transmission. One or more transmissions of symbols contained in the output symbols may be performed, where each transmission may include puncturing the mother code by selecting one or more symbols from the of output symbols, and transmitting each symbol in the one or more symbols on an antenna corresponding to that symbol. The mother code may be decoded, in part, by determining combinable bits contained within a set of received symbols, and computing one or more log likelihood ratio values corresponding to each symbol in the set of received symbols.
