摘要： A communication device maps a plurality of bits to a first set of transmission symbols corresponding to a first set of subcarriers within a component communication channel. Transmission symbols among the first set of transmission symbols correspond to respective subsets of one or more bits, and transmission symbols among the first set of transmission symbols are single carrier transmission symbols. The communication device maps the plurality of bits to a second set of transmission symbols corresponding to a second set of subcarriers within the component communication channel. At least a subset of multiple transmission symbols in the second set of transmission symbols correspond to phase adjusted versions of transmission symbols in a corresponding at least a subset of multiple transmission symbols in the first set of transmission symbols. The communication device generates a transmission signal using the first set of transmission symbols and the second set of transmission symbols.

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.
