摘要： In a transmission method according to one aspect of the present disclosure, a encoder performs error correction coding on an information bit string to generate a code word. A mapper modulates a first bit string in which the number of bits is the predetermined integral multiple of (X+Y) in the code word using a first scheme, the first scheme being a set of a modulation scheme in which an X-bit bit string is mapped to generate a first complex signal and a modulation scheme in which a Y-bit bit string is mapped to generate a second complex signal, and modulates a second bit string in which the first bit string is removed from the code word using a second scheme different from the first scheme.

摘要： A WLAN system resource indication method and apparatus are provided. The method includes: generating, by an access point, a frame that carries resource indication information; and sending, to multiple stations, the frame that carries the resource indication information. The resource indication information includes multiple pieces of sub resource indication information. Correspondingly, each piece of the sub resource indication information uniquely corresponds to one of the multiple stations. Therefore, a station side does not need read the entire resource indication information, so as to reduce resource overheads and improve efficiency.

摘要： Two-way (full-duplex) wireless communications. Various embodiments measure interference channels and provide for interference cancellation in both analog and digital domains to mitigate self-interference. The system supports multiple clients wherein new clients can join the network asynchronously, and also supports Multiple-Input Multiple-Output (MIMO) antennas.

摘要： For example, an EDMG STA may be configured to generate a plurality of spatial streams of an EDMG PPDU; map the plurality of spatial streams to a respective plurality of pairs of space-time streams according to an STBC scheme by mapping a first data sequence of a spatial stream to a first symbol in an odd numbered space-time stream, mapping a second data sequence of the spatial stream to a second symbol in the odd numbered space-time stream, mapping a sign inverted complex conjugate of the second data sequence to a first symbol in an even numbered space-time stream, and mapping a complex conjugate of the first data sequence to a second symbol in the even numbered space-time stream; and transmit a transmission comprising the plurality of pairs of space-time streams over a channel bandwidth in a frequency band above 45 Gigahertz (GHz).

摘要： Aspects of the disclosure relate to wireless communication systems configured to provide techniques for utilizing a one-symbol space-time block code (STBC) process to encode control information for transmission on an uplink control channel. The one-symbol STBC process produces two code blocks, each for transmission on a different antenna. Each code block may be time domain spread across multiple single-carrier frequency division multiple access (SC-FDMA) uplink control channel symbols using the same spreading code to enable recovery of the code blocks at the receiver.
