摘要： This disclosure describes systems, methods, and devices related to extended range modulation and coding scheme (MCS). A device may generate a first orthogonal frequency-division multiplexing (OFDM) signal to be transmitted in a frequency band. The device may generate a second OFDM signal to be transmitted in the frequency band, wherein the second OFDM signal is a duplicate of the first signal. The device may assign a reduced number of guard intervals (GIs) to the first OFDM signal and the second OFDM signal. The device may cause to send the first OFDM signal and the second OFDM signal using the frequency band.

摘要： This disclosure describes systems, methods, and devices related to byte boundary shift. A device may utilize a probabilistic constellation shaping mechanism comprising a shaping encoder, a channel encoder, and a modulator to generate one or more QAM symbols. The device may set a shaping output block to have a fixed length of output bits. The device may set shaping input bits used in the shaping encoder, wherein the input bits are a multiple of a first number of bits.

摘要： Methods and apparatuses for arranging sounding symbol are provided. An example apparatus comprises memory; and processing circuitry coupled to the memory. The processing circuitry is configured to encode a sounding signal. The sounding signal comprises a plurality of sounding symbols, and the repetition of sounding symbols to be transmitted in sequence is avoided.

摘要： This disclosure describes systems, methods, and devices related to scrambler initialization for multi-user (MU) clear to send (CTS) transmission. A first device may identify a MU request to send (RTS) frame received from a second device. The first device may determine an initial state of a scrambler based on the first 7 bits of a service field of the MU-RTS frame. The first device may cause first data to be scrambled, using the initial state of the scrambler, resulting in second data. The first device may cause to send a MU-CTS frame that comprises the second data to the second device.
