Abstract: A transmitting device for supporting Hybrid Automatic Repeat Request (HARQ) includes scrambling and encoding, in which the order of scrambling and encoding is changed compared to the conventional transmitter. Likewise, a receiving device for supporting HARQ includes descrambling and decoding, in which the order of descrambling and decoding is changed compared to the conventional receiver. In particular, the transmitting device is configured to encode at least one data unit using Forward Error Correction (FEC) coding, scramble the encoded data unit based on a scrambling seed, provide an indication of the scrambling seed that is separate from the scrambled and encoded data unit, and transmit the indication of the scrambling seed and then the scrambled and encoded data unit to the receiving device.

Abstract: A radio physical layer protocol data unit (PPDU) sending method includes: obtaining, a radio physical layer protocol data unit (PPDU), wherein the PPDU includes a high efficiency-signal field A (HE-SIG-A) and a high efficiency-signal field B (HE-SIG-B), the HE-SIG-A includes a field indicating a quantity of orthogonal frequency division multiplexing (OFDM) symbols in the HE-SIG-B, and wherein a value of the field indicates one of the following: that the quantity of OFDM symbols included in the HE-SIG-B is greater than or equal to 16, or the quantity of OFDM symbols included in the HE-SIG-B; and sending the PPDU.

Abstract: A channel access method and apparatus, where the method includes: determining, by a station, backoff duration based on a current first contention window; determining random padding duration based on a current second contention window when the backoff duration is reached; sending, on a channel, padding data whose duration is the random padding duration; detecting a state of the channel after the padding data is sent; and sending data on the channel if the state of the channel is an idle state.

Abstract: A signal field indication method and apparatus are provided. The method includes: generating, by a transmit end, a PPDU, where the PPDU includes a SIG-A indication field, and the SIG-A indication field includes at least one of a field used to indicate a number of SIG-A information symbols and a field used to indicate a SIG-A information bandwidth; and sending, by the transmit end, the PPDU. According to the method provided in this application, the transmit end may indicate different numbers of SIG-A information symbols and/or different SIG-A information bandwidths.
