Abstract: The present disclosure relates to Hybrid Automatic Repeat Request (HARQ) in wireless communication technologies, particularly HARQ for IEEE 802.11, i.e. HARQ for Wi-Fi. One example transmitting device is configured to encapsulate a data unit in a container unit, and encode the container unit into a codeword set of one or more codewords. One example receiving device is configured to receive, from a transmitting device, at least one codeword set of one or more codewords, decode the codewords of the codeword set to obtain a container unit, and decapsulate the container unit to obtain a data unit. A bit-size of the container unit is equal to a bit-size of the codeword set in the transmitting device and the receiving device.

Abstract: The method includes: receiving, by a second transmit end, policy information sent by a first transmit end, where the second transmit end belongs to a second BSS, the first transmit end is a transmit end that is in a first basis service set and that transmits data by using a first link, and the policy information is used to indicate a condition that the second transmit end needs to satisfy to transmit data by using a second link, or used to indicate whether the second transmit end is allowed to transmit data by using a second link; and determining, by the second transmit end based on the policy information, whether to transmit data by using the second link. According to the wireless communication method, a spatial reuse transmission policy can be adjusted dynamically based on an actual situation of a current network. This improves a system throughput.

Abstract: A pilot sequence sending method and apparatus are provided. In the disclosure, after first-time masking is performed on a pilot sequence based on a cyclic orthogonal matrix, second-time masking is performed on the pilot sequence on which first-time masking has been performed, so that a PAPR of the pilot sequence on which second-time masking has been performed is less than a PAPR of the pilot sequence on which first-time masking has been performed, and further, orthogonality of the pilot sequence on which second-time masking has been performed can be higher than that of the pilot sequence on which first-time masking has been performed. This ensures accuracy of channel estimation and frequency offset detection.
