摘要： This application relates to the field of wireless communication, and is applied to a wireless local area network that supports the 802.11 series standards such as the 802.11bf standard, and in particular, to a measurement setup identifier determining method and a related apparatus. The method includes: A requesting station requests an AP as a proxy of the requesting station to perform sensing measurement. The AP obtains parameters used by the AP and a sensing responder in a proxy sensing procedure, and identifies the parameters. The AP uses an identifier different from an existing identifier at the AP when identifying the parameters. The AP then sends the parameters and the identifier to the sensing responder.

摘要： This application provides a resource unit indication method, an access point, and a station. In the method, a resource unit allocation subfield in a trigger frame includes a frequency band range indication and a resource unit indication. The resource unit indication is used to indicate an MRU allocated to a station. The frequency band range indication is used to indicate a frequency band range in which an RU in the MRU is located. For example, the frequency band range indication is used to indicate 80 MHz in which a smallest RU in the MRU is located. In this way, the frequency band range indication indicates a frequency band range related to the MRU, and can further carry more information, for example, the frequency band range in which the smallest RU is located. It may be learned that this application may be applied to 802.11ax, 802.11be, and a future Wi-Fi system.

摘要： This application provides data transmission methods and apparatuses, to introduce a buffer status report (BSR) mechanism through multi-link (ML) cooperation, to improve performance of scheduling a station by an ML device. In an example method, a multi-link transmit end determines BSR signaling sent to a multi-link receive end, where the BSR signaling can enable the multi-link receive end to schedule a station of the multi-link transmit end over one or more links. Further, the multi-link transmit end sends the B SR signaling to the multi-link transmit end over the one or more links. This introduces a BSR mechanism through ML cooperation.

摘要： This application provides a communication method and apparatus, and relates to the communication field. The method includes: generating a physical layer protocol data unit PPDU, where the PPDU includes a first field indicating that the PPDU is an extremely high throughput sounding null data packet EHT sounding NDP transmitted based on orthogonal frequency division multiple access OFDMA, the PPDU further includes an extremely high throughput-long training field EHT-LTF and a packet extension PE field, and the PE field is adjacent to the EHT-LTF; and sending the PPDU. In this way, a Bfee may determine, based on the first field in the PPDU, that the PPDU is the EHT sounding NDP transmitted based on OFDMA, perform channel estimation by using the PPDU, and feed back channel state information to a Bfer, to implement functions such as beamforming and resource scheduling for OFDMA transmission, thereby improving channel quality and a throughput.
