Abstract: 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.

Abstract: A wireless transmitting device is configured to: obtain a compressed-mode PPDU that includes one or more SC fields, where each SC field corresponds to one MU-MIMO group of the one or more MU-MIMO groups and is indicative of a spatial stream configuration for user devices of that MU-MIMO group; and transmit the PPDU to the user devices of the one or more MU-MIMO groups over a predetermined BW. Further, a user device is configured to: receive a compressed-mode PPDU from a wireless transmitting device; and decode the PPDU to obtain a SC field corresponding to the MU-MIMO group that the user device belongs to.

Abstract: A channel sounding method and a channel sounding apparatus are disclosed. The method includes: A first communication apparatus sends a null data packet announcement (NDPA) frame, and sends a null data packet (NDP); and a second communication apparatus and a third communication apparatus receive the NDPA frame and the NDP. The NDPA frame includes first indication information, where the first indication information indicates that the NDPA frame is for orthogonal frequency division multiplexing multiple access (OFDMA) and non-OFDMA hybrid channel sounding, a total bandwidth of the NDP is a first bandwidth, a portion of the NDP in the first bandwidth is used by the second communication apparatus to obtain channel state information between the second and the first communication apparatus, a portion of the NDP in a second bandwidth is used by the third communication apparatus to obtain channel state information between the third communication apparatus and the first communication apparatus, the second bandwidth is a part of the first bandwidth, and the first bandwidth is greater than 80 MHz.

Abstract: A sharing access point, AP, is configured to share at least a portion of a transmission opportunity, TXOP, with one or more shared APs within a Multi-AP, M-AP, set for participating in a coordinated transmission. The sharing AP comprises a processing circuitry configured to generate a M-AP trigger frame; and a communication interface configured to transmit the M-AP trigger frame to a shared AP within the M-AP set. The M-AP trigger frame is configured to solicit the shared AP to initiate a coordination-related procedure with one or more non-AP stations associated with the shared AP and/or with one or more OBSS non-AP stations associated with one or more further shared APs within the M-AP set and to transmit a completion notification frame to the sharing AP. The communication interface is further configured to receive from the shared AP the completion notification frame indicating the completion of the coordination-related procedure.
