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: This application provides a method for transmitting a PPDU and a communication apparatus. An AP sends a trigger frame to trigger at least one STA to transmit an uplink PPDU. After receiving the trigger frame, the at least one STA transmits respective uplink PPDUs. The uplink PPDU includes a data field and LTFs. The data field is carried on a distributed RU. The LTFs are carried on all subcarriers in a first transmission bandwidth. The first transmission bandwidth is a bandwidth occupied by a distributed RU that is allocated by the AP to the at least one STA for transmitting the uplink PPDU. Alternatively, the LTFs are carried on all subcarriers of a plurality of continuous RUs corresponding to the distributed RU.

Abstract: A negotiation method for an operating mode, an initiator, a receiver, a chip system, a computer-readable storage medium, and a functional entity are disclosed. In operating mode (OM) negotiation, the initiator transmits an operating mode indication (OMI) to the responder. The OMI includes at least either of channel width indication information and space-time stream number indication information. A capability range of a channel width indicated by the channel width indication information is greater than 160 MHz. A capability range of the number of space-time streams indicated by the space-time stream number indication information is greater than 8. After receiving the OMI, the responder performs transmission with the initiator based on a negotiated OM.
