Abstract: Disclosed are a physical layer (PHY) protocol data unit (PPDU) transmission method and a related apparatus. The method includes: generating a PPDU, where the PPDU includes a universal signal field (U-SIG), and the U-SIG includes a subfield indicating that the PPDU is a null data packet (NDP); and sending the PPDU. In this way, a beamformee (Bfee) that receives the NDP can identify the NDP earlier. This helps improve efficiency of reading the NDP by the Bfee. The PPDU is an NDP used for a standard after 802.11ax. In a scenario in which wireless communication is performed by using the standard (for example, 802.11be) after 802.11ax, the Bfee can perform channel estimation based on the NDP.

Abstract: A device resolves a collision between its transmission and a simultaneous transmission of another device. The device is configured to interrupt its transmission, determine a negotiation signal, and determine at least one available resource to occupy with the negotiation signal during a negotiation period. Further, the device is configured to transmit the negotiation signal on the at least one available resource and simultaneously receive a negotiation signal on another resource from at least one other device during the negotiation period. Then, the device is configured to decide, based on all negotiation signals, whether to retransmit the interrupted transmission after the negotiation period.
