Abstract: This application provides a communication method and apparatus to reduce impact of channel contention of a first STA on a scheduled STA in an OBSS by restricting channel access of the first STA in a BSS in which a first AP is located, so as to increase a success rate of obtaining a channel by the scheduled STA in the OBSS. In the method, the first AP generates a first frame, where the first frame includes r-TWT SP information and first indication information, the first indication information indicates that the r-TWT SP information is r-TWT SP information of an OBSS of a BSS in which the first AP is located, the r-TWT SP information of the OBSS indicates whether the first STA is to terminate a TXOP at a start time indicated by the r-TWT SP information of the OBSS.

Abstract: This application provides a communication method and apparatus, to resolve a problem that retransmitted MPDUs with different RVs cannot be transmitted in a same transmission process, and improve data transmission efficiency. The communication method and apparatus may be applied to a data retransmission process between any two nodes in a Wi-Fi system. The method includes: When a PPDU sent by a first node includes one or more retransmitted MPDUs, the first node may include, in the PPDU, RV indication information used to indicate an RV of each retransmitted MPDU, so that a second node receives each retransmitted MPDU based on the RV indication information.

Abstract: This application relates to a communication method, a communication device, and a computer-readable storage medium. In the communication method, a second device receives a third protocol data unit from a first device. The third protocol data unit includes a second frame, and the second frame indicates that a first time period in a transmission opportunity of the first device is allocated for data transmission of the second device. The second device transmits a fourth protocol data unit to a third device within the first time period. A duration field in the fourth protocol data unit is set, so that a basic network allocation vector associated with the fourth device is 0 when the first time period ends. In this way, the fourth device can respond to triggering, thereby improving system efficiency.
