CHANNEL ACCESS METHOD IN CONTENTION PERIOD, RELATED DEVICE, AND SYSTEM

摘要

Disclosed in embodiments of the present invention are a channel access method in a contention period, a related device, and a system. The method comprises: a first station (STA) sends an RTS frame to a second STA, the RTS frame carrying an idle first link and bandwidth information of a first idle channel corresponding to the first link; receive a CTS frame fed back by the second STA, the CTS frame carrying link information of a second link and bandwidth information of a second idle channel corresponding to the second link; and sending data to the second STA on a third idle channel corresponding to a third link, the third link being determined by link information of the second link. In this way, a second transmission opportunity (TXOP) can be established on channels of the first STA and the second STA that are both idle, so as to reuse the first TXOP and the second TXOP in frequency and space.
