Abstract
Provided are a spatial reuse method and apparatus. The method includes: receiving a radio frame and determining whether the radio frame carries a trigger frame configured to trigger uplink multi-user transmission according to indication information of the trigger frame in a physical signaling field of the radio frame; when the trigger frame is determined to be carried in the radio frame, receiving, by a station, the trigger frame, and acquiring first spatial reuse information of the trigger frame; at an end of a radio frame reception process, determining whether to perform first spatial reuse according to the first spatial reuse information. The present disclosure solves the problem in the related art of low spatial reuse efficiency when a station performs spatial reuse on a radio frame and achieves a technical effect of improving network performance.

21. A method, comprising:
-
receiving, by a communication node in a wireless local network, a radio frame; determining, by the wireless communication node based on indication information indicated in a physical signaling field of the radio frame, whether the radio frame corresponds to a trigger frame, wherein the indication information indicated in the physical signaling field of the radio frame includes one of spatial reuse delay information or spatial reuse restriction information; and acquiring, by the communication node, first spatial reuse information from the trigger frame. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
