Abstract: This application provides a beam training method and apparatus. The method includes: generating and sending a set up frame, where the set up frame includes M pieces of time information, each piece of time information corresponds to one receiving device in the M receiving devices, each piece of time information is used to indicate a feedback information sending moment of the corresponding receiving device, each piece of time information is further used to indicate an acknowledgment information receiving moment of the corresponding receiving device; receiving a sector sweep SSW frame, generating feedback information based on the SSW frame; sending the feedback information at a feedback information sending moment indicated by corresponding time information; receiving, at an acknowledgment information receiving moment indicated by the corresponding time information, acknowledgment information. Therefore, a training time can be shortened and signaling overheads can be reduced.

Abstract: Embodiments of the present application provide a spatial reuse method. The method includes: receiving, by a first node in BSS1, a measurement request sent by a second node in BSS2, where one or more first service periods SP1 are allocated in the BSS1, one or more second service periods SP2 are allocated in the BSS2, and the measurement request is used to request to measure the one or more second service periods SP2; receiving, by the first node in the BSS1, a measurement report of the second node in the BSS2, where the measurement report is a report of measuring the one or more first service periods SP1; and determining, by the first node in the BSS1 based on the received measurement report, whether to allow spatial reuse of the one or more first service periods SP1 and the one or more second service periods SP2.
