    Abstract: An access point, AP (110), configured to perform a sounding procedure with one or more associated non-AP stations (120) in a wireless local area network (100) is provided. The AP (110) comprises a processing circuitry (111) configured to generate a null data PPDU announcement, NDPA, frame, wherein the NDPA frame comprises for each of the one or more associated non-AP stations (120) a station info field. The station info field comprises a partial BW info subfield, including a feedback bitmap and an indication of a resolution and/or a range of the feedback bitmap with a 20 MHz or 40 MHz subchannel resolution for a Sounding NDP with a bandwidth of up to 320 MHz. The AP (110) further comprises a communication interface (113) configured to transmit the NDPA frame to the one or more associated non-AP stations (120). Moreover, a corresponding non-AP station (120) is disclosed.

    Abstract: The method includes: receiving, by a second transmit end, policy information sent by a first transmit end, where the second transmit end belongs to a second BSS, the first transmit end is a transmit end that is in a first basis service set and that transmits data by using a first link, and the policy information is used to indicate a condition that the second transmit end needs to satisfy to transmit data by using a second link, or used to indicate whether the second transmit end is allowed to transmit data by using a second link; and determining, by the second transmit end based on the policy information, whether to transmit data by using the second link. According to the wireless communication method, a spatial reuse transmission policy can be adjusted dynamically based on an actual situation of a current network. This improves a system throughput.
