摘要： A multi-link wireless access point (AP) is configured to exchange a plurality of frames via a plurality of setup links with a plurality of multi-link wireless non-AP stations in a wireless communication network. The multi-link wireless AP comprises a communication interface configured to send a management frame to at least one of the plurality of multi-link wireless non-AP stations operating on a first setup link, wherein the management frame comprises information for the at least one of the plurality of multi-link wireless non-AP stations for identifying at least the first setup link of the plurality of setup links to be disabled. The multi-link wireless AP further comprises a processing circuitry configured to, in response to sending the management frame, disable at least the first setup link for reducing a power required to operate at least the first setup link.

摘要： A wireless access point, AP, (110a) is disclosed, which is configured to share a transmission opportunity with at least one further wireless access point (110b) within a Multi-AP set using a Coordinated Beamforming, C-BF, scheme. The wireless AP (110a) comprises a processing circuitry (111) configured to generate a C-BF Null Data PPDU Announcement, C-BF NDPA, frame, wherein the C-BF NDPA frame comprises a Multi-AP set identifier. Moreover, the wireless AP (110a) comprises a communication interface (113) configured to transmit the C-BF NDPA frame to one or more wireless stations (120a) associated with the wireless AP (110a) and/or to one or more further wireless stations (120b) associated with the at least one further wireless AP (110b) within the Multi-AP set.

摘要： A system and method for triggering beamformed uplink (UL) physical layer protocol data units (PPDUs) are disclosed. The system comprises an access point (AP) and one or more stations (STAs). The AP sends a soliciting frame to the one or more STAs, wherein the frame comprises a null data packet, NDP, request, NDPR, indicator and receive an NDP PPDU from each of the one or more solicited STAs. The AP, then computes the precoder for each of the one or more solicited STAs and send the one or more solicited STA a trigger frame with a beamforming report. The AP receives from each of the STAs one or more beamformed UL data packets and sends a block acknowledgement to the one or more solicited STAs indicating the successful receipt of the one or more beamformed UL data packets.

摘要： 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.
