Abstract

A wireless access point (AP) is disclosed, which is configured to share a transmission opportunity with at least one further wireless access point within a Multi-AP set using a Coordinated Beamforming (C-BF) scheme. The wireless AP comprises a processing circuitry 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 comprises a communication interface configured to transmit the C-BF NDPA frame to one or more wireless stations associated with the wireless AP and/or to one or more further wireless stations associated with the at least one further wireless AP within the Multi-AP set.
