    Abstract: A wireless initiator access point (101) is disclosed, comprising a communication interface with an array of antennas. The communication interface is configured to operate the array of antennas with a precoding configuration for MU-MIMO communication with a plurality of wireless stations (120a-h). The communication interface is further configured to send a Null Data Packet, NDP, Announcement frame to the plurality of wireless stations (120a-h) and to trigger a wireless participator access point (111) to send a NDP frame to the plurality of wireless stations (120a-h). The communication interface is further configured to receive a plurality of Compressed Beamforming frames from the plurality of wireless stations (120a-h) and to forward the plurality of Compressed Beamforming frames to the wireless participator access point (111). Moreover, a corresponding wireless participator access point (111) is disclosed.

    Abstract: A device, method and computer product for implementing Automatic Channel Selection, ACS, in a Wireless Local Area Network, WLAN (100), is described. A plurality of network operational data sets are received, corresponding to at least two node devices (206, 208(a, b, c)) of a plurality of node devices (206, 208, 209, 210, 211) of the WLAN (100). A selection is made, based on the operational data sets, for each link of a plurality of wireless links (202(a, b, c), 204) of the WLAN (100) that are connected in series and collectively include at least one wireless backhaul link (202) that connects the at least two node devices (206, 208), a communication channel for operating the wireless link (202, 204) from a plurality of communication channels. Transmission is instructed to transmit channel identification data to operate the selection for each wireless link (202, 204).

    Abstract: The invention aims to increase the efficiency of the spatial reuse method in systems that allow multiple devices to use the same medium of a wireless network (in the same space, time and frequency). Accordingly, a system comprising a plurality of devices for a wireless network is provided. Each of the plurality of devices in the system is configured to: share an own potential transmission duration with the other devices, and perform an access method to gain direct access to a medium of the wireless network, in particular perform a CSMA/CA method, wherein the device gaining direct access to the medium is configured to: determine an shared transmission duration based on all the potential transmission durations, and publish the shared transmission duration to the other devices.
