Abstract

For example, an Access Point (AP) may be configured to determine a plurality of beamformed sectors for communication with a plurality of wireless communication stations (STAs), wherein a beamformed sector for communication with a STA is based on a beamforming training between the AP and the STA; to determine a grouping sector for communication between the AP and a group of STAs including two or more grouped STAs of the plurality of STAs, wherein the grouping sector covers two or more beamformed sectors corresponding to the two or more grouped STAs; to listen over the grouping sector for a transmission from a grouped STA of the group of STAs; and, based on the transmission from the grouped STA, to communicate a beamformed transmission with the grouped STA via a beamformed sector corresponding to the grouped STA.

Claims (44)

1 . An apparatus comprising logic and circuitry configured to cause an Access Point (AP) to:

determine a plurality of beamformed sectors for communication with a plurality of wireless communication stations (STAs), wherein a beamformed sector for communication with a STA is based on a beamforming feedback from the STA, the beamforming feedback from the STA comprises an indication of a plurality of identified sectors of the AP, which are identified by the STA based on a beamforming training between the AP and the STA;

determine a grouping sector for communication between the AP and a group of STAs comprising two or more grouped STAs of the plurality of STAs, wherein the grouping sector covers two or more beamformed sectors corresponding to the two or more grouped STAs;

listen over the grouping sector for a transmission from a grouped STA of the group of STAs; and

based on the transmission from the grouped STA, communicate a beamformed transmission with the grouped STA via a beamformed sector corresponding to the grouped STA.

2 . The apparatus of claim 1 configured to cause the AP to allocate the two or more grouped STAs to a group contention-based period, during which the two or more grouped STAs are allowed to transmit to the AP according to a contention mechanism.

3 . The apparatus of claim 2 configured to cause the AP to listen over the grouping sector during the group contention-based period.

4 . The apparatus of claim 2 , wherein the group contention-based period comprises a Target Wake Time (TWT) Service Period (SP) allocated to the group of STAs.

5 . The apparatus of claim 1 configured to cause the AP to determine a grouping sector corresponding to the STA based on the plurality of identified sectors of the AP indicated by the beamforming feedback from the STA.

6 . The apparatus of claim 1 , wherein the beamforming feedback from the STA comprises measurement information corresponding to the plurality of identified sectors of the AP, the measurement information based on measurements of the STA during the beamforming training between the AP and the STA.

7 . The apparatus of claim 1 , wherein the beamforming feedback from the STA comprises an indication of all identified sectors of the AP, which are identified by the STA based on the beamforming training between the AP and the STA.

8 . The apparatus of claim 1 configured to cause the AP to transmit a beamforming training announcement to announce a group beamforming training with the group of STAs.

9 . The apparatus of claim 1 configured to cause the AP to determine a plurality of grouping sectors for communication between the AP and a plurality of groups of STAs, the plurality of grouping sectors comprising a first grouping sector for communication between the AP and a first group of STAs, and a second grouping sector for communication between the AP and a second group of STAs.

10 . The apparatus of claim 9 , wherein the first grouping sector has no overlap with the second grouping sector.

11 . The apparatus of claim 1 configured to cause the AP to determine another grouping sector for communication between the AP and one or more other STAs of the plurality of STAs.

12 . The apparatus of claim 1 , wherein the transmission from the grouped STA comprises a control frame.

13 . The apparatus of claim 12 configured to cause the AP to, based on the control frame from the grouped STA, transmit a control response via the grouping sector, and to communicate the beamformed transmission with the grouped STA after the control response.

15 . The apparatus of claim 1 comprising at least one radio to communicate the beamformed transmission.

16 . The apparatus of claim 15 comprising one or more antennas connected to the radio, and a processor to execute instructions of an operating system of the AP.

17 . A product comprising one or more tangible computer-readable non-transitory storage media comprising computer-executable instructions operable to, when executed by at least one processor, enable the at least one processor to cause an Access Point (AP) to:

determine a plurality of beamformed sectors for communication with a plurality of wireless communication stations (STAs), wherein a beamformed sector for communication with a STA is based on a beamforming feedback from the STA, the beamforming feedback from the STA comprises an indication of a plurality of identified sectors of the AP, which are identified by the STA based on a beamforming training between the AP and the STA;
