Abstract
Some demonstrative embodiments include apparatuses, devices, systems and methods of updating one or more beamforming settings of a beamformed link. For example, a first wireless station may be configured to estimate a change in an Angle of Arrival (AoA) of signals received from a second wireless station over a beamformed link between the first and second wireless stations; and to update one or more beamforming settings of the beamformed link based on the change in the AoA.
Claims25
An apparatus comprising circuitry and logic configured to cause a first wireless station to:
- estimate a change in an Angle of Arrival (AoA) of signals received from a second wireless station over a beamformed link between said first and second wireless stations;
- and
- update one or more beamforming settings of said beamformed link based on the change in the AoA, the apparatus configured to cause the first wireless station to initiate a sector sweep (SSW) procedure or a beam refinement procedure (BRP) with said second wireless station based on the change in the AoA, the apparatus configured to cause the first wireless station to transmit to said second wireless station a feedback frame to request to perform said SSW procedure or said BRP.
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 a first wireless station to:
- estimate a change in an Angle of Arrival (AoA) of signals received from a second wireless station over a beamformed link between said first and second wireless stations;
- and
- update one or more beamforming settings of said beamformed link based on the change in the AoA, the instructions, when executed, to cause the first wireless station to initiate a sector sweep (SSW) procedure or a beam refinement procedure (BRP) with said second wireless station based on the change in the AoA, the instructions, when executed, to cause the first wireless station to transmit to said second wireless station a feedback frame to request to perform said SSW procedure or said BRP.
An apparatus comprising circuitry and logic configured to cause a first wireless station to:
- transmit signals over a beamformed link between said first wireless station and a second wireless station;
- process a feedback frame from the second wireless station, the feedback frame comprising an indication of a change in an Angle of Arrival (AoA) of said signals at said second wireless station;
- and
- update one or more beamforming settings of said beamformed link based on the change in the AoA.
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 a first wireless station to:
- transmit signals over a beamformed link between said first wireless station and a second wireless station;
- process a feedback frame from the second wireless station, the feedback frame comprising an indication of a change in an Angle of Arrival (AoA) of said signals at said second wireless station;
- and
- update one or more beamforming settings of said beamformed link based on the change in the AoA.
