Abstract
A method implemented in a communication device includes receiving a first beamforming training transmission corrupted by a collision, determining a first station to which the first beamforming training transmission corresponds based on the first beamforming training transmission corrupted by the collision, and in response to determining the first station, transmitting a signal to the first station to prompt the first station to transmit a second beamforming training transmission.
Claims20
A method implemented in a communication device, the method comprising:
- receiving, at the communication device, a first beamforming training transmission corrupted by a collision;
- determining, at the communication device, a first station to which the first beamforming training transmission corresponds based on the first beamforming training transmission corrupted by the collision;
- and
- in response to determining the first station, transmitting, by the communication device, a signal to the first station to prompt the first station to transmit a second beamforming training transmission.
An apparatus comprising:
- a transceiver coupled to a plurality of antennas;
- and
- a controller configured to
- determine, based on a received first beamforming training transmission, a first station to which the first beamforming training transmission corresponds, wherein the first beamforming training transmission is corrupted by a collision, and
- in response to determining the first station, cause the transceiver to transmit a signal to the first station to prompt the first station to transmit a second beamforming training transmission.
A tangible, non-transitory computer-readable memory storing instructions that, when executed by a processor, cause the processor to:
- determine, based on a received first beamforming training transmission, a first station to which the first beamforming training transmission corresponds, wherein the first beamforming training transmission is corrupted by a collision;
- and
- in response to determining the first station, cause a signal to be transmitted to the first station to prompt the first station to transmit a second beamforming training transmission.
