Abstract
For example, a first wireless station may be configured to perform hybrid beamforming training including simultaneously communicating a first plurality of spatially multiplexed Synchronization Signals (SS) beamformed in a plurality of wide beam directions; and simultaneously communicating a second plurality of spatially multiplexed SS beamformed in a plurality of narrow beam directions, which correspond to one or more reported wide beam directions.
Claims25
An apparatus comprising circuitry and logic configured to cause a first wireless station to:
- during first hybrid beamforming training, simultaneously transmit, via a plurality of Radio Frequency (RF) chains of the first wireless station, a first plurality of spatially multiplexed Synchronization Signals (SS) beamformed in a plurality of wide beam directions;
- process one or more first feedback messages from one or more second wireless stations, to identify one or more reported wide beam directions of the plurality of wide beam directions;
- during a second hybrid beamforming training, simultaneously transmit, via the plurality of RF chains of the first wireless station, a second plurality of spatially multiplexed SS beamformed in a plurality of narrow beam directions, which correspond to the one or more reported wide beam directions;
- process one or more second feedback messages from the one or more second wireless stations, to identify one or more reported narrow beam directions of the plurality of narrow beam directions;
- and
- transmit to the one or more second stations according to a beamforming scheme based on the reported narrow beam directions.
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 computer processor, enable the at least one computer processor to implement operations at a first wireless station, the operations comprising:
- during first hybrid beamforming training, simultaneously transmitting, via a plurality of Radio Frequency (RF) chains of the first wireless station, a first plurality of spatially multiplexed Synchronization Signals (SS) beamformed in a plurality of wide beam directions;
- processing one or more first feedback messages from one or more second wireless stations, to identify one or more reported wide beam directions of the plurality of wide beam directions;
- during a second hybrid beamforming training, simultaneously transmitting, via the plurality of RF chains of the first wireless station, a second plurality of spatially multiplexed SS beamformed in a plurality of narrow beam directions, which correspond to the one or more reported wide beam directions;
- processing one or more second feedback messages from the one or more second wireless stations, to identify one or more reported narrow beam directions of the plurality of narrow beam directions;
- and
- transmitting to the one or more second stations according to a beamforming scheme based on the reported narrow beam directions.
An apparatus comprising circuitry and logic configured to cause a first wireless station to:
- during first hybrid beamforming training, simultaneously process, via a plurality of Radio Frequency (RF) chains of the first wireless station, reception of one or more first spatially multiplexed Synchronization Signals (SS) from a second wireless station over a plurality of wide beam directions;
- select a reported wide beam direction of the plurality of wide beam directions, based on the one or more first SS;
- transmit to the second wireless station a first feedback message to identify the reported wide beam direction;
- during a second hybrid beamforming training, simultaneously process, via the plurality of RF chains of the first wireless station, reception of one or more second spatially multiplexed SS from the second wireless station over a plurality of narrow beam directions, which correspond to the reported wide beam direction;
- select a reported narrow beam direction of the plurality of narrow beam directions, based on the one or more second SS;
- and
- transmit to the second wireless station a second feedback message to identify the reported narrow beam direction.
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 computer processor, enable the at least one computer processor to implement operations at a first wireless station, the operations comprising:
- during first hybrid beamforming training, simultaneously processing, via a plurality of Radio Frequency (RF) chains of the first wireless station, reception of one or more first spatially multiplexed Synchronization Signals (SS) from a second wireless station over a plurality of wide beam directions;
- selecting a reported wide beam direction of the plurality of wide beam directions, based on the one or more first SS;
- transmitting to the second wireless station a first feedback message to identify the reported wide beam direction;
- during a second hybrid beamforming training, simultaneously processing, via the plurality of RF chains of the first wireless station, reception of one or more second spatially multiplexed SS from the second wireless station over a plurality of narrow beam directions, which correspond to the reported wide beam direction;
- selecting a reported narrow beam direction of the plurality of narrow beam directions, based on the one or more second SS;
- and
- transmitting to the second wireless station a second feedback message to identify the reported narrow beam direction.
