Abstract
A method in a transmitter station for establishing a wireless link with a receiver station includes: sending beamforming training data to the receiver station; responsive to sending the beamforming training data, receiving from the receiver station: beamforming feedback data; and a beamforming feedback mode indicator selected from (i) a multi-subcarrier feedback mode, and (ii) a single carrier feedback mode; when the beamforming feedback mode indicator corresponds to the single carrier feedback mode, obtaining beamforming parameters based on the beamforming feedback data.

A method in a transmitter station for establishing a wireless link with a receiver station, the method comprising:
- sending beamforming training data to the receiver station;
- responsive to sending the beamforming training data, receiving from the receiver station:
- beamforming feedback data;
- and
- a beamforming feedback mode indicator selected from (i) a multi-subcarrier feedback mode, and (ii) a single carrier feedback mode;
- when the beamforming feedback mode indicator corresponds to the single carrier feedback mode, obtaining beamforming parameters based on the beamforming feedback data.
A method in a receiver station device for establishing a wireless link with a transmitter station, comprising:
- receiving beamforming training data from the transmitter station;
- determining an active beamforming mode selected from (i) a multi-subcarrier feedback mode, and (ii) a single carrier feedback mode;
- responsive to determining that the active beamforming mode is the single carrier feedback mode, generating an uncompressed time-domain channel representation based on the beamforming training data;
- and
- sending, to the transmitter station, (i) beamforming feedback data based on the an uncompressed time-domain channel representation, and (ii) an indicator of the active beamforming mode.
A wireless communication device comprising:
- an antenna assembly;
- and
- a controller coupled to the antenna assembly, the controller configured to:
- send beamforming training data to a receiver station via the antenna assembly;
- responsive to sending the beamforming training data, receive from the receiver station:
- beamforming feedback data;
- and
- a beamforming feedback mode indicator selected from (i) a multi-subcarrier feedback mode, and (ii) a single carrier feedback mode;
- when the beamforming feedback mode indicator corresponds to the single carrier feedback mode, obtain beamforming parameters based on the beamforming feedback data.
