Patent ID: 8743994

Claim:
In a system in which two devices communicate wirelessly and in which at least one of the two devices utilizes multiple antennas, a method of providing capability information pertaining to beamforming from one of the two devices, the method comprising: providing a first bit in a structure of a capability field to indicate that a first device is capable of receiving beamformed signals; providing a second bit in the structure of the capability field to indicate that a first device is capable of generating and transmitting channel parameters in full matrix form for use in beamforming; providing a third bit in the structure of the capability field to indicate that the first device is capable of generating and transmitting channel parameter unitary matrix in reduced form for use in beamforming; and providing a fourth bit in the structure of the capability field to indicate that the first device is capable of providing calibration for beamforming in the full matrix form or in the reduced form, wherein the capability field is generated by a baseband processing logic of the first device and transmitted in a wireless communication signal to a second device.
