1. A method for use in a wireless transmit/receive unit (WTRU) for providing beamforming feedback, the method comprising: receiving a sounding frame from an access point (AP); performing a first measurement on the sounding frame; performing a singular value decomposition (SVD) on the performed first measurement; performing a Givens rotation based decomposition on the performed first measurement and quantizing each resulting angle by assigning a range to each resulting angle, wherein each range is a subset of [0, 2π]; and transmitting the quantized angles to the AP in a feedback frame.
