1. A method for beamforming feedback comprising:
- receiving a sounding packet for a beamforming transmission;
performing planar rotation in accordance with the sounding packet to generate phi and psi angle values;
quantizing the phi and psi angle values such that a quantized resolution of the phi angle value is different from a quantized resolution of the psi angle value; and
feeding back the quantized phi and psi angle values.
