Abstract:
A method and apparatus for receive beam-forming in an analog domain. A user equipment may perform channel estimation for obtaining a set of channel responses for a plurality of antennas of the UE. The UE may determine a beamforming codeword for receive beamforming based on the set of channel responses. The UE may apply a training codeword to the received signal in analog domain. The training codeword includes phase adjustment coefficients for each antenna and a different training codeword may be applied for each channel observation. The UE may measure a metric for at least one candidate codeword based on the set of channel responses and determine the beamforming codeword based on the metric.
