Abstract: According to an example, a communication device is described comprising a receiver configured to receive a signal, a divider configured to divide the signal into signal components, an estimator configured to estimate, for each signal component, an expected processing error which is made when, instead of a first processing scheme, a second processing scheme is used to process the signal component, wherein the first has a higher processing effort than the second, a determiner configured to determine, for each signal component, whether to process the signal component by the first or by the second processing scheme based on the expected processing errors.

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.
