Classification: CPC H | IPC H

Claim 0:
1. A method in a user equipment for receiver selection between a baseline receiver and an alternative receiver, the method comprising:
receiving a set of reference signals;
estimating a set of channel signatures for a multiple antenna communication channel, based on the received set of reference signals;
calculating channel state information including a set of quality metrics;
in response to the set of quality metrics satisfying a criterion, selecting the baseline receiver for the multiple antenna communication channel at the user equipment;
in response to the set of quality metrics not satisfying the criterion, selecting the alternative receiver for the multiple antenna communication channel at the user equipment;
wherein, the alternative receiver for the multiple antenna communication channel at the user equipment is based on a set of integer linear combinations, where each integer linear combination is based on at least a pair of channel signatures from the estimated set of channel signatures.
