Abstract
Disclosed are methods for codebook sub-sampling. In various implementations, a wireless terminal receives a reference signal, determines, based on the reference signal, a first precoding index ifor a first subband and a second precoding index i'for a second subband. The wireless terminal transmits a representation of iand a representation of i′to a base station. In various implementations, i′belongs to the set Swhich, in one implementation, equals {mod(i−K+k,K), k=0, 1, . . . , K}, where K>1, and where K>1 and K>1 are integers. According to an implementation, the wireless terminal receives the reference signal from a first base station and transmits the representations of iand i′to a second base station.
