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 i 2  for a first subband and a second precoding index i′ 2  for a second subband. The wireless terminal transmits a representation of i 2  and a representation of  4  to a base station. In various implementations, i′ 2  belongs to the set S i 2  which, in one implementation, equals {mod(i 2 −K 1 k,K), k=0, 1, . . . , K 2 }, where K 1 >1, and where K 2 >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 i 2  and i′ 2  to a second base station.
