摘要
Methods may be provided to operate wireless terminal in wireless communication networks providing multiple-input-multiple-output (MIMO) downlink communications from a plurality of base station sector antenna arrays using a codebook of precoding vectors. Such methods may include receiving multi-point MIMO downlink communications from the wireless communication network. When receiving the multi-point MIMO downlink communications from the wireless communication network, a precoding vector may be selected from a subset of the precoding vectors of the codebook for the multi-point MIMO downlink communications.
