METHODS FOR SELECTING PRECODING VECTORS FOR MULTI POINT MIMO (MULTIPLE INPUT MULTIPLE OUTPUT) COMMUNICATIONS AND RELATED WIRELESS TERMINALS AND RADIO NETWORK NODES

摘要

A wireless terminal may receive multiple input multiple output (MIMO) downlink communications from a wireless communication network including a plurality of base station sector antenna arrays using a codebook of precoding vectors. MIMO downlink communications may be received from the wireless communication. When receiving the MIMO downlink communications as multi point MIMO downlink communications from first and second base station sector antenna arrays of the plurality of base station sector antenna arrays a precoding vector may be selected for the multi point MIMO downlink communications from only a subset of the precoding vectors of the codebook.
