Claim:
1. A method of operating a wireless terminal in a wireless communication network providing multiple-input-multiple-output (MIMO) downlink communications from a plurality of base station sector antenna arrays using a codebook of precoding vectors, the method comprising: selecting first and second precoding vectors for a multi-point MIMO downlink communication from a subset of the precoding vectors of the codebook wherein selecting the first and second precoding vectors comprises selecting the first precoding vector from the subset based on a first downlink channel from a primary sector antenna array of the wireless communication network for the wireless terminal and selecting the second precoding vector from the subset based on a second downlink channel from a secondary sector antenna array of the wireless communication network for the wireless terminal; and transmitting respective first and second identifications of the first and second precoding vectors selected for the multi-point MIMO downlink communication to the wireless communication network.
