Methods and apparatus for improved utilization of air link resources in a wireless communications system including a multi-antenna element base station
Methods and apparatus are described for improved utilization of air link resources. A base station includes at least one of a plurality of receive antenna elements and a plurality of transmit antenna elements for communicating with a wireless terminal. The base station generates channel estimation vectors corresponding to wireless terminals using the base station, where a generated channel estimation vector includes different elements corresponding to different base station antenna elements. The base station determines a level of orthogonality between pairs of channel estimation vectors corresponding to different wireless terminals. At least some of the segments to be assigned by the base station are substantially overlapping, e.g., the segments overlap fully or to a high degree. Wireless terminal pairs which have substantially orthogonal channel estimation vectors are matched and assigned to substantially overlapping segments, and the power level associated with the segments is controlled to be substantially the same.
