A METHOD FOR SELECTIVE ANTENNA ACTIVATION AND PER ANTENNA OR PER ANTENNA GROUP POWER ASSIGNMENTS IN COOPERATIVE SIGNALING WIRELESS MIMO SYSTEMS

摘要

A method and apparatus is disclosed herein for selective antenna activation in cooperative signaling wireless systems. In one embodiment, the method is for use in a cooperative signaling MIMO system in which antennas are located a plurality of different locations across a geographic area, the system comprising a plurality of different cooperative MIMO controllers and a plurality of antennas that can be communicably coupled to each of the controllers, the method comprising: at different transmission instances, selectively activating one or more antennas in the cooperative signaling MIMO system to vary which subset of antennas are active among antennas that can be used for each of the controllers in the system, including applying a power pattern which specifies per antenna or per antenna group power assignments for the one or more antennas being selectively activated, and performing cooperative MIMO transmission under control of at each controller in conformance with antenna activation and antenna power assignments assigned for each transmission time.
