METHOD AND SYSTEM FOR GENERATING ANTENNA SELECTION SIGNALS IN WIRELESS COMMUNICATION NETWORK

摘要

A method and system generating signal to select a subset of antennas from a set of antennas to transmit user data in a wireless communication system. First signals (e.g. user data) are transmitted during a first transmission time intervals (TTI) using a first subset of antennas. Second signals (e.g. pilot tones) are transmitted during a second TTI using a second subset of antennas. Corresponding channels are estimated for the first subset of antennas and the second subset of antennas from the user data and the pilot tones. Then, based on the estimating, an optimal subset of antenna is selected from the first subset of antennas and the second subset of antennas to transmit the user data during a sequent TTI, and in which the selecting is performed adaptively.
