Abstract
A multiple-input, multiple-output (MIMO) communication system is configured to perform user scheduling with reduced channel station information. The system includes multiple terminals and at least one base station configured to communicate with the terminals. The base station is operative to obtain channel vector magnitudes for respective ones of the terminals, to identify a subset of the terminals based on the channel vector magnitudes, to obtain channel vector phase information for the identified subset of terminals, and to utilize the channel vector phase information to control transmission to the identified subset of terminals. The system may be, for example, a multi-user MIMO system in which the multiple terminals comprise autonomous single-antenna terminals.
