摘要
A multiple-input, multiple-output (MIMO) communication system is configured to perform user scheduling and associated precoding. 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 vectors for respective ones of the terminals, to select a subset of the terminals based on magnitudes of the respective channel vectors, to compute a precoding matrix using the channel vectors of the selected subset of terminals, and to utilize the preceding matrix to control transmission to the selected subset of terminals. The system may be, for example, a time-division duplex (TDD) multi-user MIMO system in which the multiple terminals comprise autonomous single-antenna terminals.
