Title: SYSTEM AND METHOD FOR COMMUNICATING IN A WIRELESS COMMUNICATIONS SYSTEM WITH PRECODING
Abstract:
A method for precoded communications includes precoding in a first stage, outgoing data streams with first precoding matrices generated in accordance with instantaneous channel feedback received from receiving devices, wherein a configuration of the instantaneous channel feedback is determined in accordance with statistical channel information and individual of the receiving devices, thereby producing first precoded data streams, precoding in a second stage, the first precoded data streams with second precoding matrices generated in accordance with the statistical channel information associated with the receiving devices, thereby producing second precoded data streams, and transmitting the second precoded data streams to the receiving devices.
