METHOD AND APPARATUS FOR WIDEBAND TRANSMISSION BASED ON MULTI-USER MIMO AND TWO-WAY TRAINING

摘要

A method, apparatus and system is disclosed herein for wireless transmission based on MU-MIMO and two-way training. In one embodiment, the system comprises a set of K receivers and at least one transmitter having a set of N transmit antennas, where the transmitter is operable to precode a signal for downlink transmission to each receiver in the set of K receivers based on multi-user MIMO using precoding derived based on two-way channel training between the set of K receivers and the set of N transmit antennas.
