IPC: H04L1/00
Filed: 2002-03-22
Abstract: Techniques for transmitting data from a transmitter unit to a receiver unit in a multiple-input mutiple-output (MIMO) communication system. In one method, at the receiver unit, a number of signals are received via a number of receive antennas, with the received signal from the transmitter unit. The received signals are processed to derive channel state information (CSI) indicative of characteristics of a number of transmission channels used for data transmission. The CSI is transmitted back to the transmitter unit. At the transmitter unit, the CSI from the receiver unit is received and data for transmission to the receiver units is processed based on the received CSI.
