Abstract  Abstract

Techniques for transmitting data from a transmitter unit to a receiver unit in a multiple-input multiple-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 each receive antenna comprising a combination of one or more signals transmitted from the transmitter unit. The received signals are processed with a spatial a space-time or a full-CSI technique to derive channel state information (CSI) indicative of the characteristics of a number of transmission channels used for data transmission. The CSI (which may comprise SNR estimates data rate indicators complex channel gains or some other information) is transmitted back to the transmitter unit. At the transmitter unit the CSI is received and data for transmission to the receiver unit is processed (e.g. coded and modulated) based on the received CSI.
