Abstract  Abstract

to data transmitting technology of the receiver unit from the transmitter unit in a multiple-input multiple-output (MIMO) communication system. In one method a plurality of signals are received via a plurality of receiving antennas and the signal received from the transmitter unit. characteristic of many transmission channels to the received signal is processed to derive channel state information (CSI) which is indicated for the data transmission. CSI is transmitted back to the transmitter unit. the transmitter unit the CSI from the receiver unit is received and transmitted to the receiver unit data is processed according to the received CSI.

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 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.
