Method of transmitting control information using physical uplink shared channel region in mimo antenna system

Abstract

Provided is a method of transmitting control information using a physical uplink shared channel (PUSCH) region in a system employing a multi-input multi-output (MIMO) antenna system in which transmission is performed through a plurality of layers. A method of transmitting a channel quality indicator (CQI)/precoding matrix indicator (PMI) using a PUSCH region in a system employing a MIMO antenna system in which transmission is performed through a plurality of layers includes encoding the CQI/PMI using one channel encoder, and transmitting the encoded CQI/PMI using some or all of the layers. Accordingly, it is possible to transmit uplink control information through a PUSCH region using a plurality of layers.

We claim: 
     
         1 . A method of transmitting control information to a base station, the method comprising:
 encoding the control information;   separating the encoded control information into N parts; and   transmitting the N parts of control information using N layers.   
     
     
         2 . The method of  claim 1 , wherein the control information comprises channel quality indicator (CQI), precoding matrix indicator (PMI) and ACK/NACK and rank indicator (RI). 
     
     
         3 . The method of  claim 1 , wherein the N layers are all layers mapped to a same codeword when the control information is CQI/PMI. 
     
     
         4 . The method of  claim 1 , wherein the N is a positive integer greater than 1, and the control information is transmitted through an uplink shared channel.
