METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING CONTROL INFORMATION OF MIMO SYSTEM

摘要

The present invention relates to a method and a system for transmitting and receiving control information of an MIMO (Multi-Input Multi-Output) system, wherein the control information consists of information bits and parity bits. A base station transmits the control information including the location information for where the control information of the other terminal is transmitted. A terminal receives the control information of the other terminal based on the location information for where the control information of the other terminal is received. Therefore, the precoding matrix of the other terminal can be obtained from the received control information. The invention enables the removal of interference through the obtained precoding matrix when receiving a data symbol in an environment where a channel is not in a good state.
