摘要： A technique for receiving and transmitting downlink reference signals is disclosed. When transmitting downlink data demodulation reference signals (DMRS) (or reference signals for downlink data demodulation) by using two or more layers, the DMRS of each layer may be multiplexed by using a code division multiplexing method and then transmitted. The DMRS for each of the two or more layers may be used for one user equipment or for two or more user equipments. And, downlink control signals for transmitting and receiving such DMRS may be configured to have the same format regardless of a single-user mode (or SU-MIMO mode) or a multi-user mode (or MU-MIMO mode), thereby being used.

摘要： The present invention relates to a channel quality information transmission method in a communication system adopting a coordinated multi-point scheme. A terminal receives signals, through the same band, from a serving base station and at least one neighbor base station, respectively, which are included in a CoMP set operating in a joint processing mode. Next, the terminal generates combined channel quality information on a single signal obtained by combining the signals received through the same band, and then transmits the information to the serving base station. The combined channel quality information is generated using information on a combined channel obtained by combining channels between the terminal and the serving base station and between the terminal and each one of the at least one neighbor base station, which are included in the CoMP set.
