Abstract
A technique for efficiently transmitting and receiving a downlink reference signal in a single user mode or a multiuser mode is disclosed. In the case of transmitting the downlink data demodulation reference signal (DMRS) using two or more layers, the DMRS of each layer can be multiplexed by the code division multiplexing (CDM) method and transmitted. The DMRS of each of the two or more layers may be for one user equipment (UE) or for two or more UEs, and the downlink control signal for such DMRS transmission / reception may be a single user mode (SU-MIMO) Mode (MU-MIMO).
