Abstract
A method for efficiently transmitting and receiving a downlink reference signal in a single user mode or a multiple user mode is disclosed. When transmitting a reference signal (DMRS) for demodulating downlink data using two or more layers, the DMRS of each layer can be multiplexed and transmitted by a code division multiplexing (CDM) method. Each DMRS of two or more layers may be for one user equipment (UE) or may be for two or more UEs. Such downlink control signals for DMRS transmission / reception can be used in the same format regardless of the single user mode (SU-MIMO) / multiple user mode (MU-MIMO). (Selection) Figure 5
