摘要： A method of transmitting data in a wireless communication system includes preparing a frame including a unicast subframe for unicast data and an MBS (Multicast and Broadcast Service) subframe for MBS data; and transmitting the unicast data and the MBS data via the frame, wherein the MBS subframe includes an idle time during which data is not carried, and the idle time is arranged to be at the temporally latest position in the MBS subframe. An MBS frame structure for using an appropriate CP with respect to MBS signals transmitted from multi-cell is provided, so an unnecessary idle time can be reduced, and thus, the efficiency of limited radio resources can be improved.

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.
