Method for transmitting DM-RS for broadcast data in next generation communication system and apparatus therefor

A method for transmitting a downlink signal from an eNB to a user equipment (UE) in a wireless communication system, the method comprising:

• transmitting a downlink control channel to the UE;
• and
• transmitting a downlink data channel corresponding to the downlink control channel and a front loaded reference signal for demodulation of the downlink data channel to the UE,
• wherein the front loaded reference signal has a repetition factor of 2 on a single symbol of an antenna port of a minimum index,
• wherein the downlink control channel is masked with an identifier indicating that the downlink data channel is a broadcast data channel.

A user equipment (UE) in a wireless communication system, the UE comprising:

• a wireless communication module;
• and
• a processor connected with the wireless communication module, receiving a downlink control channel from the eNB, and receiving a downlink data channel and a front loaded reference signal for demodulation of the downlink data channel by using control information included in the downlink control channel,
• wherein the front loaded reference signal has a repetition factor of 2 on a single symbol of an antenna port of a minimum index,
• wherein the downlink control channel is masked with an identifier indicating that the downlink data channel is a broadcast data channel.
