Abstract
A reference signal transmission method is provided, including: generating, by a network side device, a transmission unit, where the transmission unit includes a user equipment-specific demodulation reference signal UE-specific DM-RS, a time-frequency region for unicast control, and a user-specific data time-frequency region; and sending the transmission unit to user equipment, where the UE-specific DM-RS is reused or shared to demodulate the time-frequency region for unicast control and the user-specific data time-frequency region.
