Abstract
The present disclosure provides a method and device for transmitting a reference signal, a method and device for receiving the same, the transmitting method includes: determining a first antenna port for transmitting a demodulation reference signal and a second antenna port for transmitting an enhanced reference signal, where the second antenna port and the first antenna port have an association; setting a transmitting power for the demodulation reference signal and a transmitting power for the enhanced reference signal; transmitting the demodulation reference signal and the enhanced reference signal to a terminal based on the first antenna port being determined for transmitting the demodulation reference signal and the second antenna port being determined for transmitting the enhanced reference signal, and according to the transmitting powers being set. Accordingly, when present technical solution is applied, a channel estimation performance and a RRM measurement performance of a NB-IOT terminal can be effectively improved.
