Reference signal transmitting method and apparatus

Abstract

Embodiments of the present disclosure provide a reference signal transmitting method and apparatus. The method includes: reference signal parameters are received, the reference signal parameters at least include the number P of ports of a reference signal and a modulation and coding scheme of the reference signal, and the number P of ports of the reference signal is determined according to the modulation and coding scheme; and the reference signal is received according to the reference signal parameters. The problem that in the related technologies, channel estimation is performed through demodulation reference signals, and when transmitted modulation information is demodulated on an estimated channel, there is an excessive demodulation reference signal overhead can be solved.
