Abstract

The embodiment of the invention discloses a transmission method, device and system of a reference signal, and belongs to the technical field of the wireless communication. The method comprises the following steps: receiving a physical layer signaling sent by network equipment, wherein the physical layer signaling comprises configuration information, the configuration information is used for indicating a time domain resource of a reference signal; determining the time domain resource of the reference signal according to the configuration information; sending the reference signal and a first physical channel to the network equipment, wherein the reference signal is used for demodulating the first physical channel. By adopting the invention, the flexibility for configuring the reference signal can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and system for transmitting a reference signal. Background technique [0002] For uplink transmission, the terminal device sends an uplink physical channel and an uplink reference signal to the network device. After receiving it, the network device performs channel estimation according to the uplink reference signal, and then demodulates the uplink physical channel according to the estimated channel value. Conversely, for downlink transmission, the terminal device receives the downlink physical channel and the downlink reference signal sent by the network device, performs channel estimation according to the downlink reference signal, and then demodulates the downlink physical channel according to the estimated channel value. [0003] In the existing system, the uplink / downlink reference signal and the uplink / downlink physical channel are lo...
