Abstract
Provided are a method and apparatus for transmitting a sounding reference signal (SRS), and a network device, a terminal. The method includes determining SRS configuration information on the basis of uplink related information corresponding to a terminal; issuing the SRS configuration information to the terminal; and receiving a SRS signal sent by the terminal on the basis of the SRS configuration information. By means of the method the network device, the terminal, SRS configuration information is determined on the basis of uplink-related information, and the dynamic configuration of SRS-related parameters is realized, and the related configuration of a SRS can better adapt to rapid changes in a Doppler frequency shift and a transmission delay caused by fast movement of a satellite, an uplink time-frequency estimation can resist fast-changing timing and frequency deviations, and the timeliness requirement of the uplink time-frequency estimation is satisfied.
