Title:
SRS TRANSMISSION METHOD AND APPARATUS, AND NETWORK DEVICE, TERMINAL AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/088480
Kind Code:
A1
Abstract:
Provided are an SRS transmission method and apparatus, and a network device, a terminal and a storage medium. The SRS transmission method comprises: 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 an SRS signal sent by the terminal on the basis of the SRS configuration information. By means of the method and apparatus, the network device, the terminal and the storage medium provided in the embodiments in the present disclosure, SRS configuration information is determined on the basis of uplink-related information, and the dynamic configuration of SRS-related parameters is realized, such that the related configuration of an 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.
