Abstract

The embodiment of the invention discloses an SRS transmission method, a terminal device and a network device, which are used to solve the problem of poor flexibility of SRS resource configuration in the prior art. The method includes: receiving DCI, the DCI includes a resource indication field, the resource indication field includes at least one of a frequency domain resource indication field and a time domain resource indication field, and the frequency domain resource indication field is used to indicate the SRS The frequency domain resources occupied by sending, the time domain resource indication field is used to indicate the time domain resources occupied by the SRS transmission; determine the resources occupied by the SRS transmission based on the resource indication field; send the SRS.

Description

technical field [0001] The present application relates to the communication field, and in particular to a sounding reference signal (Sounding Reference Signal, SRS) transmission method, terminal equipment and network equipment. Background technique [0002] In existing mobile communication systems, resources occupied by SRS are configured through Radio Resource Control (RRC) signaling. However, high-level signaling reconfiguration will cause a large delay, resulting in the flexibility of SRS resource configuration. poor. Therefore, in order to enhance the coverage performance and capacity of SRS and improve the performance of SRS channel estimation, it is necessary to support a more flexible SRS resource allocation scheme. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an SRS transmission method, a terminal device and a network device, so as to solve the problem of poor flexibility of SRS resource configuration in ...
