Abstract

Provided are a signal transmission method, terminal and network equipment, the method comprising: a terminal receiving first information sent by a network equipment, the first information being used for indicating that a first SRS resource is used for multiple purposes; and the terminal sends the SRS corresponding to the first SRS resource to the network equipment according to the first information. According to the invention, the network equipment can control the terminal to send the first SRS resource based on multiple purposes, so that the reuse of the purposes of the SRS resource is realized, and the SRS transmission overhead can be reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a signal transmission method, terminal and network equipment. Background technique [0002] SRS (Sounding Reference Signal, channel sounding reference signal) is an uplink reference signal, which can be used for channel quality estimation (for measuring CSI (Channel State Information, channel state information)) and beam management. UE (User Equipment, user equipment) sends SRS to network equipment, and after network equipment receives SRS sent by UE, it can perform PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) scheduling, downlink scheduling, and uplink beam management based on SRS measurement Wait. The base station can configure SRS resources for the UE, and configure a corresponding use for each SRS resource. Based on the SRS corresponding to the SRS resource has a corresponding use, the UE can send the SRS corresponding to the SRS r...
