Abstract

The present application relates to the technical field of wireless communication, and in particular to a method for transmitting sounding reference information SRS, which can solve the problem of when to transmit the SRS. In this method, the user equipment UE receives the SRS resource configuration information sent by the base station; the UE receives the downlink control information DCI sent by the base station; the UE sends the SRS on a determined time slot and symbol, and the determined symbol is the The UE determines based on the SRS resource configuration information.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for configuring a Sounding Reference Signal (SRS) in a wireless communication system. Background technique [0002] Currently, a user equipment (User Equipment, UE) implements uplink measurement by sending a sounding reference signal (Sounding Reference Signal, SRS), and a base station measures the received SRS to obtain uplink channel state information. [0003] After the base station configures time resources, frequency resources and code domain resources for SRS transmission, the UE can perform SRS transmission on the resources configured by the base station, and the base station obtains uplink channel state information after receiving the SRS. [0004] After the UE receives the configuration information about the SRS sent by the base station, when to transmit the SRS is a problem that needs to be solved. Contents of the inven...
