METHOD AND SYSTEM FOR SENDING SRS

摘要

Disclosed are a method and system for sending a sounding reference signal (SRS). The method includes: user equipment (UE) sending an SRS to a base station on a time domain resource, frequency domain resource and/or code domain resource; wherein the time domain resource includes: the last time domain symbol, the first time domain symbol or the second last time domain symbol of a subframe where an SRS period is located; the frequency domain resource includes: the frequency domain location or a sending frequency comb of the SRS; and the code domain resource is obtained by the following ways: the UE generating a sequence group number of the SRS according to a user specific parameter configured for the UE by the base station by way of high-layer signalling, and determining the code domain resource required for sending the SRS according to the generated sequence group number of the SRS. The present invention can increase the available resources of the SRS, improve the user multiplexing capacity of the SRS, and enhance the channel estimation quality of the SRS by a base station, thus supporting the application of the coordinated multi-point transmission and reception (CoMP) system more effectively.
