Problems solved by technology

There is a gap of more than 12dB between the link budget of SRS in the 3.5GHz TDD system and the link budget of the 1.8GHz FDD system, which cannot meet the requirements of co-site and co-coverage between the 1.8GHz FDD system and the 3.5GHz TDD system. The performance of 3.5GHz TDD system will be seriously affected

Abstract

A method for processing a sounding reference signal, a base station and a user equipment. The method for processing a sounding reference signal comprises: configuring indication information used for indicating N symbols in a uplink pilot time slot (UpPTS) in a special subframe, wherein the N symbols are used for carrying an SRS repeatedly sent by a first user equipment (UE), the special subframe comprises: a downlink pilot time slot (DwPTS), a guard period (GP) and the UpPTS, and N is a natural number greater than 2; sending the indication information, the configuration thereof being complete, to the first UE; and receiving, on the N symbols in the UpPTS in the special subframe, the SRS sent by the first UE.

Description

Technical field[0001]Embodiments of the present invention relate to the field of communications, and more particularly to processing methods and base stations and user equipment for detecting reference signals.Background technique[0002]In the current advanced long-term evolution (LTE-A) system, the Evolved Node B, ENBs requires a wireless communication channel quality of the User Equipment, UE. Therefore, the UE transmits the uplink detection reference signal (SOUNDING REFERENAL, SRS) to the eNB, and the eNB estimates the upstream channel quality of each UE in different frequency bands by receiving and detecting the SRS, thereby estimating the Quality Resource block (Physical Resource Block). , PRB) allocation, modulation coding method, multi-antenna transmission parameter setting, etc. Provide a reference basis. The detection of SRS has an important impact on the performance of the wireless communication system, especially in the multi-antenna communication system, and the accuracy...
