Abstract

The present application relates to an SRS transmission method, device, equipment, system and storage medium. The base station allocates the period information of the corresponding uplink SRS symbol to be extracted and the downlink time slot parameters for each remote radio unit, so that each remote radio unit extracts the SRS symbol and inserts the SRS symbol into the corresponding downlink subframe, and then The SRS can be transmitted back to the base station through the corresponding downlink time slot; each radio remote unit corresponds to each downlink time slot parameter one by one. Based on this, when multiple remote radio units RRU receive the SRS symbols of the uplink time slot at the same time, they can move their respective SRS symbols to the corresponding downlink time slots and rearrange them, and then send them back to the base station for analysis; each remote radio unit uses The corresponding downlink time slots transmit SRS symbols back and forth, so that the base station can distinguish the source of SRS, solve the problem of signal distortion caused by SRS superposition on multiple remote radio units, and achieve the base station's uplink channel of each remote radio unit Quality is performed for precise performance evaluation and control purposes respectively.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to an SRS transmission method, apparatus, device, system and storage medium. Background technique [0002] In a TDD-LTE system, a user equipment (User Equipment, UE) usually sends a sounding reference signal (Sounding Reference Signal, SRS) to a base station (eNodeB) according to a network configuration. The base station can perform operations such as uplink channel quality estimation, uplink frequency selective scheduling, uplink timing estimation, and closed-loop power control by analyzing the received SRS. [0003] However, in a new indoor distribution system, a cell is cooperatively covered by multiple remote radio units (Remote Radio Units, RRUs) to increase the coverage area of ​​the cell. There will be overlapping areas between multiple remote radio units, so the uplink signal of the UE will be superimposed by multiple different remote radio units and...
