Signal processing method and device for cell merging scene, network side and storage medium

Abstract

The embodiment of the invention provides a signal processing method and device for a cell merging scene, a network side and a storage medium, and the method comprises the steps: determining a plurality of RRUs (radio remote units) corresponding to a terminal from all RRUs based on signals sent by the terminal and received by all RRUs of merged cells, wherein the coverage ranges of the plurality of RRUs corresponding to the terminal each comprise the position of the terminal; and on the basis of the plurality of RRUs corresponding to the terminal, performing uplink receiving and / or downlink sending of signals on the terminal. According to the method, the device, the network side and the storage medium provided by the embodiment of the invention, the problems that the cell capacity is reduced and the signal receiving and sending cannot be normally carried out due to the joint receiving and sending by all RRUs in the merged cell are avoided, the signal receiving and sending are carried out only in the coverage ranges of the plurality of RRUs corresponding to the terminal, the signal quality of uplink and downlink signals can be effectively improved, and multi-user multiplexing can be supported, so that the system capacity is further improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a signal processing method, device, network side and storage medium of a cell merging scenario. Background technique [0002] Cell merging refers to connecting multiple single-channel or multi-channel RRUs (Remote Radio Units, remote radio units) to the same BBU (Base band Unit, baseband processing unit) and setting them as the same logical cell. [0003] In the cell merging scenario, for the network side, all RRUs in the merged cell belong to the same logical cell. In the prior art, all RRUs in the merged cell are regarded as multiple antennas for uplink reception and downlink transmission. However, different RRUs in the merged cell have different antenna configurations. Joint reception or transmission based on RRUs with different antenna configurations on the network side will reduce the capacity of the merged cell, and the total number of antennas of...
