Abstract

The invention relates to the technical field of communication, and aims to provide an RRU data merging method and system for a base station and a processing device. The RRU data merging system comprises a data acquisition unit which is used for acquiring the mapping relation between all RHUBs and RRUs, the mapping relation between UE and the RRUs and uplink scheduling information of all UE with uplink scheduling data in one uplink scheduling; a database; an RRU screening unit which is used for obtaining all RRUs related to the specified UE from a database for screening and selecting the optimal RRU; a data extraction unit for acquiring time-frequency data corresponding to the uplink scheduling information of the UE in the data of the optimal RRU, extracting the data of the corresponding time frequency of the optimal RRU as the uplink scheduling data of the specified UE, and sending the uplink scheduling data of the specified UE to the RHUB having the mapping relation with the optimal RRU according to the mapping relation between all the RHUBs and the RRU, wherein the RHUB transmits the uplink scheduling data of the specified UE to the BBU. The method has the advantages that 3dB demodulation performance loss is reduced, and the demodulation performance of the base station side is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and processing device for combining RRU data of a base station. Background technique [0002] to combine figure 1 , in the deployment of 5G base stations, the remote radio unit (RRU) deployment scheme based on multiple rHUBs and the remote radio unit (RRU) deployment scheme of multi-level rHUB cascading will be adopted. Under these two deployment schemes, for the BBU In other words, there are multiple remote radio units (RRUs) on each rHUB connected to it, and the uplink signal received by each RRU will eventually be converged to the BBU. If no optimization is performed, it will be converged to the BBU The amount of uplink signal data will be very large, and the transmission will not be able to bear such a huge amount of transmission data. Therefore, it is necessary to merge the aggregated RRU uplink signals on a certain level of rHUB to form a si...
