and the data extraction unit is used for acquiring time-frequency data corresponding to the UE uplink scheduling information in the data of the optimal RRU, extracting the time-frequency data corresponding to the optimal RRU as the uplink scheduling data of the designated UE, taking the designated UE, the designated frequency domain and time domain data of the optimal RRU under the designated RHUB as the unique uplink scheduling data of the designated UE on the RHUB according to the mapping relation between all the RHUBs and the RRUs, and sending the data to the previous-stage RHUB or BBU.
9. The system of claim 8, wherein the database comprises a database comprising RRU data for a base station
The RHUB and RRU mapping table is used for caching mapping relations between all RHUBs and RRUs;
the mapping table of the UE and the RRU is used for caching mapping relations between all the UE and the RRU;
and the TTI level UE uplink scheduling mapping table is used for caching uplink scheduling information corresponding to the UE with uplink scheduling data in each scheduling period TTI.
10. A processing apparatus for RRU data combining for a base station, comprising a processor, a memory and a computer program stored on the memory and operable on the processor, which when executed by the processor implements the steps of a method for RRU data combining for a base station according to any of claims 1 to 7.
