WIRELESS BASE STATION APPARATUS, WIRELESS APPARATUS, METHOD FOR RELIEVING LINK DISCONNECTION IN WIRELESS BASE STATION APPARATUS

摘要

A wireless base station apparatus including a wireless control unit, wireless apparatus units, and inter wireless apparatus unit IQ switch. The wireless control unit combines the IQ data sets for different antenna carriers into one combined IQ data set and transmits it to one wireless control unit through the CPRI link. The wireless control unit generates mapping information on the combined IQ data set and transmits it to all the wireless apparatus units. The wireless apparatus unit receives the combined IQ data set and the mapping information through the CPRI link. The wireless apparatus unit divides the combined data set into the IQ data sets for the antenna carriers and transmits the IQ data sets addressed to the unit itself and the other wireless apparatus units according to the mapping information. The inter wireless apparatus unit IQ switch receives the IQ data sets addressed to the other wireless apparatus units from the wireless apparatus unit and transfers the IQ data sets to the corresponding other wireless apparatus units.
