Abstract
A method and an apparatus are provided for operating a cascaded base station. Downlink data is received from a plurality of sub-base stations, each of the plurality of sub-base stations having at least one sector, and each of the at least one sector using at least one Frequency Allocation (FA). Data is extracted per FA from the downlink data. The data per sector is rearranged and re-mapped. The data per sector is transmitted to corresponding Remote Radio Units (RRUs).
Claims16
A cascaded base station apparatus comprising:
- a plurality of sub-base stations, each of the plurality of sub-base stations having at least one sector, and each of the at least one sector using at least one Frequency Assignment (FA);
- a plurality of Remote Radio Units (RRUs), each of the plurality of RRUs being responsible for radio communication in a certain sector;
- and
- a radio resource expansion device that receives downlink data from the plurality of sub-base stations, extracts data per FA from the downlink data, rearranges and re-maps the data per sector, and transmits the data per sector to corresponding RRUs.
