WIRELESS BASE STATION AND MOBILE STATION

摘要

An objective of the present invention is to prevent collision between mobile stations to which the same C-RNTI is allocated in a simple implementation while avoiding a problem of C-RNTI depletion in a phantom cell. A radio base station eNB of the present invention includes an allocation unit 11 configured to allocate multiple C-RNTIs to each of mobile stations UE#1 to UE#4, and the allocation unit 11 performs adjustment such that collision of search spaces to which PDCCH resources are allocated does not occur among the multiple mobile stations UE#1 to UE#4.
