摘要： Even when a same C-RNTI is allocated to multiple mobile stations in a phantom cell, a collision between the mobile stations UE to which the same C-RNTI is allocated is avoided. A radio base station PhNB#10 according to the present invention is configured to manage a cell #10 (phantom cell) which is formed by linking multiple small cells and includes an allocation unit 11 configured to allocate a same C-RNTI ph to multiple mobile stations UE#1/UE#3 which are separated by at least a predetermined distance in the cell #10.
