RADIO COMMUNICATION SYSTEM, BASE STATION APPARATUS, TERMINAL APPARATUS, AND RADIO COMMUNICATION METHOD IN RADIO COMMUNICATION SYSTEM

摘要

A radio communication system (10) comprising a first transmitter (100-1) and one or more second transmitters (100-2) which include one or more of cells or sectors respectively, and a receiver (200) configured to perform radio communication with the first transmitter and the one or more second transmitters, wherein the first transmitter includes a control information generation unit (106) configured to transmit information for generating a common scrambling code by the first transmitter and the one or more second transmitters, to the one or more second transmitters, the first transmitter and the one or more second transmitters include a process unit (114) configured to perform a scrambling process to transmission data by using a common scrambling code respectively, when the transmission data in each of the cells or the sectors is transmitted to the receiver respectively; and a transmission unit (115) configured to transmit the scrambled transmission data to the receiver respectively, and the receiver includes a reception unit (202) configured to receive the scrambled transmission data and perform a descrambling process to the scrambled transmission data by using the common scrambling code.
