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

摘要

A radio communication system including: a first and second base station apparatuses which include one or more of sells or sectors respectively; and a terminal apparatus, wherein the first and second base station apparatuses and the terminal apparatus performs radio communication, the first and second base station apparatuses includes: a process unit which performs a scrambling process to a first and second transmission data respectively by using a common scrambling code when the first and second transmission data differing each of the cells or the sectors are transmitted to the terminal apparatus; and a transmission unit which transmits the scrambling processed first and second transmission data to the terminal apparatus respectively, and the terminal apparatus includes a reception unit which receives the first and the second transmission data and performs descrambling process to the first and the second transmission data by using the common scrambling code.
