Radio communication system, base station apparatus, terminal apparatus, and radio communication method in radio communication system

A radio communication method in a radio communication system for performing radio communication between a first and second transmitters which include one or more of cells or sectors, and a receiver, the method comprising:

• performing a scrambling process to a first transmission data by using a common scrambling code when the first transmission data is transmitted to the receiver, by the first transmitter;
• transmitting the scrambling processed first transmission data to the receiver, by the first transmitter;
• performing a scrambling process to a second transmission data by using the common scrambling code when the second transmission data is transmitted to the receiver, by the second transmitter;
• transmitting the scrambling processed second transmission data to the receiver, by the second transmitter;
• and
• receiving the first and second transmission data and performing descrambling process to the first and second transmission data by using the common scrambling code, by the receiver.
