摘要： The present invention is to enable reduction of constraint brought by generation of ID codes of reference signals to be used for cooperative reception and the allocation of the reference signals when radio communication is carried out between a plurality of base station apparatuses and a terminal unit.Terminal units UE201 to UE205 are terminal units existing in the cellular zone of a base station apparatus BS200 and are performing communication with base station apparatus UE200. When terminal unit UE201 is located at the edge of cell and its reception characteristic degrades, another base station apparatus, specifically, base station apparatus BS100 also performs cooperative transmission while terminal unit UE201 performs cooperative reception. In this case, in order to demodulate the signal from base station apparatus BS100, an ID code of a reference signal that is different from the reference signal the terminal unit uses to demodulate the signal from a solo base station apparatus is used as the ID code of the reference signal that is transmitted from base station apparatus BS100 and specific to the terminal unit.
摘要翻译：本发明是为了能够减少在多个基站装置与终端装置之间进行无线通信时，通过生成用于协作接收的参照信号的ID代码和参照信号的分配而产生的约束。终端单元UE201〜UE205是存在于基站装置BS200的蜂窝区域中的终端单元，并且正在与基站装置UE200进行通信。当终端单元UE201位于小区的边缘并且其接收特性劣化时，另一个基站装置，具体地，基站装置BS100，在终端单元UE201进行协作接收的同时也进行协作发送。在这种情况下，为了解调来自基站装置BS100的信号，使用与终端单元用于解调来自独立基站装置的信号的参考信号不同的参考信号的ID码作为ID代码从基站装置BS100发送的基站信号和特定于终端装置的基准信号。

摘要： A reference signal specific to each base station device and a reference signal specific to each mobile station device are not mixed within one OFDM symbol of a resource block, and OFDM symbols including the reference signal specific to each mobile station device are arranged at regular intervals on a time axis. By using such a signal arrangement pattern, it is possible to overcome the problems in Non-Patent Document 1 mentioned above caused by mixing a reference signal specific to each base station device and a reference signal specific to each mobile station device in one OFDM symbol. Thus, it becomes possible to prevent the reference signal specific to each base station device and the reference signal specific to each mobile station device from being mixed within one OFDM symbol of a resource block.
