Abstract: front page image
(EN)In a case where wireless communications are performed between a plurality of base station apparatuses and a terminal apparatus, the constraints are reduced which result from the generation of the identifying code of a reference signal used in a cooperative reception and from the placement of the reference signal.  Terminal apparatuses (UE201-UE205), which exist within the cell of a base station apparatus (BS200), currently communicate with the base station apparatus (BS200).  When a terminal apparatus (UE201) is located at an edge of the cell and its reception characteristic is degraded, another base station apparatus (specifically, base station apparatus BS100) performs cooperative transmissions together with the base station apparatus (BS200), and the terminal apparatus (UE201) performs cooperative receptions.  At this moment, in demodulating signals from the base station apparatus (BS100), the terminal apparatus (UE201) uses, as the identifying code of a reference signal that is transmitted from the base station apparatus (BS100) and specific to the terminal apparatus, the identifying code of a reference signal that is different from a reference signal used in demodulating signals from a single base station.
(FR)
(JA) 複数の基地局装置と、端末装置との間で無線通信を行う場合、協調受信に使用する参照信号の識別符号の生成および参照信号の配置から来る制約を低減することができるようにする。  端末装置UE201から端末装置UE205は、基地局装置BS200のセル圏内に存在する端末装置であり、基地局装置UE200と通信を行っている。端末装置UE201がセル端に位置し、受信特性が劣化する場合には、他の基地局装置、具体的には基地局装置BS100からも協調送信を行い、端末装置UE201は協調受信を行う。このとき、基地局装置BS100からの信号の復調には基地局装置BS100から送信される端末装置固有の参照信号の識別符号は、端末装置が単一の基地局からの信号を復調する際に用いる参照信号とは異なる参照信号の識別符号を用いる。
