Title (EN) WIRELESS COMMUNICATION TERMINAL DEVICE AND METHOD OF SIGNAL DIFFUSION
(FR) DISPOSITIF TERMINAL DE COMMUNICATION SANS FIL ET PROCÉDÉ DE DIFFUSION DE SIGNAUX
(JA) 無線通信端末装置および信号拡散方法
Abstract:
(EN) Disclosed is a wireless communication terminal device that is capable of preventing inter-coding interference upon each of a plurality of base stations, even when the timing changes for a transmission of a control signal that is CoMP received by the plurality of base stations. Upon the device, a diffusion unit (214) employs any of a plurality of ZAC series that are reciprocally splittable with a reciprocally variable cyclical shift quantity to diffuse a response signal, according to an instruction from a control unit (209), and the control unit (209) controls, according to a difference between a timing of a transmission of a response signal at a first time and a timing of a transmission of a response signal at a second time that is later than the first time, the cyclical shift quantity of the ZAC series that is employed by the diffusion unit (214) at the second time.
(FR) La présente invention a pour objet un dispositif terminal de communication sans fil qui peut empêcher le brouillage intercodage sur chaque station de base d'une pluralité de stations de base, même lorsqu'il se produit un changement dans la synchronisation de la transmission d'un signal de commande que la pluralité de stations de base reçoit par CoMP. Sur le dispositif, une unité de diffusion (214) utilise une séquence ZAC appartenant à une pluralité de séquences ZAC réciproquement divisibles avec une quantité de décalage circulaire variable réciproquement afin de diffuser un signal de réponse, conformément à une instruction provenant d'une unité de commande (209), et cette unité de commande (209) contrôle, en fonction de la différence entre la synchronisation de la transmission d'un signal de réponse à un premier moment et la synchronisation de la transmission d'un signal de réponse à un second moment ultérieur par rapport au premier, la quantité de décalage circulaire de la séquence ZAC utilisée par l'unité de diffusion (214) au second moment.
(JA)  複数の基地局でCoMP受信される制御信号の送信タイミングが変化する場合でも、各基地局での符号間干渉を防止することができる無線通信端末装置。この装置において、拡散部(214)は、制御部(209)からの指示に従って、互いに異なる循環シフト量により互いに分離可能な複数のZAC系列のいずれかを用いて、応答信号を拡散し、制御部(209)は、第1時刻における応答信号の送信タイミングと、第1時刻より後の第2時刻における応答信号の送信タイミングとの差分に応じて、第2時刻において拡散部(214)で用いられるZAC系列の循環シフト量を制御する。
