Title (EN) RADIO COMMUNICATION DEVICE AND BANDWIDTH DETERMINATION METHOD
(FR) DISPOSITIF DE RADIOCOMMUNICATION ET PROCÉDÉ DE DÉTERMINATION DE BANDE PASSANTE
(JA) 無線通信装置および帯域幅決定方法
Abstract: front page image
(EN)Disclosed is a radio communication device that, even when a terminal erroneously receives a retransmission grant or a response signal from a base station, can reduce the number of other terminals in which the terminal interferes at a retransmission. In this device, a determination unit (205) determines a bandwidth between the two ends of a transmission band allocated to a transmitted signal at the retransmission of the transmitted signal. An allocation unit (209) allocates the transmitted signal to a frequency resource based on the bandwidth that is input from the determination unit (205). The determination unit (205) increases at the retransmission the amount of decrease in the bandwidth from the previous transmission, as the consecutiveness of the transmitted signal in the frequency region decreases.
(FR)L'invention porte sur un dispositif de radiocommunication qui, même lorsqu'un terminal reçoit de façon erronée un accord de retransmission ou un signal de réponse provenant d'une station de base, peut réduire le nombre d'autres terminaux dans lesquels le terminal interfère au niveau d'une retransmission. Dans ce dispositif, une unité de détermination (205) détermine une bande passante entre les deux extrémités d'une bande de transmission allouée à un signal transmis au niveau de la retransmission du signal transmis. Une unité d'allocation (209) alloue le signal transmis à une ressource de fréquence sur la base de la bande passante qui est entrée à partir de l'unité de détermination (205). L'unité de détermination (205) augmente à la retransmission la quantité de diminution de bande passante par rapport à la transmission précédente, à mesure que le caractère consécutif du signal transmis dans la région de fréquence diminue.
(JA) 端末が基地局からの再送Grantまたは応答信号の受信を誤ってしまう場合でも、端末が再送時に干渉を与える他の端末の数を低減することができる無線通信装置。この装置において、決定部(205)は、送信信号の再送時にその送信信号に割り当てられる送信帯域の両端間の帯域幅を決定し、割当部(209)は、決定部(205)から入力される帯域幅に基づいて、送信信号を周波数リソースに割り当てる。決定部(205)は、送信信号の周波数領域での連続度が低いほど、前回送信時に対する再送時の帯域幅の減少量をより大きくする。
