Abstract:
(EN) Provided is a communication apparatus that facilitates low delay during retransmission control in a wireless communication system. The communication apparatus is for carrying out retransmission without using ACK/NACK, and is provided with: a signal generation unit that generates a transmission signal and a retransmission signal for the transmission signal; a control unit that performs scheduling of the transmission signal and the retransmission signal; and a transmission unit that transmits the transmission signal and the retransmission signal, wherein the control unit performs the scheduling such that the retransmission signal is transmitted at least one symbol after the transmission signal.
(FR) L'invention concerne un appareil de communication qui permet un faible retard pendant une commande de réémission dans un système de communication sans fil. L'appareil de communication est destiné à effectuer une réémission sans faire appel à un ACK/NACK, et comporte : une unité de génération de signal qui génère un signal d'émission et un signal de réémission pour le signal d'émission ; une unité de commande qui effectue une programmation du signal d'émission et du signal de réémission ; et une unité d'émission qui émet le signal d'émission et le signal de réémission. L'unité de commande effectue la programmation de telle sorte que le signal de réémission est émis au moins un symbole après le signal d'émission.
(JA) 無線通信システムにおける再送制御において、低遅延化を図る通信装置を提供する。ACK/NACKを用いずに再送信を行う通信装置であって、送信信号と、送信信号の再送信号とを生成する信号生成部と、送信信号および再送信号のスケジューリングを行う制御部と、送信信号および再送信号を送信する送信部と、を備え、制御部は、再送信号が送信信号に対し、少なくとも1シンボルあけて送信されるようにスケジューリングを行う。
