Title (EN) COMMUNICATIONS SYSTEM
(FR) SYSTÈME DE COMMUNICATION
(JA) 通信システム
Abstract:
(EN) Provided is a communication system with which it is possible to suppress a reduction in transmission speed. An eNB and a UE communicate using a self-contained subframe. The self-contained subframe includes a downstream signal transmitted from the eNB to the UE and an upstream signal transmitted from the UE to the eNB in response to the downstream signal. The upstream signal is composed by including an upstream control signal that represents information to control the transmission of the upstream signal and upstream user data that is transmitted before and after the upstream control signal. The eNB notifies the UE about the composition of the upstream signal. The eNB may predetermine scheduling for retransmission for retransmitting a downstream signal before initially transmitting the downstream signal.
(FR) L'invention concerne un système de communication avec lequel il est possible de supprimer une réduction de la vitesse de transmission. Un eNB et un UE communiquent au moyen d'une sous-trame autonome. La sous-trame autonome comprend un signal aval transmis de l'eNB à l'UE et un signal amont transmis de l'UE à l'eNB en réponse au signal aval. Le signal amont est composé en incluant un signal de commande amont qui représente des informations pour commander la transmission du signal amont et des données d'utilisateur amont qui sont transmises avant et après le signal de commande amont. L'eNB notifie à l'UE la composition du signal amont. L'eNB peut prédéfinir la planification de retransmission pour retransmettre un signal aval avant de transmettre initialement le signal aval.
(JA) 伝送速度の低下を抑えることができる通信システムを提供する。eNBとUEとは、自己完結型サブフレームを用いて通信する。自己完結型サブフレームは、eNBからUEに送信される下り信号と、下り信号に応答してUEからeNBに送信される上り信号とを含む。上り信号は、上り信号の送信を制御する情報を表す上り制御信号と、上り制御信号の前後に送信される上りユーザデータとを含んで構成される。eNBは、UEに、上り信号の構成を通知する。eNBは、下り信号を再送するための再送用のスケジューリングを、下り信号の初送を行う前に、予め決定しておいてもよい。
