Abstract
(EN) In order to prevent a drop in communication throughput and the like even where multiplexing is supported for uplink control information on an uplink data channel, an embodiment of a base station disclosed herein has: a transmission unit for transmitting download data and downlink control information instructing an upload transmission; and a control unit for controlling scheduling such that the number of bits of a delivery acknowledgement signal of the download data, which is to be multiplexed on a first uplink shared channel where transmission is on the basis of the downlink control information and/or a second uplink shared channel where transmission is independent of the downlink control information, is at most a predefined value.
(FR) Afin d'empêcher une baisse du débit de communication, et analogue, même lorsqu'un multiplexage est pris en charge en ce qui concerne des informations de commande de liaison montante sur un canal de données de liaison montante, la présente invention, selon un mode de réalisation, concerne une station de base comprenant : une unité de transmission servant à transmettre des données de téléchargement aval et des informations de commande de liaison descendante ordonnant une transmission de téléchargement amont ; et une unité de commande servant à commander une planification de sorte que le nombre de bits d'un signal d'accusé de réception de délivrance des données de téléchargement aval, qui doit être multiplexé sur un premier canal partagé de liaison montante sur lequel une transmission est basée sur les informations de commande de liaison descendante et/ou sur un second canal partagé de liaison montante sur lequel une transmission est indépendante des informations de commande de liaison descendante, soit au plus une valeur prédéfinie.
(JA) 上りデータチャネルに対する上り制御情報の多重がサポートされる場合であっても通信スループットなどの低下を抑制するために、本開示の基地局の一態様は、UL送信を指示する下り制御情報及びDLデータを送信する送信部と、前記下り制御情報に基づいて送信される第1の上り共有チャネル及び/又は前記下り制御情報によらずに送信される第2の上り共有チャネルに多重される前記DLデータの送達確認信号のビット数が所定値以下となるようにスケジューリングを制御する制御部と、を有する。
