Title (EN) APPARATUS AND SYSTEM RELATED TO WIRELESS ACCESS NETWORK
(FR) APPAREIL ET SYSTÈME LIÉS À UN RÉSEAU D'ACCÈS SANS FIL
(JA) 無線アクセスネットワークに関連する装置及びシステム
Abstract:
(EN) [Problem] To enable further reduction of amount of information to be transmitted from one of two nodes, bearing the processings of a wireless access network in common, to the other. [Solution] An apparatus of the invention comprises: an information generation unit that performs, on the basis of an uplink signal transmitted by a terminal apparatus, a channel estimation, thereby generating channel information about the terminal apparatus; a selection unit that selects, from among a group of predetermined channel information candidates, a channel information candidate corresponding to the generated channel information; and a transmission unit that transmits, to a first node that performs scheduling about the terminal apparatus, indication information indicating the selected channel information candidate.
(FR) [Problème] L'invention a pour objet de permettre une réduction supplémentaire de la quantité d'informations à émettre d'un nœud à l'autre parmi deux nœuds portant en commun les traitements d'un réseau d'accès sans fil. [Solution] Un appareil selon l'invention comporte: une unité de génération d'informations qui effectue, sur la base d'un signal de liaison montante émis par un appareil terminal, une estimation de canal, générant ainsi des informations de canal concernant l'appareil terminal; une unité de sélection qui sélectionne, parmi un groupe d'informations de canal candidates prédéterminées, une information de canal candidate correspondant aux informations de canal générées; et une unité d'émission qui envoie, à un premier nœud effectuant une programmation concernant l'appareil terminal, des informations d'indication indiquant l'informations de canal candidate sélectionnée.
(JA) 【課題】無線アクセスネットワークの処理を分担する一方のノードから他方のノードへ送信される情報の量をより少なくすることを可能にすること。 【解決手段】本発明の装置は、端末装置により送信されるアップリンク信号に基づいてチャネル推定を行うことにより、上記端末装置についてのチャネル情報を生成する情報生成部と、予め定められたチャネル情報候補のグループの中から、生成された上記チャネル情報に対応するチャネル情報候補を選択する選択部と、上記端末装置についてのスケジューリングを行う第1のノードに、選択された上記チャネル情報候補を示す指示情報を通知する通知部と、を備える。
