Title (EN) USER TERMINAL, WIRELESS BASE STATION, AND WIRELESS COMMUNICATION METHOD
(FR) TERMINAL D’UTILISATEUR, STATION DE BASE SANS FIL ET PROCÉDÉ DE COMMUNICATION SANS FIL
(JA) ユーザ端末、無線基地局及び無線通信方法
Abstract:
(EN) The purpose of the invention is to perform communication appropriately even when allocation is controlled in frequency units (e.g. in units of sub-carriers) that are smaller than resource allocation units in existing LTE systems. The invention comprises: a transmission unit that transmits a random access preamble (message 1) and a message 3 in random access operation; and a control unit that controls the transmission of said message 1 and said message 3 by associating a transmission parameter used for the transmission of said message 1 with the number of sub-carriers and/or the interval between sub-carriers which are/is used for the transmission of said message 3.
(FR) L'invention vise à réaliser une communication de manière appropriée, même lorsqu'une attribution est commandée en des unités de fréquence (par exemple des unités de sous-porteuses) qui sont plus petites que des unités d'attribution de ressources dans les systèmes LTE existants. L'invention comprend : une unité d'émission qui émet un préambule d'accès aléatoire (message 1) et un message (3) dans une opération d'accès aléatoire ; et une unité de commande qui commande l'émission dudit message (1) et dudit message (3) en associant un paramètre d'émission utilisé pour l'émission dudit message (1) au nombre de sous-porteuses et/ou l'intervalle entre les sous-porteuses qui est/sont utilisé(es) pour l'émission dudit message (3).
(JA) 既存のLTEシステムにおけるリソース割り当て単位よりも小さい周波数単位(例えば、サブキャリア単位)で割当てが制御される場合であっても通信を適切に行うこと。ランダムアクセス動作におけるランダムアクセスプリアンブル(メッセージ1)とメッセージ3を送信する送信部と、前記メッセージ1の送信に利用する送信パラメータと、前記メッセージ3の送信に利用するサブキャリア数及び/又はサブキャリア間隔と、を対応づけて前記メッセージ1と前記メッセージ3の送信を制御する制御部と、を有する。
