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

Abstract:
(EN) A user terminal which performs MIMO transmission with a wireless base station is provided with: a control unit which generates first channel estimation information on the basis of a reference signal transmitted from the wireless base station, and which generates second channel estimation information by subjecting the first channel estimation information to an operation concerning removal of an interference signal; and a post-coder which, on the basis of the second channel estimation information, detects a desired signal by subjecting a data signal transmitted from the wireless base station to post-coding.
(FR) Selon la présente invention, un terminal d'utilisateur qui effectue une transmission MIMO au moyen d'une station de base sans fil comprend : une unité de commande qui génère des premières informations d'estimation de canal sur la base d'un signal de référence transmis à partir de la station de base sans fil, et qui génère des secondes informations d'estimation de canal en soumettant les premières informations d'estimation de canal à une opération concernant l'élimination d'un signal d'interférence; et un post-codeur qui, sur la base des secondes informations d'estimation de canal, détecte un signal souhaité en soumettant un signal de données transmis de la station de base sans fil à un post-codage.
(JA) 無線基地局とMIMO伝送を行うユーザ端末が、無線基地局から送信された参照信号に基づいて第1のチャネル推定情報を生成し、当該第1のチャネル推定情報に対して干渉信号の除去に関する操作を施して第2のチャネル推定情報を生成する制御部と、第2のチャネル推定情報に基づいて、無線基地局から送信されるデータ信号に対してポストコーディングを施して希望信号を検出するポストコーダと、を備える。
