Abstract: front page image
(EN)A wireless communication system comprises: a base station (100) that transmits/receives data signals and control signals; and a mobile station (200). The base station (100) comprises a control unit (100a) and a communication unit (100b). The control unit (100a) allocates an E-Control region, which is a resource being astride both a subframe in which a PDSCH is transmitted and the immediately preceding subframe, to an E-PDCCH that includes resource allocation information related to the PDSCH. The communication unit (100b) uses the E-Control region to transmit the E-PDCCH to the mobile station (200). The mobile station (200) comprises a communication unit (200b) and a control unit (200a). The communication unit (200b) uses the E-Control region to receive the E-PDCCH transmitted from the base station (100). The control unit (200a) demodulates the PDSCH on the basis of the resource allocation information related to the PDSCH and included in the E-PDCCH.
(FR)La présente invention se rapporte à un système de communication sans fil comprenant : une station de base (100) qui transmet et reçoit des signaux de données et des signaux de commande ; et une station mobile (200). La station de base (100) comprend un module de commande (100a) et un module de communication (100b). Le module de commande (100a) alloue une région de E-contrôle, qui est une ressource à cheval à la fois sur une sous-trame dans laquelle un PDSCH est transmis et sur la sous-trame qui précède immédiatement, à un E-PDCCH qui comprend des informations d'allocation de ressources relatives au PDSCH. Le module de communication (100b) utilise la région de E-contrôle pour transmettre le E-PDCCH à la station mobile (200). La station mobile (200) comprend un module de communication (200b) et un module de commande (200a). Le module de communication (200b) utilise la région de E-contrôle pour recevoir le E-PDCCH transmis en provenance de la station mobile (100). Le module de commande (200a) démodule le PDSCH sur la base des informations d'allocation de ressources relatives au PDSCH et qui sont incluses dans le E-PDCCH.
(JA) 無線通信システムは、データ信号及び制御信号を送受信する基地局100と移動局200とを有する。基地局100は、制御部100aと、通信部100bとを有する。制御部100aは、PDSCHに関するリソース割当情報を含むE-PDCCHに対して、PDSCHを送信するサブフレームと一つ前のサブフレームとを跨ぐリソースであるE-Control regionを割り当てる。通信部100bは、上記E-Control regionを用いてE-PDCCHを移動局200に送信する。移動局200は、通信部200bと、制御部200aとを有する。通信部200bは、基地局100から送信されたE-PDCCHを、E-Control regionを用いて受信する。制御部200aは、E-PDCCHに含まれる、PDSCHに関するリソース割当情報に基づいて、PDSCHを復調する。
