WIRELESS COMMUNICATION SYSTEM, BASE STATION, MOBILE STATION, AND WIRELESS COMMUNICATION METHOD

摘要

A wireless communication system includes a base station (100) and a mobile station (200) that transmit/receive a data signal and a control signal. The base station (100) includes a control unit (100a) and a communication unit (100b). The control unit (100a) allocates an E-Control region that is a resource across a sub frame that transmits a PDSCH and one previous sub frame to an E-PDCCH including resource allocation information related to the PDSCH. The communication unit (100b) transmits the E-PDCCH to the mobile station (200) using the E-Control region. The mobile station (200) includes a communication unit (200b) and a control unit (200a). The communication unit (200b) receives the E-PDCCH transmitted from the base station (100) using the E-Control region. The control unit (200a) demodulates the PDSCH based on the resource allocation information related to the PDSCH included in the E-PDCCH.
