Patent Searching and Data


Title:
RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION METHOD, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/029771
Kind Code:
A1
Abstract:
A reception device (200a) transmits reception device state information indicating a modulation method and a transmission path encoding method corresponding to the reception device (200a).  A transmission device determines the mapping method of a downlink signal to be transmitted to the reception device (200a) in accordance with the received reception device state information.  When the reception device (200a) is compatible with the BICM-ID,  the reception device (200a) transmits reception device state information indicating that the reception device (200a) is compatible with the BICM-ID.  This realizes a backward compatibility with a communication system employing the gray mapping and enables application of the BICM-ID.
