RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION METHOD, AND RADIO COMMUNICATION SYSTEM

摘要

It is possible to improve an error ratio characteristic in a radio communication device which relays communication between a mobile station and a base station. Among a modulation multi-valued number from a relay station to a mobile station and a modulation multi-valued number from the relay station to the base station, a low modulation multi-valued number is selected as a resource modulation multi-valued number for network coding and accordingly, a QPSK is used. Among S1+P1, the relay station allocates S1 which is a systematic bit of a high importance to the network coding resource with a higher priority. Among S1+P1, signals which have not been allocated to the network coding resource are allocated from the relay station to the base station resource. In this embodiment, S1 is allocated to a network coding resource while P1 is allocated to a resource for the base station from the relay station.
