RADIO COMMUNICATION METHOD AND RADIO COMMUNICATION DEVICE

摘要

Provided are a radio communication method and a radio communication device which can improve throughput characteristic and MCS multiplex degree without requiring a special additional function. A line quality measuring unit (21) measures the line quality between a mobile station (3) and a relay station (1) according to a signal received from the mobile station (3). An MCS prediction unit (20) predicts which MCS is to be used according to the line quality. An MCS extraction unit (16) extracts the MCS which has been reported to the mobile station (3) by a base station (4). The MCS between the extracted mobile station (3) and the base station(4) is inputted to an MCS comparison unit (18). The MCS comparison unit (18) compares the predicted level of the MCS between the mobile station (3) and the relay station (1) to the reported level of the MCS between the reported mobile station (3) and the base station (4). If the levels are near to each other, it is judged that the next signal is received via the relay station (1). If the level of the MCS between the mobile station (3) and the relay station (1) is lower than the level of the MCS between the mobile station (3) and the base station (4) by a predetermined value or more (multiplex degree is low), it is judged that the next signal is directly received.
