Abstract: PROBLEM TO BE SOLVED: To efficiently select a relay station suitable for relaying between a mobile station and a base station using only easily derivable information.
SOLUTION: In the radio communication system 100, the mobile station has an identifier acquiring section 230 for acquiring an identifier of one or more relay stations within its communication range, and an information transmitting section 323 for making a selection request of the relay station by transmitting relay station information including the identifier of the relay station to the base station. The base station 120 has an information receiving section 260 for receiving the relay station information, a relay station selecting section 246 for selecting one relay station which is indicated by the identifier of the relay station information, through which the mobile station has to pass for communication with itself among the relay stations which are not communicating with itself, and a result transmitting section for transmitting the selected one relay station to the mobile station. The mobile station communicates with the base station via the relay station selected by the base station.

Abstract: PROBLEM TO BE SOLVED: To provide a communication method and a communication apparatus in which mobility can be enhanced and radio resources can be effectively utilized. SOLUTION: A control section 124 comprehends communication quality with a user terminal, selects a first modulation system based on the grasped communication quality, and grasps the amount of data (queue value) stored in a data storage section 131. When the grasped amount of data exceeds a threshold, the grasped amount of data is added to the amount of data in selecting the current modulation system, a second modulation system is selected based on the added amount of data and between the first modulation system and the second modulation system selected, any one modulation system is determined.
