Mobile station used as a repeater station, corresponding base station, system, method and program

摘要

When a mobile station communicates with a base station (10) by way of one or a plurality of other mobile stations (11-16), the mobile station acting as a relay station determines whether the data demodulated after being received is reception data for the mobile station or transfer data to be transmitted to the other mobile station or the base station (10), decides a modulation mode suitable for transmitting sum data of the transfer data and transmission data if the transmission data is generated in the mobile station, and transmits the sum data while modulating the sum data according to the modulation mode decided. The base station demodulates a reception signal relayed by the mobile stations according to the modulation mode of the mobile station having directly communicated with the base station (10), and identifies each user data multiplexed. <IMAGE>
