Abstract:
1. A radio communication method in reverse link by multicarrier using at least a first carrier and a second carrier that is adjacent to the first carrier with a predetermined frequency interval, the method comprising the steps of: calculating a transmission power difference in a predetermined cycle between a transmission power value of the first carrier and a transmission power value of the second carrier; determining whether the transmission power difference exceeds a threshold set on the basis of a maximum transmission power difference allowable between the first carrier and the second carrier; stopping a transmission of reverse link data using one of the first carrier and the second carrier with a larger transmission power value for a certain period, in a case where the transmission power difference exceeds the threshold set on the basis of the maximum transmission power difference; and determining whether the transmission power difference is increasing, on the basis of the transmission power differences calculated in the predetermined cycle, wherein in the step of stopping the transmission of the reverse link data, the transmission of reverse link data using one of the first carrier and the second carrier with a larger transmission power value is stopped for a certain period, in a case where the transmission power difference is determined as increasing.
