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: acquiring a reverse link transmission power value of the first carrier from a radio communication terminal connected via the first carrier; acquiring a reverse link transmission power value of the second carrier from a radio communication terminal connected via the second carrier; calculating a transmission power difference between the reverse link transmission power values of the first carrier and 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; assigning a first time frame used for transmitting reverse link data by using the first carrier and a second time frame used for transmitting reverse link data by using the second carrier in a manner that the two time frames do not overlap with each other on a time axis, in a case where the transmission power difference exceeds the threshold set on the basis of the maximum transmission power difference; notifying the radio communication terminal connected via the first carrier, of the first time frame; and notifying the radio communication terminal connected via the second carrier, of the second time frame.
