Patent ID: 8582671

Claim:
A multicarrier communication apparatus which transmits a multicarrier signal including a plurality of carriers to which transmission data of a plurality of users are allocated, the multicarrier communication apparatus comprising: a scheduler that schedules transmission opportunities of the transmission data of the plurality of users in accordance with predetermined scheduling information; an evaluator that evaluates whether or not the peak of the multicarrier signal exceeds a predetermined threshold value; and a suppressor that halts transmission of at least some of the transmission data of the plurality of users by a user unit based on the scheduling information upon decision by said evaluator that the result of the evaluation exceeds the threshold value, wherein said suppressor performs the halt processing repeatedly to the transmission data in order of increasing of the width of the frequency band used for the individual transmission data, based on frequency band information in use as element information of the scheduling information, until said evaluator decides that the peak does not exceed the threshold value.
