Claim of US Patent No. 10,560,906

1. An integrated circuit which, in operation, controls a process of a communication apparatus, the process comprising:calculating transmission power of a plurality of uplink transmissions on a plurality of cell groups, the plurality of cell groups including a first cell group including one or a plurality of cells and a second cell group including one or a plurality of cells; and
preferentially allocating, in a case where an uplink channel of the first cell group on which uplink control information is multiplexed and a plurality of reference signals are simultaneously transmitted using the plurality of cell groups of the first cell group and the second cell group, transmission power with respect to the uplink channel of the first cell group on which the uplink control information is multiplexed over the plurality of reference signals,
wherein the allocating step, when preferentially allocating the transmission power with respect to the uplink channel of the first cell group on which the uplink control information is multiplexed over the plurality of reference signals, performs control of uniformly reducing the transmission power of one or more reference signals of the second cell group among the plurality of reference signals.
