Claim of US Patent No. 10,368,311

1. A communication method of an electronic device using carrier aggregation, the method comprising:determining, using at least one processor, a primary component carrier (PCC) from one of a first channel or a second channel according to a control signal received from a base station,
comparing, using the at least one processor of the electronic device, an amount of current consumed by a first transceiver which operates the first channel with an amount of current consumed by a second transceiver which operates the second channel after a predetermined time; and
determining, using the at least one processor, the primary component carrier (PCC) from at least one of the first channel or the second channel according to the compared result,
wherein the comparing of the amount of the current consumed by the first transceiver and the amount of the current consumed by the second transceiver comprises:
comparing an amount of current consumed per unit time by the first transceiver with an amount of current consumed per unit time by the second transceiver, using a table including the amount of current consumed per unit time by the first transceiver based on a change of a transmit power of the first transceiver and the amount of current consumed per unit time by the second transceiver based on a change of a transmit power of the second transceiver, and wherein the determining the PCC comprises:
determining, in a state where the first channel is set to the PCC, if the amount of the current consumed by the first transceiver is greater than the amount of the current consumed by the second transceiver, the second channel as a new PCC.
