transmit, to the base station, a first indication indicative of an overheating state of the portable communication device using the first radio resource for the cellular communication;
receive, from the base station, a first radio resource control (RRC) connection reconfiguration message including a second indication indicative of a second radio resource decreased as compared with the first radio resource;
transmit, to the base station, a first RRC reconfiguration complete message in response to the first RRC connection reconfiguration message;
receive, from the base station, a second RRC connection reconfiguration message including a third indication indicative of a third radio resource increased as compared with the second radio resource; and
transmit, to the base station, a second RRC reconfiguration complete message in response to the second RRC connection reconfiguration message to indicate that the third radio resource is to be used for the cellular communication.
