Abstract: The present invention relates to an electronic device, comprising a modem which: when simultaneously connected to a master cell group according to a first communication mode and a secondary cell group according to a second communication mode, if a transmission power of a first uplink signal transmitted to the master cell group is greater than or equal to a preset maximum transmission power, controls a plurality of power amplification units such that transmission of a second uplink signal to be transmitted to the secondary cell group is deferred; and, if the transmission of the second uplink signal remains deferred for a preset time period, stops the transmission of the first uplink signal for a certain period of time and transmits the second uplink signal, thereby maintaining connectivity to the secondary cell group even when the transmission of the second uplink signal is deferred.

Abstract: The present disclosure relates to an electronic device capable of performing both fourth-generation (4G) and fifth-generation (5G) communications, which includes a communication unit configured to perform wireless communication with a base station according to at least one of a first communication method and a second communication method, and a modem configured to determine whether an establishment of a communication link according to the first communication method is allowed when a first communication link command according to the first communication method is to received from the base station, and to establish the communication link according to the first communication method based on a result of the determination or re-attempt to establish the communication link according to the first communication method through a recovery process, and wherein the modem interrupts the recovery process to prevent repeated exchange of unnecessary messages with the base station when the establishment of the communication link according to the first communication method is failed even though the establishment of the communication link according to the first communication method is attempted a preset number of times.
