Electronic device supporting dual connectivity and operation method thereof

Abstract

According to an embodiment, an electronic device may comprise at least one communication processor. The at least one communication processor may be configured to: establish, based on dual connectivity, a first connection based on a first radio access technology (RAT) and a second connection based on a second RAT; transmit first uplink data based on the first connection and transmit second uplink data based on the second connection, wherein a throughput corresponding to the second connection may be a first value; identify at least one first parameter associated with the first connection and at least one second parameter associated with the second connection; perform at least one operation for transmitting, based on the second connection, uplink (UL) data with a throughput less than the first value, based on the at least one first parameter satisfying a first condition indicating a good uplink channel state and that the at least one second parameter satisfying a second condition indicating a poor uplink channel state; and based on performing the at least one operation, transmit third uplink data based on the first connection and transmit fourth uplink data based on the second connection, wherein a throughput corresponding to the second connection may be less than the first value.
