Abstract

An operating method of a user equipment supporting dual subscriber identity module (SIM) dual active (DSDA), the method including performing a first communication with a first base station through a first network via radio frequency (RF) transmission paths allocated to a first SIM, the transmission paths being included in a set of RF transmission paths of the user equipment, determining whether the set of RF transmission paths includes more than the RF transmission paths in response to a resource allocation request from a second SIM, the resource allocation request corresponding to a second communication with a second base station through a second network, and allocating at least one of the RF transmission paths to each of the first SIM and the second SIM based on a time division multiplexing (TDM) scheme in response to determining the set of RF transmission paths does not include more than the RF transmission paths.
