Abstract: Provided is a method for managing synchronization with a network. The method includes detecting, by a dual SIM dual standby user equipment (a DSDS UE), a radio frequency resume event (an RF resume event); transmitting, by the DSDS UE, at least one uplink dedicated physical control channel (at least one UL-DPCCH) to the network in response to the RF resume event being detected, wherein the at least one UL-DPCCH is transmitted irrespective of a signal to interface ratio quality (an SIR quality) on a downlink dedicated physical control channel (a DL-DPCCH) of the network being below a first quality threshold; and managing, by the DSDS UE, a downlink (a DL) synchronization with the network.

Abstract: The disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as long-term evolution (LTE). A method of operating a terminal in a wireless communication system and an apparatus therefor are provided. The method includes detecting one or more states associated with antennas arranged in the terminal, activating a first antenna, among the antennas, based on the one or more states associated with antennas and deactivating a second antenna, among the antennas, based on the one or more states associated with the antennas.
