Abstract: The present disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to various embodiments of the disclosure, there is provided a method of a terminal including a plurality of SIMs in a wireless communication system, the method including: based on a type of a SIM used for a current communication service of the terminal, determining whether to enable a dual connectivity feature of the terminal; and transmitting information on whether to enable the dual connectivity feature to a base station, wherein the terminal and the base station are configured to support the dual connectivity feature, wherein the plurality of SIMs include a first SIM and a second SIM, and the first SIM and the second SIM include different subscription information.

Abstract: An example method performed by a first terminal in a wireless communication system may include identifying a connection state of a second terminal, receiving capability information from the second terminal, if the second terminal is connected with the first terminal using short-range communication, and is not connected with a serving cell of the first terminal over a wireless network, and transmitting a list of at least one candidate cell identified based on the capability information to the second terminal.

Abstract: According to an embodiment of the present disclosure, a method performed by a user equipment in a wireless communication system, may include: receiving, from a base station, information for measurement, the information for measurement including frequency information related to at least one cell related to the measurement, or the frequency information and identifier information of the at least one cell; performing the measurement on a standalone (SA) cell excluding a cell matching a cell identified by information of at least one non-standalone (NSA) cell among the at least one cell, based on the information for the measurement and a specified NSA cell list including information of the at least one NSA cell; and transmitting, to the base station, a measurement report of the SA cell.

Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transfer rate. A method performed by a user equipment in a wireless communication system is provided. The method includes executing an application in the user equipment, identifying a user equipment route selection policy (URSP) rule mapped to the application, based on configuration information on the application, identifying a single-network slice selection assistance information (S-NSSAI) mapped to the application, based on the URSP rule mapped to the application, and transmitting a message requesting registration of the S-NSSAI mapped to the application to a core network via a base station. The S-NSSAI may correspond to a network slice selection assistance information (NSSAI) not allowed by the core network to be registered among NSSAIs configured for the user equipment.
