    Abstract: A method and apparatus for performing a state transition for Device to Device (D2D) communication are provided. The method includes determining whether D2D initiation is required, while a terminal is operating in a first or a second state defined by EPS (Enhanced Packet System) Mobility Management (EMM)-Deregistered and EPS Connection Management (ECM)-IDLE at a Non-Access Stratum (NAS) layer and Radio Resource Control (RRC)-IDLE. If the D2D initiation is required, the method includes transitioning to a third state defined by EMM-Registered and ECM/RRC-Connected and performing the D2D initiation through a mobile communication network. If a deactivation condition is satisfied or a D2D state update is completed in the third state, the method includes transitioning to a fourth state defined by EMM-Registered and ECM/RRC-IDLE, and if a state update or scheduling for D2D communication is required in the fourth state, the method includes transitioning to the third state.

    Abstract: A method for controlling a path between terminals in a wireless communication system includes measuring a channel quality of a direct path with the another terminal when receiving a request for measuring the channel quality of the direct path from a higher entity, transmitting a first message comprising a result of the measuring the channel quality to the higher entity, and, when receiving a second message to instruct to switch to the direct path from the higher entity, setting the direct path with the another terminal. another embodiments including a terminal and a network entity are also disclosed.

    Abstract: The present 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 a long term evolution (LTE). A method for performing a paging process by a base station (BS) in a wireless communication system is provided. The method includes identifying that paging for a mobile station (MS) is initiated, and transmitting a paging indicator including a first part indicating a paging identifier (ID) and a second part indicating a group in which at least one MS which needs to receive a paging message is included.
