    Abstract: A method and an apparatus for monitoring device-to-device (D2D) transmission in a connected state in a communication system supportive of a D2D scheme are provided. The method includes monitoring, by a D2D user equipment (UE), a D2D transmission during a D2D resource cycle and a discontinuous reception (DRX) cycle in a radio resource control (RRC) state, transmitting an indication including a capability of the UE to a base station, and reestablishing an RRC connection from the base station, wherein the D2D resource cycle and the DRX cycle are configured not to overlap each other based on the indication.

    Abstract: The present disclosure relates 5G or pre-5G communication systems for supporting higher data transmission rate than those by LTE or other post-4G communication systems. According to an embodiment of the present disclosure, a method for allocating a resource in a communication system includes determining a beam to be used for data communication between a UE and the base station based on beam feedback information from the UE. The method also includes releasing resource allocation for a beam used previously depending on whether the determined beam is changed from the previously used beam, allocating a resource for the determined beam, and transmitting information related to the resource allocation for the determined beam to the UE.

    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate than a 4G communication system such as LTE. The method for device to device communication according to the present disclosure comprises: a step of receiving, by a terminal, search data from search resources for relay search within a specified search-receiving resource pool, and decoding the same; a step of measuring, by the terminal, link qualities of the search resources which deliver demodulation reference signals, from the search resources corresponding to successfully decoded search data; and a step of filtering a link quality corresponding to an identifier of a specific relay among the measured link qualities.
