Abstract: The present disclosure relates to a 5G or pre-5G communication system to be provided in order to support a higher data transmission rate following 4G communication systems such as LTE. Disclosed are a method and device for improving device searching in a D2D communication system supporting direct communication between devices. The method comprises the steps of: generating a search signal including search information; selecting a transmission resource to transmit the search signal; transmitting the search signal through the selected transmission resource; and when a request signal requesting additional information on the search from a counterpart device that has received the search signal is received, transmitting a confirmation signal including the requested additional information to the counterpart device. The present disclosure relates to a communication technique and system which combine a 5G communication system, for supporting a higher data transmission rate following 4G systems, with IoT technology.

Abstract: A method for providing a cooperative communication service by a macro Base Station (BS) in a mobile communication system is provided. The method includes generating at least one small cell BS group by grouping small cell BSs if there are small cell BSs of which a number is equal to or larger than a threshold small cell BS number within a service coverage of the macro BS, establishing a cooperative interface with a representative small cell BS among small cell BSs included in the at least one small cell BS group, and providing a cooperative communication service with the at least one small cell BS group using the cooperative interface.

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: The present disclosure provides a method and apparatus for communicating data packets in a cloud cell. In one embodiment, a network node from which data packets are received is identified by the BS. If the data packets are received from a data gateway, a network node to which the data packets to be sent is identified. If the data packets are to be sent to a slave BS, partial processing is performed on the data packets by the master BS. Furthermore, partially processed data packets are transmitted to the slave BS so that the slave BS performs complete processing on the partially processed data packets and transmits the completely processed data packets to the MS. If the data packets are to be sent to the MS, then complete processing of the data packets is performed by the BS and transmitted to the MS.
