摘要： Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. A method for communicating with user equipment (UE) by a base station is disclosed. The method comprises the steps of: identifying a type of one or more services required by the UE; notifying the UE of information on a configuration of a medium access control (MAC) layer and a physical (PHY) layer configured according to the identified type of one or more services; and communicating with the UE on the basis of the information on the configuration of the MAC layer and the PHY layer configured according to the identified type of one or more services.

摘要： A method and an apparatus of cooperating with a plurality of base stations in a wireless communication system. A cloud cell is configured with a plurality of base stations that cooperate with each other for a mobile station and synchronizes user contexts for serving the mobile station among the plurality of base stations included in the cloud cell, and the plurality of base stations cooperate with each other to provide a communication service to the mobile station. The present disclosure reduces generation of a handover when the mobile station moves between base stations, and increases the data yield of the mobile station by transmitting and receiving data in cooperation with base stations in a cloud cell at a shaded area or a cell border.

摘要： 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 Long Term Evolution (LTE). Embodiments herein provide a method for triggering a transmission of a UE-to-Network relay indication comprising receiving, by UE, one of UE-to-Network relay criteria broadcasted by a base station, measuring, at the UE, a link quality parameter between the UE and the base station, detecting, by the UE, that the link quality parameter meets the UE-to-Network relay criteria, and transmitting, by the UE, the UE-to-Network relay indication (i.e. discovery message indicating itself as the UE-to-Network relay) on a Device to Device (D2D) discovery channel.

摘要： A device to device (D2D) communication apparatus and method are provided. The D2D communication apparatus includes a transceiver configured to receive resource configuration information indicating D2D resources configured in a serving cell from a base station (BS) of the serving cell, and a controller configured to determine locations of resources for transmission or reception of signals for D2D communication based on the resource configuration information. The resource configuration information includes information about length of common D2D resources configured in a plurality of cells and additional D2D resources configured in the serving cell and information about length of common and additional D2D resources of a cell that configures maximum-sized additional D2D resources among the serving cell and neighboring cells.

摘要： 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 transmitting a discovery message in a communication system is provided. The method includes detecting a need for transmitting a discovery message in a serving cell in which a direct discovery process is unsupportable; detecting a cell other than the serving cell; and transmitting the discovery message based on system information if the system information is broadcasted in the cell.

摘要： A method for being allocated a discovery resource by a user equipment (UE) in a communication system supporting a device to device (D2D) scheme is provided. The method includes determining whether a discovery resource request message may be transmitted to a network entity; transmitting the discovery resource request message to the network entity based on the determining result; and receiving a discovery resource response message as a response message to the discovery resource request message from the network entity.

摘要： The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data rate beyond a 4G communication system such as LTE. A method for controlling relay traffic by a base station in a wireless communication system supporting device to device (D2D) communication according to an embodiment of the present invention comprises checking whether received traffic is relay traffic; if the received traffic is the relay traffic, identifying a port number in each cluster of the relay traffic; determining the priority of the relay traffic according to the port number; and transmitting, to a relay terminal, a packet based on the determined priority.

摘要： The present disclosure relates to a 5G or pre-5G communication system that is to support higher data transmission rates after 4G communication systems such as LTE. A method, by a MeNB, for switching a SeNB communicating with a UE in a wireless communication system, provided in an embodiment of the present disclosure, includes receiving, from the UE, a measurement report (MR) of the at least two SeNB neighboring with the UE, determining whether predetermined switch criteria are satisfied based on the MR, and transmitting, to the UE and a first SeNB or a second SeNB, a switch message indicating switching of an SeNB cooperating with the MeNB for communication with the UE from the first SeNB to the second SeNB, based on whether the switch criteria are satisfied.

摘要： Hybrid Automatic Repeat Request (HARQ) operation in an asymmetric multicarrier communication network environment is performed, in one embodiment, by receiving resource allocation information from a base station, transmitting the HARQ packet to the base station in a transmit time interval (TTI) corresponding a first or second partition of an uplink allocation interval on a second carrier, and receiving HARQ feedback information corresponding to a previous HARQ packet transmission. A TTI in a subsequent uplink allocation interval is determined based on the partition of the uplink allocation interval in which the HARQ packet is transmitted if the HARQ feedback information indicates negative acknowledgement. The HARQ packet is transmitted to the base station in the determined transmit time interval of the subsequent uplink allocation interval on the second carrier.

摘要： 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.
