The disclosure relates to a 5generation (5G) or pre-5G communication system for supporting higher data transfer rates than 4generation (4G) communication systems such as long term evolution (LTE). According to various embodiments of the disclosure, a method for operating a base station in which a Master Cell Group (MCG) is configured in a wireless communication system may include: detecting a failure of a Primary Cell (PCell) of a Secondary Cell Group (SCG) (PScell), transmitting inter-Radio Access Technology (RAT) measurement configuration information to a terminal based on the detection, and transmitting information on a cell identified based on the measurement configuration information to a base station in which the SCG is configured.

Method and device for handling link failure in wireless communication system

The present disclosure relates to a communication scheme and system for converging a 5generation (5G) communication system for supporting a data rate higher than that of a 4generation (4G) system with an internet of things (IoT) technology. The present disclosure is applicable to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. A proposed method for a base station to transmit information controlling configuration of an uplink (UL) secondary component carrier (SCC) corresponding to a secondary cell in a wireless communication system supporting carrier aggregation (CA) includes identifying first information associated with an uplink electric field of a primary cell, transmitting measurement configuration information associated with the secondary cell to a terminal, receiving a measurement report message associated with the secondary cell from the terminal, identifying second information associated with a downlink electric field of the secondary cell based on the measurement report message, and transmitting the information controlling configuration of the UL SCC of the secondary cell to the terminal based on at least one of the first information or the second information.

Method and apparatus for transmitting and receiving signals in wireless communication system

A scheduling apparatus and a method for interference control in a mobile communication system supporting a carrier aggregation or dual connectivity or multi-connectivity technology in which a terminal uses a plurality of frequency resources at the same time are provided. Specifically, a first base station in a wireless communication system includes a transceiver and a processor connected to the transceiver and configured to obtain resource information of a second base station transmitted by the second base station, determine a resource assignment pattern based on the resource information of the second base station, assign uplink (UL) resources of the LTE base station for an UL channel based on the resource assignment pattern to reduce interference, and assign uplink (UL) resources of the first base station for an UL channel based on the resource assignment pattern to reduce interference.

Scheduling apparatus and method for interference control in mobile communication system

A method and an apparatus for group communication in a mobile communication system are provided. The method includes receiving a first message including information related to a discontinuous reception (DRX) cycle from a network device, transmitting a second message based on the first message to at least one terminal, and transmitting data to the at least one terminal based on the information related to the DRX cycle.

Method and apparatus for group communication in wireless communication system

According to an embodiment of the present invention, provided are a method for providing a broadcast service of an MBMS coordination entity (MCE) in a mobile communication system, and an MCE for performing the same. The method comprises the steps of: transmitting a terminal counting request message to at least one base station in a multicast-broadcast single frequency network (MBSFN) area; receiving a counting result message comprising the number of terminals receiving a multimedia broadcast multicast service (MBMS) session for each cell of the base station from the base station; and determining MBMS resource allocation for each cell in the MBSFN area on the basis of the counting result message. In addition, it is possible to provide a base station and a terminal operating together with the MCE, and a method for the operation thereof.

Method and apparatus for operating resources in wireless communication system

A method for group communication of a broadcasting server in a wireless communication system is provided. The method for group communication of a broadcasting server includes receiving a data packet from a content server, generating a transmission packet by copying the data packet, and transmitting the generated transmission packet to a base station.

A method and an apparatus for reducing delay in enhanced multimedia broadcast multicast services (eMBMS)-based group communication are provided. The method includes receiving the user packet, including information of a time stamp assigned by a broadcast/multicast service center (BM-SC), from the BM-SC, and transmitting the user packet to a terminal through a physical multicast channel based on information of the time stamp, wherein the time stamp is assigned at an interval set to a value less than a multimedia broadcast multicast services (MBMS) scheduling period.

Enhanced MBMS-based signal transmission/reception method

A method and apparatus for transmitting Multimedia Broadcast Multicast Service (MBMS) data for use in a Long Term Evolution (LTE) system is provided. The method includes generating information for use in determining whether a broadcast area changes on inter-cell movement of a terminal, generating a system information block (SIB) including the generated information, and broadcasting the SIM.
