    Abstract: The present disclosure relates to a communication method for converging IoT technology with 5G communication systems for supporting higher data transmission rates than beyond 4G systems, and to a system therefor. The present disclosure may be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The present invention characterizes in a method for a terminal of a wireless communication system, wherein the method comprises the steps of: receiving channel or reference signal configuration information including beam-related configuration information via higher layer signalling; transmitting and receiving the channel or a reference signal to and from a base station on the basis of the beam-related configuration information; receiving beam change information for the channel or reference signal; and transmitting and receiving the channel or reference signal of a plurality of component carriers to and from the base station on the basis of the beam change information, wherein the beam-related configuration information and the beam change information include transmission configuration indicator (TCI) state information of the channel or reference signal.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method and apparatus of a wireless network are disclosed. The method includes transmitting a first request message to request allocation of a multimedia broadcast multicast service (MBMS) group identifier from a service capability server/application server (SCS/AS) to a service capability exposure function (SCEF), the first request message including an external group identifier and an SCS/AS identifier, and receiving a first response message including the MBMS group identifier from the SCEF to the SCS/AS.

    Abstract: The disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The disclosure may be applied to an intelligent service (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology. A method is provided for receiving a CSI-RS in a communication system. The method includes acquiring, by a UE, a configuration for a resource set including a resource set identifier, information for at least one CSI-RS resource, and repetition information, wherein a number of the at least one CSI-RS resource is up to a maximum number of CSI-RS resources per resource set, and the repetition information is set as either on or off; acquiring, by the UE from, a CSI-RS resource configuration per CSI-RS resource including a CSI-RS resource identifier, information for a number of CSI-RS ports, and information for an OFDM symbol for the CSI-RS, wherein the number of the CSI-RS ports of the at least one CSI-RS resource within the resource set is 1 or 2, and the at least one CSI-RS resource within the resource set is regarded to be transmitted in different OFDM symbols, in case that the repetition information is set as on; and transmitting CSI based on the configuration for the resource set.
