    Abstract: An electronic device configured to apply, to a first power amplifier (PA) input, one or more updated memory digital pre-distorter (mDPD) coefficient values is provided. The electronic device includes a processor; and a memory including a non-transitory computer readable storage medium storing instructions that, when executed, cause the processor to preload, from values stored in the memory of the electronic device, one or more mDPD coefficient values; transmit a training signal sequence while using the preloaded one or more mDPD coefficient values; receive the training signal sequence; update the one or more mDPD coefficient values based on the transmitted training signal sequence, the received training signal sequence, and the preloaded one or more mDPD coefficient values; and apply the updated one or more mDPD coefficient values to distort the first PA input.

    Abstract: The present disclosure relates to a communication method which fuses a 5G communication system with IoT technology to support a higher data transfer rate than a 4G system, and a system thereof. The present disclosure may be applied to intelligent services such as smart homes, smart buildings, smart cars or connected cars, healthcare, digital education, retail business, security and safety services, etc., based on 5G communication technologies and IoT related technologies. More specifically, a method for operating a base station in a mobile communication system using an unlicensed band, according to the present invention, comprises the steps of: transmitting and receiving data to and from a terminal in a first cell; establishing a signal transmission timing related to a start symbol of a slot of a subframe for a second cell; occupying a resource by executing a sensing operation in a band corresponding to the second cell; and executing communication with the terminal in the occupied resource on the basis of the established signal transmission timing.

    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 present disclosure relates to a communication technique which combines a 5G (5th Generation) communication system, for supporting a higher data transmission rate following 4G (4th Generation) systems, with IoT (Internet of Things) technology, and to a system for the communication technique. The present disclosure may be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security, and safety-related services), based on 5G communication technology and IoT-related technology. The present invention relates to a method and device for receiving broadcast information by means of a terminal in a communication system. The method for receiving broadcast information by means of a terminal in a communication system according to an embodiment of the present invention comprises the processes of: receiving a signal including broadcast information from a base station; using a repeating pattern of the signal and determining a value for autocorrelation; determining whether coverage enhancement is supported by the base station on the basis of the value for the autocorrelation; acquiring the broadcast information through decoding of the signal when the base station supports coverage enhancement; and moving to another cell or another center frequency and implementing initial connection when the base station does not support coverage enhancement.
