    Abstract: The disclosure relates to a communication technique and a system thereof that fuses a 5G communication system for supporting higher data rate after a 4G system. The disclosure is enabled to be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety related services, etc.) based on 5G communication technology and IoT related technology. A method for performing a random access by a terminal is provided. The method includes receiving information for performing a random access from a base station (BS), determining a frequency band to perform the random access among a first frequency band and a second frequency band based on the information for performing the random access, and transmitting a first random access preamble to the BS on the determined frequency band.

    Abstract: A communication method of a terminal for saving a battery of a terminal and reducing a signaling overhead when small data are processed is provided. The communication method includes receiving, from a base station, a first message including at least one of first information indicating whether a first signaling optimization is allowed for the terminal, or second information indicating whether a second signaling optimization is allowed for the terminal, transmitting, to the base station, a second message including at least one of third information indicating whether the first signaling optimization is supported by the terminal, or fourth information indicating whether the second signaling optimization is supported by the terminal, and receiving, from the base station, a third message including fifth information indicating a signaling optimization supported for the terminal.

    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 of a terminal in a wireless communication system according to the disclosure includes receiving, from a first base station, a message including a command of handover from a first base station to a second base station through radio resource control (RRC) signaling; identifying the message includes information indicating dual protocol stack handover; and receiving, from the first base station, data until a cell of the first base station is released in case that the message includes information indicating dual protocol stack handover.

    IPC: H04W36/00

    Abstract: The present disclosure relates to a communication technique for combining, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and to a system therefor. The present disclosure may be applied to an intelligent service (e.g., a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, security and safety-related service, etc.), based on a 5G communication technology and an IoT-related technology. The present disclosure suggests a method for effectively performing a standby mode operation in a next generation mobile communication, and a device therefor and, more particularly, to a method for efficiently reselecting a cell, and a device therefor. Also, the present disclosure relates to: a method for making a report, including beam measurement information, at the time of measurement reporting of a user equipment, and a device therefor; a method for performing measurement reporting by way of layer 1/layer 2 signaling, and a device therefor; and a method for changing between RRC modes including an RRC inactive mode, and a device therefor.
