    Abstract: The disclosure relates to a fifth-generation (5G) or sixth-generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method comprises receiving, from a base station, a physical downlink control channel (PDCCH) order for a random access procedure on a layer 1/layer 2 triggered mobility (LTM) candidate cell, transmitting a random access preamble for an early timing advance (TA) acquisition for the LTM candidate cell, based on the PDCCH order and receiving, from the base station, a cell switch command including a TA value of the LTM candidate cell, wherein a bandwidth part (BWP) operation is not performed for the LTM candidate cell based on the random access procedure being initiated by the PDCCH order.

    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 data until a cell of the first base station is released.

    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. 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.

    Abstract: A frequency measurement method performed by a user equipment (UE) in a wireless communication system is provided. The frequency measurement method includes: receiving a radio resource control (RRC) release message or system information including first frequency measurement configuration information for frequency measurement in an RRC inactive mode; performing frequency measurement in the RRC inactive mode based on the first frequency measurement configuration information; receiving first RRC resume message including an indicator requesting a measurement report in the RRC inactive mode; and transmitting an RRC resume complete message including the measurement report based on the indicator.
