Abstract: The 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 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 is provided for a terminal to transmit uplink data without a transmission resource previously allocated by a base station in a next generation mobile communication system. A method by a terminal includes while the terminal is in an inactive mode, receiving a paging message from a base station, identifying a paging identifier included in the paging message, if the paging identifier corresponds to a core network (CN) paging identifier, transmitting a first radio resource control (RRC) message, and if the paging identifier corresponds to a radio access network (RAN) paging identifier, transmitting a second RRC message.

Abstract: A method of a terminal in a wireless communication system is provided. The method includes receiving, from a base station, a message including first information configuring a medium access control (MAC) parameter for the terminal; identifying whether second information is configured in the first information, the second information indicating the terminal to skip an uplink transmission; receiving, from the base station, an uplink grant; and determining whether to skip a generation of a MAC protocol data unit (PDU) for the uplink grant based on the second information. The generation of the MAC PDU is skipped, in case that the uplink grant is addressed to a cell radio network temporary identifier (C-RNTI).

Abstract: The present disclosure relates to a communication technique for combining, with an 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 intelligent services (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 a user equipment in a first communication system according to the present invention comprises steps in which a user equipment in an inactive state: transmits a paging area update request message; checks whether or not a timer associated with a paging area update has expired; and transitions into an idle state if a response message for the paging area update request message has not been received until the timer has expired.

Abstract: A method, by a terminal, of performing a random access in a wireless communication system is provided. The method includes identifying a random access occasion configured for an active uplink (UL) bandwidth part (BWP) of a serving cell and when the serving cell is a special cell (SpCell) and an identity (ID) of an active downlink (DL) BWP does not correspond to an ID of the active UL BWP, switching the active DL BWP to a DL BWP with ID corresponding to the ID of the active UL BWP, based on BWP configuration information for the serving cell, and performing a random access on the switched DL BWP.
