    Abstract: A method of a user equipment (UE) in a wireless communication system is provided. The method includes, in case that a first message to perform a handover from a first base station to a second base station is received, from the first base station, performing a medium access control (MAC) reset, wherein performing the MAC reset includes stopping a power headroom report (PHR) periodic timer; receiving, from the second base station, first information related to a first uplink resource; in case that the first uplink resource is first allocated for a new transmission since the MAC reset is performed, starting the stopped PHR periodic timer; transmitting, to the second base station, a second message to confirm the handover using the first uplink resource; triggering a PHR, in case that the started PHR periodic timer expires; receiving, from the second base station, second information related to a second uplink resource; and transmitting, to the second base station, the triggered PHR using the second uplink resource.

    Abstract: Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. Disclosed is a method by which a terminal performs a random access, comprising: receiving, from a serving base station, a handover command including configuration information indicating a dedicated random access resource and a common random access resource determining whether to perform a random access by using at least one of the dedicated random access resource and the common random access resource according to predetermined criteria; and performing the random access on the basis of the determination result.

    Abstract: Methods and apparatuses are provided for transmitting a status report by a receiving device including an automatic repeat request (ARQ) entity and a hybrid ARQ (HARQ) processor, in a mobile communication system. The method includes transmitting, by the HARQ processor, a packet provided from the ARQ entity to a receiving device; receiving, by the HARQ processor, a packet including a status report including a reception status of the transmitted packet from the receiving device; and providing, by the HARQ processor, the status report to the ARQ entity. The status report is generated, by an ARQ entity of the receiving device at a transmission opportunity indicated by a HARQ processor of the receiving device, in response to the status report being triggered based on at least one triggering condition by the ARQ entity of the receiving device.

    Abstract: A method and apparatus are provided for controlling an active state in a mobile communication system. The method includes receiving, from a base station, information related to a starting position of an active state and information related to a length of a first timer; deriving the starting position of the active state based on the information related to the starting position; starting the first timer set to the length of the first timer and entering the active state at the derived starting position; extending the active state, in response to control data indicating a new transmission of user data being received on a control channel; and terminating the active state, based on a control signal indicating a termination of the active state and a second timer for extending the active state. The second timer is started while the first timer is running, and the active state is terminated by the expiration of the second timer.
