Abstract: According to the present invention, a method by which a terminal transmits a buffer status report (BSR) in a wireless communication system comprises the steps of: receiving, from a base station, a message including information for a BSR request; triggering the BSR on the basis of the information; and transmitting the BSR to the base station. The triggered BSR is a periodic BSR, and the triggering step causes a timer for the periodic BSR to expire. The information for a BSR request is indicated by a polling field included in a medium access control (MAC) sub-head.

Abstract: The present disclosure relates to a communication technique for converging a 5G communication system, which is provided to support a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The disclosure may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety related service, or the like) based on the 5G communication technology and the IoT related technology. The disclosure relates to a method for recovering a beam into a correct beam according to a position of a terminal using a non-contention-based and contention-based beam failure recovery method in order to recover a beam failure in which communication is disconnected due to movement of a terminal or the like in a wireless communication system performing beam-based communication services.

Abstract: Methods and apparatuses are provided in which a first radio resource control (RRC) release message in an RRC connected state is received from a first base station. The first RRC release message includes first information configuring an RRC inactive state and second information associated with a paging area. A system information block 1 (SIB1) in the RRC inactive state is received from a second base station. A cell is identified that does not belong to the paging area based on the SIB1. An RRC resume request message is transmitted to the second base station to resume an RRC connection from the RRC inactive state. The RRC resume request message includes a cause value for updating the paging area. A second RRC release message for the RRC resume request message is received from the second base station. The second RRC release message includes third information associated with an updated paging area.
