Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring multiple logical channels; triggering a scheduling request (SR) associated with a first logical channel of the multiple logical channels; and if there is no SR resource corresponding to the first logical channel and if there is no on-going SR transmission on an SR resource corresponding to a second logical channel, initiating a random access procedure.

Abstract: In the present invention, a radio link control (RLC) entity of the receiving device receives an RLC service data unit (SDU) segment of a first RLC SDU. The RLC entity starts a first reassembly timer for the first RLC SDU if the RLC SDU segment of the first RLC SDU is the first one received for the first RLC SDU at the RLC entity. The receiving device uses a reassembly timer per RLC SDU segmented.

Abstract: A user equipment (UE) receives a physical downlink control channel (PDCCH) scheduling a data transmission, and starts a hybrid automatic repeat request (HARQ) round trip timer (RTT) timer for the data transmission. The HARQ RTT timer is set to a non-negative value associated with a radio network temporary identifier (RNTI) addressing the PDCCH.

Abstract: Provided is a method for performing a random access (RA) procedure by a terminal in an RRC-inactive (RRC_INACTIVE) state, in a wireless communication system. The method comprises the steps of: receiving, from a network, an indicator indicating whether access control can be applied to the terminal; when the indicator indicates that the access control can be applied, performing access control for an application or a service to be performed by the terminal; and performing a random access procedure according to a result of performing of the access control.
