Abstract: The present invention relates to a method of performing uplink transmission by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving a configured grant (CG) activation command for a configured uplink grant; based on a size of the configured uplink grant not matching with a size of a pending protocol data unit (PDU) associated with an identified HARQ process, flushing a Hybrid Automatic Repeat Request (HARQ) buffer of the identified HARQ process; and transmitting a CG confirmation medium access control (MAC) control element (CE) using the identified HARQ process.

Abstract: The present invention relates to a method of transmitting buffer status report (BSR) by a node in a wireless communication system. In particular, the method includes the steps of: transmitting, to a parent node, a first BSR with starting a timer before receiving data from a child node; triggering a second BSR based on receiving the data from the child node; and based on the data not being transmitted to the parent node until expiration of the timer, transmitting, to the parent node, a scheduling request (SR) for transmission of the second BSR, wherein, based on the data being transmitted to the parent node before the expiration of the timer, the timer is stopped and the second BSR is canceled.

Abstract: A method for transmitting data units by a relay node configured with a first radio link control (RLC) entity and a second RLC entity in a wireless communication system is disclosed. Especially, the first RLC entity is active and the second RLC entity is inactive. The method comprises transmitting data units on the first radio link using a first RLC entity to a first node; activating the second RLC entity when a radio link problem occurs on the first radio link; and transmitting at least one data unit of the data units on the second radio link using the second RLC entity to a second node, wherein the at least one data unit is a data unit which is not successfully transmitted on the first radio link before the radio link problem occurs on the first radio link.

Abstract: The present invention relates to a method of transmitting a buffer size report (BSR) by a wireless node in a wireless communication system. In particular, the method includes the steps of: generating the BSR including a first bitmap; and transmitting the BSR to a network, wherein each bit of the first bitmap indicates whether a corresponding second bitmap is present or not in the BSR, wherein each bit of at least one second bitmap which is present in the BSR indicates whether buffer size information of a corresponding logical channel group (LCG) is present or not in the BSR.

Abstract: The present invention constructs L RLC PDUs, where L is larger than 1; and submit the L RLC PDUs to a medium access control (MAC) layer for a transmission opportunity. The L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device and a second RLC PDU not having the poll and having a highest sequence number (SN) among SNs of the L RLC PDUs. The present invention sets a state variable to a highest SN among SNs of RLC PDUs having the poll submitted to the MAC layer, upon submitting the first RLC PDU to the MAC layer.
