Abstract: The present disclosure relates to a method for transmitting a data unit on uplink transmission resources based on processing time of the data unit in a wireless communication system. In particular, the method includes the steps of: configuring a first configured grant (CG) configuration and a scheduling request (SR) configuration related to the CG configuration, wherein the first CG configuration comprises first CG grants and the SR configuration comprises SR resources related to the CG grants; receiving a data unit from an upper layer; determining whether the data unit can be transmitted on one of the first CG grants of the first CG configuration or not; based on it being determined that the data unit cannot be transmitted on the one first CG grant, transmitting a SR message on a SR resource related to the CG grant; receiving a dynamic uplink grant in response to the SR message; and transmitting the data unit on the dynamic uplink grant.

Abstract: The present disclosure relates to a method of receiving data units by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a first data unit based on a Group-Radio network temporary identifier (G-RNTI) from a network; decoding the first data unit and identifying a logical channel related to the first data unit based on the G-RNTI; based on decoding the first data unit failing, transmitting a negative response related to the first data unit to the network; receiving a second data unit based on a Cell-RNTI (C-RNTI) from a network; decoding the second data unit; and based on the second data unit being a retransmitted data unit of the first data unit, identifying the logical channel on based the G-RNTI.

Abstract: The present disclosure relates to a method of performing a Random Access (RA) procedure by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving RA resource information related to a first RA resource set and at least two second RA resource sets from a network: transmitting at least one first RA preamble using the first RA resource set to the network: and based on a number of the at least one first RA preamble transmitted being greater than or equal to a threshold value or based on a fallback random access response (RAR) being received, transmitting at least one second RA preamble using one of the at least second RA resource sets to the network, wherein the one second RA resource set is determined based on a Fallback RA resource set information (FRI) indicating the one second RA resource set among the at least two second RA resource sets.

Abstract: The present disclosure relates to a method of transmitting a Medium Access Control (MAC) protocol data unit (PDU) by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of based on a first Medium Access Control (MAC) control element (CE) being triggered, transmitting, on a data uplink (UL) grant to a network, information indicating an amount of the first MAC CE to be transmitted; receiving a control UL grant from the network; constructing a MAC protocol data unit (PDU) including the first MAC CE; and transmitting the MAC PDU using the control UL grant.

Abstract: An Integrated Access and Backhaul (IAB) node configured with a first Backhaul Adaptation Protocol (BAP) address related to a first donor IAB node and a second BAP address related to a second donor IAB node in a wireless communication system. Techniques include receiving a packet including a destination BAP address and a path identifier (ID). Based on the packet being received through the second link and the destination BAP address not matching the second BAP address, determining whether the destination BAP address and the path ID of the packet match at least one entry of a configured rewriting table. Based on the destination BAP address and the path ID of the packet matching the at least one entry, rewriting a header of the packet by setting the destination BAP address and the path ID according to the at least one entry, and transmitting the packet to a next hop node.
