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.

Abstract: In the present disclosure, a first node performs buffer status reporting including information regarding a total amount of UL data. The first node determines the total amount of UL data for the buffer status reporting based on an amount of UL data for which the UL resources are actually allocated to the second node by the first node.

Abstract: A method and apparatus for a user equipment (UE) operating based on a DRX (Discontinuous Reception) configuration are disclosed. According to these, the UE receives a message including configuration or reconfiguration of DRX; and monitors a PDCCH (Physical Downlink Control Channel) during an active time according to the configuration or reconfiguration of DRX. Here, the active time includes a time period during a PDCCH indicating a new transmission has not been received after receiving the message including configuration or reconfiguration of DRX.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a buffer status reporting in dual connectivity, the method comprising: configuring a threshold value for a PDCP entity associated with a first MAC entity for a first eNB and a second MAC entity for a second eNB for a radio bearer; checking, by the PDCP entity, whether an amount of uplink data available for transmission in the PDCP entity is less than the threshold value; and indicating, by the PDCP entity, that the amount of uplink data available for transmission in the PDCP entity is ‘0’ to the second MAC entity, if the amount of uplink data available for transmission in the PDCP entity is less than the threshold value.

Abstract: The present invention relates to a method for performing a random access procedure by a user equipment in a wireless communication system. In particular, the method includes transmitting a first number of random access preambles; detecting a second number of random access responses corresponding to the first number of random access preambles; and transmitting an payload using one uplink grant for which a listen before talk (LBT) procedure is firstly successful among a second number of uplink grants included in the second number of random access responses.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing an adaptive bundling transmission in wireless communication system, the method comprising: generating a uplink (UL) data to be transmitted for an uplink grant of a Hybrid-ARQ (HARQ) process; performing a new HARQ transmission of the UL data with resetting a counter of the HARQ process, performing a HARQ retransmission of the UL data, if the new HARQ transmission of the UL data fails, wherein the counter is counted each time a HARQ transmission of the UL data fails, wherein if the counter is equal to or larger than a threshold, the HARQ retransmission of the UL data is performed with bundling transmission.

Abstract: The present invention relates to a method for performing retransmissions by a transmission end in a wireless communication system. In particular, the method includes the steps of: re-transmitting a data unit to a reception end; and increasing a retransmission counter associated with the data unit, when the retransmission counter associated with the data unit reaches to a max value, reporting a max retransmission indication to an upper layer and setting the retransmission counter associated with the data unit to zero.

Abstract: The present invention relates to a method for performing uplink transmissions by a transmission end in a wireless communication system. In particular, the method includes the steps of: receiving a dynamic uplink grant for a HARQ process from a reception end; and performing an uplink transmission scheduled by the dynamic uplink grant, wherein at least one uplink transmission on at least one configured uplink grant for the HARQ process after receiving the dynamic uplink grant before performing the uplink transmission scheduled by the dynamic uplink grant is skipped.
