Abstract: A method for allocating resources by a transmission end in a wireless communication system is disclosed. The method includes steps of receiving an uplink grant for first and second logical channels; generating a data unit including data from the first and second logical channels based on the uplink grant; and transmitting the data unit to a network, wherein generating the data unit comprises: allocating the resources indicated by the uplink grant to first and second logical channels having positive token values by amount of corresponding prioritized bit rates (PBRs) with decrementing corresponding token values of each logical channel by amount of allocated resources; if a token value of the first logical channel is greater than 0, allocating remaining resources to the first logical channel until the token value of the first logical channel becomes zero; and if a token value of the second logical channel is greater than 0, allocating remaining resources to the second logical channel until the token value of the second logical channel becomes zero.

Abstract: A method and apparatus for discarding data among associated transmission buffers in a wireless communication system is provided. A wireless device generates a first data packet and a second data packet, and performs a random access (RA) procedure based on the first data packet. When the RA procedure based on the first data packet fails, the wireless device discards the first data packet, and continues the RA procedure based on the second data packet. A media access control (MAC) layer indicates a radio resource control (RRC) layer that the RA procedure based on the second data packet is performed.

Abstract: A transmitting device of the present invention submits, from a packet data convergence protocol (PDCP) entity configured with a PDCP duplication function, a PDCP protocol data unit (PDU) (duplicated PDCP PDU 1) to a lower layer and starts a prohibit timer for the duplicated PDCP PDU 1. The transmitting device submits, from the PDCP entity, the same PDCP PDU (duplicated PDCP PDU 2) to the lower layer if the prohibit timer expires. The transmitting device transmit the duplicated PDCP PDU 1 and the duplicated PDCP PDU 2.

Abstract: The present invention relates to a method of transmitting uplink (UL) data by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: upon transmitting the UL data based on a configured grant (CG) configuration related to a Hybrid-ARQ (HARQ) process, starting a first timer related to the HARQ process and a second timer related to the HARQ process; and performing retransmission of the UL data based on the HARQ process, wherein an UL resource on which the retransmission is performed is determined based on whether a UL resource of the CG configuration is configured or not between an expiration time point of the first timer and an expiration time point of the second timer.

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.
