Abstract: A method and apparatus for performing an uplink (UL) transmission with pre-allocated beams in a wireless communication system is provided. A user equipment (UE) receives a connection release message from a network in a first state. The connection release message includes information on a pre-allocated UL resource for UL transmission with pre-allocated beams. The UE enters a second sate from the first state, selects a cell, and performs the UL transmission to the cell in the second state via the pre-allocated beams based on the pre-configured UL resource for UL transmission when a data is available for transmission. The first state may be a radio resource control (RRC) connected state, and the second state may be an RRC inactive state and/or an RRC idle state.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a SPS activation in multiple SPS resources in wireless communication system, the method comprising: receiving an activation command for a first set of Semi-Persistent Scheduling (SPS) resources from a network, wherein a second set of SPS resources which is already activated on the UE; activating the first set of SPS resources and deactivating the second set of SPS resources based on the activation command for the first set of SPS resources; and transmitting a SPS confirmation Medium Access Control (MAC) Control Element (CE) which indicates that the UE successfully deactivates the second set of SPS resources and activates the first set of SPS resources, in a response to the activation command for the first set of SPS resources.

Abstract: A method for processing downlink (DL) signals by a user equipment (UE) in a wireless communication system is disclosed. Especially, the UE is configured not to transmit a Hybrid Automatic Repeat and request (HARQ) feedback for the DL HARQ process. The method comprises steps of upon a first Physical downlink Control Channel (PDCCH) for the DL HARQ process is detected, starting a timer for monitoring subsequent PDCCHs related to retransmission of the DL HARQ process, without transmitting the HARQ feedback; and monitoring subsequent PDCCHs related to retransmission of the DL HARQ process while the timer is running.

Abstract: In the present invention, service data units (SDUs) are delivered from a first layer to a second layer out-of-order irrespective of sequence numbers (SNs) of the SDUs. The second layer deciphers the SDUs in the order of reception from the first layer irrespective of the SNs. The second layer may reorders the deciphered SDUs in the order of the SNs, and delivers them to an upper layer in sequence.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a random access procedure in wireless communication system, the method comprising: starting a timer when a Msg3 for a RA procedure is transmitted to a base station; monitoring a Physical Downlink Control Channel (PDCCH) while the timer is running; and stopping the timer if the PDCCH including uplink resource for the retransmission of the Msg3 is received

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.
