Abstract: A wireless communication system and, more particularly, a method and an apparatus therefor, the method including the steps of: triggering power headroom reporting at a first time point; determining power headroom (PH) information of a cell on the basis of actual transmission or a reference format, on the basis of an uplink (UL) scheduling status; and transmitting the PH information of the cell at a second time point, via a configured grant based physical uplink shared channel (PUSCH), wherein the UL scheduling status includes downlink control information reception from the first time point to a third time point which exists before the second time point, and a time interval between the third time point and the second time point is determined on the basis of a PUSCH processing time.

Abstract: The present invention relates to a method of performing a discontinuous reception (DRX) operation by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: monitoring a wake up-signal (WUS) periodically in WUS transmission opportunities; if the WUS is successfully detected in the WUS transmission opportunities and if the WUS indicates to wake up, monitoring a physical downlink control channel (PDCCH) during a first DRX ON duration; and if the WUS is not successfully detected in the WUS transmission opportunities, monitoring the PDCCH during a second DRX ON duration, wherein the second DRX ON duration is longer than the first DRX ON duration.

Abstract: A method for transmitting signals by a user equipment (UE) in a multi input multi output (MIMO) communication system is disclosed. The method comprises steps of receiving two or more MIMO layer configurations per bandwidth part (BWP); receiving a medium access control (MAC) control element (CE) indicating a first MIMO layer configuration for a downlink reception via a first BWP and a second MIMO layer configuration for an uplink transmission via a second BWP among the two or more MIMO layer configurations; and transmitting and receiving signals based on the first and second MIMO layer configurations.

Abstract: Provided is a method and device for selectively transmitting a secondary cell group (SCG) failure information message to one of a master node (MN) and a secondary node (SN) in a wireless communication system. A user equipment (UE) detects a failure related to an SCG, and selectively transmits an SCG failure information message to one of an MN and an SN according to a reason for the failure related to the SCG. For example, if the reason for the failure related to the SCG is associated with the size of a hybrid automatic repeat request (HARQ) buffer, the UE ma transmit the SCG failure information message to the SN.

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: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling of a prohibit timer to transmit a RRC message related to UE capability restriction in wireless communication system, the method comprising: transmitting a first UE Assistance Information message indicating temporary information related to UE capability, when the UE has overheating problem; starting a timer when the first UE Assistance Information message is transmitted; and transmitting a second UE Assistance Information message if temporary information related to UE capability in the second UE Assistance Information is changed from the temporary information related to UE capability in the first UE Assistance Information message while the timer is running. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station, or a network.
