Abstract: A method and apparatus for supporting a random access channel (RACH)-less mobility with pre-allocated beams in a wireless communication system is provided. A user equipment (UE) receives a mobility command message which includes information on a pre-allocated UL resource for UL transmission with pre-allocated beams, synchronizes to a target cell, and performs the UL transmission to the target cell via the pre-allocated beams based on the pre-allocated UL resource for UL transmission to transmit a mobility complete message via a UL grant. If the UL transmission fails, the UE may perform RACH procedure.

Abstract: Provided are a method of estimating mobility state of UE and a device supporting the method. According to one embodiment of the present invention, the method includes: receiving information on neighbor cell from a serving cell, wherein the information informs to which group the neighbor cell belongs; performing cell change from the serving cell to the neighbor cell; when the neighbor cell belongs to a first group, counting the cell change; when the neighbor cell belongs to a second group, skipping counting the cell change; and reporting a number of counted cell change for estimating mobility state of the UE, wherein the first group and the second group are configured based on altitude of the UE.

Abstract: A method and apparatus for monitoring paging on unlicensed bands in a wireless communication system is provided. A wireless device calculates a first paging occasion (PO) based on its identifier (ID), receives information on timing of monitoring paging from a network, and monitors the first PO. When a discovery signal is not detected in the first PO, the wireless calculates a second PO based on the information on the timing of monitoring paging, not based on its ID, and monitors the second PO. The second PO is a PO associated with other wireless device, but not associated with the wireless device by the ID of the wireless device.

Abstract: Provided are a method for performing, by a user equipment (UE), a role change between a primary cell and a secondary cell in a wireless communication system, and an apparatus supporting the same. The method may include: receiving a configuration and a condition for triggering the role change between the primary cell and the secondary cell; configuring a source cell as the primary cell and a target cell as the secondary cell; determining whether or not the condition is satisfied; and when it is determined that the condition is satisfied, configuring the target cell as the primary cell and the source cell as the secondary cell based on the configuration.

Abstract: A method and apparatus for deprioritizing access on an unlicensed band based on user equipment (UE) preference in a wireless communication system is provided. A wireless device attempts to access a cell on an unlicensed frequency and starts a timer. When the timer expires, if the wireless device is a licensed preferred wireless device, the wireless device deprioritizes the unlicensed frequency. If the wireless device is an unlicensed preferred wireless device, the wireless device deprioritizes only the cell. The wireless device performs a cell reselection according to the de-prioritization.

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.
