Abstract: A method and apparatus for a cell selection or a cell reselection considering a network slice in a wireless communication system is described. A wireless device configures multiple network slices. A wireless device receives a network slice information related to the multiple network slices. A wireless device establishes a PDU session for a specific service. A wireless device determines one or more frequencies that support the at least one network slice, used by the PDU session, from among the multiple network slices based on the frequency information. A wireless device performs a cell selection procedure and/or a cell reselection procedure based on the determined one or more frequencies.

Abstract: A method and apparatus for a secondary cell group (SCG) failure handling with a conditional primary secondary cell (PSCell) configuration in a wireless communication system is provided. A wireless device evaluates a conditional change of PSCell based on a mobility command for the conditional change of the PSCell. Upon detecting a failure on a secondary cell group (SCG), the wireless device stops evaluating the conditional change of the PSCell, and transmits, to the network, information on the failure on the SCG.

Abstract: A method and apparatus for handling of missing reference signal on unlicensed frequency in a wireless communication system is provided. The upper layer of the wireless device receives, from a lower layer of the wireless device, a first indication related to a first reference signal from a network, wherein the first indication is one of In-Sync (IS) indication or Out-of-Sync (OOS) indication. The upper layer of the wireless device starts a timer. The upper layer of the wireless device receives, from the lower layer of the wireless device, a second indication while the timer is running, wherein the second indication informs that a second reference signal from the network is missing. The upper layer of the wireless device increases a counter related to the first indication upon receiving the second indication.
