Abstract: The present disclosure relates to a cell reselection in wireless communications. According to an embodiment of the present disclosure, a method performed by a user equipment (UE) in a wireless communication system comprises: receiving, from a network, location information comprising a location point for each time point related to each of neighbor cells; determining a distance to each of the neighbor cells from the UE as a distance between the location point and the UE; selecting one or more cells including at least one of: i) a cell to which the distance from the UE is longest among a first set of the neighbor cells in a distance decreasing state; or ii) a cell to which the distance from the UE is shortest among a second set of the neighbor cells in a distance increasing state; and performing a cell reselection to a cell among the selected one or more cells. The distance decreasing state is a state in which the distance to the first set of the neighbor cells from the UE decreases by time. The distance increasing state is a state in which the distance to the second set of the neighbor cells from the UE increases by time.

Abstract: A method and apparatus for handling ephemeris information for a NTN cell in a wireless communication system is provided. A wireless device may receive, from a network, an ephemeris information related to a Non-Terrestrial Networks (NTN) cell. The wireless device may determine whether the ephemeris information is valid or not, based on whether the measurement on the NTN cell is able to be performed during the service time of the NTN cell. Based on determining that the ephemeris information is not valid, the wireless device may transmit, to the network, (1) information informing that the ephemeris information is not valid and (2) information on time at which the measurement on the NTN cell is able to be performed.
