Abstract: The present disclosure relates to a measurement handling in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system, the method comprises: receiving information for a validity timer from a network; starting the validity timer to be expired at a first expiration time point based on the information; while the validity timer is running, performing a measurement on one or more neighbor cells and performing cell reselections; determining a mobility state based on a number of the cell reselections; adjusting, based on the mobility state, the first expiration time point to a second expiration time point of the validity timer that is currently running; and stopping the measurement upon reaching the second expiration time point.

Abstract: The present disclosure relates to managing measurement results in wireless communications. According to an embodiment of the present disclosure, a method performed by wireless device in a wireless communication system, the method comprises: receiving, from a first cell, a first frequency list for a measurement comprising a specific frequency; performing a measurement on the specific frequency to obtain a measurement result for the specific frequency; receiving, from a second cell to which a cell reselection is performed, a second frequency list for a measurement; and upon identifying that the specific frequency is different from all frequencies included in the second frequency list, releasing the measurement result for the specific frequency.

Abstract: A method and apparatus for supporting a hybrid mode positioning scheme in a wireless communication system is provided. While using a first positioning mode, a user equipment (UE) receives information on a triggering condition for the positioning mode switch from a network, i.e. an evolved serving mobile location center (E-SMLC). The UE determines that the triggering condition is satisfied, and switches the positioning mode from the first positioning mode to a second positioning mode.

Abstract: Provided are a method of acquiring changed system information (SI) and a device supporting the method. According to one embodiment of the present invention, a method for acquiring changed SI in a wireless communication system includes: receiving a first SI message; receiving a notification of SI change; receiving an indication indicating a second SI message, which only contains system information blocks (SIBs) to be modified in the first SI message; and receiving the second SI message according to the indication.

Abstract: Various embodiments provide a method for transceiving a signal by a terminal and a base station in a wireless communication system and a device supporting same.

Abstract: Provided are a method of acquiring system information and a device supporting the method. According to one embodiment of the present invention, the method includes: acquiring first system information including information element (IE) at a first time point; and acquiring validity time information informs how long the IE has not been changed, wherein acquiring of second system information including the IE at a second time point is skipped based on the first time point and the validity time information.
