Priority handling-based cell reselection method in wireless communication system and apparatus for supporting the method

摘要

Provided is a cell reselection method performed by a terminal in a wireless communication system. The method comprises acquiring information indicating that the lowest priority is to be applied to a specific frequency, applying the lowest priority to the specific frequency and operating a cell reselection, applying the highest priority to the specific frequency upon sensing a specific type cell during the operation, and performing a cell reselection based on the applied lowest priority or highest priority.

主权项

1. A cell reselection method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, by the UE from a network, information indicating to apply a lowest priority to a current frequency, wherein the information is received through a radio resource control (RRC) connection reject message, wherein a timer is used to indicate a period for which the current frequency is to be de-prioritised to the lowest priority, wherein the timer is started upon receiving the RRC connection reject message, and the de-prioritisation of the current frequency is stopped at an expiry of the timer; and performing, by the UE, a cell reselection with selectively applying the lowest priority to the current frequency or the highest priority to the current frequency, wherein the lowest priority is applied to the current frequency based on the received information or the highest priority is applied to the current frequency if the UE detects a specific type of cell.
