Method of performing cell reselection procedure in wireless communication system

摘要

A method of performing a cell reselection procedure in a wireless communication system includes evaluating priorities of a serving cell and neighbor cells, each of which use different frequency bands, performing inter-frequency measurement on a neighbor cell which has a higher priority than the serving cell, performing the inter-frequency measurement on a neighbor cell which has an equal or lower priority than the serving cell, when a signal characteristic of the serving cell is less than a threshold, and performing cell reselection according to the priorities.

1. A method of performing a cell reselection procedure in a wireless communication system, the method performed by a user equipment (UE) and comprising:
receiving, from a network, priorities of a serving cell and neighbor cells, wherein a frequency band used by the serving cell is different from a frequency band used by one of the neighbor cells, wherein the priorities are received via system information from a base station; performing inter-frequency measurement on a neighbor cell which has a higher priority than the serving cell irrespective of signal measurement of the serving cell; performing the inter-frequency measurement on a neighbor cell which has an equal or lower priority than the serving cell, when a signal characteristic of the serving cell is less than a threshold; and performing cell reselection according to the priorities.
