Abstract
The present application discloses a method in which a terminal controls a timing group in a wireless communication system. Specifically, the method is characterized by comprising: a step for measuring the difference between the downlink timing of a specific serving cell and a reference cell; and a step for transmitting, via a network, a message requesting the change of a timing group, if the specific serving cell belongs to the same timing group as the reference cell and the measured downlink timing difference is at least a threshold value, or if the specific serving cell belongs to a different timing group to the reference cell and the measured downlink timing difference is less than the threshold value.
