METHOD FOR TRANSMITTING AND RECEIVING UPLINK SIGNALS, AND APPARATUS THEREFOR

摘要

The present invention relates to a method for transmitting an uplink signal in a wireless communication system. The method includes the steps of: transmitting an uplink signal in a first uplink transmitting timing period determined on the basis of a first timing advance command received from a first serving cell; and, when a specific condition is satisfied, transmitting an uplink signal in a second uplink transmitting timing period determined on the basis of a second timing advance command.
