Method and device for allocating multi transmission timing to at least one timing advance group in a wireless access system for supporting carrier aggregation
The present invention relates to methods of allocating a Timing Advance (TA) value used for at least one timing advance group in a wireless access system for supporting carrier aggregation (CA). According to one embodiment of the present invention, a method of adjusting transmission timing for at least one TA group in a wireless access system for supporting CA includes: receiving, by a terminal, a physical downlink control channel (PDCCH) signal including a reserved bit indicating at least one TA group; receiving a medium access control (MAC) message including at least one TA value corresponding to at least one TA group; and transmitting an uplink signal by applying a TA value corresponding to a TA group in the TA group that the reserved bit indicates. At this point, each of the at least one TA group may include at least one primary cell.
