METHOD AND DEVICE FOR ALLOCATING MULTI TRANSMISSION TIMING TO AT LEAST ONE TIMING ADVANCE GROUP IN A WIRELESS ACCESS SYSTEM FOR SUPPORTING CARRIER AGGREGATION |
摘要 |
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), methods of adjusting a wireless frame transmission time by using the TA value, and devices for supporting same. 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 (i.e. a TA group indicator) 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 (i.e. a P cell). |
