Abstract
Methods and arrangements for adjusting timing of transmissions in a radio communication system in which aggregation of component carriers is employed are disclosed. A base station sends a first TA command applicable to a first component carrier to a user equipment. A need to maintain different uplink transmission timing for the first user equipment component carrier and second uplink component carrier is detected by the base station. The base station then sends a second TA command based on the detected need to maintain different uplink transmission timing. The second TA command is applicable to uplink transmissions on the first component carrier and/or the second component carrier. The user equipment adjusts uplink transmissions on the first component carrier and/or the second uplink component carrier based on the second timing advance command.
