Abstract
A user device communicates with base stations in a radio communication system including the base stations. The user device includes a receiver that receives a first downlink control signal transmitted from one of the base stations, a transmitter that transmits uplink signals using multiple antenna ports or multiple beams, and a controller that controls, for each subframe, transmission timing of the uplink signals transmitted using the multiple antenna ports or the multiple beams, based on the first downlink control signal.
