The present invention is applicable to the field of radio communication technologies, and provides a carrier allocation method, a user equipment, and a base station. The method comprises: acquiring, by a base station, a carrier hopping pattern; sending, by the base station to a user equipment UE, carrier configuration information, where the carrier configuration information comprises information about activating carrier hopping and/or the carrier hopping pattern, the carrier hopping pattern presents a carrier set used by a user equipment in at least one time unit, and the carrier set comprises at least one carrier; and sending, by the base station, a signal to the UE and/or receiving a signal from the UE according to the carrier hopping pattern.
