Abstract
A user apparatus in a mobile communication system includes: a unit configured to receive a downlink control signal using a frequency of a residing cell; and a unit configured to perform cell search using a frequency different from the frequency of the residing cell during an interval between reception timings of the downlink control signal in response to an occurrence of a predetermined event for different frequency measurement in the user apparatus or a base station apparatus. When the reception timing interval of the downlink control signal is not longer than the threshold reported from the base station apparatus, and when the predetermined event for different frequency measurement occurs in the user apparatus or the base station apparatus, different frequency measurement is performed in a cycle, different from the reception timing interval, reported from the base station apparatus.
