Abstract
A user apparatus communicating with a first base station and a second base station in a communication system which supports carrier aggregation is provided. The user apparatus includes a measurement unit configured to measure a timing gap between a reception timing of a first radio signal received from the first base station and a reception timing of a second radio signal received from the second base station; and a transmission unit configured to transmit the information indicating the timing gap measured by the measurement unit to the first base station or the second base station.
Claims18
A user apparatus in a communication system, the user apparatus comprising:
- a transmission unit that communicates with a first base station and a second base station using carrier aggregation;
- and
- a measurement unit configured to measure a timing gap between a reception timing of a first radio signal received from the first base station and a reception timing of a second radio signal received from the second base station,
- wherein the transmission unit transmits information indicating the timing gap to the first base station or the second base station, and
- wherein the information indicating the timing gap includes a discretized value or an index number corresponding to a predetermined time gap.
A base station comprising:
- a reception unit that receives, from a user apparatus information indicating a timing gap between a reception timing of a first radio signal transmitted from the base station and a reception timing of a second radio signal transmitted from another base station different from the base station;
- and
- a control unit that controls the user apparatus based on the information indicating the timing gap,
- wherein the information indicating the timing gap includes a discretized value or an index number corresponding to a predetermined time gap, and
- wherein the user apparatus communicates with the base station and the another base station using carrier aggregation.
