Abstract: "MOBILE COMMUNICATION SYSTEM, SOURCE BASE STATION, TARGET BASE STATION AND USER EQUIPMENT" Provided is a communication system that can be normally and efficiently operated in the case where existing carriers and new carrier types coexist. A base station device and a communication terminal device are configured to perform communication in cells of legacy carriers LC I to LC3 being existing carriers. When the base station device starts operating new carrier types NCT! and NCT2, the NCTI and NCT2 are associated with legacy carriers belonging to the same frequency band. For example, the NCT2 is , associated with the LC2 or the LC3 and is not associated with the LC!. The legacy carriers LC! to LC3 associated with the NCTl and the NCT2 notify the communication terminal device of the infration on the NCT! and NCT2. This allows the communication terminal device to communicate with the NCTI and the NCT2.
1. A mobile communication system in which a communication partner that communicates with a user equipment is changed from a source base station to a target base station,
wherein a transmission configuration for transmitting, to the user equipment, a reference signal to be measured by the user equipment is notified from the source base station to the target base station.
2: The mobile communication system as claimed in claim 1, wherein the transmission configuration is a configuration related to a frequency of performing transmission of the reference signal.
3: The mobile communication system as claimed in claim 2, wherein the transmission configuration is a configuration in which the frequency of performing transmission of the reference signal is less frequently than normal.
4. The mobile communication system as claimed in claim 1, wherein the source base station notifies the target base station of the presence or absence of the transmission configuration.
5. The mobile communication system as claimed in claim 1, wherein the source base station notifies the target base station of a frequency of a carrier for transmitting the reference signal to the user equipment.
6. The mobile communication system as claimed in claim 1, wherein the source base station requests the target base station to change a partner that communicates with the user equipment to the target base station.
7. A source base station that is a communication partner of a user equipment before a
base station that communicates with the user equipment is changed to a target base station,
wherein the source base station notifies the target base station of a transmission configuration for transmitting, to the user equipment, a reference signal to be measured by the user equipment.
8. A target base station that is a communication partner of a user equipment after a base
station that communicates with the user equipment is changed from a source base station,
wherein the target base station receives, from the source base station, a transmission configuration for transmitting, to the user equipment, a reference signal to be measured by the user equipment.
9. A user equipment that changes a communication partner form a source base station
to a target base station,
wherein a transmission configuration for transmitting, from the source base station, a reference signal to be measured is notified from the source base station to the target base station, and
the user equipment receives and measures, according to the transmission configuration, the reference signal transmitted from the target base station.
