User apparatus and uplink transmission power information transmission method
First Claim
1. A user apparatus in a mobile communication system including a first base station and a second base station that perform communication with the user apparatus by inter-base station carrier aggregation, comprising:
- a transmission trigger detection unit configured to detect a transmission trigger for transmitting uplink transmission power information in the user apparatus to the first base station or to the second base station; and
an uplink transmission power information transmission unit configured to transmit the uplink transmission power information to the first base station or to the second base station based on a transmission trigger detected by the transmission trigger detection unit,wherein the transmission trigger detection unit detects, as the transmission trigger, that a first cell under the second base station is added in the user apparatus after a primary cell under the first base station is configured in the user apparatus.

12. An uplink transmission power information transmission method executed by a user apparatus in a mobile communication system including a first base station and a second base station that perform communication with the user apparatus by inter-base station carrier aggregation, comprising:
-
a transmission trigger detection step of detecting a transmission trigger for transmitting uplink transmission power information in the user apparatus to the first base station or to the second base station; and an uplink transmission power information transmission step of transmitting the uplink transmission power information to the first base station or to the second base station based on a transmission trigger detected by the transmission trigger detection step, wherein the transmission trigger detection step, further comprises detecting, as the transmission trigger, that a first cell under the second base station is added in the user apparatus after a primary cell under the first base station is configured in the user apparatus.
