USER APPARATUS, BASE STATION, UPLINK TRANSMISSION POWER REPORTING METHOD AND PARAMETER NOTIFICATION METHOD

摘要

A user apparatus in a mobile communication system includes a first and second base station that perform communication with the user apparatus by inter-base station carrier aggregation. The user apparatus receives, from the first base station, a first detection parameter on uplink transmission power reporting set for a first cell group that is a cell group of the first base station. The user apparatus also receives a second detection parameter on uplink transmission power reporting set for a second cell group that is a cell group of the second base station. The user apparatus reports uplink transmission power information to one of or both of the first and second base station when detecting a report trigger of the uplink transmission power information in a cell group of the first and second cell group by a detection parameter of the first and second detection parameter.

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 dual connectivity, comprising:
a reception unit configured to receive, from the first base station, a first detection parameter, on uplink transmission power reporting, set for a first cell group that is a cell group of the first base station, and a second detection parameter, on uplink transmission power reporting, set for a second cell group that is a cell group of the second base station; and a report control unit configured to report uplink transmission power information to one of or both of the first base station and the second base station when detecting a report trigger of the uplink transmission power information in an activated cell in a cell group of the first cell group and the second cell group by a detection parameter of the first detection parameter and the second detection parameter.
