Document Type and Number:
Japanese Patent JP2015216440
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress the deterioration of an uplink throughput when a user terminal is connected to a plurality of radio base stations.SOLUTION: A user terminal (20), which is connected to a plurality of radio base stations (10) including a first radio base station and a second radio base station, includes: a transmitter unit (203) which transmits to each radio base station a plurality of types of uplink signals; and a control unit (401) which controls uplink signal transmission power on the basis of the priority of the uplink signals to each radio base station. For each uplink signal of an identical type, the control unit sets priority to the first radio base station to be higher than priority to the second radio base station.
