Abstract
The present invention is designed so that mismatches in the recognition of TPC command-accumulated values between a radio base station and a user terminal are resolved in a simple way. The user terminal of the present invention provides a user terminal that transmits uplink channels, and that has a receiving section that receives transmission power control (TPC) commands from each of a plurality of cells that are grouped, a control section that controls the uplink channel transmission power of each of the multiple cells based on accumulated values of the TPC commands, and, when a reset condition is fulfilled in one of the multiple cells, the control section resets the accumulated values of all of the multiple cells.
