Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
1 . A user terminal that controls uplink transmission power, comprising: a receiving section that receives transmission power control (TPC) commands; and a control section that controls uplink transmission power based on an accumulated value of the TPC commands, wherein, when subframes in a radio frame are divided into a plurality of subframe sets, the control section calculates the accumulated value of the TPC commands on a per subframe set basis, and controls resetting of the accumulated…
