Abstract
Official abstract text for this publication.
A user equipment in a radio communication system including the user equipment and a base station, including: an uplink transmission power information calculation unit configured to calculate uplink transmission power information of a serving cell using a parameter that may be changed dynamically; and a signal transmission unit configured to include, in control information in which the uplink transmission power information is set, identification information for identifying a parameter used for calculation of the uplink transmission power information, and to transmit the control information in which the identification information is included to the base station.
First claim
Opening claim text (preview).
The invention claimed is: 1. A terminal comprising: a processor that calculates a power headroom that is not based on an actual transmission using an index of a reference signal used for pathloss calculation; and a transmitter that generates control information in which the power headroom is set, and that transmits the control information to a base station, wherein the index is a specific index of a plurality of indexes configured from the base station. 2. The terminal according to claim 1 , wherein the processor calculates the power headroom that is not based on the actual transmission using an index of a parameter set and the index of the reference signal used for pathloss calculation. 3. A method executed by a terminal, the method comprising: calculating a power headroom that is not based on an actual transmission using an index of a reference signal used for pathloss calculation; generating control information in which the power headroom is set; and transmitting the control information to a base station, wherein the index is a specific index of a plurality of indexes configured from the base station. 4. The method according to claim 3 , wherein the terminal calculates the power headroom that is not based on the actual transmission using an index of a parameter set and the index of the reference signal used for pathloss calculation.
