Abstract
A user terminal includes a receiver that receives, from a radio base station, indication information to indicate whether or not uplink signals of a plurality of user terminals are non-orthogonal-multiplexed; a processor that switches between transmission power control methods based on the indication information; and a transmitter that transmits an uplink signal by using a switched transmission power control method.
Claims4
A user terminal comprising:
- a receiver that receives, from a radio base station:
- indication information to indicate whether or not uplink signals of a plurality of user terminals are non-orthogonal-multiplexed;
- and
- transmission power determining information that is used to determine transmission power of the uplink signal;
- a processor that:
- switches between transmission power control methods based on the indication information;
- and
- determines transmission power of the uplink signal based on the indication information and the transmission power determining information,
- wherein, when the indication information indicates that the uplink signals of the plurality of user terminals are non-orthogonal-multiplexed, the transmission power determining information is a given threshold for a channel state between the user terminal and the radio base station, and
- determines the transmission power based on a comparison result of the channel state and the given threshold;
- and
- a transmitter that transmits to the base station an uplink signal with the transmission power determined by using a switched transmission power control method.
