Abstract
A user terminal includes a transmission section that transmits channels using a first cell and a second cell that belong to different cell groups, and a control section that, when a channel to be transmitted in the first cell and a channel to be transmitted in the second cell are same channels and channel transmission in the first cell overlaps at least partially in time with channel transmission in the second cell, preferentially allocates transmission power to one of the channel transmission in the first cell and the channel transmission in the second cell over the other.
Claims6
A user terminal that communicates with a radio base station, comprising:
- a transmission section that transmits channels using a first cell and a second cell that are different cells in which the user terminal applies Multiple Timing Advance (MTA);
- and
- a control section that, when a parameter for a plurality of power control modes on the first and second cells is received from the radio base station by higher layer signaling and when channel transmission of a physical channel to be transmitted in the first cell overlaps at least partially in time with channel transmission of the physical channel to be transmitted in the second cell, preferentially allocates transmission power to one of the channel transmission in the first cell and the channel transmission in the second cell over the other.
A radio communication method in a user terminal that communicates with a radio base station, comprising:
- transmitting channels using a first cell and a second cell that are different cells in which the user terminal applies Multiple Timing Advance (MTA);
- and
- when a parameter for a plurality of power control modes on the first and second cells is received from the radio base station by higher layer signaling and when channel transmission of a physical channel to be transmitted in the first cell overlaps at least partially in time with channel transmission of the physical channel to be transmitted in the second cell, preferentially allocates transmission power to one of the channel transmission in the first cell and the channel transmission in the second cell over the other in the transmitting.
