Abstract

Claims (20)

1 . A terminal comprising:

a processor that multiplexes first uplink control information having a first priority and second uplink control information having a second priority lower than the first priority on an uplink control channel; and

a transmitter that transmits the first uplink control information and the second uplink control information using the uplink control channel, wherein

the processor determines that a number of resource blocks, in a frequency domain, related to the uplink control channel is a minimum number of resource blocks, so that a condition is satisfied, and

the condition is defined based on a number of bits of the first uplink control information, a number of bits of the second uplink control information, a code rate of the first uplink control information, and a code rate of the second uplink control information.

2 . The terminal according to claim 1 , wherein

the processor determines that a number of resource blocks related to the uplink control channel is the minimum number of resource blocks, so that the condition is satisfied when format of the uplink control channel is at least one of an uplink control channel format 2 or an uplink control channel format 3 .

3 . The terminal according to claim 1 , wherein

the condition is defined based on a number of error detection bits of the first uplink control information, and a number of error detection bits of the second uplink control information.

4 . A radio communication system, comprising:

a terminal and a base station, wherein

the terminal comprises a processor that multiplexes first uplink control information having a first priority and second uplink control information having a second priority lower than the first priority on an uplink control channel;

the base station comprises a receiver that receives the first uplink control information and the second uplink control information using the uplink control channel;

the processor determines that a number of resource blocks, in a frequency domain, related to the uplink control channel is a minimum number of resource blocks, so that a condition is satisfied; and

the condition is defined based on a number of bits of the first uplink control information, a number of bits of the second uplink control information, a code rate of the first uplink control information, and a code rate of the second uplink control information.

5 . A radio communication method, comprising:

multiplexing first uplink control information having a first priority and second uplink control information having a second priority lower than the first priority on an uplink control channel;

transmitting the first uplink control information and the second uplink control information using the uplink control channel; and

determining that a number of resource blocks, in a frequency domain, related to the uplink control channel is a minimum number of resource blocks, so that a condition is satisfied, wherein

the condition is defined based on a number of bits of the first uplink control information, a number of bits of the second uplink control information, a code rate of the first uplink control information, and a code rate of the second uplink control information.
