Claim 4:
5. A terminal device, comprising:
a processor, configured to determine a number of physical resource blocks (PRBs) for transmitting uplink control information (UCI);
wherein the UCI is transmitted by using a first physical uplink control channel (PUCCH) format, and the number MPRB,minPUCCH of PRBs for transmitting the UCI satisfies:
(OUCI+OCRC)≤MPRB,minPUCCH·Nsc,ctrlPRB·NsymbPUCCH·Qm·r,
and
(OUCI+OCRC)>(MPRB,minPUCCH−1)·Nsc,ctrlPRB·NsymbPUCCH·Qm·r, wherein OUCI represents a number of bits of the UCI, OCRC represents a number of bits of a CRC, Nsc,ctrlPRB represents a number of subcarriers for the first PUCCH format to transmit the UCI in one PRB divided by NSFPUCCH, NSFPUCCH represents a spreading factor of the first PUCCH format, NsymbPUCCH represents a number of time domain symbols for the first PUCCH format to transmit the UCI, Qm represents a modulation order, and r represents a maximum code rate corresponding to the first PUCCH format,
wherein the first PUCCH format is PUCCH format 2, PUCCH format 3 or PUCCH format 4.
