1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, information including parameters related to a maximum code rate, wherein each parameter related to the maximum code rate is respectively configured for a physical uplink control channel (PUCCH) format 2 and PUCCH format 3;
receiving, from the base station, information including parameters related to an additional maximum code rate, wherein each parameter related to the additional maximum code rate is respectively configured for the PUCCH format 2 and the PUCCH format 3;
based on (i) a PUCCH format corresponding to the PUCCH format 2 or the PUCCH format 3, (ii) a maximum code rate configured for the PUCCH format, and (iii) an additional maximum code rate configured for the PUCCH format, determining a first maximum code rate of a first uplink control information (UCI) with a first priority and a second maximum code rate of a second UCI with a second priority;
determining a minimum number of physical resource blocks (PRBs), MPB,minPUCCH, of the PUCCH format based on

OG Complex Work Unit Math
where r0 is the second maximum code rate of the second UCI, r1 the first maximum code rate of the first UC, OACE0 is a number of bits of the second UCI, OCRC0 is a number of bits of the CRC for the second UCI, OACE1 is a number of bits of the first UCI, OCRC1 is a number of bits of the CRC for the first UCI, Nsc,ctrlRB is a number of subcarriers, NsymbUCIPUCCH is a number of OFDM symbols, an Qm is a modulation order; and
based on the minimum number of PRBs of the PUCCH format, transmitting, to the base station, via a PUCCH using the PUCCH format, the first UCI with the first priority and the second UCI with the second priority.
