Abstract

The present specification provides a method for transmitting multiple uplink control information (UCI) on a physical uplink control channel (PUCCH) in a wireless communication system. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, control information related to PUCCH resources for transmitting the multiple UCI, wherein the control information includes information related to a number of REs of the PUCCH resources, information related to a modulation order, and information related to a configured maximum code rate; determining a PUCCH resource for transmitting the multiple UCI by comparing a value obtained by multiplying the configured maximum code rate and the modulation order by the number of REs corresponding to the PUCCH resources indexed in ascending order with a size of a payload for the multiple UCI; and transmitting, to the base station, the multiple UCI on the determined PUCCH resource.
