Abstract: A method of a user equipment (UE) in a wireless communication system includes receiving resource allocation information related to a configured grant (CG)-based uplink transmission, and transmitting a CG physical uplink shared channel (CG PUSCH) based on the resource allocation information. CG uplink control information (CG UCI) is multiplexed on the CG PUSCH. The CG UCI and control information different from the CG UCI are jointly encoded and multiplexed in the CG PUSCH, based on the control information being multiplexed in the CG PUSCH. One of a beta offset for the CG UCI or a beta offset for the control information is applied to the joint encoding.

Abstract: A wireless communication system is disclosed. More particularly, disclosed herein are a method including receiving downlink scheduling information on a PDCCH, the downlink scheduling information comprising resource indication information (RI), selecting a first PUCCH resource set from among a plurality of PUCCH resource sets based on a size of the control information, and transmitting the control information using a PUCCH resource corresponding to the RI in the first PUCCH resource set, wherein, when a control information size supported by the first PUCCH resource set is less than or equal to X (>=1) bits, the PUCCH resource is determined using one of a first scheme and a second scheme, and wherein, when the control information size supported by the first PUCCH resource set is greater than X bits, the PUCCH resource is determined using only the second scheme, and an apparatus therefor.
