METHOD BY WHICH TERMINAL DETERMINES UPLINK CONTROL CHANNEL RESOURCE IN WIRELESS COMMUNICATION SYSTEM, AND TERMINAL USING METHOD

Document Type and Number:

WIPO Patent Application WO/2019/083249

Kind Code:

A1

Abstract:

The present invention provides a method by which a terminal performs a physical uplink control channel (PUCCH) transmission in a wireless communication system, the method: determining a particular set of PUCCH resources among a plurality of sets of PUCCH resources on the basis of the largest uplink control information (UCI) bit number and an actual UCI bit number transmitted by the terminal with respect to each of the plurality of sets of PUCCH resources; receiving, from a base station, downlink control information (DCI) including information on a particular PUCCH resource; and performing the PUCCH transmission on the basis of the particular PUCCH resource included in the determined particular set of PUCCH resources.
