Physical uplink control channel resource determining method, terminal, and network-side device

Abstract

This application discloses a physical uplink control channel resource determining method, a terminal, and a network-side device, and pertains to the field of wireless communications technologies. A physical uplink control channel resource determining method in embodiments of this application is provided, including: receiving, by a terminal, system information, where the system information includes a first index, and the first index is used to indicate one target PUCCH resource set in multiple PUCCH resource sets that are predefined; obtaining, by the terminal, a first target parameter configured for the target PUCCH resource set; and determining, by the terminal based on the first target parameter and a predefined configuration parameter for the target PUCCH resource set, a target physical uplink control channel (PUCCH) resource for use before radio resource control establishment.
