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

A physical uplink control channel resource determining method, comprising:

• sending, by a network-side device, system information to a terminal, wherein the system information comprises a first index, and the first index is used to indicate one target physical uplink control channel (PUCCH) resource set in multiple PUCCH resource sets that are predefined;
• and
• determining, by the network-side device based on a first target parameter configured for the target PUCCH resource set and a predefined configuration parameter for the target PUCCH resource set, a target PUCCH resource before a specific PUCCH resource is configured, wherein the first target parameter comprises one or more elements, and one element indicates one value of physical resource block (PRB) count corresponding to the target PUCCH resource set,
• wherein the method further comprises:
• in a case that └PUCCH/8┘=0, determining, by the network-side device, that a starting PRB index of a first hop in the target PUCCH resource is
