Uplink control channel resource definition and mapping to user equipment

A method for wireless communication at a user equipment (UE), comprising:

• identifying a plurality of indices for a plurality of corresponding physical uplink control channel (PUCCH) resources, each index of the plurality of indices associated with a respective PUCCH resource that has a corresponding starting symbol and duration;
• identifying a PUCCH resource mapping rule based at least in part on an amount of uplink control information for a PUCCH transmission;
• determining, from among the plurality of PUCCH resources, a PUCCH resource for the PUCCH transmission based at least in part on using the PUCCH resource mapping rule to identify a corresponding index of the plurality of indices;
• and
• transmitting the PUCCH transmission via the PUCCH resource.
