mapping the PUCCH resource indicator to a first offset;
determining a second offset based on a position of the received downlink control channel normalized by a value;
determining an index of the DMRS antenna port associated with the downlink control channel;
determining a third offset based on the determined index of the DMRS antenna port;
determining, based on the first, second, and third offsets, a first index identifying a first allocated PUCCH resource;
determining a second index identifying a second allocated PUCCH resource, the second index having a value that is equal to the first index plus a constant; and
