1. A method in a user equipment (UE), comprising:
receiving, at the UE, a downlink control channel carrying a physical uplink control channel (PUCCH) resource indicator, wherein the downlink control channel is associated with a demodulation reference signal (DMRS) antenna port;
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
transmitting a PUCCH on the first allocated PUCCH resource using a first antenna port and on the second allocated PUCCH resource using a second antenna port.
