1. A base station, comprising:
a transceiver configured to wirelessly communicate with a user equipment (UE); and
a processor communicatively coupled to the transceiver and configured to:
generate a Downlink Channel Indicator (DCI), wherein the DCI comprises interlace resource allocation information for a Physical Uplink Control Channel (PUCCH) and a mapping between an Orthogonal Cover Code (OCC) index applied on an Uplink Control Information (UCI) symbol and a cyclic shift applied to a DeModulation Reference Signal (DMRS) symbol; and
transmit, using the transceiver, the DCI to the UE.
