This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for physical uplink control channel (PUCCH) resource configuration. In one aspect, a base station may schedule a user equipment (UE) for PUCCH transmission based on a time division orthogonal cover code (TD-OCC) or a set of TD-OCCs, a cyclic shift step size or a set of cyclic shift step sizes, a first symbol or a set of first symbols, or a cyclic shift set. The base station may distinguish communications from that UE based on the TD-OCC or set of TD-OCCs, the cyclic shift step size or set of cyclic shift step sizes, the first symbol or set of first symbols, or the cyclic shift set.
