Wireless communications systems and methods related to frequency resource mapping for uplink control channel communications and autonomous uplink communications in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device identifies a first configuration from a plurality of configurations for mapping an uplink resource indicator to resources in a plurality of subbands. The first wireless communication device communicates with a second wireless communication device, a subband priority configuration. The first wireless communication device communicates, with the second wireless communication device, the uplink resource indicator. The first wireless communication device communicates, with the second wireless communication device, an uplink communication signal using a first resource of the resources based on the uplink resource indicator, the subband priority configuration, and the first configuration.
