Frequency resource mapping for physical uplink control channel/acknowledgement (PUCCH/ACK) and autonomous uplink (AUL) in new radio-unlicensed (NR-U)

An apparatus comprising:

• a processor configured to identify, based on whether an uplink communication signal is to be transmitted within a first transmission opportunity (TXOP) or outside a second TXOP, a first configuration from a plurality of configurations associated with resources in a plurality of subbands, wherein each of the plurality of configurations maps a set of bits in an uplink resource indicator to a different subset of the resources;
• and
• a transceiver configured to:
• communicate, with a wireless communication device, a subband priority configuration;
• communicate, with the wireless communication device, the uplink resource indicator associated with the uplink communication signal;
• and
• communicate, with the wireless communication device, the uplink communication signal using a first resource of the resources based on bit values of the uplink resource indicator, the subband priority configuration, and the first configuration.

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• code for causing a first wireless communication device to communicate, with a second wireless communication device, a subband priority configuration;
• code for causing the first wireless communication device to communicate, with the second wireless communication device, an uplink resource indicator associated with an uplink communication signal, the uplink resource indicator including a set of bits;
• code for causing the first wireless communication device to identify, based on whether the uplink communication signal is to be transmitted within a first transmission opportunity (TXOP) or outside a second TXOP, a first configuration from a plurality of configurations associated with resources in a plurality of subbands, wherein each of the plurality of configurations maps the set of bits in the uplink resource indicator to a different subset of the resources;
• and
• code for causing the first wireless communication device to communicate, with the second wireless communication device, the uplink communication signal using a first resource of the resources based on bit values of the uplink resource indicator, the subband priority configuration, and the first configuration.
