1. A method of communication at a wireless communication device, the method comprising:
receiving, from a network entity, a first indication of a scheduled uplink transmission for the wireless communication device on an unlicensed radio frequency spectrum, wherein the first indication specifies at least one scheduled interlace of a plurality of interlaces and at least one set of scheduled resource blocks of a plurality of sets of resource blocks;
receiving a cancelation indication from the network entity, wherein the cancelation indication identifies the at least one scheduled interlace, the at least one set of scheduled resource blocks, or the at least one scheduled interlace and the at least one set of scheduled resource blocks;
performing a bit mapping operation to identify, from the cancelation indication: at least one canceled interlace, at least one canceled resource block, or any combination thereof, wherein the bit mapping operation uses a formula that prioritizes the plurality of sets of resource blocks over the plurality of interlaces by first allocating bits of a plurality of bits to resource blocks and if there are remaining bits of the plurality of bits by allocating bits to interlaces; and
canceling the scheduled uplink transmission upon receiving the cancelation indication.
