In some aspects, a user equipment (UE) may determine an offset value to be used to determine reference uplink resources associated with uplink cancellation indications; receive an uplink cancellation indication; and cancel an uplink communication in a set of reference uplink resources, wherein the set of reference uplink resources are determined based at least in part on the offset value and a time domain resource in which the uplink cancellation indication is received. Numerous other aspects are provided. ## Claims ### Claim 1 A method of wireless communication performed by a user equipment (UE), comprising: determining an offset value to be used to determine reference uplink resources associated with uplink cancellation indications;
