Claim 14:
15. A non-transitory computer-readable medium having instructions recorded thereon that, when enacted by one or more computer processors, cause the one or more computer processors to:
receive, by a user equipment (UE), a preemptive grant for preemptive communications with a serving base station during current communications on a shared communication channel, wherein the preemptive grant includes at least:
a sub-symbol offset for a beginning of the preemptive communications; and
a length of the preemptive communications;

identify, by the UE, within the preemptive grant, a dynamic sub-carrier spacing (SCS) change for the UE resulting in use of one or more mini-symbols contiguous to one or both of an initial boundary resource or an ending boundary resource of the preemptive communications;
determine, by the UE, whether to perform a listen before talk (LBT) procedure on the shared communication channel; and
participate, by the UE, in the preemptive communications according to the preemptive grant; and
return, by the UE, to a standard SCS for remaining communication resources granted for the preemptive communications.
