Claim 7:
8. An apparatus for wireless communication, the apparatus comprising:
at least one processor; and
a memory coupled to the at least one processor, wherein the at least one processor is configured 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;
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.
