1. An apparatus comprising:
a processor configured to cause a user equipment device (UE) to:
communicate with a cellular network according to a first downlink control information (DCI) mode;
receive first DCI from the cellular network according to the first DCI mode;
determine whether different higher layer indices are configured for two or more control resources sets (CORESETs);
select a second DCI mode, wherein the first DCI mode is different than the second DCI mode, based on the determination, wherein:
if different higher layer indices are configured for the two or more CORESETs, a multi-DCI mode is selected as the second DCI mode; or
otherwise, a single-DCI mode is selected as the second DCI mode; and
receive a DCI from the cellular network according to the second DCI mode.
