'I PDCCH Processing Component 650-b Search Space Component 652 Control RB Component 654 Irregular Grant Component 656 Fast Control Channel Signal Component 658 PDCCH Signaling Component 650-a Search Space Component 651 Control RB Component 653 Irregular Grant Component 655 Fast Control Channel Signal Component 657 130 11 11 11 O 00 O 1-1 (57) : The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Chan- nel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.
