Physical downlink control channel monitoring for super slots
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a span pattern for a super slot that corresponds to a transmission time interval over multiple slots. The UE may monitor, within a span that is specified by the span pattern and that extends across a slot boundary in the super slot, physical downlink control channel candidates for downlink control information. Numerous other aspects are described.

18 . The UE of claim 14 , wherein the BD and CCE limit applies to only one slot of the super slot.
19 . The UE of claim 14 , wherein the one or more processors, to monitor the PDCCH candidates or non-overlapped CCEs, are configured to monitor in only one slot of the super slot, and wherein the BD and CCE limit applies to the only one slot.
20 . The UE of claim 19 , wherein the only one slot is a starting slot of the super slot.
21 . The UE of claim 19 , wherein the only one slot is an end slot of the super slot.
22 . The UE of claim 14 , wherein the indication specifies that the BD and CCE limit is to be equally split among all slots of the super slot.
