Per-span PDCCH monitoring enhancements

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE), the instructions when executed configure the one or more processors to:

• send, to a 5th generation NodeB (gNB), UE capability information indicating a capacity to monitor a physical downlink control channel (PDCCH), the UE capability information indicating whether the UE has a carrier aggregation capability over multiple downlink cells, the UE capability information further indicating a maximum number of PDCCH candidates that the UE is configured to monitor per span when the UE is configured for carrier aggregation operation over multiple downlink cells;
• receive, from the gNB based on the UE capability information, a radio resource control (RRC) message comprising an indication to monitor a PDCCH on a serving cell for the maximum number of PDCCH candidates, the indication comprising one of a per slot indication and a per span indication;
• and
• expect to be configured, by the RRC message, common search space (CSS) sets that result in not more than corresponding total, or per scheduled cell, numbers of monitored PDCCH candidates and non-overlapped CCEs per slot or per span that exceed the corresponding maximum numbers per slot or per span, respectively.
