    Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently limiting a number of blind decoding attempts or control channel elements (CCEs) that a user equipment (UE) is configured to monitor to limit complexity at the UE. When a UE is configured to use blind decoding for monitoring CCEs in multiple spans in a slot for control information from a base station, the UE may be configured to perform dropping of blind decoding candidates or CCEs in a first temporal span in the slot. In other words, the UE may identify a dropping rule to drop CCE monitoring occasions or blind decoding attempts in excess of a maximum number of non-overlapping CCEs per span or a maximum number of blind decoding attempts per span, respectively, and the UE may apply the dropping rule to the first temporal span within the slot.

    Abstract: This disclosure provides systems, methods and apparatus where a user equipment (UE) may indicate different physical downlink control channel (PDCCH) monitoring capabilities (such as UE capabilities in terms of the number of control channel elements (CCEs), blind decodes (BDs), number of downlink control information (DCI) formats, etc.) per monitoring span or slot. For example, a UE may support a different number of CCEs per slot or a different number of DCIs per monitoring span for different service types (such as a different number of CCEs for enhanced mobile broadband (eMBB) and for ultra-reliable low latency communications (URLLC)). A UE may indicate different sets of PDCCH monitoring capabilities (such as sets of PDCCH monitoring capabilities for different service types, monitoring spans, slots, etc.). A base station may receive the indication of UE PDCCH monitoring capability information, and may configure the UE with one or more monitoring occasions accordingly.
