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.
