Relaxed control channel element and blind decoding overbooking and dropping for new radio ultra-reliable low-latency communications

A method for wireless communications at a network device, comprising:

• identifying a fixed span within a slot in which a user equipment (UE) is to apply a dropping rule, wherein the dropping rule indicates that the UE is to drop control channel element monitoring occasions or downlink control channel candidates in accordance with the dropping rule;
• configuring one or more common search spaces within spans of the slot for communication with the UE such that at least the fixed span within the slot includes a common search space;
• and
• indicating, to the UE, a common search space configuration in accordance with the configuring.

A method for wireless communications at a network device, comprising:

• identifying a maximum number of spans per slot in which a user equipment (UE) is to apply a dropping rule, wherein the dropping rule indicates that the UE is to drop control channel element monitoring occasions or downlink control channel candidates in accordance with the dropping rule;
• configuring one or more common search spaces within spans of a slot for communication with the UE such that a number of spans within the slot that include a common search space is less than or equal to the maximum number of spans per slot;
• and
• indicating, to the UE, a common search space configuration in accordance with the configuring.
