Blind detection and control channel element monitoring limits in carrier aggregation

A system comprising a network, the network comprising a processing circuit configured to:

• receive, from a first user equipment (UE), a declaration of capabilities of the first UE;
• send, to the first UE, a first search space configuration for a first component carrier in a carrier aggregation scheme;
• send, to the first UE, a second search space configuration for a second component carrier in the carrier aggregation scheme,
• wherein:
• the first search space configuration comprises a first set of monitoring occasions, and
• the second search space configuration comprises a second set of monitoring occasions;
• determine an (X, Y) pair that is satisfied by both the first set of monitoring occasions and the second set of monitoring occasions, wherein the (X, Y) pair is a feature 3-5b capability supported by the first UE;
• determine a union of the first set of monitoring occasions and the second set of monitoring occasions;
• determine a span pattern based on the union;
• determine whether the (X, Y) pair is satisfied by the span pattern;
• and
• (i) implement a first control channel elements (CCE) limit if the (X, Y) pair is satisfied by the span pattern;
• or
• (ii) implement a second CCE limit different from the first CCE limit if the (X, Y) pair is not satisfied by the span pattern.
