Search Space

The term search space describes a set of CCEs that a UE monitors. The UE can

decode only the control information on a PDCCH/CORESET that is transmitted over

CCEs within the search space this UE monitors.

A physical downlink control channel PDCCH consists of one or more control-channel

elements (CCEs), where their number is defined by the "Aggregation level".

The following parameters influence the way the search space is defined:

●

If Restrict to Search Space > "On", you define the search space by selecting the

aggregation level and the number of a particular candidate. The available can-

didates are defined as a combination aggregation level and maximum number of

candidates per aggregation level.

See:

– "Scheduling > CORESET > Payload" > Aggregation Level

– "Scheduling > CORESET > Payload" > Candidate

– "Scheduling > CORESET > General" > Aggregation Level and Max Candidates

The CCE start index CCE Index is selected automatically so that the CCE is within

the search space.

●

If Restrict to Search Space > "Off", you define the search space manually, by

setting the CCE start index, see CCE Index.
