Hi Experts,

Is there any significance of CORESET0-Search Space 0 in NSA?

CORESET might be either common or dedicated
CORESET0 is specific use case of Common Coreset, where SIB 1 message is broadcasted.

Each searchSpace doesn’t matter if common or UE specific … has a group/multiple of uEs that just belong to same Aggregation Level … right?

means different uEs with different aggregation levels will be belonged to different searchSpaces.

Hello Experts.

Is CORESET#0 mandatory for NSA?

If not, so how UE knows position for Common_search space location?

[sadanandk2]

Of course mandatory.

Thanks, but how after disable SIB1 in NSA, 5G NSA cell is working normally?

[RFSpecialist]

Because whole information from SIB1 comes in RRC reconfiguration to setup the NR NSA.

Check this: 5G_CommonSearchSpace_Type0_PDCCH

That is in pdcch_configSIB1 in MIB 5G

SIB1 is not mandatory in NSA, mandatory info is sent by RRC reconfig.

SIB1 used for ANR in NSA.
