Need clarity on following items:
1. What is the use of "UE selected plmn" information for an eNodeB ?
2. Is the ECGI/TAI constructed based on the primary plmn (PLMN broadcasted in 0th index in SIB1 ) or based on the UE selected PLMN ?

In LTE FDD mode, eNodeB has two separate earfcn values, one is downlink earfcn and second one for uplink earfcn. Does an UE detect all the possible earfcns(1.4 Mhz, 5 Mhz, 10Mhz etc) of a frequency band ?

I have two cells having same operating frequency with different PCI's. After applying measurement config I got neighbor cell measurement report and then I am triggering for ECGI request but I am not getting ECGI report.

So I am guessing there is problem in configuration of DRX which is used to give proper idle period to UE.

Please help if any one have experience on this.
