Does ECGI is reported in measurement report only when ENB gives the PCI for which ECGI to be reported?

I have gone through the measurement config/ report messages.I found that in meas report UE can send PCI, RSRP, RSRQ, CGI report at a time.

Will UE will send CGI report also at the same time or UE will send only when ENB request UE for the ECGI with the Report ECGI by giving pci ?

As i understand, UE reads SIB5 after reading paging in idle mode. Why RRC reconfig is required at this time ?

how it is possible to decode the signals when the UE measures a negative SINR?

Can you, please explain what happens for the common channels? The PSS/SSS and PBCH have a fix position in time-frequency domain so in the area between the sectors we will have those REs (resource elements) and RBs (resource block) that are allocated to them that will interfere.
Also, can you explain how it is possible to decode the signals when the UE measures a negative SINR?
