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?

First part of your question is answered at below link:

Here is my thoughts for the second part:

At low SINR more and more robust modulation and coding scheme is used. This mean lower modulation scheme (lesser bits per symbol) and large number of the redundant bits. In LTE HARQ is used to transmit redundant information and at receiver the same is combined for successful decoding. Thus receiver is able to receive the data even with negative SINR.

I have basic handover related query. How source eNodeB get to know when it has to trigger handover required message ? I mean to ask, how a source eNodeB come to know the threshold values of RSRP or RSRQ or both (related to target eNodeB) , required to do a successful handover towards eNodeB ? Is it due to network planning ?
