What is the use of EVENT A1 in LTE?

+1 vote

Why Enb need such a measurement report where UE reports about the serving cell better than threshold?
Is Enb has to do anything with transmission power of UE?

The LTE Event A1 is triggered when the serving cell becomes better than a threshold. The event is triggered when the following condition is true:

MEAsserv - Hyst > Threshold 

Triggering of the event is subsequently cancelled when the following condition is true:

MEAsserv + Hyst < Threshold

The hysteresis can be configured with a value between 0 and 30 dB.

A1 Event

As per my knowledge there is impact of UE power in serving cell measurement but dont know the detail :(

I was going through the measurement configuration sends from eNodeB to UE in RRC Connection Reconfiguration message.
I saw that multiple events have been defined and are used. Couple of parameters are considered to detect entering and leaving condition of an event for example event A1. Now I have a question "Threshold and Hys values are same for all the cell or it may different". Does the standard define the value of all these parameters or network operator defines ? If network operator does then what are points to derive these values ?

Unlike for A3 and A5 events, for A6 event frequency offset is not considered while evaluating entering and leaving condition. Can anyone please explain this particular case ?

Can someone please explain, why UE is configured for the event A1?
I am want to know the purpose of behind it.
