eNodeB will send uplink timing advance to UE periodically. So whether UE also has to send PRACH periodically? If not then how eNodeB will calculate the uplink timing advance without receiving PRACH periodically?

Does UE sends measurement reports periodically or only event occurs?

If ENB configures some measurement event say A1,A2,A3 etc, take e.g A2 event threshhold as -100Dbm, and serving cell thrs crosses -100 then UE will send A2, after this event UE is still facing signal strength as -100dB over a long period, will UE sends second time A2 event or only once?
