PingPong Handover

Hello to the LTE experts.

I would like to ask a question.
I have a problem due to the ping-pong handover process.
The process of ping pong handover between the two sectors is running normally, but my question is why I find 4 dB difference between the two sectors with the same eNodeB even though I am in the same position when the ping pong handover process was done.

It’s because of radio conditions and propagation. Sectors Sidelobes are weaker then main lobes and signals may fluctuate. Difference in db may vary.

Thank you for your answer, what was meant here by radio condition?
Should some parameters be changed or is this a normal fluctuation?
