Hi.

For NR any network deploy RSRQ based reselection and handover?

Any issue seen with RSRQ?

Yes… we have deploy RSRP and RSRQ handover in network this will reduce ping pong handover and reducation in mute observed

Issue:
Only RSRP based, ping pong will observed due to high fading in Higher band TDD .

Only RSRQ, In this case UE will wait until RSRQ criteria meet condition can comes in network where single quality is good but coverage may degrade (there will be condition in live network where only stand alone side serving in particular area).

Benefit of using RSRP+RSRQ, UE will based on both coverage and quality so Decisions will be better resulting improvement in mute by decreasing ping pong handover due to fading in TDD layer).

For NR we don’t have option like RSRP and RSRQ in connected mode.

For idle mode if we define both threshold serving low p and threshold serving q in sib2 then UE will consider RSRQ based reselection only.
