What are the tradeoffs for using RSRP and RSRQ as A1-A5 trigger quantity?

Hello LTE Experts.
What are the tradeoffs for using RSRP and RSRQ as A1-A5 trigger quantity?
Which is widely used ?

RSRQ is generally used in heavy traffic netwkork or carriers.
In lightly loaded network RSRP is used which keep almost fix traffic share among the carrier.
But with RSRQ, as traffic increases RSRQ triggered handover invreases due to degradation in RSRQ.

The majority of live networks use only RSRP.

UE can remain connected to the serving cell while the RSRQ becomes poor. This can lead to dropped calls on networks where the level of interference is relatively high. Levels of interference will increase as the network load increases over time. This increases the importance of enabling RSRQ triggered mobility procedures.

I’d also add that, RSRQ will likelyl increase the amount of HOs, so, maybe for voice services it may not be a good choice.

Right. We are using RSRQ based for data only, not for Voice.
