This is too early.

Agre, too early.
Why to measure them so early?
10 for us.

Same 10 for us as well.

Serving cell RSRP threshold controlling whether or not the UE is required to perform measurements of intra-frequency, inter-frequency and inter-RAT neighboring cells.

Just want to update per NR:
Specified in TS 138 331 - V15.2.1:

In RRC reconfiguration, there is S-measureconfig:

4> if s-MeasureConfig is set to ssb-RSRP and the NR SpCell RSRP based on SS/PBCH block, after layer 3 filtering, is lower than ssb-RSRP,or

5> if the measObject is associated to NR and the rsType is set to ssb:

6> if reportQuantityRsIndexes and maxNrofRSIndexesToReport for the associated reportConfig

are configured:

7> derive layer 3 beam measurements only based on SS/PBCH block for each measurement

quantity indicated in reportQuantityRsIndexes, as described in 5.5.3.3a;

6> derive cell measurement results based on SS/PBCH block for each trigger quantity and each

measurement quantity indicated in reportQuantityCell using parameters from the associated

measObject, as described in 5.5.3.3;

So it means serving cell is below 106 (-156+106=-50) then UE starts intra or inter freq measurement per SSB-RSRP value
