We know in SS block we have PSS SSS PBCH(DMRS in that)
According to 3gpp specs we measure SSRSRP which is defined as the RSRP from SSS .
Any specific reason for measuring SSS?

The center 20 RB carry the SSS. It also carries the reference signals. So, the UE does not have to scan the entire NR bandwidths. Remember, NR supports bandwidths of upto 400MHz, and scanning this entire range will drain the UE's bandwidth.

Why not PSS and Why SSS for measuring this?
