PCI cell planning in 5G

One question: for PCI cell planning in 5G we get lot of conditions: should not be any PCI mod3, mod4 and mod6 colisson for cells of same site or important neighbors.
This is quite a challening condition.
Anyone aware how to solve it?
mod3 is for PDSCH DMRS, mod4 is for PBCH DMRS and mod6 is for TRS

Do we need to link PCI planning with DMRS mod?

In LTE we have mod 3, 6 PCI planning options.
For 5G, need to check impact of PCI and DMRS?

If we get interference on DMRS nothing can be decoded.

Mod 3 is for PSS not for PDSCH DMRS.

here is PCI planning rule.
