Describe the procedure of PCI planning
Plan the PCI in the live network
PCI: Physical Cell ID, is used to generate scrambling code to identify different cells.
PCI determines Reference Signal position in frequency domain.
It is advised to distribute PCIs in adjacent cells such that Reference Signals does not occupy same subcarrier position.
Therefore cell can have up to 5 different neighbors without interfering in frequency domain, i.e., Modulo6 problem.
Physical Cell ID = 0 R R

RS position is based on Physical Cell ID (Physical Cell ID mod 6)
Physical Cell ID = 8 R R

However LTE is usually implemented in 2x2, where the other antenna reference signals are positioned in between first antenna, therefore Modulo6, becomes Modulo3 problem.
