Does Intra Freq eNB has same Pcell ID?

Question

i see few scenario where mobility info has target cell id as same as pcell id? Why this is sent by eNB?

Answer 1

Due to the construction of PCIs, the number of PCIs are limited to 504. Because of the large amount of cells in the LTE
network, the PCIs needs to be reused and several cells will share the same PCI. It creates pci collision & confusion.
so proper pci planning is required
