LTE/NR PCI Conflict , PCI Confusion,PCI Collision, Mod of PCIs- 3,4,6,30
Dear readers as per above snap its easy to say PCI confusion and Collision coming under PCI conflict and reaspective reasons that mentioned in snap . Each 5G/4G cell corresponds to a Physical Cell ID (PCI) and it is used to distinguish cells on the radio side. The PCI planning for 5G NR is very much similar to PCI planning for LTE and scrambling code planning for 3G UMTS. Bad or wrong planning can affect the synchronization procedure , demodulation, and handover signalling and degrade the network performs. PCI Planning should be simpler for NR compare to LTE because there are double as many PCIs available for allocation While Planning PCI , below things need to follow strictly 1. Nbr cell should not have same position of PSS 2. Nbr Cell can use same SSS position 3. Intra Cells of an eNB should not have same PCI in same carrier As PCI is derived from PSS and SSS so there should not be same position of PSS &SSS combination of cells on their different Antenna Port . For example fo
