A PCI collision occurs between two intra-frequency cells that use an identical PCI. In this case, UEs in the overlapping area of the two cells cannot implement signal synchronization or decoding. Cleaning the PCIs is probably the most effective steps to improve RF performance. Good PCI assignment reduces call drops by enabling UE to clearly distinguish one cell from another

If possible then how the HARQ resource grid will be calculated. NR and LTE have different resource grid allocation how can we report HARQ of one cell to another cell in Dual connectivity.
