Outer gNB neighbour_list entries now only declare the serving cell nr_cellid. The code resolves that field with gpd instead of a fixed column index. Changes: - gnb_paramdef.h: remove unused NEIGHBOUR_CELL_PHYSICAL_ID from GNB_NEIGHBOUR_LIST_PARAM_LIST (keep NRCELLID only). - gnb_config.c: in fill_neighbour_cell_configuration, set nr_cell_id from gpd
