A system may include a base station central unit and a base station distributed unit. The base station central unit may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station central unit to send, to the base station distributed unit, an indication that a cell is associated with a first non-public network (NPN); and to send, to the base station distributed unit, a request for configuration of the cell for a wireless device that supports the first NPN. The base station distributed unit may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station distributed unit to receive the indication and the request for configuration of the cell.
