A base station central unit transmits a first message to a base station distributed unit. The first message comprises first configuration parameters of a wireless device. The base station central unit receives a second message from the base station distributed unit indicating acknowledgement of the first message. The second message comprises second configuration parameters based on the first configuration parameters. The base station central unit transmits to the wireless device via the base station distributed unit, a third message comprising the second configuration parameters. The base station central unit receives from the wireless device via the base station distributed unit, a fourth message confirming at least one of the second configuration parameters. The base station central unit transmits to the base station distributed unit, a fifth message indicating that the wireless device successfully performed a reconfiguration procedure based on the second configuration parameters.
