In one example, the method can include generating information according to a protocol for receipt by a mobile device, wherein the information is indicative of a defined transmission type for the mobile device and wherein the protocol employs demodulation reference signal patterns; and transmitting the information to the mobile device. In some embodiments, the protocol comprises a first protocol in which the information comprises a first message transmitted in a first set of resources to communicate to the mobile device a first downlink control information (DCI) format associated with a first transmission type, and wherein the protocol further comprises a second protocol in which the information comprises a second message transmitted in a second set of resources to communicate to the mobile device a second DCI format associated with a second transmission type.

An extension of the existing CAN FD data transmission protocol. The extension enables the use of the IPv6 protocol for the CAN bus. The CAN FD protocol is further developed in an incompatible way. One modification measure relates to the lengthening of the Data Field, which is positioned in the transmission frame after an Arbitration Field. An arbitrary number of bytes can be entered in the extended Data Field within a specified upper limit. Since the Data Field is transmitted at a higher bit rate field than the Arbitration Field, the data throughput is increased dramatically.
