Transmitter and Receiver, Serializer and Deserializer and Methods for Transmitting and Receiving, Serializing and Deserializing

An apparatus for transmitting a plurality of data streams, wherein the apparatus comprises:

• a scheduling unit for selecting a data stream out of the plurality of data streams as a selected data stream, and
• a transmission unit for transmitting the selected data stream,
• wherein the scheduling unit is configured to select the selected data stream out of the plurality of data streams depending on scheduling information and depending on a counter value, wherein the scheduling information comprises a plurality of scheduling elements, wherein each of the plurality of scheduling elements comprises selection information and data stream information,
• wherein for each scheduling element of the plurality of scheduling elements, a data stream of the plurality of data streams is assigned to said scheduling element, wherein the data stream information of said scheduling element is data stream information for the data stream being assigned to said scheduling element,
• wherein for each scheduling element of the plurality of scheduling elements, a selection criterion is either fulfilled or not fulfilled depending on the selection information of said scheduling element and depending on the counter value,
• wherein, depending on an order of the plurality of scheduling elements of the scheduling information, the scheduling unit is configured to select, as the selected data stream, a data stream out of the plurality of selected data streams, which is assigned to a selection element of the plurality of selection elements, for which the selection criterion is fulfilled,
• wherein, to select the selected data stream, the scheduling unit is configured to determine for at least one scheduling element of the plurality of scheduling elements of the scheduling information or for each scheduling element of the plurality of scheduling elements of the scheduling information, whether or not the selection criterion is fulfilled, depending on the counter value and depending on the selection information of said scheduling element.
