Method and Device for the Configuration of a Transmission Link

A method for data transmission at a receiver-side data transmission unit comprising the acts of:

• receiving at the receiver-side data transmission unit a first portion of a data packet from a transmitter-side data transmission unit via a communication channel;
• determining at the receiver-side data transmission unit an availability of the communication channel on the basis of
• parameters of the communication channel measured during the data packet first portion receiving act, and
• estimated parameters of the communication channel for a portion of the data packet not yet transmitted from the transmitter-side data transmission unit to the receiver-side data transmission unit within an available remainder of a maximum permissible data transmission time;
• transmitting from the receiver-side data transmission unit an availability indicator based on the determined communication channel availability to the transmitter-side data transmission unit;
• and
• if the availability indicator indicates the communication channel is available, receiving the portion of the data packet not yet transmitted from the transmitter-side data transmission unit at the receiver-side data transmission unit via the communication channel.

A transmitter-side data transmission unit configured to transmit a data packet from a real-time application via a communication channel to a receiver-side data transmission unit, comprising:

• at least one transmitter-side data output/reception unit;
• and
• at least one availability determination unit configured to determine an availability of the communication channel between the at least one transmitter-side data output/reception unit and at least one receiver-side data transmission unit,
• wherein the at least one transmitter-side data output/reception unit is configured to
• receive a data transmission request for a data packet from the real-time application operatively connected to the transmitter-side data transmission unit;
• transmit a first portion of the data packet from the transmitter-side data transmission unit to the receiver-side data transmission unit via the communication channel;
• receive at the transmitter-side data transmission unit an availability indicator for the communication channel from the receiver-side data transmission unit;
• and
• if the at least one availability determination unit determines the communication channel is available,
• configure a portion of the data packet not yet transmitted for transmission within an available remainder of a maximum permissible data transmission time determined by the real-time application for the data packet, and
• transmit the portion of the data packet not yet transmitted from the at least one data output/reception unit to the receiver-side data transmission unit via the communication channel.

A receiver-side data transmission unit configured to receive a data packet from a real-time application transmitted by a transmitter-side data transmission unit via a communication channel, comprising:

• at least one receiver-side data output/reception unit;
• and
• at least one availability determination unit configured to determine an availability of the communication channel between the at least one receiver-side data output/reception unit and at least one transmitter-side data transmission unit based on,
• wherein
• the at least one receiver-side data output/reception unit is configured to
• receive a first portion of a data packet from the at least one transmitter-side data transmission unit via the communication channel;
• transmit an availability indicator based on the determined communication channel availability to the transmitter-side data transmission unit, the availability indicator being determined by the at least one availability determination unit based on parameters of the communication channel measured during the receiving of the first portion of the data packet and estimated parameters of the communication channel for a portion of the data packet not yet transmitted from the transmitter-side data transmission unit to the receiver-side data transmission unit within an available remainder of a maximum permissible data transmission time, and
• if the availability indicator indicates the communication channel is available, receiving the portion of the data packet not yet transmitted from the transmitter-side data transmission unit via the communication channel.
