Retransmission mode signaling in a wireless communication system

A method for determining a retransmission mode of a retransmission protocol for data transmissions provided to a communication terminal, the method comprising the steps of:

• receiving a control message related to a plurality data transmissions, wherein the control message comprises a field indicating one of a plurality of codepoints,
• wherein the plurality of codepoints is divided into at least two subsets, each subset of codepoints indicating a respective retransmission mode for the plurality of data transmissions indicated by the control message, and
• determining the retransmission mode of the retransmission protocol based on codepoint signalled in said field of the control message.

A communication terminal for use in a mobile communication system, the communication terminal comprising:

• a receiver for receiving a control message related to a plurality data transmissions, wherein the control message comprises a field indicating one of a plurality of codepoints, wherein the plurality of codepoints is divided into at least two subsets, each subset of codepoints indicating a respective retransmission mode for the plurality of data transmissions indicated by the control message,
• wherein the receiver is further adapted to receive said data transmissions using a retransmission protocol, and
• a processing unit for determining the retransmission mode of the retransmission protocol based on codepoint signalled in said field of the control message.

A base station for use in a mobile communication system, the base station comprising:

• a processing unit for generating a control message, the control message comprising a field indicating one of a plurality of codepoints, wherein the plurality of codepoints is divided into at least two subsets, each subset of codepoints indicating a respective retransmission mode for a plurality of data transmissions indicated by the control message, and
• a transmitter for transmitting the control message using a retransmission protocol and for transmitting said plurality data transmissions to a communication terminal.
