Abstract

The invention relates to a method of transmitting data packets between a transmitter and a receiver in predefined numbered slots, wherein the transmitter is provided for sending in one slot data of different streams multiplexed in a data packet to the receiver, wherein a STOP command is provided for at least one numbered slot, wherein the receiver is provided for sending the STOP command to the transmitter, wherein a mapping table is provided which maps each stop command of the numbered slots to a set of streams of the respective slot, wherein the stop command is provided for blocking a set of the streams of the respective slot according to the mapping table.

Claims

1. A method of transmitting data packets between a transmitter and a receiver in predefined numbered slots, wherein the transmitter is provided for sending in one slot data of different streams multiplexed in a data packet to the receiver, wherein a STOP command is provided for at least one numbered slot, wherein the receiver is provided for sending the STOP command to the transmitter, wherein a mapping table is provided which maps each STOP command of the numbered slots to a set of streams of the respective slot, wherein the STOP command is provided for blocking a set of the streams of the respective slot according to the mapping table.

2. A method as claimed in claim 1, wherein the transmitter and the receiver are provided with the mapping table by means of a configuration message.

3. A method as claimed in claim 1, wherein the receiver, once it has sent a STOP command to block a set of streams, starts a timer assigned to this set and, once the timer has stopped running, sends a further STOP command in so far as the set of streams to be blocked are still to be blocked.

4. A terminal for receiving data from a transmitter in predefined numbered slots, wherein the transmitter is provided for sending in one slot data of different streams multiplexed in a data packet to the receiver, wherein a STOP command is provided for at least one numbered slot, wherein the terminal is provided for sending the STOP command to the transmitter, wherein a mapping table is provided which maps each stop command of the numbered slots to a set of streams of the respective slot, wherein the stop command is provided for blocking a set of the streams of the respective slot according to the mapping table.

5. A system comprising a transmitter and a receiver wherein data packets can be transmitted in predefined numbered slots between the transmitter and the receiver, wherein the transmitter is provided for sending in one slot data of different streams multiplexed in a data packet to the receiver, wherein a STOP command is provided for at least one numbered slot, wherein the receiver is provided for sending the STOP command to the transmitter, wherein a mapping table is provided which maps each stop command of the numbered slots to a set of streams of the respective slot, wherein the stop command is provided for blocking a set of the streams of the respective slot according to the mapping table.

6. A system as claimed in claim 5, wherein the transmitter is a base station and the receiver is a mobile station of a wireless or cellular telecommunications network.

7. A system as claimed in claim 5, wherein the slot numbers are given by the HARQ process numbers of the High Speed Downlink Shared Channel of a Universal Mobile Telecommunications System (UMTS).

8. A system as claimed in claim 5, wherein one of the bit combinations of the Channel Quality Indication of the downlink Time Transmission Interval of the Universal Mobile Telecommunications System (UMTS) is used for the signalling of the STOP command.

9. A system as claimed in claim 5, wherein the receiver is connectable to an electronic device via an air interface, in particular via a Bluetooth Interface or via a Infrared Interface.
