Abstract
A method for packet data transmission in a communication system is disclosed, where the packet data includes a first type of data packet and at least one alternative second type of data packet. According to the method, quality modifications of a transmission channel used as a connection between a data source and data sinks are detected and, according to the detected quality modification, a data packet type of a successive data packet to be transmitted via the transmission channel is selected.

A method for packet data transmission in a Bluetooth radio communication system, wherein the packet data comprises a first data packet type and at least one different second data packet type, comprising the steps of:
- recording changes in a quality of a transmission channel used for a connection between a first data source and a data sink;
- depending on the changes in the quality recorded, switching back and forth between the first data packet type and the at least one different second data packet type for subsequent data packets to be sent over the transmission channel, wherein
- a) the first data packet type is a DM5 packet, and
- b) the at least one different second data packet type is a DH5 packet, and
- wherein the step of switching back and forth between the first data packet type and the at least one different second data packet type comprises determining if the first data source is a master data source or a slave data source, and if the first data source is the master, then the switch to another data packet type is made immediately, and if the first data source is the slave, then the switch to another data packet type is made after requesting to a master of the slave the data packet type switch.
A method for packet data transmission in a Bluetooth radio communication system, wherein the packet data comprises a DM5 data packet type and at least one DH5 data packet type, the method comprising the steps of:
- recording changes in a quality of a transmission channel used for a connection between a first data source and a data sink, wherein the changes in quality are defined by a first threshold and a second threshold;
- selecting a subsequent data packet type to be a DM5 data packet type if the change in the quality reaches the first threshold;
- selecting a subsequent data packet type to be a DH5 data packet type if the change in the quality reaches the second threshold;
- and
- switching back and forth between the DM5 data packet type and the at least one DH5 data packet type based on the changes in the quality of the transmission channel, wherein the step of switching back and forth between the DM5 packet type and the at least one DH5 data packet type comprises determining if the first data source is a master data source or a slave data source, and if the first data source is the master, then the switch to another data packet type is made immediately, and if the first data source is the slave, then the switch to another data packet type is made after requesting to a master of the slave the data packet type switch.
