Abstract
The invention relates to a method for transmitting data between a transmitter and a receiver via a wireless data channel of a communication network (CN). The transmitter transmits data to the receiver, where the transmission includes at least one transmission parameter which is selected based on a first channel quality that is known to the transmitter. The receiver receives the data, and the receiver determines the first channel quality known to the transmitter from said data via the at least one used transmission parameter as well as a second, current channel quality via the quality of the received data; and the receiver compares the first channel quality with the second channel quality.

A method for transmitting data via a radio channel of a communication network between a transmitter and a receiver, wherein transmission parameters of the data are adjusted, comprising the steps of:
- determining at least one transmission parameter of the data transmitted to the receiver;
- determining a first channel quality, known to the transmitter, at the receiver, wherein the channel quality is based at least in part on the transmission parameter;
- determining a second channel quality from the quality of the received data;
- comparing the first and second channel qualities in the receiver, wherein, if the first and second channel qualities differ from each other by more than a predefined tolerance value, the receiver informs the transmitter of a deviation;
- and
- determining a further channel quality, on the basis of which the at least one transmission parameter is adjusted.
A communication station for transmitting data via a radio channel of a communication network wherein transmission parameters of the data are adjusted, comprising:
- means for determining at least one transmission parameter of the data transmitted to the receiver;
- means for determining a first channel quality, known to the transmitter, at the receiver, wherein the channel quality is based at least in part on the transmission parameter;
- means for determining a second channel quality from the quality of the received data;
- means for comparing the first and second channel qualities in the receiver, wherein, if the first and second channel qualities differ from each other by more than a predefined tolerance value, the receiver informs the transmitter of a deviation;
- and
- means for determining a further channel quality, on the basis of which the at least one transmission parameter is adjusted.
