The present invention relates to a method for measuring radio channel quality in a radio communication system. In the method a modulated signal is received over a communication channel. The modulated signal has been modulated by using modulation parameters. A decoder decodes () the modulated signal and forms decoded data. The decoder creates () a decoder performance indicator (PS) that depends on the decoded data. Then a radio channel quality indicator (RCQI) is created, the radio channel quality indicator being essentially independent of the modulation parameters.

Method for measuring radio channel quality and related equipment

This method for receiving a data stream transmitted over several radiofrequency channels each with a different frequency, comprises scanning the bandwidth to identify available radiofrequency channels, determining a quality indicator for each available radiofrequency channel and selecting a channel for receiving the data stream depending upon said quality indicators. The method further comprises determining a refreshing period for the quality indicator of each available channel and weighting every determined refreshing period depending on the value of the quality indicator of the currently received channel.
