Abstract: A first radio station (100) monitors, either continuously or intermittently, a channel for an indication of a transmitted data packet and measures the quality of the channel. The first radio station (100) transmits indications of the measured quality and when the measured quality falls below a quality threshold, it reduces the proportion of time spent monitoring the channel by introducing or increasing time periods when no monitoring takes place, and subsequently increases the time spent monitoring when the quality recovers. A second radio station (200) transmits data packets to the first radio station (100) and receives the indications of measured channel quality. When the measured quality falls below the quality threshold, the second station reduces the proportion of time spent transmitting the data packets to the first radio station (100) by introducing or increasing time periods between transmitted the data packets.
