METHOD AND COMMUNICATION SYSTEM FOR ESTIMATING THE DOWN-LINK FRAME ERASURE RATE FROM THE MEASUREMENTS OF UPLINK AND DOWNLINK CONNECTIONS

摘要

A method for determining a transmission frame - error rate (fer) in the transmission of transmission frames between at least a first station (bs) and at least one second station (ms) in a communication system with a plurality of stations (bs, ms),characterized by the,– that a reception quality (rxqual - ul) and a transmission frame - error rate (fer - ul) of a in the uplink (ul) of the second station (ms) to the first station (bs) transmitted signal is determined and are entered in a look-up table,– that a reception quality (rxqual - dl) of a in the downlink (dl) of the first station (bs) to the second station (ms) transmitted signal is determined and in the uplink (ul) to the first station (bs) is signalled, and– that the transmission frame - error rate in the downward direction (fer - dl) of the signaled reception quality in the downward direction (rxqual - dl) is determined by means of the look-up table.
