Channel Quality Indicator

Figure: Channel Quality Indicator (Click to enlarge)

In case of HSDPA a channel quality indicator is send back from the mobile station to the network side (Node B). This channel quality indicator (CQI) is based on pilot channel measurements with a granularity of 30 discrete steps. These values can be used on the network side to decide about the applied modulation and coding scheme for the corresponding mobile (adaptive MCS). It can also be used for the scheduling algorithms (e.g. serve mobiles with the best channels first). The following example map shows very good CQI (>20) in LOS areas, and poor CQI in difficult areas.
