CHANNEL QUALITY PREDICTION IN HSDPA SYSTEMS

摘要

The invention relates to a method and an arrangement for predicting a channel quality on a downlink channel in a communication network comprising a communication network entity (15) transmitting data on said downlink channel over a radio interface to one or more user equipments (18), each of which is transmitting data on an uplink channel to said communication network entity (15) over said radio interface. A channel quality indicator value is received from the user equipment(s) on the uplink channel. A needed downlink transmission power is derived. A channel quality for the next data transmission on said downlink channel is predicted based on the received channel quality indicator value and the derived downlink transmission power.
