Abstract:
A method and arrangement in a radio communication network for predicting channel quality on a downlink channel. A radio base station (RBS) transmits data on the downlink channel to one or more user equipments (UEs), each of which transmits a channel quality indicator to the RBS on an uplink channel. The RBS derives a needed downlink transmission power from the received channel quality indicator, and predicts a channel quality for a next downlink transmission based on the received channel quality indicator and the derived downlink transmission power.
