摘要： When a high SIR can be achieved for downlink data transmission, for example in a MIMO system, or when higher order modulation, such as 64 QAM, can be used, it is desired to measure the instantaneous downlink channel quality indicator (CQI), and report the measured CQI to the network using the same number of bits as when a lower SIR can be achieved. In order to do this, a true CQI is derived based upon at least one network controlled parameter and a measured channel quality parameter; and the true CQI value is scaled to a new CQI value such that the new CQI will fall within a specified range of CQI values; so that the new CQI achieved by scaling the derived CQI value can be reported with every CQI value over the entire reporting range requiring the same number of bits.

摘要： 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.

摘要： The invention relates to a method and an arrangement for obtaining efficient radio resource utilization in a communication network comprising a communication network entity transmitting data on a downlink channel over a radio interface to one or more user equipments, each of which is transmitting data on an uplink channel to said communication network entity over said radio interface. The communication network entity receives transmit power control (TPC) commands on said uplink channel and, further, monitors a channel quality indicator (CQI) on said uplink channel from said user equipment in order to obtain channel quality indicator measurements. If there is a channel quality indicator available, the communication network entity calculates a required downlink power. Otherwise, the communication network entity decodes said received transmit power control commands. Thereafter said transmission power is adjusted either based on the calculated downlink power or based on the decoded transmit power control commands in order to obtain efficient radio resource utilization.
