Abstract:
1. A method 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 equipment, each of which transmits data on an uplink channel to said communication network entity over said radio interface, said method comprising the steps of: receiving, at a Node B, transmit power control commands on said uplink channel, from a user equipment; if there is a channel quality indicator available, comparing, at the Node B, said channel quality indicator measurements with a pre-defined threshold value; and, if said channel quality indicator measurements precedes said threshold value, calculating, at the Node B, a required downlink power and adjusting transmission power based on the calculated downlink power in order to obtain efficient radio resource utilization; otherwise, decoding, at the Node B, said received transmit power control commands and adjusting transmission power based on the decoded transmit power control commands in order to obtain efficient radio resource utilization.
