Abstract
A method of distributing information content to at least two user equipments includes: setting up a common downlink channel common to the at least two user equipments; setting up at least two uplink channels, each uplink channel being dedicated to a respective one of the at least two user equipments; delivering the information content to the at least two user equipments over the common downlink channel; and controlling transmission powers related to the common downlink channel and the at least two uplink channels in a closed-loop fashion. The closed-loop fashion power control includes: receiving from the at least two user equipments common downlink channel quality indications over the respective dedicated uplink channels; adjusting a transmission power in respect to the common downlink channel based on the common downlink channel quality indications received from the user equipments; evaluating a channel quality with respect to each of the at least two dedicated uplink channels; and based on the evaluation, sending to the at least two user equipments a transmission power control command over the common downlink channel.
