Abstract
The radio network controller estimates respective attenuation ratios of radio signals received by a terminal from transmitters of an active set. It commands at least some of the transmitters of the active set to transmit to the terminal with respective powers such that the difference pi-pj between the respective transmission powers pi and pj of two transmitters i and j is substantially proportional towhere Li and Lj designate the attenuation ratios estimated for the transmitters i and j, respectively.
