Abstract:
1. An apparatus in a first base station for dynamic, distributed coordination of physical-layer transmission parameters between the first base station and a plurality of neighboring base stations in a cellular telecommunication network, the apparatus comprising: a processor that controls the operation of the apparatus when executing computer program instructions stored on a non-transitory memory device, wherein the processor controls the following components of the apparatus: wherein the processor also controls the interface unit to send the local parameter settings and the supplementary information to the neighboring base stations on the neighbor list; wherein the processor controls the components of the apparatus to iteratively perform the following exchange multiple times with the neighboring base stations in the neighbor list until a convergence condition is satisfied: wherein the first base station and the neighboring base stations utilize the supplementary information to determine which base stations are dominant downlink interferers and to select parameter settings for optimal performance of the entire network; and wherein each neighboring base station includes its own apparatus performing the same functions as the apparatus in the first base station.
