Base Station and Method Thereof

摘要

There is provided a base station (BS) (1000) and a method at the BS that is capable of enhancing network capacity with low transmission power in a radio network. The method comprises serving a cell with one or more first carriers. The method further comprises serving a hot-spot within the cell with one or more beam-formed second carriers, wherein the first and second carriers share a total transmission power for serving the cell. Beam-forming based hot-spot carriers can efficiently save transmission power and contribute to the total power utilization efficiency. The base station (1000) thus can meet the capacity enhancement requirement with low transmission power.
