摘要： A method and an apparatus for scheduling transmissions of a plurality of cells in a wireless communications system including one or more base stations is provided. The method comprises providing a set of virtual channels to enable an intra-cell transmission orthogonal to another transmission within each cell of the plurality of cells and inter-cell transmissions orthogonal to other transmissions across a cluster of cells associated with the one or more base stations. The method further comprises exchanging signaling messages between two or more base stations to coordinate scheduling of the intra-cell transmission with the inter-cell transmissions for the cluster of cells. For optimizing a parameter associated with scheduling of a plurality of users from a cluster of cells in a wireless communication system, an optimal power level for the parameter of each active user may be searched to maximize an indication of system capacity of the wireless communication system. This enables a coordinated jointly scheduling of the users active in the cluster of cells based on the optimal power levels such that the total interference within the cluster may be minimized to maximize the system throughput/capacity.
