摘要： In a network (700, 800) with a plurality of cells (715, 815, 825), there may be interference couplings among the cells (715, 815, 825). This may be particularly true for heterogeneous networks (800). For radio resource scheduling in such network (700, 800), a semi-decentralized scheduling is proposed in which radio resource scheduling issue is reformulated as load scheduling issue. In the proposed semi-decentralized scheduling, portions of the total load or available headroom are centrally allocated to each local node (710, 810, 820) subject to the stability of the network (700, 800). At each local node (710, 810, 820), radio resources are granted to users (740, 840) of that local node (710, 810, 820) subject to the portion of the load or headroom allocated to that local node (710, 810, 820).
