  abstract =     "In this paper, we address the capacity and coverage
                 optimisation (CCO) problem for LTE networks by means of
                 self-organising network (SON) techniques. A novel
                 hybrid two-layer optimisation framework is proposed to
                 enhance the network capacity and coverage, where on the
                 top layer a network entity of eCoordinator is
                 implemented to ensure overall network coverage by
                 optimising the antenna tilt and capacity-coverage
                 weight of each cell in a centralised manner, and on the
                 bottom layer individual eNB optimises cell-specific
                 capacity and coverage by tuning its pilot power in a
                 distributed manner. A heuristic algorithm is developed
                 for the eCoordinator operation at large time
                 granularity and the Genetic Programming (GP) approach
                 is exploited for the eNB operation at small time
                 granularity, for the purpose of tracking overall
                 network performance as well as adapting to network
                 dynamics. Our simulation results have demonstrated the
                 usefulness of the proposed algorithms by enhancing
                 network capacity and coverage performance under various
                 system requirements.",
