There are disclosed a method, base station and computer-readable storage media for downlink power allocation in a wireless communication system. The method may comprise obtaining information on positions of user equipments in a cell; classifying the user equipments into cell-edge user equipments and non-cell-edge user equipments based on the obtained information on the positions of user equipments in the cell; and performing downlink power allocation by increasing power allocated to at least one of physical downlink control channels (PDCCH) for scheduled user equipments of the cell-edge user equipments and common reference signals with power borrowed from at least one of downlink common channels for scheduled user equipments of the non-cell-edge user equipments. With embodiments of the present disclosure, downlink transmit power can be allocated efficiently and thus cell downlink coverage may be increased at a low cost.
