The invention provides a method, which comprises the following steps of: counting the number of average cell-edge users of each cell and the requirements of the average cell-edge users on occupied resources to determine the time-frequency resource amount used for BR-OFDMA of each cell by combining message interaction among a plurality of cells, and then allocating the same time-frequency resourceused for the BR-OFDMA for the plurality of cells; negotiating to determine a scrambling code of each cell, generating a corresponding long scrambling code according to the sequence number of the scrambling code, and then setting a long scrambling code sequence and the BR-OFDMA time-frequency resource into a mapping relation; and determining a block replication factor according to the number of the cells and the interference among the cells, and determining that the block number of the time-frequency resource allocated for the plurality of cells is integral multiple of the block replication factor. The invention also provides a device and a base station. Obviously, the method, the device and the base station solve the problem of coordinated allocation of the time-frequency resource among the plurality of cells.
