A method of operation of a network node to adjust uplink coverage for one or more cells in a cellular communications network, comprising: determining (100, 206, 300) that there is a need to adjust uplink beam transformations for one or more cells of a plurality of cells in a cellular communications network, wherein, for each cell of the one or more cells, the uplink beam transformation for the cell is a transformation of received uplink signals for the cell from an antenna domain to a beam domain, wherein determining (100, 206, 300) that there is a need to adjust the uplink beam transformations for the one or more cells comprises: evaluating a mismatch between an uplink coverage of the one or more cells and a downlink coverage of the one or more cells, and determining that there is a need to adjust the uplink beam transformations for the one or more cells if the mismatch between the uplink coverage of the one or more cells and the downlink coverage of the one or more cells is more than a predefined threshold; and upon determining that there is a need to adjust the uplink beam transformations for the one or more cells: determining (102, 208, 302) new uplink beam transformations for the one or more cells; and applying (104, 208, 302) the new uplink beam transformations for the one or more cells, wherein evaluating the mismatch between the uplink coverage of the one or more cells and the downlink coverage of the one or more cells comprises evaluating the mismatch between the uplink coverage of the one or more cells and the downlink coverage of the one or more cells in response to a change in downlink cell shaping for at least one of the one or more cells. determining (100, 206, 300) that there is a need to adjust uplink beam transformations for one or more cells of a plurality of cells in a cellular communications network, wherein, for each cell of the one or more cells, the uplink beam transformation for the cell is a transformation of received uplink signals for the cell from an antenna domain to a beam domain, wherein determining (100, 206, 300) that there is a need to adjust the uplink beam transformations for the one or more cells comprises: evaluating a mismatch between an uplink coverage of the one or more cells and a downlink coverage of the one or more cells, and determining that there is a need to adjust the uplink beam transformations for the one or more cells if the mismatch between the uplink coverage of the one or more cells and the downlink coverage of the one or more cells is more than a predefined threshold; and evaluating a mismatch between an uplink coverage of the one or more cells and a downlink coverage of the one or more cells, and determining that there is a need to adjust the uplink beam transformations for the one or more cells if the mismatch between the uplink coverage of the one or more cells and the downlink coverage of the one or more cells is more than a predefined threshold; and upon determining that there is a need to adjust the uplink beam transformations for the one or more cells: determining (102, 208, 302) new uplink beam transformations for the one or more cells; and applying (104, 208, 302) the new uplink beam transformations for the one or more cells, determining (102, 208, 302) new uplink beam transformations for the one or more cells; and applying (104, 208, 302) the new uplink beam transformations for the one or more cells, wherein evaluating the mismatch between the uplink coverage of the one or more cells and the downlink coverage of the one or more cells comprises evaluating the mismatch between the uplink coverage of the one or more cells and the downlink coverage of the one or more cells in response to a change in downlink cell shaping for at least one of the one or more cells.
