1. A method performed by a wireless device with respect to a cellular network, the method comprising:
making radio signal measurements with respect to individual cells of the cellular network;
determining from the radio signal measurements that a plurality of cells is available for selection as a camping cell;
determining that the plurality of cells includes all cells from one or more multi-cell configurations mutually supported by the cellular network and the wireless device for serving the wireless device in multi-connectivity, wherein each multi-cell configuration represented in the plurality of cells is referred to as a possible multi-cell configuration and each cell belonging to one of the one or more possible multi-cell configurations is referred to as a multi-connectivity cell;
incorporating multi-cell prioritizations associated with the one or more possible multi-cell configurations into a ranking of the plurality of cells, to generate a biased ranking of the plurality of cells that biases camping cell selection by the wireless device towards multi-connectivity cell selection;
selecting, based on the biased ranking, one cell from among the plurality of cells as a camping cell; and
camping on the selected cell while the wireless device is in the dormant state.
