1. A method for operating a cell, performed by a network node, the method comprising:
transmitting a frame comprising a set of slots;
receiving Channel State Information, CSI, reports at least indicative of interference measured by a user equipment using the set of slots;
estimating a transmission direction pattern of an adjacent cell relative to a transmission direction pattern of the cell based on the received CSI reports;
transmitting a signal to the user equipment based on the estimated transmission direction pattern of the adjacent cell;
calculating a statistical measure of interference levels, of each slot of the set of slots, using the CSI reports and previously received historical CSI reports;
the transmission direction pattern of the adjacent cell estimated using the statistical measure;
determining that the statistical measure is stationary; and
selecting only one slot out of the corresponding slots having the stationary statistical measure for later CSI reporting instances.
