1. A method performed by a receiving network node for cross-link interference, CLI, mitigation, the method comprising:
receiving, from at least one sending network node, a time division duplex configuration for a plurality of slots of the at least one sending network node in a message listing the slots of the time division duplex configuration, each of the listed slots being identified by an index, the time division duplex configuration identifying:
at least one slot of the time division duplex configuration as either a fixed uplink slot for which all symbols are for uplink transmission or a fixed downlink slot for which all symbols are for downlink transmission; and
at least one slot of the time division duplex configuration as a flexible slot for which at least one symbol has an undefined transmission direction and the remaining symbols of the slot, if any, have a defined transmission direction which is either uplink or downlink;
adapting operations in a cell based on the received time division duplex configuration for mitigating CLI with the at least one sending network node.
