1. A method of handling a remote interference (RI) between base stations of a time division duplex (TDD) network, the method comprising:
determining a set of radio resources for reference signals (RSs) for handling the RI by:
receiving a first flag parameter from an Operations And Management (OAM) function or node of the TDD network, the first flag parameter being indicative of whether receiving and/or transmitting of the RSs is restricted to the set or allowed in all radio resource occasions for the RSs in the TDD network; and
receiving a second flag parameter from an OAM function or node of the TDD network, the second flag parameter being indicative of at least one of the set and one or more rules or conditions for the determination of the set; and
handling the RI by transmitting one or more RSs using the radio resources of the determined set.
