1. A network node for enabling mitigation of remote interference from another network node to communications between the network node and a wireless device (WD), the network node comprising processing circuitry configured to:
generate an initialization seed as a function of a time counter t and a scrambling identifier NID, the initialization seed computed by linearly combining, in a modulo 2 sense, a function of only the time counter t and a function of only the scrambling identifier NID, such that bits dependent on t and bits dependent on NID are placed on separate parts of a bit field of the initialization seed; and
generate a remote interference mitigation reference signal (RIM-RS) sequence based at least in part on the initialization seed.
