  • Patent number: 11005586
    Abstract: Certain aspects of the present disclosure provide techniques for reference signal monitoring and transmission for remote interference management. In some cases, an aggressor base station decides to monitor for reference signals (RSs) transmitted from at least one victim BS, for example, regardless of an amount of interference from at least one remote BS detected by the first base station and participating in a remote interference mitigation (RIM) process based on the monitored RS. In some cases, a first BS transmits reference signals (RSs) as part of a remote interference mitigation (RIM) process, in response to a determination that it is an aggressor BS whose downlink transmissions possibly interfere with reception of uplink transmissions by at least one remote BS, a victim BS whose reception of uplink transmissions are possibly interfered with by downlink transmissions from the at least one remote BS, or both an aggressor BS and a victim BS.
