1. A method for wireless communication by a first base station (BS), the method comprising:
transmitting a remote interference mitigation reference signal (RIM-RS) to indicate potential interference to one or more second BSs, wherein the RIM-RS is different than a synchronization signal/physical broadcast channel (SS/PBCH) block, a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), a positioning reference signal (PRS), a physical random access channel (PRACH), and a sounding reference signal (SRS); and
receiving remote interference information from at least one of the one or more second BSs in response to the RIM-RS.
