1. A method for wireless communication by a first base station (BS), the method comprising:
determining, at the first BS, a remote interference to at least one or more second BSs, based on a first reference signal (RS) from a second BS, the first RS indicating a first potential interference from the first BS to the second BS; and
transmitting from the first BS, a second RS, wherein the second RS is a remote interference management RS (RIM-RS), to indicate information about second potential remote interference to the one or more second BSs from the first BS, wherein the second 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).
