Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.

Abstract: Aspects of the present disclosure relate to wireless communication. In aspects, a base station may determine one or more signaling parameters to be used to transmit one or more reference signals that identify the base station in association with remote interference management, wherein the one or more signaling parameters include at least one of: multiple time periods in which the one or more reference signals are to be transmitted; one or more mini-bands, within one or more sub-bands, in which the one or more reference signals are to be transmitted; one or more scrambling codes, selected from a pool of scrambling codes, to be used to scramble the one or more reference signals; or a combination thereof. The base station may transmit the one or more reference signals using the one or more signaling parameters to identify the base station in association with remote interference management. Other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may detect interference, in a remote interference management (RIM) scenario, in a set of sub-bands of a plurality of sub-bands of a bandwidth portion. The base station may transmit, to identify the set of sub-bands in which interference is detected, a set of reference signals configured to indicate the set of sub-bands in which the interference is detected. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that at least one condition, of a plurality of conditions, is satisfied with regard to at least one other base station; and perform at least one remote interference management (RIM) operation, the at least one RIM operation selected based at least in part on the at least one condition. In some aspects, a base station may receive an indication regarding interference, the indication regarding interference indicating that at least one condition, of a plurality of conditions, is satisfied with regard to the base station or at least one other base station; and perform at least one RIM operation, the at least one RIM operation selected based at least in part on the at least one condition or the indication regarding interference. Numerous other aspects are provided.
