Abstract: Certain aspects of the present disclosure provide techniques for remote interference mitigation between base stations using reference signals. Certain aspects provide a method for wireless communication by a first base station (BS). The method includes receiving a reference signal (RS) from a second BS. The method further includes performing interference measurement corresponding to interference from the second BS based on the RS being associated with the second BS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter may identify a set of resource elements on which to transmit a reference signal based at least in part on a numerology being used by the transmitter and at least one of a maximum system numerology or a minimum system numerology; and transmit the reference signal on the identified set of resource elements. In some aspects, a receiver may identify a set of resource elements from which to obtain a reference signal based at least in part on a numerology being used by the receiver and at least one of a maximum system numerology or a minimum system numerology; and obtain the reference signal from the identified set of resource elements.

Abstract: A method of wireless communication by a first user equipment (UE), includes receiving downlink signals from a network device. The method also includes receiving cross-link interference (CLI) to the downlink signals, the cross-link interference originating from a second UE. The method further includes receiving a configuration for a report of multiple differential cross-link interference metric values measured for multiple different cross-link interference resources and an absolute cross-link interference metric value measured for the different CLI resources. The method includes transmitting the report of the differential cross-link interference metric values measured for the different CLI resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration of a control region in a delay-Doppler domain. The UE may receive, from the base station, a physical downlink control channel (PDCCH) communication with orthogonal time frequency space (OTFS) precoding. The UE may decode the PDCCH communication with OTFS precoding based at least in part on the configuration of the control region in the delay-Doppler domain. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for prioritization schemes for prioritizing colliding cross-link interference (CLI) measurements scheduled via Layer-1 signaling and a downlink transmissions scheduled according to periodic configurations. In some examples, a user equipment (UE) may prioritize downlink transmissions over CLI measurements. A UE may not monitor for or may not decode downlink control information scheduling CLI measurements in resources that the UE has a scheduled downlink reception according to a periodic scheduling configuration. In some examples, the UE may prioritize a colliding CLI measurement and downlink transmission based on an indicated priority of each, a type a CLI measurement, a type of downlink transmission, and/or a location of the UE within the cell. The UE may either monitor for the downlink transmission or perform the CLI measurement based on the priority scheme.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an indication of a first transmit power configuration and a second transmit power configuration for a physical uplink shared channel (PUSCH) communication. The wireless communication device may transmit, using a first transmit power that is based at least in part on the first transmit power configuration, a first portion of the PUSCH communication in a full-duplex portion of a time-frequency resource. The wireless communication device may transmit, using a second transmit power that is based at least in part on the second transmit power configuration, a second portion of the PUSCH communication in a non-full-duplex portion of the time-frequency resource.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a wireless device (e.g., a user equipment (UE) or a base station) receiving, from a network node, a machine learning model for use by the wireless device to detect remote interference from a base station. The wireless device may be associated with a first cell and the base station may be associated with a second cell different from the first cell. The wireless device may input one or more parameters into the machine learning model and detect whether the remote interference from the base station is present based on an output of the machine learning model.
