Abstract: Certain aspects of the present disclosure provide techniques for interference mitigation negotiation between network entities. An example method performed by a first network entity includes receiving, via different receive beams of the first network entity, a plurality of reference signals (RSs) from a second network entity associated with different transmit beams of the second network entity, transmitting, based on the plurality of RSs, downlink (DL) transmission recommendation information to the second network entity for a transmission window, and taking one or more actions related to receiving one or more uplink (UL) transmissions via one or more receive beams during the transmission window based, at least in part, on the DL transmission recommendation information.

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 message that is associated with a full duplex transmission mode. The configuration message includes at least one indicator of a resource for channel measurement, where the at least one indicator of the resource for channel measurement is associated with a plurality of resources for interference measurements that include at least one resource for self-interference measurement. Additionally, or alternatively, the configuration message includes at least one indicator of a format for a sub-band report, where the format indicates that the sub-band report is to include at least one of reference signal received power, signal-to-interference-and-noise ratio, or a combination thereof. The UE may transmit, to the base station, at least one report based at least in part on the configuration message. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity, such as a base station, may receive, from a first network entity, a broadcast indicating a downlink control channel transmission pattern associated with the first network entity. The network entity may monitor a plurality of receive beams for a plurality of downlink control channel transmissions from the first network entity according to the downlink control channel transmission pattern and may select a communication beam according to one or more cross-link interference (CLI) measurements associated with one or more of the plurality of receive beams in accordance with the monitoring. The network entity may communicate with a user equipment using the selected communication beam and a first set of resources that at least partially overlap in time and frequency with a scheduled communication at the first network entity. The network entity may experience or may cause the measured CLI.

Abstract: A UE receives a configuration for one or more downlink reference signal or downlink channel from a base station and receives an indication of one or more time and frequency resources for full-duplex communication at the base station. The UE skips reception of the one or more downlink reference signal or downlink channel based at least in part on the indication of the one or more time and frequency resources for the full-duplex communication at the base station. A UE receives, from a base station, an allocation of uplink resources for an uplink transmission and receives an indication of one or more time and frequency resources for full-duplex communication at the base station. The UE transmits the uplink transmission to avoid the one or more time and frequency resources for the full-duplex communication at the base station.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer-readable medium for transmitting at least one capability signal to a network entity, wherein the at least one capability signal indicates whether at least one filter in at least one receive chain of the UE is adaptively switchable between a first configuration and a second configuration, wherein the first configuration supports half-duplex communication with the network entity, wherein the second configuration supports sub-band full duplex communication with the network entity; and exchanging a signal between the UE and the network entity according to the at least one capability signal.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques for restricting beams that may lead to inter-base station interference. For example, an implicit restriction of beams may be used by a first and second base station (e.g., a victim and aggressor base station, respectively). In such cases, the first base station may indicate a period, a subband, or both, associated with one or more scheduled uplink beams that the first base station may use for receiving uplink transmissions. The second base station may select beams that avoid interference with the uplink beam(s) of the first base station. Additionally or alternatively, an explicit restriction of beams may be signaled, where the first base station may explicitly indicate a set of downlink beams associated with the second base station that are allowed (e.g., beams that avoid interference with uplink transmissions at the first base station).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may identify interference associated with a first direction on a resource. The first network node may transmit, to a second network node in a time window associated with the resource, an indication that the resource is restricted with regard to communications, by the second network node, in a second direction on the resource, wherein the second direction is opposite the first direction. The first network node may communicate based at least in part on the indication. Numerous other aspects are described.
