Abstract: Certain aspects of the present disclosure provide techniques for facilitating the use of random access channel occasions for full-duplex communication. An example method performed by a user equipment (UE) in a first group of UEs may include receiving, from a base station (BS) of a wireless network, a first indication indicating, from a first plurality of random access channel occasions (ROs) not available for use by a second group of UEs within the wireless network, a set of ROs that are available for use by the first group of UEs within the wireless network, receiving a first signal of a plurality of signals transmitted by the BS, and transmitting, in response to receiving the first signal, a random access preamble in a first RO of the set of ROs based on a mapping between the first signal and the first RO.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for signaling whether to generate cross-link interference (CLI) measurement reports based on a single CLI measurement occasion or based on multiple CLI measurement occasions. A network entity may indicate whether to generate a CLI measurement report based on a single most recent CLI measurement occasion or based on CLI measured over a number of CLI measurement occasions. The measuring user equipment (UE) may generate a CLI report based on a single most recent CLI measurement occasion or based on a statistical CLI measurement based on respective CLI measurements for each respective CLI measurement occasion of the number of CLI measurement occasions depending on the indication. The network entity may also indicate to the aggressor UE to repeat transmission of sounding reference signals using the same transmit beam during the CLI measurement occasions.

Abstract: Certain aspects of the present disclosure provide techniques for communicating uplink and downlink transmissions when a semi-statically configured scheduling occasion is overwritten by a slot format indicator. A method performed by a user equipment (UE) includes receiving a control message from a base station (BS) activating a semi-static scheduling configuration, wherein the semi-static scheduling configuration indicates a plurality of configured grant (CG) symbols in which the UE is scheduled to transmit at least one uplink transmission to the BS. The method may further include receiving, from the BS, a slot format indicator (SFI) that overwrites a subset of CG symbols of the plurality of CG symbols to be downlink symbols, and taking one or more actions to communicate at least one downlink transmission in the downlink symbols.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a victim network entity to share a downlink preemption pattern with user equipments (UEs) and neighboring network entities. For example, the victim network entity may transmit, to a UE and/or a neighbor network entity, control signaling indicating a recurring downlink preemption pattern defining one or more resources during which the UE may preempt reception of downlink signaling and the victim and neighbor network entities may preempt transmission of downlink signaling. The UE and the network entities may refrain from monitoring for downlink transmissions and transmitting downlink transmissions, respectively, in accordance with the indicated downlink preemption pattern. In some examples, the UE and the network entities may be configured with one or more conditions for discarding the indicated downlink preemption pattern and monitoring the one or more resources for or transmitting downlink transmissions.

Abstract: Methods, systems, and devices for sidelink assisted cross-link interference (CLI) determination are described. In some examples, a first wireless device may perform a first measurement of a sidelink message received from a second wireless device. As such, the first wireless device may transmit, to a base station, a report indicating that the second wireless device is estimated to be within a defined proximity of the first wireless device based at least in part on the first measurement satisfying a threshold. In some examples, the first wireless device may receive a control message, from the base station, scheduling transmission of a message between the base station and the first wireless device in a frequency resource in response to the report that the second wireless device is estimated to be within the defined proximity of the first wireless device.

Abstract: Wireless communications systems and methods related to resolving conflicts between full-duplex signals are provided. A base station may schedule resources for a UE or plurality of UEs. The scheduled resources may include simultaneous uplink and downlink resources. The scheduled resources may utilize beams which if used would cause excessive interference. As such, a conflict resolution action may be performed by the BS and UE to mitigate any problems arising from using both incompatible beams simultaneously. Conflict resolution actions may include dropping one of the signals. Conflict resolution actions may include and changing one or both beam configurations for the signals. Conflict resolution actions may be based on predetermined rules or may be based on an indication from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the present disclosure provide techniques to achieve inter-base station beam management to avoid interference during full-duplex (FD) operations, half-duplex (HD) operations, flexible time-domain duplexing (TDD), or a combination thereof, by performing interference management specific to beam configurations. For example, a first base station (e.g., an aggressor base station operating in FD) may perform one or more actions to proactively determine if inter-base station interference may occur. In some cases, the aggressor base station may request measurements from one or more victim base stations. In other examples, the victim base station may request measurements from the aggressor base station. Additionally or alternatively, the victim base station may provide reactive feedback to the aggressor base station upon detecting interference.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may indicate to a UE a first set of uplink power control parameters associated with half-duplex communications and a second set of uplink power control parameters associated with full-duplex communications. Alternatively, the base station may indicate the first set of uplink power control parameters and a set of power offsets associated with full-duplex communications. The base station may indicate a first set of resources associated with the first set of uplink power control parameters and a second set of resources associated with the second set of uplink power control parameters or the set of power offsets. In response, the UE may transmit one or more uplink messages over one or more resources of the second set of resources in accordance with the second set of uplink power control parameters or the set of power offsets.
