Abstract: Aspects described herein relate to determining and/or scheduling resources for devices in view of cross-channel interference measured between the devices. In an aspect, a first user equipment (UE) can determine a signal measurement of a signal transmitted by a second UE in a first channel, determine, based at least in part on the signal measurement, a cross-channel interference parameter of interference experienced by the first UE, and transmit, to a serving base station that serves the first UE, an indication of the cross-channel interference parameter. In another aspect, a base station can determine a cross-channel interference parameter of interference experienced by a first UE in at least a first channel, based on a signal transmitted by a second UE in a second channel, and can schedule communications for the first UE based at least in part on the cross-channel interference parameter.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a first device may calculate hybrid beamforming parameters for a second device. The first device may calculate the hybrid beamforming parameters based on an estimation of channel information associated with at least a portion of a communication link at the second device via a machine learning model. Inputs to the machine learning model may include measured model parameters based on measurements performed by one or more other devices. The first device may transmit a message to the second device to indicate the hybrid beamforming parameters, which may include an input for a beam refinement process. The second device may perform the beam refinement process based on the hybrid beamforming parameters to identify one or more beams. The first and second devices may communicate using the one or more beams based on the beam refinement process.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request for symbol aggregation over a common symbol across a set of multiple downlink transmit beams of a network entity. The UE may receive, based on the request, a downlink grant scheduling one or more slots associated with symbol aggregation over the common symbol across the set of multiple downlink transmit beams of the network entity. The UE may receive, during the one or more slots, a set of multiple repetitions of a common data symbol, each repetition of the set of multiple repetitions of the common data symbol transmitted via a respective downlink transmit beam of the set of multiple downlink transmit beams.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for beam formed partial sensing by a user equipment (UE). An example method generally includes performing partial sensing by monitoring for sidelink transmissions from one or more other UEs using one or more different beams during one or more different portions of a sensing window; and selecting resources, within a resource selection window, for future sidelink communications based on results of the partial sensing.

Abstract: Methods, systems, and devices for wireless communications are described that provide for measurement and recovery of beamformed transmission beams in which an uplink beam and a downlink beam may be decoupled beams that use different beamforming parameters. In the event that a user equipment (UE) detects a failure of the downlink beam, an indication may be provided to a base station, and the downlink beam may be switched to correspond to the uplink beam. In the event that the UE detects a failure of the uplink beam the UE may identify a candidate beam and transmit a beam recovery message to the base station. The downlink beam may have an associated first set of reference signals, and the uplink beam may have an associated second set of reference signals, and beam failure may be determined based on the different sets of reference signals.

Abstract: A user equipment may be configured to perform UE indication to temporarily suspend report occasions. In some aspects, the user equipment may receive report configuration information from a base station, the report configuration information identifying a report parameter to provide in a channel state information (CSI) report, and determine a predicted value of the report parameter based on a plurality of historic measurements. Further, the user equipment may determine to suspend transmission of the report parameter based on the predicted value, and transmit a report suspension message to the base station, the report suspension message indicating that the UE has implemented a temporary suspension of reporting of the report parameter in the CSI report.

Abstract: In an embodiment, a UE identifies a pool of resources where transmission of sidelink synchronization signals is permitted, the pool of resources including at least UE-specific resources, and transmits a sidelink synchronization signal to one or more peer sidelink UEs based on a subset of the pool of resources. In another embodiment, a UE transmits a synchronization request message to at least one peer sidelink UE, and receives at least one sidelink synchronization signal from the at least one peer sidelink UE in response to the transmission of the synchronization request message.
