Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate a support for an end-to-end multi-block machine learning application, a first UE capability for a backbone block of the multi-block machine learning application that makes up one or more front-end layers (e.g., one or more backbone layers), a second UE capability for a task-specific block of the multi-block machine learning application that makes up the end layer (s) of the end-to-end model (e.g., one or more task-specific layers), or a combination thereof. In some examples, the UE may transmit separate indications for the first UE capability and for the second UE capability. Additionally or alternatively, the UE may transmit a general machine learning capability indication, where a base station then determines the first UE capability for the base stage and the second UE capability for the task-specific stage from the general machine learning capability.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit feedback to a base station indicating phase values for sub-bands in a bandwidth part (BWP). The base station may use the phase feedback to perform precoding on a set of beams. To support a reduced payload overhead for the feedback, the UE may implement differential phase feedback. For example, the UE may divide the BWP into a number of sub-band groups and may generate, for each sub-band group of each beam, a first set of bits indicating an absolute phase value for a first sub-band of the sub-band group. The UE may additionally generate a second set of bits indicating differential phase values for the other sub-bands of each sub-band group. The UE may report the first and second sets of bits for the beams to the base station for precoding.

A method that may be performed by a UE generally includes receiving, from a base station (BS), a configuration for the UE to perform RF sensing. The method generally includes transmitting an RF sensing signal based on the configuration. The method generally includes performing one or more measurements of one or more reflections of the RF sensing signal. Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a BS. The method generally includes receiving a RF sensing capabilities message from a UE. The method generally includes transmitting, to the UE, a configuration for the UE to perform RF sensing based on the RF sensing capabilities message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may receive a first downlink determining, based at least in part on an uplink transmission schedule for a user equipment (UE), one or more communications that are to be transmitted as a cross link interference reference signal (CLI-RS) during a time window. The BS may transmit, to the UE, an instruction to transmit the one or more communications as the CLI-RS during the time window. Numerous other aspects are provided.

Abstract: In some aspects, a base station may transmit, to a user equipment (UE), an instruction that triggers the UE to transmit an uplink random access channel (RACH) message, the instruction identifying a RACH preamble index corresponding to a RACH preamble to be used for the uplink RACH message; transmit, to a plurality of neighbor base stations, information that identifies the RACH preamble index; receive the uplink RACH message from the UE; receive, from the plurality of neighbor base stations, feedback that indicates respective timings with which the uplink RACH message was received by the plurality of neighbor base stations; and estimate a position of the UE based at least in part on a timing with which the uplink RACH message was received by the base station and at least two of the respective timings with which the uplink RACH message was received by the plurality of neighbor base stations.

Abstract: Aspects are provided allowing a first base station to distinguish between cross-link interference and remote interference caused to a second base station and to apply different mitigation mechanisms based on the type of interference. A UE receives from a second base station a reference signal based on a reference signal identifier that indicates a location of the second base station that is experiencing interference from the first base station. The UE sends to the first base station an indication of the reference signal received from the second base station. The first base station receives from the UE the indication of the reference signal from the second base station based on the reference signal identifier. The first base station applies a mitigation mechanism based on whether the reference signal identifier indicates that the second base station is a remote base station or a neighbor base station.
