Abstract: A method for wireless communication by a user equipment (UE), includes receiving, from a base station, a reference signal (RS) on a set of resource elements (REs), the RS having been multiplexed onto the set of REs based on a non-orthogonal cover code, and a number of REs in the set of REs being less than a number of ports associated with the RS. The method further includes estimating, at the UE via a channel estimation neural network, a channel based on receiving the RS. The method still further includes transmitting, to the base station, a feedback report associated with the estimated channel based on receiving the RS.

Abstract: A base station may set one or more bits of DCI that at least one of indicate or trigger a configuration of an ML model at a UE. The configuration may be based on an association between at least one first ML block for a first procedure and at least one second ML block for a second procedure. The at least one second ML block may be dedicated to a task included in a plurality of tasks associated with the at least one first ML block. The base station may transmit the DCI including the one or more bits to the UE, which may cause the UE to configure the ML model including the association between the at least one first ML block for the first procedure and the at least one second ML block for the second procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive an indication on whether to switch from a first machine learning (ML) group to a second ML group or to continue with the first ML group. The UE may switch to the second ML group if the indication is to switch or continuing with the first ML group if the indication is to continue. The UE may perform a first action associated with wireless communication based at least in part on a first model developed with the first ML group if the indication is to continue. The UE may perform a second action associated with wireless communication based at least in part on a second model developed with the second ML group if the indication is to switch. Numerous other aspects are described.

Abstract: Aspects described herein relate to receiving a configuration for cross-link interference (CLI) measurement reporting, wherein the configuration includes, for each component carrier of one or more component carriers, one or more parameters for measuring signals on the component carrier, and a resource setting indicating resources of the component carrier over which to measure signals. One or more measurements of signals received on the resources indicated by the resource setting for the component carrier can be measured based at least in part on the one or more parameters, and reported to a base station.

Abstract: Disclosed are techniques for communication. In an aspect, a wireless node (e.g., UE or BS) measures a first TOA of a first SRS-P from a UE, a second TOA of a reflection of a second SRS-P from the UE off of a first RIS, and a third TOA of a reflection of a third SRS-P from the UE off of a second RIS. The UE transmits, to a position estimation entity, measurement information based on the first, second and third TOAs. The position estimation entity determines a positioning estimate of the UE based at least in part on the measurement information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a span pattern for a super slot that corresponds to a transmission time interval over multiple slots. The UE may monitor, within a span that is specified by the span pattern and that extends across a slot boundary in the super slot, physical downlink control channel candidates for downlink control information. Numerous other aspects are described.

Abstract: In methods and devices configured to perform the methods for managing downlink traffic reception and cross-link interference (CLI), a wireless device may receive from a base station physical downlink control channel (PDCCH) traffic using a first receive (Rx) resource tuning of an Rx resource, determine whether a time period between an end of the PDCCH traffic and a beginning of a CLI measurement opportunity exceeds a threshold duration for tuning the Rx resource to a second Rx resource tuning, and may receive downlink traffic using the first Rx resource tuning in response to determining that the time period between the end of the PDCCH traffic and the beginning of the CLI measurement opportunity is less than or equal to the threshold duration.
