Abstract: Methods, apparatuses, and computer program products provide means for functionality selection assistance to determine selection of a preferred functionality for an Artificial Intelligence/Machine Learning model feature. An example method includes: receiving a request for supported functionalities from a network node; identifying the supported functionalities; determining functionality selection assistance information; and providing an indication of the supported functionalities and the functionality selection assistance information to the network node. A method can optionally include receiving an indication of a selected functionality of the supported functionalities based, at least in part, on the functionality selection assistance information; and employing the selected functionality to support a feature.

Abstract: The present disclosure relates to reference signal transmission alignment. In particular, a target device determines whether a reference signal transmission alignment is needed among a set of anchor devices. If the reference signal transmission alignment is needed, an anchor device receives a request for the reference signal transmission alignment. The anchor device determines a transmission time window based on the request and transmits a reference signal as per the transmission time window. In this way, it can mitigate an impact of synchronization timing reference change at the target device in measurement. Consequently, the solution allows for high accuracy measurements and hence enables high accuracy sidelink positioning.

Abstract: Systems, methods, apparatuses, and computer program products for dynamic gap symbol in sidelink positioning reference signal (SL PRS) resource configuration. A method may include receiving, from a user equipment, a sidelink control information indicating whether a gap symbol exists for a sidelink positioning reference signal transmission. The method may also include determining a time domain allocation of the sidelink positioning reference signal. The method may further include receiving, from the user equipment, a sidelink positioning reference signal with or without the gap symbol. In addition, the method may include performing a positioning computation based on the sidelink positioning reference signal received from the user equipment.
