Abstract: Triangular inter-user equipment coordination for new radio sidelink communications is provided. An exemplary apparatus may include at least one processor, and at least one memory. The memory stores instructions that, when executed by the processor, may cause the apparatus at least to receive, from a first device, a request of inter-user equipment coordination. The apparatus may also be caused to determine at least one second device to which to forward the request. The apparatus may also be caused to modify the request and forward the modified request to the at least one second device for the second device to provide a response to the request to the first device. The request may be modified by an indication related to the forwarding to the at least one second device.

Abstract: Disclosed is a method comprising initiating, by an apparatus, an activation procedure for activating one or more positioning reference units for a positioning session of the apparatus; wherein the activation procedure is initiated via a small data transmission based on at least one of: a number of detected network nodes being above a first threshold value, or a number of detected positioning reference units being above a second threshold value; or wherein the activation procedure is initiated by transmitting an activation request to the one or more positioning reference units over sidelink based on the number of detected positioning reference units comprising at least the one or more positioning reference units.

Abstract: Disclosed is a method comprising obtaining a first set of measurement information associated with a reference signal transmitted from a set of positioning reference units; selecting a subset of positioning reference units from the set of positioning reference units, wherein the selection is based at least on determining that the reference signal transmitted per positioning reference unit of the subset of positioning reference units is measured by a same set of network nodes that measured a reference signal transmitted from a target user device; and refining a location estimate of the target user device based at least on a subset of measurement information from the first set of measurement information, wherein the subset of measurement information is associated with the subset of positioning reference units.

Abstract: A method may include receiving, by a first user device from a network node or a second user device, 1) a positioning measurement report including at least one positioning measurement measured by a reference device, and 2) reference positioning-related information to be used for testing and/or validating a machine learning model; determining estimated positioning-related information as outputs of the machine learning model based on at least a portion of the positioning measurement report as inputs to the machine learning model; determining a performance indication of the machine learning model based on the reference positioning-related information and the estimated positioning-related information, wherein the performance indication indicates a performance or accuracy of the machine learning model; and performing, by the first user device, an action based on the performance indication.

Abstract: Disclosed is a method comprising determining one or more radio access nodes based on available location information of a target user device and at least one neighboring user device of the target user device; transmitting a sidelink information request to the one or more radio access nodes, wherein the sidelink information request indicates requesting sidelink information of the target user device and the at least one neighboring user device of the target user device; receiving the sidelink information from the one or more radio access nodes; and transmitting, to at least one of the one or more radio access nodes and/or the at least one neighboring user device, at least a part of a locality database and/or a sidelink positioning configuration for positioning the target user device, wherein the locality database and/or the sidelink positioning configuration are based at least on the sidelink information.

Abstract: Various example embodiments are described in which a network node transmits to a user device preconfiguration information for a plurality of on-demand positioning signal (ODPS) preconfigurations. An ODPS preconfiguration may be selected and communicated. The transmitted ODPS preconfiguration may be a request for transmission, or a notice of transmission, of the selected ODPS. An ODPS, which is associated with or based on the selected ODPS preconfiguration, may be transmitted. The ODPS may include any positioning signal (e.g., any signal that may be used for positioning) that may be transmitted upon request or as needed, and, e.g., may include downlink on-demand positioning reference signals (ODPRS), uplink on-demand sounding reference signals (ODSRS), or other positioning or reference signal.

Abstract: The present disclosure relates to a user equipment that includes a communication interface configured to perform communication with one or more nearby UEs using one or more of a plurality of resources in a cellular communication network, and processing circuitry configured to operate the UE in a first mode and in a second mode. The first mode is a scheduled resource allocation mode, and the second mode is an autonomous resource selection mode or an idle mode. The processing circuitry is configured to switch from the first mode to the second mode based on a first condition relating to an out of coverage event of the UE being met and a second condition related to a further parameter being met.
