Example embodiments of the present disclosure relate to transmission of control information associated with sidelink positioning reference signal. In an example method, a first terminal device in a radio access network comprises at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the first terminal device to: transmit, to a second terminal device in the radio access network, control information associated with a sidelink (SL) positioning reference signal (PRS) during a SL positioning session for positioning of the second terminal device, using a resource for the control information in a Physical Sidelink Feedback Channel (PSFCH) symbol or in at least one symbol dedicated for the control information. In this way, the first terminal device can efficiently transmit control information to the second terminal device with backward compatibility.

Transmission of control information associated with sidelink positioning reference signal

A method for positioning in a sidelink communication. The method includes detecting, by an anchor component, a presence of at least one user equipment; and activating, by the anchor component, a transmission of a positioning reference signal to the user equipment responsive to the detected presence of the at least one user equipment.

Transmission of positioning reference signals for sidelink communications

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.

Positioning reference unit selection

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.

Devices and methods for device to device (D2D) communication

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.

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.
