    Abstract: Embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage media for isolation enforcement for delivery of sidelink positioning protocol (SLPP) messages. In the methods, a first apparatus receives, from a second apparatus, a request comprising a first indication that is to be indicated to a third apparatus. The first apparatus and the second apparatus are involved in a sidelink positioning process. Then, the first apparatus transmits the first indication to the third apparatus. Furthermore, the first apparatus transmits, to the second apparatus, information at least indicating reachability between the first apparatus and the third apparatus based on monitoring of feedback information associated with the first indication from the third apparatus. Thereby, the proposed methods can advantageously support the delivery of SLPP messages to out-of-reach devices.

    Abstract: This document discloses a solution for performing rerouting of a relayed connection. In an aspect, a method for an anchor terminal device supporting relaying between an access node and an end terminal device comprises: receiving a message requesting rerouting of said relaying, the message comprising at least one information element indicating at least one candidate terminal device; determining a communication delay between the anchor terminal device and the end terminal device via at least one of said at least one candidate terminal device and comparing the determined communication delay with a maximum delay threshold; if at least one determined communication delay is smaller than the maximum delay threshold, rerouting the relaying between the anchor terminal device and the end terminal device via one of the at least one candidate terminal device that provides the communication delay smaller than the maximum delay threshold, wherein the rerouting is carried out autonomously without receiving from the access node a reconfiguration message instructing the rerouting configuration; and if no communication delay is smaller than the maximum delay threshold, causing transmission of a message to the access node, the message indicating a need for reconfiguration of the relaying.

    Abstract: A method includes obtaining a first power measurement associated with resource blocks (RBs) being utilized by a terminal device (TD). The method includes determining whether the first power measurement satisfies a first threshold. The method includes, upon determining that the first power measurement satisfies the first threshold, transmitting, to a target TD, a positioning reference signal (PRS). The method includes, determining whether the first power measurement does not satisfy the first threshold and, in response, determining a set of comb parameters. The method includes obtaining, based on the set of comb parameters, a second power measurement associated with resource elements (REs) related to the RBs. The method includes determining whether the second power measurement satisfies a second threshold. The method includes, upon determining that the second power measurement satisfies the second threshold, transmitting, based on the set of comb parameters, the PRS to the target TD.

    Abstract: Embodiments of the present disclosure relate to sidelink positioning session establishment. In an aspect, a terminal device obtains session information associated with a first sidelink positioning session, and determines, based on the session information, difference information between the first sidelink positioning session and a second sidelink positioning session in which the terminal device is a target device. The terminal device transmits a positioning request for determining at least one anchor device to perform the second sidelink positioning session, wherein the positioning request comprises the difference information. The terminal device performs the second sidelink positioning session with the at least one anchor device. The embodiments of the present disclosure can immediately activate the target device in an efficient manner with reduced signaling overhead and latency.
