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.

Abstract: Examples of the disclosure relate to sidelink positioning. In examples of the disclosure a UE is configured to determine Discontinuous Reception (DRX) assistance information for sidelink positioning. The DRX assistance information comprises information indicative of a DRX configuration information for one or more target UEs. The UE can then enable transmission of the DRX assistance information to one or more candidate anchor UEs.

Abstract: Embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage media for dynamic configuration of measurement parameters for sidelink positioning. In the method, a first apparatus receives, from a second apparatus, a plurality of measurement configurations for sidelink positioning. Moreover, in accordance with a determination that a first trigger condition defined the plurality of measurement configurations is met, the first apparatus determines a first measurement configuration corresponding to the first trigger condition from the plurality of measurement configurations. Thereby, the proposed solutions can advantageously improve the positioning accuracy.
