Abstract: Apparatus and methods for apparatus positioning are provided. Solution includes receiving (300) by an apparatus from a network element a signal having multipath propagated signal components and obtaining time domain samples of the multipath propagated signal components, mapping (302) the time domain samples to one or more frequency offset-delay pairs to obtain frequency offsets and delays of the received multipath propagated signal components, calculating (304) angle of arrival of one or more multipath propagated signal components, determining (306) the multipath propagated signal component corresponding to the direct propagation path between the apparatus and the network element, and controlling (308) the utilisation of the angle of arrival and delay of the multipath propagated signal component corresponding to the direct propagation path in the determination of the location of the apparatus.

Abstract: Systems, methods, apparatuses, and computer program products for positioning measurements are provided. One method may include receiving, from a user equipment, a number of supported receive and transmit panels that can be simultaneously activated and/or a panel switch time. The method may then include computing or otherwise determining a UE-based latency lag using the number of supported receiver and transmitter panels that can be simultaneously activated and the panel switch time.

Abstract: Positioning in a first terminal device that performs receiving from a coordination entity an anchor feared event request for sidelink positioning of a target device; and transmitting an anchor feared event response that indicates an integrity of the first terminal device candidate as a positioning anchor device for the target device. The anchor feared event response includes at least one of following feared event indicators: a link quality characteristic of a channel between the first terminal device and the target device; or power headroom of the first terminal device. A corresponding method in the coordinating entity, and computer program, apparatus, and non-transitory computer readable medium are also disclosed.

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.
