Abstract: Example embodiments may relate to systems, methods and/or computer programs relating to positioning, for example for terminating or adapting an established positioning session under certain conditions. For example, the method may involve monitoring, for a plurality of time instances during transmission over a wireless channel of a positioning signal from a first terminal to a second terminal as part of a positioning session, one or more features of the wireless channel. The method may also involve identifying based on a value of one, or a combination, of the monitored one or more features between a first time instance and a second time instance, a change indicative of transition of at least one of the first and second terminals from a first environment to a second environment. The method may also involve causing termination or adaptation of the active positioning session responsive to the identification.

Abstract: According to an example embodiment, a client device is configured to receive at least one sidelink signal in a time slot over a plurality of subchannels; identify, using at least one detection model, a plurality of potentially active demodulation reference signal configurations out of a plurality of possible demodulation reference signal configurations in the time slot across the plurality of subchannels based on the at least one sidelink signal, wherein each demodulation reference signal configuration defines demodulation reference signal transmissions in the time slot; identify payload transmissions in the time slot based on the identified plurality of potentially active demodulation reference signal configurations in the time slot; and create at least one decoding path for the payload transmissions in the time slot based on the identified payload transmissions in the time slot and the identified plurality of potentially active demodulation reference signal configurations. Devices, methods and computer programs are disclosed.

Abstract: A solution for sidelink-assisted positioning of a terminal device. In an embodiment, a procedure in the terminal device includes transmitting, over a sidelink, a message including at least one information element requesting at least one anchor terminal device to report its location to the terminal device; receiving, over the sidelink from the at least one anchor terminal device, a location report including at least one information element indicating a location of the reporting anchor terminal device and an accuracy metric indicating accuracy of the location; determining a location estimate of the terminal device based on the accuracy metric and the location of the at least one anchor terminal device.

Abstract: Embodiments of the present disclosure relate to apparatuses, methods, and computer readable storage media for multi-consecutive slots transmission (Multi-consecutive slots transmission). An apparatus obtains at least one group of single-slot candidate resources available for a sidelink transmission. The apparatus determines, based on a first number of slots for multi-consecutive slots transmission, a first set of multi-consecutive slots transmission candidate resources from the at least one group of single-slot candidate resources, a multi-consecutive slots transmission candidate resource comprising the first number of consecutive slots. If the first set of multi-consecutive slots transmission candidate resources meets at least one multi-consecutive slots transmission candidate resource condition, the apparatus selects a target resource for transmission of the multi-consecutive slots transmission from the first set of multi-consecutive slots transmission candidate resources. Otherwise, the apparatus determines the target resource for transmission of the multi-consecutive slots transmission based on a multi-consecutive slots transmission criterion.
