Abstract: Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage medium for synchronization reference alignment. In a method, a server device obtains first information indicating at least one of: a role of a device of at least one device during positioning of a target device based on at least sidelink positioning reference signals, or quality of a plurality of links between the device of the at least one device and a plurality of positioning anchor devices for the positioning of the target device. Based on at least the first information, the server device determines a common synchronization reference source for synchronization of at least one of the plurality of positioning anchor devices.

Abstract: Systems, methods, apparatuses, and computer program products for reducing user equipment (UE) transmit (Tx) timing error group (TEG) reporting overhead. A method may include receiving, from a first network element, an indication that a sounding reference signal for positioning will be used for uplink and downlink plus uplink positioning. Configuration for the sounding reference signal resource for positioning may be received from a second network element. The sounding reference signal resource for positioning may be associated with a user equipment transmit timing error group. The first network element or the second network element may be informed that a user equipment will report the user equipment transmit timing error group association to the first network element or to the second network element. The user equipment transmit timing error group association may be reported to the first network element or to the second network element.

Abstract: Systems, methods, apparatuses, and computer program products for dynamic gap symbol in sidelink positioning reference signal (SL PRS) resource configuration. A method may include receiving, from a user equipment, a sidelink control information indicating whether a gap symbol exists for a sidelink positioning reference signal transmission. The method may also include determining a time domain allocation of the sidelink positioning reference signal. The method may further include receiving, from the user equipment, a sidelink positioning reference signal with or without the gap symbol. In addition, the method may include performing a positioning computation based on the sidelink positioning reference signal received from the user equipment.

Abstract: Inter-alia, a method e.g. performed by an anchor user device is disclosed comprising:



receiving a first target sidelink positioning reference signal;
transmitting a first anchor sidelink positioning reference signal;
performing a receiver-transmitter time difference measurement based on the first target sidelink positioning reference signal and the first anchor sidelink positioning reference signal;
transmitting an indication of a suggestion to switch from a first sidelink round-trip time positioning method to a second round-trip time positioning method based on the receiver-transmitter time difference measurement.




Further, inter-alia a method performed by a target user device is disclosed as well as respective anchor and target user devices.

Abstract: Systems, methods, apparatuses, and computer program products for connected mode mobility management for group of users in a vehicle and served by the non-terrestrial network deployments are provided. For example, a method can include detecting, by a user equipment, a cell-edge condition while the user equipment is being served through non-terrestrial radio access. The user equipment can also initiate prioritized transmission conditioned on the detected cell-edge condition and can transmit uplink data transmission using the prioritized transmission before leaving coverage provided by the non-terrestrial radio access.
