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: There is provided an apparatus, and corresponding meth-od, configured to receive, from a network element, an indi-cation that a terminal device is to determine a current convergence speed of a positioning algorithm used to deter-mine a position result of the terminal device; determine the position result of the terminal device using the positioning algorithm; determine the current convergence speed of the positioning algorithm used when determining the position result of the terminal device; determine a relative conver-gence speed of the positioning algorithm, based on the cur-rent convergence speed; and indicate to the network ele-ment at least one of: the relative convergence speed, at least one value obtained based on the current convergence speed, an integrity result of the determined position result, or the determined position result of the terminal device.

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.
