Abstract: A system and method for positioning for line-of-sight and non-line-of sight environments. In some embodiments, the method includes: receiving, by a User Equipment (UE), from a first Transmission and Reception Point (TRP) of a network, a Positioning Reference Signal (PRS); and sending, by the UE, a response to the network. The sending may include sending an indicator, the indicator indicating whether the UE has performed a measurement based on the Positioning Reference Signal, received via a line-of-sight path; or the sending may include identifying a first detected path and sending a plurality of measurements to the network, the plurality of measurements including, for each of a first plurality of paths, the arrival time difference relative to the arrival time of the first detected path, the first plurality of paths not including the first detected path, and the first plurality of paths including two paths.

Abstract: A system and a method are disclosed for verifying reported measurements for UE location. A method of network verified UE location includes configuring, by a network device, a base station with a first resource for transmitting a PRS to a UE at a time t1; configuring, by the network device, the UE with a second resource for transmitting an SRS to the base station at a time t3; receiving, by the network device, from the base station, a value for t1 and a value for t4, wherein the base station is configured to receive the SRS from the UE at a time t4; receiving, by the network device, from the UE, a value for t2 and a value for t3, wherein the UE is configured to receive the PRS from the base station at a time t2; and verifying, by the network device, the values for t2 and t3 received from the UE, based the received values for t1, t2, t3, and t4.

Abstract: A method of reporting a user equipment (UE) time difference in a non-terrestrial network (NTN) is provided, the method includes receiving, from a base station, a positioning reference signal (PRS) in downlink (DL); determining a timestamp or subframe indices of the PRS in DL and a timestamp or subframe indices of the UE uplink (UL) PRS's closest subframe; determining, based on the timestamps or subframe indices, the UE time difference from the reception of the PRS to a transmission of a sounding reference signal (SRS); and reporting, to a location management function (LMF), the SRS based on the UE time difference.

Abstract: A method and a device are provided in which a request for positioning assistance is received from a UE in a dedicated field of sidelink (SL) control information (SCI). A request for assistance in selecting resources for SL-positioning reference signal (PRS) transmission is transmitted to the UE. A set of one or more preferred or non-preferred resources for SL-PRS transmission is received from the UE. Resources for the SL-PRS transmission are selected based on at least the set of one or more preferred or non-preferred resources.

Abstract: A system and a method are provided in which a user equipment (UE) obtains a positioning reference signal (PRS) configuration message from an anchor UE based on a basic safety message (BSM) of the anchor UE. The UE receives a sidelink PRS from the anchor UE based on the PRS configuration message, and perform a positioning measurement based on the received PRS.

Abstract: A system and a method are provided in which a user equipment (UE) obtains a set of coefficients and a set of subcarriers from a location management function (LMF), and measures carrier phases on subcarriers, from the set of subcarriers, of a received reference signal transmitted with multi-carrier modulation. The UE determines a virtual carrier phase generated from the measured carrier phases and corresponding coefficients, from the set of coefficients. The UE reports the virtual carrier phase to the LMF.
