Abstract: Disclosed are techniques for signaling of reception-to-transmission measurements from gNBs and user equipments (UEs) for round trip time (RTT) based positioning in wireless networks such as new radio (NR). In multi-RTT positioning, the flow of messages that are exchanged differ depending on the entity acting as the location server determining the position of the UE.

Abstract: Disclosed are techniques for determining round-trip times (RTTs) between a user equipment (UE) and multiple base stations. In an aspect, the UE transmits an RTT measurement signal whose arrival time is measured by each of the base stations, and each of the base stations returns an RTT response signal whose arrival times are measured by the UE. In another aspect, the base stations each transmit an RTT measurement signal and the UE returns an RTT response signal. The receiver of the RTT measurement signal may include the measured arrival time in a payload of the RTT Response signal. Alternatively, the measured arrival time(s) of the RTT Measurement signal(s) and the transmission time(s) of the RTT Response signal(s) are sent in a separate message. The RTT signals can be wideband signals using low reuse resources.

Abstract: Techniques are discussed herein for efficiently supporting broadcast of location assistance data (AD) in a wireless network to assist in locating a user equipment (UE). A location server (LS) may send some location AD, which may be optionally ciphered, to base stations for broadcast in cells supported by the base stations. Capability information provided by a UE to the LS indicating a level of support by the UE for receiving broadcast AD and supporting ciphering may enable the LS to determine whether, and what type of, additional AD needs to be sent to the UE by point to point means. An LS may use capability information received from a large number of UEs to assist in determining the types of location assistance data to be broadcast and usage of ciphering.

Abstract: A RAN location server function (e.g. for 5G New Radio), referred to as Location Management Component (LMC), may be included in a gNB and connected to a gNB Central Unit (gNB-CU). The gNB-CU may receive a location request for a UE (e.g. from an AMF) and may initiate a location session for the UE, including selecting an LMC for the location session. The gNB-CU may handover the UE to a new serving gNB during the location session. The LMC for the location session may then remain unchanged after the handover or may be changed to a new LMC to suit the new serving gNB. The location session may then continue using the original LMC if not changed or the new LMC if changed.

Abstract: Positioning assistance data (PAD) may be partitioned into positioning System Information Blocks (posSIBs) and periodically broadcast by a base station. A posSIB or scheduling information for a posSIB may include a validity time and a validity tag that indicates whether the PAD for a posSIB has changed. A user equipment (UE) may receive a posSIB comprising PAD and the validity time and the validity tag for the posSIB. The UE may then wait until the validity time expires and/or the validity tag in the scheduling information indicates a change of PAD before receiving a new instance of the posSIB. The validity time and validity tag may both be included in the posSIB, in which case the UE may receive the posSIB and then look at the validity tag to determine whether to decode and process the PAD.

Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a positioning device may identify a motion state configuration associated with a mobile device, the motion state configuration including information indicating possible positions of the mobile device during a movement of the mobile device; and determine a position of the mobile device based at least in part on the motion state configuration. In some aspects, a device may identify a motion state configuration associated with a mobile device, the motion state configuration including information indicating possible positions of the mobile device during a movement of the mobile device; and provide, to a positioning device, the motion state configuration in association with determining a position of the mobile device. Numerous other aspects are provided.

Abstract: Techniques are disclosed in which generic position methods in a wireless network allow positioning of a target user equipment (UE) that is served by any one (or more) of a number of different Radio Access Technologies (RATs) and that allow measurements by the UE of access nodes belonging to different RATs and/or measurements of the UE by access nodes for different RATs. With a generic position method, a common set of procedures, messages, and parameters may be defined that are applicable to multiple RATs and that do not require a location server to know in advance the serving RAT for a target UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may report measurements of a signal transmitted by a base station via a waveform. Based on the waveform, the base station may determine a position of the UE. The UE may measure the signal in a frequency band, where additional signaling in an adjacent frequency band causes interference on the signal. The UE may determine characteristics for measuring the signal based on the interference and may generate samples of the signal based on the measurement characteristics. Additionally, the UE may identify one or more antennas for measuring the signal and generate the samples based on the identified antennas. The UE may transmit the waveform report to the base station based on the samples. In some cases, the waveform may be based on a fractional symbol reporting scheme or a time mask with an offset and sampling rate.
