Abstract

Disclosed are systems, methods, and non-transitory media for detecting a positioning attack based on wireless position signaling. For example, a location server can determine a positioning reference signal having at least a first signal portion and at least a second signal portion. An indication of a positioning attack associated with the positioning reference signal can be obtained. The location server can provide, to a base station, a message of transmission preemption of the second signal portion of the positioning reference signal based on the indication of the positioning attack.

Claims (20)

1 . A method of detecting a positioning attack, comprising: determining, by a location server, a positioning reference signal having at least a first signal portion and at least a second signal portion; obtaining an indication of a positioning attack associated with the positioning reference signal; and providing, to a base station, a message of transmission preemption of the second signal portion of the positioning reference signal based on the indication of the positioning attack, wherein the message of transmission preemption provides an indication to the base station to inhibit transmission of the second signal portion of the positioning reference signal periodically or on a pseudo-random basis.
2 . The method of claim 1 , wherein obtaining the indication of the positioning attack comprises: determining a metric associated with the positioning attack.
3 . The method of claim 2 , wherein the metric associated with the positioning attack is based on a plurality of position measurements provided by a plurality of UE devices.
4 . The method of claim 2 , wherein providing the message of transmission preemption of the second signal portion is in response to determining that the metric associated with the positioning attack is greater than a threshold value.
5 . The method of claim 1 , wherein the first signal portion corresponds to a first portion of a slot and the second signal portion corresponds to a second portion of the slot.
6 . The method of claim 1 , wherein the first signal portion corresponds to a first portion of a symbol and the second signal portion corresponds to a second portion of the symbol.
7 . The method of claim 6 , wherein the first portion of the symbol corresponds to a cyclic prefix.
8 . The method of claim 1 , wherein the first signal portion corresponds to a first sub-band within a bandwidth of the positioning reference signal and the second signal portion corresponds to a second sub-band within the bandwidth of the positioning reference signal.
9 . The method of claim 1 , wherein the first signal portion corresponds to a first beam from a plurality of beams associated with a transmission-reception point (TRP) and the second signal portion corresponds to a second beam from the plurality of beams associated with the TRP.
10 . The method of claim 1 , further comprising: receiving at least one signal measurement associated with an unauthorized signal transmitted using one or more resources corresponding to the second signal portion.
11 . The method of claim 10 , further comprising: identifying a transmission-reception point (TRP) associated with the positioning attack based on the at least one signal measurement.
12 . The method of claim 10 , further comprising: identifying one or more UE devices that are outside a range of the unauthorized signal; and configuring the one or more UE devices to ignore the positioning reference signal.
13 . The method of claim 1 , wherein a plurality of user equipment (UE) devices are configured to process the first signal portion and the second signal portion.
14 . An apparatus for detecting a positioning attack, the apparatus comprising: at least one transceiver; at least one memory; and at least one processor coupled to the at least one transceiver and the at least one memory and configured to: determine a positioning reference signal having at least a first signal portion and at least a second signal portion; obtain an indication of a positioning attack associated with the positioning reference signal; and provide, to a base station, a message of transmission preemption of the second signal portion of the positioning reference signal based on the indication of the positioning attack, wherein the message of transmission preemption provides an indication to the base station to inhibit transmission of the second signal portion of the positioning reference signal periodically or on a pseudo-random basis.
15 . The apparatus of claim 14 , wherein to obtain the indication of the positioning attack the at least one processor is further configured to: determine a metric associated with the positioning attack.

Description

FIELD OF THE DISCLOSURE Aspects of the disclosure relate generally to positioning signaling. In some implementations, examples are described for providing partial position signaling to prevent and/or detect positioning attacks. BACKGROUND OF THE DISCLOSURE Wireless communication systems have developed through various generations, including a first-generation analog wireless phone service (1G), a second-generation (2G) digital wireless phone service (including interim 2.5G networks), a third-generation (3G) high speed data, Internet-capable wireless service, and a fourth-generation (4G) service (e.g., Long-Term Evolution (LTE), WiMax). There are presently many different types of wireless communication systems in use, including cellular and personal communications service (PCS) systems. Examples of known cellular systems include the cellular Analog Advanced Mobile Phone System (AMPS), and digital cellular systems based on code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), the Global System for Mobile communication (GSM), etc. A fifth generation (5G) mobile standard calls for higher data transfer speeds, greater numbers of connections, and better coverage, among other improvements. The 5G standard (also referred to as “New Radio” or “NR”), according to the Next Generation Mobile Networks Alliance, is designed to provide data rates of several tens of megabits per second to each of tens of thousands of users with, for example, a gigabit connection speeds to tens of users in a common location, such as on an office floor. Several hundreds of thousands of simultaneous connections should be supported in order to support large sensor deployments. Consequently, the spectral efficiency of 5G mobile communications should be significantly enhanced compared to the current 4G/LTE standard. Furthermore, signaling efficiencies should be enhanced and latency should be substantially reduced compared to current standards.
