Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described. The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.

The disclosure relates to drone user equipment (UE) indications that may be conveyed to a wireless network. In particular, a UE that has flight capabilities (i.e., capabilities to operate as an unmanned aircraft system) and optional further capabilities to report a current height level may indicate such capabilities to the wireless network. As such, the wireless network may differentiate the drone UE from other UEs that only operate on the ground. Furthermore, the optional current height level may enable the wireless network to differentiate among drone UEs operating at different heights and/or from other UEs that are operating on the ground. The wireless network may further use the information indicating the flight capabilities either alone or in combination with the optional height information to configure power control parameters, manage interference, provide mobility management functions, generate neighbor lists, control beamforming, or implement a radio resource configuration or management procedure.

Systems and methods for determining a location of one or more user equipment (UE) in a wireless system can comprise receiving reference signals via a location management unit having two or more co-located channels, wherein the two or more co-located channels are tightly synchronized with each other and utilizing the received reference signals to calculate a location of at least one UE among the one or more UE. Embodiments include multichannel synchronization with a standard deviation of less than or equal 10 ns. Embodiments can include two LMUs, with each LMU having internal synchronization, or one LMU with tightly synchronized signals.

Sensory information is obtained at a drone (e.g., from sensors at the drone or deployed at other locations), and the sensory information defines the physical operating environment of the drone. The aerial drone is initially operated according to a current geographical location that is received. The sensory information is subsequently obtained, for example, from the sensors. An adjusted current geographical location of the aerial drone is selectively determined based upon an evaluation of the sensory information and a UWB beacon signal. The aerial drone is operated according to the adjusted current geographical location.

A method for determining a distance between a first radio signal transceiver and a second radio signal transceiver using narrowband ranging comprises calculating a preliminary estimate of a value proportional to a one-way frequency domain channel response, based on measurements of signal phase and signal strength; calculating, for pairs of adjacent frequencies, an estimate of a value proportional to a time synchronization offset between a clock used by the first radio signal transceiver and a clock used by the second radio signal transceiver, and determining a final estimate of a value proportional to the one-way frequency domain channel response based on the preliminary estimate and adjacent estimates for the value proportional to the time synchronization offset, where the final estimate is used for the final distance determination.

Systems and methods to position beacons at traffic choke points, use a mobile device to detect the peaks of beacon signals corresponding to the mobile device traveling through the traffic choke points, and thus determine accurately the position and speed of the mobile device in the transport corridor between the choke points. The determined position and speed of the mobile device can be used to improve the performance of other location determination technologies, such as radio frequency fingerprint-based location estimate and/or inertial guidance location estimate.

Aspects presented herein may enable a navigation application of a UE to feed its calculated navigation route information to a PE of the UE to aid the PE computing positioning estimations to improve positioning accuracy. In one aspect, a UE estimates a current location of the UE based on a set of positioning measurements and time update predictions using a positioning engine. The UE calculates real-time navigation route information using at least one navigation application based on the current location of the UE, a destination of the UE, and map information. The UE changes or verifies a set of positioning estimations performed by the positioning engine based on the real-time navigation route information from the at least one navigation application.

The presentment and redemption system offers discounts directly to consumers through their mobile phones. The discounts are based upon the user of the mobile phone meeting a targeting criterion and the discounts are determined using the targeting criterion. Mobile phone users that do not meet the targeting criterion are not eligible for the discount. Because the discounts can be targeted to each individual consumer, there can be a better correlation between consumers' interests and the transmitted discounts.

Systems and methods for determining a location of one or more user equipment (UE) in a wireless system can comprise receiving reference signals via a location management unit having two or more co-located channels, wherein the two or more co-located channels are tightly synchronized with each other and utilizing the received reference signals to calculate a location of at least one UE among the one or more UE. Embodiments include multichannel synchronization with a standard deviation of less than or equal 10 ns. Embodiments can include two LMUs, with each LMU having internal synchronization, or one LMU with tightly synchronized signals.

The detection system monitors WiFi wireless communications at a wireless device and detects a probe request associated with a location. The WiFi device may be a dedicated presence detection device or may offer access to internet and other services as a WiFi access point. A device identifier associated with the originating device may be a component of the probe request. Using the device identifier, the system can detect the presence of a consumer at the location associated with the wireless communications device and transmit information to the consumer based upon the device identifier.
