SYSTEMS, METHODS, AND DEVICES FOR UNMANNED VEHICLE DETECTION
Systems, methods, and apparatus for detecting UAVs in an RF environment are disclosed. An apparatus is constructed and configured for network communication with at least one camera. The at least one camera captures images of the RF environment and transmits video data to the apparatus. The apparatus receives RF data and generates FFT data based on the RF data, identifies at least one signal based on a first derivative and a second derivative of the FFT data, measures a direction from which the at least one signal is transmitted, analyzes the video data. The apparatus then identifies at least one UAV to which the at least one signal is related based on the analyzed video data, the RF data, and the direction from which the at least one signal is transmitted, and controls the at least one camera based on the analyzed video data.
Wireless device capable of transmitting uplink sounding reference signals
A user equipment (UE) is disclosed. The UE includes a receiver and a processor that receive a radio resource control (RRC) signal including uplink (UL) sounding reference signal (SRS) configuration information. The UE also receives a semi-persistent scheduling (SPS) message to activate transmission of UL SRSs The UE may then transmit UL SRSs in a time and frequency pattern based on at least the UL SRS configuration information. A UE method and an eNode-B are also disclosed.
Sound source distance estimation
An apparatus for generating at least one distance estimate to at least one sound source within a sound scene comprising the least one sound source, the apparatus configured to: receive at least two audio signals from a microphone array located within the sound scene; receive at least one further audio signal associated with the at least one sound source; determine at least one portion of the at least two audio signals from a microphone array corresponding to the at least one further audio signal associated with the at least one sound source; determine a distance estimate to the at least one sound source based on the at least one portion of the at least two audio signals from a microphone array corresponding to the at least one further audio signal associated with the at least one sound source.
Device and method to improve horizontal and vertical positioning accuracy
User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.

Imaging-based frequency receiver device calibration
A method for calibrating a frequency receiver device (FRD) includes obtaining an image of a visually unique object having a visually unique pattern, the visually unique object disposed at a known location; detecting a match by comparing the pattern to a list of pre-determined patterns; upon detecting a match, determining a relative location of the FRD from the pattern based on the pattern and a new broadcast frequency of a frequency originator device (FOD) from a lookup table correlating a plurality of patterns, their corresponding known locations and a broadcast frequency of at least one corresponding FOD for each of the plurality of patterns and determining the location of the FRD from the FOD based on the relative location of the FRD from the known location of the pattern; and synchronizing a clock of a FRD and a clock of a FOD based on said new frequency of the FOD.
Positioning in wireless communication systems
A method for reporting positioning data from a node B in a cellular communication system comprises performing (210), in a node B, of a measurement of a time of radio signal propagation concerning signalling with a first user equipment within a coverage of the node B. The measurement gives a time value. The time value is coded (212), in the node B, as a multi-symbol time report sequence. Auxiliary positioning information data concerning the first user equipment is obtained (214) in the node B. At least one symbol of the multi-symbol time report sequence is modified (216) (218) in the node B, for representing the auxiliary positioning information data. The modified multi-symbol time report sequence is reported from the node B. A positioning method, a node B and a positioning node are also disclosed.
