Techniques are provided for enabling user equipment (UE) positioning based on base station side angle estimation in millimeter wave (mmW) bands. An example method for determining positioning information with a mobile device includes receiving positioning assistance data including beam pattern information for a plurality of reference signals associated with at least two sub-bands, receiving at least one of the plurality of reference signals within a sub-band, and determining an angle of departure value for at least one of the plurality of reference signals based at least in part on the positioning assistance data for the sub-band.

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 electronic apparatus includes: a wireless communication module comprising communication circuitry, a memory storing one or more instructions, and a processor configured to execute the one or more instructions stored in the memory to: receive a wireless signal from an external device through the wireless communication module, obtain identification information of the external device and a signal strength of the wireless signal from the wireless signal, identify whether the obtained signal strength corresponds to a stored signal strength pattern corresponding to the identification information of the external device, and perform an operation corresponding to the identification information of the external device, based on the obtained signal strength being identified to correspond to the stored signal strength pattern.

Radio-Frequency identification (RFID) locationing systems and methods for locating one or more items positioned within a defined space are disclosed herein. An example embodiment includes energizing, by an RFID reader having an RFID antenna, an RFID tag corresponding to an item positioned within a defined space. Each of a first signal strength and a second signal strength of the RFID tag is detected, respectively, by a first RFID receiver node of a first node channel and a second RFID receiver node of a second node channel. A controller alternates a multiplexor to receive at the multiplexor each of first signal strength data from the first RFID receiver node and second signal strength data from the second RFID receiver node. The first signal strength data and the second signal strength data is provided to the RFID reader and combined to determine a location of the item positioned within the defined space.

There is described a floor selection system for location tracking within a structure. A communication component receives sensor data, associated with a beacon received from a tag, from sensors. A processor identifies features based on the sensor data, identifies decision tree stumps arranged in a particular order, assigns weights to the decision tree stumps based on the features and the feature thresholds. The processor further determines whether an aggregate of the weights is greater than a resultant threshold and selects a floor location of the tag based on whether the aggregate of weights is greater than the resultant threshold. The floor location is selected from floor locations of the structure proximal to the sensors.

A direction finding system for radio direction finding of a target emitting at least one signal is described. The direction finding system comprises at least one receiver unit, at least one antenna assigned to the at least one receiver unit and a central processing unit connected to the at least one receiver unit. The at least one receiver unit is configured to measure an absolute receiving power or a relative receiving power of the at least one signal emitted by the target. The central processing unit is configured to determine the power level of the respective power received by the at least one receiver unit. The central processing unit is further configured to determine interpolated constant power contours in order to locate the target. In addition, a method for radio direction finding of a target emitting electromagnetic at least one signal is described.

When deploying or upgrading an enhanced cellular communication system, a site survey may be performed by configuring cellular devices in a given area to report various operational metrics. The devices may also be configured to report environmental data that can be used to determine whether the devices are indoors or outdoors, which may be useful when interpreting the operational metrics. The environmental signatures may include an audio signature, which may comprise an audio impulse response produced by an acoustic echo canceller (AEC) of the device. The environmental signatures may further include a light signature, which may be based on frequency components of ambient light. The environmental signatures may further include an audio signature, which may be based on characteristics of radio signals received by the device. Machine learning techniques may be used, with the environmental signatures as features, to predict whether a given device is indoors or outdoors.
