A method and apparatus for estimating a position of a terminal is provided. The method and apparatus include a technique for a sensor network, a machine to machine (M2M), a machine type communication (MTC), and Internet of things (IoT), and may be used for intelligent services based on the technique (smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail industry, and security and safety related services). The method includes identifying direction information of a received signal if setting up connection between a terminal and an access point (AP), receiving information about a barometric pressure sensor from the terminal, and calculating the position of the terminal based on the direction information and the information about the barometric pressure sensor of the terminal.

Systems, methods, and apparatuses are presented for performing parallel uplink wireless signal measurements (UL measurements), in which a signal measuring apparatus determines information on UL measurements being performed or to be performed by the signal measuring apparatus over a predetermined measurement period. The signal measuring apparatus further determines a capability of the signal measuring apparatus to perform parallel UL measurements. The signal measuring apparatus may adjust a measurement requirement or a measurement resource based on a comparison of the UL measurements being performed or to be performed over the measurement period with a capability of the measuring apparatus to perform parallel measurements. The signal measuring apparatus performs the UL measurements based on the adjusted measurement requirement or adjusted measurement resource.

A super regenerative receiver detection system and method that includes a computing system that stores and executes a cross modulation correlation component to modulate a radio-frequency (RF) stimulation signal that is transmitted in an area using a modulating signal having a first modulating mode, and receive a response UEE signal from the area in which the response UEE signal includes a cross modulated signal emitted from a super regenerative receiver (SRR). The cross modulated signal having a second modulation mode that is different from the first modulation mode. Using this information, the cross modulation correlation component processes the received UEE signal to determine a cross modulation correlation level of a cross modulation signal relative to the modulating signal, and generates an alert signal when the determined cross modulation correlation level exceeds a specified threshold.

A signal transmitted from a mobile device is received at a device. A change in angle-of-arrival (AoA) of the signal is computed as the mobile device moves from a first location to a second location. A first distance and a second distance of the mobile from the device corresponding to the first and second locations, respectively are computed. A displacement of the mobile device from the first location to the second location is computed based on mobility information provided by a sensor of the mobile device. A change in an angle of direct path (ANDP) of the signal is computed based on the first distance, the second distance, and the displacement. The ANDP is determined based on a comparison of the change in AoA to the change in ANDP.
