Aspects presented herein may enable a network node (e.g., a UE, a TRP/base station) to provide its beam squint information and/or to receive beam squint information of another positioning entity to improve the accuracy and reliability of UE positioning. In one aspect, a network node obtains beam squint information associated with a set of beams of the network node under a plurality of center frequencies. The network node transmits, for a network entity, the beam squint information for at least one beam of the set of beams for a positioning session. The network entity participates, based on the beam squint information via the at least one beam, in the positioning session with the network entity.

Implementations of the present disclosure relate to a system comprising an access point (AP), an antenna module and a radio cable. The AP includes a modulator configured to receive a clock signal and a power voltage and modulate them into a modulated power. The radio cable is configured to transmit the modulated power. The antenna module comprises a directional antenna, a demodulator configured to demodulate the modulated power into a demodulated clock signal, and a sensor configured to receive the demodulated clock signal and the modulated power. With the system of the present disclosure, the compass/declinometer sensors can be deployed on the panel antenna, so as to obtain the location, the direction and the coverage of the panel antenna. Further, the radio frequency cables can be used to transmit the power and clock signal between the sensor and the AP, and there is no need to provide dedicated cables.

A light source emits a modulated light, and a radio-frequency transceiver disposed therewith emits a radio-frequency signal. A mobile device may receive either or both signals and determine its position based thereon. The light and radio-frequency sources may be disposed in node in a network of said sources, and the nodes may communicate via the radio-frequency transceivers.

The various embodiments herein provide a Uniform Circular Displaced Sensor Array (UC-DSA) system and method for measuring/estimating Direction of Arrival (DOA) of a wireless signal. The UC-DSA system comprises at least a set of two circular antenna arrays. The two circular antenna arrays have a number of elements. A Radio frequency (RF) receiver captures a wireless signal incident on a circular antenna array. A Direction of Arrival (DOA) estimator processes a received input signal and a Triangulation system provides the exact location of the source of the wireless signal. The two circular antenna arrays with the same number of elements are placed on different radii, and are shifted to have equal separation between inner elements and outer elements.
