A radio communication terminal (UE2) configured to act as a radar receiver, comprising: —a radio transceiver (323), —logic (320) configured to communicate data, via the radio transceiver, on a radio channel (101), wherein the logic is further configured to obtain (233), via the radio transceiver, a radar probing request (230) to detect radio signal echoes; determine (235) a receive direction (Dir2) based on the request; control the radio transceiver to detect (242) a receive property of the radio signal echoes in said direction; and transmit (261), via the radio transceiver, data (260) associated with the detected receive property to a radio communication device (BS1, UE1).

An electronic device according to various embodiments of the present disclosure may include a plurality of antenna arrays and at least one processor operatively connected to the plurality of antenna arrays. The at least one processor may transmit a first radio signal including a specific polarization, generated through a first antenna array of the plurality of antenna arrays. The at least one processor may receive a second radio signal which is a reflected signal of the first radio signal and includes the specific polarization, generated through a second antenna array different from the first antenna array of the plurality of antenna arrays. The at least one processor may identify external objects around the electronic device on the basis of the second radio signal. Other various embodiments may be possible.

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.
