Abstract: A terminal device first authenticates whether the terminal device has permission to sense a to-be-measured object. If the terminal device has sensing permission, the terminal device senses the to-be-measured object. If the terminal device has no sensing permission, the terminal device does not sense the to-be-measured object. In this way, privacy leakage of the to-be-measured object is prevented.

Abstract: An exemplary communications system includes a first base station and a second base station. The first base station transmits a first signal to the second base station, and the second base station receives the first signal and transmits a second signal in response. The first base station receives the second signal and transmits a third signal in response. A receiving unit of a device receives the first, second, and third signals. The device measures a first delay time between receipt of the first signal and receipt of the second signal, and measures a first round trip time based on receipt of the second signal and the third signal. A second round trip time and a second delay time are determined and a first time difference of arrival is calculated based on the first round trip time, first delay time, second round trip time and second delay time.

Abstract: A method and an apparatus for positioning a terminal device. The method includes: generating, by a terminal device, a first message, where the first message includes one or more pieces of first time difference information, and the first time difference information includes a first time difference and information about a first positioning reference signal pair corresponding to the first time difference, where the first positioning reference signal pair includes a first uplink positioning reference signal and a first downlink positioning reference signal that have an association relationship, and the first time difference is a time difference between a sending time point of the first uplink positioning reference signal and a receiving time point of the first downlink positioning reference signal; and sending, by the terminal device, the first message to a network device.

Abstract: Ultra-wideband (UWB) tags can be used as part of a high-resolution motion capture system that may not require a cost or a complexity that is typically associated with visually based motion capture systems. The UWB based motion capture uses a bundle of UWB tags, which in a possible implementation, can be affixed to body parts of a user to sense motion of the body parts. The absolute positions of each UWB tag can then be determined by reconstructing a skeletal topology from a Euclidean distance matrix based on inter-tag ranging measurements using handshake signals of a UWB protocol.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a first network node performs a reception-to-transmission (Rx-Tx) time difference measurement, the Rx-Tx time difference measurement representing a difference between a reception time of at least one first positioning reference signal (PRS) from a second network node and a transmission time of at least one second PRS to the second network node, and transmits, to a positioning entity, based on a value of the Rx-Tx time difference measurement being greater than a threshold, a measurement report including a first value and a second value representing the value of the Rx-Tx time difference measurement, wherein the first value is a quotient value resulting from dividing the value of the Rx-Tx time difference measurement by the threshold, and wherein the second value is a remainder value resulting from dividing the value of the Rx-Tx time difference measurement by the threshold.

Abstract: Some demonstrative embodiments include apparatuses systems and/or methods of Collaborative Time of Arrival (CToA). For example, an apparatus may include circuitry and logic configured to cause a CToA broadcasting wireless communication station (STA) (bSTA) to broadcast an announcement frame to announce a ranging-to-self sequence of a CToA measurement protocol; to broadcast a first ranging measurement frame of the ranging-to-self sequence subsequent to the announcement frame; to broadcast a second ranging measurement frame of the ranging-to-self sequence subsequent to the first ranging measurement frame; and to broadcast a Location Measurement Report (LMR) frame of the ranging-to-self sequence subsequent to the second ranging measurement frame, the LMR frame including a Time of Departure (ToD) of the first ranging measurement frame.

Abstract: Provided is a secure ranging method capable of blocking access of a malicious user by preventing an attack by the malicious user when ranging is performed using an ultra-wideband (UWB). Also, provided is a method of increasing accuracy of ranging. A method of operating an electronic device for performing ranging by using a UWB in a wireless communication system includes: transmitting and receiving at least one frame for ranging, to and from at least one other electronic device; obtaining a first ranging value and a second ranging value, based on the at least one frame; and performing integrity checking, based on a result of comparing the first ranging value with the second ranging value.
