摘要： Disclosed are some examples of techniques for positioning of a user equipment (UE) using positioning reference signal (PRS). One or more units of messages may be communicated between an initiator UE and a responder UE. A unit of message may include a pre-PRS message, a PRS message and a post-PRS message. The pre-PRS message and the post-PRS message may be sent or received using a license spectrum. The PRS message may be sent or received using an unlicensed spectrum. The communication between the initiator UE and the responder UE may be initiated by the initiator UE identifying the responder UE from a plurality of UEs based on positioning properties of the responder UE. The positioning properties of the responder UE may include one or more of a direction, a velocity, a location confidence and a location of the responder UE.

摘要： A method for allowing one or both of a first wireless communications device and a second wireless communications device to determine an estimate of a distance between the first and second wireless communication devices, the method comprising while operating in a first mode of operation, receiving by the second wireless communications device a first type signal as a beacon signal requesting the second wireless communications device to transmit a second type signal, the beacon signal transmitted by the first wireless communications device, in response to receiving the beacon signal, the second wireless communications device transmitting the second type signal, the second type signal being a first synchronisation signal and indicating that the first wireless communications device is to transmit a second synchronisation signal, determining a first time at which the first synchronisation signal is transmitted, and operating in a second mode of operation in which the first device monitors for a second type signal transmitted by the first wireless communications device in response to the first synchronisation signal. The method further comprises receiving a second synchronisation signal transmitted by the first device, and determining a second time at which the second synchronisation signal is received, wherein one or both of the first wireless communications device and the second wireless communications device are able to determine the estimate of the distance between the first and second wireless communications devices, the estimate of the distance based on a first duration and a second duration, the second duration being a time period between the first time and the second time, the first duration being a time period between a third time and a fourth time, the third time being a time at which the first wireless communications device received the first synchronisation signal and the fourth time being a time at which the first wireless communications device transmitted the second synchronisation signal.

摘要： It is described a distance measuring system (200) including: a plurality of mobile devices (100) in UWB technology and each having a computing and control module (1) and a radio transceiver module (2); the plurality of mobile devices (100) includes one initiator mobile device (Device 0) and responder mobile devices (Device 1-Device 3). The initiator mobile device (Device 0) is configured to request message exchange with the responder mobile devices (Device 1-Device 3) so that each responder mobile device (Device 1-Device 3) calculates a distance value to the initiator mobile device (Device 0) based on a flight time measurement. Moreover, the initiator mobile device (Device 0) and/or the responder mobile device (Device 1-Device 3) includes a warning device (4) configured to generate a warning signal when this distance value is below/ over a fixed threshold value. The system is characterised by the fact that the calculation and control module (1) of each mobile device (100) is configured to dynamically change the role of the corresponding mobile device (100) between an initiator role and a responder role so that each mobile device (100) can selectively assume the initiator role to request the exchange of messages with mobile devices having the responder roles and obtain the calculation of the respective distance values.

摘要： Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) transmits an uplink reference signal towards a first reconfigurable intelligent surface (RIS) associated with at least one base station, receives, from the first RIS, a reflection of the uplink reference signal, wherein at least one transmission parameter of the reflection identifies the reflection as the reflection of the uplink reference signal, and enables a distance between the UE and the first RIS to be calculated based, at least in part, on a transmission-to-reception (Tx-Rx) time difference measurement for the UE, the Tx-Rx time difference measurement representing a difference between a transmission time from the UE of the uplink reference signal to the first RIS and a reception time at the UE of the reflection of the uplink reference signal from the first RIS.
