A tracking system determines a location of a tracking device associated with a user using one or more access points at the location. Each access point at the location is configured to detect and couple with the tracking device when the tracking device is within a communicative range of the access point. An access point provides updates on the tracking device's presence, as well as the tracking device's arrival to and departure from the communicative range of the access point, to a tracking server. The tracking server determines, from these updates, whether the tracking device is at the location. The user may be notified, via a mobile device, of the tracking device's location.

Disclosed by the present application are a positioning method and apparatus, which are used to improve indoor positioning performance and precision without occupying a large amount of system resources. At a positioning server side, a positioning method provided by an embodiment of the present application comprises: acquiring a positioning capability supported by a user equipment (UE), and determining, according to the positioning capability, that the UE may obtain a positioning measurement value by means of detecting a positioning reference signal ioPRS that is used for indoor/outdoor positioning; acquiring positioning auxiliary data comprising ioPRS configuration data, and sending the positioning auxiliary data to the UE; acquiring the positioning measurement value that is provided by the UE and that is acquired on the basis of the ioPRS, and using the positioning measurement value to position the UE.

A system can be used with a drone delivery service that facilitates a service delivery via at least one drone delivery device. The system includes a code generator configured to generate beacon data that identifies a subscriber. A beacon generator is configured to generate a wireless homing beacon that indicates the beacon data, wherein the wireless homing beacon is detectable by the at least one drone delivery device to facilitate the service delivery to the subscriber by the drone delivery device at a location selected by the subscriber and a network interface is configured to communicate via a network. The system receives delivery image data captured after the service delivery by the drone delivery device.

A user device, UE, for a wireless communication system is described. The wireless communication system includes a plurality of user devices, UEs. The UE is to communicate with one or more further UEs using a sidelink, SL. One or more location information elements describe a location or position of a UE, wherein the location information element includes a first part and a second part, wherein, for locations or positions within a certain area, the first part of the location information element is one of a set of fixed first parts and the second part of the location information element varies dependent on the actual or exact location or position of the UE. When being in the certain area, the UE is to receive from the further UE, e.g., using sidelink control information, SCI, position information of the further UE, the position information including some or all of the second part of the location information element of the further UE, and obtain the location or position of the further UE by combining the one of the set of fixed first parts with the position information which is received from the further UE, wherein, in case the set of fixed first parts includes more than one fixed first part, the UE is to select the one of the set of fixed first parts using the position information which is received from the further UE.

A positioning method includes: sending, by a base station, indication information to a plurality of UEs, where the plurality of UEs have an MDT function in a cell covered by a to-be-positioned RRU, and the indication information is used to indicate the plurality of UEs to periodically report location information; obtaining, by the base station within each of at least one time period, time-of-arrival ToA measurement values of N UEs, where the N UEs are some UEs that report the location information in the plurality of UEs, N≥1, and N is an integer; and calculating, by the base station, a location of the to-be-positioned RRU based on M ToA measurement values obtained within the at least one time period and M pieces of location information that are in the received location information and that respectively correspond to the M ToA measurement values, where M≥3, and M is an integer.

The present application relates to correction of position data used in a position information collection system, in which measurement points correspond to position data of a mobile body at respective time points and a movement path of the mobile body connects the measurement points in a time series. When the position data produces a movement path of the mobile body which passes through a not-enterable area, the position data is corrected such that the movement path of the mobile body circumvents the not-enterable area without reducing positioning accuracy, by performing position correction operations which include: determining a crossing status with regard to how the movement path crosses the not-enterable area; counting a number of the measurement points within the not-enterable area; and correcting the position data such that the movement path circumvents the not-enterable area.

An ultra wideband (UWB) dynamic positioning method and a system thereof are provided. A target UWB device detecting step includes driving a host UWB device to detect whether a target UWB device or at least one first-order seeking UWB device is around the host UWB device, and then a detecting result is generated. A host UWB device operation deciding step includes deciding an operating mode of the host UWB device according to the detecting result. When the target UWB device is around the host UWB device, the operating mode includes calculating a moving direction from the host UWB device to the target UWB device. When there is the first-order seeking UWB device around the host UWB device without the target UWB device, the operating mode includes switching on the first-order seeking UWB device to enter a seeking mode.
