The disclosure provides various methods and apparatus useful for mapping wireless nodes using a drone and aligning the body of the drone with an antenna of the wireless node. A method includes mapping, by an apparatus, a space including one or more locations of one or more wireless nodes, determining whether the apparatus is in proximity to a first wireless node of the one or more wireless nodes, determining an orientation of an antenna of the first wireless node, and in response to determining that the apparatus is in proximity to the first wireless node and determining the orientation of the antenna of the first wireless node, adjusting a six-degree-of-freedom (6DoF) orientation of the apparatus based on the determined orientation of the antenna of the first wireless node. The apparatus may be an autonomous drone.

A method includes: receiving a ranging signal from the transmitter comprising a set of multiplexed sub-signals, each multiplexed sub-signal characterized by a frequency in a set of frequencies; calculating a time-based time-of-arrival estimate based on the series of time-domain samples of the ranging signal; calculating a time-based uncertainty of the time-based time-of-arrival; for each sub-signal pair in a subset of multiplexed sub-signals of the set of multiplexed sub-signals, extracting a phase difference of the sub-signal pair; calculating a phase-based time-of-arrival estimate based on the phase difference of each sub-signal pair in the subset of multiplexed sub-signals; calculating a phase-based uncertainty of the phase-based time-of-arrival estimate; and calculating a hybrid time-of-arrival estimate as a weighted combination of the time-based time-of-arrival estimate, the phase-based time-of-arrival estimate, based on the time-based uncertainty and the phase-based uncertainty.

The present disclosure provides a communication device for wireless communication systems and a communication method for the communication device. The communication device includes: one or more processors, configured to determine information of a reference geographical location used for the communication device, and generate, based on the information of the reference geographical location and a current absolute geographical location of the communication device, information of a relative geographical location of the communication device with respect to the reference geographical location; and a communication unit, configured to transmit the information of the relative geographical location to a predetermined communication object.

Timing advance (TA) handling for sidelink (SL)-assisted positioning of a first user equipment (UE), comprises determining the first UE is configured to transmit an SL positioning reference signal (SL-PRS) to a second UE for the SL-assisted positioning. A guard period length can be determined based on a configuration of the first UE for transmitting the SL-PRS, where the guard period may comprise a period of time during which the SL-PRS is transmitted by the first UE. A message can be sent to a serving transmission reception point (TRP) of the first UE, where the message indicates the guard period and comprises a TA-related request. The TA-related request includes a request to postpone applying a TA command received by the first UE until after the guard period, or a request for the serving TRP not to send a TA command to the first UE during the guard period

Embodiments provide a location information obtaining method and a device, and relates to the communications field. The method includes: obtaining, by a network device, location information of a reference point and location information of first user equipment; determining, by the network device, relative location information of the first user equipment relative to the reference point; and sending, by the network device, the location information of the reference point and the relative location information of the first user equipment relative to the reference point.

Information sharing methods and apparatuses are disclosed. A request for information sharing is sent by a requesting client terminal and is received at a server; a geographic position of the requesting client terminal is determined; an associated client terminal is identified based on a geographic proximity to the requesting client terminal; and an information sharing session is implemented between the requesting client terminal and the associated client terminal.

Method and a network node (110, 910) for enabling position determination of a measurement performed by a user equipment (120) served by a base station (110). The user equipment (120) and the base station (110) are comprised in a cellular communications network (100). A measurement report comprising measurement data associated with the measurement and a time of measurement thereof is received (301, 801) from the user equipment (120). One or more first type of data associated with the user equipment (120) at a respective point in time are retrieved (302, 802), which first type of data is localization corresponding data. Based on the time of measurement, first type of data that corresponds to the time of measurement is determined (303, 803) from the retrieved one or more first type of data. The determined first type of data is associated (304, 804) with the measurement data. The position of the measurement may then be determined based on the first localization corresponding data associated with the measurement data.
