摘要： A method using a UWB for precisely positioning in an environment without a positioning infrastructure is provided. The method, when positioning objects of swarm objects in a free space, etc., calculates an object position of each object through cooperation with objects existing surrounding. In this state, positioning is simply performed without a specific anchor by defining objects as anchors in a UWB in accordance with an embodiment. In particular, cooperative positioning is quickly performed by reducing position errors of objects in accordance with pull-push relationships based on UWB TWR. Therefore, when a specific mission is performed in an environment in which a positioning infrastructure does not exist or is lost, such as a flight space, positioning is performed in the UWB-based cooperative positioning method described above, whereby precise positioning suitable for these environments is provided.

摘要： The invention relates to a system (1) for positioning at least one mobile receiver (2), comprising at least two stationary transmitter bases (4, 4A, 4B). Each transmitter base 5 (4, 4A, 4B) is configured to transmit radio frequency signals (S1A, S1B, sdA, sdB, srA, srB) and to transmit a sum (S1A, S1B) of at least two unmodulated pure carrier signals of different frequencies; and the mobile receiver (2) further comprises: means for measuring phases of the signals; and computing means configured to: apply a Fourier transform to a signal consisting of the various measured phases of the radio frequency 10 signals; determine a time-of-flight between the mobile receiver (2) and each base (4A, 4B); calculate at least one time-of-flight difference between the mobile (2) and two transmitter bases (4A, 4B); determine the position of the mobile receiver (2) from the calculated time-of-flight difference(s).

摘要： Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

摘要： A process to partition a video feed to segment live player activity includes receiving, on a first recurring basis, a transmission of a central video feed from a first camera. The central video feed is calibrated against a spatial region represented in at least two dimensions that is encompassed by the central video feed. The process includes receiving, on a second recurring basis, a respective time-stamped position information from each tracking device in a plurality of tracking devices. Each tracking device is worn by a corresponding subject on the spatial region and transmits positional information that describes a time-stamped position of the corresponding subject in the spatial region. The process uses the received information and the calibration to define a first sub-view of the central video feed associated with a first subject. The first sub-view comprises a corresponding sub-frame associated with the first subject.

摘要： A method for the determining a position of at least one measurement object equipped with a mobile station having a receiver includes employing at least four reference objects having a base station and a transmitter, wherein a first reference object of the at least four reference objects has a mobile station with a receiver and simultaneously acts as a measurement object. The base station and the mobile station are structurally combined. The reference objects initially have a known position that can change. The transmitters of the base stations transmit signals and the mobile stations receive signals. The method additionally includes emitting, by at least two transmitters of base stations, periodic signals of different frequencies at mutually defined time intervals, wherein these frequencies are closely adjacent.
