  • Patent number: 10893471
    Abstract: A communication system includes a base station configuring an energy saving cell (ES cell) and a base station configuring a compensation cell (Comp cell). The ES cell is switchable between a switch-on state and a switch-off state. The Comp cell compensates for the coverage of the ES cell when the ES cell is in the switch-off state. Before the Comp cell starts compensating for the coverage, for example, before the ES cell decides to switch itself off in Step ST2101, in Step ST2201 for example, the base station configuring the ES cell notifies the UE being connected with the ES cell of the information about a Comp cell, for example, a Comp cell list.

  • Patent number: 10845454
    Abstract: An apparatus obtains results of measurements, which are performed by a mobile device on signals of communication nodes. The measurement results for each of the communication nodes include a signal strength related value and an identification of the communication node. The apparatus obtains for one of the communication nodes a stored indication of a location and a stored signal strength related value and determines a difference between measured and stored signal strength related values. The apparatus estimates the position of the mobile device based on the results of measurements and on obtained stored radio model data. In the case that the determined difference for the at least one communication node falls short of a predetermined threshold, the apparatus determines a distance between estimated position and indicated location for the at least one communication node, as an indication of a health state of stored radio model data.

  • Patent number: 10412541
    Abstract: A real-time location system (RTLS) having tags, bridges, bay-level event sensors and a location engine for use in determining the bay location of tags, To determine which bay a tag is in, bay-level event sensors sense motion events in the bay, transmit the motion event reports to a location engine, and/or tags. Tags contain an accelerometer, to sense motion of the tags. A series of location-engine steps estimates the bay-level-location of the tags based on a combination of received signal-strength analysis, and a comparison of tag-motion status to the perceived motion events in a bay. The analysis of tag-motion status and motion-in-bay events produces a better estimate of bay-level location of the tag than a received-signal-strength estimate can produce alone.

  • Patent number: 10162177
    Abstract: A method and apparatus for self-relative body tracking in virtual reality systems using magnetic tracking is disclosed, which allows more accurate tracking of a user's body relative to the user's field of vision. A head-mounted magnetic tracking (HMMT) system is used, in which other parts of a user's body are tracked relative to the HMD on the user's head, rather than relative to a base station. This results in less distortion of the magnetic field used for tracking and thus allows for more accurate determination of the position and orientation of a user's body parts relative to the user's field of vision, so that a more accurate avatar may be presented on the HMD to the user. This allows the avatar of the user's body part to be shown in a location that corresponds closely to its physical position. In an alternative embodiment, multiple portions of the user's body may be tracked.

  • Patent number: 9825737
    Abstract: The detection and validation of Secondary Synchronization Signal comprising generating a set of samples by performing DFT operation on a time domain LTE signal, wherein the signal comprising an LTE frame divided into an even half and odd half frame, First and second set of hypotheses from even samples in even and odd half frame are generated and third and fourth set of hypotheses from odd samples in even and odd half frame are generated using first and second hypotheses. Even half frame is selected as start of boundary of the frame when location of the peak of first hypotheses is smaller than that of second hypotheses or location of the peak of fourth hypotheses is smaller than that of third hypotheses. The physical layer cell identity is determined from the locations of the peak of the first, second, third and fourth set of hypotheses averaged over multiple frames.

  • Patent number: 9733337
    Abstract: Techniques are discussed for conveying frequency error characteristics for a plurality of cell transceivers from a server to a mobile device to enable the mobile device to determine an optimum or near optimum period of coherent integration of a downlink signal from one or more of the plurality of cell transceivers based on the frequency error characteristics. The coherent integration of the downlink signal may be to support a downlink terrestrial positioning method such as the Observed Time Difference of Arrival (OTDOA) method for Long Term Evolution (LTE) and the downlink signal may be a Positioning Reference Signal (PRS). A mobile device may perform downlink signal integration for longer periods than the optimum period for coherent integration by combining coherent integration results using non-coherent integration. The optimum period may achieve maximum or near maximum signal to noise ratio.
