  • Publication number: 20200241106
    Abstract: Methods and devices for performing hybrid fingerprinting/observed time difference of arrival (OTDOA) positioning are described. Fingerprinting information can be used to improve OTDOA results by using the fingerprinting information to generate OTDOA assistance information. The OTDOA assistance information is sent to a user equipment, which uses the OTDOA assistance information to perform reference signal time differences (RSTDs) measurements.

  • Patent number: 10721015
    Abstract: A Radio Network Node (RNN) and a method for enabling an improved reception of Positioning Reference Signals (PRSs) at a communications device. The RNN and the communications device are operable in a wireless communications network. The RNN selects a first precoder and a second precoder for forming a first beam and a second beam, respectively, and obtains a precoding switching pattern relating to when the first precoder is to be applied to one or more first PRS symbols and when the second precoder is to be applied to one or more second PRS symbols. Further, the RNN transmits, to the communications device, the one or more first PRS symbols to which the first precoder is applied; and in accordance with the obtained precoding switching pattern, the RNN transmits, to the communications device, the one or more second PRS symbols to which the second precoder is applied.

  • Patent number: 10708881
    Abstract: A method, apparatus, and system are provided for facilitating positioning based on signal correlation function characteristic feedback. In an embodiment, the method may involve steps performed by a network node in communication with a wireless communication device (WCD) and a plurality of base stations. The network node receives, from the WCD, location information including position reference signal (PRS) correlation function characteristics of a cross-correlation between a received downlink signal and a transmitted PRS for each base station from the plurality of base stations. The network node determines a position of the WCD using the PRS correlation function characteristics. The WCD may initiate the transmission of the PRS correlation function characteristics on its own, or in response to a request to do so from the network node.

  • Patent number: 10673485
    Abstract: A method and a receiving node for determining Time Of Arrival (TOA) for a radio signal received from a transmitting node in a wireless network. The receiving node detects the received radio signal by cross-correlating the received radio signal with a predefined reference signal transmitted by the transmitting node, to obtain a Cross-Correlated Function (CCF). The receiving node then estimates a set of candidate TOAs for respective signal components of the cross-correlated signal, and determines a final TOA for the received radio signal based on the set of candidate TOAs.

  • Publication number: 20200142487
    Abstract: The disclosure relates to systems and methods of providing haptic feedback based on media content and one or more external parameters used to customize the haptic feedback. The system may modify or otherwise alter haptic feedback that is determined using the media content alone. In other words, the system may use both the media content and the external parameters to determine haptic feedback that should be output to the user or others. The external parameters may include, for example, sensor information, customization information, and/or other external parameters that may be used to customize the haptic feedback.

  • Patent number: 10620707
    Abstract: Systems and methods for interfaces featuring surface-based haptic effects are described. One described system includes a sensor configured to detect a touch in a touch area when an object contacts a touch surface. The touch surface may correspond to the display area or may correspond to a non-display surface of a computing device or peripheral interfaced to a computing device. The system can further include an actuator in communication with the processor and coupled to the touch surface, the actuator configured to output a haptic effect and a processor configured to select a haptic effect to generate. The haptic effect can be selected based on a position of the touch and recognizing an input gesture provided by the touch and/or content displayed in a graphical user interface at a location mapped to a position in the touch area at or near the touch. The haptic effect may provide a texture, simulate an obstacle, and/or adjust the coefficient of friction of the surface.
