  • Patent number: 11588529
    Abstract: Beam management enhancements for advanced millimeter wave (mmWave) operations are disclosed. As a part of channel state information (CSI) reporting configuration, a user equipment may include an interference plus noise measurement of beams for consideration in beam management. The UE measures a set of signaling resources of each beam for power contribution and interference plus noise. According to the particular configuration, the UE may rank all of the available beams into a subset of the highest ranked beams, ranked either by the interference plus noise measurement, by the power contribution metric, or by a combination of both. The UE reports an identification of the subset to the serving base station which determines the beam to use for subsequent communications with the UE.

  • Patent number: 11573314
    Abstract: The invention discloses an ultra-wideband (UWB) positioning system, UWB base stations (BSs), UWB tags and the operation methods thereof. Because the present invention uses a server aware of the positions of all BSs to determine the BSs that performs distance measurement, and the server assigns different time slots to each BS that performs distance measurement, the present invention can avoid collisions between the BSs in the process of distance measurement. Furthermore, because the tag can select a specific time slot to access the UWB positioning system by monitoring the UWB signals in the air, the present invention can reduce collisions between the tags. By carefully planning the system frames and subframes of the time division multiplexing system, and sophisticatedly arranging the operation timings of the BSs and the tags, the present invention provides practical and stable UWB positioning system, BSs, and tags.

  • Patent number: 11558714
    Abstract: A user equipment (UE) initiates a positioning session based on ranging in a distributed system of UEs. The positioning session includes a plurality of anchor UEs with known positions that provide information including ranging information and their positions to the initiator UE in post-ranging messages. The initiator UE identifies anchor UEs that provide information that does not significantly contribute to the final position estimate for the initiator UE. The initiator UE, for example, may generate position estimates and associated accuracy levels for different subsets of anchor UEs and may use the accuracy levels to identify a subset of anchor UEs that may be used for positioning in place of the full set of anchor UEs without a significant loss of accuracy. Selected UEs are excluded from providing post-ranging messages in subsequent positioning sessions to reduce signaling overhead and improve efficiency.

  • Patent number: 11528584
    Abstract: A method for performing contact tracing. An analysis system performing the method receives geo-temporal data comprising location data points for various wireless terminals, including the wireless terminal being used by a person diagnosed as having a specified disease and the wireless terminals of people who possibly have come in contact with the infected person. Based on filtering the geo-temporal data, the analysis system generates relatively-condensed mobility profiles that are representative of each person's locations and movements, and analyzes the mobility profiles. Through careful selections of various parameters based on the disease that is being analyzed, the mobility profiles are used instead of the relatively large amounts of geo-temporal data, to represent users of wireless terminals and to determine their interactions in regard to disease transmission.

  • Patent number: 11516624
    Abstract: An indoor location positioning system comprises at least one processor, Wi-Fi scanners, and a RSSI fingerprint database. The Wi-Fi scanners and the RSSI fingerprint database works with the processor. The Wi-Fi scanners are positioned at locations within an environment that is partitioned into interconnected zones. The Wi-Fi scanners receive anonymous probe messages from Wi-Fi devices that are present in the environment during a calibration phase of the indoor location positioning system. The RSSI values are collated to create RSSI fingerprints corresponding to the different locations respectively. One or more of the Wi-Fi scanners are used as anchor scanners to counter the difference in transmit power levels of different Wi-Fi devices that result in different RSSI fingerprints for the different types of Wi-Fi devices, wherein the RSSI value at each anchor scanner is subtracted from the RSSI values at rest of the Wi-Fi scanners to generate the RSSI fingerprint.

  • Patent number: 11510028
    Abstract: Techniques for performing high-precision presence detection by establishing and monitoring peer-to-peer communication links between user devices residing in a same physical environment. A user device that resides in the environment may establish communication links with multiple other user devices residing in the environment. The user device may monitor the channel properties for those communication links to detect fluctuations in the channel properties caused by a user moving through a signal of the communication links. In examples where the user device detects fluctuations in channel properties for multiple communication links, the user device may determine that the user had moved though signals of the communication links. The user device may determine that, because the user moved through signals of multiple communication links, the user may be in close proximity to the user device, such as in the same room.

  • Patent number: 11502890
    Abstract: A system and method are provided for processing symbols for transmission. The method involves producing a single carrier offset quadrature amplitude modulation (OQAM) waveform signal from a set of K complex symbols. The method further involves pulse shaping 2K frequency domain samples of the OQAM waveform signal with J non-zero coefficients, where the J non-zero coefficients represent a frequency response of a conjugate symmetrical pulse shape, and K?J?2K?1. The approach has the advantage of avoiding self-interference, with the result that better BLER performance may be possible. The approach is applicable to any modulation order and also avoids bandwidth expansion. Flexibility is provided through a trade-off between PAPR vs. spectrum efficiency.
