  • Patent number: 11025384
    Abstract: The described techniques provide for mapping one or more demodulation reference signal (DMRS) patterns to one or more available channel state information reference signal (CSI-RS) resources. A UE receiving DMRS and CSI-RS signals may determine CSI-RS resources, or reduce its search space for identification of CSI-RS transmissions, based on a DMRS pattern for a transmission. In some cases, a base station may transmit DMRS patterns and a mapping between DMRS patterns and CSI-RS resources to a UE. CSI-RS resources may be configured semi-statically or dynamically by a base station. In some cases, one or more null DMRS patterns may be configured and mapped to CSI-RS resources, and a base station may use a null DMRS pattern for one UE to transmit a DMRS to a different UE, and both UEs may measure channel state information based on an associated CSI-RS transmitted in mapped CSI-RS resources.

    Abstract: A system includes a set of spatially separated transmit antenna elements (SSTAE) broadcasting uniquely identifiable waveforms, a set of spatially separated receive antenna elements (SSRAE) and at least one circuit assembly. The at least one circuit assembly is electrically coupled to the SSRAE, which provide respective electrical signals responsive to the uniquely identifiable waveforms. The electrical signals include at least one target signal and electromagnetic interference. The circuit assembly operates on the electrical signals to create a matched projection space parallel to a reference related to the at least one target signal and a second projection space that is orthogonal or nearly orthogonal to the matched projection space. The second projection space includes the electromagnetic interference but not the at least one target signal. The circuit assembly uses the second projection space and the matched projection space to separate the electromagnetic interference from the at least one target signal.

    Abstract: A mechanism to control transmission by a base station, which may help to control interference on an adjacent frequency. The base station is configured to operate on a first frequency and is equipped with a number of antennas enabled for transmission on the first frequency. Upon detecting of a trigger for reducing potential interference on the adjacent frequency, the base station reduces the number of its antennas that are enabled for transmission on the first carrier, which may reduce the overall energy of the base station's transmission and may thereby reduce interference on the adjacent frequency. In an example implementation, the base station could disable a proper subset of its antennas from use for transmission on the first frequency, while leaving a remainder of its antennas enabled for transmission on the first frequency.

  • Patent number: 10816984
    Abstract: In one embodiment, sensor data are collected from one or more sensors mounted on an autonomous driving vehicle (ADV) while the ADV is moving within a region of interest (ROI) that includes a number of obstacles. The collected sensor data are operated on to obtain obstacle data associated with the obstacles, location data, and a number of timestamps that correspond to the obstacle data and the location data. For each of the timestamps, positions of the obstacles are mapped to some of the obstacle data that correspond to the timestamp based on the location data, thereby generating mapped information of the obstacles. The mapped information is automatically labelled to generate labelled data, where the labelled data is utilized to subsequently train a machine learning algorithm to recognize obstacles during autonomous driving of an ADV.

  • Patent number: 10819616
    Abstract: System and method for testing transmission and reception performance of a data packet signal transceiver device under test (DUT). Data packet signals transmitted by a tester with a tester transmit output power (TTOP) contain trigger frames that include data corresponding to a reported tester transmit power (RTTP) of the data packet signals, and a desired received signal strength (TRSS) of DUT data packet signals to be received by the tester. Based on received signal strength of the tester data packet signals reported by the DUT (DRSS), responsive DUT data packet signals having a DUT transmit output power of RTTP?DRSS+TRSS. Successive repetitions of such tester and DUT data packet signals for multiple combinations of values of the TTOP, RTTP and DRSS enable testing transmission and reception performance of the DUT, including determining minimum and maximum DUT transmission power levels, with minimal signal interactions between tester and DUT.

  • Patent number: 10812995
    Abstract: Methods and systems are described herein for optimized selection of wireless communications networks when multiple wireless communications networks are available to or for selection by a wireless communications device. A wireless communications device may select an optimal network on a per-application and/or per-transmission basis based on one or more policies defined and managed by the device and/or based on dynamic selection of a wireless network based on one or more probed network characteristics (e.g., latency, cost of traffic, data security, etc.). When a state of the device satisfies conditions specified by the policies managed and enforced on the device (e.g., in an enterprise mobility management system), then the wireless network may be selected as defined by the applicable policy. However, when the state of the device does not match an existing policy, then wireless network selection may be based on the dynamic probing of the various networks to determine a preferred wireless network.
