  • Patent number: 11284338
    Abstract: A base station for a multiple-input, multiple-output (MIMO) array receives a message that includes information identifying the transmitting and receiving nodes. Based on whether the base station has access to up-to-date channel covariance matrices for the nodes, the base station selectively performs a clear channel assessment in an unlicensed frequency band concurrently with placing nulls in directions associated with the nodes. In some cases, the up-to-date channel covariance matrices are used to place nulls in the directions associated with the nodes concurrently with performing the clear channel assessment in response to the up-to-date channel covariance matrices being available to the base station. Placement of nulls in the directions associated with the nodes is bypassed in response to the up-to-date channel covariance matrices not being available to the base station.

  • Publication number: 20210389494
    Abstract: Self-testing proximity testing systems and corresponding methods are discussed herein and can include a proximity probe and controller in electrical communication via a cable. A self-testing subsystem can be in communication with the controller and configured to determine whether proximity probes and cables assembled with a controller are compatible or incompatible. The self-testing subsystem can place a known impedance in electrical communication with the controller, modifying a proximity signal output by the controller. When the modified proximity signal differs from a predicted proximity signal by greater than or equal to a threshold amount, the self-testing subsystem can output a first indication indicating that incompatible proximity probes and cables are assembled with a controller.
