  • Patent number: 11496382
    Abstract: Disclosed herein are systems and methods for recording a routing path within a network packet. In particular, the embodiments provide a mechanism to modify a payload of a network packet to include a hop identifier that uniquely corresponds to the computing device on both a forward path and a return path. The system is configured to return the network packet if an ingress address of the computing device matches a destination address of the network packet. Accordingly, in certain embodiments, a single network packet records in the payload a forward path and return path of the network packet through the network. The solution is inexpensive, simply implemented, and easily executed without relying on new hardware and/or software applications executed at an origin computing device.

  • Patent number: 11486957
    Abstract: A device and method for improving the accuracy of angle of arrival and departure computations is disclosed. The device and method rely on manipulation of the antenna switching pattern to achieve an improved calculation of arrival angle. In one embodiment, the device calculates an estimate angle of arrival using conventional methods. The device then determines which of a plurality of different antenna switching pattern yields the more accurate results at this estimated angle of arrival. The AoA measurement is then repeated using the preferred antenna switching pattern. In another embodiment, the device captures the amplitude and/or phase of the signal from each antenna element. The device then sorts these antenna elements and defines a preferred antenna switching pattern based on the sort list. The AoA measurement is then performed using the preferred antenna switching pattern. In another embodiment, neural networks may be utilized to determine the preferred antenna switching pattern.

  • Patent number: 11483095
    Abstract: Hybrid automatic repeat request (HARQ) configurability on new radio (NR) unlicensed (NR-U) operations is disclosed. Time varying code block group (CBG) granularity may be defined by signaling a set of available CBG granularities to a user equipment (UE) for HARQ feedback. The UE monitors for control signaling that may be used to select the CBG granularity for the current slot. The UE may then perform HARQ feedback according to a format corresponding to the selected CBG granularity. Additional aspects disclose updating a contention window size (CWS) in NR-U operations considering the varying CBG granularity. A base station may compute an effective HARQ feedback value that accounts for the varied CBG granularity corresponding to transmissions at a configurable reference slot of set of slots. The base station will update the CWS depending on the relationship of the failure rate of the effective HARQ feedback and a transmission failure rate threshold.
