  • Patent number: 10659953
    Abstract: Embodiments herein describe pruning a neighbor list sent to a client device using a predefined assignment corresponding to an AP or the client device which can reduce the time required for the client device to roam between APs in a WLAN deployment. The pruned neighbor list serves as a Wi-Fi client steering mechanism to affect which AP the client device chooses when roaming. In one embodiment, a controller uses information regarding fabric nodes in the backend infrastructure to prune the neighbor list to include only the APs that are assigned to the same fabric node as the current AP. In another embodiment, the controller considers a service provider corresponding to the client device when pruning the neighbor lists. The list may include only the neighboring APs assigned to provide Wi-Fi access for the same service provider.

  • Patent number: 10594526
    Abstract: A downlink cellular communication signal processing method includes storing resource elements from multiple resource element sequences into multiple sets of consecutive data bins of a composite signal input grid that also includes guard band bins between the sets of data bins. A frequency-domain to time-domain transformation of all values within the composite signal input grid is performed to produce a sequence of time-domain samples (e.g., a portion of an OFDM symbol). The transformation has a number of points equal to or greater than the number of bins in the multiple sets of data bins and the guard band bins. An uplink processing method includes performing a time-domain to frequency-domain transformation on a sequence of time-domain samples to produce resource elements in multiple sets of consecutive data bins of a composite signal output grid that also includes guard band bins between the sets of data bins.

  • Patent number: 10560950
    Abstract: Embodiments provide a method for sending a signal by user equipment and user equipment. The method includes: within an obtained channel detection cycle, detecting a first interference strength within system bandwidth and a second interference strength on each sub-band within the system bandwidth; comparing the first interference strength with a first interference threshold; if the first interference strength is less than the first interference threshold, selecting, from the system bandwidth according to the second interference strength on each sub-band within the system bandwidth, N first sub-bands that receive relatively small interference; and sending a signal on the N first sub-bands. In consideration of interference within the entire bandwidth and interference to each sub-band, when interference to the entire system is relatively small, a transmission collision is avoided.

  • Patent number: 10554572
    Abstract: Approaches, techniques, and mechanisms are disclosed for improving the efficiency with which data units are handled within a device, such as a networking device. Received data units, or portions thereof, are temporarily stored within one or more memories of a merging component, while the merging component waits to receive control information for the data units. Once received, the merging component merges the control information with the associated data units. The merging component dispatches the merged data units, or portions thereof, to an interconnect component, which forwards the merged data units to destinations indicated by the control information. The device is configured to intelligently schedule the dispatching of merged data units to the interconnect component. To this end, the device includes a scheduler configured to select which merged data units to dispatch at which times based on a variety of factors described herein.
