  • Link aggregation and dynamic distribution of network traffic in a switching clos network
    Patent number: 10530680
    Abstract: Systems and methods are described for link aggregation and dynamic distribution of network traffic in a switching Clos network. In one embodiment of the present invention, a spine switch of a Clos network learns a first mapping of a Media Access Control (MAC) address of a client device to a first port of the spine switch and a second mapping of the MAC of the client device to a second port of the spine switch. The spine switch aggregates the first mapping and the second mapping as a link group for the MAC address of the client device in a MAC address table and distributes network traffic destined for the MAC address of the client device among members of the link group.

  • Distributed multicast logical router
    Patent number: 10523455
    Abstract: For a managed network implementing at least one logical router having centralized and distributed components, some embodiments provide a method for processing multicast data messages at a first managed forwarding element (MFE) executing on a first host machine that implements a distributed multicast logical router and multiple logical switches logically connected to the logical router in conjunction with a set of additional MFEs executing on additional host machines. The method replicates multicast data messages received from a source data compute node (DCN), operating on the first host machine, that logically connects to a first logical switch of the multiple logical switches. The method replicates the multicast data message to a set of DCNs in the multicast group in the logical network without routing through a centralized local multicast router.

  • Integrated circuit for sequence reporting and sequence generation
    Patent number: 10517090
    Abstract: Disclosed are a sequence report method and a sequence report device for reducing a signaling amount for reporting a Zadoff-Chu sequence or a GCL sequence allocated for a cell. Indexes starting at 1 are correlated to different ZC sequences and are allocated for cells so that the indexes are continuous. When such ZC sequences are reported from BS to UE, a start index indicating the start of the continuous indexes is combined with the number of allocated sequences and they are reported as allocation sequence information by a report channel. The UE and the BS share the correlation between the ZC sequences and the indexes and the UE identifies a usable sequence number according to the correlation and the allocation sequence information reported from the BS.

    Patent number: 10516425
    Abstract: A system that incorporates the subject disclosure may include, for example, determining interference at a receiver of a wireless mobile device based on an updated indication of receiver performance at a receiver frequency. A wireless interference pattern is determined based on wireless emitters operating at a number of emitter frequencies. Distances are determined between the wireless mobile device and at least some of the wireless emitters, and an interference source is identified based on both of the wireless interference pattern and the distances. After determining the interference source, one of the emitter frequency, the receive frequency, or a combination thereof, is reassigned to a new frequency. The frequency reassignment is based on the interference pattern and separation distances and results in a modification to the interference pattern. Other embodiments are disclosed.

  • Apparatus and method for periodic channel state reporting in a wireless network
    Patent number: 10511428
    Abstract: Channel State Information (CSI) is reported by a subscriber station to a base station. The CSI is reported periodically for at least two physical uplink control channels (PUCCH). In case of a collision between a report for a first PUCCH and a report for the second PUCCH, each of the report types is partitioned into one of a number of classes, which include: a first class for rank indicator related report types and wideband (WB) W1 report types; a second class for WB report types or WB channel quality indicator report types; and a third class for subband related report types or W1 report types. A priority rule assigns a priority to each of the classes. The CSI feedback reports are transmitted according to the priority rule such that the report type included in a higher class is transmitted and the report type included in the lower class are dropped.

  • Service processing method and apparatus
    Patent number: 10506497
    Abstract: The present invention discloses a service processing method and apparatus, which belong to the field of Internet technologies. After the AP and an STA first perform MAC address change notification and then establish a first MAC connection, the AP sends service data of the STA to the STA through the first MAC connection by using a resource related to a second MAC connection. Therefore, in a MAC address change process, there is no need to re-establish a resource at an upper layer of a MAC layer, and only a change in invoking a MAC layer resource is required at a layer at which the MAC layer resource is used. Time and a resource for processing a service can be reduced without affecting service continuity and stability of the upper layer. Therefore, the service is processed in a timely manner and service processing efficiency is improved.

  • User equipment battery saving in a HetNet deployment with eICIC
    Patent number: 10506512
    Abstract: Devices and methods are provided for reducing client node power consumption when monitoring first and second channels corresponding to first and second access nodes in a heterogeneous wireless-enabled communications environment. Enhanced Inter-Cell Interference Coordination (eICIC) operations are performed to mitigate interference between a first access node and a second access node. The client node monitors first and second channels corresponding to the first and second access nodes to detect the presence of Almost Blank Subframes (ABS) pattern data transmitted on the first channel. When detected, the client node ceases monitoring the first channel to reduce power consumption and thereby conserve battery resources.
