  • Patent number: 11159988
    Abstract: A graph of devices is constructed, each device requiring an amount of bandwidth over the network, each vertex of the graph corresponding to a respective one of the devices, each edge of the graph connecting devices according to a weight denoting interference between the connected devices. The vertices of the graph are labeled with labels such that no two vertices sharing the same edge have the same label, each label requiring bandwidth corresponding to the device of that label requiring the most bandwidth. If the sum of the bandwidth required for the labels exceeds the set bandwidth, the edge of the graph having the least interference is deleted, and the perform the construct and label operations are repeated. If the sum of the bandwidth required for the labels is within the set bandwidth, the bandwidth is assigned to the devices.

  • Patent number: 10123200
    Abstract: In some embodiments, one or more wireless stations operate according to Neighbor Awareness Networking (NAN)—direct communication with neighboring wireless stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. In a NAN system, multiple NAN devices may operate in conjunction in the form of a NAN cluster to facilitate communications processes, and may be further organized into “NAN data clusters” within NAN clusters. NAN data clusters may use a common base channel to convey communications among member NAN devices. Embodiments herein provide mechanism by which a base channel may be determined, modified, and/or distributed among NAN devices operating in a NAN data cluster.

  • Patent number: 10121210
    Abstract: During operation, an electronic device monitors data associated with different power states received from another electronic device via an interface circuit. Using the monitored data, the electronic device calculates a time duration that the other electronic device is in an active operating mode. Moreover, the electronic device determines power states of the other electronic device based on the calculated time duration and/or a time duration between times when data is received. Next, the electronic device calculates the power-consumption history of the other electronic device based on the determined power states and at least a model of power consumption in different power states of the other electronic device. By calculating the power-consumption history of the other electronic device, the electronic device may significantly improve the accuracy of a power-usage model for the other electronic device.

  • Patent number: 10111144
    Abstract: A communication system is disclosed comprising a first base station operating a first cell and a second base station operating a second cell. The first base station determines that load should be offloaded from the first cell towards the second cell based on a comparison of respective measurement result of a first type obtained for the first and second cells. The first base station controls load balancing based on a second comparison of respective measurement result of a second type for each of the first and second cells, wherein a second condition, when met, indicates that the base station operating the second cell will not offload load to the first cell based on the respective measurement result of the second type for the first and second cells.

  • Patent number: 10110353
    Abstract: Various methods and systems are provided for allocating time-frequency resources for downlink (DL) and uplink (UL) communications between base stations and mobile stations. Different forms of resource allocation messages including combinations of bitmaps and bitfields provide additional information about the resources and/or how they are assigned. In some implementations the resource allocation messages enable reduced overhead, which may ultimately improve transmission rates and/or the quality of transmissions.

  • Patent number: 10064093
    Abstract: Embodiments of the present invention provide a method and an apparatus for transmitting broadcast-multicast single-frequency network measurement data, where second measurement data is acquired by preprocessing acquired first measurement data, and the second measurement data is sent to a base station. Because the second measurement data is obtained after the first measurement data is preprocessed, a size of the second measurement data is smaller than that of the first measurement data, thereby reducing a transmission overhead.

  • Patent number: 9979464
    Abstract: An apparatus and method for combining transponder bandwidths comprises a wide-band virtual transponder for transmitting a single data stream. The wide-band virtual transponder is comprised of a plurality of narrow-band physical transponders. A plurality of elementary streams are statistically multiplexed to create the single data stream, wherein the single data stream is forward error correction encoded and demultiplexed into a plurality of transponder streams for transmission by the plurality of physical transponders. The physical transponders each use a different portion of a signal spectrum, wherein the different portion may be guard bands or a combination of legacy bands and guard bands. Upon receipt, the transponder streams are multiplexed to recover the single data stream, wherein the recovered single data stream is forward error correction decoded and statistically demultiplexed to recover the plurality of elementary streams.
