  • Patent number: 9780860
    Abstract: Systems and methods are described for controlling a reference signal mode to facilitate beamforming. A load amount for reference signals from one or more wireless devices in communication with an access node is determined and compared with load level criteria. When the load amount meets or exceeds the load level criteria, the one or more wireless devices are directed to transmit reference signals using a subband mode of transmission. A subband quality is determined for a plurality of subbands available for the one or more wireless devices and a subband for reference signal transmission is selected from the plurality of subbands based on channel quality criteria. Wireless transmission, such as from an access node, to the one or more wireless devices is scheduled utilizing beamforming based on the reference signal.

  • Patent number: 9766681
    Abstract: A method is provided for each router to individually manage retransmissions at run time in a single chip computer die or a single computer that includes cores or compute nodes and routers that interconnect the cores or the compute nodes. Each router compares static energy saving and dynamic energy increase from turning off a retransmission buffer of the router in a monitoring phase. When the static energy saving is greater than the dynamic energy increase, the router turns off the retransmission buffer in a subsequent monitoring phase. When the static energy saving is less than the dynamic energy increase, the router turns on the retransmission buffer in the subsequent monitoring phase.

  • Patent number: 9763192
    Abstract: Systems and methods are described for adjusting a sleep schedule of a wireless device in a wireless network. A mobility of a wireless device may be determined to exceed a threshold mobility. The wireless device may be operating in a sleep mode with a discontinuous reception schedule having listening intervals separated by sleep periods. A source access node may request to handover the wireless device to a target access node and may provide information to the target access node regarding the determined mobility and the determined sleep mode before handover completion. The target access node may then initiate wireless communication with the wireless device during a listening interval previously scheduled by the source access node. After the initial communication with the target access node, the wireless device may resume the previously determined sleep mode in order to optimize power use of the wireless device.

  • Patent number: 9743397
    Abstract: Systems and methods are disclosed for graph-based distributed parameter coordination in a communications network. In general, discrete local parameters to be coordinated among communication nodes in the communications network and their respective performance metrics, or costs, are modeled using a factor graph. Based on the factor graph, a variant of a sum-product algorithm, namely the min-sum algorithm, is applied in order for the communication nodes, through iterative message passing of reduced size messages with their neighboring communication nodes, to decide upon optimal values for the local parameters for the communication nodes that collectively optimize a global performance metric across the communications network. In one embodiment, the communications network is a wireless communications network. In one specific embodiment, the wireless communications network is a cellular communications network.

  • Patent number: 9742701
    Abstract: An apparatus for operating a low data-rate (LDR) link and legacy switch at a high data-rate (HDR) includes a first block and a second block. The first block receives input signals from the legacy switch and generates identical output signals. The second block receives the identical output signals and generates an HDR signal for communication over the LDR link coupled to an access point. Further, a media access control (MAC) interface communicates data at a first data rate with an Ethernet PHY block including a first-in-first-out (FIFO) module and a buffer. The FIFO receives data from the MAC interface at the first data rate and transmits data at a second data rate. The buffer receives data from the Ethernet port at the second data rate and transmits the received data at the first data rate in response to detection of an end of packet.
