  • Patent number: 10270518
    Abstract: Methods and wireless devices are described. A method includes a wireless device transmitting to wireless transmit/receive units (WTRUs) by being scheduled by the base station or using a pool of radio resources, which is for any of a plurality of wireless devices to use for transmission to WTRUs. On a condition that the wireless device is to be scheduled by the base station, the wireless device receives scheduling information for transmission to a WTRU having a group radio network terminal identifier (RNTI) and transmits to the WTRU in response to the received scheduling information. The scheduling information for transmission to the base station uses a different RNTI. On a condition that the wireless device is to use the pool of radio resources for transmission to a WTRU, the wireless device transmits to the WTRU without being scheduled by the base station using the pool of radio resources.

  • Patent number: 10070385
    Abstract: A system of multiple concurrent receivers is described to process multiple narrow bandwidth wireless signals with arbitrary bandwidth and center frequency separation. These multiple receivers may provide a downconverted signal at the baseband frequency to process signal bandwidth using the lowest power consumption while using fully modular signal processing blocks operating at the low frequency. The concurrent receivers may operate from a single high frequency amplifier and may be derived from a low impedance point to reduce loading and improve scalability. The center frequency and bandwidth of each of the channels as well as phases of each of the channels may be independently reconfigured to achieve scalability, and on-chip test and calibration capability.

  • Patent number: 10063489
    Abstract: TCP data packets are transferred from a plurality of server nodes to a client node, wherein the proxy node captures all packets of the TCP flows, buffers the captured packets in a TCP stack and updates an active TCP flow list in a subscriber record representing the client node. A current proxy scheduling capacity from a current maximum amount of data allowed concurrently in transmission in one more TCP flows to the client node is estimated. When a triggering event is received, a packet retrieved from the TCP stack is scheduled in accordance with the estimated current proxy scheduling capacity and order given by the active flow list. The scheduled packet is transmitted and the active flow list is updated, whereupon scheduling a TCP flow for transmission is repeated until the current proxy scheduling capacity has been reached or there are no TCP flows in the active flow list.
