  • Patent number: 10447608
    Abstract: System and method of data routing according to a hierarchical scheduling process. Incoming data traffic is allocated to various queues of a buffer. A scheduling tree has a top level for queues, a bottom level for egress ports, and a plurality of intermediate levels corresponding to different granularities with respect to service categories. Each queue is assigned to a particular node in each intermediate level of the scheduling tree. The scheduling tree traverses through multiple scheduling stages from the bottom to the top level to select a winner node in each level based on a variety of fairness and differentiating variables. A queue associated with the winner nodes in various levels is selected for outgoing transmission at the selected egress port. Priority information is dynamically propagated from upper nodes to lower nodes such that a subsequent scheduling process uses the updated priority information.

  • Patent number: 10433323
    Abstract: A communication control station device controls whether or not spatial sharing is applied between a first communication period and a second communication period. An operation determining section determines whether a first communication operation or a second communication operation out of communication operations is executed in each of the first communication period and the second communication period. The first communication operation requires lower transmission power than the second communication operation. A message generator generates messages requesting a first group of communication terminal devices communicating in the first communication period and a second group of communication terminal devices communicating in the second communication period to perform predetermined measurement in accordance with the determined communication operations.

    Abstract: Methods, systems, and devices for wireless communication are described. A base station supporting multimedia broadcast multicast service (MBMS) and operating in a shared radio frequency spectrum band may map MBMS transport blocks (TBs) to each carrier in the system bandwidth. The device may perform a clear channel assessment (CCA) on one or more of the carriers, and transmit a portion of the MBMS TBs on carriers with successful CCAs. The portion of the MBMS TBs mapped to carriers with unsuccessful CCAs may be punctured. In various examples, a single TB may be mapped across the carriers, different TBs may mapped to each carrier, or redundancy versions (RVs) may be mapped to each carrier. A region at the frequency boundary of each carrier may be reserved for a guard region, and may not be used for MBMS transmissions when a carrier is associated with a failed CCA.

  • Patent number: 10412201
    Abstract: Methods, systems, and devices for wireless communication are described. A base station may perform a clear channel assessment (CCA) procedure on a channel that includes multiple sub-bands of a radio frequency spectrum band. The base station may determine that the channel is available based on the CCA and transmit a special header in the channel. In some examples, the special header may include multiple transmission time intervals (TTIs), where each TTI may include a header packet in each sub-band of the radio frequency spectrum band. In some cases, the header packet may include a clear to send (CTS)-to-self frame structure. The base station may transmit a first TTI across each of the sub-bands at a first power level, and transmit additional TTIs across the sub-bands at a different power level. Additional header packets may be transmitted at the boundaries of subsequent subframes.

  • Patent number: 10411910
    Abstract: A ring network architecture includes multiple communication nodes configured in a ring. Wave pipelining is used to provide for high bandwidth and low latency on-chip communications. Each node implements a source-synchronized clocking scheme, such that there is no need to build an extensive low skew clock-tree across a large die area. A single reference clock signal is generated within a root node, and is routed through each of the nodes of the ring network in a unidirectional manner. Each node includes a timestamp counter and a color bit register, which store values that enable the node to resolve ordered transaction messages issued by the other nodes in a precise order, even though the nodes are operating independently, and receive the various transaction messages in totally different timing orders. Because the control logic is distributed among the nodes, no centralized controller is necessary.
