  • Patent number: 10020860
    Abstract: User equipment (UE) is configured to receive two types of channel state information (CSI) reference signals (CSI-RS), the first containing more antenna ports and measured less often than the second. A first CSI report is based on first type CSI-RS and a second CSI report on the second type CSI-RS. The second type CSI-RS is at least partially precoded in response to the first CSI report, is precoded for the specific UE, and is transmitted more often than the first type CSI-RS, while the first type CSI-RS is not precoded. The first CSI report contains a first precoding matrix indicator (PMI) parameter and the second CSI report contains only a second PMI parameter of a two-PMI codebook, where the first PMI parameter is a long-term and wideband PMI. The first PMI is derived from measuring the first type CSI-RS in a plurality of subframes and resource blocks.

    Abstract: System, method, and apparatus for improving the performance of collective operations in High Performance Computing (HPC). Compute nodes in a networked HPC environment form collective groups to perform collective operations. A spanning tree is formed including the compute nodes and switches and links used to interconnect the compute nodes, wherein the spanning tree is configured such that there is only a single route between any pair of nodes in the tree. The compute nodes implement processes for performing the collective operations, which includes exchanging messages between processes executing on other compute nodes, wherein the messages contain indicia identifying collective operations they belong to. Each switch is configured to implement message forwarding operations for its portion of the spanning tree. Each of the nodes in the spanning tree implements a ratcheted cyclical state machine that is used for synchronizing collective operations, along with status messages that are exchanged between nodes.

  • Patent number: 9974062
    Abstract: A method whereby a user equipment (UE) transmits hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative ACK (NACK) information corresponding to downlink data received from a corresponding base station (ENB) in a long term evolution-advanced (LTE-A) system supporting carrier aggregation (CA) is provided. When physical uplink shared channel (PUSCH) transmission is not scheduled at the time of transmission of HARQ ACK/NACK information, the UE transmits HARQ ACK/NACK information via physical uplink control channel (PUCCH). When PUSCH transmission is scheduled, the UE transmits HARQ ACK/NACK information multiplexed with PUSCH to the ENB. The amount of HARQ ACK/NACK information increases in proportion to the number of aggregated carriers. The present disclosure specifies scheduling operation of the ENB and HARQ ACK/NACK mapping of the UE that maintain reception performance of HARQ ACK/NACK and PUSCH when HARQ ACK/NACK information is multiplexed with PUSCH.

The device may cause the input component to queue the packets. The device may selectively dequeue a packet from the input component, to be sent to an output component, based on whether the credit value for the output component satisfies a credit threshold. The device may send the packet to the output component based on a destination of the packet when the packet is dequeued from the input component. The device may determine a size of the packet after the packet is dequeued. The device may update the credit value for the output component based on the size of the packet. The device may output the packet to another network device via the output component.
