  • Patent number: 8243710
    Abstract: A method, apparatus and computer program product for the express forwarding are presented. A timer (NAV) is maintained at each respective node of a wireless LAN. A frame is designated as a TSQ frame to be express forwarded from a first node to a second node. A duration field of the frame is incremented by a first predetermined time increment (DT0) before the TSQ frame is forwarded and the TSQ frame is forwarded by the first node to the second node. A response is received from the second node wherein non-forwarding neighboring nodes each set their NAV according to a value equal to the duration field of the response. The second node attempts transmission of the TSQ frame when acknowledgement of receipt of the TSQ frame is complete.

    Abstract: A scheduler is adapted to schedule packets or other data blocks for transmission from a plurality of transmission elements in timeslots of a frame in a communication system. In scheduling for a given frame, the scheduler initially designates each of the transmission elements as eligible to transmit one or more data blocks in the given frame, and selects from among those of the transmission elements designated as eligible at least one of the transmission elements for scheduling in a next available timeslot of the given frame. The scheduler then adjusts the eligibility status of the selected transmission element(s), and repeats the selecting and adjusting operations for one or more remaining timeslots of the given frame.

  • Patent number: 8160075
    Abstract: Although described herein in terms of UE out-of-sync detection, those of skill in the art will readily recognize that embodiments of the present invention improve in-sync detection for currently out-of-sync UEs 22. That is, if an out-of-sync UE 22 detects sufficiently good channel conditions, it may announce this fact to the network and re-acquire in-sync status. For example, if the UE 22 receives F-DPCH signal transmissions and determines that, e.g., the TPC command error rate is less than a threshold, which is preferably much lower than 30%, over a measurement interval of, e.g., 240 slots (or 160 ms), the UE 22 may conclude that it is in-sync and announce this fact to the network 10. The restrictions of only valid F-DPCH transmissions during the UL DTX gated period will obviously enhance the reliability of this determination, just as is the case in determining out-of-sync status.

  • Patent number: 8144585
    Abstract: A method of receiving communications at a data processing device includes receiving a packet from a virtual channel associated with a physical communication link. The packet is associated with a link virtual channel, and is stored in a storage location with the link virtual channel. Multiple internal virtual channels can be associated with the link virtual channel. A pointer to the storage location is enqueued in one of a plurality of FIFOs associated with one of the internal virtual channels. Each FIFO of the plurality of FIFOs stores pointers associated with a different internal virtual channel, allowing receiver arbitration logic to reorder between internal virtual channels based on internal resource availability and current priorities among virtual channels. This reduces the likelihood of communication deadlock and supports multiple classes of service.

  • Patent number: 8085784
    Abstract: With time intervals and transmission times of packets of real time streams, transmission end times thereof are calculated. The transmission order of packets of the real time streams is decided in the order of the earlier transmission end times thereof. Transmission end times of packets of a non-real time stream are compared with the scheduling times of packets of the plurality of real time streams. When the transmission end times of packets of the non-real time stream are earlier than any one of the scheduling times of packets of the plurality of real time streams, the packets of the non-real time streams are transmitted.

  • Patent number: 8085744
    Abstract: A wireless communication network that forms an ad-hoc network without the arrangement of a controlling station sets a period that a communication apparatus can utilize with priority and performs isochronous communication in the period as required. When isochronous communication has not been performed or after isochronous communication has finished in the priority utilization period, other communication apparatuses perform arbitrary communication. When another communication is performed in a communication apparatus's own priority utilization period, the start of isochronous communication is temporarily delayed. In an ad-hoc communication environment, data having a real-time characteristic, such as AV content, can be efficiently transmitted through the isochronous communication.

  • Patent number: 8085786
    Abstract: Systems and methodologies are described that facilitate data throughput optimization in a receiver through prioritized decoding of data transmissions. In particular, mechanisms are provided that assign priorities to obtained packets and/or sub-packets of a data transmission. The priorities can be assigned based at least upon prioritization rules that identify packets and/or sub-packets most likely to successfully decode. The obtained packets and/or sub-packets are decoded based upon the assigned priorities.

  • Patent number: 8073014
    Abstract: During each node's awake period, each node multicasts the relative time or slot of their next awake period (beaconing interval) to all neighboring nodes. This enables each node to intelligently and independently schedule the time slot of its next transmission based on the beaconing intervals of the nodes it has heard from. During each active (awake) interval, a node builds statistics of the future transmission/receive times of its neighbors and uses them to determine its next transmission time. In one proposed implementation, at the end of an active interval, a node picks the time slot with the highest counter for its next transmission. In another proposed implementation, at the end of an active interval, a node picks one of the slots with a weighted probability; the weight of each slot is proportional with the value of the counter associated with the slot.

  • Patent number: 8068731
    Abstract: A dynamic bandwidth allocation method of an Ethernet passive optical network, comprises a predictor and a rule of QoS-promoted dynamic bandwidth allocation (PQ-DBA); the predictor predicts a client behavior and numbers of various kinds of packets by using a pipeline scheduling predictor consisted of a pipelined recurrent neural network (PRNN), and a learning rule of the extended recursive least squares (ERLS); the present invention establishes a better QoS traffic management for the OLT-allocated ONU bandwidth and client packets sent by priority.

  • Patent number: 8068497
    Abstract: A medium access control (MAC) architecture reduces transmission latency for data block retransmissions. A plurality of data blocks are received and temporarily stored in a first memory (e.g., queue, buffer). The plurality of data blocks are then transmitted. A determination is made as to whether each of the transmitted data blocks was received successfully or needs to be retransmitted because the data block was not received successfully. Each of the transmitted data blocks that needs to be retransmitted is marked and temporarily stored in a second memory having a higher priority than the first memory. The marked data blocks are retransmitted before data blocks stored in the first memory location.

  • Patent number: 8040898
    Abstract: A wireless LAN communications system with high transmission efficiency is provided. When a first wireless terminal normally receives a Data1 signal from an access point, the wireless terminal transmits an ACK signal. In the case where the wireless terminal has transmission data, the client transmits a Data2 signal to the access point after an SIFS interval. Meanwhile, when the access point or a second wireless terminal receives the ACK signal from the first wireless terminal, the second client waits a (DIFS+random number) interval, in accordance with the IEEE 802.11 standard. As a result, the first wireless terminal is able to transmit the Data2 signal with priority, without interference from signals from other devices.
