Abstract: A clustered computer system includes multiple computer systems (or nodes) on a network that can become members of a group to work on a particular task. Each node includes group state data that represents the status of all members of the group. A group state data update mechanism in each node updates the group state data at acknowledge (ACK) rounds, so that all the group state data in all nodes are synchronized and identical if all members respond properly during the ACK round. Each node also includes a main thread and one or more work threads. The main thread receives messages from other computer systems in the group, and routes messages intended for the work thread to either a response queue or a work queue in the work thread, depending on the type of the message. If the message is a response to a currently-executing task, the message is placed in the response queue. Otherwise, the message is placed in the work queue for processing at a later time.

Abstract: Logic circuitry (409) constantly monitors a transmitter (410) to determine if the transmitter (410) is idle. Logic circuitry (409) suppresses all NAKs until data and other channel information is not being transmitted by the transmitter (410) and RF resources are not scarce. Additionally, logic circuitry (409) suppresses all NAKs until a predetermined number of NAKs has been buffered by the logic circuitry (409). More particularly, logic circuitry (409) determines when a number of NAKs will sufficiently fill an over-the-air frame. Once the predetermined number of NAKs has been collected, the logic circuitry (409) will generate the appropriate NAKs.

Abstract: An idle frame counter is not reset after retransmission of a data frame. Additionally, if a non-acknowledgment (NAK) is received for the last data frame sent, then no more idle frames are transmitted. Finally, an Idle Acknowledgment (ACK) is transmitted when an idle frame has been received with a sequence number equal to the sequence number of the next new data frame expected.

Abstract translation: 重发数据帧后，空闲帧计数器不复位。 另外，如果对于发送的最后数据帧接收到未确认（NAK），则不再发送空闲帧。 最后，当接收到具有等于下一个新数据帧的序列号的序列号的空闲帧时，发送空闲确认（ACK）。

Abstract: ARQ is implemented in a fixed wireless communication system utilizing a demand access MAC, such as DOCSIS, and variable length PDUs, such as Ethernet packets, in messages between a base station and CPE. The base station inserts a sequence number into each PDU. The sequence numbers are members of a series, adjacent ones differing by the same factor. The CPE determines if any sequence number/s is/are missing from the packets of a received message, indicating a failure to receive their associated packets. The missing sequence numbers are included in a message back to the base station, which uses them to re-send the missing packets. The series may be generated according to a rule or algorithm available to both the base station and the CPE.

Abstract: In a data communication system capable of variable rate transmission, high rate packet data transmission improves utilization of the forward link and decreases the transmission delay. Data transmission on the forward link is time multiplexed and the base station transmits at the highest data rate supported by the forward link at each time slot to one mobile station. The data rate is determined by the largest C/I measurement of the forward link signals as measured at the mobile station. Upon determination of a data packet received in error, the mobile station transmits a NACK message back to the base station. The NACK message results in retransmission of the data packet received in error. The data packets can be transmitted out of sequence by the use of sequence number to identify each data unit within the data packets.

Abstract: Apparatus, and an associated method, for providing a radio link layer control procedure to maintain the sensitivity of UDP-Lite-formatted data at an RLP (Radio Link Protocol), or other, layer. An indicator generator generates an indication of the sensitivity-type of data that is formatted at the RLP layer. An RLP packet is generated, including the sensitivity data indicator value, and sent to a receiving station. When received thereat, the value of the sensitivity data indicator is utilized and subsequent actions, whether to permit retransmission of the data in the event of erroneous-, or non-, delivery is made.

Abstract: Hybrid ARQ techniques for error handling are described. The amount of redundancy transmitted in response to a first NACK message associated with a first attempt to decode a data block is variable. The number of redundancy units transmitted (and/or requested) can be selected based on various criteria including, for example, estimated channel quality, estimated block quality, memory usage, a number of outstanding blocks, etc.

Abstract: An object of the present invention is to improve the transmission efficiency and reduce circuit size in error compensating techniques where bit errors occurring during transmission are compensated for by retransmission.Transmission equipment get sequence number(s) from control information and sequence numbers which follows from the sequence number which correspond to newest data packet amongst the sequence numbers, and transmits data packet corresponding to these sequence numbers at a predetermined timing. On the other hand, reception equipment receives data packet from the transmission equipment, and manages the sequence numbers of not yet received data packets. The reception equipment then sends back sequence number(s) of predetermined number, which is smaller number than the maximum number of data packets which is sent from transmission equipment at a predetermined timing, which correspond to not yet received data packet as control information for each predetermined timing.

Abstract: A communication system dispatches packet data (130) from a master transceiver (10) to a slave transceiver (20). A slave transceiver (20) records the successful arrival of the data packet (130) in an acknowledgment history (115). When propagation conditions between a slave transceiver (20) and a master transceiver (10) are non-ideal, an acknowledgment (140) may be lost and needless retransmission of data packet (130) commenced. However, a slave transceiver (20) generates an acknowledgment (140) from an acknowledgment history (115) containing confirmations for multiple data packets contained within an outstanding packet window (120). If a specific acknowledgment (140) does not arrive at a master transceiver (10), a subsequent acknowledgment (140) contains confirmation of a previously received data packet (130) thus avoiding the needless retransmission of a previously successfully received data packet (130).

Abstract: Methods, systems, and devices for wireless communication are described. One method for wireless communication at a first device includes receiving a multicast packet from a second device, decoding control header information in the received multicast packet, determining that a decoding procedure associated with a payload of the received multicast packet is unsuccessful and transmitting a negative acknowledgement (NACK) based at least in part on the determining. The method also includes retrieving a list of transmitter identifiers. In some cases, transmitting the NACK is based at least in part on the list of transmitter identifiers. The method further includes determining a transmitter identifier associated with the multicast packet and determining that the transmitter identifier is present in the list of transmitter identifiers.
