摘要： In a communications system implementing Transmission Control Protocol/Internet Protocol (TCP/IP), an apparatus and method for increasing the number of NAKs transmitted by a receiving device when an RLP error is detected in cases where the link speed into the RLP receiver is high, when the TCP window of the sender approaches the maximum or when the percentage of NAKs for which retransmissions cannot be fulfilled approaches a threshold. In a second aspect of the invention, the apparatus and method increases the number of retransmissions transmitted by a sending device when an RLP NAK is received in cases where the link speed out of the RLP sender is high and the transmission round is the first, when the TCP window of the sender approaches the maximum or when the percentage of NAKs for which retransmissions cannot be fulfilled approaches a threshold.

摘要： An apparatus and method for determining (410) a quality of channel factor for a base transceiver station (530) of an active set and determining (420) whether the base transceiver station (530) should be assigned to a prefill set at least in part according to a predetermined function of the factor. The predetermined function may include assigning (425) a base transceiver station (530) to the prefill set when the quality of channel factor reaches a predetermined threshold. The quality of channel factor may be determined in various ways including executing (416) an anticipative signal strength algorithm or by monitoring (412) the quality of channel between the mobile station (110) and the base transceiver station (530). Additionally, the primary base transceiver station (120) may be notified (430) of the prefill set such that synchronization signals may be sent (440) to the base transceiver stations of the prefill set.

摘要： A node within a communication system periodically broadcasts its interference status to neighboring nodes within the communication system. Additionally, the node receives an interference status from all neighboring nodes. If communication is desired with a neighboring node, the node accesses the stored table for the particular neighboring node and determines an optimal time for transmission to the neighboring node. This is accomplished by utilizing the table received from the neighboring node and determining the neighboring node's optimal times for reception.

摘要： An apparatus and method for monitoring (310) at least one factor relating to a wireless communication system (100) is provided such that a synchronization signal is sent (320) to at least one base transceiver station (130) neighboring a primary base transceiver station (120) at least in part according to a predetermined function of the monitored factor(s). The monitored factor may be any of several factors that weigh on the operation of the wireless communication system. The synchronization signal itself may vary in how it signals to the neighboring base transceiver station(s) (130) to synchronize with the data to be sent to a given mobile station (110) from its primary base transceiver station (120), and the number of synchronization signals sent over a given time may vary according to the predetermined function of the monitored factor(s).

摘要： A self synchronizing network protocol which allows networks to become self synchronizing. Two pairs of nodes communicate in an ad hoc packet radio network. Packets are communicated over a plurality of frames of time. A known bit field is appended to each packet. A clock at the first pair of nodes (10 and 12) is unavoidably slower than the clock at the second pair of nodes (14 and 16). As a result, packets transmitted from the second pair of nodes (14 and 16) will eventually overlap packets transmitted from the first pair of nodes (10 and 12). Errors in the appended field (17) can be used to detect such an overlap in advance to prevent damage to the payload. The protocol provides for additional channel efficiency, more responsiveness and the ability to grow without a central controller. Further, the ability to accommodate new traffic is increased.

摘要： A base station has a transmission element to wirelessly transmit at least one data frame. The at least one data frame has a predetermined uplink allocation and a predetermined downlink allocation. A detection element detects a congestion condition. When the congestion condition is detected, the transmission element transmits a request to at least one neighboring base station for an expansion of the predetermined uplink allocation or the predetermined downlink allocation. A reception element receives a signal from the at least one neighboring base station. A processing element expand the one of the predetermined uplink allocation or the predetermined downlink allocation by a specified amount in response to the signal indicating the specified amount for a mutually agreed time, or number of symbols or frames.

摘要： A method and a system for scheduling requests generated for a plurality of mobile devices in a communication network (100) has been disclosed. The requests are generated for a transmission opportunity. The method includes computing a sort metric (302) for each request, based on an information update. A lead-time is then computed (304) with respect to a drop-dead time for each request, based on the sort metric for a time slice. The drop-dead time for a given time slice is the time before which scheduling has to be done so that data can be transmitted during the given time slice. Each request may be considered (306) for allocation in the time slice before the beginning of a next time slice, based on the lead-time.

摘要： A joint assembly for connecting two spaced drive shafts, such as in a submergible pumping system. The joint assembly comprises a connecting shaft having enlarged bodies on each end thereof, a housing surrounding each enlarged body, each housing connectable to one of the drive shafts, lock devices for preventing relative rotational movement of the connecting shaft with respect to the drive shafts, and mechanisms within each housing acting upon the enlarged bodies to bias the connecting shaft into coaxial alignment with the drive shafts. With this joint assembly lateral displacement or "wobble" of the drive shafts is permitted, yet the bias mechanisms tend to restore the drive shafts to coaxial alignment.
