摘要： Embodiments are described herein to provide improvements to known network interference cancellation techniques. One general approach involves a receiver attempting to decode (801) a received signal which includes signaling from a wireless device transmission and at least one interfering transmission. If the receiver is unsuccessful in attempting to decode the received signal, decoded signaling that corresponds to the interfering transmission is requested (802). The receiver then uses the decoded signaling to decode (803) the received signal.

摘要： The present invention provides a method for obtaining and reporting performance information on node-to-node data transfers, i.e., network hops, based on integrated capabilities in Internet Protocol version 6 (IPv6), specifically extension headers. The performance of a (real-time) data flow is monitored between a source-destination pair by inserting specific information in an extension header of select data packets in the data flow. By initiating an extension header at a source client, and updating the extension header at any intermediate nodes along the source-destination path, a destination node can produce a detailed set of statistics relating to the current performance level of select nodes in a network based upon the reported data in the extension header. Additionally, data flow performance can be monitored on any desired network path or segment independent of particular flows on those paths.

摘要： A method and apparatus to quickly adjust a targeted Eb/N0 in a wireless communication system by using an effective Eb/N0 for each frame. The Eb/N0 distribution of a frame produces a certain frame error rate. Effective Eb/N0 is the Eb/N0 that would produce the same frame error rate in a model channel, such as an additive white Gaussian noise (AWGN) channel. The effective Eb/N0 for each frame is obtained and compared to a model targeted Eb/N0. The Eb/N0 for all of the power control groups in one frame compose the vector Eb/N0. The effective Eb/N0 for the frame is obtained by mapping a vector Eb/N0 into a scalar. The model targeted Eb/N0 is the Eb/N0 value that produces a desired frame error rate in the model channel. The targeted Eb/N0 is increased by one up step size when the effective Eb/N0 is smaller than the model targeted Eb/N0 and is decreased by one down step size when the effective Eb/N0 is larger than the model targeted Eb/N0. Eb/N0 are measured for each power control group in a frame. The wireless communication system includes a transmitter to transmit a signal, a receiver to receive the signal, and an outer control loop to adjust the targeted Eb/N0 based on a comparison of the effective Eb/N0 of the signal to the model targeted Eb/N0. Preferably, the outer control loop is implemented in software, although it can be implemented in hardware. Obtaining an effective Eb/N0 for each time period allows quicker adjustments of the targeted Eb/N0. This permits the targeted Eb/N0 to be closer to an Eb/N0 that produces a desired frame error rate, especially if the mobile is moving. This allows the transmitted power to be closer to the power needed to produce the desired frame error rate, permitting an increase in the capacity of the wireless communication system while still maintaining an acceptable number of errors.

摘要： In a cellular system based on industry standard IS-95 CDMA (code division multiple access), a symbol error count based reverse link outer loop power control technique uses non-adaptive SER targets. In particular, a base station set a fixed target for a 2nd order statistic, e.g., standard deviation (variance), of the symbol error count as a function of a target frame error rate (FER). The base station monitors a symbol error count of a received signal (transmitted from a mobile station). This symbol error count is used to update an estimate of the standard deviation of the symbol error count. This estimate of the standard deviation of the symbol error count is compared with a target standard deviation of the symbol error count to make changes in the EbT/N0T target. The adjusted EbT/N0T target is used to provide power control.

摘要： Methods for proxy-driven content rate selection for streaming media servers are provided. In one method, one or more maximum transmission rate parameters from a network controller are stored at a proxy server in response to a receiver report message from the client. A target rate for the media session is generated based on the stored maximum transmission rate parameters, and the target rate is transmitted to a media server in a proxy-to-server feedback message. The media server selects the content rate from among a plurality of supported content rates in response to the proxy-to-server feedback message from the proxy server, and streams streaming multimedia frames to the client at the selected content rate.

摘要： A method for efficient propagation of link state advertisements in densely interconnected OSPF networks is disclosed for reducing the number of duplicate LSAs propagated during a flooding event. The efficient propagation method includes calculating an LSA propagation subgraph which is used by a node which receives an LSA to determine which links to propagate the LSA upon. This allows a significant reduction in the LSAs which traverse the network during a flooding event. The reduction in LSAs is particularly useful for reducing network convergence times associated with flooding events. In addition, a system is disclosed for performing the method in both a centralized and dispersed manner.
