摘要： A UNMTS (universal mobile telecommunications system) based system comprises a common control point, a number of base stations, K, and a mobile terminal. During a soft handoff involving the K base stations and the mobile terminal, the common control point receives individual user channel transmit powers from each of the K base stations. In addition, the common control point receives two parameters from the mobile terminal—the identity of that base station involved in the soft handoff that has the strongest received signal at the mobile terminal and, on an average, a value representing how much stronger the received SNR was in comparison to the SNR target maintained by the mobile terminal. The common control point then decides on a downlink reference user channel transmit power for each of the base stations as a function of the individual user channel transmit powers reported by each base station involved in the soft handoff and the information provided from the mobile terminal.

摘要： A novel topology sensing methodology is provided for point-to-point link setup among a set of network nodes, which are mobile. The technique provided is TDMA contention-based, where each network node sends pilot signals to announce its existence. Pilot signals transmitted by network nodes are used by surrounding nodes to extract various pieces of information such as node identity, node location and potential link quality. Information collected from pilot signals of neighboring nodes is used in conjunction with other topological criteria to identify the best set of nodes with which a given node should establish links. The topology sensing methodology avoids duplexer problems and attempts to achieve minimum collision by allowing the nodes to continually monitor available pilots and transmit on the least-interference channels. The topology sensing methodology can also optionally make use of GPS information, when available, in order to provide an accurate map for communicating nodes and improve the link setup process.

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： Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. As this cable plant was deployed in a tree and branch topology, data transmissions may be susceptible to noise, variable transmission loss and frequency dispersion, particularly in the upstream direction. Further, due to the tree and branch topology, homes at the far end of the network experience much greater loss than do the homes that are near to the headend/ONU. The present system, which uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals, or messages, are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router. Messages indicative of an end user routing ID (RID) are identified and the information extracted for user with successive messages. In this manner, the data links are made over relatively short runs of coax cable, which can provide greater bandwidth than the typical end-to-end feeder/distribution connection between a home and the headend or optical network unit.
