Abstract: In a code division multiple access (CDMA) communications system including one or more terminals (such as customer premise equipments, CPEs) that communicate with a node (such as an Internet gateway) via at least a random access channel and a reservation-oriented channel, various schemes of managing communications traffic among the channels are provided. Decisions as to the channel on which a given terminal may transmit may be based on: traffic statistics (such as packet size or average data rate over a time period), traffic content (such as packet type), the terminal's output buffer loading (queue state, or “Q-state”), a history of the terminal's output buffer loading (one or more Q-states), and so forth. In one application, decisions in managing traffic in a live user's web browsing sessions may involve intelligent ascertainment of whether a given terminal is busy based on traffic analysis or output buffer loading.

Abstract: One implementation provides a novel station-to-station handoff using an adaptive or directional antenna. The directional antenna generates a plurality of directional search beams to search for pilot signals from new base stations. The search beams are scanned one beam at a time to obtain the relative direction of all new base stations detected. From the detected base stations, a new base station with the strongest signal strength is selected and compared to the currently used base station. If the new base station has stronger signal strength than the current base station, then a communication handoff from the current base station to the new base station is initiated. In one feature of the present invention, two directional beams are used to communicate with the current and new base stations. Once a communication link is established with the new base station, the directional beam to the current base station is terminated.

Abstract: A method and an apparatus for quick retransmission of signals in a communication system are disclosed. A transmitting terminal, e.g., a base station, transmits signals in a form of packets to a receiving terminal, e.g., a subscriber station. The receiving terminal determines if the packet was intended for the receiving terminal, and if so, the receiving terminal demodulates the packet. The receiving terminal then computes a quality metric of the packet, and compares the computed quality metric with a quality metric contained in the packet. If the quality metrics match, the packet is declared correctly received, and is forwarded for further processing. If the quality metrics fail to match, the receiving terminal sends a request for retransmission of the packet. The transmitting terminal determines which packet needs to be retransmitted based on the request for retransmission. The transmitting terminal then schedules the packet for retransmission.

Abstract: At least one aspect of the invention provides a turbo encoder having parallel first and second constituent encoders and an interleaver coupled as an input to the second constituent encoder to provide a permutated version of the binary data input to the first constituent encoder to achieve a low frame error rate. The interleaver is configured to parse the binary data input into an input block, determine a permutation vector, and rearrange the order of the binary data in the input block according to a set of predetermined permutation equations. The rearranged binary data in the information block is then passed to the second constituent encoder to improve the distance spectrum of the transmitted redundant data.

Abstract: In a CDMA data communication system capable of variable rate transmission, utilization of beam switching techniques decreases the average interference caused by transmissions of a base station to subscriber stations within a cell, and in neighboring cells. Base stations utilize multiple transmit antennas, each transmitting signals at controlled amplitudes and phases, to form transmit signal corresponding to sector divisions. Data and reference signals are transmitted along sector division beams that alternate according to fixed time slots in order to increase system capacity and data rates by maximizing carrier-to-interference ratios (C/I) measured at subscriber stations.
