    摘要: Beam-formed transmission from a transmitting wireless communication station to a receiving wireless communication station is supported by estimating a direction for the beamformed transmission. The receiving station reports to the transmitting station information about wide-beam and narrow-beam pilot signals that the receiving station has received from the transmitting station. The transmitting station estimates the direction of the beamformed transmission based on this information.

    摘要: A base station for communicating with mobile stations in a coverage area of a wireless network. The base station comprises a first transmit antenna, a second transmit antenna, and an RF transceiver for generating an outgoing RF signal to be transmitted via the first and second transmit antennas to the mobile stations. The base station also comprises a switch coupling the RF transceiver to the first and second transmit antennas. The switch alternately directs the outgoing RF signal to the first transmit antenna during a first portion of a forward channel data frame and directs the outgoing RF signal to the second transmit antenna during a remaining portion of the forward channel data frame.

    摘要: A wireless network base station capable of canceling interference caused by a dominant interferer signal from a mobile station. The base station comprises down-converts an RF to a down-converted signal, r(n). K complex PN demodulators multiply the down-converted complex r(n) signal by PN code sequences associated with each of the K mobile stations to produce K chip streams. K Walsh code demodulators multiply each of the K chip streams by a Walsh code associated with a mobile stations to produce K raw user signals. K subtractors subtract a first estimated interference signal associated with the dominant interferer signal from the K raw user signals to produce K estimated user signals. A detector receives the K estimated user signals and produces a detected user signal for each of the mobile stations. An interference estimator then determines which detected user signal is the dominant interferer signal.

    摘要: A base station for communicating with mobile stations in a coverage area of a wireless network. The base station adapts a coding rate of user data being transmitted to a first mobile station in a forward channel (e.g. a Supplemental Channel) in order to maximize the number of Walsh codes available for use in the base station. The base station adapts the coding rate by increasing the coding rate and then transmitting the user data at the increased coding rate using a longer Walsh code. The longer Walsh code and the increased coding rate are selected in order to meet a target data rate.

    摘要: For use in a wireless network, a base station that reduces the call set-up time for a time-sensitive application. The base station comprises a message controller for receiving an incoming control message that initiates the time-sensitive application in a mobile station. In lieu of a conventional page message, the message controller transmits a short data burst message to the mobile station to initiate the time-sensitive application. The short data burst message is transmitted in a forward control channel. The mobile station completes the set-up by transmitting back an L2 Acknowledgment message in lieu of a conventional page response message.
