    摘要: A multi-user, multiple input, multiple output network and process for transmitting data in a communication system encompassing multiple users, contemplates the steps of: a first user transmitting a first transmission frame to a base transceiver station while a second user simultaneously transmits a third transmission frame to the base station; the first and second users simultaneously transmit a second transmission frame and a fourth transmission frames respectively to the base station, with the second transmission frame being an orthogonally spread version of the first transmission frame, and the fourth transmission frame being an orthogonally spread version of the second transmission frame.

    摘要: A method for performing a soft handoff for a mobile station from a source base station to a target base station in an Orthogonal Frequency-Division Multiple Access (OFDMA) wireless network that is capable of communicating with a plurality of mobile stations in a coverage area of the OFDMA wireless network is provided. The method includes determining whether a relative delay between receipt of a source pilot signal from a source base station and receipt of a target pilot signal from a target base station is less than a downlink coherence time. When the relative delay is less than the downlink coherence time, the soft handoff is performed.

    摘要: A base station for use in an OFDM network capable of communicating with a plurality of subscriber stations in a coverage area of the OFDM network. The base station transmits to a first subscriber station in a first subband of subcarriers from a first transmit antenna and transmits to the first subscriber station in a second subband of subcarriers from a second transmit antenna. The first and second subbands comprise different subcarriers. The base station also transmits to a second subscriber station in the first subband of subcarriers from the second transmit antenna and transmits to the second subscriber station in the second subband of subcarriers from the first transmit antenna.
