    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 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.

    摘要: A base station for use in a wireless network communicating with a plurality of subscriber stations. The base station transmits in a downlink channel to a first subscriber station using a plurality of transmit antennas. The base station transmits to the first subscriber station using either a transmit diversity scheme or a beamforming scheme according to the amount of correlation between the transmit antennas observed at the first subscriber station. The base station also transmits to the first subscriber station using a cyclic delay diversity scheme having either zero delay or non-zero delay according to the amount of antenna/channel correlation observed at the first subscriber station.
