    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 and apparatus for transmission between a plurality of units of user equipment and a base station in a wireless communication system. For each of the units of user equipment, a plurality of control channel elements are mapped to a plurality of downlink acknowledgement channel resources in accordance with a first mapping scheme, and the plurality of control channel elements are mapped to a plurality of uplink acknowledgement channel resources in accordance with a second mapping scheme. The first mapping scheme and the second mapping scheme may be different for different units of user equipment. Alternatively, the first mapping scheme and the second mapping scheme may change over time.

    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.
