    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: The present invention relates to methods and apparatus for preventing power imbalance in a multiple input multiple output (MIMO) wireless precoding system. According to one aspect of the present invention, a codebook is constructed with a first subset of codewords that are constant modulus matrices, and a second subset of codewords that are non-constant modulus matrices. A mapping scheme is established between the first subset of codewords and the second subset of codewords. When a unit of user equipment feeds back a first codeword that is a non-constant modulus matrix, the Node-B may replace the first codewords with a second codeword that is selected from the first subset of codewords and that corresponds to the first codeword in accordance with the mapping scheme.
