摘要： A two-way relay wireless communication method and device may combine multiple bit steams, for one source node and two target nodes, and broadcasting a network coded combined bit sequence to reduce the number of time slots for transmission. A first device may receive a signal from the source node and a target node simultaneously in a time slot. The first device may receive subsequent signals from the source node and multiple target nodes simultaneously in successive time slots. Hierarchical modulation may be applied to the received signals. The first device may decode the received signals and generate a plurality of intermediate bit sequences (IBS)s for a broadcast transmission. The generated IBSs may be grouped according to a channel condition. A second device may be configured to receive the broadcast transmission and decode a portion of the broadcast transmission that is intended for the second device.

摘要： A wireless communication apparatus (200) which uses fast Fourier transforms (FFTs) in an orthogonal frequency division multiplexing (OFDM) receiver (250) which incorporates a beam space antenna array (205). The beam space antenna array may be implemented with a Butler matrix array. The beam space antenna array may be a circular array, vertical array, or a combination of both circular and vertical arrays, for providing the desired angular antenna coverage. In one embodiment, the antenna array is optimized because the FFTs are linear invariant transform operators (210), whereby the order of operations in the OFDM receiver can be interchanged.

摘要： An adaptive equalizer including an equalizer filter and a tap coefficients generator used to process a sample data stream derived from a plurality of received signals is disclosed. The tap coefficients generator includes an equalizer tap update unit, a vector norm square estimator, an active taps mask generator, a switch and a pilot amplitude reference unit used to minimize the dynamic range of the equalizer filter. A dynamic mask vector is used to mask active taps generated by the equalizer tap update unit when an unmasked signal output by the equalizer filter is selected by the switch to generate an error signal fed to the equalizer tap update unit. A fixed mask vector is used to mask active taps generated by the equalizer tap update unit when a masked signal output by the equalizer filter is used to generate the error signal.

摘要： A method and apparatus for compensating for phase noise of symbols spread with a long spreading code are disclosed. To compensate for the phase noise, a phase error estimate is generated from despread symbols with a short spreading code. A phase correcting phasor is applied to chip rate data before despreading the data with a long spreading code. A signal-to-interference ratio (SIR) on a common pilot channel (CPICH) may be calculated by spreading the data with a parent spreading code in an orthogonal variable spreading factor (OVSF) code tree and by combining symbols. Alternatively, a magnitude of the symbols may be used in estimating the SIR. The SIR of a channel using a short spreading code and an SIR of a channel using a long spreading code are measured. The SIR of the channel with the long spreading code may be compensated in accordance with a difference between degradation of the SIRs.

摘要： A method and apparatus are described for minimizing inter-cell interference at multiple wireless transmit/receive units (WTRUs) using a shared node (SN). Each WTRU may be configured to receive a desired signal transmitted by a base station in a cell combined with interfering signals transmitted by other base stations in other cells in a first transmission time interval (TTI), and a precoded signal transmitted by the SN in a second TTI. The WTRUs may buffer the desired and interfering mixed signals received in the first TTI, and then combine the buffered signals with the precoded signal received in the second TTI to minimize the interfering signal's power and maximize the desired signal's power at each WTRU so that the desired signal may be decoded with higher probability. The SN may generate the precoded signal based on codewords or codeword components transmitted by the base stations in the same resource blocks.
