    摘要： A plurality of data signals are received over an antenna array having a plurality of antenna elements. The data signals are transmitted over a shared spectrum in a wireless communication system. A signal having each of the data signals is received over each antenna element. The plurality of data signals are grouped into a plurality of groups. The received signals of the antenna elements are matched filtered for a first group of the plurality of groups, producing a matched filtered result. Data is jointly detected of the first group using the matched filtered result. An interference correction signal is constructed using the detected data for each antenna element. The interference cancelled result is subtracted from the received signal of each antenna element, producing an interference cancelled result for each antenna element. Data is successively detected for remaining groups using the interference cancelled result for each antenna element.

    摘要： A wireless communication method and apparatus for generating a scheduling grant based on a relative grant are disclosed. A wireless transmit/receive unit (WTRU) receives an absolute grant from a serving radio link set (RLS) and receives a relative grant from the serving RLS and at least one non-serving radio link (RL). The WTRU decodes enhanced dedicated channel (E-DCH) absolute grant channel (E-AGCH) signals to detect an absolute grant, and decodes E-DCH relative grant channel (E-RGCH) signals to detect at least one relative grant. The WTRU then calculates a serving grant based on the detected absolute grant and/or the relative grant(s). The relative grant may be detected by performing a hypothesis test on the E-RGCH signals. A multiple alternative hypothesis test is performed for detecting the E-RGCH signals from the serving RLS and a binary hypothesis test is performed for detecting the E-RGCH signals from the at least one non-serving RL.

    摘要： A transmitter site transmits a plurality of data signals over a shared spectrum in a code division multiple access communication system. Each transmitted data signal experiences a similar channel response. A combined signal of the transmitted data signals is received. The combined signal is sampled at a multiple of the chip rate. The channel response for the combined signal is determined. A first element of a spread data vector is determined using the combined signal samples and the estimated channel response. Using a factor from the first element determination, remaining elements of the spread data vector are determined. The data of the data signals is determined using the determined elements of the spread data vector.

    摘要： A method and apparatus for reducing the processing rate when performing chip-level equalization (CLE) in a code division multiple access (CDMA) receiver which includes an equalizer filter. Signals received by at least one antenna of the receiver are sampled at M times the chip rate. Each sample stream is split into M sample data streams at the chip rate. Multipath combining is preferably performed on each split sample data stream. The sample data streams are then combined into one combined sample data stream at the chip rate. The equalizer filter performs equalization on the combined sample stream at the chip rate. Filter coefficients are adjusted by adding a correction term to the filter coefficients utilized by the equalizer filter for a previous iteration.

    摘要： The present invention is related to a method and system for transmit power control in a multiple-input multiple-output (MIMO) wireless communication system. Both a transmitter and a receiver comprise multiple antennae for transmission and reception. The transmitter comprises a power allocation unit for controlling transmit power based on a feedback received from the receiver. The receiver comprises a channel estimator and a singular value decomposition (SVD) unit. The channel estimator generates a channel matrix from a signal received from the transmitter and the SVD unit decomposes the channel matrix into D, U and V matrices. The receiver sends a feedback generated based on output from the SVD unit to the transmitter for controlling the transmit power. The feedback may be one of an eigenvalue, a transmit power level or a power control bit or command. A hybrid scheme for selecting one of them based on channel condition may be implemented.

    摘要： A wireless transmit/receive unit (WTRU) is configure to receive and sample wireless signals in a shared spectrum where the wireless signal comprise encoded symbols. The WTRU has a channel estimation device configured to process received signal samples to produce an estimate of a channel response of the received signals corresponding to a matrix H. The channel estimation device is preferably configured to process the received signal samples to produce an estimate of noise variance of the received signals. The WTRU has a two stage data estimator that includes a channel equalizer and a despreader. The channel equalizer is configured to process received signal samples using the estimated channel response matrix H and the estimate of noise variance to produce a spread signal estimate of the received signals. The despreader is configured to process the spread signal estimate of the received signals produced by said channel equalizer to recover encoded symbols of the received signals.
