摘要： K data signals, or bursts, are transmitted over a shared spectrum in a code division multiple access communication format. A combined signal is received and sampled over the shared spectrum, as a plurality of received vector versions. The combined signal includes the K transmitted data signals. A plurality of system matrices and an associated covariance matrix using codes and estimated impulse responses of the K data signals is produced. Each system matrix corresponds to a received vector version. The system and covariance matrices are extended and approximated as block circulant matrices. A diagonal matrix of each of the; extended and approximated system and covariance matrices are determined by prime factor algorithm—fast Fourier transform (PFA-FFT) without division of the matrix. The received vector versions are extended. A product of the diagonal matrices and the extended received vector versions is taken. An inverse block discrete Fourier transform is performed by a PFA-FFT on a result of the product to produce the estimated data of the K data signals.

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.

In addition, the system provides easy and fast generation of the available code list without the help of look-up table. This capability improves the dynamic code assignment.

摘要： A method and apparatus for scheduling transmissions via an enhanced dedicated channel (E-DCH) are disclosed. A scheduled power is calculated for scheduled data flows. A remaining transmit power is calculated for the E-DCH transmission. A rate request message is generated, wherein the scheduled power, remaining transmit power and rate request message are used to select transport format combinations (TFCs) and multiplex data scheduled for the E-DCH transmission. The remaining transmit power is calculated by subtracting from a maximum allowed power the power of a dedicated physical data channel (DPDCH), a dedicated physical control channel (DPCCH), a high speed dedicated physical control channel (HS-DPCCH), an enhanced uplink dedicated physical control channel (E-DPCCH) and a power margin.

摘要： A wireless communication method and apparatus for decoding enhanced dedicated channel (E-DCH) absolute grant channel (E-AGCH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-AGCH data which includes a cyclic redundancy check (CRC) part and a data part. The CRC part is masked with a WTRU identity (ID) at a Node-B. The CRC part and the data part are demultiplexed and the CRC part is demasked with the WTRU ID. A CRC is then performed with the demasked CRC part. If the CRC passes the data part is sent to an enhanced uplink medium access control (MAC-e) entity. The WTRU ID may be a primary E-DCH radio network temporary identity (E-RNTI) or a secondary E-RNTI. When the E-AGCH data is transmitted over a 10 ms frame, if the CRC fails, E-AGCH data via subsequent subframe may be soft combined with the previous E-AGCH data.
摘要翻译：公开了一种用于解码增强专用信道（E-DCH）绝对授权信道（E-AGCH）传输的无线通信方法和装置。无线发射/接收单元（WTRU）接收包括循环冗余校验（CRC）部分和数据部分的E-AGCH数据。 CRC节点在Node-B处被掩码为WTRU身份（ID）。 CRC部分和数据部分被解复用，并且CRC部分被解除与WTRU ID。然后用解除的CRC部分执行CRC。如果CRC通过，则将数据部分发送到增强型上行链路媒体访问控制（MAC-e）实体。 WTRU ID可以是主E-DCH无线电网络临时标识（E-RNTI）或辅助E-RNTI。当通过10ms帧发送E-AGCH数据时，如果CRC失败，则经由后续子帧的E-AGCH数据可以与先前的E-AGCH数据进行软组合。

摘要： A method and system for uplink (UL) synchronization of an uplink transmission from a plurality of wireless transmit/receive units (WTRUs) to a Node-B in a code division multiple access (CDMA) system. A Node-B receives a transmission including a UL synchronization (SYNC_UL) sequence from a WTRU. A sampler samples the transmission at a sampling rate which is higher than a chip rate. The samples are down-sampled and the SYNC_UL sequence is detected at a lower rate. A first significant path location of the detected SYNC_UL sequence is determined, and based on the first significant path location, a final significant path location is determined. The final significant path location is quantized and UpPCHPOS is transmitted to the WTRU to adjust a UL transmission timing.

摘要： Symbols are to be recovered from signals received in a shared spectrum. Codes of the signals received in the shared spectrum are processed using a block Fourier transform (FT), producing a code block diagonal matrix. A channel response of the received signals is estimated. The channel response is extended and modified to produce a block circulant matrix and a block FT is taken, producing a channel response block diagonal matrix. The code block diagonal matrix is combined with the channel response block diagonal matrix. The received signals are sampled and processed using the combined code block diagonal matrix and the channel response block diagonal matrix with a Cholesky algorithm. A block inverse FT is performed on a result of the Cholesky algorithm to produce spread symbols. The spread symbols are despread to recover symbols of the received signals.

摘要： A circuit for use in a receiver receives a plurality of code division multiple access data signals simultaneously. Each data signal experiences a similar channel response. The circuit receives a combined signal over the shared spectrum in a time slot. The combined signal comprises the plurality of data signals. The combined signal is sampled at a multiple of a chip rate of the combined signal. The similar channel response is estimated. A channel response matrix or a channel correlation matrix is constructed based in part on the estimated channel response. A spread data vector is determined based in part on a fast Fourier transform (FFT) decomposition of a circulant version of the channel response matrix or channel correlation matrix. The spread data vector is despread to recover data from the matrix.
