摘要： A method and apparatus for supporting transmit diversity are disclosed. A wireless communication system includes a transmitter having a plurality of transmit antennas and a receiver having at least one receive antenna. The transmitter transmits different pilot code sequences via each of the transmit antennas. The receiver comprises at least one receive antenna for receiving signals transmitted from the transmitter and a plurality of equalizers. Each equalizer is locked onto one of the transmit antennas and processes received samples using a corresponding pilot code sequence. The equalizer may treat user data and pilot code sequence transmitted via all other transmit antennas except the corresponding transmit antenna as interference or alternatively may cancel pilot or pilot and data in parallel or successively.

摘要： A receiver which includes at least one equalizer filter and a tap coefficients generator for implementing receive diversity. The equalizer filter processes a signal derived from signals received by a plurality of antennas. In one embodiment, sample data streams from the antennas are merged into one sample data stream. The merged sample data stream is processed by a single extended equalizer filter, whereby filter coefficients are adjusted in accordance with a joint error signal. A filter coefficient correction term used by the equalizer filter is generated by the tap coefficients generator using a normalized least mean square (NLMS) algorithm. In another embodiment, a plurality of equalizer filters are utilized, whereby each equalizer receives a sample data stream from a specific one of the antennas. In yet another embodiment, the sample data streams are combined after being processed by a plurality of matched filters based on respective estimated channel impulse responses.

摘要： A wireless communication method and apparatus for decoding an enhanced uplink 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 10ms 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型上行链路专用信道（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部分在节点B处用WTRU身份（ID）掩蔽。 CRC部分和数据部分被解复用，CRC部分用WTRU ID去掩码。然后使用去掩码的CRC部分执行CRC。如果CRC通过，则数据部分被发送到增强型上行链路媒体接入控制（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E-AGCH数据通过10ms帧发送时，如果CRC失败，则通过后续子帧的E-AGCH数据可以与先前的E-AGCH数据软结合。

摘要： A wireless communication method and apparatus for detecting and decoding enhaiced dedicated channel (E-DCH) hybrid automatic repeat request (H-ARQ) indicator channel (E-HICH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-HICH transmissions (202) and detects an H-ARQ indicator transmitted via the E-HICH by performing a binary hypothesis test (204). The WTRU then generates an acknowledgement (ACK) message or a non acknowledgement (NACK) message based on the detected H-ARQ indicator (206). A reliability test may be further performed to improve performance, whereby the binary hypothesis test may be performed only if the reliability test is passed.

摘要： A method and apparatus for automatically correcting the frequency of a local oscillator of a receiver. A primary common pilot channel (CPICH) code sequence is generated by a CPICH code generator based on a reference cell identification signal and a frame start signal. The received despread CPICH code sequence is used to generate an estimated frequency error signal. A control voltage generator based on the estimated frequency error signal generates a control voltage signal. The CPICH code generator generates the CPICH code sequence based on signals received from a high speed downlink packet access (HSDPA) serving cell when HSDPA is active, or a timing reference cell when HSDPA is not active. The present invention achieves full maximum ratio combining gain when space-time transmit diversity (STTD) is used, even without receiving a transmit diversity indication.

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)E-AGCH signals to detect an absolute grant, and decodes E-DCH relative grant channel (E-RGCH)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. A reliability test may be further performed on the E-RGCH signals.

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 sliding window based data estimation is performed. An error is introduced in the data estimation to the communication modeling the relationship between the transmitted and received signals. To compensate for an error in the estimated data, the data that was estimated in a previous sliding window step (58) or terms that would otherwise be truncated as noise are used. These techniques (50, 52, 54, 56. 58, 60, 62 and 64) allow for data to be truncated prior to further processing reducing the data of the window.

摘要： A method for biasing signal-to-interference ratio (SIR) to generate channel quality indicator (CQI) includes measuring the packet error rate (PER) of a received signal and comparing the PER to a to the target PER to generate a correction term. The correction term is combined with the SIR estimation of a reference channel to generate a CQI. The CQI is reported to a transmitter to adjust signal configurations, such as code rate, modulation type, number of codes, power offset.

摘要： The present invention is related to a method and apparatus for estimating signal-to-noise ratio (SNR) based on dedicated physical channel (DPCH) pilot symbols in a wireless communication system. A receiver receives a DPCH transmission and a despreader despreads the received DPCH transmission. A selector selects pilot symbols in the despread DPCH transmission. A signal power estimator estimates signal power based on the pilot symbols, and a noise power estimator estimates noise power based on the received DPCH transmission. A SNR estimator estimates an SNR based on the signal power estimation and the noise power estimation. The noise power estimator may calculate the noise power estimation either based only on pilot symbols or based on both pilot symbols and non-pilot symbols. The DPCH transmission may be transmitted using more than one antenna for transmit diversity.
