摘要： A method and apparatus for performing uplink transmission in a multiple-input multiple-output (MIMO) single carrier frequency division multiple access (SC-FDMA) system are disclosed. At a wireless transmit/receive unit (WTRU), input data is encoded and parsed into a plurality of data streams. After modulation and Fourier transform, one of transmit beamforming, space time coding (STC) and spatial multiplexing is selectively performed based on channel state information. Symbols are then mapped to subcarriers and transmitted via antennas. The STC may be space frequency block coding (SFBC) or space time block coding (STBC). Per antenna rate control may be performed on each data stream based on the channel state information. At a Node-B, MIMO decoding may be performed based on one of minimum mean square error (MMSE) decoding, MMSE-successive interference cancellation (SIC) decoding and maximum likelihood (ML) decoding. Space time decoding may be performed if STC is performed at the WTRU.

摘要： A method and apparatus for scaling a soft bit for decoding in a wireless communication system are described. A scaling factor is calculated for a received symbol based on an estimated signal-to-noise ratio (SNR) of the received symbol and the scaling factor is applied to a soft bit of the received symbol. A multiple-input multiple-output (MIMO) scheme may be implemented to transmit multiple data streams. In such case, a soft bit of a received symbol on each data stream is scaled by a scaling factor for the received symbol on each data stream.

摘要： Joint detection is performed in a multi-user detector (MUD) using reduced length channel impulse responses and using interference cancellation (IC) in the dimension of delay spread as a whole, whereby several clusters of smaller delay spread are processed. Several clusters of real transmitted paths that are close to each other are grouped together and zeros that occur between the path cluster groups are discarded. Each cluster group has a much shorter delay spread and thus has smaller dimensions of system matrix A. Mutual interference occurring between the path cluster groups is eliminated by applying an interference cancellation technique.

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 method and apparatus for estimating channelization codes in a wireless transmit/receive unit (WTRU) using blind code detection (BCD). A WTRU receives communication bursts and detects a midamble in the received burst. A candidate code list is generated in accordance with the detected midamble. The candidate code list includes channelization codes intended for both the intended WTRU and other WTRUs. Active channelization codes among the codes in the candidate list are identified, and the identified codes are forwarded to a multi-user detector (MUD). The present invention resolves SF ambiguity in the downlink of TSM. Since the orthogonal variable spreading factor code maintains the orthogonality between codes of different SF, SFs of other WTRUs follow the SF of the intended WTRU. Moreover, since the data for other WTRUs is not used in symbol processing after MUD, the performance of MUD for the intended WTRU is preserved with the SF ambiguity of other WTRUs.
摘要翻译：一种使用盲码检测（BCD）估计无线发射/接收单元（WTRU）中的信道化码的方法和装置。 WTRU接收通信突发并检测接收到的突发中的中间码。根据检测到的中间码产生候选码列表。候选代码列表包括旨在用于预期的WTRU和其他WTRU的信道化代码。识别候选列表中的代码之间的主动信道化代码，并将所识别的代码转发到多用户检测器（MUD）。本发明解决了TSM下行链路中的SF模糊性。由于正交可变扩频因子码维持不同SF的码之间的正交性，其他WTRU的SF遵循预期的WTRU的SF。此外，由于在MUD之后的其他WTRU的数据不用于符号处理，所以对于预定的WTRU的MUD的性能被保留在其他WTRU的SF模糊度上。

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.
