    • A method and apparatus for processing multiple-input multiple-output (MIMO) transmission are disclosed. A wireless transmit/receive unit (WTRU) receives downlink control information including WTRU-specific MIMO and transport format information and MIMO information for all other WTRUs assigned to the same resource. The WTRU processes received MIMO data based on the downlink control information. The downlink control information may also include transport format information for all other WTRUs assigned to the same RB. The downlink control information may be transmitted via WTRU-specific control signaling. All WTRUs' MIMO and/or transport format information may be transmitted via resource-specific common control signaling. The downlink control signaling format may include at least one of a number of streams for the WTRU, a number of active WTRUs assigned to the same resource, a spatial channel identity for the WTRU, a MIMO mode, a precoding matrix index and a precoding vector index.

    • An orthogonal frequency division multiplexing (OFDM)-code division multiple access (CDMA) system is disclosed. The system includes a transmitter and a receiver. At the transmitter, a spreading and subcarrier mapping unit spreads an input data symbol with a complex quadratic sequence code to generate a plurality of chips and maps each chip to one of a plurality of subcarriers. An inverse discrete Fourier transform is performed on the chips mapped to the subcarriers and a cyclic prefix (CP) is inserted to an OFDM frame. A parallel-to-serial converter converts the time-domain data into a serial data stream for transmission. At the receiver, a serial-to-parallel converter converts received data into multiple received data streams and the CP is removed from the received data. A discrete Fourier transform is performed on the received data streams and equalization is performed. A despreader despreads an output of the equalizer to recover the transmitted data.

    • A wireless communication method and apparatus for scheduling data having different priorities for a plurality of wireless transmit/receive units (WTRUs), (i.e., users) is disclosed. The normalized average active throughput for each of the WTRUs is computed. Then, the normalized channel quality for each of the WTRUs is computed based on a reported channel quality indicator (CQI) and the respective normalized average active throughput. A sequence of WTRUs is arranged in an order of decreasing normalized channel quality for each data priority. As much of the data as possible is scheduled for the WTRUs in the order of decreasing normalized channel quality of WTRUs. The scheduling is performed until there are no more physical resources available. Several of the WTRUs can be scheduled in the same transmission timing interval (TTI) if there are enough physical resources.The normalized average active throughput of each WTRU is computed. The normalized channel quality of each WTRU is computed based on a channel quality indicator (CQI) and the respective normalized average active throughput. The data with the highest priority and the WTRU with the best normalized channel quality are selected. As much of the highest priority data as possible is scheduled for each WTRU. When sufficient physical resources are available, and there are no more WTRUs associated with the highest priority data, the data with the next highest priority and the WTRU with the best normalized channel quality that is not associated with the highest priority data are selected. Several WTRUs can be scheduled in the same transmission timing interval (TTI) if there are enough physical resources.

    • A method and apparatus for minimizing redundant enhanced uplink (EU) allocation requests and fault-tolerating EU transmission failures that occur between a wireless transmit/receive unit (WTRU) (102) and a Node-B (104). The WTRU (102) transmits an enhanced dedicated channel (E-DCH) allocation request to the Node-B (104) over an uplink (UL) EU channel (110). In one embodiment, if E-DCH allocation cannot be provided within a predetermined time period, the Node-B sends an acknowledgement message to the WTRU via a downlink (DL) EU signaling channel (112) without sending E-DCH allocation information. The request is queued in the Node-B and the WTRU refrains from transmitting the same request until after the time period expires or resources become available. In another embodiment, appropriate actions are taken to correct EU transmission failures by determining whether an E-DCH allocation request was unsuccessfully delivered via the UL EU channel or whether channel allocation information was unsuccessfully delivered via the DL EU signaling channel.
    • 一种用于最小化在无线发射/接收单元(WTRU)(102)和节点B(104)之间发生的冗余增强上行链路(EU)分配请求和容错EU传输失败的方法和装置。 WTRU(102)通过上行链路(UL)EU信道(110)向节点B(104)发送增强型专用信道(E-DCH)分配请求。 在一个实施例中,如果在预定时间段内不能提供E-DCH分配,则节点B经由下行链路(EU)信令信道(112)向WTRU发送确认消息,而不发送E-DCH分配信息。 该请求在节点B中排队,并且WTRU禁止发送相同的请求,直到时间段到期或资源变得可用。 在另一个实施例中,通过确定E-DCH分配请求是经由UL EU信道未成功传送还是经由DL EU信令信道未成功传送的信道分配信息被采取适当的动作来校正EU传输失败。
