摘要： A method and apparatus for detecting an overlap of an E-DCH transmission or retransmission in TTIs that overlap with an assigned uplink compressed mode gap is disclosed. More specifically, detecting an overlap of an E-DCH transmission or retransmission in TTIs that overlap with an uplink compressed mode gap assigned by a Node B when a WTRU is configured with a 2 ms TTI is disclosed. After detecting the overlap of the E-DCH transmission or retransmission and the uplink compressed mode gap, the E-DCH transmission or retransmission is paused.

摘要： 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.

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： A method and system for implementing multi-user virtual multiple-input multiple-output (MIMO) techniques for wireless transmit/receive units (WTRUs) having one or more antennas are disclosed. The system includes a base station and at least one WTRU having at least two antennas. The number of antennas of the base station is not less than the number of antennas of any of the WTRUs. The base station generates a channel matrix for the WTRUs and processes received signals from the WTRUs based on a measurement of the channel matrix. The WTRUs may perform transmit precoding or eigen-beamforming using the channel matrix information. The WTRUs may also perform transmit diversity.

摘要： A multiple-input multiple-output (MIMO) beamforming-based single carrier frequency division multiple access (SC-FDMA) system is disclosed. At the transmitter, a fast Fourier transform (FFT) is performed on transmission data to generate frequency domain data. The frequency domain transmit data is mapped to assigned subcarriers. An inverse fast Fourier transform (IFFT) is performed on the transmit data mapped to the assigned subcarriers to generate time domain transmit data. The time domain transmit data is transmitted via antennas. At a receiver, an FFT is performed on the received data to generate frequency domain received data. Subcarrier demapping is performed to extract data mapped on the assigned subcarriers. A channel estimator generates a channel matrix which is decomposed into U, D and V H matrices. A channel distortion and interference between transmit and receive antennas are equalized based on the decomposed channel matrices to the extracted frequency domain received data.

摘要： A method and apparatus for controlling enhanced dedicated channel (E-DCH) transmissions are disclosed. An enhanced uplink medium access control (MAC-e/es) entity processes a received scheduling grant to calculate a serving grant. The MAC-e/es entity determines whether both a hybrid automatic repeat request (H-ARQ) process for scheduled data and scheduled data are available. If an H-ARQ process for scheduled data and scheduled data are available, the MAC-e/es entity determines whether a serving grant exists. The MAC-e/es entity calculates a remaining power based on maximum allowed power and restricts an E-DCH transport format combination (E-TFC) based on the remaining power. The MAC-e/es entity selects an E-TFC using the serving grant and generates a MAC-e protocol data unit. The MAC-e/es entity may process the received scheduled grant is at each transmission time interval or may store the received scheduled grant in a grant list until there is E-DCH data to transmit.
