    摘要: A hybrid orthogonal frequency division multiple access (OFDMA) wireless transmit/receive unit (WTRU) and method are disclosed. A WTRU includes a transmitter and a receiver. The receiver processes received data to recover data mapped to the subcarriers using OFDMA. The receiver recovers first input data by separating user data from multi-user spread data and recovers second input data from non-spread 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.

    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: Methods for signaling multi-user multiple-input multiple output (MU-MIMO) parameters for Evolved-UTRA (E-UTRA) are disclosed. Example signaling format methods are presented that allow use of distributed virtual resource blocks (DVRB) or support of four wireless transmit/receive units (WTRUs) but maintaining a predetermined signal format size. A signaling format is also presented that signals transmission precoding matrix indexes used by all co-scheduled WTRUs.

    摘要: A method and apparatus for processing enhanced uplink scheduling grants are disclosed. A wireless transmit/receive unit (WTRU) detects an absolute grant (AG) and a relative grant (RG). Once the WTRU detects an AG or a RG, a new serving grant (SG) is generated and a hybrid automatic repeat request process may be activated or deactivated depending on whether the received AG is a primary AG or a secondary AG, whether a scheduling mode is a primary AG mode or a secondary AG mode, whether an AG value is set to “INACTIVE” and whether a transmission time interval is 2 ms or 10 ms. A Node-B may send a secondary AG to the WTRU before switching from a primary AG mode to a secondary AG mode and may send the secondary AG only if there is no out-of-date secondary AG exists, which may be detected by implementing a time threshold.
