Wireless communication method and apparatus for processing enhanced uplink scheduling grants
Abstract
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WTRU before switching from a primary AG mode to a secondary AG mode and may send the secondary AG only if there is no out-of-date secondary AG exists, which may be detected by implementing a time threshold.
