METHOD AND APPARATUS FOR UTILIZING A PLURALITY OF UPLINK CARRIERS AND A PLURALITY OF DOWNLINK CARRIERS
摘要
A method and apparatus for utilizing a plurality of uplink carriers and downlink carriers are disclosed. A wireless transmit/receive unit (WTRU) activates a primary uplink carrier and a primary downlink carrier and activates or deactivates a secondary uplink carrier based on a signal from a network or upon detection of a pre-configured condition. The WTRU may deactivate the secondary uplink carrier based on inactivity of the E-DCH transmission, a buffer status, a channel condition, or power constraints. When the secondary uplink carrier is activated, dedicated physical control channel (DPCCH) transmission may be initiated predetermined time periods prior to initiating E-DCH transmissions. The initial DPCCH transmission power may be set based on a DPCCH transmission power on the primary uplink carrier or to a value signaled by a network. A default grant value may be used for initial E-DCH transmission upon activation of the secondary uplink carrier.
