#$%^&*AU2014203765A120140731.pdf#####ABSTRACT A method and apparatus for utilizing a plurality of uplink carriers and downlink carriers are disclosed. A wireless transmit/receive unit (WTRU) activates a 5 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, 10 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 15 secondary uplink carrier.s1l0 ca cC CL0 ~ cruj 2:2 :z Q Lu
