A wireless transmit/receive unit (WTRU) sending a first data signal via an enhanced dedicated channel (E-DCH) is provided. The WTRU may reconfigure physical channel parameters based on a reconfiguration message. The WTRU may subsequently send a second data signal without performing a synchronization procedure. 1. A method performed by a wireless transmit/receive unit (WTRU) , the method comprising:sending, by the WTRU, a first data signal via an enhanced dedicated channel (E-DCH);reconfiguring, by the WTRU, physical channel parameters based on a reconfiguration message received in a radio resource control (RRC) signal; andsending, by the WTRU, a second data signal without performing a synchronization procedure.2. The method of further comprising:sending, by the WTRU, the first data signal via the E-DCH while the WTRU is in a CELL_FACH state; andtransitioning, by the WTRU, to a CELL_DCH state from the CELL_FACH state, wherein the WTRU transitions to the CELL_DCH state without performing the synchronization procedure.3. The method of further comprising:sending, by the WTRU, the second data signal in response to transitioning to the CELL_DCH state.4. The method of further comprising:sending, by the WTRU, control information in the CELL_DCH state via the E-DCH.5. The method of further comprising:setting, by the WTRU, an uplink transmit power level in the CELL_DCH state, wherein the power level is based on a transmit power used prior to transitioning to the CELL_DCH state.6. The method of further comprising:reporting, by the WTRU, in-synch and out-of-synch parameters in response to the RRC signal.7. The method of further comprising:receiving, by the WTRU, an uplink scrambling code assignment; andsending, by the WTRU, the second data signal using the received uplink scrambling code.8. The method of further comprising:monitoring, by the WTRU, a fractional dedicated physical channel (F-DPCH) for a transmit power control (TPC) command.9. The method of wherein the ...
