8. A wireless transmit/receive unit (WTRU) comprising:
a media access control (MAC);
a radio resource control (RRC) connected to the MAC and configured to receive an active set update message indicating whether to operate in a predetermined modulation mode, wherein the predetermined modulation mode is 16-symbol quadrature amplitude modulation (16QAM); and
a physical layer (PHY) connected to the RRC; the RRC configured to indicate to lower layers to operate in or stop the predetermined modulation mode and perform at least one of:
interact with the MAC to perform a MAC-es/e reset procedure to clear buffers; and
identify an index that indicates an E-TFCI transport block size table.', 'a media access control (MAC);', 'a radio resource control (RRC) connected to the MAC and configured to receive an active set update message indicating whether to operate in a predetermined modulation mode, wherein the predetermined modulation mode is 16-symbol quadrature amplitude modulation (16QAM); and', 'a physical layer (PHY) connected to the RRC; the RRC configured to indicate to lower layers to operate in or stop the predetermined modulation mode and perform at least one of:', 'interact with the MAC to perform a MAC-es/e reset procedure to clear buffers; and', 'identify an index that indicates an E-TFCI transport block size table.
9. The WTRU of claim 8, wherein at least one of the RRC and PHY is configured to update an active set which indicates active cells available to the WTRU for communication
10. The WTRU of claim 8 wherein at least one of the RRC and PHY is configured to perform an updating of associated power offsets by modifying a power offset of an enhanced dedicated physical control channel (E-DPCCH) in response to the active set update message
11. The WTRU of claim 10, wherein at least one of the RRC and PHY is configured to perform the modifying the power offset of the enhanced dedicated physical control channel (E-DPCCH) by:
using a new value of the power offset if received in a separate IE included in the active set update message; and
using an existing value of the power offset if the separate IE is not included in the active set update message.', 'using a new value of the power offset if received in a separate IE included in the active set update message; and', 'using an existing value of the power offset if the separate IE is not included in the active set update message
12. The WTRU of claim 8 wherein at least one of the RRC and PHY is further configured to determine actions related to E-DPCCH boosting by modifying an E-TFCI threshold, wherein boosting of E-DPCCH is enabled if an E-TFCI value exceeds the E-TFCI threshold
13. The WTRU of claim 12 wherein at least one of the RRC and PHY is configured to modify the E-TFCI threshold by:
using a new value of the E-TFCI threshold if received in a separate IE included in the active set update message; and
using an existing value of the E-TFCI threshold if the separate IE is not included in the active set update message.', 'using a new value of the E-TFCI threshold if received in a separate IE included in the active set update message; and', 'using an existing value of the E-TFCI threshold if the separate IE is not included in the active set update message
14. The WTRU of claim 8, wherein at least one of the RRC and PHY is further configured for the modifying of the index that indicates the E-TFCI transport block size table by:
using the E-TFCI Transport Block Size table indicated by the index received in a separate IE included in the active set update message; and
