Claim:
1. A network entity for reconfiguring a wireless transmit/receive unit (WTRU), the network entity comprising: a receiver, a transmitter, and a processor configured to: determine whether to reconfigure the WTRU, which is operating according to a first medium access control (MAC) protocol, to a second MAC protocol; and upon determination to reconfigure the WTRU from the first MAC protocol to the second MAC protocol, send an instruction to the WTRU via the transmitter so that the WTRU performs a MAC reset, wherein the first MAC protocol is MAC e/es and the second MAC protocol is an enhanced MAC e/es with an improvement over MAC e/es; and wherein performing the MAC reset comprises changing the first MAC protocol to the second MAC protocol at the WTRU, flushing all HARQ processes in the WTRU and discarding all segments in a segmentation buffer; wherein the improvement comprises an ability to communicate flexible size PDUs by utilizing an adaptation layer between MAC e/es and enhanced MAC e/es, wherein a header in PDUs of the enhanced MAC-e/es comprises a segmentation description field indicating whether a first and last part of the enhanced MAC-e/es are segments or full PDUs.
