Patent ID: 8542596

Claim:
A method for setting a happy bit on an enhanced dedicated channel (E-DCH) dedicated physical control channel (E-DPCCH) in a wireless transmit/receive unit (WTRU), the method comprising: determining whether predetermined criteria are met and setting the happy bit to “unhappy” on a condition that the criteria are met, wherein when E-DCH improved medium access control (MAC-i/is) is configured and medium access control (MAC) segmentation is supported the criteria includes determining whether the WTRU has enough power available to transmit at a higher data rate and determining whether the WTRU has enough power available to transmit at the higher data rate comprises: identifying an E-DCH transport format combination (E-TFC) that has a transport block size at least x number of bits larger than a transport block size of a currently selected E-TFC selected for transmission in a same transmission time interval (TTI) as the happy bit; and determining whether the identified E-TFC is supported based on a same power offset as the currently selected E-TFC.
