1 . A method of selecting an enhanced uplink (EU) transport format combination (E-TFC), the method comprising:
 determining a number of scheduled data bits for an upcoming transmission, wherein the number of scheduled data bits is derived at least from a serving grant multiplied by a transport block size of a j th  TFC, a β value associated with the j th  TFC, and a β c  value.   
     
     
         2 . The method of  claim 1 , wherein the β value associated with the j th  TFC and the β c  value are squared. 
     
     
         3 . The method of  claim 1 , further comprising selecting a power offset (PO) for the upcoming transmission associated with a medium access control (MAC-d) flow that allows highest-priority data to be transmitted. 
     
     
         4 . The method of  claim 1 , further comprising:
 selecting a medium access control (MAC-d) flow; and   identifying other MAC-d flows for which data can be multiplexed.   
     
     
         5 . The method of  claim 1 , wherein the β c  value is a gain factor related to a Dedicated Physical Control Channel (DPCCH). 
     
     
         6 . A wireless transmit/receive unit (WTRU) configured to select an enhanced uplink (EU) transport format combination (E-TFC), the WTRU configured to:
 determine a number of scheduled data bits for an upcoming transmission, wherein the number of scheduled data bits is derived at least from a serving grant multiplied by a transport block size of a j th  TFC, a β value associated with the j th  TFC, and a β c  value.   
     
     
         7 . The WTRU of  claim 6 , wherein the β value associated with the j th  TFC and the β c  value are squared. 
     
     
         8 . The WTRU of  claim 6 , wherein the WTRU is further configured to select a power offset (PO) for the upcoming transmission associated with a medium access control (MAC-d) flow that allows highest-priority data to be transmitted. 
     
     
         9 . The WTRU of  claim 6 , wherein the WTRU is further configured to:
 select a medium access control (MAC-d) flow; and   identify other MAC-d flows for which data can be multiplexed.   
     
     
         10 . The WTRU of  claim 6 , wherein the β c  value is a gain factor related to a Dedicated Physical Control Channel (DPCCH).
