Wireless communication method of selecting an enhanced uplink transport format combination

A wireless transmit/receive unit (WTRU) configured to select an enhanced uplink (EU) transport format combination (E-TFC), the WTRU configured to:

• determine a maximum number of bits of scheduled data for an upcoming transmission calculated from Ke,ref, wherein the highest value is lower or equal to:
• K
• e
• ,
• ref
• ·
• SG
• L
• e

• 10
• Δ

• 
• ,
• where SG is a serving grant, Le,ref is the number of EU dedicated physical data channels (E-DPDCHs) used for a selected reference E-TFC, Ke,ref is the number of data bits of the reference E-TFC, Δharq is a hybrid automatic repeat request (HARQ) offset for a specific data flow to be transmitted as signaled by higher layers, and Aed,ref is a ratio derived from a parameter ΔE-DPDCH signaled by higher layers for the selected reference E-TFC.

A method of selecting an enhanced uplink (EU) transport format combination (E-TFC), the method comprising:

• determining a maximum number of bits of scheduled data for an upcoming transmission, wherein the highest value is lower or equal to a product of:
• a ratio of the serving grant (SG) over the number of EU dedicated physical data channels (E-DPDCHs) used for a selected reference E-TFC, a hybrid automatic repeat request (HARQ) offset for a specific data flow to be transmitted as signaled by higher layers, and a ratio derived from a parameter ΔE-DPDCH signaled by higher layers for the selected reference E-TFC;
• and
• the number of data bits of the reference E-TFC.
