Mac multiplexing and tfc selection procedure for enhanced uplink

A METHOD IMPLEMENTED IN A WIRELESS COMMUNICATION SYSTEM INCLUDING A WIRELESS TRANSMIT/RECEIVE UNIT (WTRU), A NODE-B AND A RADIO NETWORK CONTROLLER (RNC) FOR QUANTIZING MULTIPLEXED DATA ALLOWED BY GRANTS TO CLOSELY MATCH A SELECTED ENHANCED UPLINK TRANSPORT FORMAT COMBINATION (E-TFC) TRANSPORT BLOCK SIZE IS DISCLOSED. THE AMOUNT OF SCHEDULED AND NON-SCHEDULED DATA ALLOWED TO BE TRANSMITTED IS QUANTIZED SO THAT THE AMOUNT OF DATA MULTIPLEXED INTO AN ENHANCED UPLINK (EU) MEDIUM ACCESS CONTROL (MAC-E) PROTOCOL DATA UNIT (PDU) (1411) MORE CLOSELY MATCHES THE SELECTED E-TFC TRANSPORT BLOCK SIZE. IN AN EMBODIMENT, THE AMOUNT OF BUFFERED DATA ALLOWED TO BE MULTIPLEXED BY AT LEAST ONE GRANT, (A SERVING GRANT (1406)AND/OR A NON-SERVING GRANT), IS QUANTIZED SO THAT THE SUM OF SCHEDULED AND NON-SCHEDULED DATA INCLUDING MAC HEADER AND CONTROL INFORMATION MULTIPLEXED INTO A MAC-E PDU MORE CLOSELY MATCHES THE SELECTED E-TFC TRANSPORT BLOCK SIZE.
