1. A method for multiplexing data implemented by a wireless transmit/receive unit (WTRU), the method comprising:

  • receiving a serving grant, wherein the serving grant is a grant for scheduled data transmission;

    receiving at least one non-scheduled grant, wherein the non-scheduled grant is a grant for non-scheduled data transmission;

    determining an available payload amount for a medium access control for enhanced uplink (MAC-e) protocol data unit (PDU), wherein the available payload amount is the smaller of;

    a maximum supported payload amount and a first amount of data, wherein the first amount of data is based on the serving grant and the at least one non-scheduled grant; and

    multiplexing bits from a medium access control for dedicated channel (MAC-d) flow into the MAC-e PDU;

    wherein the multiplexing is based on logical channel priority, wherein a higher priority logical channel is selected before a lower priority logical channel;

    wherein on a condition that the selected logical channel is associated with a non-scheduled MAC-d flow, the MAC-e PDU is filled with bits from the non-scheduled MAC-d flow up to the smaller of;

    an amount of data allowed by the non-scheduled grant for the non-scheduled MAC-d flow, an amount of data available for the selected logical channel, and the available payload amount; and

    wherein on a condition that the selected logical channel is associated with a scheduled MAC-d flow, the MAC-e PDU is filled with bits from the scheduled MAC-d flow up to the smaller of;

    an amount of data allowed by the serving grant, an amount of data available for the selected logical channel, and the available payload amount reduced by a quantization amount.
