A method and apparatus for forwarding non-consecutive data blocks in enhanced uplink (EU) transmissions. A wireless transmit/receive unit (WTRU) and one or more Node-Bs include one or more automatic repeat request (ARQ)/hybrid-ARQ (H-ARQ) processes for supporting an enhanced dedicated channel (E-DCH). Data blocks transmitted by the WTRU are re-ordered in a re-ordering entity located in the Node-B(s) or a radio network controller (RNC). Once a missing data block is identified, a data forwarding timer in the Node-B(s) or RNC is initiated and subsequent WTRU transmissions are monitored to determine whether the missing data block has been discarded by the WTRU. Upon recognition of the discard of the missing data block, the non-consecutive data blocks are forwarded to higher layers.

What is claimed is: 1. A method of receiving uplink data by a wireless network device, the method comprising:receiving uplink signals using at least one hybrid automatic repeat request (HARQ) entity of a wireless network device;sending, by the wireless network device using at least one HARQ entity,

What is claimed is: 1. A method of receiving uplink data by a wireless network device, the method comprising:receiving uplink signals using at least one hybrid automatic repeat request (HARQ) entity of a wireless network device;sending, by the wireless network device using at least one HARQ entity, positive acknowledgement messages or negative acknowledgement messages over a downlink signaling channel in response to the received uplink signals;recovering protocol data units (PDUs) by the wireless network device from the received uplink signals;storing the recovered PDUs in at least one reordering buffer of the wireless network device;starting a timer of the wireless network device in response to identifying an out-of-order PDU based on at least sequence numbers of the recovered PDUs; andon a condition that a missing PDU is not recovered before the timer expires, delivering by the wireless network device at least one recovered PDU to higher layers in response to the timer expiring.
