Method and apparatus for forwarding non-consecutive data blocks in enhanced uplink transmissions

A wireless network device comprising:

• a medium access control (MAC) entity;
• a hybrid automatic repeat request (HARQ) entity;
• and
• an entity higher than the MAC entity, wherein the wireless network device is configured to:
• receive a plurality of data blocks from a wireless transmit/receive unit (WTRU) over an uplink channel using a hybrid automatic repeat request (HARQ) entity, wherein each of the data blocks is associated with a frame number and a sequence number;
• initialize a timer in response to a determination that the data blocks, when stored in a buffer, include non-consecutive data blocks and the non-consecutive data blocks have a missing data block;
• and
• forward non-consecutive the data blocks in the buffer to the entity higher than the MAC entity on a condition that the timer has expired and the missing data block has not been received by the wireless network device,
• wherein the non-consecutive data blocks in the buffer include one or more data blocks having a sequence number higher than a sequence number of the missing data block.
