METHOD AND APPARATUS FOR DYNAMICALLY ALLOCATING H-ARQ PROCESSES
First Claim
1. A method for supporting enhanced uplink (EU) transmissions, implemented in a wireless transmit/receive unit (WTRU), comprising:
- providing hybrid automatic repeat request (H-ARQ) processes for supporting transmission over an enhanced dedicated channel (E-DCH), wherein at least one H-ARQ process is reserved for a dedicated channel medium access control channel (MAC-d) flow;
receiving H-ARQ information, wherein the information indicates H-ARQ processes for which transmission of data from the MAC-d flow is allowed;
for each transmission time interval (TTI), allocating an H-ARQ process for use by the MAC-d flow, from the allowed H-ARQ processes; and
transmitting data from the MAC-d flow over the E-DCH using the allocated H-ARQ process.

Abstract
A method and apparatus for supporting enhanced uplink (EU) transmissions, implemented in a wireless transmit/receive unit (WTRU), is disclosed. The WTRU provides hybrid automatic repeat request (H-ARQ) processes for supporting transmission over an enhanced dedicated channel (E-DCH), wherein at least one H-ARQ process is reserved for a dedicated channel medium access control channel (MAC-d) flow. The WTRU receives H-ARQ information, wherein the information indicates H-ARQ processes for which transmission of data from the MAC-d flow is allowed. For each transmission time interval (TTI), the WTRU allocates an H-ARQ process for use by the MAC-d flow, from the allowed H-ARQ processes. The WTRU transmits data from the MAC-d flow over the E-DCH using the allocated H-ARQ process.
