A technique for transmitting data in a communication network employing Hybrid Automatic Repeat Request includes a first step 502 of grouping data to be transported into a first and second groups in accordance to a decision parameter, such as data size. A next step 504 concatenates data from the first group and encodes into a multi-user packet. A next step 502 encodes the data into a plurality of data packets. A next step 506 assigns available traffic resources to encoded packets. A next step 506 transmits the encoded packets. A next step 510 reassigns a portion of said traffic resources for which a positive acknowledgement has been determined to uninitiated packets or to assist with one or more ongoing transmissions.
