Abstract
Systems and methodologies are described that facilitate utilizing hybrid automatic repeat/request (HARQ) in system access communications. A HARQ entity is provided that manages a plurality of HARQ processes, which can typically use new data indicators (NDI) to determine when received data is a new transmission or retransmission. For resource grants, the HARQ entity can determine whether the communication is a new transmission or retransmission based on the type of message that contains the grant. In addition, an address comprised within the message, a previous use of the HARQ process, and/or the like can further be utilized to determine whether the message is a new transmission or retransmission. Once determined, the HARQ entity can provide the message to the appropriate HARQ process along with the indication of new transmission or retransmission.
