Utilizing HARQ for uplink grants received in wireless communications
First Claim
1. A method for interpreting hybrid automatic repeat/request (HARQ) functionality in system access procedures, comprising:
- receiving, at a device, a communication comprising a grant of data channel resources for communicating over a wireless network from an access point in the wireless network;
determining whether the grant in the communication is associated with a new transmission or a retransmission based at least in part on a communication type; and
providing the communication to a HARQ process along with an indicator for the new transmission based on the determination and whether a buffer of the HARQ process comprises a response to a system access response.

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.
