Patent ID: 8316269

Claim:
A method to perform hybrid automatic repeat request (HARQ) indexing, the method comprising: transmitting a non-user-specific advanced map (A-MAP) comprising a HARQ feedback index parameter (HFIP) to a mobile station in a first sub-frame, wherein the A-MAP contains unicast service control information; transmitting an assignment A-MAP comprising a partial HARQ feedback A-MAP (HF-A-MAP) index to the mobile station in the first sub-frame; receiving uplink data in a second sub-frame from the mobile station according to scheduling in the assignment A-MAP targeted for the mobile station; and calculating a full HARQ feedback index using both the HFIP and the partial HARQ feedback A-MAP index by calculating (P(j)+n)mod N HF-A-MAP , (where j is the value found in the HFIP, P(j) is a function of j, n is the value found in the partial HF-A-MAP index, and N HF-A-MAP is the total number of HF-A-MAPs configured.
