Abstract: An efficient uplink HARQ feedback channel resource allocation scheme is adopted for carrier aggregation in a multi-carrier LTE/LTE-A system. Two resource allocation schemes (e.g., explicit and hybrid) for HARQ ACK/NACK (A/N) are applied. Part of the resources is allocated based on explicit method via RRC configuration.

The DL grant corresponds to transport blocks over a configured CC. The resource index points to a physical resource from a set of candidate uplink A/N physical resources reserved for the CC. In an implicit method, the A/N physical resources are determined based on a logical address of the DL scheduling grant.
