An approach for providing bundled transmission is disclosed. A logic allocates a plurality of transmission time intervals (TTIs) of a time duplex division (TDD) transmission scheme as a bundle for supporting transmission of duplicate data over the TTIs. The bundle of TTIs is associated with a plurality of initial hybrid automatic repeat request (HARQ) processes. The logic also maintains one or more of the same initial HARQ processes as unbundled for a predetermined TDD configuration.
