1. A method for enabling of hybrid automatic repeat request (HARQ) operations on channels between stations of an orthogonal frequency division multiple access (OFDMA) wireless communication network, comprising the steps of:

  • increasing adaptively a number of parallel HARQ channels to improve a performance of the HARQ operations;

    using one connection identifier to unambiguously identify a set of MAC protocol data units (MPDUs) communicated over parallel HARQ channels; and

    using sequence numbers to avoid out-of-order delivery when MPDUs are transmitted over the parallel HARQ channels.
