A wireless reception apparatus (200) for a wireless communication system which transmits, between an MBS transmission apparatus and MBS reception apparatus, multiple transport blocks (TB) coded by error correction coding at the physical layer or at both the physical layer and the data link layer. In the wireless reception apparatus (200), a feedback condition judgment unit (208) transmits feedback information to the MBS transmission apparatus when a reception judgment unit (206) detects errors in L or more TBs out of an N-number of TBs (N is a natural number while L is a natural number less than N) that constitute the beginning portion of any MAC FEC blocks where the beginning TB has been identified. In the wireless communication apparatus (100), the link adaptation unit (114), based on the feedback information from the wireless communication apparatus (200), adjusts the physical layer transmission parameters used for the TBs in the physical layer processing unit.
