ABSTRACT:
A communication apparatus includes a receiving unit that receives a data frame including a plurality of pieces of unit data and transmitted from a communication partner; a determining unit that determines whether there is data loss, for each piece of unit data included in the data frame received by the receiving unit; a transmission right acquiring unit that acquires a transmission right; and a generating unit that generates grant data for granting the transmission right acquired by the transmission right acquiring unit to the communication partner, when the determining unit determines that at least any one of the pieces of unit data has been lost.
