ABSTRACT:
A wireless communication apparatus includes management units and a decision unit. The apparatus is capable of receiving a plurality of items of data each including data frames each transmitted from the same data transmitter and managed under the same traffic identifier. The apparatus acknowledges the transmission of the data for the data transmitter in response to the reception of the data. Each of the management units holds acknowledgement information to acknowledge the transmission for each of the items of data. The decision unit, when the data is newly received, causes any one of the management units whose information amount of the acknowledgement information already held is smaller not only to discard the acknowledgement information but also to hold the acknowledgement information on the newly received data.
