A wireless communication apparatus includes a received frame analysis unit, a received frame bitmap information storage unit, a bitmap reset determination unit, a Block Ack frame generation unit, and a TID bitmap storage unit. The received frame analysis unit analyzes a received MAC frame. The received frame bitmap information storage unit stores delivery acknowledgement of the received MAC frame. The bitmap reset determination unit determines whether or not information stored in the received frame bitmap information storage unit should be reset or not. The Block Ack frame generation unit generates a Block Ack frame including a bitmap to be stored in the received frame bitmap information storage unit on the basis of the delivery acknowledgement request analyzed by the received frame analysis unit. The TID bitmap storage unit stores an identifier of a frame allowing the received frame bitmap information storage unit to store the delivery acknowledgement.
