1. A wireless communication apparatus comprising:
- a transmission section which transmits data using wireless communication;
a control section which controls a transmission rate for the transmission section, the control section limiting data size of data to be transmitted to at most a prescribed value and requesting a transmission acknowledgement, during a period from immediately after a change in the transmission rate until number of times that the transmission section transmits data reaches a prescribed number of times; and
a frame generation section which generates a frame of the data to be transmitted and which aggregates a plurality of the frames,wherein the transmission section transmits the frame generated by the frame generation section or the plurality of frames aggregated by the frame generation section, andduring the period until the number of times that the frame is transmitted reaches the prescribed number of times, the control section prohibits the frame generation section from aggregating the frames, while instructing the frame generation section to generate the frame as a frame requesting the transmission acknowledgement.

Abstract
A wireless communication apparatus includes a transmission section and a control section. The transmission section transmits data using wireless communication. The control section controls a transmission rate for the transmission section. The control section limits data size of data to be transmitted to at most a prescribed value and requests a transmission acknowledgement, during a period from immediately after a change in the transmission rate until number of times that the transmission section transmits data reaches a prescribed number of times.

7. A wireless communication apparatus comprising:
-
a transmission section which transmits data using wireless communication; a control section which controls a transmission rate for the transmission section, the control section limiting data size of data to be transmitted to at most a prescribed value and requesting a transmission acknowledgement, during a period from immediately after a change in the transmission rate until number of times that the transmission section transmits data reaches a prescribed number of times; and a frame generation section which generates a frame of data received from a data generation section generating the data to be transmitted, wherein the transmission section transmits the frame generated by the frame generation section, and during the period until the number of times that the frame is transmitted reaches the prescribed number of times, the control section instructs the data generation section to limit the data size of the data to be transmitted to at most the prescribed value, while instructing the frame generation section to generate the frame as a frame requesting the transmission acknowledgement. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A wireless communication method comprising:
-
changing a data transmission rate according to a status of a transmission path; starting counting number of times that data is transmitted, immediately after a change in a transmission rate; and limiting data size of data to be transmitted to at most a prescribed value and requesting transmission acknowledgement, during a period until the number of times that the data is transmitted reaches a prescribed number of times, wherein the data to be transmitted is assembled into a frame for transmission, and by preventing frames from being aggregated during the period until the number of times that the frame is transmitted reaches the prescribed number of times, the data size of the data to be transmitted is limited to at most the prescribed value, the method further comprising permitting aggregation of the frames after the number of times that the frame is transmitted reaches the prescribed number of times. - View Dependent Claims (15, 16)

17. A wireless communication method comprising:
-
changing a data transmission rate according to a status of a transmission path; starting counting number of times that data is transmitted, immediately after a change in a transmission rate; and limiting data size of data to be transmitted to at most a prescribed value and requesting transmission acknowledgement, during a period until the number of times that the data is transmitted reaches a prescribed number of times, wherein the data to be transmitted is assembled into a frame for transmission, and during the period until the number of times that the frame is transmitted reaches the prescribed number of times, a data generation section generating the data to be transmitted is instructed to limit the data size of the data to be transmitted to at most the prescribed value, the method further comprising permitting data of a data size greater than the prescribed value to be generated after the number of times that the frame is transmitted reaches the prescribed number of times. - View Dependent Claims (18, 19, 20)
