Wireless communication apparatus
A wireless communication apparatus includes a transmitter that transmits a first frame and a second frame with multiplexing and a receiver that receives a third frame sent in response to the first frame and a forth frame sent in response to the second frame, wherein a first receipt completion timing at which the third frame is fully received by the receiver and a second receipt completion timing at which the forth frame is fully received by the receiver are synchronized by controlling at least one of first content of the first frame, a first transmission method by which the first frame is sent, second content of the second frame and a second transmission method by which the second frame is sent.
1. A wireless communication apparatus comprising:
a transmitter configured to, by multiplexing, transmit a first frame to a first wireless apparatus and a second frame to a second wireless apparatus; and
a receiver configured to receive a third frame from the first wireless apparatus and a fourth frame from the second wireless apparatus,
wherein a length of the third frame is varied based on at least first content of the first frame,
a length of the fourth frame is varied based on at least second content of the second frame,
a temporal difference between a first receipt completion time at which the third frame is fully received by the receiver and a second receipt completion time at which the fourth frame is fully received by the receiver is less than a predetermined time length.
2. The apparatus of claim 1 ,
wherein at least one of the first content of the first frame or the second content of the second frame is controlled such that the temporal difference is less than the predetermined time length.
3. The apparatus of claim 1 ,
wherein the first content of the first frame is information for setting transmission rate of the third frame and the second content of the second frame is transmission rate of the fourth frame.
4. The apparatus of claim 1 ,
wherein the first content of the first frame is information for setting a frame type of the third frame and the second content of the second frame is information for setting a frame type of the fourth frame.
5. The apparatus of claim 4 ,
wherein the frame type of the third frame is an Ack policy for the third frame and the frame type of the fourth frame is an Ack policy for the fourth frame.
6. The apparatus of claim 1 ,
wherein the first content of the first frame is information for setting a number of TID of the third frame and the second content of the second frame is information for setting a number of TID of the fourth frame.
7. The apparatus of claim 1 ,
wherein the first content of the first frame is information included in a header of the first frame and the second content of the second frame is information included in a header of the second frame.
8. The apparatus of claim 1 ,
wherein the length of the third frame and the length of the fourth frame are varied based on a combination of the first wireless apparatus and the second wireless apparatus.
9. The apparatus of claim 1 , further comprising:
at least one antenna for transmitting a radio wave.
10. The apparatus of claim 1 ,
wherein the temporal difference is zero.
11. A wireless communication apparatus comprising:
a transmitter configured to, with multiplexing, transmit a first frame to a first wireless apparatus and a second frame to a second wireless apparatus; and
a receiver configured to receive a third frame from the first wireless apparatus and a fourth frame from the second wireless apparatus,
wherein the transmitter is further configured to transmit notification information,
a length of the third frame is varied based on the notification information,
a length of the fourth frame is varied based on the notification information, and
a temporal difference between a first receipt completion time at which the third frame is fully received by the receiver and a second receipt completion time at which the fourth frame is fully received by the receiver is less than a predetermined time length.
12. The apparatus of claim 11 ,
wherein the notification information is controlled such that the temporal difference is less than the predetermined time length.
13. The apparatus of claim 11 ,
wherein the notification information is information indicating transmission rate of the third frame and transmission rate of the fourth frame.
14. The apparatus of claim 11 ,
wherein the length of the third frame and the length of the fourth frame are varied based on a combination of the first wireless apparatus and the second wireless apparatus.
15. The apparatus of claim 11 ,
wherein the length of the third frame is varied based on the first wireless apparatus.
16. The apparatus of claim 11 , further comprising:
at least one antenna for transmitting a radio wave.
17. The apparatus of claim 11 ,
wherein the temporal difference is zero.
18. A wireless communication apparatus comprising:
a transmitter configured to transmit a first frame including first information for a first wireless apparatus and second information for a second wireless apparatus; and
a receiver configured to receive a second frame from the first wireless apparatus and a third frame from the second wireless apparatus,
wherein a length of the second frame is varied based on at least the first information and a length of the third frame is varied based on at least the second information,
a temporal difference between a first receipt completion time at which the second frame is fully received by the receiver and a second receipt completion time at which the third frame is fully received is less than a predetermined time length.
19. The apparatus of claim 18 , further comprising:
at least one antenna for transmitting a radio wave.
20. The apparatus of claim 18 ,
wherein the temporal difference is zero.
