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 apparatus comprising:
a receiver configured to receive a first frame among a plurality of frames, the plurality of frames including the first frame and a second frame and being transmitted by multiplexing from a wireless communication apparatus,
a transmitter configured to transmit a third frame,
wherein a length of the third frame varies according to at least first content of the first frame,
a temporal difference between a first time at which the third frame is fully received by the wireless communication apparatus and a second time at which a fourth frame sent in response to the second frame is fully received by the wireless communication apparatus is less than a predetermined time length.
2. The apparatus of claim 1 , wherein the at least first content of the first frame is information for setting a transmission rate of the third frame.
3. The apparatus of claim 1 , wherein the at least first content of the first frame is information for setting a frame type of the third frame.
4. The apparatus of claim 1 , wherein the at least first content of the first frame is Ack policy for the third frame.
5. The apparatus of claim 1 , wherein the at least first content of the first frame is information for setting a number of traffic identifiers (TIDs) of the third frame.
6. The apparatus of claim 1 , wherein the at least first content of the first frame is information included in a header of the first frame.
7. The apparatus of claim 1 , wherein the temporal difference is zero.
8. The apparatus of claim 1 , further comprising:
at least one antenna for transmitting a radio wave.
9. A wireless apparatus comprising:
a receiver configured to receive a first frame among a plurality of frames, the plurality of frames including the first frame and a second frame and being transmitted by multiplexing from a wireless communication apparatus,
a transmitter configured to transmit a third frame,
wherein the receiver is configured to receive notification information from the wireless communication apparatus,
a length of the third frame varies according to the notification information,
a temporal difference between a first time at which the third frame is fully received by the wireless communication apparatus and a second time at which a fourth frame sent in response to the second frame is fully received by the wireless communication apparatus is less than a predetermined time length.
10. The apparatus of claim 9 , wherein the notification information is information for setting a transmission rate of the third frame.
11. The apparatus of claim 9 , wherein the temporal difference is zero.
12. The apparatus of claim 9 , further comprising:
at least one antenna for transmitting a radio wave.
13. A wireless communication method comprising:
receiving, by a receiver, a first frame among a plurality of frames, the plurality of frames including the first frame and a second frame transmitted by multiplexing from a wireless communication apparatus;
transmitting, by a transmitter, a third frame; and
receiving, by the receiver, notification information from the wireless communication apparatus,
wherein a length of the third frame varies according to the notification information,
and
a temporal difference between a first time at which the third frame is fully received by the wireless communication apparatus and a second time at which a fourth frame is fully received by the wireless communication apparatus is less than a predetermined time length.
14. The method of claim 13 , wherein the notification information is information for setting a transmission rate of the third frame.
15. The method of claim 13 , wherein the temporal difference is zero.
16. The method of claim 13 , further comprising:
transmitting, by at least one antenna, a radio wave.
17. A wireless communication method comprising:
receiving a first frame among a plurality of frames, the plurality of frames including the first frame and a second frame and being transmitted by multiplexing from a wireless communication apparatus,
transmitting a third frame,
wherein a length of the third frame varies according to at least first content of the first frame, and
a temporal difference between a first time at which the third frame is fully received by the wireless communication apparatus and a second time at which a fourth frame sent in response to the second frame is fully received by the wireless communication apparatus is less than a predetermined time length.
18. The method of claim 17 , wherein the at least first content of the first frame is information for setting transmission rate of the third frame.
19. The method of claim 17 , wherein the temporal difference is zero.
20. The method of claim 17 , wherein the at least first content of the first frame is information included in a header of the first frame.
