Abstract

A wireless communication apparatus is used in a wireless communication system in which carrier sensing, and an exchange of a transmission request signal and a transmission permission signal are performed in order to perform wireless communication. The wireless communication apparatus includes: a reception unit that is capable of receiving multiple signals simultaneously; and a control unit that generates an acknowledgement response to a data signal on a priority basis in a case where the data signal and a transmission request signal are included in signals received by the reception unit.

Claims

1-11. -11. (canceled)

12. A wireless communication apparatus used in a wireless communication system in which a carrier sense, and an exchange of a transmission request signal and a transmission permission signal are performed in order to perform wireless communication, the wireless communication apparatus comprising:

a reception unit that is capable of receiving multiple signals simultaneously; and

a control unit that generating an acknowledgement response to a data signal on a priority basis

in a case where the data signal and a transmission request signal are included in signals received by the reception unit.

13. The wireless communication apparatus according to claim 12,

wherein, in a case where a transmission inhibition period included in the transmission request signal is larger than a predetermined value, after the acknowledgement response to the data signal has been made, the control unit transmits a transmission permission signal corresponding to the transmission request signal.

14. The wireless communication apparatus according to claim 13, wherein, at a time when the control unit transmits the transmission permission signal, the control unit includes, in the transmission permission signal, a value obtained by subtracting a predetermined value from the transmission inhibition period included in the transmission request signal, and transmits the transmission permission signal.

15. A wireless communication method in which a carrier sense and an exchange of a transmission request signal and a transmission permission signal are performed in order to perform wireless communication, the wireless communication method comprising the step of,

in a case where signals including a data signal and a transmission request signal are received, generating an acknowledgement response to the data signal on a priority basis.

16. A wireless communication apparatus used in a wireless communication system in which carrier sensing, and an exchange of a transmission request signal and a transmission permission signal are performed in order to perform wireless communication, the wireless communication apparatus comprising

a control unit that performs control so that, after a transmission request signal has been transmitted, in a case where data transmission is unable to be performed, even in a case where a signal in which a wireless communication apparatus other than the wireless communication apparatus itself is configured as a destination is received, retransmission is not performed for a predetermined period.

17. The wireless communication apparatus according to claim 16,

wherein the predetermined period is a transmission inhibition period used when the transmission request signal was transmitted.
