WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD
First Claim
1. A wireless communication apparatus comprising:
- a transmission unit that transmits a transmit signal in a condition where either acknowledgement or negative acknowledgement is set therein;
a reception unit that receives a positive acknowledgment signal or a negative acknowledgment signal in response to the transmission signal;
a counter that counts the number of times the reception unit has not received the negative acknowledgment signal in response to the transmission signal in which the negative acknowledgement is set; and
a control unit that causes the transmission unit to set the negative acknowledgement if a count value of the counter is less than a predetermined value and, if the count value is equal to or larger than the predetermined value, causes the transmission unit to set the acknowledgement.

Abstract
A wireless communication apparatus has a transmission unit that transmits a transmit signal in a condition where either acknowledgement or negative acknowledgement is set therein, a reception unit that receives a response signal in response to the transmission signal, a counter that counts the number of times the reception unit has not received the negative acknowledgment signal in response to the transmission signal in which the negative acknowledgement is set, and a control unit that causes the transmission unit to set the negative acknowledgement if a count value of the counter is less than a predetermined value and, if the count value is equal to or larger than the predetermined value, causes the transmission unit to set the acknowledgement.

14. A wireless communication apparatus comprising:
-
a transmission unit that transmits a transmission signal in a condition where either acknowledgement or negative acknowledgement is set therein; a reception unit that receives a positive acknowledgment signal or a negative acknowledgment signal in response to the transmission signal; a first counter that counts the number of times the reception unit has received the negative acknowledgement signal in response to the transmission signal in which the negative acknowledgement is set; a second counter that counts the number of times the reception unit has received the positive acknowledgment signal in response to the transmission signal in which the acknowledgement is set; and a control unit that causes the transmission unit to set the negative acknowledgement if a count value of the first counter is less than a first predetermined value or the count value of the second counter is a second predetermined value or larger and, if the count value of the first counter is the first predetermined value or larger and the count value of the second counter is less than the second predetermined value, causes the transmission unit to set the acknowledgement. - View Dependent Claims (15, 16, 17)

18. A wireless communication method comprising:
-
transmitting a first signal in a condition where negative acknowledgement is set as a response type therein; counting the number of times a negative acknowledgment signal has not been received in a row in response to the first signal; if the number of times has reached a predetermined value, transmitting a second signal in a condition where acknowledgement is set as the response type therein; if the positive acknowledgment signal is received in response to the second signal, transmitting a third signal in a condition where negative acknowledgement is set as the response type therein; and if the positive acknowledgment signal is not received in response to the second signal, retransmitting the second signal in a condition where acknowledgement is set as the response type therein.
