Abstract

A communication apparatus that performs receiving processing of data transmitted at timings of a predetermined interval, the communication apparatus having a transmitting unit configured to transmit a signal indicating that a data is successfully received when the data transmitted at M th timing according to the predetermined interval is successfully received and a control unit configured to perform a control for providing a period in which other receiving processing different from the receiving processing is at least performed or a receiving process is not performed until when next M+1 th timing comes according to the predetermined interval after the transmission of the signal.

Claims (20)

1. A communication apparatus comprising:

a receiver configured to perform receiving processing of data transmitted at timings according to a given interval;

a transmitter configured to transmit a signal indicating that data is successfully received when the data transmitted at M th timing according to the given interval is successfully received by the receiver; and

a controller configured to perform a control for providing a period in which other receiving processing different from the receiving processing is at least performed between a transmission timing of the signal and next M+1 th timing according to the given interval, the other receiving processing being a receiving processing of data transmitted from a first communication apparatus different from a second communication apparatus in communication with the communication apparatus or to perform a control for providing a period in which a receiving process of data transmitted for the communication apparatus is not performed between the transmission timing of the signal and the next M+1 th timing.

2. A communication apparatus comprising:

a receiver configured to perform receiving processing of data transmitted at timings according to a given interval;

a transmitter configured to transmit a signal indicating that data is not successfully received when the data transmitted at M th timing according to the given interval is not successfully received by the receiver; and

a controller configured to perform, when it is detected that retransmission control processing is not performed in response to the transmission of the signal, a control for providing a period in which other receiving processing different from the receiving processing is at least performed between a detection timing of not performed retransmission control processing and next M+1 th timing according to the given interval, the other receiving processing being a receiving processing of data transmitted from a first communication apparatus different from a second communication apparatus in communication with the communication apparatus or to perform a control for providing a period in which a receiving process of data transmitted for the communication apparatus is not performed between the detection timing and the next M+1 th timing.

3. A communication apparatus comprising:

a controller configured to perform a retransmission of data to another communication apparatus in communication with the communication apparatus when a response to new data is not received from the another communication apparatus and when a signal indicating that the data is not successfully received by the another communication apparatus is received, wherein the controller does not perform an N+1 th retransmission when a response to the N th retransmission is not received from the another communication apparatus, but performs an N+1 th retransmission when a response indicating that the N th retransmission is not successfully received by the another communication apparatus is received.

4. A receiving method of a communication apparatus comprising:

performing receiving processing of data transmitted at timings according to a given interval;

transmitting a signal indicating that data is successfully received when the data transmitted at M th timing according to the given interval is successfully received by the receiver; and

performing a control for providing a period in which other receiving processing different from the receiving processing is at least performed between a transmission timing of the signal and next M+1 th timing according to the given interval, the other receiving processing being a receiving processing of data transmitted from a first communication apparatus different from a second communication apparatus in communication with the communication apparatus or to perform a control for providing a period in which a receiving process of data transmitted for the communication apparatus is not performed between the transmission timing of the signal and the next M+1 th timing.

5. A receiving method of a communication apparatus comprising:

performing receiving processing of data transmitted at timings according to a given interval;

transmitting a signal indicating that data is not successfully received when the data transmitted at M th timing according to the given interval is not successfully received; and

performing, when it is detected that retransmission control processing is not performed in response to the transmission of the signal, a control for providing a period in which other receiving processing different from the receiving processing is at least performed between a detection timing of not performed retransmission control processing and next M+1 th timing according to the given interval, the other receiving processing being a receiving processing of data transmitted from a first communication apparatus different from a second communication apparatus in communication with the communication apparatus or to perform a control for providing a period in which a receiving process of data transmitted for the communication apparatus is not performed between the detection timing and the next M+1 th timing.

6. A transmitting method comprising:

performing a retransmission of data to another communication apparatus in communication with the communication apparatus when a response to new data is not received from the another communication apparatus and when a signal indicating that the data is not successfully received by the another communication apparatus is received, and not performing an N+1 th retransmission when a response to an N th retransmission is not received from the another communication apparatus, but performs the N+1 th retransmission when a response to the N th retransmission is not successfully received by the another communication apparatus is received.
