Receiving apparatus, receiving method, and non-transitory computer readable storage medium

A receiving method performed by a receiving apparatus that receives a signal from a predetermined transmitter, the receiving method comprising:

• first splitting a received signal received from the transmitter into a predetermined size;
• retaining split signals obtained at the first splitting in a split signal storing unit;
• performing error checking on each of the split signals stored in the split signal storing unit and retaining a result of the error checking in a check result storing unit;
• sending a request, when an error is contained in a coupled signal obtained by coupling the split signals stored in the split signal storing unit, to the transmitter to retransmit the received signal;
• second splitting, when a retransmission signal associated with the received signal is received, the retransmission signal into a predetermined size;
• combining a split signal stored in the split signal storing unit and a split signal split at the second splitting;
• and
• controlling, among the split signals stored in the split signal storing unit, not to update the split signal for which an error checking result does not indicate an error and controlling to update the split signal for which an error checking result indicates an error to a combined signal combined at the combining.

A non-transitory computer readable storage medium having stored therein a reception control program for controlling a receiving apparatus that receives a signal from a predetermined transmitter, the reception control program causing a computer to execute a process comprising:

• splitting a received signal received from the transmitter into a predetermined size;
• retaining split signals obtained at the splitting in a split signal storing unit;
• performing error checking on each of the split signals stored in the split signal storing unit and retaining a result of the error checking in a check result storing unit;
• combining, when a retransmission signal is received, a split signal obtained by splitting the retransmission signal at the splitting and a split signal stored in the split signal storing unit;
• controlling, among the split signals stored in the split signal storing unit, not to update the split signal for which an error checking result does not indicate an error and controlling to update the split signal for which an error checking result indicates an error to a combined signal combined at the combining;
• and
• sending, when an error is contained in a split signal stored in the split signal storing unit, a request to the transmitter to retransmit the retransmission signal.

A receiving apparatus comprising:

• a processor;
• and
• a memory, wherein the processor executes a process comprising:
• splitting a received signal received from the transmitter into a predetermined size;
• retaining split signals obtained at the splitting in a split signal storing unit;
• performing error checking on each of the split signals stored in the split signal storing unit and retaining a result of the error checking in a check result storing unit;
• combining, when a retransmission signal is received, a split signal obtained by splitting the retransmission signal at the splitting and a split signal stored in the split signal storing unit;
• controlling, among the split signals stored in the split signal storing unit, not to update the split signal for which an error checking result does not indicate an error and controlling to update the split signal for which an error checking result indicates an error to a combined signal combined at the combining;
• and
• sending, when an error is contained in a split signal stored in the split signal storing unit, a request to the transmitter to retransmit the retransmission signal.
