Communication apparatus and communication method

A communication apparatus, comprising:

• communication circuitry configured to perform wireless communication;
• and
• control circuitry configured to control, in response to a reply to a transmission of data from the communication apparatus to another apparatus, such that at least a subset of a plurality of one-encoding units in a predetermined transmission unit is re-transmitted to the another apparatus,
• wherein the control circuitry:
• controls such that information for allowing the another apparatus to specify the plurality of one-encoding units to be made a target of re-transmission is notified to the another apparatus,
• performs, based on information regarding the plurality of one-encoding units to be made the target of re-transmission, a predetermined process for predetermined information associated with the plurality of one-encoding units, and
• controls such that the predetermined information for which the predetermined process is carried out is notified, as the information for specifying the plurality of one-encoding units, to the another apparatus units in the predetermined transmission unit not successfully received at the another apparatus;
• and
• based on quasi-static information notified to the another apparatus, controlling, in response to a reply from the another apparatus to the transmission of data to the another apparatus, such that, upon the another apparatus failing to successfully receive only a subset of the plurality of one-encoding units in the predetermined transmission unit, either:
• a) only the subset of the plurality of one-encoding units in the predetermined transmission unit that the another apparatus fails to receive are re-transmitted to the another apparatus or b) all of the plurality of one-encoding units included in the predetermined transmission unit are re-transmitted to the another apparatus.

A communication method performed by a communication apparatus, comprising:

• performing wireless communication;
• controlling such that information corresponding to a plurality of one-encoding units, in a predetermined transmission unit, to be made a target of re-transmission is notified to the another apparatus, the target of re-transmission being any of the plurality of one-encoding
• wherein information for allowing the another apparatus to specify the plurality of one-encoding units to be made a target of re-transmission is controlled so as to be notified to the another apparatus;
• performing, based on information regarding the plurality of one-encoding units to be made the target of re-transmission, a predetermined process for predetermined information associated with the plurality of one-encoding units;
• and
• controlling such that the predetermined information for which the predetermined process is carried out is notified, as the information for specifying the plurality of one-encoding units, to the another apparatus.

A non-transitory computer-readable program product containing instructions to cause a computer to perform a communication method, the communication method comprising:

• performing wireless communication;
• controlling such that information corresponding to a plurality of one-encoding units, in a predetermined transmission unit, to be made a target of re-transmission is notified to the another apparatus, the target of re-transmission being any of the plurality of one-encoding units in the predetermined transmission unit not successfully received at the another apparatus;
• and
• based on quasi-static information notified to the another apparatus:
• controlling, in response to a reply from the another apparatus to the transmission of data to the another apparatus, such that, upon the another apparatus failing to successfully receive only a subset the plurality of one-encoding units in the predetermined transmission unit, either:
• a) only the subset of the plurality of one-encoding units in the predetermined transmission unit that the another apparatus fails to receive are re-transmitted to the another apparatus or b) all of the plurality of one-encoding units included in the predetermined transmission unit are re-transmitted to the another apparatus.
