Method for communicating data using a modified SR-ARQ protocol

A method comprising the steps of:

• A) providing data to be transmitted;
• B) automatically parsing the data into messages and fixed-length blocks, which messages are comprised of the blocks and which messages are no longer than a predetermined length;
• C) buffering the messages pending transmission;
• D) transmitting the messages;
• E) upon receipt of a message-received communication as corresponds to a particular buffered message, unbuffering the particular buffered message;
• F) upon receipt of a message-partially-received communication as corresponds to a particular buffered message, retransmitting
• i) at least some of those blocks that correspond to portions of the particular buffered message that were not adequately received;
• ii) at least one but not all of those blocks that correspond to portions of the particular buffered message that were adequately received.

A method comprising the steps of:

• at a first data unit:
• A) providing data to be transmitted;
• B) automatically parsing the data into messages and fixed-length blocks, which messages are comprised of the blocks and which messages are no longer than a predetermined length;
• C) error detection coding the blocks to provide error detection coded messages;
• D) buffering the error detection coded messages pending transmission;
• E) transmitting the error detection coded messages;
• at a second data unit:
• F) receiving the error detection coded messages to provide received messages;
• G) processing the error detection coded messages to detect the presence of errors in any blocks that comprise the received messages;
• H) when no errors at detected, transmitting a message-received communication;
• I) when errors are detected in at least one block, transmitting a message-partially-received communication;
• at the first data unit:
• J) upon receipt of a message-received communication as corresponds to a particular buffered message, unbuffering the particular buffered message;
• K) upon receipt of a message-partially-received communication as corresponds to a particular buffered message, retransmitting:
• i) at least some blocks that correspond to portions of the particular buffered message that were not adequately received;
• ii) but none of those blocks that correspond to portions of the particular buffered message that were adequately received.

A method for reliably communicating data from a first data unit to a second data unit using a wireless communication resource, comprising the steps of:

• A) providing data to be transmitted;
• B) automatically parsing the data into messages and fixed-length blocks, which messages are comprised of the blocks and which messages are no longer than a predetermined length, such that messages of substantially different lengths will be comprised of different numbers of blocks;
• C) error detection coding the blocks to provide error detection coded messages;
• D) buffering the error detection coded messages pending transmission;
• E) transmitting the error detection coded messages to the second data unit using the wireless communication resource;
• F) upon receipt of a message-received communication from the second data unit as corresponds to a particular buffered error detection coded message, unbuffering the particular buffered error detection coded message, thereby establishing capacity to allow buffering of another message;
• G) upon receipt of a message-partially-received communication from the second data unit as corresponds to a particular buffered error detection coded message, retransmitting:
• i) at least some blocks that correspond to portions of the particular buffered error detection coded message that were not adequately received;
• ii) but none of those blocks that correspond to portions of the particular buffered error detection coded message that were adequately received.
