Method for communicating data using a modified SR-ARQ protocol

Claim 1

A method comprising the steps of: A) providing data robe 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 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.

Claim 2

A method comprising the steps of: A) providing data robe 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 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.

Claim 9

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.

Claim 10

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.

Claim 17

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.

Claim 18

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.

Claim 25

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.

Claim 26

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.
