Enhanced performance hybrid-arq

A method comprising:

• identifying, by a transmitting device, a first subset of information bits from a set of information bits to be transmitted;
• selecting, by the transmitting device, a first vector based on the first subset of information bits, wherein the first vector has a series of elements;
• transmitting, by the transmitting device, a first element of the first vector;
• receiving a negative acknowledgment (NACK) in response to transmitting the first element of the first vector;
• and
• in response to receiving the NACK, transmitting, by the transmitting device, a second element of the first vector.

A communication device comprising processing circuitry configured to:

• receive an element of a vector, wherein the vector is selected based on a subset of information bits from a set of information bits, wherein the vector has a series of elements;
• attempt to decode the vector based on the received element, wherein the subset of information bits comprises an index of the vector in a code book;
• in an instance in which the communication device is unable to decode the vector,
• transmit a NACK, and
• receive a subsequent element of the vector;
• and
• in an instance in which the communication device is able to decode the vector, transmit an ACK.
