Certain embodiments of the present disclosure propose techniques for improving automatic repeat request (ARQ) feedback messages to reduce unnecessary transmissions by notifying the transmitter of the last acknowledged block in the ARQ feedback message.

Methods and systems for ARQ feedback message improvement

Embodiments of the present disclosure allow a HARQ transmitter to provide a receiver an indication of the protocol data units (PDUs) that should not be expected because they are part of a data burst that has been retransmitted a maximum allowable number of times. The indication message may contain a maximum serial number contained in the data burst that has reached the maximum number of retransmissions, or the serial number of a first PDU in the next data burst.

Methods and systems using window start update for wireless communication HARQ connection

Systems and methods for handling automatic repeat request (ARQ) resets are described. A first device may receive a message initiating an ARQ reset procedure transmitted by a second device. The first device may determine if both the first and second devices have initiated an ARQ reset procedure. The first device may take action to limit a loss of blocks of data exchanged between the first and second devices, if both the first and second devices have initiated an ARQ reset procedure.
