1. A method for control of automatic repeat requests between a transmitting terminal and a receiving terminal comprising:

  • defining a buffer window of a buffer at a communication device, the buffer window to buffer multiple higher layer data blocks, each higher layer data block segmented into multiple physical layer data blocks, the buffer window beginning at a current higher layer data block in which at least one physical layer data block has not been received;

    obtaining an indication of whether physical layer data blocks are completely received at the receiving terminal;

    determining, based on the obtaining step, that a subsequent higher layer data block within the buffer window has been completely received; and

    discarding the current higher layer data block when a time delay of the current higher layer data block exceeds an estimate of a delay tolerance corresponding to a higher layer application.
