1. A method for reliable data transmission and reception in digital communication, the method comprising:

  • processing data units sequentially, each of the data units including a processing index to facilitate the data units to be processed sequentially;

    processing a data unit at a time until one of pre-defined conditions is met, wherein the pre-defined conditions include that a timing parameter assigned to the data unit is timed out or an acknowledgement of the data unit is received, wherein said processing a data unit includes;

    starting the timing parameter again until a total number of retries to transmit the data unit exceeds a pre-determined value, wherein the timing parameter times out during transmission of the data unit; and

    retransmitting the data unit every time the timing parameter is started, wherein said retransmitting the data unit ends when the timing parameter reaches a life timeout value for the data unit.
