  • Publication number: 20220150030
    Abstract: This disclosure describes implementations of a modified ARQ/HARQ procedure that deviates from normal wait-and-stop ARQ/HARQ procedure. In particular, a series of messages to be transmitted may be organized in a predetermined number of message groups. By using various control parameters communicated between the transmitting device and the receiving device, the different groups of messages may be independently transmitted without having the transmission of one group of messages wait for acknowledgement of another group of messages. In addition, within each of the message groups, the receiving device is allowed to store and hold acknowledgement of messages until a later time specified through control parameters transmitted via control messages. A control message may trigger transmission of stored acknowledgement for one or more message groups identified, again, by control parameters included in the control message.
