Title:
METHOD, DEVICE, AND SYSTEM FOR TRIGGERING FEEDBACK ACKNOWLEDGEMENT TO WIRELESS DOWNLINK COMMUNICATION RESOURCE ALLOCATIONS
Document Type and Number:
WIPO Patent Application WO/2021/012250
Kind Code:
A1
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. Multiple pending acknowledgements of multiple groups of messages may be triggered and subsequently transmitted in a single acknowledgement message. The pending acknowledgements may include acknowledgements for successful receipt of both initially transmitted message and retransmitted message.
