Abstract:
Timing considerations for autonomous uplink (AUL) downlink feedback information (AUL-DFI) is disclosed. With the flexible timeline for new radio (NR) operations, signaling of the processing timeline may be used for the served user equipments (UEs) to properly interpret the acknowledgement information in the AUL-DFI. The UE receives a signal identifying a minimum processing time of the serving base station to process AUL. Using the knowledge of the minimum processing time, the UE determines which of the outstanding AUL transmissions are accurately addressed in the AUL-DFI and which are still pending. Additional signaling to the UE may instruct the UE when to implement any changes to transmission parameters also signaled via the AUL-DFI. Slots prior to the indicated change time will be transmitted using the current parameters, while slots after the indicated time will use the updated parameters from the AUL-DFI.
