1. A method of operating a wireless data network that uses Hybrid Automatic Repeat Request (HARQ) to serve wireless User Equipment (UEs) that execute server applications, the method comprising:
Distributed Unit (DU) circuitry executing an Uplink (UL) DU Media Access Control (MAC) that comprises an UL DU HARQ and the UL DU MAC receiving UL server data from the server applications in the wireless UEs, processing the UL server data with the UL DU HARQ, generating UL HARQ Acknowledgements (ACKs) based on the UL server data, and transferring the UL server data for delivery to Central Unit (CU) circuitry;
the CU circuitry executing an UL CU MAC and the UL CU MAC receiving the UL server data, processing the UL server data, and transferring the UL server data;
the CU circuitry receiving Downlink (DL) server data for the server applications in the wireless UEs and transferring the DL server data to the DU circuitry; and
the DU circuitry executing a DL DU MAC that comprises a DL DU HARQ, and the DL DU MAC receiving the DL server data for the server applications from the CU circuitry, processing the DL server data with the DL DU HARQ, and transferring the DL server data and the UL HARQ ACKs for delivery to the wireless UEs.
