US 2022/0029751 A1 · DYNAMIC WIRELESS NETWORK ARCHITECTURE TO SERVE UPLINK-CENTRIC AND DOWNLINK-CENTRIC USER APPLICATIONS

Abstract

In a wireless data network, a Distributed Unit (DU) receives Uplink (UL) server data from server applications in wireless User Equipment (UEs). The DU processes the UL server data with an UL DU Hybrid Automatic Repeat Request (HARQ), generates UL HARQ Acknowledgements (ACKs) based on the UL server data, and transfers the UL server data to a Central Unit (CU). The CU receives the UL server data, processes the UL server data with an UL CU MAC, and transfers the UL server data. The CU receives (Downlink) DL server data for the server applications in the wireless UEs and transfers the DL server data to the DU. The DU receives the DL server data from the CU, processes the DL server data with a DL DU MAC comprising a DL DU HARQ, and transfers the DL server data and the UL HARQ ACKs to the wireless UEs.
