Abstract
The present disclosure describes methods and apparatus for real-time physical layer processing in distributed units (DU). A downlink data processing method includes receiving a downlink transport block at the physical layer and generating a plurality of sub-transport blocks mapped to a plurality of symbols by processing the received transport block. The method further includes processing the plurality of sub-transport blocks sequentially using at least one transfer function to generate the plurality of symbols which are then transmitted to a radio unit (RU) for transmission to a user equipment (UE). An uplink data processing method includes generating an uplink transport block by processing a plurality of symbols received at the DU from the RU. The plurality of symbols are processed using at least one uplink transfer function. A downlink/uplink transfer function is functionally equivalent to a plurality of downlink/uplink sequential signal processing modules.
