An exemplary method includes determining, at a centralized processing apparatus of a wireless network, a first subset of downlink user plane data corresponding to one or more wireless user equipments at least by calculating input data required at each of one or more L1 PHY processing stages of a remote processing apparatus, wherein the first subset includes bits required by a remote processing apparatus to select a first symbol for transmission to the one or more user equipments at a first time slot; and streaming, via a fronthaul interface, the bits of the first subset followed by bits of one or more further subset of downlink user plane data, wherein the bits of the further subset of user plane data includes only the bits required to select by the remote processing apparatus a next symbol for transmission to the one or more of the wireless user equipments at a next time slot immediately following the first time slot.
