Abstract: The present disclosure describes techniques of data transmission over a fronthaul network in a system comprising a baseband unit (BBU) and a plurality of radio units (RUs) communicatively coupled with the BBU over the fronthaul network. In the techniques of the present disclosure, the system generates a plurality of downlink commands corresponding to the plurality of RUs for scheduling a plurality of UEs across the plurality of RUs, where generating the plurality of downlink commands comprises generating a single downlink command per RU of the plurality of RUs. The system transmits the downlink commands towards the plurality of RUs over the fronthaul network and receives a plurality of uplink data packets corresponding to the plurality of downlink commands over the fronthaul network, where receiving the plurality of uplink data packets comprises receiving a single uplink data packet per RU comprising data associated with all UEs served by the RU.

Abstract: A fronthaul unit for use in a distributed antenna system includes at least one hardware buffer configured to: receive first uplink packets at a first numerology for a first carrier from at least a first remote unit associated with a first donor unit, wherein first symbols of the first uplink packets for the first carrier are received at a first symbol timing; receive second uplink packets at a second numerology from a second carrier from at least a second remote unit associated with a second donor unit, wherein second symbols of the second uplink packets for the second carrier are received at a second symbol timing, wherein the second symbol timing is a multiple of the first symbol timing; and poll both the first uplink packets and the second uplink packets from the at least one hardware buffer at a highest granularity symbol notion based on the first symbol timing.
