1. A method performed by a wireless communication module in a distributed unit (DU), the method comprising:
scheduling data of at least one data radio bearer (DRB) at a first layer implemented at the DU;
performing a mapping between a plurality of uplink (UL) or downlink (DL) Quality of Service (QOS) flow packets and the at least one DRB at a mapping layer that is the first layer or a second layer, implemented at the DU, immediately above the first layer;
marking, at the mapping layer, a QoS flow ID (QFI) for each DL and UL QoS flow packet;
obtaining, at the first layer, QoS attribute information of each QoS flow mapped to the at least one DRB, wherein the data of the at least one DRB is scheduled based on the QoS attribute information, wherein the QoS attribute information comprises at least one of: an aggregated DRB QoS profile, a QoS flow profile, or a QoS requirement of each QoS flow mapped to the at least one DRB;
obtaining, at the mapping layer, a mapping rule from a control plane for the mapping between the plurality of QoS flows and the at least one DRB, wherein the mapping is performed based on the mapping rule; and
processing data at a layer above the second layer with a granularity of at least one of: a QoS flow or a protocol data unit (PDU) session.
