Various methods and systems of the present disclosure provide a protocol data unit (PDU) set based quality of service (QoS) handling in a wireline access. To support the PDU Set based QoS handling in the wireline access, one or more PDU Set QoS parameters and / or PDU Set information may be provided to one or more wireline nodes (e.g., a wireline gateway access function (W-AGF) and / or a residential gateway (RG) etc.). When the W-AGF receives one or more N2 requests associated with one or more PDU session resources, the W-AGF maps one or more QoS profiles received from 5G core (5GC) to a wireline access user plane (W-UP) QoS level. The W-AGF sets up one or more W-UP resources based on the W-UP QoS level for a PDU session. Further, various methods and systems of the present disclosure also provide low latency, low loss, and scalable throughput (L4S) enabled wireline access.
