This page describes the 5G QoS identifier (5QI) values and their meanings. The 5QI table provides a mapping between 5QI values and various QoS parameters.

Introduction

A QoS identifier is a scalar value used in 5G NR (New Radio) as a reference to a specific QoS forwarding behavior. The different parameters, such as packet error rate and packet delay budget, are provided to a QoS flow. It is implemented in the access network by a 5QI referencing node.

A QoS flow can be either “GBR” (Guaranteed Bit Rate) or “Non-GBR” based on its QoS profile. The QoS profile of the QoS flow is transmitted to the RAN (Radio Access Network).

Each QoS flow uses a QoS profile with the following QoS parameters:

  • 5QI (5G QoS Identifier)
  • ARP (Allocation and Retention Priority)

Each non-GBR QoS flow also includes the RQA (Reflective QoS Attribute) parameter. Each GBR QoS flow also includes GFBR (Guaranteed Flow Bit Rate) and MFBR (Maximum Flow Bit Rate) for UL (Uplink) and DL (Downlink).

The following QoS parameters may also be included in a GBR QoS flow:

  • Notification Control
  • Maximum Packet Loss Rate (UL and DL)
