5g qci table
5G, the QCI table is expanded compared to 4G, reflecting the more diverse requirements and services that 5G aims to support. Here's a technical breakdown of the 5G QCI table:
5G QCI Table:
| QCI | Allocation & Packet Delay Budget (ms) | Packet Error Loss Rate | Example Services or Use Cases |
|---|---|---|---|
| 1 | 16ms, 1e-2 | 10^-2 | Conversational Voice |
| 2 | 32ms, 1e-3 | 10^-3 | Conversational Video |
| 3 | 32ms, 1e-3 | 10^-3 | Real-Time Gaming |
| 4 | 64ms, 1e-6 | 10^-6 | Non-Critical Services |
| 5 | 125ms, 1e-6 | 10^-6 | Internet |
| 6 | 125ms, 1e-6 | 10^-6 | Machine-Type Communication |
| 7 | 125ms, 1e-6 | 10^-6 | Machine-Type Communication |
| 8 | 300ms, 1e-6 | 10^-6 | Mission Critical Applications |
| 9 | - | 10^-2 | Mission Critical Data |
| 65-69 | Reserved for future use | - | - |
Key Parameters Explained:
- Allocation & Packet Delay Budget (ms): This specifies the maximum allowable delay for a packet to be transmitted end-to-end. Different services have varying tolerance levels for latency, so the QCI helps to ensure the network meets these requirements.
- Packet Error Loss Rate: This defines the acceptable rate of packet loss. For real-time services like voice or video, even a small packet loss can significantly degrade the user experience.
- Example Services or Use Cases: This column provides a high-level description of the type of services or applications that might utilize each QCI value. For instance, QCI 1 is suitable for conversational voice services where low latency is crucial.
Summary:
- QCIs 1-3: These are generally used for ultra-reliable low-latency communication (URLLC) services, which require minimal delay and are highly reliable.
- QCIs 4-5: These are for enhanced Mobile Broadband (eMBB) services, which prioritize high data rates and are less sensitive to latency but still require reliable data transmission.
- QCIs 6-9: These are for massive Machine-Type Communications (mMTC) services, catering to the needs of IoT devices and applications where scalability and long battery life are essential.
