Hi All.

What are the probable issues for a UE latched to 5G with no throughput?

There are several possible issues for a UE latched to 5G with no throughput. Some of them are:

  • The UE may not have a valid subscription or authentication for 5G services.
  • The UE may not support the 5G NR features or configurations required by the network, such as bandwidth, SCS, frequency range, MIMO layers, etc.
  • The UE may have poor radio conditions or interference that affect the SINR and channel quality.
  • The UE may have hardware or software problems that prevent it from receiving or transmitting data on the 5G NR interface.
  • The network may have congestion or misconfiguration that limit the resources or scheduling for the UE.

To troubleshoot these issues, you can use some tools such as Real 5G UE measurements or Limitation of 5G Maximum Throughput for a UE to analyze the parameters and performance of the UE and the network.
You can also refer to the Study on 5G NR User Equipment (UE) application layer data throughput performance for more details on the factors affecting the 5G NR throughput.
