What kind of statistics does AODT provide?

Hello,

I am looking for the list of statistics provided by AODT for both BS and UE side.
For example, number of used PRBs…
I haven’t installed AODT yet, but I need these information to clarify my sceanario.
Is there any document desribes full list of statistics?

Thank you in advance.

You can find the clickhouse database format here:
https://docs.nvidia.com/aerial/aerial-dt/text/additional_info.html#database-tables
And you can find some parameters about RAN Sim here:
https://docs.nvidia.com/aerial/aerial-dt/text/ran_digital_twin.html#local-console

@yjun.park As @junxian mentioned, you can see the statistics and the data provided in the documentation posted above. Essentially:

  1. Complex channel coefficients in both frequency and time domain, for every Tx-Rx link for every UE-RU link
    2.Full mobility model: trajectory of each UE including heading and other information
  2. If RAN is enabled , then the details of MAC and PHY KPIs (see the telemetry table)
  3. Additionally, the entire simulation scenario including antenna antenna patterns are available for post processing.

Hi @kpasad1,

Is it possible to collect additional statistics from AODT, such as RSRP, RSRQ, or SINR for simulated UEs? I believe these variables are calculated in cuPHY and cuMAC, but currently, we cannot directly retrieve them from the ClickHouse database.

If ClickHouse does not support these variables, would it be possible to find them in the AODT logs instead?

Thank you for your help!

@junxian In the RAN mode, the following are available:

  1. Pre-equalization SINR on the DMRS RBs
  2. Post -equalization SINR on the PUSCH RBs

Both of this are available in the telemetry database.

Thank you!

Hello, @kpasad1. In the AODT document, I can not find the SINR in the telemetry table. The table infomation are listed as followed:

Could you give me more information about it?

We try to use Clickhouse client to collect the info from telemetry, but still cannot find the SINR values. The log is shown as following:

We found the SINR in the results of the local console of RAN Digital Twin, as following: RAN Digital Twin - NVIDIA Docs

However, we cannot find those information in the Clickhouse. Could you tell us how to collect those infomation?

@junxian Sorry, my mistake. In AODT 1.1, the SINR values are not logged into the database. The values will be available via the database in AODT 1.2. In the meantime, you have to use the values from the console
