Dear Ritika,
I strogly recommend to start from GB922 SID Resource documentation:
https://www.tmforum.org/resources/standard/gb922-resource-v19-5/You can check PhysicalResource sections. Also, you can find use cases there and it is a great guide for especially physical resources.
Best regards,
Alper
