Question: What are the power saving resource allocation methods supported by a SL UE in Mode 2?
Option 1: Only full sensing-based resource allocation
Option 2: Partial sensing-based resource allocation and random resource selection
Option 3: Random resource selection only
Option 4: Full sensing-based resource allocation and periodic resource reservation
Explanation: A SL UE in Mode 2 supports partial sensing-based resource allocation and random resource selection as power saving resource allocation methods, allowing for more efficient use of resources.
