Question: In 5G New Radio (NR), how are Virtual Resource Blocks (VRBs) mapped to Physical Resource Blocks (PRBs) in the context of resource allocation?
Option 1: Non-interleaved mapping, where each VRB is directly mapped to a specific PRB.
Option 2: Interleaved mapping, where VRBs are distributed across multiple PRBs for diversity gain.
Option 3: Dynamic mapping, which switches between interleaved and non-interleaved based on channel conditions.
Option 4: Random mapping, where VRBs are randomly assigned to available PRBs.
Explanation: In the context of 5G NR resource allocation, non-interleaved mapping is utilized for Virtual Resource Blocks (VRBs) to Physical Resource Blocks (PRBs) conversion. This approach ensures a straightforward, one-to-one correspondence between VRBs and PRBs, simplifying resource management and allocation processes in the network. This method is particularly beneficial for maintaining contiguous resource block allocations, which can be advantageous for certain types of traffic or service requirements.
