📋 LAB Configuration Guideline

1. How to configure:
- Select a mode (TM, UM, AM) and direction (Tx/Rx).
- Choose a logical channel; the appropriate mode is indicated.
- For UM/AM, toggle header visibility and segmentation.
- Parameters adjust the visual representation.

2. What will be the flow:
- The diagram shows the RLC entity with PDCP above and MAC below.
- For TM, no header, direct passthrough.
- For UM, a header is added; segmentation can be applied.
- For AM, the header includes sequence numbers, and a retransmission buffer appears.

3. What student can expect:
- Understand the three RLC modes and their characteristics.
- See how headers differ between modes.
- Observe the role of segmentation and retransmission.

4. Recommended exploration:
- Start with TM, then UM, then AM – compare header presence and complexity.
- Enable segmentation in UM/AM to see how SDU is split.
