📋 LAB Configuration Guideline

1. How to navigate:
- Click any CE button on the left to select it.
- The main panel shows the CE name, LCID, direction, size, and purpose.
- A visual diagram of the MAC subheader and CE payload is drawn below.
- For structured CEs (e.g., BSR, PHR), a bit‑level diagram appears.

2. What student can expect:
- The subheader (purple) always contains LCID; some CEs have additional fields.
- The payload (yellow) may contain multiple octets; fields are labelled when possible.
- eLCID note explains that extended LCIDs allow more CEs beyond LCID 63.

3. Recommended exploration:
- Start with Short BSR (UL, LCID 61) to see a simple one‑octet CE.
- Then try C‑RNTI (UL, LCID 58) for a two‑octet CE.
- Compare with Long BSR (UL, LCID 62) which has variable size.
- Finally, look at DL CEs like SCell Activation (LCID 58) to see bitmaps.
