📋 LAB Configuration Guideline

1. How to configure:
- Select a logical channel from the dropdown (BCCH, PCCH, CCCH, DCCH, DTCH).
- Choose direction: Downlink (DL) or Uplink (UL).
- The display shows the mapping to the appropriate transport channel (DL‑SCH, UL‑SCH, or RACH).

2. What will be the flow:
- The diagram illustrates the RLC, MAC, and PHY layers.
- Arrows indicate the flow of data from logical to transport channels.
- The mapping text updates in real time.

3. What student can expect:
- Understand the relationship between logical channels (from RLC) and transport channels (to PHY).
- See which logical channels are used in downlink vs uplink.
- Note that CCCH in uplink can be mapped to either UL‑SCH or RACH.

4. Recommended exploration:
- Try each logical channel in both directions and observe the mapping.
