Which of the following statements about the global tuning algorithm is correct? (Multiple choice)

Question

Options

• AThe core of the dynamic channel adjustment algorithm is an iterative exhaustive algorithm, which
• BThe goal of the TPC algorithm is to select an appropriate transmit power to meet the coverage
• CThe minimum interference threshold means that the interference to neighbors is very low and the
• DIf the neighbor's interference is less than the minimum interference threshold, decide whether to

• A
  73% (33)
• B
  18% (8)
• D
  9% (4)

Explanation

Options A and C are correct because the dynamic channel adjustment (DCA) algorithm fundamentally works by iteratively exhausting possible channel combinations to evaluate interference impact - this iterative exhaustive approach is its defining characteristic. Similarly, the minimum interference threshold is correctly understood as the floor below which neighbor interference is considered acceptably low, making that assignment potentially favorable.

Option B is incorrect because TPC (Transmit Power Control) is not primarily about coverage - its goal is to use the minimum transmit power needed to maintain link quality, thereby reducing interference to neighboring cells. Framing it as a "coverage" goal misrepresents its interference-management purpose.

Option D is incorrect because it describes the wrong conditional logic: when neighbor interference falls below the minimum threshold, no corrective action is needed - that's already an acceptable state. The algorithm should trigger decisions when interference exceeds a threshold, not when it's already low.

Memory tip: Think of the two correct answers as describing method (A = how DCA works: exhaustive iteration) and meaning (C = what the minimum threshold actually defines). The distractors flip the purpose of TPC and reverse the threshold logic - watch for answers that swap "coverage" for "interference control" or invert threshold conditions (less than vs. greater than).
