Question: In 3GPP Terminal conformance specification for Radio transmission and reception (TDD), when the specified Error Rate (ER) is 10%, which statistical distribution is **not** recommended due to its unavailability in standard mathematical tools, despite offering optimal results?
Option 1: Poisson Distribution
Option 2: Chi Square Distribution
Option 3: Normal Distribution
Option 4: Binomial Distribution
Explanation: The binomial distribution is mentioned as the optimal choice for describing RRM delay statistics when the specified ER is 10%. However, it's noted that the inverse cumulative operation for the binomial distribution is not supported by standard mathematical tools, making it impractical to use despite its optimality. In contrast, Poisson and Chi Square Distributions are considered but with caveats of providing sub-optimal results in certain scenarios.
