Question: In 3GPP Terminal Conformance Specification for Radio Transmission and Reception (FDD), when evaluating RRM delay statistics with a specified Error Rate (ER) of 10%, which distribution is **not** recommended due to its unavailability in standard mathematical tools, despite potentially offering optimal results?
Option 1: Poisson Distribution
Option 2: Binomial Distribution
Option 3: Chi Square Distribution
Option 4: Normal Distribution
Explanation: The binomial distribution is mentioned as the one that could achieve optimal results for describing RRM delay statistics with a specified ER of 10%. However, it's noted that the inverse cumulative operation for this distribution is not supported by standard mathematical tools, making it impractical to use despite its potential optimality. In contrast, Poisson and Chi Square Distributions are discussed as alternatives, albeit with sub-optimal results in certain contexts. The Normal Distribution is not mentioned in relation to this specific scenario.
