Question: In a 5G network, why is it necessary to differentiate between the statistics and measurements of Modulation and Coding Scheme (MCS) distribution for Multi-User Multiple Input Multiple Output (MU-MIMO) and Single-User Multiple Input Multiple Output (SU-MIMO)?
Option 1: Because MU-MIMO and SU-MIMO utilize different types of physical resources.
Option 2: Due to the varying impact of MCS on PDSCH and PUSCH RBs in each MIMO type.
Option 3: As a result of differing network architecture requirements for MU-MIMO and SU-MIMO.
Option 4: Because of differences in user pairing and interference management between MU-MIMO and SU-MIMO scheduling strategies.
Explanation: The correct answer highlights the key reason for differentiating MCS distribution statistics between MU-MIMO and SU-MIMO, due to unique challenges posed by user pairing and interference in each MIMO technique, impacting MCS scheduling efficiency, network performance, and service quality.
