• MIMO Prime adjusts the VAM phase to achieve optimized performance for each cell in every period.
• One signal is split into two singles through VAM. The quality of received signal could be very bad due to negative superposition of two received signals.
• Based on the CQI of received signals in each cell, the VAM phase is automatically adjusted to improve the UE received signal quality.
