با توجه به گزینه mimo mode
نظرتون درباره این مطلب چیه؟ من اینطور فهمیدم که شما به خاطر سیگنال ضعیف نتوستید از حالت میمو به شکل کامل استفاده کنید.
MIMO Mode is for some reason always TBD, and Rank Indicator can be either 1 or 2.
RI=1 indicates that only 1 data stream is sent (plus a copy) from the eNB, meaning your device isn't utilizing MIMO for spatial multiplexing and instead is in Receive Diversity mode. This happens when SINR is low and improved signal robustness is needed.
RI=2 indicates that signal is robust enough, SINR is high enough (typically over 15dB), so 2x2 MIMO capable eNB is scheduling 2 separate data streams to your device, which means MIMO is utilized for improved data rates.
