LTE physical layer comparison to HSPA. LTE builds on the learning of several WCDMA/HSPA Releases and covers from the start HARQ, BTS scheduling and adaptive coding and modulation (+ multiple antenna TX/RX with MIMO). LTE eNodeB is similar to Base station of other technologies such as WCDMA, GSM etc. eNodeB Physical layer consists of Channel… Read More »

CQI,PMI and RI – LTE Quality Indicators

By | July 17, 2017

LTE stands for fast and reliable data transmission. Accurately measuring the channel quality with the user equipment plays a major role. We have listed out three LTE Quality Indicators that serves as a benchmark for transmission quality in the downlink. CQI (Channel Quality Indicator) PMI (Precoding Matrix Indicator) RI (Rank Indicator) The User Equipment (UE) can measure all three and… Read More »
