Not all of these indicator is measured for every CSI report. Depending on the situation and configuration from network, UE perform different combination of measurement. CQI (Channel Quality Indicator) PMI (Precoding Matrix Index ) RI (Rank Indicator)
Read moreWhat is CQI PMI RI in LTE?
CQI is Channel Quality Indicator. PMI stands for Pre-coding Matrix Indicator, and RI is Rank Indicator . These three values are computed on the fly in LTE systems and used to try to optimize resource allocation among the various user end devices (UEs) that are requesting service.
Read moreWhat is CQI Reporting in LTE?
CQI stands for Channel Quality Indicator . As the name implies, it is an indicator carrying the information on how good/bad the communication channel quality is. This CQI is for HSDPA. (LTE also has CQI for its own purpose).
Read moreWhat is PMI in LTE?
LTE PMI stands for Precoding Matrix Indicators . They are applicable to closed loop transmission modes: • Transmission Mode-4:Closed Loop Spatial Multiplexing.
Read moreWhat is uplink carrier aggregation?
Carrier aggregation (CA) is a special form of LTE technology . This technology is used to increase the bandwidth and bitrate and to enable high data rates for bulk traffic. At the same time, this enables the user equipment and network to use more than one carrier frequency.
