BSIC The Base Station Identity Code (BSIC), which is a code used in GSM to uniquely identify a base
station.
This parameter is for GPRS only. The value is ‘0(zero) if the Current Access Technology is not
GPRS. The value is ‘N/A’ if there is no network connection.
SINR This displays the Signal to Interference plus Noise Ratio (SINR) in dB. This is also a measure of signal
quality and used by the UE (User Equipment) to calculate the Channel Quality Indicator (CQI)
that it reports to the network. A negative value means more noise than signal.
CQI This displays the Channel Quality Indicator (CQI). It is an indicator carrying the information on
how good/bad the communication channel quality is.
MCS MCS stands for modulation coding scheme. The base station selects MCS based on current
radio conditions. The higher the MCS the more bits can be transmitted per time unit.
RI This displays the Rank Indication, one of the control information that a UE will report to eNodeB
(Evolved Node-B) on either PUCCH (Physical Uplink Control Channel) or PUSCH (Physical Uplink
Shared Channel) based on uplink scheduling.
PMI This displays the Precoding Matrix Indicator (PMI).
PMI is for transmission modes 4 (closed loop spatial multiplexing), 5 (multi-user MIMO), and 6
(closed loop spatial multiplexing using a single layer).
PMI determines how cellular data are encoded for the antennas to improve downlink rate.
