If the UE can reliably detect that R1 is available it may use R1 in addition to R0 to determine RSRP. For RSRP determination the cell-specific reference signals R0 according TS 36.211 shall be used. Reference signal received power (RSRP), is defined as the linear average over the power contributions (in ) of the resource elements that carry cell-specific reference signals within the considered measurement frequency bandwidth. The formal definition of RSRP in 3GPP 36.214 is as follows : You can think of this as the one similar to CPICH RSCP in WCDMA.
This is the most important item UE has to measure for cell selection, reselection and handover. Reliable data speeds may be attained, but marginal data with drop-outs is possible.RSRP is the linear average of reference singal power (in Watts) accorss the specified bandwidth (in number of REs). When this value gets close to -20, performance will drop drastically Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to -100, performance will drop drastically RSSI RSSIįair but useful, fast and reliable data speeds may be attained, but marginal data with drop-outs is possible RSSI is displayed as a negative number from 0dBm, being the best/strongest signal, to -110dBm, being the weakest or no signal. RSSI is used when measuring the strength of 3G networks. RSSI is an abbreviation for Received Signal Strength Indicator and is a measure of cellular signal strength. RSRP and RSRQ are two of the most important performance indicators a modem utilizes when accessing a network. A few acronyms that you will encounter frequently are RSSI, RSRP, RSRQ and SINR, regardless of whether you are installing and managing a cellular router or deploying a cellular signal booster or amplifier system.
