RSRP threshold configured by the network as defined in TS 38.331, but notįor the purpose of measurement reporting. Note: The value of RSRP_127 is applicable for The range in the signalling may be larger than the guaranteed accuracy range. RSRP in NrUePhy::ReportRsReceivedPower and NrUePhy::ReceivePss. The mapping of measured quantity is defined in Table 10.1.6.1-1. Public group for discussing 5G-LENA topics. The reporting range of “SS-RSRP and CSI-RSRP for L1” reporting is defined from -140 to -44 dBm with 1 dB resolution RSRP range in 5GThe reporting range of “SS-RSRP for 元” reporting is defined from -156 dBm to -31 dBm with 1 dB resolution. So, RSRP, RSRQ, RSSI and SINR all 4 parameters are used to measure the signal strength of a UE, that’s present in a network.Ī UE reporting RSRP, RSRQ, RSSI and SINR information (detection based) on 2 layers “元 Layer” and “L1 Layer”įor example, in QXDM log you will see the RSRP, RSRQ, RSSI and SNR information for Layer-1 in “NR5G ML1 Searcher Measurement Database Update Ext” and,įor Layer-3 you will see the RSRP, RSRQ and SNR parameters information in “Measurement report” which is triggered by UE. SINR is a positive number the greater the value, the better quality the signal.There are multiple detection parameters are there, that’s are used to know “how much a UE feel better in a network”. Even a small increase in RSRQ can result in a significant improvement in cellular data rates.Īlthough SINR ( Signal to Interference-plus Noise Ratio) is not included in the 3GPP mobile broadband specifications, some equipment manufacturers use this traditional way of measuring the ratio of signal to noise. A cell signal booster can’t improve the quality (RSRQ) of the signal, but an outside directional antenna ( an LPDA or a Yagi) can isolate a specific cell tower and help reduce interference from other nearby towers. Like RSRP, RSRQ is a negative number therefore, −8 dB RSRQ is higher-quality signal than −12 dB RSRQ.Ĭell signal boosters amplify the strength (RSRP) of the ambient cell signal available at the outside antenna. The greater the RSRQ value, the less interference the signal is getting from other cells operating at or near the same channel. Cell signal qualityĤG LTE and 5G cell signal quality are measured by RSRQ ( Reference Signal Received Quality) in decibels ( dB).
Increasing the strength of a poor-quality signal is like turning up the volume on a television that’s only producing static-all you get is louder static. Signal strength is important, but it’s only as good as the quality of the signal itself. ( Learn more about cell signal strength and how to measure it here.)
RSRP is usually a negative number, so −90 dBm RSRP is stronger than −100 dBm RSRP. The greater the RSRP value, the stronger the cellular signal. 4G LTE and 5G cell signal strength are measured by RSRP ( Reference Signal Received Power) in decibel-milliwatts ( dBm).
