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. Quality is calculated over all data in the Measurement Interval.There are multiple detection parameters are there, that’s are used to know “how much a UE feel better in a network”. Carrier RSSI (Received Signal Strength Indicator) depending on its frequency assignment and application. or TDD Time Division Duplex: A duplexing technique dividing a radio channel in time to allow downlink operation during part of the frame period and uplink operation in the remainder of the frame period. This system uses DSSS and either FDD Frequency Division Duplex: A duplex scheme in which uplink and downlink transmissions use different frequencies but are typically simultaneous. N = number of resource blocks over which RSRP and RSSI are calculated (the LTE Long Term Evolution demodulator includes all resource blocks in the frame bandwidth)Į- UTRA UMTS Terrestrial Radio Access: A W-CDMA standard developed ETSI, ARIB and the TIA Telecommunications IndustryĪssociation (U.S.): One of the Telecommunications standards setting bodies in the United States. RSRQ = N * RSRP / ( E-UTRA Evolved Universal Terrestrial Radio Access Carrier RSSI Received signal strength indication) Quality, or RSRQ, is a measure of the quality of the received signal as defined in Section 5.1.3 of 3GPP TS Technical Specification 36.214 and is given by the following equation Menu Path: Trace > Data > Demod > Error Summary
