Quality is calculated over all data in the Measurement Interval.Maybe there's an error in 36.214 because the RSRP definition looks the same as the RSSI definition, which would make RSRQ always zero (as it says 'measurements in the numerator and denominator shall be made over the same set of resourceīlocks.') and it says RSSI only considers ref symbols. 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
