WebOct 19, 2024 · RSRQ (LTE only) RSRQ is the Reference Signal Received Quality is a C/I type of quality measurement and it indicates the quality of the received reference signal (similar to EC/IO in 3G) RSRQ is a calculated value from RSRP and RSSI . As RSRQ is a ratio of two signal powers with same same unit ( i.e. dBm) it uses dB as a measurement unit. WebMar 14, 2024 · meridius. Member. Feb 3, 2024. #1. My understanding is that the higher your phone signals dBm (decibel-milliwatts) are i.e. closer to zero the better. Also that if your ASU (Arbitrary Strength Unit) is higher the better and that both these measurements of phone signal strength are more accurate than the signal bars on your phone.
