Rsrq values10/31/2023 ![]() (because RSRP is measured over 1 resource element and RSSI per resource block is measured over 12 resource elements). If all resource elements are active and are transmitted with equal power, then As a result RSRP, RSRQ and SINR are associated with SS and CSI. The RRM functionalities comprise of a range of algorithms employed for the optimal utilisation of radio resources. So, when there is no traffic, and assuming only the reference symbols are transmitted (there are 2 of them within the same symbol of a resource block) from a single Tx antenna then the RSSI is generated by only the 2 reference symbols so the result becomes The best value of RSRP is about -3 dB and worst value can be -19.5dB. 3GPP has provided a table shown below, by using this table the integer value can be translated to a range of RSRP value in dB. Similar to RSRP, UE reported an integer value to eNodeB and its range is from 0 to 34. However, SNR or SINR is very common RF term and the correlation of SINR and RSRQ can be approximated (in dB) as below. For this, SNR or SINR would be more accurate. I know the MIB ciscoWanCellExtMIB 1.3.6.1.4.1.9.9.817 has aggregate info regarding some of these values, but in the Universal Device Poller. You can get more absolute criteria for signal quality. ![]() dBm so RSRQ uses dB as a measurement unit. As you see in the RSRQ page, the maximum RSRQ value you can achieve is -3dB. As RSRQ is a ration of two signal powers with same same unit i.e. RSRQ is a calculated value from RSRP and RSSI is measure of signal and interference. ![]() Here is the script.RSRQ is th Reference Signal Received Quality and it can be defined using following.Īs per the definition of RSSI, It is wide band power including signal power from serving cell, co-channel neighbour cell, interference from other cell interference and noise, in similar word one can say that RSRQ define the purity of Reference Signal (RS) across the system bandwidth. ![]()
