![]() ![]() ![]() ![]() Just to save a little bit of time for readers, I expanded the table to show all the possible RSRQ value and mapping absolute power. It sends a non-negative value ranging from 0 to 34 and each of these values are mapped to a specific range of real RSRQ value as shown in the following table from 36.133. Reference Signal Received Quality (RSRQ) measurement on mobile video streaming over an LTE network and. When it report this value, it does use the real RSRQ value. (RSSI), Reference Signal Received Power (RSRP) and. UE usually measures RSRP or RSRQ based on the direction (RRC message) from the network and report the value. The greater the RSRQ value, the less interference the signal is getting from other cells operating at or near the same channel. ![]() Since this is the ratio of two different power value, the unit of RSRQ is dB and the value would be always negative (because RSSI value will aways be larger than N x RSRP) By deviding RSRP by RSSI, it could give some information about interference as well in addition to the strength of the wanted signal. Indicates "What is the portion of pure RS power over the whole E-UTRA power recived by the UE".Īs you see, this is not the direct measurement, it is a kind of derived value from RSRP and RSSI. RSRQ is defined as (N x RSRP)/RSSI in 3GPP 36.214, where N is the number of RBs over the measurement bandwidth.Īs you see from the definition of RSSI, RSSI co ntains all sorts of power including power from co-channel serving & non-serving cells, adjacent channel interference, thermal noise, etc. ![]()
