When this value gets close to -100, performance will drop drastically Reliable data speeds may be attained, but marginal data with drop-outs is possible. You can find more information on RSRP and RSRQ values in the 4G (LTE) section of the Mobile Signal Strength Recommendations page. The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell reselection decision. RSRQ is a C/I type of measurement and it indicates the quality of the received reference signal.
RSRQ – Reference Signal Received Quality: Quality considering also RSSI and the number of used Resource Blocks (N) RSRQ = (N * RSRP) / RSSI measured over the same bandwidth. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ. It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband.
RSRP – Reference Signal Received Power is an RSSI type of measurement. In the procedure of handover, the LTE specification provides the flexibility of using RSRP, RSRQ, or both. In cellular networks, when a mobile device moves from cell to cell and performs cell selection/reselection and handover, it has to measure the signal strength/quality of the neighbor cells. Then, you can either change to another carrier or discuss with your existing one to resolve the issue.Reference Signals Received Power (RSRP) and Reference Signal Received Quality (RSRQ) are key measures of signal level and quality for modern LTE networks. Next time you get a poor signal on your iPhone, you can monitor the signal strength for a few days using this method. Here is the list of RSRP values (in dBm) and their corresponding signal strength status: rsrp Value (dBm) Both RSRP and RSRQ will always show negative values in the range. One is the signal strength ( RSRP) and other one is the signal quality ( RSRQ), both are important here to consider your iPhone has a good signal strength. The values of RSRP (Reference Signals Received Power) and RSRQ (Reference Signal Received Quality) are used to measure the signal level and quality for LTE networks like 4G or 5G.

Then, note the values for RSRP and RSRQ, which indicate the signal strength in decibel-milliwatts (dBm) and decibels (dB), respectively.
