RSRP - Reference Signal Received Power: RSRP is a RSSI type of measurement, as follows there are some definition of it and some details as well. It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ RSRQ=10*log(N*RSRP/RSSI) N étant le nombre de ressource block. Mesurer le RSRQ est intéressant particulièrement aux limites des cellules, positions pour lequelles des décisions doivent être prises pour accomplir des Handovers et changer de cellule de références. Le RSRQ mesuré varie entre -19,5dB à -3dB par pas de 0.5dB In the procedure of handover, the LTE specification provides the flexibility of using RSRP, RSRQ, or both. RSRP - Reference Signal Received Power is an RSSI type of measurement. It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP.

. It is the power of the LTE Reference Signals spread over the full bandwidth (RSSI) and narrow-band (RSRP). A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ Le RSSI (Received signal strength indicator) est une mesure interne au terminal qui, avec le RSRP, elle lui permet de calculer le RSRQ (indicateur de qualité du signal). Le RSSI a une valeur plus élevée de 20 à 30 dB que le RSRP, selon la largeur de bande utilisée (5 à 20 MHz) et qqs autres paramètres (bruit venant des cellules voisines) qu'il serait trop long de décrire ici
Below are explanations of the LTE signal strength values (and also RSSI in relation to LTE): SINR/SNR - The signal-to-noise ratio of the given signal. RSRP - The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). RSRQ - Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good) Example 3 >: RSRP/RSRQ/RSSI/SINR at driving/handover situation . Following plot is from the data captured by a drive test tool Azenqos Drive Test tool (AZQ Android). I got the log captured by the tool and exported the data as csv file and then plot it on Microsoft Excel. The map displaying the path of the measurement shown at the bottom is the one automatically created by AZQ reporting tool. RSRP = -102 dBm. RSRQ = -16 dB. SINR = -1.8 dB. In this case, the signal quality is actually very poor. This could be due to the device being some distance away from the LTE transmitter. It's also possible that something is interfering with the signal, such as a building or other obstructions between the device and the tower. RSSI RSSI Signal strength Description > -65 dBm Excellent: Strong.
The equation for LTE RSRQ is defined below: RSRQ = RSRP/ (RSSI/N) Where N is number of resource blocks over which RSSI is measured. RSSI is calculated as a linear average of the total power measured across OFDMA symbols which contain reference symbols transmitted from first antenna port, e.g. symbols 0 and 4 when MIMO is not used. RSRQ also takes antenna connector of UE as reference point. As RSSI applies to the whole spectrum we need to multiple the RSRP measurement by N (the number of resource blocks) which effectively applies the RSRP measurement across the whole spectrum and allows us to compare the two. Finally SINR is a measure of signal quality as well. Unlike RSRQ, it is not defined in the 3GPP specs but defined by the UE. This page mentions RSRP,RSRQ and SINR measurements used in 5G NR system.The definitions and use of RSRP, RSRQ and SINR in 5G NR are also mentioned.RRC Information Elements (IEs) which carries these measurements (i.e. RSRP, RSRQ, SINR) are also mentioned. It defines SS-RSRP, CSI-RSRP, SS-RSRQ, CSI-RSRQ, SS-SINR and CSI-SINR Below are explanations of these values (and also RSSI in relation to LTE): SINR/SNR - The signal-to-noise ratio of the given signal. RSRP - The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). RSRQ - Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good). RSSI - Represents the. In fact, during the exposure we was talking about SINR, RSRQ & RSSI definition. Of course, if you would like to analyze in details the SINR in this case, you will have to adapt the formula. Let us know if would like to do it; we could do it together and write another article about it. We are looking for new Authors. 3 January 2017 at 0:26 . Reply. Abubaker M.

LTE Metrics including RSRP, RSRQ and SINR LTE Cellular Networks. Summary: RSRQ and SINR are key metrics for LTE systems including CableFree LTE-A Infrastructure. This page explains the technical differences. In LTE - as any wireless system - the performance has a direct relationship with the RF conditions at the time. To aid with performance analysis in LTE, it is typical to define some. SINR, RSRP, RSSI and RSRQ Measurements in Long Term Evolution Networks Article (PDF Available) in International Journal of Wireless & Mobile Networks 7(4):113-123 · August 2015 with 9,088 Read 5G NR Measurements: RSRP, RSSI, RSRQ and SINR. June 25, 2019 June 25, 2019 admin Tech Fundas. In LTE, the UE measurements are done for RSRP, RSRQ and SNR associated with CRS (Cell Specific Reference Signal) . 5G NR uses SS (Synchronization Signal) and CSI (Channel State Information) instead of CRS, so 3GPP had put new definitions for UE measurements in place, and some of these are discussed.
Vysvětlení parametrů signálu RSRP RSRQ SINR a RSSI. 6. 5. 2019 14:46. Pokud máte zmatek v hodnotách síly a kvality signálu, které se objevují v menu některých kvalitnějších modemů, tento článěk Vám pomůže některé parametry trochu více objasnit a vysvětlit. Podlě těchto parametrů můžete často zjistit příčinu nenadálých výpadků připojení k internetu. RSRQ = RSRP / (RSSI / N) = RSRP / (2 x RSRP x N/ N) = 0.5 = -3 dB During handover, operators can configure paramete for UE to do measurement of RSRP alone or RSRQ or both. In this way, it can help UE to make better decisions for mobility measurements. SUMMARY In a nutshell it can be concluded, that RSRP provides information about signal strength , while RSSI helps in determining interference. RSRQ is defined as (N x RSRP)/RSSI in 3GPP 36.214, where N is the number of RBs over the measurement bandwidth. RSRQ = N × RSRP/(EUTRA carrier RSSI), As 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. Therefore, (N x RSRP)/RSSI indicates What is the portion.

Reference Symbol Received Power (RSRP): RSRP is the linear average of the downlink reference signals across the channel bandwidth RSRP provides information about signal strength and gives no indication of signal quality RSRP measurements are used in handover, cell selection and cell re-selection Reference Signal Received Power RSRP is the linear average of the received reference signal level. Thanks to RSRP, it is possible to compare the strengths of signals from individual cells in LTE networks. It is important parameter for cell selection or handover
Since RSRP and RSRQ values are negative, the closer the value to 0, the better is the RSRP/RSRQ. Hence, the maximum and minimum RSRP values are found to be -66.1dBm and - 125dBm respectively, whereas the maximum and minimum RSRQ values are seen to be -1.9dB and -15dB respectively Reference Signal Received Quality (RSRQ) Finally the RSRP is used as the criterion for cell reselection As 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 RSSI -63dBm SINR 9 dB RSRP -89 dBm RSRQ -12dBm.

RSRP (potenza del segnale di riferimento ricevuto) Il valore RSRP è uno dei valori più importanti quando si tratta di valutare il valore di ricezione proprio e la qualità della ricezione. Viene misurata direttamente dal terminale. Reference Signals Received Power (RSRP) and Reference Signal Received Quality (RSRQ) are key measures.
To conclude, here are a few takeaways about RSSI and RSRP as signal strength measurement techniques for LTE: RSSI varies with LTE downlink bandwidth. For example, even if all other factors were equal, VZW 10 MHz LTE bandwidth RSSI would measure 3 dB greater than would Sprint 5 MHz LTE bandwidth RSSI. But that does not actually translate to stronger signal to the end user. RSSI varies with LTE. An uncomfortable property of the RSRQ to SINR mapping is that it depends on the instantaneous serving cell sub-carrier activity factor x, which is typically not known in live network measurements The value of x = 1 indicates full load such that all sub-carriers of one transmit antenna are transmitted for the OFDM symbol carrying R0 RSRQ = (N * RSRP) / RSSI. RSSI = Received Signal Strength Indication: total received power in the certain bandwidth including traffic channel power, control channel power, thermal noise and etc. RSRP (Rx) = Reference Signal Received Power: average received power of reference signal which is carried on Resource Element (RE). Synchronization Signal Reference Signal Received Power. SS-RSRP is the. Reference Signal Received Power (RSRP) is a cell-specific signal strength related metric that is used as an input for cell resection and handover decisions. For a particular cell, RSRP is defined as the average power (in Watts) of the Resource Elements (REs) that carry cell-specific Reference Signals (RSs) within the considered bandwidth Understanding The Differences Between RSSI vs. RSRP vs. RSRQ. RSRP is a metric specific to 4G LTE that looks at the average of all the RF power in the passband. It measures the average amount of resource elementals that carry reference signals that are cell-specific over the entirety of the bandwidth. RSSI is certainly a valid metric to use but is better utilized for 3G technologies including.
SINR CQI RSRP RSSI RSRQ SINR - Signal to Interference plus Noise Ratio Signal to Interference plus Noise Ratio (SINR) is measured by UE on Resource Block (RB) basis. UE computes SINR on each RB, converts it to CQI and reports it to eNodeB where it is used to select the most suitable MCS for user data transmission in particular RB. SINR value defines the MCS to be used for a RB i.e. the number. Below are explanations of the LTE signal strength values (and also RSSI in relation to LTE): SINR/SNR - The signal-to-noise ratio of the given signal. RSRP - The average power received from a. Let's assume that all RE powers are same like Rx Power (RSRP). Then. RSRQ = (N * RSRP) / RSSI = (100 * 16.66) / (1200 * 16.66) = 1/12 = 0.083 mW. Conversion to dB . RSRQ = 0.083mWatt = 10*log(0.083) ≈ −10.8 dB * In this calculation Antenna Gain, Feeder Loss, Path Loss was not taken into account, you can refer to RSRP tag for details. The following two tabs change content below. Bio. I working on enhancing the SINR value for LTE, I know there is a minimum requirement for SINR on LTE based on MCS (QPSK, 16QAM, 64QAM)

RSRP is a RSSI type of measurement. It measures the average received power over the resource elements that carry cell-specific reference signals within certain frequency bandwidth. RSRP is applicable in both RRC_idle and RRC_connected modes, while RSRQ is only applicable in RRC_connected mode. In the procedure of cell selection and cell reselection in idle mode, RSRP is used. RSRQ is a C/I. This is the reason, RSRQ (Reference Signal Receive Quality) measurement and calculation is based on both RSRP and RSSI. Since the logarithmic ratio of 100 subcarriers to one subcarrier is 20 dB (e.g. 10 × log 100 = 20), RSSI tends to measure about 20 dB higher than does RSRP • In practice, mapping from RSRQ to SINR seems difficult - Currently available measurement UEs and scanners report SINR directly x RSRQ SINR 1 12 RSRP vs. SNR -15.00 -10.00 -5.00 0.00 5.00 10.00 15.00 20.00 25.00 30.00 35.00 40.00 -135 -130 -125 -120 -115 -110 -105 -100 -95 -90 -85 -80 -75 -70 RSRP (dBm) SNR(dB) SNR RSRQ vs SINR -10.00 -5.00 0.00 5.00 10.00 15.00 20.00 25.00 30.00 -20 -19. In LTE, the measured physical layer indicators in- clude reference signal received power (RSRP), received signal strength indicator (RSSI) and reference signal received quality (RSRQ). Whereas RSRP is easy to interpret, the more complex RSRQ is a frequent source of misunderstanding. In this paper, we discuss RSRQ in detail Lets try to calculate RSRP, RSSI and RSRQ for one very simple case of one resource block with 12 sub carriers and 0.5 ms in time domain. Let's assume the power of reference symbols (shown by red square) and power of other symbols carrying other data channels (shown by blue square) is same i.e. 0.021 watt Since RSRP is linear average of downlink reference signal for given channel bandwidth. RSRQ is th Reference Signal Received Quality and it can be defined using following. RSRQ= (N* RSRP)/RSSI; As 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
