The mean SINR is 12. N is the number of Physical Resource Blocks (PRBs) over which the RSSI is measured, typically equal to system bandwidth. Check UL Power settings and SINR on. Similarly Hysterysis IE value is calculated as IE Element * 0. The RSRP for each of the transmit-receive beam pairs can be measured to determine the beam pair link with the maximum RSRP. 214, where N is the number of RBs over the measurement bandwidth. 2. From Android’s API GPS velocity. As a result of the calculations, a new mathematical RSRQ is the ratio between the RSRP and the Received Signal Strength Indicator (RSSI), and depending on the measurement bandwidth, means the number of resource blocks. The mapping of measured quantity is defined in the table below: RSRP mapping 3GPP TS 36. 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. Calculator is based on 3GPP communication. g, WCDMA Cell or GSM Cell). To calculate RSRP, the power in each one of those subcarriers is averaged.

Moreover, the operator’s pathless data to various cells (L ue) and shadow fading having log-normal distribution plays a role in RSRP calculation. Applied mapping is shown below. e. From these information, you. It is observed that at this RSRP ranges, PC2 uplink throughput performance is consistently better than PC3 with an increased gain as RSRP degrades towards the edge coverage of the cell. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ. Single-codeword limits the number of transmission layers to 4. UE reports not RSRP value but an integer value between 0 and 97. The best value of RSRP is about -3 dB and worst value can be -19. The method of claim 1, wherein the one or more metrics comprise at least one of signal to noise (SNR), reference signal received power (RSRP), or path loss measurements.
