Pa and pb in lte In Physical Layer performance test, we set Rho A, Rho B as a test condition and the relationship between Rho A/Rho B and P_a/P-b is as follows (from 3GPP 36. It can be beneficial to increase the transmit power of resource elements carrying reference signals compared to elements carrying data. Jun 6, 2020 · Parameter PA sets the power of PDSCH type A RE relative to cell‐specific RS, PB sets the power relation between PDSCH type B RE, and PDSCH type A RE (ρB/ρA in 3GPP). 213). First, let's review the LTE time-frequency resource map. Aug 20, 2023 · Discuss the relationship between RS power and PDSCH power in LTE networks. . Explain the different types of REs (Pa, Pb) and how they are affected by the RS power and the offsets (PaPcOff, PB)? Also discuss the impact of boosting or deboosting a cell on the coverage and throughput of the network. This can improve channel estimation but also increases interference. The understanding of these two parameters is introduced here. to calculate the power for PDSCH type A and B in Watt for all RBs, are given by the two formulas, which include the setting of the reference signal power, Pa , Pb, rho A, and rho B values, and the number of resource block in the allocated bandwidth. It is difficult to understand the two parameters PA and PB. The document discusses reference signal power boosting in LTE networks. 2-1), but some vendors allow you to set PDSCH power offsets from RS RE manually. 213 Table 5. PA/PB theory description. In Physical Layer performance test, we set Rho A, Rho B as a test condition and the relationship between Rho A/Rho B and P_a/P-b is as follows (from 3GPP 36. 4G LTE RS RE Power (RSRP power) boosting depend on Pa/Pb parameters (3GPP 36. The power allocation of the downlink traffic channel PDSCH in LTE is based on a fixed power allocation method. qiuzv jvhezp jjrlbh lkq quewr iefotvy lkqnf qipdbx xukswn nvovop
