LTE Downlink Power Calculation

this video explain the LTE reference signal power calculation, power of PDSCH type A and B using the parameters Pa, Pb, rho A and rho B.
with calculation examples.

Great Explain, Could you pls start series on CA

[@priyadarshini1130]

Hi, Thankyou very nicely explaned. Could you please give the spec ref for Prs=Psingle_port - 10*Log(12*Nrb) + Log(1+Pb).

At time 9:17, the example of Rho_B/Rho_A = 1.25 --> The Power of PDSCH_B in this cause should be = -2.03 dB + 18.22 right? (in TH-cam is -2.03+15.22). By the way, thank you very much for the great explanation.

Thank you!
Can you explain please why you add 10*log10(1+Pb) to Reference Power formula? is it just P_RS = P_singlePort -10*log10(12*Nrb)?

[@001HouseMusic]

Please explain, why Ppdsch_B= 20.88mW? In the scenario when Pb=0, Pa=-3. If Pa = -3, as in first example (Pb= 1, Pa= -3) RS Power is 18.2 (66.67mWatt) not 15.2. it means Ppdsch_B should be 0.6264*66.67=41.47 mW. Right?

Hi,
The RS power formula include the value of Pb:
Prs=Psingle_port - 10*Log(12*Nrb) + Log(1+Pb).
in the second example Pb=0 not 1, so the value of the RS power is 15.2 for Pb=0 and 18.2 for Pb=1.
