📐 PUCCH Power Calculation

Formula: P_PUCCH = min(P_CMAX, P_O_PUCCH + 10·log10(2^μ · M_RB) + PL + Δ_F_PUCCH + Δ_TF + g(i))

P_PUCCH = min(23, -90 + 3.01 + 44 + 0 + 0 + 0) = -42.99 dBm

P_PUCCH = — dBm

P_O_PUCCH: -90 dBm

Bandwidth: 3.01 dB

PL: 44.00 dB

Δ_F: 0.00 dB

Δ_TF: 0.00 dB

g(i): 0.00 dB

P_PUCCH: -42.99 dBm

Headroom: 65.99 dB
