Reply To: why thermal noise divided by half RB ?


Hi Omar,

for accumulating the interference, two samples are used per RB (trade-off between accuracy and complexity). This is also done for the noise power and therefore nSC = 2*nRB. To be consistent, this number is multiplied with half of the noise power per RB. In the end, it equates to thermal noise power density multiplied by total bandwidth.

Best regards,
