Power headroom Range is -23 to 40 but how i get the negative PH if the maximum power of UE is 23dbm and Pusch Power is min { pmax ,Po_pusch }.
Can anyone explain in detail how Negative PH comes ?
How can I figure out real power value from this report value ?
In LTE after giving grant,I sent DCI after that I receive UL packets which has almost zero power(modem side). what could be the reason here?
I am trying to simulate an OFDM signal with LTE specifications. After taking ifft of the modulated symbols I want to plot the power specteral density of the signal. Somehow the power spectral density is not correct if I take directly the ifft output. My question is what needs to be done to the output of ifft samples to get the correct PSD.
