[srsran-users] LTE processing bandwidth

[Nadia Patricia Yoza Mitsuishi]

Hello everyone!

I'm interested in the SNR measurement reported by srsRAN and I understand
that it's measuring the noise as EPRE-RSPR and the signal as RSRP.

Does anyone know what's the processing bandwidth of the LTE signal that is
considered for these measurements? For example, for a LTE signal of 10 MHz
bandwidth, is it actually considering n_PRB*srsRAN_NRE*RE=50*12*15000= 9
MHz or 10 MHz?
where:
n_PRB: number of physical resource blocks
srsRAN_NRE: number of resource elements
RE: resource element

In other words, does the signal measurement consider the out-of-band
leakage outside the 9 MHz bandwidth?

Thanks,
