ANNEX 6: IMPACT OF MFCN BANDWIDTH ON PMSE TX - MFCN LTE RX STUDIES
A6.1 INTRODUCTION
The LTE standard specifies several operating bandwidths (ETSI TS 136.101 - Table 5.6-1 and ETSI TS
136.104 - Table 5.6-1). The standard also differentiates between the Channel Bandwidth and the
Transmission Bandwidth (e.g. for a specific test channel). The relationship between the Channel Bandwidth
and the Transmission Bandwidth is provided in the Table 1 for both uplink and downlink.

(25RB, ETSI TS 136.104, Table 7.2.1-x)
(Sensitivity Wide Area BS = -101.5 dBm, ETSI TS 136.104 Table 7.2.1-1
Sensitivity Local Area BS = -93.5 dBm, ETSI TS 136.104 Table 7.2.1-2)
9 MHz
(50RB, ETSI TS 136.101, Table A.2.2.1.1-1)
(Sensitivity = -94 dBm, ETSI TS 136.101 Table 7.3.1-1)
The selection of an assumed bandwidth has an impact on the noise level assumed in the study, since the
noise level N is directly related to the bandwidth by the formula:
N = 10.log10(k.T) + 10.log10(BW) + NF
where k = Boltzmann constant; T = 290 K; BW = Bandwidth and NF = Noise Figure.
The Table below indicates the different values of N, for NF(LTE UE) = 9 dB, NF(LTE macro BS) = 5 dB and
NF(LTE pico BS) = 13 dB.

The present Annex demonstrates that the studies on the interference from PMSE to MFCN (LTE) are not
impacted by the choice of either the Channel Bandwidth of the Transmission Bandwidth.
A6.2 PMSE OUT-OF-BAND EMISSION LIMITS
In OOBE studies, we compare the level of OOBE in the receiver’s bandwidth with the noise level on the
same bandwidth, ensuring that a target ratio of interference on noise is respected, i.e. (OOBE – N) is
constant and independent of the receiver bandwidth.
Assuming 2 different receiver bandwidths BW 1 and BW 2, we would have:
N1 = 10.log10(k.T) + NF + 10.log10(BW 1)
And
ECC REPORT <No>- Page 16
N2 = 10.log10(k.T) + NF + 10.log10(BW 2)
Given that OOBE - N is constant:
OOBE1 - N1 = OOBE2 - N2
which implies that
OOBE1 - 10.log10(BW 1) = OOBE2 - 10.log10(BW 2)
Demonstrating that the normalized values of OOBE1 and OOBE2 (in dBM/MHz) are strictly identical.
Therefore, the choice of a specific receiver bandwidth has no impact on the acceptable level of OOBE
derived.
A6.3 BLOCKING
Assuming 2 different receiver bandwidths BW 1 and BW 2, we would have:
N1 = 10.log10(k.T) + NF + 10.log10(BW 1)
And
N2 = 10.log10(k.T) + NF + 10.log10(BW 2)
From the derivation of the blocking response derivation in ANNEX 4:
Blocking Response = N + 10.log10[10^(DSTANDARD/10) - 1] - IOOB-STANDARD
In ETSI TS 136.104 and ETSI TS 136.101, IOOB-STANDARD and DSTANDARD are independent from the
consideration of Channel Bandwidth of Transmission Bandwidth. Therefore:
Blocking Response (N2) = Blocking Response (N1) + (N2-N1)
In turn, in order to find the absolute level for blocking, it is necessary to calculate the IIB-TARGET based on the
noise floors (N1 and N2) and a Margin which is a function of DTARGET:
IIB-TARGET(N1) = N1 + Margin(DTARGET),
and
IIB-TARGET(N2) = N2 + Margin(DTARGET).
Therefore:
IOOB-TARGET(N2)
=
IIB-TARGET(N2) - Blocking Response (N2)
=
N2 + Margin(DTARGET) – [Blocking Response(N1) + (N2-N1)]
=
N1 + Margin(DTARGET) – Blocking Response (N1)
=
IOOB-TARGET(N1)
Which demonstrates that the Blocking Level derived is independent from the consideration of either the
Channel Bandwidth or the Transmission Bandwidth.
