B.2.2. TX Measurement Parameter
The user can set the Carrier Leakage Position using the GUI by configuring Carrier Leakage Frequency under TX
Measurement Parameters as shown in Figure B.2.2-1.
Fig. B.2.2-1. TX Measurement Parameter – Carrier Leakage Frequency Setting
The following Remote Command can also be used to configure Carrier Leakage Frequency.
clf: Carrier Leakage Frequency Position
CFR at Carrier Frequency
Carrier Leakage is at the center frequency of the Aggregated Transmission Bandwidth
CCC at Each CC Center
Carrier Leakage is at the center frequency of each CC
For the case in Figure B.2.1-1 (a), the setting should be at Each CC Center (or send remote command “IBEM_CLFR
CCC”).
For the cases in Figure B.2.1-1 (b) and (c), the setting should be at Carrier Frequency (or send remote command
“IBEM_CLFR CFR”).
It is important to note that the Carrier Leakage Frequency Parameter is applicable only to intra-band contiguous CC
measurements. For non-contiguous measurements, the carrier leakage position is always set to at Each CC Center
(at the center frequency of each CC).
Additionally, when the Carrier Leakage Frequency parameter is set to at Carrier Frequency, there will be cases,
depending on bandwidth configuration, wherein PCC is allocated (SCC-1 is not allocated) but the carrier leakage is
at the SCC-1 band (i.e. PCC Channel BW < SCC-1 Channel BW). When configured as such, even if the carrier leakage
is at the SCC-1 band, carrier leakage is still measured at PCC and the result is obtained by the remote command
CARRLEAK? MAX, PCC (or CARRLEAK? MAX).
Conversely, for the case wherein SCC-1 is allocated (PCC is not allocated) but the carrier leakage is at the PCC band,
carrier leakage is still measured at SCC-1 and the result is obtained by the remote command CARRLEAK? MAX, SCC1.
This is in accordance with 3GPP TS36.521-1 6.5.2A.2 which states that carrier leakage is measured on the carrier
with RBs allocated.
