<Power verification when LTE Carrier Aggregation Active>
General Note:
i. According to KDB941225 D05A v01r02, Uplink maximum output power measurement with downlink carrier aggregation
active should be measured, using the highest output channel measured without downlink carrier aggregation, to confirm
that uplink maximum output power with downlink carrier aggregation active remains within the specified tune-up tolerance
limits and not more than ¼ dB higher than the maximum output measured without downlink carrier aggregation active.
ii. Uplink maximum output power with downlink carrier aggregation active does not show more than ¼ dB higher than the
maximum output power without downlink carrier aggregation active, therefore SAR evaluation with downlink carrier
aggregation active can be excluded.
iii. The device supports downlink two carrier aggregation. For power measurement were control and acknowledge data is sent
on uplink channels that operate identical to specifications when downlink carrier aggregation is inactive.
iv. Selected highest measured power when downlink carrier aggregation is inactive for conducted power comparison with
downlink carrier aggregation is active, to confirm that when downlink carrier aggregation is active uplink maximum output
power remains within the specified tune-up tolerance limits and not more than ¼ dB higher than the maximum output power
measured when downlink carrier aggregation inactive.
v. For non-contiguous intra-band CA, the SCC selected to provide maximum separation from the PCC and must remain fully
within the downlink transmission band.
vi. The device supports uplink carrier aggregation for LTE B41C with a maximum of two 20MHz component carriers. For intra
band contiguous carrier aggregation scenarios, 3GPP 36.101 table 6.2.2A-1 specifies that the aggregate maximum allowed
output power is equivalent to the single carrier scenario. 3GPP 36.101 6.2.3A allows for several dB of MPR to be applied
when not-contiguous RB allocation is implemented. The conducted power and MPR setting in this device are permanently
implemented pre the 3GPP requirement.
vii. For Intra-band, contiguous CA, the downlink channels selected to perform the uplink power measurement must satisfy
3GPP channel spacing (5.4.1A of 3GPP TS 36.521 or equivalent) and channel bandwidth (5.4.2A) requirements.
