13.3 LTE Conducted Power
13.3.1 Largest channel bandwidth standalone SAR test requirements
QPSK with 1 RB allocation
Start with the largest channel bandwidth and measure SAR for QPSK with 1 RB allocation, using the RB offset and
required test channel combination with the highest maximum output power among RB offsets at the upper edge, middle
and lower edge of each required test channel. When the reported SAR is ≤ 0.8 W/kg, testing of the remaining RB offset
configurations and required test channels is not required for 1 RB allocation; otherwise, SAR is required for the
remaining required test channels and only for the RB offset configuration with the highest output power for that
channel.8 When the reported SAR of a required test channel is > 1.45 W/kg, SAR is required for all three RB offset
configurations for that required test channel.
QPSK with 50% RB allocation
The procedures required for 1 RB allocation in section 4.2.1 are applied to measure the SAR for QPSK with 50% RB
allocation.9
QPSK with 100% RB allocation
For QPSK with 100% RB allocation, SAR is not required when the highest maximum output power for 100 % RB
allocation is less than the highest maximum output power in 50% and 1 RB allocations and the highest reported SAR
for 1 RB and 50% RB allocation in sections 4.2.1 and 4.2.2 are ≤ 0.8 W/kg. Otherwise, SAR is measured for the
highest output power channel; and if the reported SAR is > 1.45 W/kg, the remaining required test channels must also
be tested.
Higher order modulations
For each modulation besides QPSK; e.g., 16-QAM, 64-QAM, apply the QPSK procedures in sections 4.2.1, 5.2.2 and
4.2.3 to determine the QAM configurations that may need SAR measurement. For each configuration identified as
required for testing, SAR is required only when the highest maximum output power for the configuration in the higher
order modulation is > ½ dB higher than the same configuration in QPSK or when the reported SAR for the QPSK
configuration is > 1.45 W/kg.
13.3.2 Other channel bandwidth standalone SAR test requirements
For the other channel bandwidths used by the device in a frequency band, apply all the procedures required for the
largest channel bandwidth in section 4.2 to determine the channels and RB configurations that need SAR testing and
only measure SAR when the highest maximum output power of a configuration requiring testing in the smaller channel
bandwidth is > ½ dB higher than the equivalent channel configurations in the largest channel bandwidth configuration
or the reported SAR of a configuration for the largest channel bandwidth is > 1.45 W/kg. The equivalent channel
configuration for the RB allocation, RB offset and modulation etc. is determined for the smaller channel bandwidth
according to the same number of RB allocated in the largest channel bandwidth. For example, 50 RB in 10 MHz
channel bandwidth does not apply to 5 MHz channel bandwidth; therefore, this cannot be tested in the smaller channel
bandwidth. However, 50% RB allocation in 10 MHz channel bandwidth is equivalent to 100% RB allocation in 5 MHz
channel bandwidth; therefore, these are the equivalent configurations to be compared to determine the specific channel
and configuration in the smaller channel bandwidth that need SAR testing.
