Transmit Power – UE“Does the UE transmit too much or too little?”
MOP (Maximum Output Power)• Method: broadband power measurement (No change from
UMTS)
MPR (Maximum Power Reduction)
• Definition: Power reduction due to higher order modulation and transmit
bandwidth (RB) – this is for UE power class 3
A-MPR (Additional MPR)
• Definition: Power reduction capability to meet ACLR and SEM
requirements
Agilent 89601A VSA provides power
measurement for each active channel
after demodulation
Channel power measurement using
swept spectrum analyzer
These methods are used to fine-tune the UE so that it can operate at high
data rates in deployments with higher spurious emissions and then scale
back its maximum power; for example, at the cell edge where the UE is
more sensitive to out-of-channel emissions.

Frequency Error Test (eNB and UE)“Does the eNB/UE accurately track UL/DL frequency?”
A quick test is use the Occupied BW measurement
(Agilent 89601A VSA SW shown) An accurate measurement can then be made using
the demodulation process
•Minimum Requirement (observedover 1 ms):
–UE: ±0.1 PPM
–BS: ±0.05 PPM
If the frequency error is larger than afew sub-carriers, the receiver demod
may not operate, and could cause
network interference

LTE-A CA
Agilent Solution:
• Signal Studio software generates LTE-Advanced
signals compliant to the Release 10 standard to
test power and modulation characteristics of
components and transmitters.
• Supports up to 5 component carriers within up to
160 MHz I/Q bandwidth with MXG vector signal
generator
• CCDF curve to get insight into the waveform
power statistics as system parameters are varied
Test Challenge: Characterizing the LTE-Advanced UE or eNB power amplifier presents
RF challenge. The different carrier aggregation configurations will stress the amplifier indifferent ways since each will have different peak-to-average ratios.

Specific set of tests performed:
• According to standards• By an approved test lab (could be manufacturer’s own)
• On an approved test platform
Only devices that pass the tests can be released into the market
All other types of tests are called pre-conformance or D&V

Challenges of LTE UE Testing
36
Many different LTE bands defined
Represent additional test requirements besides the inclusion of bothFrequency Division (FDD) and Time Division Duplex (TDD) modes.
OFDM
The use of multiple subcarriers instead of single carrier dramatically
increases the number of combinations under test.
Bandwidth
Different System BW are defined which makes more difficult to designers
optimize parameters valid for all bandwidths.
Fading & AWGN simulators are required
Fading simulators and AWGN generators are required tools for testing
LTE device robustness due to multipath reception and noise interference
effects.

Challenges of LTE UE Testing
37
Testing time
Due to the flexibility of the LTE air interface, the number of permutationsthat could be tested is enormous and therefore the testing time required
to execute them.
Inter-RAT requirements
Testing LTE UEs require exercising other radio access technologies(RAT) supported, as well as new inter-RAT tests required by the addition
of LTE.

3GPP TS 36.101 establishes the minimum RF characteristics and minimum performancerequirements for E-UTRA User Equipment (UE)
3GPP TS 36.521-1 specifies the measurement procedures for the conformance Radio
transmission and reception tests of the UE based on the requirements established by the TS 36.101
Four different sets of Tests are defined classified by the block of functionality under test:

Transmitter Characteristics

Transmit Power:
• To verify the UE maximum output power ; a too high maximum output power
may interfere other channels, a too small maximum output power decreasesthe coverage area.
Output Power Dynamics:
• To verify the UE’s ability to accurately transmit with a broadband outputpower for different power levels.
Transmit Signal Quality:• To verify the UE output signal quality. All the results are derived using the
same common algorithm (Global in-channel as described in TS 36.521-1 Annex E).
Output RF Spectrum Emissions:
• To verify that unwanted emissions are below the requirements.
Transmit intermodulation:
• It validates the capability of the transmitter to inhibit the generation ofsignals in its non linear elements
