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.


13/82Page 13

Occupied Bandwidth Requirement“Does most UE energy reside within its channel BW?”

Occupied bandwidth Measure the bandwidth of the LTE signal that contains

99% of the channel power

Occupied channel bandwidth

Occupied Bandwidth [MHz] 1.08 2.7 4.5 9 13.5 18

Channel bandwidth (MHZ) 1.4 3 5 10 15 20

Minimum Requirement: The

occupied bandwidth shall be less than

the channel bandwidth specified in the

table below

ACLR Requirements – UE caseDoes the UE transmit in adjacent channels?”

ACLR defined for two cases:•E –UTRA (LTE) ACLR1 with rectangular measurement filter (No TX/RX Filter defined)•UTRA (W-CDMA) ACLR1 and ACLR 2 with 3.84 MHz RRC measurement filter with

roll-off factor =0.22.

Transmitter Tester for RF Power Measurements

Agilent’s PXA, MXA and EXA signal analyzers have flexible power suite measurements that

can be set to make Channel Power, ACP, SEM and Spurious emission tests.

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

components and transmitters.

RF challenge. The different carrier aggregation configurations will stress the amplifier indifferent ways since each will have different peak-to-average ratios.

Defining Conformance

34

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

Test Specs

(TS…..)

- A set of test cases- Includes bands of operation

- Constantly evolves, over

‘releases’

Test Platform

(TP…..)

- Approved test systems/tools/instruments

- RF, PCT or RRM

- Must keep pace with standards

- Covers 80-90% of TS to be

approved

Validation

- Done by test lab to approvetest case implementation and

test platform

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.


37/82

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.


38/82

LTE RF Testing Definitions

38

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:

Chapter 6: Transmitter Characteristics

Chapter 7: Receiver Characteristics

Chapter 8: Performance Requirement

Chapter 9: Reporting of Channel State Information

39/82

Transmitter Characteristics

39

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
