  • 5. Agilent Confidential What is “Conformance”? Question: Does a certain (wireless) device meet the requirements established by the applicable industry standards? Equipment Under Test Conformance Test System (EUT) Conformance Test 5
  • 6. Agilent Confidential When does Conformance happen? Components Development System Integration Certification Operator Acceptance R&D and Pre-Conformance Conformance Regulatory Conformance & Interoperability Performance & Usability
  • 7. Agilent Confidential Conformance Terminology Device Certification Program operated by different forums to increase global interoperability between mobile devices and networks based on technical requirements developed by bodies like 3GPP among others. GCF/PTCRB Groups formed by network operators, terminal manufacturers, test equipments, test houses and other organizations responsible for running mobile terminals certification. Validation Process that enable test equipment vendors to qualify their test platforms as approved for certitication. RCT/PCT/RRM Radio Frequency, Protocol and Radio Resource Management Conformante Test Systems respectively, which implements the test specifications for UE defined by the 3GPP. 7
  • 8. Agilent Confidential Conformance pillars Test Specs - Test cases - Includes bands - Constantly evolves, over „releases‟ 8 Test Platforms - Approved test systems/tools /instruments - RF, Protocol, RRM… - Must keep pace with standards - Proof validation for a certain percentage (e.g. 80%) to be approved Lab Accreditation - Lab must fulfill a set of requirements defined by a 3rd party, e.g. ISO 17025. - Must use validated TPs. - Might involve auditing process.
  • 9. Agilent Confidential LTE Conformance Ecosystem Operators Develops TTCN code for PCT testing - Device certification based on 3GPP standa RAN Working Groups (WG) RAN 1 – Layer1 How the system works? 1)Select and prioritize test cases 2) Create WI/RFT for specific requirem RAN 2 – Layer 2 and RRM 3) Validate Test Platforms/Test Cases RAN 3 – Overall architecture 4) Lab accreditation How to test the RAN 4 – RF performance analysis system works? RAN 5 – Conformance requirements
  • 10. Agilent Confidential 3GPP Test Specs Test spec Testing area 36.508 36.521-1 36.521-2 36.521-3 36.523-1 36.523-2 36.523-3 10 Common test environment RF Conformance Test Cases Applicability for RF & RRM (ICS) RRM Conformance Test Cases Protocol Conformance Test Cases Applicability for Protocol (ICS) TTCN for Protocol
  • 11. Agilent Confidential Frequency Bands – Release Independent An important aspect of frequency bands when it comes to the 3GPP releases is that they are “release independent”. This means that a band defined in a later release can be applied to an earlier release. This significantly simplifies the specifications. FDD TDD Release 8 1 – 17 (excl. 15,16*) 32 - 40 Release 9 18 - 21 Release 10 22 - 25 41 - 43 Release 11 26 - 29 44 Release 12 30?, 31?, … * Bands 15 and 16 are specified by ETSI only for use in Europe
  • 12. Agilent Confidential GCF GCF (Global Certification Forum) Certification is defined and maintained by GCF members collectively. The Conformance and Interoperability Group (CAG) identifies the Certification Entry Criteria (CEC) through laboratory testing. GCF CEC for WIs LTE Rel-8 RF & RRM WI080 LTE Rel-8 Protocol Conformanc e Test Cases 12 WI150 WI090 WI081 082 TPAC WI091 092 WI162 Rel-9 & CA

  • 14. Agilent Confidential Validation of Test Platforms/ Test Cases Certification bodies do not adopt the entire 3GPP test specs Each certification body SELECTS a group of TEST CASES and DEFINES PRIORITY based on operators‟ plans GCF: Work Items (WI) PTCRB: Request For Testing (RFT) Test system vendors DEVELOP TEST CASES on their test platforms Each test system vendor selects an ACCREDITED LAB to VALIDATE their test cases using reference UEs The lab submits a validation report to the specific certification body for approval, ENABLING the TEST SYSTEM and TEST CASE FOR CERTIFICATION 14
  • 15. Agilent Confidential Certification database When is a test case mandatory for Certification?... Does it apply to my device? Has it been validated? …In which Test Platforms? 15
  • 16. Agilent Confidential Test Cases - Categories A: Test case mandatory for Certification. B: Test case validated with exceptions. C: Test case validated but not applicable for certification yet (due to WI not active or frequency band not active). D: Test case downgraded. 16 P: Test case not validated in any platform. It can only be validated at a CAG meeting.
  • 17. Test Cases - Applicability PTCRB and GCF define a special field for every test case in order to indicate whether the test case has to be executed in all supported bands or only in the „main band‟ supported. In GCF: • RF test cases (Sec. 6 and 7) and RRM test cases from Sec. 9 shall be run for each band supported by the Device. • All other RF and RRM TCs, plus all protocol test cases except for few exceptions, shall be run only once in a band chosen by the Device Manufacturer. 17 Agilent Profile Dec. 1, 2011

  • 48. Agilent Confidential LTE-CA: Testing challenges (I) • CA testing requires emulating multiple cells and combination of bands. • Analyze multiple Tx/Rx chains simultaneously in multiple bands. • CA performance test setups are complex (multiple cells, faders, AWGN generators and combination circuitry). • Complex connections with test systems due to different UE antenna configurations. 49
  • 49. Agilent Confidential LTE-CA: Testing challenges (II) Test Challenge #1 : Demodulating Inter-Band aggregated signals require signal analyzer with bandwidth that spans multiple frequency bands. Test Challenge #2 : Intermodulation and cross-modulation within the UE. Need to design front-end components that help reduce harmonics and other intermodulation products. Test Challenge #3 : When Inter-Band aggregation and MIMO spatial multiplexing is combined, test set-ups may become very complex. 50
