"这篇文档是关于ETSI(欧洲电信标准协会)制定的3GPP TS 36.521-1 V8.2.1 Release 8版本，该技术规范详细阐述了LTE (Long Term Evolution) 用户设备(UE)的射频传输和接收的符合性测试标准。" 在无线通信领域，特别是移动通信系统中，ETSI制定的标准对确保设备之间的互操作性和性能至关重要。此文档详细规定了LET UE测试指标和测试方法，旨在确保UE在E-UTRA（演进型通用陆地无线接入）网络中的功能和性能达到预设标准。测试内容涵盖了一系列关键性能指标，包括但不限于： 1. 射频性能：这涉及到UE发射和接收信号的能力。测试可能包括频率误差、功率控制、调制精度、误码率等。 2. 功耗管理：UE的电池寿命和功耗效率是衡量其性能的重要因素。测试将评估UE在不同运行状态下的电源管理能力。 3. 接入和保持：测试UE能否成功连接到网络，并在各种网络条件下保持连接，包括不同速度下的移动性管理。 4. 小区选择和重选：UE应能正确选择最强信号的小区并根据信号变化进行重选，以保证服务连续性。 5. 数据传输性能：测试UE在不同信道条件下的数据传输速率和延迟，包括上行和下行链路。 6. MIMO（多输入多输出）技术：作为LTE的重要特性，MIMO测试涉及UE如何利用多个天线进行数据传输，以提高数据速率和系统容量。 7. 频谱效率：UE应能在给定的频谱资源内高效工作，以最大化网络资源利用率。 8. 安全性和隐私：测试UE的安全功能，如加密和鉴权机制，以保护用户数据和通信安全。 9. 兼容性：验证UE是否能与不同制造商的基站和其他UE无缝协作。这些测试不仅针对新设备的研发，也用于生产阶段的质量控制，以确保市场上的所有LET UE都满足ETSI设定的严格标准。测试结果通常由认证机构进行验证，以保证设备符合全球或区域性的法规要求。文档中的“Part 1: Conformance testing”部分特别关注符合性测试，这是设备认证过程的关键环节。它定义了详细的测试程序和步骤，以及合格判定的准则。通过这些测试，制造商可以确保其产品在发布前满足所有必要的技术要求，从而增强消费者对产品的信心。 ETSI的3GPP TS 36.521-1是LTE UE测试的权威指南，对于设备制造商、网络运营商以及监管机构来说都是不可或缺的技术参考资料。

3 Definitions, symbols and abbreviations

3.1 Definitions

For the purposes of the present document, the terms and definitions given in TR 21.905 [1] and the following apply. A

term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905 [1].

Channel edge: The lowest and highest frequency of the carrier, separated by the channel bandwidth.

Channel bandwidth: The RF bandwidth supporting a single E-UTRA RF carrier with the transmission bandwidth

configured in the uplink or downlink of a cell. The channel bandwidth is measured in MHz and is used as a reference

for transmitter and receiver RF requirements.

Maximum Output Power: The mean power level per carrier of UE measured at the antenna connector in a specified

reference condition.

Mean power: When applied to E-UTRA transmission this is the power measured in the operating system bandwidth of

the carrier. The period of measurement shall be at least one subframe (1ms) unless otherwise stated.

Occupied bandwidth: The width of a frequency band such that, below the lower and above the upper frequency limits,

the mean powers emitted are each equal to a specified percentage

/2 of the total mean power of a given emission.

Output power: The mean power of one carrier of the UE, delivered to a load with resistance equal to the nominal load

impedance of the transmitter.

PMI delay: The rate in basic time unit at which PMI is updated.

Reference bandwidth: The bandwidth in which an emission level is specified.

Transmission bandwidth: Bandwidth of an instantaneous transmission from a UE or BS, measured in Resource Block

units.

Transmission bandwidth configuration: The highest transmission bandwidth allowed for uplink or downlink in a

given channel bandwidth, measured in Resource Block units.

Transmit Diversity: Transmit diversity is based on space-frequency block coding techniques complemented with

frequency-shift time diversity when four transmit antennas is used.

4 General

Unless otherwise stated, the following reference conditions used by all test cases in this document are specified in TS

36.508 [7]:

• Connection Diagrams,

• Test Frequencies,

• Cell Settings,

• Reference Environments,

ETSI

ETSI TS 136 521

3GPP TS 36.521

• Environmental Conditions,

• Generic Connection Setup Procedures,

• System Information (SI),

• Message Contents.

Where a test requires one of the above reference conditions that are different, this will be specified within the test itself.

The Minimum Requirements defined in each test make no allowance for Measurement Uncertainty. Therefore, Test

Tolerances are used to relax the Minimum Requirements. If the Test Requirement differs from the Minimum

Requirement then the Test Tolerance applied for that test is non-zero. For each test the Test Tolerances are individually

calculated to create the Test Requirements. The Test Tolerance for each test and the explanation of how the Minimum

Requirement has been relaxed by the Test Tolerance is given in Annex F.3.

Downlink and Uplink transmissions are organized into radio frames with

ms 10307200

=×= TT duration. Two radio

frame structures are supported in this document:

•

Type 1, applicable to FDD,

•

Type 2, applicable to TDD.

In clauses 6 and 7 TX and RX test cases for FDD/TDD test cases are defined. FDD and TDD test scenarios/

requirements are included within the same test case. For test cases with any difference between the FDD and TDD

branches the test description part of the test case has been separated in two sections to cover the two technologies. The

applicability for the FDD and TDD branches are specified in TS 36-521-2.

In clause 8 the performance requirement test cases are defined. FDD and TDD performance requirement test cases are

defined in different clauses accordingly to the requirements specified in TS 36.101.

Unless otherwise stated, each test case is repeated for each operating band supported by the UE with the applicable test

frequencies, channel bandwidths, environmental conditions combinations indicated in the test case.

For test cases in clauses 6, 7, 8 the initial conditions of the downlink physical channels signal levels and downlink

physical channels required are specified in Annex C.0, Annex C.1 and Annex C.2.

5 Frequency bands and channel arrangement

5.1 General

The channel arrangements presented in this clause are based on the frequency bands and channel bandwidths defined in

the present release of specifications.

NOTE: Other operating bands and channel bandwidths may be considered in future releases.

5.2 Operating bands

E-UTRA is designed to operate in the operating bands defined in Table 5.2-1.
