When this equipment accesses mobile cellular services, it can be stationary or mobile within the cellular service area, and the equipment can provide services to one or more users at the same time. 3.1.2 Ancillary Equipment (AE) Equipment used in connection with wireless communication equipment, with the following conditions met: — being connected to wireless communication equipment to provide additional operational or control features, such as extending the operation or control to other locations; — cannot be used independently of the wireless equipment, otherwise it cannot provide user functions alone; — the wireless communications equipment to which it is connected is still capable of implementing the preset operations such as transmitting and/or receiving without this ancillary equipment (i.e., the ancillary equipment is not the subunit of the basic function of master equipment) 3.1.3 Associated Measurement Equipment (AME) Equipment, such as a base station simulator, that facilitates the UE's normal operation and/or monitors its working status. The AME should be placed outside the test area, but it may also be placed in the test area. 3.1.4 Channel Bandwidth The single-carrier transmission bandwidth configured in the uplink and downlink of the cell. The channel bandwidth unit is MHz, which provides a reference for the radio frequency equipment of the transmitter and receiver. 3.1.5 Enclosure Port Physical boundary of the equipment, through which the electromagnetic field radiates or penetrates; in case of a plugin, the physical boundary is defined by the host unit 3.1.6 Traffic Mode The mode in which the user equipment is turned on and has established a connection with the radio resource control (RRC) module. 3.1.7 Idle Mode The mode in which user equipment is turned on but no RRC connection is established. 3.1.8 Integral Antenna The antenna is permanently attached to the equipment and is considered part of the enclosure port, and may be an internal or external antenna. 3.1.9 Maximum Throughput The maximum amount of successfully transmitted data (measured in bits, bytes, packets, etc.) per unit time for the reference test channel. 3.1.10 Necessary Bandwidth The bandwidth required to guarantee the quality and transmission rate of information transmission under specified conditions for a given type of transmission. 3.1.11 Out of Band Emissions Emissions at one or more frequencies just outside the necessary bandwidth resulting from the modulation process, which exclude spurious emissions. 3.1.12 Port Particular interface between specified equipment (and external electromagnetic environment (as shown in Figure 1) Figure 1 Examples of Ports 交流电源端口 AC power port 直流电源端口 DC power port 接地端口 Earthing port 机箱端口 Enclosure port 信号/控制端口 Signal/control port 天线端口 Antenna port 有线网络端口 Wired network port 3.1.13 Spurious Emission Transmission on a single or multiple frequency points outside the necessary bandwidth, the level of which may be reduced without affecting the corresponding information transmission. Spurious emissions include harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products, except for out-of-band emissions. 3.1.14 Wired Network Port This port is intended for the transmission of voice, data and signals, and is directly connected to single-user or multi-user communication networks such as public telephone networks, xDSL, Ethernet and similar networks. 3.1.15 Throughput The maximum number of valid data bits per second that can be successfully received for the reference test channel under specified circumstances. 3.1.16 Transient Phenomena A disturbance within a short time interval which cannot be distinguished as two consecutive stable conditions. 3.1.17 Vehicular Equipment A piece of equipment that is permanently installed on a vehicle and is powered by the vehicle's power supply system, or that is used on a vehicle and is equipped with a vehicle power adapter which is supported by the vehicle's power supply system. 3.1.18 Common-mode Absorption Device A device to be mounted on cables leading out of the radiated emission measurement test space to reduce compliance uncertainty. 3.2 Abbreviations For the purposes of this document, the following abbreviations apply. AC Alternating Current BWChannel Channel Bandwidth DC Direct Current ERP Ear Reference Point EUT Equipment Under Test e.r.p. effective radiated power FOOB The boundary between the NR out of band emission and spurious emission domains FUL_high The highest frequency of the uplink Channel bandwidth FUL_low The lowest frequency of the uplink Channel bandwidth FR Frequency range NR New Radio RB Resource Block RF Radio Frequency TCH Traffic Channel TPC Transmit Power Control UE User Equipment UTRA Universal Terrestrial Radio Access UT The rated voltage for the equipment 5G The Fifth Generation 4 Test Conditions 4.1 General Conditions The test shall be carried out under the conditions of normal operation of the equipment specified by the manufacturer, and the output power level of the UE shall be the level for maximum rated output power. The test configuration shall be as close as possible to typical conditions of actual use. When the UE has an integral antenna, the antenna in normal use shall be installed for the test, unless otherwise specified in this Part or the manufacturer declares that the antenna is removable. If the EUT is part of the system, or is connected to ancillary equipment, the test may be performed with the minimum configuration of the ancillary equipment, and the port connected to the ancillary equipment shall be activated. If the EUT has a large number of ports, a sufficient number of ports shall be selected to simulate actual operating conditions, and ensure that all different types of ports are included. The EUT ports that are connected to other equipment in actual use shall be connected to ancillary equipment, associated measurement equipment or a matched load that simulates the impedance of ancillary equipment during the test. For RF input/output ports, a matched load shall be terminated. The EUT ports that are not connected to other equipment in actual use, such as service ports, program ports or debugging ports, shall not be connected to other equipment during testing. If these ports are to be connected to ancillary test equipment in order to excite the EUT, or if the interconnecting cable must be extended, ensure that the evaluation of the EUT is not affected by the associated measurement equipment or the extension of the cable. The ancillary measurement equipment shall be placed outside the test area. If placed in the test area, the ancillary measurement equipment shall not affect the test results of the EUT, or its influence shall be excluded. If the EUT supports multiple operating modes, tests shall be performed in each operating mode. For example, the UE has two operating modes of voice service and data service, and both of them shall be tested. The disturbance measurement shall be carried out at the mode under which the EUT generates the maximum disturbance during normal operation. During radiation disturbance measurement, in order to measure the maximum radiation disturbance, some necessary measures may be taken, such as moving the cables of the EUT. The operating frequency range (FR) of the UE is shown in Table 1. For different operating frequency ranges, the test conditions for electromagnetic compatibility may be different.
