GNR射频指标发射部分释义(4)

UTRAACLR is specified for the first adjacent UTRA channel (UTRAACLR1) which center frequency is ± 2.5 MHz from NR channel edge and for the 2nd adjacent UTRA channel (UTRAACLR2) which center frequency is ± 7.5 MHz from NR channel edge.
和LTE类似，5G NR也有相应的对UMTS（WCDMA和TD-SCDMA）的邻道干扰的指标，ACLR1指的是5G信道边缘±2.5 MHz，ACLR2指的是5G信道边缘±7.5 MHz。
UTRA ACLR
指标要求如下：
UTRA ACLR
6.5.3 Spurious emissions发射杂散
这里的发射杂散是通用的发射杂散，和LTE的要求非常类似，是out of band emssions之外的频谱要求。具体指标要求如下：
发射杂散
6.5.4 Transmit intermodulation 发射交调
The transmit intermodulation performance is a measure of the capability of the transmitter to inhibit the generation of signals in its non linear elements caused by presence of the wanted signal and an interfering signal reaching the transmitter via the antenna.
UE transmit intermodulation is defined by the ratio of the mean power of the wanted signal to the mean power of the intermodulation product when an interfering CW signal is added at a level below the wanted signal at each transmitter antenna port with the other antenna port(s) if any terminated. Both the wanted signal power and the intermodulation product power are measured through NR rectangular filter with measurement bandwidth shown in Table 6.5.4-1.
The requirement of transmit intermodulation is specified in Table 6.5.4-1.
发射交调反映的是天线口的非线性特性，分别在中心频点±信道带宽和2*信道带宽加注-40dBC的CW信号，测试交调产物分别不超过-29dBc和-35dBC。
