GNR射频指标发射部分释义(3)
2023-04-08 来源:文库网
The average of the basic in-band emission measurement over 10 sub-frames shall not exceed the values specified in Table 6.4.2.3-1.
带内杂散定义为,12个子载波0RB的功率和满RB的功率之比,这个指标反映的是分配部分RB的时候对带内其他RB资源的干扰情况,因为都是分配带宽内,故称为带内杂散。
inband emissions
6.5 Output RF spectrum emissions输出射频发射频谱
6.5.1 Occupied bandwidth占用带宽
Occupied bandwidth is defined as the bandwidth containing 99 % of the total integrated mean power of the transmitted spectrum on the assigned channel. The occupied bandwidth for all transmission bandwidth configurations (Resources Blocks) shall be less than the channel bandwidth specified in Table 6.5.1-1.
占用带宽,在我们绝大多数系统里都是99%的功率分布的带宽,这点和LTE没有任何区别。
占用带宽
6.5.2 Out of band emission带外杂散
The Out of band emissions are unwanted emissions immediately outside the assigned channel bandwidth resulting from the modulation process and non-linearity in the transmitter but excluding spurious emissions. This out of band emission limit is specified in terms of a spectrum emission mask and an adjacent channel leakage power ratio. 带外杂散包含SEM和ACLR两部分,其中SEM单位是绝对值dBm,而ACLR单位是相对值dBC。

6.5.2.2 Spectrum emission mask 发射频谱模板
The spectrum emission mask of the UE applies to frequencies (ΔfOOB) starting from the edge of the
assigned NR channel bandwidth. For frequencies offset greater than FOOB。
发射频谱模板指的是channel bandwidth到ΔfOOB之间的频谱,见上面的图片SEM部分。
SEM测试要求
6.5.2.4 Adjacent channel leakage ratio临道功率泄露
Adjacent channel leakage power Ratio (ACLR) is the ratio of the filtered mean power centred on the assigned channel frequency to the filtered mean power centred on an adjacent channel frequency.
ACLR指的是指定的信道对相邻的信道滤波后的平均功率之比,这个参数的好坏反映的当前终端对同系统的其他用户的影响。
6.5.2.4.1 NR ACLR 5G NR临道功率泄露
5G NR的ACLR要求
6.5.2.4.2 UTRA ACLR UMTS制式临道功率泄露
UTRA adjacent channel leakage power ratio (UTRAACLR) is the ratio of the filtered mean power centred on the assigned NR channel frequency to the filtered mean power centred on an adjacent(s) UTRA channel frequency.
