In NR 5G, the three types of CSI-RS based reference signal measurements, as defined in TS 38.215 Sections 5.1.2 and 5.1.4, includes: CSI-RSRP (CSI reference signal received power): CSI-RSRP is defined as the linear average over the power contributions of the resource elements of the ante...

所以，UE使用哪张表进行CQI上报，是通过cqi-Table参数决定的，而最主要的已经就是误块率，NR网络定义3张CQI表的目的就是为了最大限度的提升编码效能。如果UE没有配置timeRestrictionForChannelMeasurements参数，则UE应仅基于NZP CSI-RS导出用于计算上行链路时隙n中报告的CSI值的信道测量值，不迟于与CSI资源设置相关联...
一、5G终端测量配置3GPP在TS38.331第5.5节进行了定义。5G(NR)中的测量配置基线类似于4G(LTE),其中测量(UE)在RRC_CONNECTED中执行的测量至少分为三种测量类型:–---同频5G(NR)测量; ---频率间5G(NR)测量; –---4G(E-UTRAN)的RAT间测量。 *从R15...
CSI-RS不是5GNR中的新概念。尽管在5GNR规范的细节有所不同,但出于相同目的,它们早已在LTE中使用。CSI-RS是在带内传输的。它有助于波束赋形、干扰估计和CoMP(协调的多点传输)。附带说明一下,CSI-RS有一种称为TRS(跟踪参考信号)的子类型,不要与PTRS(相位跟踪参考信号)混淆,它们的目标和特性略有不同。我们...
In 5G NR, RSRP measurement is performed and reported atLayer 1(Physical Layer) andLayer 3(RRC Layer). For example, 5G capable device can provideSS-RSRPmeasurements atLayer 1when sending Channel State Information(CSI)and at Layer 3 when sending anRRC: Measurement Reportto gNB. ...
