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...

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. How Measurement ...

如刚刚提到的，UE通过测量CSI-RS信号来确定合适的预编码矩阵，然后把使用这个预编码矩阵用于发射SRS信号（探测参考信号）。之后，gNB通知UE使用波束赋形矢量的哪个子集。最后，UE可以将选择的波束赋形矢量用于PUSCH传输。总之，在该模式下，尽管UE推荐了一个预编码矩阵，但gNB仍然可以否决某些波束成形向量，并且可能减少...
5G NR RSRQ | SS-RSRQ, CSI-RSRQ •SS-RSRQstands for Secondary synchronization Signal Reference Signal Received Quality. • It is defined as ratio of N x SS-RSRP/NR carrier RSSI. Here N refers to number of resource blocks in NR carrier RSSI measurement Bandwidth. The measurements in N ...

5G NRhas introduced SSB based measurement timing configuration also known asSMTC. The SMTC defines a duration and periodicity that can be used to restrict the UE measurement on the certain resources. WithinSMTC periodand on the configured SSB and/or CSI-RS, UE will conduct the Radio Link ...
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...
