与LTE一样,NR的RB(Resource Block)也是由频域上12个连续的子载波组成,由于NR在同一个载波上支持多个参数集,不同参数集的RB在频域上所占的带宽是不同的,为了保证不同参数集的RB对齐,NR引入Point A、虚拟资源块VRB(Virtual Resource Block),公共资源块CRB(Common Resource Block)、物理资源块PRB(Physical ...
REG(Resource-element group):资源元素组 RIM(Remote interference management):远程干扰管理 RIM-RS(Remote interference management reference signal):远程干扰管理参考信号 SRS(Sounding reference signal):探测参考信号--上行 SSS(Secondary synchronization signal):二次同步信号--下行 VRB(Virtual resource block):虚拟...
SSS(Secondary synchronization signal): 二次同步信号--下行 VRB(Virtual resource block): 虚拟资源块。
Mapping to VRB (Virtual Resource Block): The data is mapped to virtual resource blocks within the frequency domain. Mapping from VRB to PRB (Physical Resource Block): The virtual resource blocks are then mapped to physical resource blocks for actual transmission.Each...
This step is the process that maps (converts) the virtual resource block(resource grid) into physical resource block(resource grid). Two different types of mappings are supported in 5G as described below. Non-Interleaved Mapping: In non-interleaved mapping, the modulated and precoded symbols are...
RB(Resource Block)–资源块 切片在接入网、承载网、核心网分别用什么技术? 接入网:QoS调度(软切)、RB资源预留(硬切)和独立载波(硬切)。 承载网:VPN+QoS、以太独立端口和Flex-E。 核心网:根据核心网网元部署方式,可分为完全共享、部分共享和完全独立三种模式。
eMTC增强:支持更大的TBS(Transport Block Size,传输快大小)和14个HARQ进程,提高半双工FDD终端的数据速率;通过PUSCH子PRB(Physical Resource Block,物理资源块)资源分配,支持终端功率增强;增加可选终端功能,半双工FDD终端支持1736比特最大下行TBS。 NB-IoT增强:支持上行和下行单播16-QAM,与Rel-16 NB-IoT相比增加下行...
Figure 2: Scalable OFDM numerology for NR The spectrum of OFDM signal decays rather slowly outside the transmission bandwidth. In order to limit out-of-band emission, the spectrum utilization for LTE is 90 percent. That is, 100 of the 111 possible physical resource blocks (PRBs)...
与4G(LTE)相同,在5G(NR)网络中RRC重配置(RRCReconfiguration)是终端与网络之间建立无线连接很重要的步骤1.RRC重配置步骤RRC重配置(RRCReconfiguration)是在终端(UE)完成接入流程之后,根据其能力和网络资源为其进行无线资源分配的过程;具体流程如下:2.RRC重配置内容...
