1、为终端(UE)进行5G资源分配的S1IV#5G#UE#PDSCU#PUSCH#S1IV5G(NR)网络中为每个终端(UE)调度的资源不仅包括时隙(TS),还有时隙内的符号(OFDM)；*4G(1TE)网络中的资源仅是子帧级别的调度。在5G(NR)网络中通过DCI调度时，终端根据PDSCH中DC1分配的字段值m,按照分配表提供行索引m+1去接收(发送)数据。其索引行定义了为终端(UE)分配的时隙偏移量K0、起始和长度指示符S11V；也可以直接定义起始符号S和分配长度1及在PDSCH接收中假定的PDSCH映射类型。一、终端起始分配符号和长度S1IV(Startand1engthIndiCator)

2、是网络为终端在PDSCH时域上分配的起始和长度指示。S11V中还定义了使用SingIeNUmber分配PDSCH起始符号和连续的符号数量。通常S1IV中包括两个数量:起始符号S和长度1o根据TS38.2145.1.2.1定义S1IV中为终端分配的起始符号和连续符号数计算公式如下：if(1-I)=7thenS1IV=14x(1-1)+S除非S1IV=14x(14-1+1)+(14-1-S)此处OV1V=14-SS=StartSymbo1IndeX(起始符号指示)1=NumberofConsecutiveSymbo1s(连续符号数)1.1 R15版本分配表根据该公式可创建一个包含可能S和1值的大表
