其中，无线通信系统的时域资源由多个帧(Frame)组成，每个帧由10个子帧(Subframe)组成，子帧索引号为0～9。一个subframe的时域长度为1ms，对应30720个时域采样间隔，其中时域采样间隔Ts＝32.55ns。下行到上行的切换周期为5ms，即表示10ms或1个Frame内存在2次从下行子帧到上行子帧的切换；下行到上行的切换周期为10ms，即表示10ms或1个Frame内存在1次从下行子帧到上行子帧的切换。D表示下行子帧，U表示上行子帧，S表示特殊子帧。特殊子帧由3部分构成，下行导频时隙(Downlink Pilot Time Slot，DwPTS)、保护周期(Guard Period，GP)、上行导频时隙(Uplink Pilot Time Slot，UpPTS)。

SG2、SG4、SG6占用的子载波索引与SG0占用的子载波索引相同，或者SG2、SG4、SG6占用的子载波索引与SG0占用的子载波索引相差Delta。其中，SG2、SG4、SG6对应的Delta取值可变。Delta的取值可以由以下至少之一确定：
小区索引(Cell ID)；
SG2、SG4、SG6的时域起始位置，例如帧索引、子帧索引等。
