本申请实施例提供的信号传输方法，网络侧设备只能在实际信道带宽内发送第二下行信号和/或接收第二上行信号，不允许网络侧设备发送的第二下行信号和/或接收的第二上行信号的频域资源超出实际信道带宽的范围，以提高终端对第二下行信号的解调性能或者提高网络侧设备对第二上行信号的解调性能。
可选地，所述实际信道带宽是可变的。
示例地，实际信道带宽的大小可以半静态的变化或者动态的变化，其中，实际信道带宽的可变可以体现在时间维度，即半静态的变化可以是每隔第一预设时间变化一次，动态的变化可以是每隔第二预设时间变化一次，其中，第一预设时间远大于第二预设时间；另外，实际信道带宽的可变还可以体现在通知维度，即半静态的变化可以为基于高层信令发送实际信道带宽，动态的变化可以为基于动态信令发送实际信道带宽。
另外，由于频谱带宽是任意的，但现有通信网络的协议仅支持规定的几种信道带宽和对应的同步栅格，并不支持任意信道带宽和任意同步栅格，而本申请定义的实际信道带宽可以是任意信道带宽，并可以定义新的同步栅格或者对现有同步栅格进行分组，所以采用本申请的信号传输方法可以减少引入新的信道带宽和同步栅格的复杂度，减少对网络的调度和配置限制。
