步骤21，在一个或多个候选时频域资源上，发送系统信息块。
可以理解的是，由于太赫兹频段的传播损耗比较严重，而且传输距离的微小变化就会极大地影响其信道的大尺度传输特性，进而导致不同距离的终端设备的可用带宽不同。本公开中，可以为系统信息块分配多个候选时频域资源，之后在多个候选时频域资源，同时向终端设备发送系统信息块，由此，即使太赫兹通信中有不可用带宽，终端设备也可以接收到网络设备发送的系统信息块，从而基于接收到的系统信息块对应的信道资源，进行信息的传输。
可选的，不同的候选时频域资源可以分布在不同的子带subband中。一个子带中可以包含M个资源块(resource block，RB)，一个RB中可以包含N个正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)子载波，其中，M和N分别为正整数。
其中，M的数值与N的数值可以相同，也可以不同，本公开对此不做限定。
可选的，网络设备在多个候选时频域资源上，发送的系统信息块可以相同，也可以不同，本公开对此不做限定。
可选的，系统信息块可以包括以下任一项：下行同步信号，系统信息及系统信息的解调参考信号。
可选的，每个系统信息块可以满足以下至少一项：

每个系统信息块对应多个上行控制信道的时频域资源。
可选的，若终端设备接收的系统信号块对应多个随机接入信道的时频域资源，则终端设备可以基于系统信号块中包含的任一随机接入信道的时频域资源进行随机接入。或者，终端设备接收的系统信号块对应多个上行控制信道的时频域资源，则终端设备可以基于系统信号块中包含的任一上行控制信道的时频域资源进行上行数据传输，本公开对此不做限定。
可以理解的是，网络设备可以先向终端设备发送系统信息块，若终端设备接收到系统信息块，则终端设备可以在接收到系统信息块之后的一段时间内，基于系统信息块中包含的信道资源，进行随机接入，或者发送上行数据。
通过实施本公开实施例，网络设备通过在一个或多个候选时频域资源上，向终端设备发送系统信息块，从而，使得多个候选时频域资源中即使有不可用带宽，终端设备也可以接收到网络设备发送的系统信息块，进而基于接收到的系统信息块与网络设备进行信息的传输，从而保证了信息传输的可靠性。
请参见图3，图3是本公开实施例提供的一种信息的传输方法的流程示意图,该方法由网络设备执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，根据协议约定，确定一个或多个候选时频域资源。
可以理解的是，由于太赫兹频段的传播损耗比较严重，传输距离的微小变化会极大的影响信道的传 输特性，即不同距离的终端设备对应的可用带宽不同。因此，本公开中，可以通过协议约定，将频域资源分为多个子带，然后规定系统信息块对应的多个候选时频域资源，且保证系统信息块在每个子带上都有对应的候选时频域资源。从而使得无论终端设备与网络设备间的距离如何变化，只要网络设备基于多个候选时频域资源发送系统信息块时，终端设备一定可以从至少一个子带中的候选时频域资源上接收到系统信息块。
步骤32，在一个或多个候选时频域资源上，发送系统信息块。

另外，若网络设备在多个候选时频域资源上分时发送系统信息块，相应的，终端设备可以在多个候选时频域资源上分时进行系统信息块的接收，当前接收到的系统信息块的质量较好，则终端设备即可根据系统信息块中包含的信道信息，进行上行数据传输或随机接入，从而不仅可以及时地向网络设备发送信息，而且节省了信道资源。
可以理解的是，若网络设备在一个候选时频域资源上分时发送系统信息块，则终端设备与网络设备间的距离与该候选视频域资源匹配时，终端设备即接收到该系统信息块，进而即可基于该候选时频域资源与网络设备进行信息传输。

可以理解的是，若网络设备在多个候选时频域资源上同时发送系统信息块，相应的，终端设备可以基于多个候选时频域资源同时接收多个系统信息块，从而可以至少在一个候选时频域资源上接收到系统信息块。进而即可根据接收的多个系统信息块，确定可用的时频域资源，由此，既保证了信息的可靠传输，又缩短了网络设备与终端设备进行信息传输的时间。
另外，若网络设备在多个候选时频域资源上分时发送系统信息块，相应的，终端设备可以在多个候选时频域资源上分时进行系统信息块的接收，若当前接收到的系统信息块的质量较好，则终端设备即可根据系统信息块中包含的信道信息，进行上行数据传输或随机接入，从而不仅可以及时地向网络设备发送信息，而且节省了信道资源。

可以理解的是，终端设备可以先基于候选时频域资源，接收系统信号块，之后确定接收的系统信号块的信号质量，在系统信息块的信号质量大于预设条件的情况下，确定终端设备待使用的时频域资源，进而基于待使用的时频域资源，向网络设备发送上行数据，从而保证了信息传输的可靠性。
可选的，终端设备可以将信号质量满足预设条件的系统信息块对应的随机接入信道的时频域资源，确定为待使用的随机接入信道的时频域资源。
