请参阅图2所示，为本申请实施例提供的网络设备和终端设备之间的一种交互流程示意图，本申请实施例提供的信息传输的方法，主要包括如下步骤。
201、网络设备确定为终端设备分配资源块或者子载波资源。
在本申请实施例中，网络设备为终端设备进行资源分配时可以分配资源块，即以最小单位为1个资源块进行资源分配，网络设备还可以为终端设备分配子载波资源，即以最小单位为1子载波进行资源分配。例如网络设备可以根据当前网络负载确定以资源块或者子载波资源为单位进行资源分配。举例说明，在本发明实施例中，网络设备使用下行控制信息(Downlink Control Information，DCI)格式6-0A对物理上行共享信道(Physical Uplink Shared channel，PUSCH)进行资源分配时，最小单位可以是1个资源块，并且也能够支持分配小于12个子载波的资源，因此提高了PUSCH的频谱效率。
202、网络设备确定下行控制信息，其中下行控制信息包含资源分配字段，资源分配字段用于指示所述分配的资源块或子载波资源。
在本申请实施例中，网络设备为终端设备进行资源分配时可以采用资源块为单位，也可以采用子载波为单位，网络设备可以通过下行控制信息包含的资源分配字段来指示具体的资源分配情况。
其中，资源分配字段用于指示所述分配的资源块时，资源分配字段包括高

中的低

比特指示窄带索引，资源分配字段包括低比特是低M比特，用于指示窄带内的资源分配，其中，窄带是指频域上六个非重叠的连续物理资源块。M的取值可以为5或者3，X可以为0或更大的整数，具体结合应用场景来确定M和X的取值。资源分配字段所指示的资源块的数目大于或等于1，即资源分配以资源块为单位资源块。
资源分配字段用于指示所述分配的子载波资源时，资源分配字段包含高
Figure PCTCN2018083623-appb-000036
个比特和低L比特，高
Figure PCTCN2018083623-appb-000037
个比特指示窄带索引，低L比特指示K个资源块内的子载波资源的分配，且资源分配字段所指示子载波个数小于12。通常情况下，1个资源块包括12个子载波，本申请实施例中资源分配字段所指示子载波个数小于12，即资源分配以子载波为单位资源块资源块，因此可以分配更少的资源。该L可以是等于M+X。低L比特指示K个资源块内的子载波资源的分配，此时的K个资源块为网络设备配置的资源块或者预设的资源块，从而通过低L个比特，网络设备可以向终端设备指示所分配的子载波资源。
203、网络设备向终端设备发送下行控制信息。
其中，网络设备确定下行控制信息之后，网络设备可以向终端设备发送下行控制信息，该下行控制信息包含资源分配字段，资源分配字段指示了分配给终端设备的资源块或者子载波资源。
204、终端设备接收网络设备发送的下行控制信息，其中下行控制信息包含资源分配字段。
终端设备首先接收网络设备发送的下行控制信息，从该下行控制信息中确定出资源分配字段。
205、终端设备根据下行控制信息确定分配的资源。
206、在分配的资源上发送信息。
在本发明实施例中，终端设备通过资源分配字段可以确定网络设备以资源块为单位进行资源分配，或者以子载波资源为单位进行资源分配，并通过资源分配字段包括的高比特的状态和低比特的状态确定出分配给的资源，终端设备可以在网络设备分配的资源完成上行信息的发送。
207、网络设备在下行控制信息确定的资源上接收终端设备发送的信息。
在本申请实施例中，网络设备在分配给终端设备的资源上检测终端设备发送的信息，终端设备发送的信息可以使用网络设备分配的资源块或者子载波资源，具体取决于网络设备对资源的配置情况。
通过前述实施例对本申请的举例说明可知，网络设备通过资源分配字段包括的比特状态的取值不同来指示为终端设备分配资源块或者子载波资源，资源分配字段用于指示所述分配的资源块时，资源分配字段包括高
