当终端设备在第二资源上发送第二信息与终端设备接收到第一信息存在对应关系时，第二信息包括的内容可以与终端设备接收到了第一信息没有任何对应关系，从而提高了终端设备发送第二信息的灵活性。

可选地，终端设备在第一资源上接收第一信息之前，该方法还包括：终端设备在第三资源上发送第四信息，该第四信息用于请求调度上行传输，其中，第三资源与所述第二资源相异。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1示出了一种适用本申请的通信系统100。该通信系统100包括网络设备110和终端设备120，网络设备110与终端设备120通过无线网络进行通信，当终端设备120发送 数据时，无线通信模块可对信息进行编码以用于传输，具体地，无线通信模块可获取要通过信道发送至网络设备110的一定数目的数据比特，这些数据比特例如是处理模块生成的、从其它设备接收的或者在存储模块中保存的数据比特。这些数据比特可包含在一个或多个传输块(也可称为信息块或数据块)中，传输块可被分段以产生多个编码块。
在本申请中，终端设备可称为接入终端、UE、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及5G移动通信系统中的用户设备。
网络设备可以是码分多址(code division multiple access，CDMA)系统中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站(node B，NB)，还可以是LTE系统中的演进型基站(evolutional node B，eNB)，还可以是5G移动通信系统中的基站(gNB)，上述基站仅是举例说明，网络设备还可以为中继站、接入点、车载设备、可穿戴设备以及其它类型的设备。
上述适用本申请的通信系统仅是举例说明，适用本申请的通信系统不限于此，例如，通信系统中包括的网络设备和终端设备的数量还可以是其它的数量。又例如，适用本申请的通信系统100还可以是设备到设备(device to device，D2D)通信系统，其中，网络设备110和终端设备120为D2D通信系统中进行通信的两个设备。
为了便于理解本申请，在介绍本申请提供的发送上行信息的方法前，首先对本申请涉及的概念做简要介绍。
图2示出了适用于本申请的一种发送上行信息的方法的示意图。图2中，0到9表示一个无线帧所包括的十个子帧，终端设备在子帧1向网络设备发送第一调度请求(该第一调度请求可以理解为调度请求的第一格式)，并在子帧5接收上行授权，该上行授权用于调度终端设备发送上行信道，随后终端设备在子帧9发送该上行信道。应理解，在本申请中，发送上行信道指的是通过该上行信道对应的传输资源发送上行信息，该传输资源可以是网络设备动态调度的，也可以是网络设备半静态配置的。
由图2可知，网络设备只有在子帧9接收到上行信息之后才能确定终端设备接收到上行授权，若网络设备在子帧9未接收到上行信息，则网络设备无法确定终端设备是否收到了上行授权，例如，当网络设备接收到的上行信息的信号强度小于强度阈值时，网络设备无法确定接收到的上行信息是否为该网络设备在子帧5调度的UE所发送的上行信息。
因此，网络设备只能在下个无线帧继续调度该终端设备重传上述上行信息，并且认为终端设备没有在子帧5上发送上行信息，从而导致了较大的时延。
为了减小图2所示的方法中的时延，并且为了提高上行信息的解码成功率，本申请提供了一种发送上行信息的方法，该方法的流程图如图3所示，方法300包括：
S310，终端设备在第一资源上接收第一信息，该第一信息用于指示上行传输资源，所述上行传输资源用于该终端设备发送第一信道。
S320，该终端设备在第二资源上发送第二信息，所述第二信息用于指示该终端设备已请求到所需要的上行传输资源。
应理解，终端设备作为方法300的执行主体(或称为“执行设备”)仅是举例说明。
S310中，第一信息例如可以是上行授权，该上行授权用于指示终端设备发送第一信 道，本申请对第一信息的具体名称以及第一信息的其它指示功能不作限定，例如，第一信息还可以指示终端设备在发送第一信道时的发射功率等参数。
终端设备接收第一信息的方式例如可以是终端设备接收第三信道，第三信道上携带了所述第一信息，本申请对终端设备接收第一信息的方式不做限定。
可选地，终端设备在第一资源上接收第一信息之前，该终端设备在第一资源上检测第一信息。可以理解的是，该终端设备可能接收第一信息，也可能没有接收到第一信息，即，在本申请中，接收到信息指的是检测到信息并且成功解码该信息。当该终端设备在第一资源上没有检测到第一信道之后，该终端设备一定没有接收到第一信息。可以理解的是，如终端设备没有接收到第一信息，终端设备无需发送显式信息指示网络设备所述终端设备没有接收到第一信息，进而终端设备无需发送显式信息指示网络设备所述终端设备没有已请求到所需要的上行传输资源，而网络设备可以根据是否接收到第二信息判断终端设备是否接收到第一信息，可以理解为，进而网络设备可以根据是否接收到第二信息判断终端设备是否已请求到所需要的上行传输资源，这样可以避免终端设备由于不知道网络设备会发送第一信息的确定时间，而导致终端设备频繁的发送显式信息指示所述终端设备没有接收到第一信息，从而可以为节约终端设备的电量。
在本申请中，有一种情况时虽然终端设备接收到了第一信息，由于终端设备的上行待传输数据量较大，第一信息指示的上行传输资源不能完全承载下。或者由于第一信息指示的上行传输资源并不适用于终端设备发送，如传输时间间隔分配的太长造成时延过大，传输时间间隔分配的太小造成终端设备没有办法正确传输等原因，从而造成第一信息指示的上行传输资源不能满足所述终端设备传输第一信道的需求时，终端设备可以通过第二信息告知网络设备，该终端设备没有申请到所需要的上行传输资源，网络设备接收到第二信息后，就可以立即再发送另一个信息分配更多的上行传输资源给所述终端设备，因此减少了数据传输的时延。
此外，在本申请中，发送信道(例如，发送第一信道)指的是通过该信道发送数据和/或控制信息。本申请中，第一信道和第二信道均为上行数据信道。
S320中，第二资源可以与第一资源相同，也可以与第一资源不同。在本申请中，如无特别说明，两个资源不同均指两个资源的除时域资源之外的资源相异，例如，第二资源与第一资源不同指的是：第二资源所包括的频域资源、码域资源和空域资源中的至少一种资源与第一资源中的对应资源相异。
当终端设备在第二资源上发送信息与终端设备接收到第一信息不存在对应关系时，第二信息包括的内容与终端设备接收到了第一信息存在对应关系。例如，第二信息包括专用字段或比特状态值，该专用字段或比特状态值用于指示终端设备收到了第一信息。
当终端设备在第二资源上发送信息与终端设备已请求到所需要的上行传输资源不存在对应关系时，第二信息包括的内容与终端设备已请求到所需要的上行传输资源存在对应关系。例如，第二信息包括专用字段或比特状态值，该专用字段或比特状态值用于指示终端设备收到了第一信息。
当终端设备在第二资源上发送信息与终端设备接收到第一信息存在对应关系时，第二信息包括的内容可以与终端设备接收到了第一信息没有任何对应关系。网络设备在第二资源上接收到第二信息时，即可确定终端设备接收到了第一信息，此时，第二信息可以用于 指示终端设备接收到了第一信息，也可以用于指示除“接收到第一信息”之外的其它内容，第二信息也可以是反馈信息或者调度请求，例如，第二信息也是用于请求调度上行传输资源，本申请对第二信息的具体形式不作限定。
当终端设备在第二资源上发送信息与终端设备已请求到所需要的上行传输资源存在对应关系时，第二信息包括的内容可以与终端设备已请求到所需要的上行传输资源没有任何对应关系。网络设备在第二资源上接收到第二信息时，即可确定终端设备接收到了第一信息，此时，第二信息可以用于指示终端设备已请求到所需要的上行传输资源，也可以用于指示除“已请求到所需要的上行传输资源”之外的其它内容，第二信息也可以是反馈信息或者调度请求，例如，第二信息也是用于请求调度上行传输资源，本申请对第二信息的具体形式不作限定。
第二信息可以通过多种方式指示该终端设备已请求到所需要的上行传输资源。例如，第二信息可以指示终端设备待发送第一信道(情况1)，或者，第二信息可以指示终端设备已发送第一信道(情况2)，或者，第二信息可以是已请求到所需要的上行传输资源(情况3)。
对于上述情况1，
第二信息的发送时间在发送第一信道的时间之前，例如，第二信息的发送时间可以是图2所示的子帧7或子帧8，若网络设备未在接收到第一信道之前接收到第二信息，则网络设备可以确定终端设备未收到上行授权，网络设备可以提前调度终端设备重传所述第一信道，从而，网络设备可以提前确定终端设备是否收到了上行授权，减小了上行传输的时延。
此外，若网络设备收到了第二信息后，网络设备无需通过第一信道的信号强度判断终端设备是否发送了第一信道，网络设备就可以在终端设备发送第一信道的资源上尝试接收所述第一信道，即网络设备可以尝试去解码所述第一信道。如果第一信道解码错误，则网络设备可以缓存该第一信道的信息并重传第一信息，待接收到第一信道的重传信息后将缓存的该第一信道的信息与第一信道的重传信息进行混合自动重传请求(hybrid automatic repeat request，HARQ)软信息合并解码，从而提高了上行信息的解码成功率。
情况1中，第二信息的发送时间可以是预先定义的，例如，网络设备在子帧5发送了第一信息后，即可确定在子帧7和子帧8检测第二信息，若网络设备未在子帧7和子帧8检测到第二信息，则网络设备可以确定终端设备未接收到第一信息，或未请求到所需要的上行传输资源。第二信息的发送时间也可以是第一信息中指示的，例如网络设备在子帧5发送了第一信息，该第一信息中指示了第二信息的发送时间为子帧9，即可确定在子帧9上检测第二信息，若网络设备未在子帧9检测到第二信息，则网络设备可以确定终端设备接收到第一信息，或确定终端设备已请求到所需要的上行传输资源。
对于上述情况2，
第二信息的发送时间在发送第一信道的时间之后。例如，网络设备无需通过第一信道的信号强度判断终端设备是否发送了第一信道，若网络设备在图2所示的子帧9接收到了信号强度小于强度阈值的信号(假设为第一信道的信号)，网络设备可以先缓存该信号的信息，当网络设备接收到情况2所述的第二信息时，网络设备可以先尝试将该缓存的信息进行解码，也可以是等待接收到第一信道的重传后将该缓存的信息与第一信道的重传的信 息进行HARQ软信息合并解码接收，从而提高了上行信息的解码成功率。
又例如，若网络设备在图2所示的子帧7未接收到情况1所述的第二信息，则网络设备可以认为终端设备未收到第一信息，或认为终端设备未请求到所需要的上行传输资源，并调度终端设备重传第一信道，当网络设备随后接收到情况2所述的第二信息时，则网络设备可以将第一信号的信息与接收到的重传信息进行HARQ软信息合并解码。
上述两个实施例均提高了上行信息的解码成功率。
对于上述情况3，
第二信息的发送时间可以在网络设备反馈其成功接收第一信道之前。由于第一信道承载信息的内容大小是由网络设备确定，实际中第一信道可能满足终端设备的需要，也可能不满足。因此，终端设备可以通过第二信息通知网络设备其需要的资源是否申请到。对比现有技术中终端设备只能在使用第一信道上报缓存器状态报告指示网络设备其待传数据大小，而通过本实施例，无需网络设备成功接收第一信道，就告知网络设备该终端设备其待传数据大小等信息，使得网络设备可以快速调度该终端设备，从而有效降低了数据传输的等待时间，可以减小上行传输的时延。
需要说明的是，网络设备反馈其成功接收第一信道可以是反馈肯定应答(acknowledge，ACK)，也可以是在该第一信道的HARQ进程上调度了初传。
对于上述情况1～3，
第二信息还可以是第二调度请求，此第二调度请求可以理解为调度请求的第二格式，也可以理解为与第一调度请求所占用的资源或携带的内容不同的调度请求，此第二调度请求用于指示终端设备请求网络设备调度上行传输。
当第二调度请求的发送时间在发送第一信道的时间之前时，网络设备可以根据是否接收到第二调度请求确定终端设备是否接收到第一信息，进而确定是否已请求到所需要的上行传输资源，从而可以减小上行传输的时延。
当第二调度请求的发送时间在发送第一信道的时间之后时，网络设备接收到调度请求之后，可以先尝试将缓存的第一信道的信息进行解码，也可以是等待接收到第一信道的重传后将缓存的该第一信道的信息与第一信道的重传的信息进行HARQ软信息合并解码接收，从而提高了上行信息的解码成功率。
终端设备可以根据实际情况选择发送第二调度请求的时间。例如，当终端设备在图2所示的子帧1发送了第一调度请求后，若在预先定义的资源上一直未检测到第一信息，则终端设备可以在子帧7或子帧8仍发送第一调度请求，网络设备接收到第一调度请求后即可确定终端设备未接收到第一信息，或确定终端设备没有请求到所需要的上行传输资源，从而可以快速重新发送第一信息，减小了上行传输的时延。又例如，终端设备可以在发送第一信道后发送第二调度请求，这样，当网络设备在接收到第二调度请求之后即可确定终端设备接收到第二信息，若此时网络设备存在情况2所述的问题，则可以提高上行信息的解码成功率。
可选地，终端设备在第二资源上发送第二信息之前，方法300还包括：
S301，所述终端设备根据第一对应关系确定第二资源，该第一对应关系为该第二资源与该第二信息的对应关系。
第二资源可以是时域资源、频域资源和码域资源中的至少一种资源，第一对应关系例 如可以是通信系统预先定义的，也可以是网络设备通过高层信令配置的，本申请对第一对应关系的配置方法不做限定。其中，码域资源可以是一个序列，也可以是一个或多个序列的组合。例如，第二资源的时域资源是周期为2毫秒(ms)的1个时隙时间长度，第二资源的频域资源是1个物理资源块，第二资源的码域资源是特定的序列组合。
第二信息在所述第二资源上传输。网络设备可以根据此第二资源上是否有传输，确定是否接收到第二信息。当网络设备检测此第二资源上有传输(检测的信号强度或序列相关峰值大于或等于阈值)时，网络设备确定接收第二信息。当网络设备没有检测此第二资源上有传输(检测的信号强度或序列相关峰值小于阈值)时，网络设备确定没有接收第二信息。
可选地，终端设备在第二资源上发送第二信息之前，方法300还包括：
S302，所述终端设备根据第三信息确定第二资源，该第三信息用于指示资源集合中的一个资源为所述第二资源，该资源集合包括至少两个资源。
本实施例中，第三信息可以是与第一信息属于同一个下行控制指示信息中的信息，也可以是与第一信息属于不同的下行控制指示信息。第一信息也可以包括第三信息。
需要说明的，该资源集合可以是通信系统预先定义的，也可以是网络设备通过高层信令配置的。可以理解的，该资源集合可以包含大于等于2的资源。例如，该资源集合包括{资源1，资源2，资源3，资源4}，第三信息用于指示四个资源中的一个资源为所述第二资源，所述资源1、资源2、资源3、资源4为预先定义的或者高层信令配置的，本发明不做限定。
可选地，终端设备在第一资源上接收第一信息之前，方法300还包括：
S303，所述终端设备在第三资源上发送第四信息，该第四信息用于请求调度上行传输，其中，该第三资源与第二资源相异。
本实施例中，第三资源与第二资源相异包括下列情况中的至少一种：
第三资源的频域资源与第二资源的频域资源相异，
第三资源的码域资源与第二资源的码域资源相异，
第三资源的空域资源与第二资源的空域资源相异。
在本实施例中，第二信息可以是终端设备发送的与第四信息不同的一个信息，只要网络设备在于第三资源不同的资源上接收到了该终端设备发送的信息，即可确定该终端设备接收到了第一信息，从而提高了终端设备发送第二信息的灵活性。相应的，只要网络设备在于第三资源上接收到了该终端设备发送的信息，即可确定该终端设备没有接收到了第一信息，从而提高了减少了上行传输的时延。例如第四信息是第一调度请求，第二信息是第二调度请求，第一调度请求和第二调度请求所占用的资源相异。
可选地，第一资源的起始时间与第二资源的起始时间的差值的绝对值大于或等于第一时间阈值，该第一时间阈值为大于或等于零的数值。
第一时间阈值可以是通信系统预先定义的，也可以是网络设备通过高层信令配置的，还可以是网络设备和终端设备通过其它信息或者人工配置的方式确定的。作为一个可选的示例，第一时间阈值可以是终端设备接收第一信息、处理第一信息以及发送第二信息所需的最短时间，也可以是终端设备接收第一信息、处理第一信息、确定是否请求到需要的上行传输资源以及发送第二信息所需的最短时间，网络设备在第一资源的起始时刻开始计 时，待第一时间阈值过后开始在第二资源上检测终端设备可能发送的第二信息，从而可以避免网络设备长时间检测第二信息导致的能耗较大和处理器负担较重的问题。
可以理解的是，第一资源与第二资源的时域资源索引差值的绝对值为所述第一时间阈值与最大上行传输调整量(timing advance，TA)的值之和。
可选地，第一资源的终止时间与第二资源的起始时间的差值的绝对值大于或等于第三时间阈值，该第三时间阈值为大于或等于零的数值。
可以理解的是，第一资源与第二资源的时域资源索引差值的绝对值为所述第三时间阈值、最大上行传输调整量的值与一个时域资源的值之和。时域资源可以是TTI，也可以是一个或多个符号，也可以是一个或多个时隙，也可以是一个或多个子帧。例如第二资源的时域资源索引为时隙10，第一资源的时域资源索引为时隙0，那么所述第三时间阈值、最大上行传输调整量的值与一个时域资源的值之和为10个时隙。
可选地，第一资源的起始时间与第二资源的终止时间的差值的绝对值小于或等于第二时间阈值，该第二时间阈值为大于或等于零的数值。
第二时间阈值可以是通信系统预先定义的，也可以是网络设备通过高层信息配置的，还可以是网络设备和终端设备通过其他信息或者人工配置的方式确定的。第二时间阈值的值大于或等于第一时间阈值的值。作为一个可选的示例，第二时间阈值可以是网络设备等待终端设备发送第二信息的时间的最大值，网络设备在第一资源的起始时刻开始计时，若第二时间阈值过后仍未在第二资源上检测到第二信息，则可以认为终端设备未接收到第一信息，也可以认为终端设备未请求到所需要的上行传输资源，从而可以避免网络设备长时间检测第二信息导致的能耗较大和处理器负担较重的问题。
可选地，第一资源的终止时间与第二资源的终止时间的差值的绝对值小于或等于第四时间阈值，该第四时间阈值为大于或等于零的数值。
可选地，终端设备在第一资源上接收第一信息之前，方法300还包括：
S304，该终端设备生成所述第二信息。
终端设备可以在接收第一信息前生成第二信息，例如，终端设备可以在发送完调度请求或第四信息之后开始对第二信息进行编码、调制和速率匹配，若终端设备接收到了第一信息或终端设备已请求到所需要的上行传输资源，则可以及时通过发送第二信息通知网络设备该终端设备接收到了第一信息或终端设备已请求到所需要的上行传输资源；若终端设备在预设的时间未接收到第一信息或未请求到所需要的上行传输资源，则可以通过发送第四信息或调度请求及时隐式通知网络设备该终端设备未接收到第一信息或未请求到所需要的上行传输资源，以便于网络设备快速重传上行授权。
上文从终端设备的角度详细介绍了本申请提供的发送上行信息的方法，下面，将从网络设备的角度介绍本申请提供的接收上行信息的方法。
图4示出了本申请提供的一种接收上行信息的方法，该方法400包括：
S410，网络设备在第一资源上发送第一信息，该第一信息用于指示上行传输资源，所述上行传输资源用于终端设备发送第一信道。
S420，该网络设备在第二资源上检测第二信息，该第二信息用于指示该终端设备已请求到所需要的上行传输资源。
应理解，网络设备作为方法400的执行主体(或称为“执行设备”)仅是举例说明，方 法400的执行主体还可以是其它类型的网络设备。S410中的终端设备也是举例说明。
网络设备可以在接收到终端设备发送的调度请求之后向该终端设备发送第一信息，第一信息用于调度终端设备进行上行传输，随后网络设备在第二资源上检测请求到所需要的上行传输资源的确认信息，即，第二信息。网络设备在第二资源上检测第一信息的确认信息，可以是第二信息。
回到图2，假设第一资源对应的时域资源为子帧5，第一信息指示的发送第一信道的时间是子帧9，
若网络设备在子帧5至子帧9之间的时段内(不包括子帧5和子帧9)检测到并成功解码了第二信息，则网络设备可以确定终端设备接收到了第一信息或终端设备已请求到所需要的上行传输资源，网络设备可以继续等待接收第一信道；
若网络设备在子帧5至子帧9之间的时段内(不包括子帧5和子帧9)未检测到第二信息，且在子帧9没有检测到第一信道(假设第一信道的信号强度未达到强度阈值)，且在子帧9之后检测到并成功解码了第二信息，则网络设备可以尝试将缓存的子帧9上发送第一信道的资源上的信息进行解码；
若网络设备在子帧5至子帧9之间的时段内(不包括子帧5和子帧9)未检测到第二信息，则网络设备可以向终端设备重传第一信息，重传的第一信息用于指示终端设备重传第一信道，当网络设备在子帧9没有成功接收第一信道，且在子帧9之后检测到并成功解码了第二信息，则网络设备可以将缓存的第一信道的信息与接收到的第一信道的重传的信息进行合并解码。
因此，本申请提供的接收上行信息的方法400，网络设备可以在接收第一信道前确定终端设备是否接收到了第一信息或终端设备是否已请求到所需要的上行传输资源，并根据对第二信息的接收结果采取如上所述的不同的处理方式，从而可以减小上行传输的时延，并提高上行传输的可靠性。
本领域技术人员可以清楚地了解到：在方法400中，网络设备和终端设备均可等同于方法300中的网络设备和终端设备，且网络设备和终端设备的动作与方法300中的网络设备和终端设备的动作相对应，为了简洁，在此不再赘述。
可选地，网络设备在第二资源上检测第二信息之前，方法400还包括：
S401，该网络设备根据第一对应关系确定所述第二资源，其中，所述第一对应关系为所述第二资源与所述第二信息的对应关系。
第二资源可以是时域资源、频域资源和码域资源中的至少一种资源，第一对应关系例如可以是通信系统定义的，也可以是网络设备通过高层信令配置的，本申请对第一对应关系的配置方法不做限定。
可选地，网络设备在第二资源上检测第二信息之前，方法400还包括：
S402，该网络设备发送第三信息，该第三信息用于指示资源集合中的一个资源为该第二资源，该资源集合包括至少两个资源。
本实施例中，第三信息例如可以是与第一信息位于同一个数据包中的信息，资源集合可以是通信系统定义的，也可以是网络设备通过高层信令配置的。
可选地，网络设备在第一资源上向终端设备发送第一信息之前，方法400还包括：
S403，该网络设备在第三资源上接收第四信息，该第四信息用于请求调度上行传输， 其中，该第三资源与第二资源相异。
本实施例中，第三资源与第二资源相异包括下列情况中的至少一种：
第三资源的频域资源与第二资源的频域资源相异，
第三资源的码域资源与第二资源的码域资源相异，
第三资源的空域资源与第二资源的空域资源相异。
在本实施例中，第二信息可以是终端设备发送的与第四信息不同的一个信息，只要网络设备在与第三资源不同的资源上接收到了该终端设备发送的信息，即可确定该终端设备接收到了第一信息或终端设备已请求到所需要的上行传输资源，从而提高了网络设备接收第二信息的灵活性。
可选地，第一资源的起始时间与第二资源的起始时间的差值的绝对值大于或等于第一时间阈值，所述第一时间阈值为大于或等于零的数值。
从而可以避免网络设备长时间检测第二信息导致的能耗较大和处理器负担较重的问题。
可选地，第一资源的起始时间与第二资源的终止时间的差值的绝对值小于或等于第二时间阈值，所述第二时间阈值为大于或等于零的数值。
从而可以避免网络设备长时间检测第二信息导致的能耗较大和处理器负担较重的问题。
可选地，方法400还包括：
S430，网络设备在第四资源上发送第五信息，该第五信息用于指示终端设备发送第二信道，该第二信道为第一信道的重传。
以图2为例，若网络设备在子帧7未收到第二信息，则可以在子帧8(即，第四资源包括的时域资源)上发送第五信息，从而可以及时调度终端设备重传第一信道，减小了上行传输的时延。
若网络设备在子帧7收到了第二信息，但在子帧9没有成功解码第一信道，则网络设备也可以在子帧9之后向终端设备发送第五信息，以便于将该第一信道与第二信道进行HARQ软信息合并解码，从而可以提高上行传输的可靠性。
此外，若网络设备既没有接收到第二信息，又没有接收到第一信道，则网络设备也可以向终端设备发送第五信息。
可选地，方法400还包括：
S440，网络设备将第一信道与第二信道进行合并解码，其中，该网络设备在第二资源上检测到所述第二信息，或者，该网络设备检测到所述第一信道；或，
该网络设备将该第二信道单独进行解码，其中，该网络设备在该第二资源上未检测到该第二信息且该网络设备未检测到该第一信道。
仍以图2为例，子帧9是第一信息指示的用于传输第一信道的时域资源，若网络设备在子帧6、子帧7或子帧8收到了第二信息，尝试将第一信道单独进行解码，若解码不成功，网络设备再向终端设备发送第五信息，待接收到重传的第一信道后，将缓存的第一信道与重传的第一信道进行合并解码；网络设备也可以在接收到第一信道后不进行单独解码，而是直接向终端设备发送第五信息，以便于及时进行解码成功概率更高的合并解码。上述合并解码例如可以是HARQ软信息合并解码，也可以是HARQ调制前信息合并解码， 也可以是信号直接叠加合并解码。从而，本实施例可以提高上行传输的可靠性。
S440中，“网络设备检测到所述第一信道”指的是网络设备检测到第一信道(第一信道的信号强度大于或等于强度阈值)但网络设备没有成功解码第一信道，网络设备可以缓存该第一信道以便于进行合并解码。网络设备可以根据下述方法确定第一信道是否成功解码，将解码后的第一信道的循环冗余校验(cyclic redundancy check，CRC)与预先定义的CRC进行比对，如果二者相异，则认为没有成功解码第一信道；如果二者相同，则认为解码第一信道。CRC大于等于4位比特序列。
若网络设备既未接收到第二信息，又未检测到第一信道，网络设备在此情况下无法判断终端是否发送了第一信道，因此，网络设备需要将第二信道单独进行解码。
