需要说明的是，所述对第一上行数据进行重传，可以是指向网络侧设备重新传输或者说重新发送所述第一上行数据，以增加网络侧设备成功接收到所述第一上行数据的机率，增加终端与网络侧设备之间的数据传输的可靠性。
本申请实施例中，所述第一上行数据发送失败通过如下任意一项确认：
在预设时间内未接收到所述网络侧设备发送的反馈信息；
接收到所述网络侧设备发送的接收失败指示信息。
在一种实施方式中，终端在向网络侧设备发送第一上行数据后，若在预设时间内未接收到所述网络侧设备发送的反馈信息，则终端可以确认或者说判定所述第一上行数据发送失败。例如，终端发送第一上行数据后启动定时器(如pur-ResponseWindowTimer)，在该定时器运行期间，终端都没有接收 到网络侧设备发送的对于该第一上行数据的接收反馈，则确认所述第一上行数据发送失败，或者，也可以是确认pur-ResponseWindowTimer超时。
在另一种实施方式中，终端在向网络侧设备发送第一上行数据后，若接收到网络侧设备发送的接收失败指示信息，则也可以确认所述第一上行数据发送失败。例如，终端可以是通过混合自动重传请求(Hybrid automatic repeat request，HARQ)进程-1发送第一上行数据后启动定时器(如pur-ResponseWindowTimer)，在该定时器运行期间，若终端接收到网络侧设备发送的对于该第一上行数据的接收反馈为接收失败，如接收到关于HARQ进程-1的接收反馈为否定确认NACK，或者，接收到网络侧设备通过下行控制信息(Downlink Control Information，DCI)指示终端通过HARQ进程-1发送新数据，则终端确认所述第一上行数据发送失败。
本申请实施例中，终端向网络侧设备发送第一上行数据，在确认第一上行数据发送失败的情况下，可以对所述第一上行数据进行重传。这样，终端在数据传输失败的情况下，并不会放弃该数据的传输，而是能够对传输失败的数据进行重传，避免数据的丢失，增加了网络侧设备对数据接收成功的机率，确保终端与网络侧设备之间的数据交互的顺畅。
可选的，所述对所述第一上行数据进行重传包括：在满足第一预设条件的情况下，对所述第一上行数据进行重传；其中，所述第一预设条件包括如下至少一项：
所述第一上行数据对应的第一定时器超时，所述第一定时器用于在超时的情况下允许对所述第一上行数据进行重传；
所述第一上行数据对应的第二定时器处于运行状态，所述第二定时器用于在运行期限内禁止上行数据新传。
例如，在所述第一上行数据对应的第一定时器超时的情况下，则终端对发送失败的第一上行数据进行重传。需要说明的是，所述第一定时器用于在超时的情况下允许对所述第一上行数据进行重传，在一些实施方式中，所述第一定时器也可以称之为重传定时器。例如，终端在发送HARQ进程-1的第一上行数据后，启动该第一上行数据对应的重传定时器(如retransmissionTimer)，若该重传定时器超时，则终端可以进行所述第一上行 数据的重传。
或者，在所述第一上行数据对应的第二定时器处于运行状态的情况下，则终端对发送失败的第一上行数据进行重传，所述第二定时器用于在超时的情况下允许对所述第一上行数据进行重传，在一些实施方式中，所述第二定时器也可以称之为新传禁止定时器。例如，终端在发送HARQ进程-1的第一上行数据后，启动该第一上行数据对应的新传禁止定时器(如configureGrantTimer)，若该新传禁止定时器仍然运行，或者说该新传禁止定时器没有停止或重启，则终端进行所述第一上行数据的重传。
进一步地，所述第一定时器和所述第二定时器中的至少一者的启动条件或重启动条件包括如下任意一项：
所述终端进行了第二上行数据的发送；
所述终端进行了所述第一上行数据的重传；
在预设时间内未接收到所述网络侧设备发送的反馈信息。
可以理解地，所述第二上行数据不同于所述第一上行数据，终端进行了第二上行数据的发送也可以表述为终端进行了新数据的发送，这种情况下，终端可以进行所述第一定时器和/或所述第二定时器的启动或重启动。或者，在终端进行了所述第一上行数据的重传的情况下，终端也可以对所述第一定时器和/或所述第二定时器进行启动或重启动。
另外，终端在向网络侧设备发送第一上行数据时，可以是启动第一定时器，若在预设时间内未接收到网络侧设备发送的对于该第一上行数据的接收反馈的反馈信息，则终端可以是对所述第一定时器进行重启动，和/或，对所述第二定时器进行启动。
本申请实施例中，还可以对第一定时器和第二定时器的停止条件进行限定。可选的，在满足第二预设条件的情况下，所述第一定时器停止；其中，所述第二预设条件包括如下任意一项：
接收到所述网络侧设备发送的反馈信息；
所述第二定时器停止；
所述第二定时器超时；
所述第二定时器重启动。
可以理解地，终端是在向网络侧设备发送第一上行数据时，启动第一定时器，以对所述第一上行数据的发送进行定时或者说计时。所述第一定时器停止，也即停止定时或者说计时。例如，终端在发送所述第一上行数据后，若接收到网络侧设备发送的对于该第一上行数据的接收反馈的反馈信息，无论该反馈信息是指示第一上行数据接收失败还是接收成功，终端都可以停止第一定时器。
所述第二定时器用于在运行期限内禁止上行数据新传，若所述第二定时器停止，也就不再禁止上行数据新传，终端也就能够进行新数据的传输，则可以停止用于对第一上行数据定时的第一定时器。或者，若所述第二定时器超时或者重启动，也可以停止第一定时器。
可选的，在满足第三预设条件的情况下，所述第二定时器停止；其中，所述第三预设条件包括：接收到所述网络侧设备发送的反馈信息。也就是说，终端在发送第一上行数据后，若接收到网络侧设备发送的对于该第一上行数据的接收反馈的反馈信息，无论该反馈信息是指示第一上行数据接收失败还是接收成功，终端都可以停止第二定时器。
本申请实施例中，所述网络侧设备发送的所述反馈信息用于指示如下任意一项：
所述第一上行数据接收成功；
所述第一上行数据接收失败；
所述终端进行第二上行数据的发送。
可以理解地，终端在向网络侧设备发送第一上行数据后，所述网络侧设备能够向终端发送针对所述第一上行数据接收反馈的反馈信息。若网络侧设备接收到第一上行数据，所述反馈信息可以是指示所述第一上行数据接收成功；若网络侧设备未接收到所述第一上行数据，所述反馈信息可以是指示所述第一上行数据接收失败，或者还可以是指示终端进行第二上行数据的发送，也就是指示终端发送新数据。或者，网络侧设备在成功接收到所述第一上行数据的情况下，所述反馈信息也可以指示终端进行第二上行数据的发送。
本申请实施例中，对所述第一上行数据进行重传的资源包括如下任意一项：
所述专属上行资源；
所述随机接入过程中的上行资源。
也就是说，终端通过专属上行资源向网络侧设备发送第一上行数据，在第一上行数据发送失败的情况下，终端可以仍然通过专属上行资源对所述第一上行数据进行重传。
或者，终端通过专属上行资源向网络侧设备发送第一上行数据，在第一上行数据发送失败的情况下，终端可以是通过随机接入过程中的上行资源对所述第一上行数据进行重传。
或者，终端通过随机接入过程中的上行资源向网络侧设备发送第一上行数据失败后，仍然通过随机接入过程中的上行资源对所述第一上行数据进行重传。或者，终端通过随机接入过程中的上行资源向网络侧设备发送第一上行数据失败后，终端可以是通过专属上行资源对所述第一上行数据进行重传。
本申请实施例中，对第一上行数据进行重传的重传资源可以是具有相同的资源类型，或者也可以是不同的资源类型，例如随机接入信道(Random Access Channel，RACH)上行资源或上行链路资源(Preconfigured Uplink Resource，PUR)等。
可选的，所述对所述第一上行数据进行重传，包括如下任意一项：
在所述第一上行数据存储于缓存内的情况下，从所述缓存内提取所述第一上行数据，并将所述第一上行数据通过重传资源对应的混合自动重传请求HARQ进程进行重传；
获取发送所述第一上行数据的第一HARQ进程，在所述重传资源对应的HARQ进程为所述第一HARQ进程的情况下，将所述第一上行数据通过所述重传资源对应的第一HARQ进程进行重传；
获取发送所述第一上行数据的第一HARQ进程，在所述重传资源对应的HARQ进程为第二HARQ进程的情况下，将所述第一上行数据通过所述重传资源对应的所述第二HARQ进程进行重传。
在第一种实施方式中，终端可以是将所述第一上行数据放入特定的缓存内进行存储，当进行第一上行数据重传时，终端从该特定的缓存内取出所述第一上行数据，并放入重传资源对应的HARQ进程后进行重传。例如，终端 在使用专属上行资源(如uplink grant-1)发送第一上行数据时，终端将所述第一上行数据(如MAC PDU-1)放入特定的预设资源(如Msg3/MsgA/PUR缓存)内存储，当终端使用重传资源(如uplink grant-2)对所述第一上行数据进行重传时，终端从该特定的缓存内取出第一上行数据，并通过重传资源对应的HARQ进程发送该第一上行数据。
在第二种实施方式中，终端在使用专属上行资源(如uplink grant-1)发送第一上行数据时，终端将第一上行数据(如MAC PDU-1)通过HARQ进程-1进行传输；当终端使用重传资源(如uplink grant-2)对所述第一上行数据进行重传时，如果该重传资源对应的HARQ进程也是HARQ进程-1，则终端通过该重传资源对应的HARQ进程-1对第一上行数据进行重传。
在第三种实施方式中，终端在使用专属上行资源(如uplink grant-1)发送第一上行数据时，终端将第一上行数据(如MAC PDU-1)通过HARQ进程-1进行传输；当终端的重传资源(如uplink grant-2)对应的HARQ进程是HARQ进程-2时，则终端可以是通过该重传资源对于HARQ进程-1的数据(也即第一上行数据)通过HARQ进程-2进行重传。
需要说明的是，所述重传资源能够发送的数据大小可以是与所述第一上行数据的数据大小相同，例如，终端发送的第一上行数据MAC PDU-1的数据大小为10字节，则可以限定重传资源的能够发送的数据大小也必须是10字节。
或者，所述重传资源能够发送的数据大小也可以与所述第一上行数据的数据大小不同。在所述重传资源能够发送的数据大小与所述第一上行数据的数据大小不同的情况下，对所述第一上行数据进行重构后通过重传通道进行重传；其中，重构后的第一上行数据的数据大小与所述重传资源能够发送的数据大小匹配。例如，终端发送的第一上行数据MAC PDU-1的数据大小为10字节，而重传资源能够发送的数据大小为20字节，则终端可以根据MAC PDU-1的数据进行重构，重新生成一个20字节的MAC PDU-2后，将该MAC PDU-2通过重传资源进行发送。
本申请实施例中，所述重传资源的时间位置通过如下任意一项确定：
所述终端确定进行重传的时间位置；
所述终端确定进行重传的时间位置之后的预设个时间位置。
例如，终端确定要进行重传的时间位置后，确定该时间位置最近可用的重传资源，进而也就确定了该重传资源的时间位置。或者，终端确定要进行重传的时间位置后的预设个时间位置，确定该预设个时间位置后最近可用的重传资源，进而以确定重传资源的时间位置。

本申请实施例中，终端可以根据网络侧设备的配置或协议规定的条件停止第一上行数据的发送或重传。
例如在一种实施方式中，终端接收到网络侧设备发送的第二配置信息，该第二配置信息用于指示所述第一上行数据的传输次数或传输时长，终端基于所述第二配置信息，也就能够在满足了传出次数或传输时长的条件后，停止所述第一上行数据的发送或重传。
例如，网络侧设备配置终端自主的选择重传资源对第一上行数据进行重传的次数为3次(则第一上行数据总的传输次数为4次)；或者，网络侧设备配置终端自主的选择重传资源对第一上行数据总的传输次数为4次(则第一上行数据重传的次数为3次)。或者，网络侧设备配置终端自主的选择重传资源进行第一上行数据重传的总的数据传输时长为20ms，终端在进行第一上行数据发送后，启动传输时长定时器，则该传输时长定时器的运行时长为20ms，在该传输时长定时器运行期间内，终端可以自主的旋转重传资源进行第一上行数据的重传。
或者，所述第一上行数据的传输次数或传输时长也可以是协议规定，终端基于协议规定，也就能够在满足了传出次数或传输时长的条件后，停止所 述第一上行数据的发送或重传。
或者，终端也可以基于接收到的预设指示信息停止所述第一上行数据的发送或重传，所述预设指示信息可以是网络侧设备发送。需要说明的是，所述网络侧设备发送的预设指示信息，也可以是网络侧设备发送的用于指示终端进行第二上行数据发送的反馈信息。
本申请实施例提供的技术方案中，终端向网络侧设备发送第一上行数据，在确认第一上行数据发送失败的情况下，可以对所述第一上行数据进行重传。这样，终端在数据传输失败的情况下，并不会放弃该数据的传输，而是能够对传输失败的数据进行重传，避免数据的丢失，增加了网络侧设备对数据接收成功的机率，提高了终端与网络侧设备之间数据传输的可靠性。
