第四方面，本发明实施例还提供了一种网络设备，该网络设备包括发送模块；该发送模块，用于向UE发送下行信号，该下行信号中包括第一TA和第一指示信息，该第一指示信息用于指示该UE将通过第二目标信道发送第二上行信号的TA作为第二TA，该第一TA和该第二TA用于该UE确定目标TA，该目标TA用于该UE通过第一目标信道发送第一上行信号，该第二目标信道为多个信道中的一个信道，该多个信道为该UE向该网络设备发送该第二上行信号的信道。

下面结合图2中对本发明实施例的信号传输方法进行说明。图2为本发明实施例提供的一种信号传输方法的流程示意图，如图2所示，该信号传输方法包括步骤201和步骤202：
步骤201、UE确定目标TA。
步骤202、UE采用目标TA，通过第一目标信道发送第一上行信号。
其中，目标TA为第一TA与第二TA的加权值或第一TA，该第一TA为网络设备发送的TA；该第二TA为UE通过第二目标信道发送第二上行信号的TA，第二目标信道为多个信道中的一个信道，该多个信道为UE向网络设备发送第二上行信号的信道。
需要说明的是，在目标TA为第一TA与第二TA的加权值的情况下，第一TA为一个TA调整量，在目标TA为第一TA的情况下，第一TA为一个TA值，在UE直接将第一TA作为目标TA，即UE直接使用第一TA的值，通过第一目标信道发送第一上行信号。
需要说明的是，UE采用目标TA，在第一目标信道上发送第一上行信号表示，UE在配置的上行时隙提前目标TA时间开始发送第一上行信号。
可选的，第一上行信号可以为PRACH信号、PUCCH信号、物理上行控制信道(physical uplink control channel，PUSCH)信号以及探测参考信号(sounding reference signal，SRS)等中的任意一个。
可以理解，“PRACH信号”指的是通过PRACH发送的信号、“PUSCH信号”指的是通过PUSCH发送的信号，“PUCCH信号”指的是通过PUCCH发送的信号。其中，PUSCH可作为传输数据信号信道，PRACH可作为传输控制信号信道。
需要说明的是，第一目标信道可以为第二目标信道，也可以包括其他信道，本发明实施例对此不作具体限定。
本发明实施例提供的UE，UE首先确定目标TA，然后UE根据目标TA在第一目标信 道上发送第一上行信号；其中，目标TA为第一TA与第二TA的加权值或第一TA，第一TA为网络设备发送的TA；第二TA为UE通过第二目标信道发送第二上行信号的TA，第二目标信道为多个信道中的一个信道，该多个信道为UE向网络设备发送第二上行信号的信道。通过该方案，由于目标TA是UE根据网络设备发送的第一TA和第二TA的加权值确定的，或者UE直接将网络设备发送的第一TA确定为目标TA，因此，UE可以采用根据第一TA确定的目标TA，发送第一上行信号，如此，由于本发明实施例提供了一种如何使用网络设备发送的TA的方法，因此可以解决现有技术在通过多个信道发送请求消息的场景中，UE无法确定如何使用确认消息中的TA的问题。
一种可能的实现方式中，本发明实施例中提供的信号传输方法，在步骤201之前，还包括步骤203：
步骤203、UE接收网络设备发送的下行信号，该下行信号中包括第一TA。
进而步骤201可以通过步骤201a执行：
步骤201a、UE根据第一TA，确定目标TA。
可选的，UE可以根据第一TA与第二TA的加权值，确定目标TA；UE也可以将第一TA作为目标TA；本发明实施例对此不作具体限定。
可选的，UE可以根据下述规则确定目标TA：
规则一：UE根据在目标信道发送第二上行信号的TA以及第一TA的加权值确定目标TA。其中，目标信道为发送第二上行信号的多个信道中的一个。
规则二：若网络设备针对第二上行信号发送的下行信号中，仅包含了指示目标信道的指示信息，则UE根据通过目标信道上发送的第二上行信号的TA以及第一TA的加权值确定目标TA。
规则三：若网络设备针对第二上行信号发送的下行信号中，既包含了指示多个目标信道的指示信息，则UE根据一个目标信道上发送第二上行信号的第二TA以及第一TA的加权值确定目标TA，该一个目标信道为发送的第二上行信号的多个目标信道中的一个信道。
规则四：若网络设备针对第二上行信号发送的下行信号中，包含了指示目标信道的第一标识，该第一标识用于指示UE在确定目标TA时使用的是哪个信道上发送的第二上行信号的TA，则UE根据第一标识指示的目标信道上发送第二上行信号的TA以及第一TA的加权值确定目标TA。
规则五：UE使用网络设备针对第二上行信号发送的下行信号的第二TA为目标TA。
在本发明实施例中，由于本提供了UE根据网络设备发送的下行信号中包括的第一TA，采用上述规则一至规则五确定目标TA，该目标TA为第一TA与第二TA的加权值或该第一TA，UE可以根据该目标TA发送第一上行信号，因此，基于该方案，可以解决现有技术在通过多个信道发送请求消息的场景中，UE可以确定如何使用确认消息中的TA。一种可能的实现方式中，本发明实施例中提供的信号传输方法，在步骤203之前，还包括步骤204：
步骤204、UE通过多个信道分别向网络设备发送第二上行信号。
基于该方案，UE可以在多个信道分别向网络设备发送第二上行信号，能够提高UE发送的第二上行信号被网络设备接收到的概率。
可选的，第二目标信道为以下任一项：上述多个信道(即，上述UE向网络设备发送 第二上行信号的多个信道)中的一个信道、网络设备在下行信号中指示的上述多个信道中一个信道、网络设备在下行信号指示的至少两个信道中的一个信道，该至少两个信号为上述多个信道中的信道。
需要说明的是，当第二目标信道为上述多个信道中的一个信道时，该第二目标信道可以为UE在上述多个信道中确定的一个信道。当第二目标信道为网络设备在下行信号指示的至少两个信道中的一个信道时，该第二目标信道可以为网络设备在下行信号指示的至少两个信道中由UE确定的一个信道。
需要说明的是，第二目标信道可以为UE发送第二上行信号的多个信道中的一个。
例如，UE通过PRACH和PUSCH发送随机接入请求消息，若UE选择PRACH作为第二目标信道，则第二TA可以为PRACH上发送的随机接入请求消息的TA，若选择PUSCH作为第二目标信道，则第二TA可以为PUSCH上发送的随机接入请求消息的TA。
需要说明的是，UE可以根据下行信号中携带的指示信息确定该下行信号指示的信道为第二目标信道。
示例性的，假设UE在随机接入过程中，向网络设备发送的接入请求消息中携带了随机序列指示(preamble标识)，若UE从网络设备接收的确认请求消息中，可以获取到UE发送的请求接入携带的preamble标识，则UE可以确定下行信号中指示的信道为PRACH。UE从接收的确认请求消息中，可以获取到竞争解决信息，并且可以获取该UE竞争解决成功的标识，则UE可以确定确认请求消息中指示的信道为PUSCH。UE在发送的接入请求消息中携带了UE标识，例如小区无线临时标识(cell radio network temporary identity，C-RNTI)，若UE从接收的确认请求消息中，可以获取到该UE标识，则UE可以确定下行信号中指示的信道为PUSCH。
若UE从网络设备接收的下行消息中，确定第一标识位置1，则UE可以确定该下行消息指示的信道为PUSCH。若UE从网络设备接收的下行消息中，确定第一标识位置0，则UE可以确定下行信号中第一标识指示的信道为PRACH。
需要说明的是，UE可以根据下行信号中携带的标识确定该下行信号指示的多个信道中的一个信道为第二目标信道。
示例性的，假设随机接入过程中，UE向网络设备发送的接入请求消息中携带了preamble标识和C-RNTI，则UE可以将preamble标识指示的PRACH或C-RNTI指示的PUSCH为第二目标信道。
本发明实施例提供的信号传输方法，UE可以将向上述多个信道中的一个信道、网络设备在下行信号中指示的一个信道、网络设备在下行信号指示的上述多个信道指示的至少两个信道中的一个信道确定第二目标信道，UE可以采用上述任一个第二目标信道发送第二上行信号的TA和第一TA确定目标TA，如此，由于本发明实施例提供了的如何使用网络设备发送的TA的方法，因此，可以解决现有技术在通过多个信道发送请求消息的场景中，UE无法确定如何使用确认消息中的TA的问题。
一种可能的实现方式中，本发明实施例提供的信号传输方法，步骤202具体可以通过步骤202a执行：
步骤202a、UE采用目标TA，在目标TA对应的小区或小区组中，通过第一目标信道发送第一上行信号。
需要说明的是，目标TA对应的小区组中可以包括一个小区，也可以包括多个小区，每个小区中包括第一目标信道。
示例性的，小区组1(小区1、小区2)对应第三TA，算出目标TA之后，将第三TA更新为目标TA。UE采用目标TA，通过第一目标信道发送第一上行信号。
可以理解，当UE确定出一个目标TA后，UE可以在小区组中可以使用该TA，通过第一目标信道发送第一上行信号。
可选的，第二上行信号为接入请求消息，上述的下行信号为接入确认消息或者接入响应消息。则UE可以按照下述的规则A-规则E使用目标TA发送第一上行信号。
可选的，UE请求接入网络设备的接入请求消息，具体可以为随机接入过程中的随机接入请求消息；网络设备确认UE接入网络设备的接入确认消息，具体可以为随机接入过程中的随机接入确认消息。
规则A：在UE在本次接入网络设备的过程中处于空闲态(IDLE)或者去激活态(INACTIVE)的情况下，第一上行信号为对UE对接入确认消息的反馈消息。
示例性的，假设UE通过多个信道发送MsgA第一次尝试接入网络设备，UE在收到MsgB后，如果UE需要对接入确认消息发送反馈消息，则UE使用该目标TA仅用于发送该次随机接入过程中接收的MsgB的反馈消息。其中，“对接入确认消息的反馈消息”可以为UE成功接收MsgB的指示消息(ACK)，也可以为UE接收失败MsgB的指示消息(NACK)。当UE在第一次尝试接入网络设备之后，若UE再次通过多个信道发送MsgA尝试随机接入网络设备，则UE不使用该目标TA发送第一上行信号(例如，停止TAT定时器)。
可以理解，UE和网络设备可以协议约定在UE在本次接入网络设备的过程中处于空闲态或者去激活态的情况下，可以使用目标TA向网络设备发送UE对本次接收的接入请求消息的反馈消息。
规则B：在UE在本次接入网络设备的过程中处于空闲态或者去激活态的情况下，第一上行信号为UE在下次接入网络设备的过程中发送的接入请求消息。
通常，若UE在本次接入网络设备的过程中处于空闲态或者去激活态，则本次接入过程为竞争的接入过程。
示例性的，假设UE通过多个信道发送MsgA第一次尝试随机接入网络设备，UE在收到MsgB后，若UE在本次随机接入网络设备的过程中处于IDLE状态或者INACTIVE状态，且第一次随机接入过程没有完成；当UE第二次尝试随机接入网络设备时，UE可以使用目标TA再次发送MsgA。
可选的，UE可以使用目标TA通过多个信道中的任意一个信道再次发送MsgA，例如PRACH、PUSCH发送MsgA，也可以使用目标TA通过PRACH以及PUSCH再次发送MsgA。
基于该方案，UE在本次接入网络设备的过程中处于空闲态或者去激活态的情况下，能够使用目标TA在下次接入网络设备的过程中发送的接入请求消息。
规则C：在UE在本次接入网络设备的过程中处于连接态，且UE采用竞争方式接入网络设备的情况下，第一上行信号为UE对接入确认消息的反馈消息。
示例性的，若一个随机接入过程为竞争的随机接入过程，假设UE通过多个信道发送 MsgA第一次尝试随机接入网络设备，UE在收到MsgB后，如果UE需要对接入确认消息发送反馈消息，则UE使用该目标TA仅用于发送该次随机接入尝试的MsgB的反馈消息。当UE在第一次尝试随机接入网络设备之后，若UE再次尝试随机接入网络设备，则UE不使用该目标TA(例如，停止TAT定时器)。
基于该方案，在本次接入网络设备的过程中处于连接态，且UE采用竞争方式接入网络设备的情况下，UE能够使用目标TA向网络设备发送UE对本次接收的接入确认消息的反馈消息。
规则D：在UE在本次接入网络设备的过程中处于连接态，且UE采用竞争方式接入网络设备的情况下，第一上行信号为UE在下次接入网络设备的过程中发送的接入请求消息。
示例性的，若一个随机接入过程为竞争的随机接入过程，假设UE通过多个信道发送MsgA第一次尝试随机接入网络设备，UE在本次接入网络设备的过程中处于连接态，UE在收到MsgB后，若第一次尝试随机接入网络设备没有完成，则当UE再次尝试随机接入网络设备，可以使用目标TA向网络设备发送MsgA。
可选的，UE可以在下次接入网络设备的过程中使用目标TA通过多个信道中的任意一个或多个信道发送MsgA。
基于该方案，在UE在本次接入网络设备的过程中处于连接态，且UE采用竞争方式接入网络设备的情况下，UE能够使用目标TA在下次接入网络设备的过程中发送接入请求消息。
规则E：在UE接入网络设备的过程成功完成的情况下，则第一上行信号为UE处于连接态的情况下向网络设备发送的所有上行信号，第一上行信号为接收确认消息中指示的信道类型对应的上行信号。
示例性的，本次随机接入过程为非竞争的随机接入过程，UE在本次随机接入网络设备的过程中处于CONNECTED状态(即连接态)，在本次随机接入过程成功完成后，UE可以采用确定的目标TA发送MsgB中指示的信道类型对应的上行信号，例如根据目标TA发送PUSCH、PUCCH、SRS的上行信号。
示例性的，本次随机接入过程为竞争的随机接入过程，UE在本次随机接入网络设备的过程中处于CONNECTED状态，在本次随机接入过程成功完成后，UE可以采用确定的目标TA发送MsgB中指示的信道类型对应的上行信号，例如MsgB中指示的信道类型包括PUSCH、PUCCH和SRS的上行信号的信道，则UE可以根据目标TA发送PUSCH、PUCCH、SRS的上行信号。
需要说明的是，MsgB中携带MsgA中的preamble ID或者UE ID则可以表示UE接入网络设备的过程成功完成。
可选的，UE在发送PUSCH的上行信号时，可以采用初始TA，也可以采用目标TA，本发明实施例对此不作具体限定。
可以理解，若本次接入网络设备的过程成功完成，则UE可以使用目标TA在UE接入完成后处于连接态的情况下向网络设备发送的所有上行信号。
下面针对UE不使用UE确定的目标TA的规则F和规则G进行说明：
规则F：在UE在本次接入网络设备的过程完成后处于空闲态或者去激活态的情况下， 则UE确定的目标TA不再用于该次接入过程之后的上行信号的发送。
规则G：在UE在本次接入网络设备的过程没有成功完成的情况下，则UE后续发送的上行信号不再使用该次随机接入过程中UE确定的目标TA。
例如，若该次随机接入过程为非竞争的随机接入过程，UE在本次随机接入网络设备的过程中处于CONNECTED状态(即连接态)，且该次随机接入过程没有成功完成，则UE后续发送的上行信号均不使用该次随机接入过程中UE确定的目标TA。若该次随机接入过程为竞争的随机接入过程，UE在本次随机接入网络设备的过程中处于CONNECTED状态(即连接态)，且该次随机接入过程没有成功完成，则UE后续发送的上行信号均不使用该次随机接入过程中UE确定的目标TA。
可以理解，UE可在上述情况下不再使用目标TA发送第一上行信号。
通常，网络设备可以对UE使用的目标TA值设置一个定时器(time alignment timer，TAT)，在定时器超时前，若UE获取了一个新的TA值后，UE可以启动或者重新启动TAT，当按照本发明实施例中，若UE不在使用目标TA发送第一上行信号时，UE可以控制该定时器停止工作。
下面以UE和网络设备的交互方式对本发明实施例提供的信号传输方法进行具体描述。为了便于说明，以UE请求随机接入网络设备为例，以UE通过第一信道和第二信道发送接入请求消息为例。
一种可能的实现方式中，本发明实施例中的信号传输方法，可以包括步骤T：
步骤T：网络设备向用户设备UE发送下行信号。
其中，下行信号中包括第一TA和第一指示信息，第一指示信息用于指示UE将通过第二目标信道发送第二上行信号的TA作为第二TA，第一TA与第二TA用于UE确定目标TA，目标TA用于UE通过第一目标信道发送第一上行信号，第二目标信道为多个信道中的一个信道，多个信道为UE向网络设备发送第二上行信号的信道。
基于该方案，网络设备可以向UE发送下行信号，UE通过接收该下行信号可以确定第一定时提前量TA和第一指示信息，UE根据第一定时提前量TA和第一指示信息指示的TA确定目标TA。
图3为本发明实施例提供的一种信号传输方法的流程示意图，如图3所示，该信号传输方法包括步骤301至步骤306：
步骤301、UE在第一信道和第二信道上分别向网络设备发送接入请求消息。
需要说明的是，本发明实施例中，UE可以在两个及两个以上信道上分别向网络设备发送接入请求消息，第一信道和第二信道均可以为PUSCH、PRACH、PUCCH以及发送SRS的信道等其他信道，本发明实施例对此不作具体限定。
通常，UE在向网络设备发送接入请求消息时，可以使用不同的信道发送，本发明实施例中，可以使用两个以上的信道发送接入请求消息，每个信道默认对应一个初始的TA值，例如PRACH、PUSCH、PUCCH以及SRS对应的初始TA值可以为0，也可以根据下行路径损耗等参数，估算一个TA值。
具体的，UE根据第一信道的初始TA，在第一信道上发送接入请求消息；并且，UE根据第二信道的初始TA，在第二信道上发送接入请求消息。
通常，不同信道的初始TA可以不同，即UE使用的是哪一个信道发送接入请求消息， 在发送后续的上行信号(即，第一上行信号)时可以延长该信道对应的TA发送上行信号。
需要说明的是，本发明实施例中，同一个UE在不同的信道上发送信息的发送时隙不同。
步骤302、网络设备接收接入请求消息。
通常，网络设备在接收接入请求消息后，根据接入请求消息以及资源的使用情况确认UE是否接入网络设备。
需要说明的是，网络设备可以在第一信道上从UE接收接入请求消息，网络设备也可以在第二信道上从UE接收接入请求消息，网络设备也可以既在第一信道上，也可以在第二信道上从UE接收接入请求消息，本发明实施例对此不作具体限定。
相应的，网络设备可以根据接收的接入请求消息以及实时的资源占用情况，确定向UE发送的接入确认消息中携带的信息。
步骤303、网络设备向UE发送接入确定消息。
其中，接入确定消息用于指示UE接入网络设备，接入确定消息中包括第一TA。
需要说明的是，当网络设备确定UE不能接入网络设备后，网络设备向UE发送的确认消息用于指示该UE没有接入网络设备，该确认消息不包括第一TA。
步骤304、UE从网络设备接收该接入确定消息。
需要说明的是，UE可能从网络设备接收了多个用于确认该UE接入网络设备的消息，该接入确定消息为UE从接收的多个确认该UE接入网络设备的消息中，确定的有效的接入确认消息。
可选的，接入确定消息中可以指示第一上行信号的类型，该第一上行信号的类型为网络设备指示UE可以发送的第一上行信号的类型。例如，接入确认消息中指示发送的第一上行信号可以为PRACH信号、PUCCH信号、物理上行控制信道(physical uplink control channel，PUSCH)信号以及探测参考信号(sounding reference signal，SRS)等中的任意一个。
步骤305、UE根据第一TA，确定目标TA，目标TA为第一TA与第二TA的加权值或该第一TA。
其中，第二TA为与第一目标信道对应的TA，该第一目标信道为UE向网络设备发送接入确认消息的信道，接入确认消息用于请求接入网络设备。
下面，针对“UE将第一TA与第二TA的加权值，确定为目标TA”进行简要说明。可以理解的是，UE可以根据第一TA与第二TA按照一定的比例计算目标TA，当然也可以根据第一TA与第二TA的和确定目标TA。为了便于说明，假设第一信道为PRACH，第二信道为PUSCH，接入请求消息为MsgA，接入确认消息为MsgB，第一TA为TA relative，第二TA为TA MsgA，目标TA为TA new。即，TA new＝K 1TA relative+K 2TA MsgA。
下面以K 1＝1，K 2＝1，也即以UE将第一TA与第二TA的和，结合规则一至规则五对如何确定为目标TA为例进行说明。
规则1(对应规则一)：UE根据目标信道的发送MsgA时的TA值与第一TA的和确定目标TA。目标信道为PRACH或PUSCH。
例如，UE采用通过PRACH发送MsgA的TA值(即，TA msgA＝TA PRACH)和第一TA的和确定目标TA，即TA new＝TA relative+TA PRACH。
或者，UE采用通过PUSCH发送MsgA的TA值(即，TA msgA＝TA PUSCH)和第一TA的和确定目标TA，即TA new＝TA relative+TA PUSCH。
需要说明的是，在第一次随机接入时，UE通过目标信道发送MsgA时的TA值为该目标信道发送上行消息的初始TA值，根据初始值确认了目标TA值之后，若UE又接收了一个第二TA，则若继续使用该目标信道的发送的上行信号的TA值，则为UE根据上一个确定的目标TA和新接收的第二TA确定新的目标TA。
可以理解，UE可以根据发送请求消息中的PRACH或者PRACH发送MsgA的TA值和第一TA的和确定目标TA，能够使得UE根据确定的目标TA发送第一上行信号，因此，可以解决现有技术在通过多个信道发送请求消息的场景中，UE无法确定如何使用确认消息中的TA的问题。
规则2(对应规则二)：若MsgB中仅包括确定目标信道的指示信息，则UE采用目标信道的发送MsgA的TA与第一TA的和确定目标TA。
若MsgB中仅包括UE采用PRACH发送MsgA的指示信息(例如，MsgB中包含UE发送的MsgA中的preamble标识)，则UE采用PRACH的发送MsgA的TA与第一TA的和确定目标TA，即TA new＝TA relative+TA PRACH。可以理解，在规则2下，UE通过包括PRACH的多个信道向网络设备发送请求信息时，若UE接收的确认请求消息中，包含了UE通过PRACH发送接入请求消息的指示，可以将采用PRACH的发送请求消息的TA值作为第二TA。
若MsgB中仅包括UE采用PUSCH发送MsgA的指示信息，则UE采用PUSCH的发送MsgA的TA值与第一TA的和确定目标TA，即TA new＝TA relative+TA PUSCH。例如，MsgB中包含竞争解决信息，且UE竞争解决成功。或者，MsgB中包含UE在MsgA中发送的UE标识。
规则3(对应规则三)：若MsgB中即包括UE采用PUSCH发送MsgA的指示信息，又包括UE采用PRACH发送MsgA的指示信息，则UE根据目标信道的发送MsgA的TA值与第一TA的和确定目标TA。目标信道可以为PRACH信道，也可为PUSCH，本发明实施例对此不作具体限定。
若MsgB中既包括UE采用PRACH发送MsgA的指示信息，又包括UE采用PUSCH发送MsgA的指示信息，则UE采用PRACH发送MsgA的TA值与第一TA的和确定目标TA，即TA new＝TA relative+TA PRACH。
若MsgB中既包括UE通过PRACH发送MsgA的指示信息，又包括UE通过PUSCH发送MsgA的指信息示，则UE采用PUSCH发送MsgA的TA值与第一TA的和确定目标TA，即TA new＝TA relative+TA PUSCH。
规则4(对应规则四)：若MsgB中携带第一标识，该第一标识位用于指示UE在确定目标TA时使用的是哪个信道上发送的接入请求消息的TA。
例如，MsgB中采用1bit的第一标识，若该第一标识置1，则第一标识指示UE计算目标TA时采用PUSCH发送MsgA的TA与第一TA的和确定目标TA，即TA new＝TA relative+TA PUSCH，若该第一标识置0，则第一标识指示UE计算目标TA时采用PRACH发送MsgA的TA与第一TA的和确定目标TA，即TA new＝TA relative+TA PRACH。
需要说明的是，上述示例仅以两个信道为例进行说明，实际应用中可以为两个及两个 以上的信道。第一标识可以采用2bit，可以使用00、01、10和11用于指示采用不同的信道发送MsgA的TA。
下面针对“UE将第一TA，确定为目标TA”进行说明：
规则5(对应规则五)：MsgB中携带的TA relative为目标TA，即TA new＝TA relative。
可以理解，在该规则5下，无论UE发送第二上行信号时使用的TA是哪一个信道的TA，UE在接收到网络设备发送的TA后，将网络设备发送的TA确定为目标TA。
需要说明的是，本发明实施例中，网络设备和UE需要约定同一个计算规则，以使得降低上行信号的干扰。
步骤306、UE采用目标TA，通过第一目标信道发送第一上行信号。
需要说明的是，UE在确定目标TA之后，UE可以根据结合接收的确认接入消息的子帧，在发送上行信号的每个无线帧中与该子帧的编号相同的子帧上，再提前目标TA发送该第一上行信号。
其中，UE发送第一上行信号可以采用发送第二上行信号的信道，也可以在其他信道发送后续的上行信号，本发明实施例对此不作具体限定。
本发明实施例提供的信号传输方法，首先，UE确认目标TA，UE采用该目标TA在第一目标信道上发送第一上行信号。其中，目标TA为第一TA与第二TA的加权值或该第一TA，该第一TA为网络设备发送的TA；该第二TA为第二目标信道的TA，该第二目标信道为多个信道中的一个信道，该多个信道为UE向网络设备发送第二上行信号的信道。通过该方案，由于目标TA是UE根据网络设备发送的第一TA和第二TA的加权值确定的，或者UE直接将网络设备发送的第一TA确定为目标TA，因此，UE可以采用根据第一TA确定的目标TA，发送第一上行信号，如此，由于本发明实施例提供了一种如何使用网络设备发送的TA的方法，因此可以解决现有技术在通过多个信道发送请求消息的场景中，UE无法确定如何使用确认消息中的TA的问题。
图4为本发明实施例提供的一种UE可能的结构示意图，如图4所示，UE 400包括：确定模块401和发送模块402；确定模块401，用于确定目标TA；发送模块402，用于采用确定模块401确定的目标TA，通过第一目标信道发送第一上行信号；其中，目标TA为第一TA与第二TA的加权值或第一TA，第一TA为网络设备发送的TA；第二TA为UE通过第二目标信道发送第二上行信号的TA，第二目标信道为多个信道中的一个信道，该多个信道为UE向网络设备发送第二上行信号的信道。

可选的，第二上行信号为接入请求消息，下行信号为接入确认消息；在UE 400在本次接入网络设备的过程中处于空闲态或去激活态的情况，第一上行信号为UE 400对接入确认消息的反馈消息，或者为UE 400在下次接入网络设备的过程中发送的接入请求消息；或者，在UE 400在本次接入网络设备的过程中处于连接态，且UE 400采用竞争方式接入网络设备的情况下，第一上行信号为UE 400对接入确认消息的反馈消息，或者为UE 400在下次接入网络设备的过程中发送的接入请求消息；或者，在UE 400接入网络设备的过程成功完成的情况下，第一上行信号为UE 400处于连接态的情况下，向网络设备发送的所有上行信号，第一上行信号为接入确认消息中指示的信道类型对应的上行信号。
