当网络侧给UE提供参考时间时，由于空口传输的延时影响，导致UE收到网络侧设备提供的参考时间的时间点与网络侧设备实际发送参考时间的时间点不一致。在UE需要较高精度(例如，1us(即微秒))的参考时间的情况下，UE可以通过发起非竞争的随机接入过程获取上行定时提前量(Timing Advance，TA)，通过该上行定时提前量，UE可以将所接收到的参考时间进行纠正(例如，TA/2为空口传输延时)。
在相关技术中，由于非竞争的随机接入是由网络侧发起的，然而网络侧并不知道UE什么时候需要获取上述参考时间，从而会导致网络侧无法及时的触发非竞争的随机接入，进而导致UE无法及时对所接收到的参考时间进行纠正，导致参考时间的精确度较低。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例，例如除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以 及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B和/或C，表示包含单独A，单独B，单独C，以及A和B都存在，B和C都存在，A和C都存在，以及A、B和C都存在的7种情况。
为了便于描述，以下对本公开实施例涉及的一些术语进行说明：
一、参考时间：
在移动通信系统中，例如，长期演进(Long Term Evolution，LTE)系统，网络侧可以给用户设备(User Equipment，UE)(也可称为终端设备)发送系统消息(例如，系统信息块(System Information Block，SIB)16(也即SIB16)，该系统消息中可以指示参考时间(例如，Treference)。
其中，上述参考时间可以包括如下至少一项：
世界协调时间(Coordinated Universal Time，UTC)；
阳光节约时间(Daylight Saving Time，DST)，也可称为或夏时制时间；
全球定位系统(Global Positioning System，GPS)时间；
本地时间。
当UE接收到参考时间时，为了保证UE侧时间和网络侧时间理解一致，协议约定UE所接收到的参考时间对应的时间位置为：该系统消息的系统消息发送窗口的结束边界所在的系统帧号(System Frame Number，SFN)的边界。
例如，UE接收到参考时间的SIB16的位置为(SFN_2，Subframe_1)，该SIB16的系统消息发送窗口为10个子帧(即Subframe)(其中，1个SFN中有10个子帧)，则UE收到参考时间的SIB16对应系统消息窗口的结束边界为(SFN_3，Subframe_1)，则UE收到的参考时间对应为SFN_3的结束边界时间。
网络侧给UE提供的参考时间来自于特定时钟源。例如，对于网络侧提供给UE的GPS时间，该GPS时间的时钟源可以为GPS卫星；对于网络侧 提供给UE的UTC时间，该UTC时间的时钟源可以为网络侧设备(例如，基站或核心网设备等)连接的可提供UTC时间的原子钟。不同的时钟源可以提供相同或不同类型的参考时间，例如，时钟源1和时钟源2都可以提供UTC时间。当不同的时钟源在提供相同或不同类型的参考时间的时候，其所提供的时间信息的精度可以相同，也可以不同。例如，时钟源1提供的UTC时间的粒度(或时间精度)为1秒，而时钟源2提供的UTC时间的粒度(或时间精度)为1微秒。
二、上行定时：
UE在接收到下行信号后，可以确定下行信号子帧的位置。为了避免上行干扰，网络侧要保证不同UE发送的信号在固定的时刻到达，因此网络侧需要给UE的上行发送配置一个上行定时提前量，即TA。UE在收到该TA值后，若UE要发送上行信号，则UE可以以下行子帧位置为参考再提前TA值进行上行信号的发送。
对于TA值的获取：由于UE只有在上行失步状态才需要获取TA值，因此可以UE自己触发或网络侧触发UE发起随机接入过程，网路侧在随机接入响应中给UE下发TA值。
对于TA值的维护：由于UE的位置在不停的变化，因此需要对TA值的有效性进行维护。网络侧的TA值维护，可以对UE的TA值设置一个时间校准定时器(Time Alignment Timer，TAT)，在下发TA给UE的时候启动，在TAT超时前网络侧下发新的TA值给UE。UE的TA值维护，可以根据网络侧设置的TAT，在收到TA值的时候启动或重启动，在TAT超期后认为该TA值失效，UE上行为失步状态，不能再在上行失步的小区发送上行信号。
本公开实施例提供一种信息传输方法。参见图1，图1是本公开实施例可应用的一种网络系统的结构图，如图1所示，包括终端设备11和网络侧设备12，其中，终端设备11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等用户侧设备，需要说明的是，在本公开实施例中并不限定终端设备11的具体类型。网络侧设备12可以是基站，例如：宏站、LTE演进型基 站(evolved node base station，eNB)、第5代新空口基站(5 th generation New Radio NodeB，5G NR NB)、下一代基站(next generation node base station，gNB)等；网络侧设备12也可以是小站，如低功率节点(Low Power Node，LPN)、微微(pico)、毫微微(femto)等小站，或者网络侧设备12可以是接入点(Access Point，AP)；基站也可以是中央单元(Central Unit，CU)与其管理和控制的多个TRP共同组成的网络节点。需要说明的是，在本公开实施例中并不限定网络侧设备12的具体类型。

终端设备11可以向网络设备12上报参考时间兴趣信息，其中，上述参考时间兴趣信息也即终端设备对参考时间的兴趣信息，可以用于指示终端设备11感兴趣的参考时间和不感兴趣的参考时间等中的至少一项。

实际应用中，网络侧设备可以通过系统信息(例如，SIB10)和/或专属消息(例如，RRCConnectionReconfiguration消息)将参考时间信息下发给终端设备。终端设备可以向网络侧设备上述参考时间兴趣信息，使得网络侧设备基于该参考时间兴趣信息可以获知终端设备是否对相关参考时间(例如，网络侧下发的参考时间)感兴趣，从而能够及时的触发随机接入过程，以及时的对相关的参考时间进行纠正。
本公开实施例中，通过向网络侧设备上报参考时间兴趣信息；其中，所述参考时间兴趣信息用于指示所述终端设备感兴趣的参考时间和不感兴趣的参考时间中的至少一项，使得网络侧可以及时获知终端设备对参考时间的兴趣信息，从而能够及时的触发相关参考时间的纠正过程，提高参考时间的精确性。

本实施例通过协议预定义是否允许终端设备上报参考时间兴趣信息，可以节省信令，实现较为简单。
在另一实施方式中，可以通过网络侧设备指示是否允许终端设备上报参考时间兴趣信息。例如，网路侧设备可以通过系统信息(例如，SIBx)或专属信令(例如，RRCReconfiguration消息)指示是否允许终端设备上报参考时间兴趣信息。在网络侧设备指示允许接收终端设备上报的参考时间兴趣信息时，终端设备才可以上报参考时间兴趣信息。
