具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图1，其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括：网络设备10和终端设备20。
网络设备10是用于为终端设备20提供无线通信服务的设备。网络设备10与终端设备20之间可以通过空口建立连接，从而通过该连接进行通信，包括信令和数据的交互。网络设备10的数量可以有多个，两个邻近的网络设备10之间也可以通过有线或者无线的方式进行通信。终端设备20可以在不同的网络设备10之间进行切换，也即与不同的网络设备10建立连接。
在一个示例中，如图2所示，以NTN为例，NTN中的网络设备10可以是卫星11。一颗卫星11可以覆盖一定范围的地面区域，为该地面区域上的终端设备20提供无线通信服务。另外，卫星11可以围绕地球做轨道运动，通过布设多个卫星11，可以实现对地球表面的不同区域的通信覆盖。
相比于地面的蜂窝通信网络，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以 较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为LEO(Low-Earth Orbit，低地球轨道)卫星、MEO(Medium-Earth Orbit，中地球轨道)卫星、GEO(Geostationary Earth Orbit，地球同步轨道)卫星、HEO(High Elliptical Orbit，高椭圆轨道)卫星等等。目前阶段主要研究的是LEO和GEO。LEO的高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端的发射功率要求不高。GEO的轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
为了保证卫星的覆盖以及提升整个卫星通信***的***容量，卫星采用多波束覆盖地面，一颗卫星可以形成几十甚至数百个波束来覆盖地面；一个卫星波束可以覆盖直径几十至上百公里的地面区域。
在另一个示例中，如图3所示，以蜂窝通信网络为例，蜂窝通信网络中的网络设备10可以是基站12(或称为接入网设备)。基站12是一种部署在接入网中用以为终端设备20提供无线通信功能的装置。基站12可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的***中，具备网络设备功能的设备的名称可能会有所不同，例如在5G NR(New Radio，新空口)***中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本申请实施例中，上述为终端设备20提供无线通信功能的装置统称为网络设备。
另外，本申请实施例中涉及的终端设备20，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端设备。
另外，在本申请实施例中，名词“网络”和“***”通常混用，但本领域技术人员可以理解其含义。
在介绍本申请技术方案之前，先对本申请涉及的一些背景技术知识进行介绍说明。以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
一、NR***中4步随机接入过程和2步随机接入过程
随机接入过程主要有如下事件触发：
1.终端设备初始接入时建立无线连接：终端设备从RRC(Radio Resource Control，无线资源控制)空闲态(RRC_IDLE态)到RRC连接态(RRC_CONNECTED态)；
2.RRC连接重建过程：以便终端设备在无线链路失败后重建无线连接；
3.切换：终端设备需要与新的小区建立上行同步；
4.RRC连接态下，DL(Down Link，下行)数据到达，此时UL(Up Link，上行)处于失步状态；
5.RRC连接态下，UL数据到达，此时UL处于失步状态或者没有用于发送SR(Scheduling Request，调度请求)的PUCCH(Physical Uplink Control Channel，物理上行控制信道)资源；
6.SR失败；
7.来自RRC的同步重配置请求；
8.终端设备从RRC非激活态(RRC_INACTIVE态)转换为RRC连接态(RRC_CONNECTED态)；
9.在SCell(Secondary Cell，辅小区)添加过程中建立时间校准；
10.请求其他SI(System Information，***信息)；
11.波束失败恢复。
在NR Rel-15版本中，主要支持以下两种随机接入方式，基于竞争的随机接入方式(即4步随机接入)和基于非竞争的随机接入方式(即2步随机接入)。
如图4中(a)部分所示，其示出了基于竞争的随机接入(即4步随机接入)过程的示意图。基于竞争的随机接入过程分为4步，详细的步骤如下：
步骤1.终端设备向网络设备发送Msg1(Message1，消息1)。
终端设备选择PRACH(Physical Random Access Channel，物理随机接入信道)资源，并在选择的PRACH上发送选择的preamble(前导码)。如果是基于非竞争的随机接入，PRACH资源和preamble可以由网络设备指定。网络设备基于preamble可以估计上行Timing(定时)，和终端传输Msg3(Message 3，消息3)所需要的grant(调度)大小。
步骤2.网络设备向终端设备发送Msg2(Message2，消息2)，也即网络设备发送RAR(Random Access Response，随机接入响应)给终端设备。
终端设备发送Msg1之后，开启一个随机接入响应时间窗，在该随机接入响应时间窗内监测RA-RNTI(Random Access-Radio Network Temporary Identifier，随机接入-无线网络临时标识)加扰的PDCCH(Physical Downlink Control Channel，物理下行控制信道)。其中，RA-RNTI跟终端设备发送Msg1所使用的PRACH时频资源有关。
终端设备成功接收到RA-RNTI加扰的PDCCH之后，终端设备能够获得该PDCCH调度的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)，其中包含了RAR(Random Access Response，随机接入相应)，RAR具体包含以下信息：
RAR的subheader(包头)中包含BI，用于指示重传Msg1的回退时间；
RAR中的RAPID：网络设备响应收到的preamble index(前导码指示)；
RAR的payload(载荷)中包含了TAG，用于调整上行定时；
UL grant(Uplinkgrant，上行调度)：用于调度Msg3的上行资源指示；
TC-RNTI(Temporary Cell-Radio Network Temporary Identifier，临时小区-无线网络临时标识)：用于加扰Msg4的PDCCH(初始接入)。
如果终端设备接收到RA-RNTI加扰的PDCCH，并且RAR中包含了自己发送的preamble index，则终端设备认为成功接收了随机接入响应。
对于基于非竞争的随机接入，终端设备成功接收Msg2后，随机接入过程结束。对于基于竞争的随机接入，终端设备成功接收Msg2后，还需要继续传输Msg3(Message3，消息3)和接收Msg4(Message 4，消息4)。
步骤3.终端设备在网络调度资源上传输Msg3。
Msg3主要用于通知网络设备该随机接入过程是由什么事件触发。比如，如果是初始接入随机过程，则在Msg3中会携带UE ID(Identity，标识)和establishment cause(建立原因)；如果是RRC重建，则会携带连接态UE标识和establishment cause。
步骤4.网络设备向终端设备发送Msg4。
Msg4有两个作用，一个是用于竞争冲突解决，另一个是网络设备向终端设备传输RRC配置消息。竞争冲突解决有以下两种方式：一种是如果终端设备在Msg3中携带了C-RNTI(Cell-Radio Network Temporary Identifier，小区-无线网络临时标识)，则Msg4用C-RNTI加扰的PDCCH调度。另一种是如果终端设备在Msg3中没有携带C-RNTI，比如是初始接入，则Msg4用TC-RNTI加扰的PDCCH调度，冲突的解决是终端设备接收Msg4的PDSCH，通过匹配PDSCH中的CCCH SDU(Common Control Channel Service Data Unit，通用控制信道服务数据单元)。
NR Rel-16版本引入了2步随机接入过程，其引入可以降低时延同时减小信令开销。
如图4中(b)部分所示，其示出了基于非竞争的随机接入(也即2步随机接入)过程的 示意图。基于非竞争的随机接入过程分为2步，详细的步骤如下：
步骤1.终端设备向网络设备发送MsgA(MessageA，消息A)。
2步随机接入中的MsgA包含在PRACH上传输的preamble和在PUSCH(Physical Uplink Shared Channel，物理上行共享信道)上传输的负载信息。
步骤2.网络设备向终端设备发送竞争冲突解决成功的指示信息，也即MsgB(MessageB，消息B)。
在MsgA传输后，终端设备在配置的窗口内监听网络设备侧的响应，如果收到网络设备下发的MsgB，则终端设备结束随机接入过程，如图4中(b)部分所示；如果在MsgB中收到回退指示，则终端设备执行Msg3的传输并监听竞争冲突解决结果。如果在Msg3传输之后竞争解决不成功，终端继续MsgA的传输。
二、NR***的时序关系
目前NR***中的时序关系如下：
1.PDSCH接收时序：当终端设备被DCI(Downlink Control Information，下行控制信息)调度接收PDSCH时，该DCI中包括K 0的指示信息，该K 0用于确定传输该PDSCH的时隙。例如，如果在时隙n上收到该调度DCI，那么被分配用于PDSCH传输的时隙为时隙
Figure PCTCN2021134275-appb-000001
其中，K 0是根据PDSCH的子载波间隔确定的，μ PDSCH和μ PDCCH分别是用于确定PDSCH和PDCCH配置的子载波间隔的参数。K 0的取值范围是0到32。
2.DCI调度的PUSCH的传输时序：当终端设备被DCI调度发送PUSCH时，该DCI中包括K 2的指示信息，该K 2用于确定传输该PUSCH的时隙。例如，如果在时隙n上收到该调度DCI，那么被分配用于PUSCH传输的时隙为时隙
Figure PCTCN2021134275-appb-000002
其中，K 2是根据PDSCH的子载波间隔确定的，μ PUSCH和μ PDCCH分别是用于确定PUSCH和PDCCH配置的子载波间隔的参数。K 2的取值范围是0到32。
3.RAR grant调度的PUSCH的传输时序：对于被RAR grant调度进行PUSCH传输的时隙，如果终端设备发起PRACH传输后，该终端设备收到包括该对应RAR grant消息的PDSCH的结束位置在时隙n，那么终端设备在时隙n+K 2+Δ上传输该PUSCH，其中，K 2和Δ(delta)是协议约定的。
三、NTN***的时序增强
NR***中的PDSCH接收时序只受下行接收侧的时序影响，不受NTN***中的大传输往返时延的影响，因此NTN***可以重用NR***中的PDSCH接收时序。
对于其他受下行接收和上行发送交互影响的时序，为了能在NTN***中正常工作，或者说，为了克服NTN***中的大传输时延，时序关系需要增强。一个简单的方案是在***中引入一个偏移参数K offset，并将该参数应用到相关的时序关系中。
DCI调度的PUSCH(包括PUSCH上传输的CSI(Channel State Information，信道状态信息))的传输时序：如果在时隙n上收到该调度DCI，那么被分配用于PUSCH传输的时隙为时隙
Figure PCTCN2021134275-appb-000003
RAR grant调度的PUSCH的传输时序：对于被RAR grant调度进行PUSCH传输的时隙，终端设备在时隙n+K 2+Δ+K offset上传输该PUSCH。
PUCCH上传输HARQ-ACK(Hybrid Automatic Repeat request-Acknowledgement，混合自动重传请求-肯定确认)的传输时序：对于PUCCH传输的时隙，如果一个PDSCH接收的结束位置在时隙n或一个指示SPS(Semi-Persistent Scheduling，半静态调度)PDSCH释放的PDCCH接收的结束位置在时隙n，终端设备应在时隙n+K 1的PUCCH资源上传输对应的HARQ-ACK信息，其中K 1是时隙个数并且是通过DCI格式中PDSCH-to-HARQ-timing-indicator信息域来指示的，或是通过dl-DataToUL-ACK参数提供的。K 1＝0对应PUCCH传输的最后一个时隙与PDSCH接收或指示SPS PDSCH释放的PDCCH 接收的时隙重叠。
四、SON(Self-optimizing Network，自优化网络)
SON技术中支持终端上报随机接入报告(RACH report)和CEF(Connection Establishment Failed，连接建立失败)报告，用于网络优化。
具体的，随机接入报告中包括：随机接入所在小区ID(Identifier，标识符)；随机接入的目的；执行随机接入的频点、子载波信息；具体随机接入情况：SSB(Synchronization Signal Block，同步信号块)index、在每一个SSB下随机接入尝试的次数、随机接入尝试是否遇到碰撞(collision)、目标SSB是否高于rsrp-ThresholdSSB阈值。
CEF报告用于体现终端设备执行接入网络时发生的问题或者上下行信号不匹配的问题。上报内容包括：numberOfConnFail、PerRAInfoList、timeSinceFailure等信息。其中，numberOfConnFail用于指示同一个小区里最近连续发生的连接建立或恢复过程的失败次数。PerRAInfoList和随机接入报告中的上报内容一样。timeSinceFailure用于指示连接建立失败发生到现在的时间。
在NTN***中，通过引入偏移参数Koffset来增强上行传输的时序。对于初始接入(initial access)，Msg3调度使用的Koffset是通过***消息配置的。不合适的Koffset参数设置会导致终端设备无法发送Msg3，造成随机接入尝试失败。本申请提出，对于这类失败信息，终端记录下来并上报给网络有助于网络后续优化Koffset参数的配置。下面，将结合几个示例性实施例，对本申请技术方案进行介绍说明。
请参考图5，其示出了本申请一个实施例提供的信息上报方法的流程图，该方法可应用于图1至图3所示的网络架构中，该方法可以包括如下步骤：
步骤510，终端设备向网络设备发送第一信息，该第一信息用于指示因上行资源不可用，导致终端设备无法向网络设备传输第二信息。
相应地，网络设备接收来自终端设备的第一信息。
终端设备需要使用上行资源向网络设备传输第二信息，如果该上行资源不可用，则会导致终端设备无法向网络设备传输第二信息。可选地，上行资源是用于上行传输的时频资源。
可选地，上行资源是由网络设备配置的，或者说是基于网络设备配置的相关信息确定的。可选地，上行资源的时域位置是根据网络设备配置的第一时间偏移确定的。例如，该第一时间偏移可以是上文介绍的Koffset，在本申请实施例中，除特别说明之外，第一时间偏移是指Koffset。第一时间偏移可以由网络设备通过***消息进行配置，例如网络设备广播***消息，该***消息中携带第一时间偏移的指示信息，终端设备基于该指示信息即可确定出第一时间偏移。
可选地，第一信息包括第一时间偏移。由于上行资源的时域位置是根据网络设备配置的第一时间偏移确定的，在上行资源不可用的情况下，那么说明可能是因为该第一时间偏移不合适，因此在终端设备向网络设备上报的第一信息中，包含第一时间偏移，能够使得网络设备当前使用的第一时间偏移是多少，然后对该第一时间偏移或上行资源进行针对性的调整。
可选地，第一信息还包括以下至少一项：网络设备配置的第二时间偏移、终端设备的位置信息、网络设备的位置信息、终端设备的TA(Timing Advance，定时提前)值。可选地，第二时间偏移也是用于确定上行资源的时域位置的，例如终端设备根据第一时间偏移和第二时间偏移，确定用于传输第二信息的上行资源的时域位置。第二时间偏移也可以是网络设备配置的，第二时间偏移可以是上文介绍的K1或K2，在本申请实施例中，除特别说明之外，第二时间偏移是指K1或K2。
在本申请实施例中，对终端设备的位置信息以及网络设备的位置信息的获取方式不作限定。例如，终端设备可以基于一些定位技术获取自身的位置信息，如终端设备基于GNSS(Global Navigation Satellite System，全球导航卫星***)定位获取自身的位置信息。又例如， 在网络设备是卫星的情况下，终端设备可以基于星历信息确定卫星的位置信息。又例如，在网络设备是基站的情况下，终端设备可以动态获取基站的位置信息，例如向基站请求获取其位置信息，或者基于基站发送的信号确定基站的位置信息等，本申请对此不作限定。
可选地，网络设备针对第二时间偏移的配置频率，大于其针对第一时间偏移的配置频率。例如，第二时间偏移是通过DCI动态调度的，其配置相对更加频繁，第一时间偏移是通过***消息或RRC消息配置的，其配置没有第二时间偏移频繁。
可选地，上行资源不可用的原因包括以下至少一项：第一时间偏移的值过小，第一时间偏移与第二时间偏移之和小于终端设备的TA值。例如，因为第一时间偏移的值过小，或者因为第一时间偏移与第二时间偏移之和小于终端设备的TA值，导致终端设备根据第一时间偏移、第二时间偏移和TA值确定出的第二信息的发送时刻，早于调度信息的接收时刻，该调度信息是用于调度第二信息传输的信息，这样就存在问题，说明用于传输第二信息的上行资源已经不可用，终端设备无法向网络设备发送第二信息。
在一个示例中，第二信息包括随机接入过程中的Msg3。在随机接入过程中，网络设备会向终端设备发送RAR，该RAR中包含UL grant(上行调度)信息，其是用于调度Msg3的上行资源指示，终端设备根据该UL grant确定用于传输Msg3的上行资源。如果终端设备在随机接入过程中，因传输Msg3的上行资源不可用导致Msg3发送失败，那么终端设备可以记录并向网络设备上报该信息。
在另一个示例中，第二信息包括通过PUSCH传输的信息。网络设备会向终端设备发送DCI或其他形式的调度信息来调度PUSCH的传输，终端设备根据该DCI或其他形式的调度信息确定出用于传输PUSCH的上行资源。如果因传输PUSCH的上行资源不可用导致PUSCH发送失败，那么终端设备可以记录并向网络设备上报该信息。
在另一个示例中，第二信息包括通过PUCCH传输的信息。网络设备会向终端设备发送DCI或其他形式的调度信息来调度PUCCH的传输，终端设备根据该DCI或其他形式的调度信息确定出用于传输PUCCH的上行资源。如果因传输PUCCH的上行资源不可用导致PUCCH发送失败，那么终端设备可以记录并向网络设备上报该信息。可选地，PUCCH用于传输PDSCH对应的ACK或NACK。当然，在一些其他实施例中，PUCCH还可用于传输一些其他形式的上行信息，本申请对此不作限定。
示例性地，以第一时间偏移为Koffset，第二时间偏移为K2为例，假设Koffset为20ms，当前的TA值为30ms，终端设备收到RAR或PDCCH调度，其中的K2为2ms，由于Koffset+K2＜TA，终端设备确定上行PUSCH资源不可用，并将该信息上报给网络设备。网络设备可以根据该上报的信息，对Koffset进行调整，如将Koffset调整为30ms。相比于对动态调度信息中的第二时间偏移进行调整，本申请通过对第一时间偏移进行调整，有助于节省终端设备和网络设备之间的信令开销。
在一些实施例中，终端设备主动向网络设备发送第一信息；相应地，网络设备接收终端设备主动发送的第一信息。例如，终端设备可以定期或者不定期地主动向网络设备发送第一信息，如终端设备在确定出满足第一信息的上报条件时，主动向网络设备发送第一信息，该上报条件可以是网络设备配置的，也可以是协议规定的，或者终端设备自行确定的，本申请对此不作限定。
在一些实施例中，网络设备向终端设备发送上报请求，终端设备接收来自网络设备的上报请求，终端设备根据上报请求向网络设备发送第一信息，网络设备接收终端设备根据上报请求发送的第一信息。在此示例中，终端设备在接收到网络设备的上报请求之后，再向网络设备上报第一信息，能够避免一些非必要的上报操作，节省传输资源。
本申请实施例提供的技术方案，通过终端设备向网络设备上报第一信息，通过该第一信息向网络设备指示因上行资源不可用，导致终端设备无法向网络设备传输第二信息，使得网络设备能够在接收到该第一信息之后，了解到终端设备无法向其传输第二信息的原因，进而 可以结合实际情况做适当调整，如优化第一时间偏移的配置，这有助于提升终端设备和网络设备之间信息传输的成功率和可靠性。
在一示例性实施例中，以第二信息包括随机接入过程中的Msg3为例，终端设备向网络设备发送第一信息，该第一信息用于指示因传输Msg3的上行资源不可用，导致终端设备无法向网络设备传输Msg3。如图6所示，该实施例的具体实施过程可以包括如下几个步骤(610～630)：
步骤610，终端设备在随机接入过程中，记录每次随机接入尝试失败遇到的原因和相关信息。
示例性地，终端设备记录的信息可以包括：
a)是否因传输Msg3的上行资源不可用，导致Msg3无法传输。导致传输Msg3的上行资源不可用的原因，可能是网络设备配置的第一时间偏移(记为Koffset)过小。具体来讲，Msg2中的RAR会指示用于Msg3传输的UL grant信息，RAR中包含第二时间偏移(记为K2)，终端设备在收到对应RAR grant信息的PDSCH的结束位置延后一个K2值、一个delta值和一个Koffset值后，再应用更新后的TA值确定Msg3的上行PUSCH发送时刻。如果K2+Δ+Koffset<TA，则代表Msg3的发送时刻早于对应RAR grant信息的PDSCH的接收时刻，此时代表传输Msg3的上行资源不可用，即终端设备无法发送Msg3。
b)如果传输Msg3的上行资源不可用，则终端设备额外记录以下一个或多个信息：当前终端设备使用的Koffset、当前调度配置的K2、当前终端设备的位置信息、当前网络设备的位置信息、当前终端设备的TA值。
步骤620，网络设备向终端设备发送上报请求。
可选地，该上报请求是UE信息请求(UEInformationRequest)，网络设备向处于RRC连接态的终端设备发送UE信息请求，该请求指示终端设备上报连接建立失败信息或随机接入过程中的相关信息。
步骤630，终端设备向网络设备发送第一信息，该第一信息用于指示因传输Msg3的上行资源不可用，导致终端设备无法向网络设备传输Msg3。
可选地，该第一信息用于指示因网络设备配置的第一时间偏移(记为Koffset)过小，导致终端设备无法向网络设备传输Msg3。例如，因Koffset过小，导致K2+Δ+Koffset<TA，则代表传输Msg3的上行资源不可用，即终端设备无法发送Msg3。
可选地，第一信息中包括上述每次随机接入尝试失败所记录的相关信息，如以下信息中的至少一个：当前终端设备使用的第一时间偏移(记为Koffset)、当前调度配置的第二时间偏移(记为K2)、当前终端设备的位置信息、当前网络设备的位置信息、当前的TA值。
示例性地，以第一时间偏移为Koffset，第二时间偏移为K2为例，假设Koffset为20ms，当前的TA值为30ms，终端设备收到RAR调度，其中的K2为2ms，并且假设Δ为2ms，由于K2+Δ+Koffset<TA，终端设备确定上行PUSCH资源不可用，并将该信息上报给网络设备。网络设备可以根据该上报的信息，对Koffset进行调整，如将Koffset调整为30ms。这样，终端设备就可以基于调整后的Koffset，向网络设备发送Msg3。
另外，在本实施例中，仅以终端设备在接收到网络设备发送的上报请求之后，再向网络设备发送第一信息为例进行介绍说明。在一些其他实施例中，终端设备也可以主动向网络设备发送第一信息，本申请对此不作限定。
本申请实施例提供的技术方案，针对4步随机接入过程，通过在终端设备和网络设备建立连接之后，终端设备向网络设备上报第一信息，通过该第一信息向网络设备指示因传输Msg3的上行资源不可用，导致终端设备无法向网络设备传输Msg3，使得网络设备能够在接收到该第一信息之后，了解到终端设备无法向其传输Msg3的原因，进而可以结合实际情况做适当调整，如优化第一时间偏移(记为Koffset)的配置，这有助于提升终端设备和网络设 备之间信息传输的成功率和可靠性。
在一示例性实施例中，以第二信息包括通过PUSCH或PUCCH传输的信息为例，终端设备向网络设备发送第一信息，该第一信息用于指示因传输PUSCH或PUCCH的上行资源不可用，导致终端设备无法向网络设备传输PUSCH或PUCCH。如图7所示，该实施例的具体实施过程可以包括如下几个步骤(710～720)：
步骤710，终端设备在处于连接态的情况下，记录PUSCH或PUCCH传输失败的原因和相关信息。
示例性地，终端设备记录的信息可以包括：
a)是否因传输PUSCH的上行资源不可用，导致PUSCH无法传输。导致传输PUSCH的上行资源不可用的原因，可能是网络设备配置的第一时间偏移(记为Koffset)过小。具体来讲，PDCCH会指示用于PUSCH传输的UL grant信息，其中包含第二时间偏移(记为K2)，终端设备在收到PDCCH的时刻延后一个K2值和一个Koffset值后，再应用TA值确定PUSCH的上行发送时刻。如果K2+Koffset<TA，则代表PUSCH的发送时刻早于PDCCH的接收时刻，此时代表传输PUSCH的上行资源不可用，即终端设备无法发送PUSCH。
b)是否因传输PUCCH的上行资源不可用，导致PUCCH无法传输。导致传输PUCCH的上行资源不可用的原因，可能是网络设备配置的第一时间偏移(记为Koffset)过小。具体来讲，PDCCH会指示用于PUCCH传输的UL grant信息，其中包含第二时间偏移(记为K1)，终端设备在收到PDCCH的时刻延后一个K1值和一个Koffset值后，再应用TA值确定PUCCH的上行发送时刻。如果K1+Koffset<TA，则代表PUCCH的发送时刻早于PDCCH的接收时刻，此时代表传输PUCCH的上行资源不可用，即终端设备无法发送PUCCH。
可选地，上述PUCCH用于传输PDSCH对应的ACK或NACK，例如网络设备通过PDCCH指示PDSCH对应的ACK或NACK反馈的上行资源。
c)如果传输PUSCH或PUCCH的上行资源不可用，则终端设备额外记录以下一个或多个信息：当前终端设备使用的Koffset、当前调度配置的K2或K1、当前终端设备的位置信息、当前网络设备的位置信息、当前终端设备的TA值。
步骤720，终端设备向网络设备发送第一信息，该第一信息用于指示因传输PUSCH或PUCCH的上行资源不可用，导致终端设备无法向网络设备传输PUSCH或PUCCH。
可选地，该第一信息用于指示因网络设备配置的第一时间偏移(记为Koffset)过小，导致终端设备无法向网络设备传输PUSCH或PUCCH。例如，因Koffset过小，导致K2+Koffset<TA或K1+Koffset<TA，则代表传输PUSCH或PUCCH的上行资源不可用，即终端设备无法发送PUSCH或PUCCH。
可选地，第一信息中包括上述每次传输失败所记录的相关信息，如以下信息中的至少一个：当前终端设备使用的第一时间偏移(记为Koffset)、当前调度配置的第二时间偏移(记为K2或K1)、当前终端设备的位置信息、当前网络设备的位置信息、当前的TA值。
示例性地，以第一时间偏移为Koffset，第二时间偏移为K2或K1为例，假设Koffset为30ms，当前的TA值为40ms，终端设备收到PDCCH调度，其中的K2或K1为4ms，由于K2或K1+Koffset<TA，终端设备确定上行PUSCH或PUCCH资源不可用，并将该信息上报给网络设备。网络设备可以根据该上报的信息，对Koffset进行调整，如将Koffset调整为40ms。这样，终端设备就可以基于调整后的Koffset，向网络设备发送PUSCH或PUCCH。
可选地，网络设备向终端设备发送上报请求。可选地，该上报请求是UE信息请求(UEInformationRequest)，网络设备向处于RRC连接态的终端设备发送UE信息请求，该请求指示终端设备上报传输失败信息或上下行传输过程中的相关信息。终端设备在接收到网络设备发送的上报请求之后，再向网络设备发送第一信息。在一些其他实施例中，终端设备也可以主动向网络设备发送第一信息，本申请对此不作限定。
本申请实施例提供的技术方案，针对PUSCH或PUCCH(包括但不限于ACK或NACK反馈)的传输，通过终端设备向网络设备上报第一信息，通过该第一信息向网络设备指示因传输PUSCH或PUCCH的上行资源不可用，导致终端设备无法向网络设备传输PUSCH或PUCCH，使得网络设备能够在接收到该第一信息之后，了解到终端设备无法向其传输PUSCH或PUCCH的原因，进而可以结合实际情况做适当调整，如优化第一时间偏移(记为Koffset)的配置，这有助于提升终端设备和网络设备之间信息传输的成功率和可靠性。
