当前，随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性，为此第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)国际标准组织开始研发第五代(5th Genenration，5G)。5G的主要应用场景为：增强移动宽带(enhanced Mobile BroadBand， eMBB)，海量机器类型通信(massive Machine TypeCommunication，mMTC)，高可靠低延迟通信(Ultra-Reliable and Low Latency Communications，URLLC)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标，其需求增长十分迅速。另一方面，由于eMBB可能部署在不同的场景中，便如室内，市区，农村等，其能力和需求的差别也比较大，所以不能一概而论，必须结合具体的部署场景详细分析。URLLC的典型应用包括：工业自动化，电力自动化，远程医疗操作(手术)，交通安全保障等。mMTC的典型特点包括：高连接密度，小数据量，时延不敏感业务，模块的低成本和长使用寿命等。
NR也可以独立部署，5G网络环境中为了降低空口信令和快速恢复无线连接，快速恢复数据业务的目的，定义一个新的无线资源控制(Radio Resource Control，RRC)状态，即RRC非激活(RRC_INACTIVE)状态，这种状态有别于RRC空闲(RRC_IDLE)状态和RRC激活(RRC_ACTIVE)状态。
RRC_IDLE：移动性为基于UE的小区选择重选，寻呼由核心网(Core Network，CN)发起，寻呼区域由CN配置。基站侧不存在UE接入层(Access Stratum，AS)上下文。不存在RRC连接。
RRC_CONNECTED(也称RRC_ACTIVE)：存在RRC连接，基站和UE存在UE AS上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
RRC_INACTIVE：移动性为基于UE的小区选择重选，存在CN-NR之间的连接，UE AS上下文存在某个基站上，寻呼由无线接入网(Radio Access Network，RAN)触发，基于RAN的寻呼区域由RAN管理，网络侧知道UE的位置是基于RAN的寻呼区域级别的。
3GPP正在研究非地面通信网络设备(Non Terrestrial Network，NTN)技术，NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信，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。
NTN技术可以和各种通信系统结合。例如，NTN技术可以和NR系统结合为NR-NTN系统。又例如，NTN技术可以和物联网(Internet of Things，IoT)系统结合为IoT-NTN系统。作为示例，IoT-NTN系统可以包括NB-IoT-NTN系统和eMTC-NTN系统。
NTN网络由以下至少之一的部分组成：
一个或者多个网关，用于连接卫星和地面公共网络；
馈线链路：用于网关和卫星之间通信的链路；
服务链路：用于终端和卫星之间通信的链路；
卫星：从其提供的功能上可以分为透明转发和再生转发这两种。其中，透明转发：只提供无线频率滤波，频率转换和放大的功能；只提供信号的透明转发，不会改变其转发的波形信号。再生转发：除了提供无线频率滤波，频率转换和放大的功能，还可以提供解调/解码，路由/转换，编码/调制的功能。其具有基站的部分或者全部功能。
星间链路：存在于再生转发网络架构下。
图2为本申请实施例提供的基于透传转发卫星的NTN场景的示意图，图3为本申请实施例提供的基于再生转发卫星的NTN场景的示意图。
如图2所示，对于基于透传转发卫星的NTN场景，网关和卫星之间通过馈线链路(Feeder link)进行通信，卫星和终端之间可以通过服务链路(service link)进行通信。如图3所示，对于基于再生转发卫星的NTN场景，卫星和卫星之间通过星间链路(InterStar link)进行通信，网关和卫星之间通过馈线链路(Feeder link)进行通信，卫星和终端之间可以通过服务链路(service link)进行通信。
在图2和图3中，网关用于连接卫星和地面公共网络(例如数据网络)。馈线链路用于网关和卫星之间通信的链路。服务链路用于终端和卫星之间通信的链路。星间链路存在于再生转发网络架构下。
应理解，上述卫星包括但不限于：低地球轨道(Low-Earth Orbit，LEO)卫星、中地球轨道(Medium-Earth Orbit，MEO)卫星、地球同步轨道(Geostationary Earth Orbit，GEO)卫星、高椭 圆轨道(High Elliptical Orbit，HEO)卫星等等。卫星可采用多波束覆盖地面，例如，一颗卫星可以形成几十甚至数百个波束来覆盖地面。换言之，一个卫星波束可以覆盖直径几十至上百公里的地面区域，以保证卫星的覆盖以及提升整个卫星通信系统的系统容量。
作为示例，LEO卫星的高度范围可以为500千米～1500千米，相应轨道周期约可以为1.5小时～2小时，用户间单跳通信的信号传播延迟一般可小于20毫秒，最大卫星可视时间可以为20分钟，LEO卫星的信号传播距离短且链路损耗少，对用户终端的发射功率要求不高。GEO卫星的轨道高度可以35786km，围绕地球旋转周期可以为24小时，用户间单跳通信的信号传播延迟一般可为250毫秒。
为了保证卫星的覆盖以及提升整个卫星通信系统的系统容量，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。
在陆地通信系统中，信号通信的传播时延通常小于1ms。在NTN系统中，由于终端设备和卫星(或者说网络设备)之间的通信距离很远，信号通信的传播时延很大，范围可以从几十毫秒到几百毫秒，具体的传播时延与以下至少之一相关：卫星轨道高度、卫星通信的业务类型。为了处理比较大的传播时延，NTN系统的定时关系相对于NR系统需要增强。
在NTN系统中，和NR系统一样，UE在进行上行传输时需要考虑定时提前(Timing Advance，TA)的影响。由于系统中的传播时延较大，因此TA值的范围也比较大。当UE被调度在时隙n进行上行传输时，该UE考虑往返传播时延，在上行传输时提前传输，从而可以信号到达网络设备时在网络设备上行的时隙n上。
图4为本申请实施例提供的一种定时关系的示意图，如图4所示，网络设备的下行(例如gNB DL)时隙和上行时隙(例如gNB UL)是对齐的，即网络设备的下行时隙n和网络设备的上行时隙n是对齐的。
终端设备的上行(UE UL)传输，经过传播时延1(Delay1)到达网络设备，即网络设备的上行传输相较于终端设备的上行传输延迟时延1。
网络设备的下行传输，经过传播时延2(Delay2)到达终端设备，即终端设备的下行(UE DL)传输相较于网络设备的下行传输延迟时延2。
为了使终端设备的上行传输和网络设备的上行时隙对齐，终端设备需要使用一个较大的TA值。进一步，终端设备在进行上行传输时，也需要引入一个较大的偏移值(例如Koffset)。
图5为本申请实施例提供的另一种定时关系的示意图，如图5所示，网络设备的下行(例如gNB DL)时隙和上行时隙(例如gNB UL)之间有一个偏移值，该偏移值为网络设备下行-上行帧时间偏移(gNB DL-UL frame timing shift)，即网络设备的下行时隙n和网络设备的上行时隙n是不对齐的。
终端设备的上行(UE UL)传输，经过传播时延1(Delay1)到达网络设备，即网络设备的上行传输相较于终端设备的上行传输延迟时延1。
网络设备的下行传输，经过传播时延2(Delay2)到达终端设备，即终端设备的下行(UE DL)传输相较于网络设备的下行传输延迟时延2。
在这种情况下，如果想要使终端设备的上行传输和网络设备的上行时隙对齐，终端设备只需要使用一个较小的TA值。但是，该情况下网络设备可能需要额外的调度复杂度来处理相应的调度时序。
NR系统中的时序关系如下：
物理下行共享信道(Physical Downlink Shared Channel，PDSCH)接收时序：当UE被下行控制信息(Downlink Control Information，DCI)调度接收PDSCH时，该DCI中包括K0的指示信息，该K0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传输的时隙为时隙其中，K0是根据PDSCH的子载波间隔确定的，μPDSCH和μPDCCH分别用于确定为PDSCH和物理下行控制信道(Physical Downlink Control Channel，PDCCH)配置的子载波间隔。K0的取值范围是0到32。
DCI调度的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的传输时序：当UE被DCI调度发送PUSCH时，该DCI中包括K2的指示信息，该K2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传输的时隙为时隙其中，K2是根据PDSCH的子载波间隔确定的，μPUSCH和μPDCCH分别用于确定为PUSCH和PDCCH配置的子载波间隔。K2的取值范围是0到32。
随机接入响应(Random Access Response，RAR)授权(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UE发起物理随机接入信道(Physical Random Access Channel，PRACH)传输后，该UE收到包括该对应RAR grant消息的PDSCH的结束位置在时隙n，那么UE在时隙n+K2+Δ上传输该PUSCH，其中，K2和Δ是协议约定的。
物理上行控制信道(Physical Uplink Control Channel，PUCCH)上传输混合自动重传请求-确认(Hybrid Automatic Repeat Qequest-Acknowledgment，HARQ-ACK)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或一个指示半持续调度(Semi-Persistent Scheduling，SPS)PDSCH释放的PDCCH接收的结束位置在时隙n，UE应在时隙n+K1内的PUCCH资源上传输对应的HARQ-ACK信息，其中K1是时隙个数并且是通过DCI格式中PDSCH到HARQ定时指示(PDSCH-to-HARQ-timing-indicator)信息域来指示的，或是通过下行数据到上行反馈(dl-DataToUL-ACK)参数提供的。K1＝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。
媒体接入控制控制单元(Medium Access Control Control Element，MAC CE)激活时序：当包括MAC CE命令的PDSCH对应的HARQ-ACK信息在时隙n上传输，该MAC CE命令指示的对应行为以及UE假设的下行配置应从时隙后的第一个时隙开始生效，其中，表示子载波间隔配置μ下每个子帧包括的时隙个数。
PUSCH上的信道状态信息(Channel State Information，CSI)传输时序：PUSCH上的CSI传输时序和一般情况下DCI调度PUSCH传输的传输时序相同。
CSI参考资源时序：对于在上行时隙n′上上报CSI的CSI参考资源是根据单个下行时隙n-nCSI_ref确定的，其中，μDL和μUL分别是下行和上行的子载波间隔配置。nCSI_ref的取值取决于CSI上报的类型。
非周期探测参考信号(Sounding Reference Signal，SRS)传输时序：如果UE在时隙n上收到DCI触发传输非周期SRS，该UE在时隙上传输每个被触发的SRS资源集合中的非周期SRS，其中k是通过每个被触发的SRS资源集合中的高层参数时隙偏移(slotOffset)配置的并且是根据被触发的SRS传输对应的子载波间隔确定的，μSRS和μPDCCH分别是被触发的SRS传输和携带触发命令的PDCCH的子载波间隔配置。
NR系统中的PDSCH接收时序只受下行接收侧的时序影响，不受NTN系统中的大传输往返时延的影响，因此NTN系统可以重用NR系统中的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系统中正常工作，或者说，为了克服NTN系统中的大传输时延，时序关系需要增强。一个简单的方案是在系统中引入一个偏移参数Koffset(也称koffset、Koffset、k_offset或K_offset等)，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)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
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，UE在时隙n+K2+Δ+Koffset上传输该PUSCH。
PUCCH上传输HARQ-ACK的传输时序：对于PUCCH传输的时隙，UE应在时隙n+K1+Koffset内的PUCCH资源上传输对应的HARQ-ACK信息。
MAC CE激活时序：当包括MAC CE命令的PDSCH对应的HARQ-ACK信息在时隙n上传输，该MAC CE命令指示的对应行为以及UE假设的下行配置应从时隙后的第一个时隙开始生效，其中，X可能由NTN的UE能力确定，取值可以不为3。
CSI参考资源时序：对于在上行时隙n′上上报CSI的CSI参考资源是根据单个下行时隙确定的。
非周期SRS传输时序：如果UE在时隙n上收到DCI触发传输非周期SRS，该UE在时隙上传输每个被触发的SRS资源集合中的非周期SRS。
对于Koffset的配置，网络会通过广播的方式配置小区级的Koffset。对于连接态的UE，网络可以通过MAC为UE配置专属的Koffset。如果网络没有配置UE专属的Koffset，则UE使用广播的Koffset。
为了适配NTN中UE维护的较大的TA，目前NTN针对Uu接口的调度时序进行了增强。对于NTN网络下的SL通信，如果发送方UE被配置为SL资源分配模式1，由于其用于SL传输的资源 完全由其服务基站调度决定，此时发送方UE从接收PDCCH到SL传输的定时或时序(timing)，以及UE从接收到物理侧行反馈信道(Physical Sidelink Feedback Channel，PSFCH)到PUCCH传输的timing，都会因为NTN网络中发送方UE TA的增大而受到影响。在NTN中如何对Uu传输和SL传输之间的timing进行增强，目前没有公开的方案。
