PDCCH监听方法与装置、终端和网络设备 技术领域
本申请涉及通信技术领域，尤其涉及一种PDCCH监听方法与装置、终端和网络设备。
背景技术
第三代合作计划(3rd Generation Partnership Project，3GPP)已经制定关于地面通信(如蜂窝移动通信)的协议标准。在非陆地(non-terrestrial network，NTN)网络中，上下行数据传输定时Timing在现有的传输定时Timing基础上引入K_offset。在NTN通信系统中，终端的定时提前(Timing advance,TA)补偿值是由终端级别的TA值以及网络广播的公共TA值确定，对于网络而言，是不能够确定终端的TA补偿的具体值。由于网络在调度终端进行上行物理共享信道(Physical Uplink Shared Channel，PUSCH)传输时，不知道终端的TA补偿的具体值(即不能确定终端具体发送PUSCH的具体位置)，无法确定终端具体的PUSCH发送时机，进而网络无法精确确定终端能够监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)的时间位置。按照现有陆地网的协议，终端与网络无法在PDCCH的监听位置达成一致，因此，需要引入一种新的数据传输定时规则。

进一步的，终端可以部署在陆地上，包括室内或室外、手持、穿戴或车载；可以部署在水面上(如轮船等)；还可以部署在空中(如飞机、气球和卫星等)。
进一步的，终端可以是手机(mobile phone)、平板电脑、带无线收发功能的电脑、 虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端设备、无人驾驶(self driving)中的车载设备、远程医疗(remote medical)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备或智慧家庭(smart home)中的无线终端设备等。
具体的，本申请实施例中的卫星可以是载有弯管有效载荷(bent pipe payload)或再生有效载荷(regenerative payload)信号发射机的航天器，其通常运行在300至1500km之间的高度的近地轨道(low earth orbit，LEO)、在7000至25000km之间的高度的中地轨道(medium earth orbit，MEO)、在35786km的高度的同步地球轨道(geostationary earth orbit，GEO)或者在400至50000km之间的高度的高椭圆轨道(high elliptical orbit，HEO)。也就是说，卫星按照轨道高度的不同可以为LEO卫星、MEO卫星、GEO卫星或者HEO卫星等。
进一步的，本申请实施例中的卫星发送的信号通常会在以其视场(field of view)为边界的给定服务区域(given service area)上产生一个或多个波束(波束，或者称为波束footprint)。同时，一个波束在地面上的形状可以为椭圆形，而卫星的视场取决于天线和最小仰角等。
具体的，本申请实施例中的非地面网络网关可以是位于地球表面的地球站或网关，并能够提供足够的无线射频(radio freq终端ncy，RF)功率和RF灵敏度以连接卫星。同时，非地面网络网关可以是传输网络层(transport network layer，TNL)节点。

在对本申请实施例提供的PDCCH监听方法进行详细介绍之前，再对本申请所涉及的相关通信技术进行介绍。
1、NTN通信系统
在NTN通信系统中，卫星通常会在地面上产生一个或多个波束(波束，或者称为波束footprint)或者小区，一个小区由一个或者多个波束组成在NTN通信系统中，卫星的运转是基于特定的轨道，其运动是有规律的，因此，由卫星运动所带来的传播时延变化是有规律且可以预测的。
此外，在NTN通信系统中，小区或者波束覆盖范围内对应的最大差分时延值是指：在某一个小区或者波束覆盖范围内，距卫星最远的位置对应的传播时延与距卫星最近的位置对应的传播时延之差，一般来讲，一个小区或者波束覆盖区域对应的最大差分时延，网络设备是能够计算出来的，由于卫星距离地面比较远，导致卫星形成的波束/小区覆盖范围比较大，导致在波束覆盖范围内存在较大的差分时延(同步卫星最大的差分时延值的2倍是20.6ms)。
2、NTN通信系统中的调度时延增强区间的长度值K_offset
在NTN通信系统中，终端在发送上行数据时会基于所获得的时间提前量(timing advance，TA)值，进行提前发送，基于这个原因需要对现有协议中的上下行定时进行增强，即加入一个额外的时间间隔(也即调度时延增强区间的长度值)K_offset。例如，在现有的PDCCH调度PUSCH的过程中，PDCCH中的DCI会指示终端一个调度的时延值(协议称K2)，终端根据指示的K2值确定PUSCH的发送资源位置。然而，由于NTN通信系统中存在很大的传播时延，如果终端需要根据获取的TA值进行提前发送，意味着PDCCH接收时刻与PUSCH发送时刻之间必须有足够大的时间间隔(至少不能小于TA的大小，终端TA的大小可能是卫星与终端之间的来回传播时延)保证终端的提前发送。因此，在NTN通信系统中，PDCCH调度PUSCH的调度时延增强为：K2+K_offset,这样就可以保证PDCCH接收时刻与PUSCH发送时刻之间必须有足够大的时间间隔让终端进行提前发送。
3、NTN中的TA(Timing advance)维护机制
在NTN中，终端可以根据自身位置信息(位置信息由GNSS确定)以及星历信息确定终端到卫星之间的传播时延，这段传播时延称作为终端级别的定时提前量。为了定义Common TA(公共定时提前量)，现有技术引入了参考点，参考点的位置可以是卫星，也可以是地面基站，也可以是服务链路或者反馈链路任何位置。所谓的Common TA为参考点至卫星之间的来回传播时延(Round trip Time，RTT)。终端在进行TA补偿时，TA的取 值需要根据终端自主计算的终端级别的定时提前量以及网络广播的Common TA值确定。
4、重复传输。
为了保证覆盖范围，现有陆地网中NB-IOT/eMTC采用了重复传输的技术。对于下行传输最大的重复次数是2048次，对于上行传输，最大的重复次数为128次。PDSCH/PUSCH的实际重复次数由其对应的调度DCI动态指示，即终端根据DCI中特定的比特域确定PDSCH/PUSCH的重复次数，PDCCH的最大重复次数(即Rmax)由RRC/SIB半静态配置。
5、半频分双工(Freqncy Division Duplexing，FDD)
在半频分双工模式下的终端不能同时进行数据的收发，即不能同时进行数据的接收与发送。
在NTN通信系统中，上下行数据传输定时Timing在现有的传输定时Timing基础上引入K_offset。在NTN通信系统中，终端的定时提前(Timing advance,TA)补偿值是由终端级别的TA值以及网络广播的公共TA值确定，对于网络而言，是不能够确定终端的TA补偿的具体值。由于网络不能知道终端的TA补偿的具体值(即不能确定终端具体发送PUSCH的具体位置)，网络无法精确确定终端能够监听PDCCH的时机。因此，按照现有陆地网的协议，终端在调度时延增强区间会一直执行PUSCH监听。
结合上述描述，本申请实施例提供一种物理下行控制信道PDCCH监听方法的流程示意图，其应用于终端，请参阅图3。该方法包括：
S310、终端获取配置信息。

具体的，该配置信息包括以下其中一种：第一时间窗口的长度值；第二时间窗口的长度值；第三时间窗口的长度值和PUSCH的目标参数阈值。
下面，对第一时间窗口的长度值进行详细介绍。
第一时间窗口的长度值可以是小区或者波束级别。
若第一时间窗口的长度值是小区级别的，即网络设备通过系统广播信息或者RRC信令为小区配置一个第一时间窗口的长度值，此种情况下，第一时间窗口的长度值为网络设备根据终端所在小区对应的最大差分时延确定的。若一个小区包含多个波束，则小区内每个波束覆盖区域均对应同一个第一时间窗口的长度值。
若第一时间窗口的长度值是波束级别的，即网络设备通过系统广播信息或者RRC信令为一个小区中的每个波束配置一个第一时间窗口的长度值，此种情况下，第一时间窗口的长度值为网络设备根据终端所在波束对应的最大差分时延确定的。若一个小区包含多个波束，则小区内每个波束覆盖区域均对应不同的第一时间窗口的长度值。
下面，对第二时间窗口的长度值进行详细介绍。
第二时间窗口的长度值可以是小区或者波束级别。
若第二时间窗口的长度值为小区级别的，即网络设备通过系统广播信息或者RRC信令为小区配置一个第二时间窗口的长度值。此种情况下，第二时间窗口的长度值可以为网络设备根据终端所在的小区对应的，最大差分时延和最大PUSCH传输时长确定的。若一个小 区包含多个波束，则小区内每个波束覆盖区域均对应同一个第二时间窗口的长度值。
若第二时间窗口的长度值为波束级别的，即网络设备通过系统广播信息或者RRC信令为一个小区中的每个波束配置一个第二时间窗口的长度值，此种情况下，第二时间窗口的长度值可以为网络设备根据终端所在的波束对应的，最大差分时延和最大PUSCH传输时长确定的。若一个小区包含多个波束，则小区内每个波束覆盖区域均对应不同的第二时间窗口的长度值。
下面，对第三时间窗口的长度值进行详细介绍。

S320、终端根据配置信息确定第一时间区间，第一时间区间为调度时延增强区间中不需要监听PDCCH的时间区间。
由于配置信息包括的信息存在三种情况，因此，终端根据配置信息确定第一时间区间存在以下三种方式。
方式一：
配置信息包括第一时间窗口的长度值，终端根据配置信息确定第一时间区间，包括：确定第一参考位置；根据下行控制信息DCI确定第一时间间隔以及所述DCI调度的物理上行共享信道PUSCH传输时长；根据第一参考位置和第一时间间隔，确定第一时间区间的起始位置，起始位置为第一参考位置和第一时间间隔的和值；根据起始位置、第一时间窗口的长度值和PUSCH传输时长，确定第一时间区间的结束位置，结束位置为起始位置、第一时间窗口的长度值和PUSCH传输时长的和值减去1个时间单位。
具体的，PUSCH传输包括上行数据传输或者下行数据对应的HARQ-ACK信息传输。
具体的，PUSCH传输时长的获取方式可以是：终端根据DCI中的PUSCH调度信息以及时隙配置等信息确定该PUSCH传输时长，也即，终端即根据DCI指示的重复传输次数、资 源配置指示、调度TB数指示等确定PUSCH传输时长。
具体的，本申请实施例所涉及的时间单位可以但不限于是毫秒(ms)、子帧(subframe)、帧(frame)、时隙(slot)中的一种，对此不作具体限制。
方式二：
配置信息包括第二时间窗口的长度值，终端根据配置信息确定第一时间区间包括：确定第一参考位置；根据下行控制信息DCI确定第一时间间隔；根据第一参考位置和第一时间间隔，确定第一时间区间的起始位置，起始位置为第一参考位置和第一时间间隔的和值；根据起始位置和第二时间窗口的长度值确定第一时间区间的结束位置，结束位置为起始位置与第二时间窗口的长度值减去1个时间单位。
方式三：

具体的，所述PUSCH的目标参数包括PUSCH传输时长或者PUSCH重复传输次数。
具体的，所述PUSCH的目标参数阈值包括PUSCH传输时长阈值或者PUSCH重复传输次数阈值。
可以理解的是，当PUSCH的目标参数为PUSCH传输时长时，PUSCH的目标参数阈值为PUSCH传输时长阈值，当PUSCH的目标参数为PUSCH重复传输次数时，PUSCH的目标参数阈值为PUSCH重复传输次数。
其中，PUSCH传输时长的获取方式可以是：终端根据DCI中的PUSCH调度信息以及时隙配置等信息确定该PUSCH传输时长，也即，终端即根据DCI指示的重复传输次数、资源配置指示、调度TB数指示等确定PUSCH传输时长。
其中，PUSCH重复传输次数的获取方式可以是：终端根据所述DCI中的比特域确定PUSCH重复传输次数。
具体的，在方式一、方式二以及方式三中，第一参考位置和第一时间间隔的之间对应关系是相同的，由于第一参考位置有不同的情况，因此第一参考位置和第一时间间隔的之间对应关系存在以下两种情形：
情形一：
若第一参考位置为承载该DCI的PDCCH监听时机的结束位置，则第一时间间隔为所述PDCCH监听时机对应的DCI所调度的PUSCH传输对应的调度时延。
情形二：
若第一参考位置为所述DCI所调度的物理下行共享信道PDSCH传输的结束位置，则第一时间间隔为第一参考位置与PDSCH传输对应的混合自动重传请求应答HARQ-ACK传输的调度时延。
在一个可能的示例中，根据配置信息确定第一时间区间之后，方法还包括：确定启动PDCCH监听的起始位置为第一时间区间的结束位置加上1个时间单位。
可见，本示例中，终端能够根据配置信息确定调度时延增强区间中需要进行PDCCH监听的起始位置，以避免终端在该调度时延增强区间执行无效的PDCCH监听，进而减少终端的能耗。
在一个可能的示例中，确定启动PDCCH监听的起始位置为第一时间区间的结束位置加上1个时间单位之后，方法还包括：确定执行PDCCH监听的结束位置为调度时延增强区间的结束位置减去一个时间单位。
可见，本示例中，终端能够根据配置信息确定调度时延增强区间中需要进行PDCCH监听的起始位置和结束位置，以维系NTN通信系统吞吐量。

其中，K_offset为网络设备配置的。
可见，本示例中，终端能够获取网络设备配置的K_offset。
本申请所涉及的终端包括终端，本申请所涉及的网络设备包括网络设备。
下面，对本申请实施例方法的应用场景进行示例性说明。
应用场景实施例1：
在NTN通信系统中，终端的TA补偿值是由终端级别的TA值以及网络广播的公共TA值确定，对于网络设备而言，是不能够确定终端的TA补偿的具体值。由于网络设备不能知道终端的TA补偿的具体值(即不能确定终端具体发送PUSCH的具体位置)，网络设备无法精确确定终端能够监听PDCCH的时机。但是，网络设备可以根据终端当前所处的小区或者波束确定终端补偿值的范围，即根据终端当前所处的终端覆盖区域的最低点(即距离卫星最远的位置)以及最高点(即距离卫星最近的位置)与卫星之间的来回传播时延确定出终端TA补偿值的范围，进而可以确定出终端发送PUSCH的时间区间。
因此，网络设备能够根据终端TA补偿值的范围以及DCI调度的PUSCH(可以是上行数据或者下行数据对应的HARQ-ACK信息)传输时长，确定终端发送PUSCH的时间范围，网络设备下发的PDCCH到达终端的时间是不能够落在终端发送PUSCH的时间范围内的，相当于，终端在网路设备所确定的发送PUSCH的时间范围内是不需要监听PDCCH的。
由于终端TA补偿值的取值区间跨度与终端所在小区或者波束对应的最大差分时延相关，意味着终端发送完PUSCH后，一段时间内(最差的情况是终端最大差分时延的2倍)是监听不到PDCCH的。
在NTN通信系统中，上下行数据传输定时Timing在现有的传输定时Timing基础上引入K_offset后，如图4所示出的，终端通过无线资源控制RRC信令或者系统广播信息接收网络设备配置的K_offset。终端通过无线资源控制RRC信令或者系统广播信息接收网络设备配置的第一时间窗口的长度值T。终端根据DCI中的PUSCH调度信息以及时隙配置等信息确定该PUSCH(包括上行数据或者下行数据对应的HARQ-ACK信息)传输时长N。
若所述第一参考位置n为承载所述DCI的PDCCH监听时机的结束位置，且所述第一时间间隔k为所述DCI所调度的PUSCH传输对应的调度时延情况下，该第一时间窗口的起始位置固定为n+k。n+k至n+k+K_offset为调度时延增强区间。n+k到n+k+T+N-1不需要监听PDCCH。具体实现中，终端在该n+k到n+k+T+N-1不进行PDCCH监听，以保证终端与网络在PDCCH监听位置上达成一致，同时，能减少终端能耗。进一步的，n+k+T+N为终端发送完PUSCH后，启动PDCCH监听的起始位置，n+K_offset+k-1为该PDCCH监听的结束位置。具体实现中，终端在n+k+T+N至n+K_offset+k-1进行PDCCH监听，能够维系NTN通信系统吞吐量。
其中，T可以是小区级别的，即网络设备通过系统广播信息或者RRC信令为小区配置一个T，若一个小区包含多个波束，则小区内每个波束覆盖区域均对应同一个T。T也可以是波束级别的，即网络设备通过系统广播信息或者RRC信令为一个小区中的每个波束配置一个T，若一个小区包含多个波束，则小区内每个波束覆盖区域均对应不同的T。具体的，网络设备可以通过RRC专用信令或者系统广播信息给终端配置T。进一步的，T是网络设备根据终端所在波束或者小区对应的最大差分时延确定的。
N为DCI调度的PUSCH传输时长。PUSCH传输包括上行数据传输或者下行数据对应的HARQ-ACK信息传输。终端可以根据DCI中的PUSCH调度信息以及时隙配置等信息确定N，即终端根据DCI中指示的PUSCH重复传输次数、资源配置指示、调度字节数指示确定N。
k的单位可以但不限于是毫秒、子帧、帧、时隙中的一种。若n为子帧号，则k、K_offset、T、N的单位均为子帧，若n为子时隙号，则k、K_offset、T、N的单位均为时隙。
具体的，当T为小区级别时，所述最大差分时延为第一传播时延和第二传播时延之间的传播时延差值；所述第一传播时延为第一位置与目标设备所在位置之间的传播时延，所述第一位置为所述终端所在小区覆盖区域中，距离目标设备最近的位置；或者，所述第一位置为终端所在小区的波束覆盖区域中，距离所述目标设备最近的位置，所述目标设备为卫星或者所述网络设备；所述第二传播时延为第二位置与所述目标设备所在位置之间的传播时延，所述第二位置为所述终端所在小区覆盖区域中，距离所述目标设备最远的位置；或者，所述第二位置为所述终端所在小区的波束覆盖区域中，距离所述目标设备最远的位置。
具体的，当T为波速级别时，所述最大差分时延为第一传播时延和第二传播时延之间的传播时延差值；所述第一传播时延为第一位置与目标设备所在位置之间的传播时延，所述第一位置为所述终端所在波速覆盖区域中，距离目标设备最近的位置；或者，所述第一位置为终端所在波速的波束覆盖区域中，距离所述目标设备最近的位置，所述目标设备为卫星或者所述网络设备；所述第二传播时延为第二位置与所述目标设备所在位置之间的传播时延，所述第二位置为所述终端所在波速覆盖区域中，距离所述目标设备最远的位置；或者，所述第二位置为所述终端所在波速的波束覆盖区域中，距离所述目标设备最远的位置。
需要说明的是，第二条件的应用原理和第一条件的应用原理相同，针对第二条件的描述参考前述针对第一条件的描述，此处不再赘述，第二条件包括n为所述DCI所调度的物理下行共享信道PDSCH传输的结束位置，且k为n与PDSCH传输对应的HARQ-ACK传输的 调度时延，第一条件所述第一参考位置n为承载所述DCI的PDCCH监听时机的结束位置，且所述第一时间间隔k为所述DCI所调度的PUSCH传输对应的调度时延。
应用场景实施例2：
在NTN通信系统中，终端的TA补偿值是由终端级别的TA值以及网络广播的公共TA值确定，对于网络设备而言，是不能够确定终端的TA补偿的具体值。由于网络设备不能知道终端的TA补偿的具体值(即不能确定终端具体发送PUSCH的具体位置)，网络设备无法精确确定终端能够监听PDCCH的时机。但是，网络设备可以根据终端当前所处的小区或者波束确定终端补偿值的范围，即根据终端当前所处的终端覆盖区域的最低点(即距离卫星最远的位置)以及最高点(即距离卫星最近的位置)与卫星之间的来回传播时延确定出终端TA补偿值的范围，进而可以确定出终端发送PUSCH的时间区间。
此外，在NTN通信系统中，网络设备会通过系统广播信息或者RRC专用信令配置小区级别的最大PUSCH(可以是上行数据或者下行数据对应的HARQ-ACK信息)重复传输次数(一个小区对应一个最大PUSCH重复传输次数)，或者，配置波束级别的最大PUSCH重复传输次数(即一个波束对应一个最大PUSCH重复传输次数)。因此，网络设备能够根据终端TA补偿值的范围以及当前终端所在的小区或者波束对应的最大PUSCH传输时长，确定终端发送PUSCH的时间范围，网络设备下发的PDCCH到达终端的时间是不能够落在的终端发送PUSCH的时间范围内的。相当于，终端在网路设备所确定的发送PUSCH的时间范围内是不需要监听PDCCH的。
由于终端TA补偿值的取值区间跨度与当前小区或者波束对应的最大差分时延相关，意味着终端发送完上行数据后，一段时间内(最差的情况是最大差分时延的2倍)是监听不到PDCCH信息的。
在NTN通信系统中，上下行数据传输定时Timing在现有的传输定时Timing基础上引入K_offset后，如图5所示出的，终端通过无线资源控制RRC信令或者系统广播信息接收网络设备配置的K_offset。终端通过无线资源控制RRC信令或者系统广播信息接收网络设备配置的第二时间窗口的长度值T1。
若所述第一参考位置n为承载所述DCI的PDCCH监听时机的结束位置，且所述第一时间间隔k为所述DCI所调度的PUSCH传输对应的调度时延的情况下，所述第二时间窗口的起始位置固定为n+k。n+k至n+k+K_offset为调度时延增强区间。n+k到n+k+T1-1不需要监听PDCCH。具体实现中，终端在该n+k到n+k+T1-1不进行PDCCH监听，以保证终端与网络在PDCCH监听位置上达成一致，同时，能减少终端能耗。n+k+T1为终端发送完PUSCH后，启动PDCCH监听的起始位置，n+K_offset+k-1为该PDCCH监听的结束位置。具体实现中，终端在n+k+T1至n+K_offset+k-1区间进行PDCCH监听，能够维系NTN通信系统吞吐量。
其中，T1可以是小区级别的，即网络设备通过系统广播信息或者RRC信令为小区配置一个T1，若一个小区包含多个波束，则小区内每个波束覆盖区域均对应同一个T1。T1也可以是波束级别的，即网络设备通过系统广播信息或者RRC信令为一个小区中的每个波束配置一个T1，若一个小区包含多个波束，则小区内每个波束覆盖区域均对应不同的T1。具体的，网络设备可以通过RRC专用信令或者系统广播信息给终端配置T1。进一步的，T1 是网络设备根据终端所在小区或者波束对应的最大差分时延以及终端所在小区或者波束对应的最大PUSCH(可以是上行数据或者下行数据对应的HARQ-ACK信息)传输时长确定的。
可以理解的是，如果第二时间窗口是波束级别的，则对应的最大PUSCH传输时长也是波束级别的，如果第二时间窗口是小区级别的，则对应的最大PUSCH传输时长也是小区级别的。
k的单位可以但不限于是毫秒、子帧、帧、时隙中的一种。若n为子帧号，则k、K_offset、T1的单位均为子帧，若n为子时隙号，则k、K_offset、T1的单位均为时隙。
具体的，当T1为小区级别时，所述最大差分时延为第一传播时延和第二传播时延之间的传播时延差值；所述第一传播时延为第一位置与目标设备所在位置之间的传播时延，所述第一位置为所述终端所在小区覆盖区域中，距离目标设备最近的位置；或者，所述第一位置为终端所在小区的波束覆盖区域中，距离所述目标设备最近的位置，所述目标设备为卫星或者所述网络设备；所述第二传播时延为第二位置与所述目标设备所在位置之间的传播时延，所述第二位置为所述终端所在小区覆盖区域中，距离所述目标设备最远的位置；或者，所述第二位置为所述终端所在小区的波束覆盖区域中，距离所述目标设备最远的位置。
具体的，当T1为波速级别时，所述最大差分时延为第一传播时延和第二传播时延之间的传播时延差值；所述第一传播时延为第一位置与目标设备所在位置之间的传播时延，所述第一位置为所述终端所在波速覆盖区域中，距离目标设备最近的位置；或者，所述第一位置为终端所在波速的波束覆盖区域中，距离所述目标设备最近的位置，所述目标设备为卫星或者所述网络设备；所述第二传播时延为第二位置与所述目标设备所在位置之间的传播时延，所述第二位置为所述终端所在波速覆盖区域中，距离所述目标设备最远的位置；或者，所述第二位置为所述终端所在波速的波束覆盖区域中，距离所述目标设备最远的位置。
需要说明的是，第二条件的应用原理和第一条件的应用原理相同，针对第二条件的描述参考前述针对第一条件的描述，此处不再赘述，第二条件包括n为所述DCI所调度的物理下行共享信道PDSCH传输的结束位置，且k为n与PDSCH传输对应的HARQ-ACK传输的调度时延，第一条件所述第一参考位置n为承载所述DCI的PDCCH监听时机的结束位置，且所述第一时间间隔k为所述DCI所调度的PUSCH传输对应的调度时延。

因此，网络设备能够根据终端TA补偿值的范围以及DCI调度的PUSCH(可以是上行 数据或者下行数据对应的HARQ-ACK信息)传输时长(或者重复传输次数)阈值，配置第三时间窗口的长度值T2，保证满足一定条件的上行数据调度的实际发送位置落在第三时间窗口。
在NTN通信系统中，上下行数据传输定时Timing在现有的传输定时Timing基础上引入K_offset之后，如图6所示出的，终端通过无线资源控制RRC信令或者系统广播信息接收网络设备配置的K_offset。终端通过无线资源控制RRC信令或者系统广播信息接收网络设备配置的第三时间窗口的长度值T2和PUSCH的目标参数阈值，所述PUSCH的目标参数阈值包括PUSCH传输时长阈值或者PUSCH重复传输次数阈值。
