具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
本文所描述的技术不限于第五代移动通信(5th-generation，5G)系统以及后续演进通信系统，以及不限于LTE/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(TimeDivision Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。
本发明实施例提供的终端可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(PersonalDigital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。
非地面网络(Non-Terrestrial Network，NTN)指的是将卫星通信与5G相融合形成海陆空一体化通信网，以便为5G业务提供所需的关键性能，例如卫星可以为地面5G网络无法覆盖的偏远地区、飞机或轮船等提供经济可靠的网络服务，提高5G网络覆盖率；卫星可以为飞机、轮船、高铁等移动终端提供连续不间断的网络连接，增强5G网络的服务能力；卫星的广播/多播能力可以为网络边缘终端提供高效的数据分发服务能力。
现今，物联网行业需求越来越大，其中基于蜂窝的窄带物联网(NB-IoT,Narrow Band Internet of Things)和增强机器类通信(eMTC，enhanced Machine-Type Communication)为物联网领域最具潜力的两项技术，而它们通常需要通过卫星连接才能提供覆盖。非地面网络的传播时延比较大而卫星的快速运动更导致传播时延的快速变化。为了增强覆盖能力，NB-IoT/eMTC引入了重复传输机制。然而，在NB-IoT/eMTC的重复传输机制中，只在整个持续传输过程的初始时间进去定时提前量的确定。这种NB-IoT/eMTC上行同步机制，不能适应持续传输过程中传播时延的快速变化，容易造成上行多用户之间的干扰。
鉴于此，本公开提供了一种定时提前量确定方法和设备，根据指示的多个定时提前量或多个定时提前量的计算参数确定持续传输过程中的每段传输的定时提前量。
图1示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。在本实施例中，方法由终端执行，如图1所示，该定时提前量确定方法包括以下步骤：
S101，接收与持续传输过程对应的定时提前量TA(time advance)信息，其中所述定时提前量信息指示多个定时提前量的信息，例如包括多个定时提前量的值或多个定时提前量的计算参数。
该定时提前量信息可以是非地面网络的网络设备根据卫星的变化，例如其运动轨迹、移动速度、方向等信息预先确定的信息。例如，根据卫星的运动轨迹可以知晓卫星在某个持续传输过程中移动情况，由此可以确定该移动情况对于持续传输过程中的传播时延的影响，从而可以确定定时提前量信息，该定时提前量信息可以指示多个定时提前量或多个定时提前量的计算参数，因此能够反映终端在每段传输时使用的定时提前量随着持续传输过程中的不同传播时延的变化。
S102，根据所述定时提前量信息确定所述持续传输过程中的每段传输的定时提前量。
在本公开的实施例中，通过获取与持续传输过程对应的定时提前量信息、并根据该定时提前量信息确定持续传输过程中每段传输的定时提前量，从而能够适于传播时延的快速变化而对每段传输的定时提前量进行修正，从而能够避免在持续传输过程中由于传播时延的快速变化而造成的上行多用户之间的干扰。
图2示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。在本实施例中，方法由终端执行，如图2所示，该定时提前量确定方法包括以下步骤：
S201，接收与持续传输过程对应的定时提前量信息，定时提前量信息包括与持续传输过程对应的多个定时提前TA值。
该定时提前量信息可以是非地面网络的网络设备根据卫星的变化，例如其运动轨迹、移动速度、方向等信息预先确定的信息。例如，根据卫星的运行轨迹，可以确定卫星在某个持续传输过程中以一定速度远离地球移动。在这种情况下，可以确定在该持续传输过程中，传播时延以一定变化率变大，相应地，则终端在持续传输过程中使用的定时提前量也应以一定变化率变大。在本实施例中，可以根据传播时延 的变化情况，确定多个TA值，每个TA值指示一个定时提前量。在上述情况下，终端可以接收一组TA值，该组TA值可以是一组递增的TA值，例如为3、4、5、6、7…。然而，根据不同情况，该组TA值也可以是递减的。此外，该组TA值可以为一组等差值或非等差值，本实施例对此并不限制。
S202，根据多个TA值的数量和持续传输过程的总时间，确定每个TA值对应的时间间隔。
在接收到多个TA值之后，终端可以根据TA值的数量以及持续传输过程的总时间，确定每个TA值对应的时间间隔。例如，终端接收到的该组TA值包括6个值，而总时间假设为120μs(在此仅为清楚说明而假设该值，在实际情况中，该时间值可能更小或者更大)，则表明每个TA值对应的时间间隔为20μs。
S203，根据多个TA值和每个TA值对应的时间间隔，确定每段传输的定时提前量。
在确定了每个TA值的对应时间间隔之后，可以确定每段传输的定时提前量。
如上所述示例，假定该组TA值为3、4、5、6、7、8，而每个TA值对应的时间间隔为20μs，则可以确定在0-20μs内进行的每段传输的TA值为3，根据该TA值3可以确定0-20μs内的每段传输的定时提前量；20-40μs内进行的每段传输的TA值为4，根据该TA值4可以确定20-40μs内的每段传输的定时提前量；以此类推，可以分别确定40-60μs、60-80μs、80-100μs以及100μs-120μs内的每段传输所使用的的TA值分别为5、6、7、8，由此，可以确定每个时间间隔内的每段传输的定时时间量。
在本公开的实施例中，通过获取与持续传输过程对应的多个TA值、并根据该多个TA值直接确定每段传输对应的TA值，从而能够确定每段传输的定时提前量，因此持续传输过程中的每段传输的定时提前量并非固定不变的，从而能够避免在持续传输过程中由于固定定时提前量无法适应传播时延的快速变化而造成的上行多用户之间的干扰。
在上述过程的步骤S202中，根据多个TA值的数量和持续传输过程的总时间确定每个TA值对应的时间间隔，其中默认为每个TA值对应的时间间隔是相等的，即在整个持续传输过程中，以固定的时间间隔改变TA值。在一些实施例中，定时提前量信息还包括每个TA值对应的时间间隔。当定时提前量信息包括每个TA值对应的时间间隔时，上述过程中的步骤S202可以省略。定时提前量信息中所包括的每个TA值对应的时间间隔可以是相同的也可以是不同的，当为相同的时，表明以固定的时间间隔改变TA值，如上所示示例；当为不同的时，表明可以以不同的时间间隔改变TA值。例如，如上示例中的6个TA值对应的时间间隔可以分别为0-10μs、10-30μs、30-60μs、60-90μs、90-110μs、110μs-120μs。在这种情况下，可以确定在0-10μs内进行的每段传输的TA值为3，根据该TA值3可以确定0-10μs内的每段传输的定时提前量；10-30μs内进行的每段传输的TA值为4，根据该TA值4可以确定10-30μs内的每段传输的定时提前量；30-60μs内进行的每段传输的TA值为5，根据该TA值5可以确定30-60μs内的每段传输的定时提前量；以此类推，可以分别确定60-90μs、90-110μs以及110μs-120μs内的每段传输所使用的的TA值分别为6、7、8。在该示例中，以不同的时间间隔改变TA值，这可以适应于例如卫星以变化的速度移动，例如卫星在0μs-10μs移动较快，而在30μs-60μs移动较慢，因此TA值在0-10μs的10μs内就发生变化增幅为1，而在30-60μs的30μs的时间内也发生变化增幅为1。
图3示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。在本实施例中，方法由终端执行，如图3所示，该定时提前量确定方法包括以下步骤：
S301，接收与持续传输过程对应的定时提前量信息，定时提前量信息包括初始定时提前TA值、调整时间间隔以及第一调整增量，其中所述第一调整增量指示对初始TA值进行调整的增量。
该定时提前量信息可以是非地面网络的网络设备根据卫星的变化，例如其运动轨迹、移动速度、方向等信息预先确定的信息。例如，根据卫星的运行轨迹，可以确定卫星在某个持续传输过程中以一定速度远离地球移动。在这种情况下，可以确定在该持续传输过程中，传播时延以一定变化率变大，相应地，则终端在持续传输过程中使用的定时提前量也应以一定变化率变大。在本实施例中，可以根据传播时延的变化情况，确定初始定时提前TA值、调整时间间隔以及第一调整增量，该第一调整增量可以为正值也可以为负值，当为正值时，表明TA值为递增的，当为负值时，表明TA值为递减的。例如，终端可以接收初始TA值为3，调整时间间隔为20μs，第一调整增量为1。
S302，根据初始TA值、调整时间间隔、第一调整增量以及持续传输过程的总时间，计算与持续传输过程对应的多个TA值。
在接收到初始TA值、调整时间间隔、第一调整增量之后，终端可以根据调整时间间隔以及持续传输过程的总时间，确定与持续传输过程对应的TA值的数量，然后终端可以根据初始TA值以及第一调整增量，确定与持续传输过程对应的多个TA值。
如上示例，假设总时间为120μs，则根据调整时间间隔20μs，可以确定6个TA值，而根据初始TA值3以及第一调整增量1，可以确定该6个TA值分别为3、4、5、6、7、8。
S303，根据多个TA值和调整时间间隔，确定每段传输的定时提前量。
在确定了每个TA值之后，可以确定每段传输的定时提前量。
如上所述示例，确定6个TA值：3、4、5、6、7、8，而调整时间间隔为20μs，则可以确定在0-20μs内进行的每段传输的TA值为3，根据该TA值3可以确定0-20μs内的每段传输的定时提前量；20-40μs内进行的每段传输的TA值为4，根据该TA值4可以确定20-40μs内的每段传输的定时提前量；以此类推，可以分别确定40-60μs、60-80μs、80-100μs以及100μs-120μs内的每段传输所使用的的TA值分别为5、6、7、8，由此，可以确定每个时间间隔内的每段传输的定时时间量。
在本公开的实施例中，通过获取与持续传输过程对应的初始TA值、调整时间间隔、第一调整增量并根据该初始TA值、调整时间间隔、第一调整增量确定每段传输对应的TA值，从而能够确定每段传输的定时提前量，相比于传输多个TA值，在本实施例中可以减少传输数据量。
图4示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。在本实施例中，方法由终端执行，如图4所示，该定时提前量确定方法包括以下步骤：
S401，接收与持续传输过程对应的定时提前量信息，定时提前量信息包括初始定时提前TA值、初始调整时间间隔、第一调整增量以及第二调整增量，其中所述第一调整增量指示对初始TA值进行调整的增量，所述第二调整增量指示对初始调整时间间隔进行调整的增量。
该定时提前量信息可以是非地面网络的网络设备根据卫星的变化，例如其运动轨迹、移动速度、方向等信息预先确定的信息。例如，根据卫星的运行轨迹，可以确定卫星在某个持续传输过程中以变化的速度远离地球移动。在这种情况下，可以确定在该持续传输过程中，传播时延以可变的变化率变大，相应地，则终端在持续传输过程中使用的定时提前量也应以可变的变化率变大。在本实施例中，可以根据传播时延的变化情况，确定初始定时提前TA值、初始调整时间间隔、第一调整增量以及第二调整增量，该第一调整增量可以为正值也可以为负值，当为正值时，表明TA值为递增的，当为负值时，表明TA值为递减的；该第二调整增量可以为正值也可以为负值，当为正值时，表示调整时间间隔递增，当为负值时，表明调整时间间隔递减。例如，终端可以接收初始TA值为3，初始调整时间间隔为10μs，第一调整增量为1以及第二调整增量为5μs。
S402，根据初始调整时间间隔、第二调整增量以及持续传输过程的总时间，计算在持续传输过程中的多个时间间隔。
在接收到初始调整时间间隔、第二调整增量之后，终端可以根据初始调整时间间隔、第二调整增量以及持续传输过程的总时间，确定与持续传输过程对应的多个时间间隔。
如上示例，假设总时间为120μs，则根据初始调整时间间隔10μs和第二调整增量5μs，可以确定6个时间间隔分别为0-10μs、10μs-25μs、25μs-45μs、45μs-70μs、70μs-100μs以及100μs-120μs，其中调整时间间隔分别为10μs、15μs、20μs、25μs、30μs，即调整时间间隔以第二调整增量5μs递增。由于100μs+35μs(30μs之后的下一调整时间间隔)超出总时间，因此最后时间间隔被设置为100μs-120μs。
S403，根据初始TA值、多个时间间隔的数量、以及第一调整增量，计算与持续传输过程对应的多个TA值。
在确定多个时间间隔之后，终端可以根据初始TA值、多个时间间隔的数量、以及第一调整增量，确定算与持续传输过程对应的多个TA值。
如上示例，由于确定了6个时间间隔，由此需要确定6个TA值，根据初始TA值3以及第一调整增量1，可以确定该6个TA值分别为3、4、5、6、7、8。
S404，根据多个TA值和多个时间间隔，确定每段传输的定时提前量。
在确定了每个TA值之后，可以确定每段传输的定时提前量。
如上所述示例，确定6个时间间隔分别为0-10μs、10μs-25μs、25μs-45μs、45μs-70μs、70μs-100μs以及100μs-120μs，而6个TA值分别为3、4、5、6、7、8，则可以确定在0-10μs内进行的每段传输的TA值为3，根据该TA值3可以确定0-10μs内的每段传输的定时提前量；10-25μs内进行的每段传输的TA值为4，根据该TA值4可以确定10-25μs内的每段传输的定时提前量；以此类推，可以分别确定25-45μs、45-70μs、70-100μs以及100μs-120μs内的每段传输所使用的的TA值分别为5、6、7、8，由此，可以确定每个时间间隔内的每段传输的定时时间量。
在本公开的实施例中，通过获取与持续传输过程对应的初始TA值、初始调整时间间隔、第一调整增量以及第二调整增量并根据该初始TA值、初始调整时间间隔、第一调整增量以及第二调整增量确定每段传输对应的TA值，从而能够适应于传播时延以可变变换率发生变化的情况。
图5示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。本实施例基于以上参考图1-图4所述的任意一个实施例，在本实施例中，方法由终端执行，如图5所示，该定时提前量确定方法包括以下步骤：
S501，接收与持续传输过程对应的定时提前量信息，其中所述定时提前量信息指示多个定时提前量的信息，例如包括多个定时提前量的值或多个定时提前量的计算参数。
S502，根据所述定时提前量信息确定所述持续传输过程中的每段传输的定时提前量。
S503，对于每段传输，当根据本段传输的定时提前量、上一段传输的定时提前量以及传输时间确定本段传输的起始时间早于上一段传输的结束时间时，放弃本段传输的初始上行信号(即应在重叠时间段传输的初始上行信号)的传输或者放弃上一段末尾上行信号(即尚未完成传输的上行信号)的传输。
由于持续传输过程中定时提前量出现了变化，这有可能导致信号冲突的情况，例如，假设需要进行6段传输，每段传输所需的传输时间为4μs，根据定时提前量信息确定每段传输的定时提前量为1μs、2μs、4μs、5μs、4μs、7μs，针对每段传输的同步时间点(即基站期望接收到终端发送的上行信号的时间点)分别为5μs、10μs、15μs、20μs、25μs、30μs，则每段传输的起始时间点分别为4μs、8μs、11μs、15μs、21μs、23μs，而每段传输的结束时间分别为8μs、12μs、15μs、19μs、25μs、27μs。其中，第三段传输的起始时间11μs早于第二段传输的结束时间12μs，以及第六段传输的起始时间23μs早于第五段传输的结束时间25μs。也就是说，当第二段传输还没结束时，第三段传输已经开始，以及当第五段传输还没有结束时，第六段传输已经开始。因此，第二段传输和第三段传输出现了信号冲突以及第五段传输和第六段传输发生了信号冲突。为了解决这种冲突，终端可以将引发冲突的后一段传输的初始信号丢弃，即放弃传输该部分初始信号。如上示例，在第三段传输中，放弃前一毫秒(11μs-12μs)的初始信号的传输，在第六段传输中，放弃前两毫秒(23μs-25μs)的初始信号的传输。或者，终端可以将引发冲突的前一段传输的末尾信号丢弃，即放弃传输该部分末尾信号。如上示例，在第二段传输中，放弃后一毫秒(11μs-12μs)的末尾信号的传输，在第五段传输中，放弃后两毫秒(23μs-25μs)的末尾信号的传输。具体实现方式可以预先设置或者由基站指示。例如，基站可以额外发送关于冲突解决机制的信息，即在该信息中指示放弃发生冲突的前一段传输的末尾信号的传输还是放弃发生冲突的后一段传输的初始信号的传输。
在本实施例中，当发生信号冲突时，通过放弃发送时间重叠的部分上行信号的传输来解决该冲突。
图6示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。本实施例基于以上参考图1-图4所述的任意一个实施例，在本实施例中，方法由终端执行，如图6所示，该定时提前量确定方法包括以下步骤：
S601，接收与持续传输过程对应的定时提前量信息，其中所述定时提前量信息指示多个定时提前量的信息，例如包括多个定时提前量的值或多个定时提前量的计算参数。
S602，根据定时提前量信息和预配置保护间隔，确定每段传输的定时提前量，使得每段传输的起始时间不早于上一段传输的结束时间。
在一些实施例中，为了避免如上所述的信号冲突，可以通过设置保护间隔的方式实现。例如，可以在每段传输中设置保护间隔为2μs来避免信号冲突。在如上所示示例中，在保护间隔为2μs的情况下，每段传输的同步时间点(即基站期望接收到终端发送的上行信号的时间点)分别为5μs、12μs、19μs、26μs、33μs、40μs，则每段传输的起始时间点分别为4μs、10μs、15μs、21μs、29μs、33μs，而每段传输的结束时间分别为8μs、14μs、19μs、25μs、33μs、37μs。由于保护间隔的存在，解决了如上所述的冲突问题。
在本实施例中，保护间隔预配置在终端，但在其他实施例中，该保护间隔的信息也可以接收自基站，包括预配置保护间隔的配置周期、起始偏移以及持续时间。
在本实施例中，通过设置保护间隔，避免了信号冲突的发生。
图7示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。在本实施例中，方法由基站执行，如图7所示，该定时提前量确定方法包括以下步骤：
S701，向终端发送与持续传输过程对应的定时提前量信息，以使得终端根据所述定时提前量信息确定持续传输过程中的每段传输的定时提前量，其中所述定时提前量信息指示多个定时提前量的信息，例如包括多个定时提前量的值或多个定时提前量的计算参数。
该定时提前量信息可以是非地面网络的网络设备根据卫星的变化，例如其运动轨迹、移动速度、方向等信息预先确定的信息。例如，根据卫星的运动轨迹可以知晓卫星在某个持续传输过程中移动情况，由此可以确定该移动情况对于持续传输过程中的传播时延的影响，从而可以确定定时提前量信息，该定 时提前量信息可以指示多个定时提前量或多个定时提前量的计算参数，因此能够反映终端在每段传输时使用的定时提前量随着持续传输过程中的不同传播时延的变化。
在本公开的实施例中，通过向终端发送定时提前量信息使得终端可以根据该定时提前量信息确定持续传输过程中每段传输的定时提前量，从而能够适于传播时延的快速变化而对每段传输的定时提前量进行修正，从而能够避免在持续传输过程中由于传播时延的快速变化而造成的上行多用户之间的干扰。
在一些实施例中，定时提前量信息包括与持续传输过程对应的多个定时提前TA值。基站向终端发送该多个定时提前TA值，而终端在接收到该多个定时提前TA值后，终端可以根据该多个TA值以及持续传输过程的总时间确定每段传输的定时提前量。该多个TA值可以是一组递增的TA值，例如为3、4、5、6、7、8，而总时间假设为120μs，则终端可以确定在0-20μs内进行的每段传输的TA值为3，根据该TA值3可以确定0-20μs内的每段传输的定时提前量；20-40μs内进行的每段传输的TA值为4，根据该TA值4可以确定20-40μs内的每段传输的定时提前量；以此类推，可以分别确定40-60μs、60-80μs、80-100μs以及100μs-120μs内的每段传输所使用的的TA值分别为5、6、7、8，由此，可以确定每个时间间隔内的每段传输的定时时间量。然而，根据不同情况，该组TA值也可以是递减的。此外，该组TA值可以为一组等差值或非等差值，本实施例对此并不限制。
在一些实施例中，定时提前量信息包括与持续传输过程对应的多个定时提前TA值以及每个TA值对应的时间间隔。基站向终端发送该多个定时提前TA值以及每个TA值对应的时间间隔，而终端在接收到该多个定时提前TA值以及每个TA值对应的时间间隔后，终端可以根据该多个TA值及其对应的时间间隔确定每段传输的定时提前量。例如，如上示例中的6个TA值对应的时间间隔可以分别为0-10μs、10-30μs、30-60μs、60-90μs、90-110μs、110μs-120μs。在这种情况下，终端可以确定在0-10μs内进行的每段传输的TA值为3，根据该TA值3可以确定0-10μs内的每段传输的定时提前量；10-30μs内进行的每段传输的TA值为4，根据该TA值4可以确定10-30μs内的每段传输的定时提前量；30-60μs内进行的每段传输的TA值为5，根据该TA值5可以确定30-60μs内的每段传输的定时提前量；以此类推，可以分别确定60-90μs、90-110μs以及110μs-120μs内的每段传输所使用的的TA值分别为6、7、8。
在一些实施例中，定时提前量信息包括初始定时提前TA值、调整时间间隔以及第一调整增量，其中所述第一调整增量指示对初始TA值进行调整的增量。基站向终端发送该初始TA值、调整时间间隔以及第一调整增量，而终端在接收到该初始TA值、调整时间间隔以及第一调整增量后，终端可以根据初始TA值、调整时间间隔、第一调整增量以及持续传输过程的总时间，确定每段传输的定时提前量。例如，初始TA值为3，调整时间间隔为20μs，第一调整增量为1，而总时间假设为120μs，则终端可以确定在0-20μs内进行的每段传输的TA值为3，根据该TA值3可以确定0-20μs内的每段传输的定时提前量；20-40μs内进行的每段传输的TA值为4，根据该TA值4可以确定20-40μs内的每段传输的定时提前量；以此类推，可以分别确定40-60μs、60-80μs、80-100μs以及100μs-120μs内的每段传输所使用的的TA值分别为5、6、7、8，由此，可以确定每个时间间隔内的每段传输的定时时间量。
在一些实施例中，定时提前量信息包括初始定时提前TA值、初始调整时间间隔、第一调整增量以及第二调整增量，其中所述第一调整增量指示对初始TA值进行调整的增量，所述第二调整增量指示对初始调整时间间隔进行调整的增量。基站向终端发送该初始TA值、初始调整时间间隔、第一调整增量以及第二调整增量，而终端在接收到该初始TA值、初始调整时间间隔、第一调整增量以及第二调整增量后，终端可以根据初始TA值、初始调整时间间隔、第一调整增量、第二调整增量以及持续传输过程的总时间，确定每段传输的定时提前量。例如，初始TA值为3，初始调整时间间隔为10μs，第一调整增量为1以及第二调整增量为5μs，而总时间假设为120μs，则终端可以确定在0-10μs内进行的每段传输的TA值为3，根据该TA值3可以确定0-10μs内的每段传输的定时提前量；10-25μs内进行的每段传输的TA值为4，根据该TA值4可以确定10-25μs内的每段传输的定时提前量；以此类推，可以分别确定25-45μs、45-70μs、70-100μs以及100μs-120μs内的每段传输所使用的的TA值分别为5、6、7、8，由此，可以确定每个时间间隔内的每段传输的定时时间量。
图8示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。在本实施例中，方法由基站执行，如图8所示，该定时提前量确定方法包括以下步骤：
S801，向终端发送与持续传输过程对应的定时提前量信息以及预配置保护间隔的信息，以使得终端根据所述定时提前量信息以及预配置保护间隔的信息确定持续传输过程中的每段传输的定时提前量。定时提前量信息指示多个定时提前量的信息，例如包括多个定时提前量的值或多个定时提前量的计算参数，预配置保护间隔的信息包括预配置保护间隔的配置周期、起始偏移以及持续时间。
在本实施例中，通过向终端发送定时提前量信息和预配置保护间隔的信息使得终端可以根据该定时提前量信息和预配置保护间隔的信息确定持续传输过程中每段传输的定时提前量，从而避免了信号冲突 的发生。
图9示出了根据本公开实施例的一种定时提前量确定方法的流程示意图。在本实施例中，方法由基站执行，如图9所示，该定时提前量确定方法包括以下步骤：
S901，向终端发送与持续传输过程对应的定时提前量信息，以使得终端根据所述定时提前量信息确定持续传输过程中的每段传输的定时提前量，其中所述定时提前量信息指示多个定时提前量的信息，例如包括多个定时提前量的值或多个定时提前量的计算参数。
该定时提前量信息可以是非地面网络的网络设备根据卫星的变化，例如其运动轨迹、移动速度、方向等信息预先确定的信息。例如，根据卫星的运动轨迹可以知晓卫星在某个持续传输过程中移动情况，由此可以确定该移动情况对于持续传输过程中的传播时延的影响，从而可以确定定时提前量信息，该定时提前量信息可以指示多个定时提前量或多个定时提前量的计算参数，因此能够反映终端在每段传输时使用的定时提前量随着持续传输过程中的不同传播时延的变化。
在本公开的实施例中，通过向终端发送定时提前量信息使得终端可以根据该定时提前量信息确定持续传输过程中每段传输的定时提前量，从而能够适于传播时延的快速变化而对每段传输的定时提前量进行修正，从而能够避免在持续传输过程中由于传播时延的快速变化而造成的上行多用户之间的干扰。
在一些实施例中，定时提前量信息包括与持续传输过程对应的多个定时提前TA值。
在一些实施例中，定时提前量信息包括与持续传输过程对应的多个定时提前TA值以及每个TA值对应的时间间隔。
在一些实施例中，定时提前量信息包括初始定时提前TA值、调整时间间隔以及第一调整增量，其中所述第一调整增量指示对初始TA值进行调整的增量。
在一些实施例中，定时提前量信息包括初始定时提前TA值、初始调整时间间隔、第一调整增量以及第二调整增量，其中所述第一调整增量指示对初始TA值进行调整的增量，所述第二调整增量指示对初始调整时间间隔进行调整的增量。
S902，向终端发送冲突解决机制信息，冲突解决机制信息指示终端在发生本段传输的起始时间早于上一段传输的结束时间的冲突时间段内的传输。
由于持续传输过程中定时提前量出现了变化，这有可能导致信号冲突的情况，例如，假设需要进行6段传输，每段传输所需的传输时间为4μs，根据定时提前量信息确定每段传输的定时提前量为1μs、2μs、4μs、5μs、4μs、7μs，针对每段传输的同步时间点(即基站期望接收到终端发送的上行信号的时间点)分别为5μs、10μs、15μs、20μs、25μs、30μs，则每段传输的起始时间点分别为4μs、8μs、11μs、15μs、21μs、23μs，而每段传输的结束时间分别为8μs、12μs、15μs、19μs、25μs、27μs。其中，第三段传输的起始时间11μs早于第二段传输的结束时间12μs，以及第六段传输的起始时间23μs早于第五段传输的结束时间25μs。也就是说，当第二段传输还没结束时，第三段传输已经开始，以及当第五段传输还没有结束时，第六段传输已经开始。因此，第二段传输和第三段传输出现了信号冲突以及第五段传输和第六段传输发生了信号冲突。为了解决这种冲突，基站可以向终端发送冲突解决机制信息，冲突解决机制信息指示终端在发生本段传输的起始时间早于上一段传输的结束时间的冲突时间段内的传输。例如，该冲突解决机制可以事先规定或者指示终端放弃发生冲突的前一段传输的末尾信号的传输或是放弃发生冲突的后一段传输的初始信号的传输。
根据该冲突解决机制信息，终端可以将引发冲突的后一段传输的初始信号丢弃，即放弃传输该部分初始信号。如上示例，在第三段传输中，放弃前一毫秒(11μs-12μs)的初始信号的传输，在第六段传输中，放弃前两毫秒(23μs-25μs)的初始信号的传输。或者，终端可以将引发冲突的前一段传输的末尾信号丢弃，即放弃传输该部分末尾信号。如上示例，在第二段传输中，放弃后一毫秒(11μs-12μs)的末尾信号的传输，在第五段传输中，放弃后两毫秒(23μs-25μs)的末尾信号的传输。
在本实施例中，通过向终端发生冲突解决机制信息，使得终端在发生信号冲突时，通过放弃发送时间重叠的部分上行信号的传输来解决该冲突。
