Description

一种数据处理方法、装置及存储介质
本申请要求于2019年9月30日提交中国专利局、申请号为201910940643.7、发明名称为“一种数据处理方法、装置及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及无线通信技术领域，具体涉及一种数据处理方法、装置及存储介质。
背景技术
无线通信为用户提供了无限便利，包括语音通信、数据传输等。在长期演进(long term evolution，LTE)和新空口(new radio，NR)的设计中，终端设备(user equipment,UE)接入网络的方式都是基于竞争的随机接入方式。
在NR标准中，终端设备要接入网络，需要进行小区搜索和获取小区系统信息，从而与网络侧(基站/卫星等)取得下行同步。之后，终端设备需要获取小区的系统信息(system information)，并通过随机接入过程(random access procedure)与小区建立连接并取得上行同步。具体地，终端设备通过在网络侧配置的随机接入时机(physical random access occasion，RO)的资源上发送随机接入前导(preamble)以发起随机接入。前导由循环前缀(cyclic prefix,CP)，Zadoff-chu序列，保护时间(guard time,GT)组成。CP的作用是补偿由于往返时延或往返时延差以及多径时延扩展造成的定时误差。一般Zadoff-chu序列和GT的长度不小于CP的长度。因此，当终端设备与网络侧的往返时延或往返时延差越大时，需要的前导长度越长。
目前第三代合作伙伴计划(3rd generation partnership project，3GPP)组织正在研究将第五代移动通信技术(5th generation，5G)NR标准适配到非陆地网络(non-terrestrial networks,NTN)。在NR中，基站与各波束(beam)服务的终端设备基本是在同一个海拔高度上，且各波束中终端设备之间的最大传输时延差(max differential delay)是相同的，同一小区内的不同波束采用相同的随机接入时机配置。
与NR陆地通信场景不同的是，非陆地网络的通信场景中，网络侧与各波束服务的终端设备不在同一海拔高度上，且距离较远，因此非陆地通信的小区直径更大，这就造成同小区内不同地理位置用户的往返时延差较大。例如，地球同步轨道(geostationary earth orbit,GEO)卫星场景的终端设备最大往返时延差可以达到1.6ms，该场景下要求前导最短长度为4.8ms。而NR支持的同小区内终端设备数据传输的最大往返时延差小于0.7ms，前导长度也远远小于非陆地通信中的需求。因此，如果在非陆地通信场景中仍采用NR的随机接入时机的配置来传输较长的前导，那么将会出现前导检测窗重叠等干扰问题，影响网络侧对前导的检测概率。另外，非陆地通信场景中存在同一小区的不同波束中终端设备之间的最大传输时延差不同的情况，使得同一小区的不同波束内所需要的前导长度不同。因此，若非陆地通信场景中仍然采用陆地通信场景中的同小区内的不同波束均采用相同的随 机接入时机的不够灵活的配置方式，可能会产生时域资源浪费的情况。因此，如何实现非陆地场景中不同波束对应的随机接入时机的灵活配置从而避免因前导长度过长而导致的前导检测窗重叠等干扰问题，是一个亟待解决的问题。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，下面结合附图，对本申请的实施例进行描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。本领域普通技术人员可知，随着新应用场景的出现，本发明实施例提供的技术方案对于类似的技术问题，同样适用。
本申请的说明书和权利要求书及上述附图中的术语“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，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。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模块的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或模块，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模块。在本申请中出现的对步骤进行的命名或者编号，并不意味着必须按照命名或者编号所指示的时间/逻辑先后顺序执行方法流程中的步骤，已经命名或者编号的流程步骤可以根据要实现的技术目的变更执行次序，只要能达到相同或者相类似的技术效果即可。本申请中所出现的模块的划分，是一种逻辑上的划分，实际应用中实现时可以有另外的划分方式，例如多个模块可以结合成或集成在另一个系统中，或一些特征可以忽略，或不执行，另外，所显示的或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，模块之间的间接耦合或通信连接可以是电性或其他类似的形式，本申请中均不作限定。并且，作为分离部件说明的模块或子模块可以是也可以不是物理上的分离，可以是也可以不是物理模块，或者可以分布到多个电路模块中，可以根据实际的需要选择其中的部分或全部模块来实现本申请方案的目的。
现有协议中，网络侧通过系统信息信息块类型1(system information block type 1，SIB1)下发物理随机接入信号配置索引(PRACH-configuration index)给UE，UE通过查阅随机接入时机的配置表确定所需要使用的前导格式和发送前导的随机接入时机，然后通过在随机接入时机上发送前导向网络侧发起随机接入。现有协议中随机接入时机在时域上是按照周期配置的，随机接入的帧周期被配置为10ms，20ms，40ms，80ms和160ms。随机接入时机的配置表中还示出了随机接入时机所在的系统帧的帧号、随机接入时机所在的子帧号、随机接入时机的起始符号、随机接入时机所在的子帧内包含的时隙的数目以及随机接入时机所在的时隙内包含的随机接入时机的数量等配置参数。现有协议中，由于随机接入前导的长度较短，通常能够在一个时隙内发送完，因此所配置的随机接入时机之间不存在时隙间隔，仅适用于小区半径小于100km的陆地通信场景。而对于非陆地通信场景中更大的小区，小区内往返时延差更大，所需要发送的前导长度通常都大于一个时隙，因此现有协议中随机接入时机的配置方式并不适用与非陆地通信场景。除此之外，NR中同小区内不同beam内的最大往返时延差是相同的，因此同一个小区的不同beam均采用相同的随机接入时机的配 置，而对于非陆地通信场景而言，同小区内的不同beam内的最大往返时延差存在不相同的情况，因此所需要的前导长度也是不同的，采用相同的随机接入时机配置显然是不够灵活的。
基于上述原因，本申请实施例提供一种数据处理方法，网络设备能够根据目标波束或目标小区内的传输时延差确定随机接入前导所需的第一前导格式，并根据所需的第一前导格式确定目标波束或目标小区内随机接入时机的第一配置信息，使得为目标波束或目标小区配置的随机接入周期包含的随机接入时机之间的间隔大于或等于目标波束或目标小区所需要的随机接入前导的第一前导格式对应的前导长度，从而能够解决非陆地通信场景中前导检测窗重叠等等相互干扰问题。本申请实施例还提供相应的数据处理装置。以下分别进行详细说明。

本申请所涉及的终端设备102可以通过小区搜索与网络设备101建立下行同步。终端设备102在本申请中可以指用户设备(UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备102可以通过空口接入卫星网络并发起呼叫，上网等业务，可以是是支持5G新空口(NR，new radio)的移动设备。典型的，终端设备102可以是移动电话、平板电脑、便携式笔记本电脑、虚拟\混合\增强现实设备、导航设备、地面基站(例如：eNB和gNB)和地面站(ground station，GS)、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，5G网络中的终端设备、未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)或未来的其他通信系统中的终端设备等。

本申请实施例中，网络设备在获取目标信息之后，根据目标信息中的传输时延差确定目标波束或目标小区对应的随机接入前导所需的第一前导格式。
具体地，本申请实施例中，目标波束或目标小区内所需要的随机接入前导的前导长度与传输时延差有关。例如，当目标传输时延差为1ms时，目标波束内随机接入前导的前导长度至少为3ms。传输时延差越大，则所需要的随机接入前导的长度越大。随机接入前导由循环前缀CP，Zadoff-chu序列，保护时间GT组成。随机接入前导存在多种前导格式，不同的 前导格式所对应的随机接入前导中循环前缀CP，Zadoff-chu序列及保护时间GT的长度不同，因此，不同的前导格式对应的随机接入前导的前导长度不相同。根据传输时延差可以确定目标波束或目标小区对应的随机接入前导所需的前导长度，因此，网络设备可以根据传输时延差确定目标波束或目标小区对应的随机接入前导所需的第一前导格式，该第一前导格式所对应的前导长度大于或等于该所需的前导长度。
需要说明的是，本申请实施例中，目标波束或目标小区内所需要的随机接入前导的第一前导格式可以不仅仅是基于传输时延差确定的，在某些情况下，还可能需要结合网络设备覆盖的目标波束或目标小区内终端设备与网络设备间信道的多径时延和网络设备所处的轨道高度等信息进行确定。要保证接入前导的第一前导格式中CP的长度不小于传输时延差与多径时延的和。
可选地，本申请实施例中的目标信息还可以包含网络设备的轨道高度，本申请实施例中，网络设备可以是根据传输时延差和网络设备的轨道高度共同计算出目标波束或目标小区对应的随机接入前导所需的前导长度，然后确定目标波束或目标小区的随机接入前导的第一前导格式。需要说明的是，本申请实施例中的目标信息还可以包含其他的信息，网络设备基于传输时延差、网络设备的轨道高度以及其他的一些信息共同计算目标波束或目标小区对应的随机接入前导所需的前导长度，然后确定目标波束或目标小区的随机接入前导的第一前导格式。
203、网络设备根据第一前导格式从一种或多种配置信息中确定随机接入时机的第一配置信息，第一配置信息用于指示第一前导格式和随机接入周期包含的随机接入时机的第一集合，第一集合包含的随机接入时机之间的间隔大于或等于第一前导格式对应的前导长度。
本申请实施例中，网络设备在确定目标波束或目标小区对应的随机接入前导所需的第一前导格式之后，网络设备根据第一前导格式从一种或多种配置信息中确定随机接入时机的第一配置信息。第一配置信息用于指示第一前导格式和随机接入周期包含的随机接入时机的第一集合，第一集合包含的随机接入时机之间的间隔大于或等于第一前导格式对应的前导长度。本申请实施例中，随机接入周期是指随机接入时机的周期，例如可以是指标准定义的随机接入时机的时间段(time interval)。
本申请实施例中，第一配置信息是一种或多种配置信息中的一个，每一种配置信息都用于指示一种随机接入前导格式和随机接入周期包含的随机接入时机的一个集合。
204、网络设备根据第一配置信息生成对应的第一配置索引。
本申请实施例中，网络设备在根据第一前导格式从一种或多种配置信息中确定随机接入时机的第一配置信息之后，根据第一配置信息生成对应的第一配置索引。
可以理解的是，本申请实施例中，第一配置信息是一个或多种配置信息中的一个，则第一配置信息对应的第一配置索引也可以是一个或多个配置索引中的一个。一个或多个配置索引和一种或多种配置信息存在一一对应的关系。
应理解，本申请实施例中，网络设备和终端设备均预先知道一个或多个配置索引和一种或多种配置信息的一一对应关系。换句话说，终端设备和网络设备均预先存储有该一个 或多个配置索引和一种或多种配置信息之间的一一对应关系。
具体地，本申请实施例中，配置索引和配置信息之间可以存在如表1所示的一一对应关系。
表1 配置索引和配置信息的对应关系
配置索引1 配置信息1
配置索引2 配置信息2
配置索引3 配置信息3
… …
由表1可知配置索引和配置信息之间的对应关系。在实际应用过程中，网络设备在根据第一前导格式从一种或多种配置信息中确定随机接入时机的第一配置信息之后，根据第一配置信息以及配置索引和配置信息之间的一一对应的关系生成对应的第一配置索引，以使得目标波束或目标小区内的终端设备在接收到第一配置索引后，能够根据该一一对应的关系确定第一配置索引对应的第一配置信息，进而能够确定所需用的随机接入前导格式和用于传输随机接入前导的随机接入时机。
本申请实施例中，网络设备能够根据目标波束或目标小区内的传输时延差确定随机接入前导所需的第一前导格式，并根据所需的第一前导格式确定目标波束或目标小区内随机接入时机的第一配置信息，使得为目标波束或目标小区配置的随机接入周期包含的随机接入时机之间的间隔大于或等于目标波束或目标小区所需要的随机接入前导的第一前导格式对应的前导长度，从而能够解决非陆地通信场景中前导检测窗重叠等等相互干扰问题。

Figure PCTCN2020105753-appb-000001
具体地，表2中也示出了配置索引所对应的配置信息所包含的配置参数的取值的一些示例。如表2所示的配置参数的取值，随机接入时机可以是配置于系统帧的子帧0、子帧4和子帧8上；或者随机接入时机可以是配置于系统帧的子帧1、子帧5和子帧9上；或者随机接入时机可以是配置于系统帧的子帧2、和子帧6上；随机接入时机可以是配置于系统帧的子帧0、子帧2、子帧3、子帧5、子帧6或子帧8上。随机接入所在的系统帧可以是满足系统帧号模x等于y,其中，x为3、5、6、7、9-15中的任意一个数值，y为1或0。例如，当x取3，y取1时，代表随机接入时机的帧周期被配置为为3个子帧的长度，即30ms，系统帧的帧号满足除以3余1，例如，系统帧的帧号为4、7、10等等，即随机接入时机位于帧号为4、7、10等等的系统帧上。结合上述的子帧号，即代表随机接入时机被配置在帧号为4、7、10等的系统帧上的子帧0、4和8上，或者子帧1、5和9上，或者子帧2、6和10上，或者子帧0或2或3或5或8上。
本申请实施例中的配置信息还包含随机接入时机的起始时隙号。当子载波间隔为120Khz，一个子帧内包含8个时隙，每个时隙的长度为0.125ms。起始时隙号可以配置为如表2中所示的0～7中的一个或多个取值。当子载波间隔为60Khz，一个子帧内包含4个时隙，每个时隙的长度为0.25ms，起始时隙号可以配置为如表2中所示的0～7中的0、1、2、3四个取值中的一个或多个取值。当子载波间隔为30Khz，一个子帧内包含2个时隙，每个时隙的长度为0.5ms，起始时隙号可以配置为如表2中所示的0～7中的0、1两个取值中的一个或多 个取值。当子载波间隔为15Khz，一个子帧内只包含1个时隙，每个时隙的长度为1ms，起始时隙号可以配置为如表2中所示的0～7中的0这个取值。以子载波间隔为120Khz为例进行说明，当起始时隙号被配置为0时，代表随机接入时机所在子帧上的时隙0为随机接入时机的起始时隙，且该子帧上只有一个随机接入时机；当起始时隙号被配置为0和4时，代表随机接入时机所在子帧上的时隙0和时隙4为随机接入时机的起始时隙，且该子帧上有2个随机接入时机，两个随机接入时机的间隔为0.5ms。
本申请实施例中，网络设备通过对随机接入时机所在的系统帧、随机接入时机所在的子帧以及随机接入时机的起始时隙的配置，实现随机接入周期中随机接入时机之间的间隔大于或等于目标波束或目标小区的随机接入前导所需的第一前导格式对应的前导长度。
例如，假设网络设备确定目标波束或目标小区的随机接入前导所需的第一前导格式对应的前导长度为0.5ms。网络设备根据该第一前导格式确定第一配置信息，该第一配置信息所指示的随机接入周期包含的随机接入时机的之间的间隔等于该第一前导格式对应的前导长度，即0.5ms，则第一配置信息包含的配置参数可以采用如表3中所示的取值。
表3 不同子载波间隔对应的四种配置方式
Figure PCTCN2020105753-appb-000002
如表3中所示，随机接入时机可以是配置于系统帧的子帧0、子帧4和子帧8上；或者随机接入时机可以是配置于系统帧的子帧1、子帧5和子帧9上；或者随机接入时机可以是配置于系统帧的子帧2、和子帧6上；随机接入时机可以是配置于系统帧的子帧0、子帧2、子帧3、子帧5、子帧6或子帧8上。随机接入时机所在的系统帧可以是满足系统帧号模x等于y,其中，x为3、5、6、7、9-15中的任意一个数值，y为1或0，即随机接入时机的帧周期可以是30ms、50ms、60ms、70ms、90ms、100ms、110ms、120ms、130ms、140ms或150ms。当子载波间隔为120Khz，一个子帧内包含8个时隙，每个时隙的长度为0.125ms，随机接入时机的起始时隙号可以配置为0和4，随机接入时机所在的子帧上包含的2个随机接入时机之间的间隔即为0.5ms。当子载波间隔为60Khz，一个子帧内包含4个时隙，每个时隙的长度为0.5ms，起始 时隙号可以配置为0和2，随机接入时机所在的子帧上包含的2个随机接入时机之间的间隔即为0.5ms。当子载波间隔为30Khz，一个子帧内包含2个时隙，每个时隙的长度为0.25ms，起始时隙号可以配置为0和1，随机接入时机所在的子帧上包含的2个随机接入时机之间的间隔即为0.5ms。当子载波间隔为15Khz，一个子帧内只包含1个时隙，每个时隙的长度为1ms，可以通过配置随机接入时机所在子帧或时隙内的随机接入时机的数量为2使得随机接入时机所在的子帧上包含的2个随机接入时机之间的间隔即为0.5ms。
需要说明的是，表3中的配置参数的取值只是举例，配置参数也可以是采用其他的取值，本申请实施例对此不做限定。

具体地，本申请实施例中，第一配置索引为一种或多种配置索引种的一种。配置索引可以是物理随机接入信道PRACH配置索引(PRACH configuration index)。配置索引的大小可以是与一种或多种配置信息对应。例如，多种配置信息为小于或者等于2 n个配置信息，则配置索引的大小可以是n比特，本申请实施例对此不做限定。以n＝8为例，当配置索引的大小是8个比特时，可以对应于多种(例如，小于或等于256)配置信息。该n个比特中的m个比特用于指示随机接入时机的起始时隙号，m的大小可以是与起始时隙号的个数对应。例如，当子载波间隔为120Khz，一个子帧内包含8个时隙，此时对应8个时隙号，0～7，因此需要3个比特指示起始时隙号，即m＝3。该n个比特种的(n-m)个比特则用于指示目标参数集合对应的多种(例如，小于或等于2 n-m)取值。
可选地，本申请实施例中，第一配置索引包含第一索引和第二索引，第一索引用于指示目标参数集合，第二索引用于指示随机接入时机的起始时隙号。
具体地，本申请实施例中，第一配置索引为一种或多种配置索引种的一种。配置索引可以包含第一索引和第二索引，其中，第一索引用于指示目标参数集合，而第二索引用于指示随机接入时机的起始时隙号。本申请实施例中，网络设备可以使用表示循环移位信令的高层参数的4个比特来表示第二索引。本申请实施例中，网络设备也可以通过在高层信令(例如，SIB1)中增加比特位来指示该第二索引并进行发送。本申请实施例对此不做限定。

图4为本申请实施例提供的数据处理方法的另一个实施例示意图。
参阅图4，本申请实施例提供的数据处理方法的另一个实施例，包括：
401、网络设备获取目标波束或目标小区内的目标信息，目标信息包括传输时延差和参考多径时延，该传输时延差为第一位置和第二位置分别对应的通信往返时延的差值，第一位置为目标波束或目标小区覆盖区域内的参考点所对应的位置，第二位置为目标波束或目标小区覆盖区域内距离网络设备最远的位置。
本申请实施例中与传输时延差有关的内容可以参阅图3中的步骤301进行理解，此处不再赘述。
本申请实施例中，目标信息中还包括参考多径时延。
目标波束或目标小区内可以包含不具备定位功能的终端设备，也可以包含具备定位功能的终端设备。由于具备定位功能的终端设备可以通过定位功能确定自身的位置信息，同时通过获取卫星等基站位置可以计算出其发送信号时所需要的定时提前量，从而减少前导中的CP需要补偿的由于往返时延或者往返时延差造成的定时误差。即具备定位功能的终端设备所需要的前导格式对应的前导长度更短。在理想情况下，具备定位功能的终端设备所需要的随机接入前导的前导格式中可以不用考虑目标波束或目标小区内的传输时延差。然而，具备定位功能的终端设备还是需要考虑多径效应所带来的时延扩展对接收端的解码信号的影响。需要通过补偿CP来补偿多径时延带来的影响。在通信过程中，发射端的网络设备发射出来的信号可以经过直达路径到达接收端的终端设备，也可以因反射和绕射经由非直达路径到达接收端的终端设备。信号反射的数量决定于信号入射角、载波频率、入射波的极化等因素。由于直达路径和各种非直达反射路径的长度不同，因此经过不同路径的信号分量到达接收端的终端设备的时间不同，这就产生了多径时延。多径时延可以是指经过不同路径的信号分量到达接收端的最短时间和最长之间的差值。
本申请实施例中的参考多径时延，可以是指目标波束或目标小区覆盖范围内的不同位置所对应的多径时延中最大的多径时延。在实际应用的过程中，参考多径时延可以不需要实时测量，可以直接采用最差的多径时延的经验值。例如，在陆地通信过程中的前导CP的长度都是固定的，该固定的CP长度是通过对信道进行测量所得到的城市里的通信信道的多径时延的最大值来确定的。
可选地，本申请实施例中，网络设备的轨道高度可能会导致一定的路径损耗，路径损耗的大小也前导长度具有一定的影响，路径损耗越大，需要的前导长度越长。因此，本申请实施例中的目标信息还可以包含网络设备的轨道高度。
402、网络设备根据传输时延差确定目标波束或目标小区对应的随机接入前导所需的第一前导格式。
本申请实施例可以参阅图3中的步骤302进行理解，此处不再赘述。

本申请实施例可以参阅图3中的步骤303进行理解，此处不再赘述。
需要说明的是，本申请实施例中存在多种配置信息，第一配置信息为多种配置信息中的一种。
404、网络设备根据第一配置信息生成对应的第一配置索引。
本申请实施例可以参阅图2中的步骤204进行理解，此处不再赘述。
405、网络设备根据参考多径时延确定目标波束或目标小区对应的随机接入前导所需的第二前导格式。
本申请实施例中，网络设备在获取目标信息之后，根据目标信息中的参考多径时延确定目标波束或目标小区对应的随机接入前导所需的第二前导格式，需要保证第二前导格式中的CP长度不小于参考多径时延的长度。
需要说明的是，本申请实施例中，目标波束或目标小区内所需要的随机接入前导的第二前导格式可以不仅仅是基于参考多径时延得到的，在某些情况下，还可能需要结合网络设备所处的轨道高度等信息进行确定。
可选地，本申请实施例中的目标信息还可以包含网络设备的轨道高度，本申请实施例中，网络设备可以是根据参考多径时延和网络设备的轨道高度共同计算出目标波束或目标小区对应的随机接入前导所需的第二前导长度。
406、网络设备根据第二前导格式从多种配置信息中确定随机接入时机的第二配置信息，第二配置信息用于指示第二前导格式和随机接入周期包含的随机接入时机的第二集合，第二集合包含的随机接入时机之间的间隔大于或等于第二前导格式对应的前导长度。
本申请实施例中，网络设备在确定目标波束或目标小区对应的随机接入前导所需的第二前导格式之后，网络设备根据第二前导格式从多种配置信息中确定随机接入时机的第二配置信息。第二配置信息用于指示第二前导格式和随机接入周期包含的随机接入时机的第二集合，第二集合包含的随机接入时机之间的间隔大于或等于第二前导格式对应的前导长度。本申请实施例中，第二配置信息是多种配置信息中的一个，每一种配置信息都用于指示一种随机接入前导格式和随机接入周期包含的随机接入时机的一个集合。
需要说明的是，本申请实施例中的第二配置信息和第一配置信息是多种配置信息中不同的两种配置信息。
407、网络设备根据第二配置信息生成对应的第二配置索引。
本申请实施例中，网络设备在根据第二前导格式从多种配置信息中确定随机接入时机的第二配置信息之后，根据第二配置信息生成对应的第二配置索引。
可以理解的是，本申请实施例中，第一配置信息和第二配置信息是多种配置信息中不同的两种配置信息，则第二配置信息对应的第二配置索引和第一配置索引也是多个配置索引中不同的两个配置索引。
需要说明的是，本申请实施例对步骤402-步骤404，以及步骤405-步骤407的先后顺序不做具体的限定。
408、网络设备向目标波束或目标小区发送下行信息，该下行信息包括第一配置索引和第二配置索引。
本申请实施例中，网络设备在分别生成第一配置索引和第二配置索引之后，向目标波束或目标小区发送下行信息，该下行信息包括第一配置索引和第二配置索引。
本申请实施例中关于配置索引的相关内容也可以参阅图3中的步骤305进行理解，此处不再赘述。
409、终端设备接收下行信息，并判断是否具备定位功能。
本申请实施例中，终端设备在接收到包含第一配置索引和第二配置索引的下行信息之后，首先判断是否具备定位功能。
410、若不具备，则终端设备根据第一配置索引确定第一配置信息，且根据第一配置信息确定随机接入前导格式和用于传输随机接入前导的随机接入时机。
本申请实施例中，若终端设备判断自身不具备定位功能，则终端设备根据第一配置索引确定第一配置信息，然后根据第一配置信息所指示的第一前导格式和第一集合，确定随机前导格式为第一前导格式，并从第一集合中确定用于传输随机接入前导的随机接入时机。
411、若具备，则终端设备根据第二配置索引确定第二配置信息，且根据第二配置信息确定随机接入前导格式和用于传输随机接入前导的随机接入时机。
本申请实施例中，若终端设备判断自身具备定位功能，则终端设备根据第二配置索引确定第二配置信息，然后根据第二配置信息所指示的第二前导格式和第二集合，确定随机前导格式为第二前导格式，并从第二集合中确定用于传输随机接入前导的随机接入时机。
本申请实施例中，网络设备分别根据目标波束或目标小区内的传输时延差和参考多径信号确定随机接入前导所需的第一前导格式和第二前导格式，并根据所需的第一前导格式和第二前导格式确定目标波束或目标小区内随机接入时机的两种配置信息，该两种配置信息所指示的随机接入时机之间的间隔都大于或等于对应的前导格式所对应的前导长度，该两种配置信息分别用于目标波束或目标小区内具备定位功能和不具备定位功能的终端设备确定随机接入前导格式和用于传输随机接入前导的随机接入时机，不但能够避免非陆地通信场景中前导检测窗重叠等等相互干扰问题，还能够针对不同的终端设备进行随机接入时机的配置，能够节约随机接入前导所占用的时频资源。
