背景技术
第五代(the fifth generation，5G)移动通信***致力于支持更高的***性能，支持多种业务类型、不同部署场景和更宽的频谱范围。其中，多种业务类型包括增强移动宽带(enhanced mobile broadband,eMBB)、海量机器类型通信(massive machine type communication,mMTC)、超可靠低延迟通信(ultra-reliable and low-latency communications,URLLC)、多媒体广播多播业务(multimedia broadcast multicast service,MBMS)和定位业务等。
URLLC业务对数据传输的时延和可靠性要求都比较高，在一些场景中，利用普通循环前缀的时隙传输URLLC业务无法满足时延要求，因此，需要利用扩展循环前缀的时隙传输URLLC业务。但是由于URLLC业务的上行数据和下行数据是同时存在的，利用扩展循环前缀的时隙传输URLLC业务不能保证URLLC业务的上行数据和下行数据同时传输，严重影响了URLLC业务中上行数据和下行数据的传输，影响了URLLC业务的正常运行，降低了通信效率。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请实施例的技术方案可以应用于各种通信***，例如：全球移动通信(global system for mobile communications，GSM)***、码分多址(code division multiple access，CDMA)***、宽带码分多址(wideband code division multiple access，WCDMA)***、通用分组无线业务(general packet radio service，GPRS)、长期演进(long term evolution，LTE)***、LTE频分双工(frequency division duplex，FDD)***、LTE时分双工(time division duplex，TDD)、通用移动通信***(universal mobile telecommunication system，UMTS)、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信***、未来的第五代(5th generation，5G)***或新无线(new radio，NR)等。

本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通信(global system for mobile communications，GSM)***或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)***中的基站(NodeB，NB)，还可以是LTE***中的演进型基站(evoled NodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作***层，以及运行在操作***层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作***可以是任意一种或多种通过进程(process)实现业务处理的计算机操作***，例如，Linux操作***、Unix操作***、Android操作***、iOS操作***或windows操作***等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且，本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
另外，本申请的各个方面或特征可以实现成方法、装置或使用标准编程和/或工程技 术的制品。本申请中使用的术语“制品”涵盖可从任何计算机可读器件、载体或介质访问的计算机程序。例如，计算机可读介质可以包括，但不限于:磁存储器件(例如，硬盘、软盘或磁带等)，光盘(例如，压缩盘(compact disc，CD)、数字通用盘(digital versatile disc，DVD)等)，智能卡和闪存器件(例如，可擦写可编程只读存储器(erasable programmable read-only memory，EPROM)、卡、棒或钥匙驱动器等)。另外，本文描述的各种存储介质可代表用于存储信息的一个或多个设备和/或其它机器可读介质。术语“机器可读介质”可包括但不限于，无线信道和能够存储、包含和/或承载指令和/或数据的各种其它介质。
第五代(the fifth generation，5G)移动通信***致力于支持更高的***性能，支持多种业务类型、不同部署场景和更宽的频谱范围。其中，多种业务类型包括增强移动宽带(enhanced mobile broadband,eMBB)、海量机器类型通信(massive machine type communication,mMTC)、超可靠低延迟通信(ultra-reliable and low-latency communications,URLLC)、多媒体广播多播业务(multimedia broadcast multicast service,MBMS)和定位业务等。
典型的URLLC业务对数据传输的时延要求较高，URLLC业务主要包括：工业制造或生产流程中的无线控制、无人驾驶汽车和无人驾驶飞机的运动控制以及远程修理、远程手术等触觉交互类应用。这些业务的主要特点是要求超高可靠性、低延时，传输数据量较少以及具有突发性。
典型的mMTC业务有：智能电网配电自动化、智慧城市等。这种业务的主要特点是联网设备数量巨大、传输数据量较小、数据对传输时延不敏感。这些mMTC通信设备需要满足低成本和非常长的待机时间的需求。
典型的eMBB业务对于数传输时延不敏感，并且数据传输量大。典型的eMBB业务主要包括：超高清视频、增强现实(augmented reality，AR)、虚拟现实(virtual reality，VR)等，这些业务的主要特点是传输数据量大、传输速率很高。
目前，NR***支持各种时间单元的调度，时间单元的长度可以为一个或多个时域符号。符号可以为正交频分复用符号(orthogonal frequency division multiplexing，OFDM)。NR***的时域资源是由时隙(slot)组成的。对于普通循环前缀(normal cyclic prefix，NCP)的时隙格式，一个slot包括14个符号。对于扩展循环前缀(extended cyclic prefix,ECP)的时隙格式，一个slot包括12个符号。NR***支持多种子载波间隔。不同的子载波间隔下时隙slot对应的时间长度不同。例如,当子载波间隔为15kHz，一个slot对应的时间长度为1ms，当子载波间隔30kHz，一个slot对应的时间长度为0.5ms，当子载波间隔60kHz，一个slot对应的时间长度为0.25ms，当子载波间隔120kHz，一个slot对应的时间长度为0.125ms。由于一个时隙的符号数一直都是14或者12个符号，因此可以理解的是，一个符号对应的时间长度也随着子载波间隔的变化而变化。
网络设备会使用物理层信令或高层信令通知一个或多个时隙中的上行符号(Uplink Symbol，U)、下行符号(Downlink Symbol，D)和灵活符号(Flexible Symbol，F)在一个时隙内的分布。其中，上行符号是用于传输上行数据和/或上行控制信息，下行符号是用于传输下行数据和/或下行控制信息，灵活符号可能用于传输上行数据和/或上行控制信息，或下行数据和/或下行控制信息，灵活符号用于上行传输和下行传输取决于网络设备的下行控制信息(downlink control information，DCI)。当网络设备通过DCI指示某一 个时隙资源为上行信道，且该资源包括灵活符号，此时灵活符号用于传输上行数据和/或上行控制信息。当网络设备通过下行控制信息DCI指示某一个时域资源为下行信道，且该时域资源包括灵活符号，此时灵活符号用于传输下行数据和/或下行控制信息。但是，灵活符号一般不可以同时承载上行和下行的数据和/或控制信息。
目前，网络设备是通过时隙格式指示(slot format indication，SFI)向终端设备指示一个时隙内的U、D和F的位置的，例如，表1所示的为对于普通循环前缀的时隙格式的时隙格式指示表格。

对于普通循环前缀时隙，由于不同子载波间隔对应的时隙长度是不同的，可以利用不同的子载波之间的符号对应关系确定其中一个子载波间隔的时隙包括的符号为上行符号、下行符号或者为灵活符号。例如，子载波间隔为15kHz的一个时隙相当于子载波间隔30kHz对应的两个时隙，子载波间隔为15kHz的一个符号的时间长度和子载波间隔30kHz对应的两个符号的时间长度相同，则子载波间隔为15kHz的一个U可以映射(对应)为子载波间隔30kHz对应的两个U，子载波间隔为15kHz的一个D可以映射为子载波间隔30kHz对 应的两个D，子载波间隔为15kHz的一个F可以映射为子载波间隔30kHz对应的两个F。类似的，对于子载波间隔为15kHz和子载波间隔为60kHz的对应的时隙格式，子载波间隔为15kHz的一个符号的时间长度和子载波间隔60kHz对应的4个符号的时间长度相同，则子载波间隔为15kHz的一个U可以映射为子载波间隔60kHz对应的4个U，子载波间隔为15kHz的一个D可以映射为子载波间隔60kHz对应的4个D，子载波间隔为15kHz的一个F可以映射为子载波间隔60kHz对应的4个F。类似的，对于子载波间隔为30kHz和子载波间隔为60kHz的对应的时隙格式、子载波间隔为30kHz和子载波间隔为120kHz的对应的时隙格式等，也可以根据上述的映射关系，确定对应的子载波间隔的时隙格式。
另外，对于扩展循环前缀的时隙，由于对于相同的子载波间隔而言，ECP对应的时隙和NCP对应的时隙的时间长度是相同的，并且，时隙边界是对齐的。根据现有的协议定义的。ECP对应的时隙格式是根据NCP对应的时隙格式来确定的。具体的实现方法为：
如果一个ECP符号(ECP symbol)与NCP symbol的D或者U重叠(即使同时也与F重叠)，那么ECP symbol的方向与NCP symbol的方向相同；
例如，一个ECP符号与NCP的DD或DF或FD重叠，那么这个ECP符号对应为D。如果一个ECP符号与NCP的UU或UF或FU重叠，那么这个ECP符号对应为U。
如果一个ECP symbol只与NCP symbol的F重叠，那么ECP symbol为F。
例如，一个ECP符号与NCP的FF重叠，那么这个ECP符号对应为F。
如果一个ECP symbol同时与NCP symbol的D和U重叠，那么ECP symbol为F。
例如，一个ECP符号与NCP的DU重叠，那么这个ECP符号对应为F。
根据以上的实现方式，则可以确定出ECP对应时隙格式，表2所示的为子载波间隔为60kHz时对应的ECP时隙格式表格。

可以发现：表格2中的时隙格式索引3指示的时隙格式3与时隙格式索引1指示的时隙格式重复，表格2中的时隙格式索引28、31、34-36和45-47这几个时隙格式中，由于D→U中间没有F。则不可用。因为标准中定义，DU之间一定有F的存在，因为终端设备需要从下行接收到上行发送的转换时间，所以这些格式由于没有预留转换时间则不可用。但是，U→D中间是可以没有F的。
在无线通信***中，在上行数据传输(终端设备发向网络设备)或下行数据传输(网络设备发向终端设备)时，需要传输参考信号。这是因为接收端在进行数据译码之前，需要使用参考信号对于信道进行信道估计，进而使用信道估计的结果将空间信道对于数据的影响去掉，从而进行译码。例如，以同步信号块(Synchronization Sigal block,SSB)或者物理广播信道块(physical Broadcast channel block,PBCH block)为例，网络设备会先向终端设备发送SSB，终端设备根据SSB，识别小区以及和小区进行同步等。终端设备成功接收同步信号块是其接入小区的前提。由于同步信号块是网络设备发送终端设备的下行信号，因此，如果某一个时隙中存在SSB的传输，则SSB所占的符号应该为D。目前存在以下几种SSB的传输情况，其中，每次SSB的传输占据4个符号。
Case A：用15kHz子载波间隔对应的时隙格式传输SSB，SS/PBCH block的起始符号对应的索引为{2，8}+14*n。如果载波的频域小于或等于3GHz，n＝0,1；如果载波的频域小于或等于6GHz，n＝0,1,2,3。符号的索引可以理解为符号的编号，例如，对于NCP的时隙格式，14个符号的编号分别为0至13，对于ECP的时隙格式，12个符号的编号分别为0至11。
Case B：用30kHz子载波间隔对应的时隙格式传输SSB，SS/PBCH block的起始符号对应的索引为{4，8，16,20}+28*n，如果载波的频域小于或等于3GHz，n＝0；如果载波的频域小于或等于6GHz，n＝0,1。
Case C：用于30kHz子载波间隔对应的时隙格式传输SSB，SS/PBCH block起始符号对应的索引为{2，8}+14*n。对于对称频谱(FDD***)，如果载波的频域小于或等于3GHz，n＝0,1；如果载波的频域大于3GHz且小于或等于6GHz，n＝0,1,2,3。对于非对称频谱(TDD***)，如果GHz小于或等于2.4GHz，n＝0,1；如果GHz大于2.4G小于或等于6GHz，n＝0,1,2,3。
根据60kHz子载波间隔对应的NCP和30kHz子载波间隔对应的NCP时隙格式之间的映射关系以及60kHz子载波间隔对应的NCP和ECP时隙格式之间的映射关系，可以确定出Case C对应的SSB映射到60kHz子载波间隔对应的NCP和ECP上的符号位置。如图1所示的，图1所示为Case C对应的SSB映射到60kHz子载波间隔对应的NCP和ECP 上的符号位置。
从NR***中定义可知，携带相同信息的信号由于传播路径不同，从而导致到达接收侧的时延差大于循环前缀(cyclic prefix，CP)对应的时间长度时，就会有造成不同符号的干扰，这些符号间干扰会大幅度降低信号接收的成功率。所以在NR***中是要避免这种情况的出现。目前，在研究中发现在工厂环境中最大时延差(约2.4us-2.6us)较大。表3所示的为NR***中定义不同子载波对应的CP长度，从表3中可以看出，工厂环境中最大时延差已经大于30Khz/60Khz子载波间隔对应的NCP时隙格式的CP长度，也就是说：现有***中利用30Khz/60Khz子载波间隔NCP时隙格式传输的方式不可用。与此对应的，只能使用15Khz子载波间隔NCP，或者60Khz子载波间隔ECP时隙格式进行数据的传输。由于15Khz子载波间隔NCP的时隙格式中每个符号的所占用的时域长度太长，进而每次传输所占用的时域长度太长，导致15Khz子载波间隔NCP不适用于URLLC这种时延敏感的业务。这样唯一的选择就是使用60Khz子载波间隔ECP时隙格式进行数据的传输。

对于利用使用60Khz子载波间隔ECP时隙格式进行数据的传输时，首先需要保证SSB的正常传输。从图1中可以看出，对于使用60Khz子载波间隔ECP时隙格式进行SSB传输，存在两种不同的传输格式(传输图案)，其中，第一种传输格式需要保证第一个时隙内符号3至符号10均为下行符号，第二种传输格式需要保证第二个时隙内符号1至符号8均为下行符号。结合表2中所示的60Khz子载波间隔ECP的时隙格式，那么表格2中可以使用时隙格式包括：
第一种传输格式对应的时隙格式包括：DDD”DDDDDDDD”F，对应格式索引4
第二种传输格式对应的时隙格式包括：
DDDDDDDDDDDDD，对应格式索引0/3，
DDDDDDDDDDDDF，对应格式索引4，
DDDDDDDDDDDFF，对应格式索引5，
DDDDDDDDDDFFF，对应格式索引6，
DDDDDDDDDDDDU，对应格式索引28—有问题不可用，
DDDDDDDDDDDFU，对应格式索引29，
DDDDDDDDDDFFU，对应格式索引30，
DDDDDDDDDDDUU，对应格式索引31—有问题不可用，
DDDDDDDDDDFUU，对应格式索引32，
可以看出：表格2中现有可用的时隙格式中基本上都是D，也就是现有时隙格式在满 足SSB传输的基础上，只适用于传输下行数据。但在工厂场景中，上行和下行URLLC业务是同时存在的，也就是说现有时隙格式不适用于传输上行数据。严重影响了URLLC业务中上行数据的传输，影响了URLLC业务的正常运行，降低了通信效率。
有鉴于此，本申请体用了一种时隙格式指示的方法和通信装置，可以使得时隙格式在支持下行信号传输的同时也可以上行数据的传输，保证了URLLC业务中上行数据的传输，保障了URLLC业务的正常运行。

应理解，下文的描述中，以终端设备和网络设备作为各个实施例的执行方法的执行主体为例，对各个实施例的方法进行说明。作为示例而非限定，执行方法的执行主体也可以是应用于终端设备和网络设备的芯片。
如图3所示，图3中示出的方法200可以包括步骤S210至步骤S220。下面结合图3详细说明方法200中的各个步骤。该方法200包括：
S210,网络设备根据扩展循环前缀的时隙格式，确定时隙格式索引。该扩展循环前缀的时隙格式包括下行符号D、至少一个上行符号U和/或至少一个灵活符号F。该时隙格式索引用于指示时隙格式表中的一行，该时隙格式表中的一行用于指示至少12个符号分别对应的符号属性，该符号属性包括上行符号U、下行符号D或灵活符号F的位置。可选的，该时隙格式索引的取值大于或等于56且小于或等于254。

S230，终端设备根据该时隙格式索引，确定扩展循环前缀的时隙格式，该扩展循环前缀的时隙格式包括下行符号D、至少一个上行符号U和/或至少一个灵活符号F。
具体而言，在S210中，在网络设备和终端设备之间进行数据的传输时，网络设备可以将用于数据传输的时隙格式索引通知给终端设备。具体的，由上述可知，为了满足 URLLC业务的传输时延要求，需要利用扩展循环前缀时隙格式进行数据的上行和下行传输。因此，网络设备根据扩展循环前缀的时隙格式，确定时隙格式索引。该扩展循环前缀的时隙格式对应的子载波间隔可以为30KHz子载波间隔、60KHz子载波间隔、120K子载波间隔以及240KHz子载波间隔中的任意一种。并且，该扩展循环前缀的时隙格式包括下行符号D、至少一个上行符号U和/或至少一个灵活符号F。也就是说，该扩展循环前缀的时隙格式需要满足适用上行传输和下行传输，并且需要满足URLLC业务的传输时延。例如，该扩展循环前缀的时隙格式可以60Khz子载波间隔ECP时隙格式。并且，该扩展循环前缀的时隙格式还需要满足可以传输SSB的要求，例如，对于利用上述的60Khz子载波间隔ECP时隙格式传输SSB时，需要满足的上述的两种传输格式，即需要满足SSB所占的符号位置为下行符号。
该时隙格式索引用于指示时隙格式表中的一行。时隙格式表的形式可以和上述的表1或表2的形式类似。该时隙格式索引相当于表1或者表2中第一列中格式(format)。该时隙格式索引的值相当于表1或者表2中第一列中格式(format)的取值。可选的，在本申请实施例中，该时隙格式索引的取值大于或等于56且小于或等于254。即可以利用时隙格式索引的保留值指示时隙格式。应理解，在本申请实例中，该时隙格式索引的取值也可以小于56。或者，该时隙格式索引的取值也可以大于254。该时隙格式表指示的时隙格式可以为扩展循环前缀时隙，也可以是普通循环前缀时隙。
该时隙格式表用于指示一个时隙包括的12或者14符号的符号属性，该符号属性可以理解为一个符号为上行符号U、下行符号D或灵活符号F的属性。时隙格式表可以是预配置的或者预定义的。时隙格式表指示的时隙格式可以为普通循环前缀的时隙格式(14符号)或者扩展循环前缀时隙格式(14个符号)。时隙格式表指示的时隙格式对应的子载波间隔也可为15KHz子载波间隔、30KHz子载波间隔、60KHz子载波间隔、120K子载波间隔以及240KHz子载波间隔等子载波间隔中的任意一种。可选的，该时隙格式索引指示的时隙格式对应的子载波间隔小于或等于该扩展循环前缀的时隙格式对应的子载波间隔。
在S220中，网络设备向终端设备发送该时隙格式索引。相应的，终端设备接收该时隙格式索引。例如，网络设备可以通过高层信令或者物理层信令向终端设备发送该时隙格式索引。
在S230中，终端设备根据该时隙格式索引，可以确定该时隙格式索引指示的时隙表格中的某一个行的12个或者14个符号的符号属性，根据该12个或者14个符号的符号属性，可以确定该扩展循环前缀的时隙格式。其中，该扩展循环时隙格式适用上行传输和下行传输，并且需要满足URLLC业务的传输时延要求。并且，该扩展循环前缀的时隙格式包括下行符号D、至少一个上行符号U和/或至少一个灵活符号F。
本申请提供的时隙格式指示的方法，网络设备通过向终端设备发送时隙格式索引，该时隙格式索引用于终端设备确定扩展循环前缀的时隙格式，并且，该扩展循环前缀的时隙格式包括下行符号D、至少一个上行符号U和/或至少一个灵活符号F。该扩展循环前缀的时隙格式可以满足URLLC业务的上行传输和下行传输以及传输时延要求，并且可以保证SSB的正常传输，从而保证了URLLC业务的正常传输。
在上述的S220中，网络设备向终端设备发送该时隙格式索引。具体的，网络设备会 根据该时隙格式表格中的最大时隙格式索引，确定第一比特数。该时隙格式表格中的最大时隙格式索引可以理解为该时隙格式表格中的时隙格式索引的最大取值。网络设备会向终端设备发送该第一比特数对应的第一比特状态值，该第一比特状态值用于指示该时隙格式索引。例如，该时隙格式表格中的时隙格式索引的最大取值为128，则第一比特数为7比特，每个比特位的比特状态可以为0或1，则第一比特数对应的比特状态值就有128种。第一比特状态值为该128种比特状态值的一种，并且，该第一比特状态值用于指示某一个时隙格式索引的取值。终端设备接收到该第一比特状态值后，便可以根据该第一比特状态值，确定第一比特状态值指示的时隙格式索引。可选的，该第一比特数可以由公式(1)计算得出。

在本申请实例中，作为一种可能的实现方式，网络设备向终端设备发送的时隙格式索引包括用于指示以下两种符号属性的时隙格式索引中的至少一种：
第一种符号属性为：Y 0Y 1Y 2Z 0DDDDDDDD Y 3Y 4，其中，D表示下行符号，Y 0至Y 3均表示灵活符号、上行符号以及下行符号中的任意一个，Z 0表示灵活符号或者下行符号,Y 4表示灵活符号或者上行符号。
第二种符号属性为：X 0X 1DDDDDDDDX 2X 3X 4X 5，其中，D表示下行符号，X 0和X 1均表示灵活符号或者上行符号，X 2表示灵活符号或者下行符号，X 3表示灵活符号或者上行符号，X 4和X 5均表示灵活符号、上行符号以及下行符号中的任意一个。
具体而言，对于网络设备向终端设备发送的时隙格式索引对应的时隙表格为子载波间隔为60KHz下的普通循环前缀格式表格，并且，终端设备最终进行上下行数据传输利用的扩展循环前缀的时隙格式为子载波间隔为60KHz下的扩展循环前缀格式的情况下。由于该扩展循环前缀的时隙格式还需要保证SSB的传输，该扩展循环前缀的时隙格式需要满足图2所示的时隙格式，即60KHz下的扩展循环前缀格式需要满足：第一种传输格式(或者称为第一种符号属性)需要保证某一个时隙内符号3至符号10均为下行符号，相当于保证了图2中60KHz下的扩展循环前缀格式第一个时隙中的时隙格式。第二种传输格式(或者称为第二种符号属性)需要保证某一个时隙内符号1至符号8均为下行符号，相当于保证了图2中60KHz下的扩展循环前缀格式第二个时隙中的时隙格式。由于该时隙格式索引对应的时隙表格为子载波间隔为60KHz下的普通循环前缀格式表格，终端设备可以根据上述的扩展循环前缀的时隙格式和普通循环前缀的时隙格式之间的映射关系，根据60KHz下的普通循环前缀格式，确定出60KHz下的扩展循环前缀格式。并且，确定出的60KHz下的扩展循环前缀格式需要满足：第一种传输格式需要保证符号3至符号10均为下行符号，第二种传输格式需要保证符号1至符号8均为下行符号。而且，其他符号位置上需要包括上行符号U和/或灵活符号F。
因此，对于该时隙格式索引对应的时隙表格为子载波间隔为60KHz下的普通循环前缀格式，该时隙格式索引包括用于指示子载波间隔为60KHz下的普通循环前缀格式的两种符号属性中的至少一种：
第一种符号属性为：Y 0Y 1Y 2Z 0DDDDDDDD Y 3Y 4，其中，D表示下行符号，Y 0至 Y 3均表示灵活符号、上行符号以及下行符号中的任意一个，Z 0表示灵活符号或者下行符号,Y 4表示灵活符号或者上行符号。
第二种符号属性为：X 0X 1DDDDDDDDX 2X 3X 4X 5，其中，D表示下行符号，X 0和X 1均表示灵活符号或者上行符号，X 2表示灵活符号或者下行符号，X 3表示灵活符号或者上行符号，X 4和X 5均表示灵活符号、上行符号以及下行符号中的任意一个。
第一种符号属性和第二中符号属性对应的均为子载波间隔为60KHz下的普通循环前缀时隙格式。
具体而言，对于第一种符号属性，作为一种可能的实现方式，该时隙格式索引的可能的取值和每个可能的取值指示的14个符号的符号属性可以为表4所示的。
表4

表4所示的时隙表格中，D表示下行符号，Z 0表示灵活符号或者下行符号,Y 3表示灵活符号、上行符号以及下行符号中的任意一个，Y 4表示灵活符号或者上行符号。但是，在Y 3表示的为D时，在Y 4表示的不能为U。
应该理解的是，表4只是示例性的，不应该对该时隙格式索引的取值以及与该时隙格式索引对应的14个符号的符号属性产生限制。例如，表4中时隙格式索引的取值还可以为其他取值，例如71至85等。
终端设备接收到表4所示的任意一个时隙格式索引时，便可以根据该时隙格式索引确定60KHz下的普通循环前缀格式，在确定出了某一个60KHz下的普通循环前缀格式后，根据60KHz下的普通循环前缀格式和扩展循环前缀的时隙格式之间的映射关系，确定出60KHz下的扩展循环前缀的时隙格式。该60KHz下的扩展循环前缀的时隙格式包括下行 符号D、至少一个上行符号U和至少一个灵活符号F，从而保证了URLLC上行业务和下行业务的传输。并且，该60KHz下的扩展循环前缀的时隙格式还可以满足第一种传输格式要求，即可以保证SSB的传输，从而保障了通信的质量。
对于第二种符号属性为：X 0X 1DDDDDDDDX 2X 3X 4X 5，其中，D表示下行符号，X 0和X 1均表示灵活符号或者上行符号，X 2表示灵活符号或者下行符号，X 3表示灵活符号或者上行符号，X 4和X 5均表示灵活符号、上行符号以及下行符号中的任意一个。作为一种可能的实现方式，对于第二种符号属性，该时隙格式索引的可能的取值和每个可能的取值指示的14个符号的符号属性可以为表5所示的。
表5
Figure PCTCN2020089339-appb-000010
表5所示的时隙表格中，X 0和X 1均表示灵活符号或者上行符号，X 2表示灵活符号或者下行符号。
应该理解的是，表5只是示例性的，不应该对该时隙格式索引的取值以及与该时隙格式索引对应的14个符号的符号属性产生限制。例如，表4中时隙格式索引的取值还可以为其他取值等。
终端设备接收到表5所示的任意一个时隙格式索引时，便可以根据该时隙格式索引确定对应的60KHz下的普通循环前缀格式，在确定出了某一个60KHz下的普通循环前缀格式后，根据60KHz下的普通循环前缀格式和扩展循环前缀的时隙格式映射关系或者对应关系，确定出60KHz下的扩展循环前缀的时隙格式。并且，该60KHz下的扩展循环前缀的时隙格式还可以满足第二种传输格式要求，即可以保证SSB的传输。
通过向终端设备指示子载波间隔为60KHz下的普通循环前缀格式对应的符号属性，终端设备仅需要利用60KHz下的普通循环前缀格式和扩展循环前缀的时隙格式之间的映 射关系，确定出60KHz下的扩展循环前缀的时隙格式，可以使得终端设备更加准确的确定出60KHz下的扩展循环前缀格式，降低终端设备确定60KHz下的扩展循环前缀格式的复杂度，容易实现。
在本申请实例中，作为另一种可能的实现方式，网络设备向终端设备发送的时隙格式索引指示符号属性为：
Z 0Z 1DDDD Z 2Z 3DDDD Z 4Z 5，其中，Z 0至Z 5均表示灵活符号或者上行符号，D表示下行符号。
具体而言，对于网络设备向终端设备发送的时隙格式索引对应的时隙表格为子载波间隔为30KHz下的普通循环前缀时隙格式表格，并且，并且，终端设备最终进行上下行数据传输利用的为60KHz下的扩展循环前缀格式的情况下。由于该扩展循环前缀的时隙格式需要保证SSB的传输，该扩展循环前缀的时隙格式需要满足图2所示的时隙格式。由图2所示的30KHz下的普通循环前缀时隙格式和60KHz下的扩展循环前缀时隙格式之间的对应关系，可以看出，在需要保证该扩展循环前缀的时隙格式可以满足SSB的传输的情况下，30KHz下的普通循环前缀时隙格式需要保证：符号2至符号5均为下行符号，符号8至符号11均为下行符号。
因此，对于该时隙格式索引对应的时隙表格为子载波间隔为30KHz下的普通循环前缀格式，并且，该扩展循环前缀的时隙格式为子载波间隔为60KHz下的扩展循环前缀格式的情况下，该时隙格式索引指示的30KHz下的普通循环前缀格的符号属性为：
Z 0Z 1DDDD Z 2Z 3DDDD Z 4Z 5，其中，Z 0至Z 5均表示灵活符号或者上行符号，D表示下行符号。
终端设备可以根据上述的扩展循环前缀的时隙格式和普通循环前缀的时隙格式之间的映射关系或者对应关系，根据30KHz下的普通循环前缀格式，确定出60KHz下的扩展循环前缀格式。并且，确定出的60KHz下的扩展循环前缀格式需要满足：第一种传输格式需要保证符号3至符号10均为下行符号，第二种传输格式需要保证符号1至符号8均为下行符号。而且，其他符号位置上需要包括上行符号U和/或灵活符号F。
对于上述的30KHz下的普通循环前缀格式的符号属性，作为一种可能的实现方式，该时隙格式索引的可能的取值和每个可能的取值指示的14个符号的符号属性可以为表6所示的。

应该理解的是，表6只是示例性的，不应该对该时隙格式索引的取值以及与该时隙格式索引对应的14个符号的符号属性产生限制。例如，表6中时隙格式索引的取值还可以为其他取值等。
终端设备接收到表6所示的任意一个时隙格式索引时，便可以根据该时隙格式索引确定30KHz下的普通循环前缀时隙格式，在确定出30KHz下的普通循环前缀时隙格式后，根据30KHz下的普通循环前缀时隙格式和60KHz下的普通循环前缀时隙格式之间的映射关系，确定出60KHz下的普通循环前缀时隙格式，然后根据60KHz下的普通循环前缀时隙格式和60KHz下的扩展循环前缀时隙格式之间的映射关系，确定出60KHz下的扩展循环前缀格式。并且，确定出的60KHz下的扩展循环前缀格式需要满足SSB的传输，而且，其他符号位置上需要包括上行符号U和/或灵活符号F。即还可以满足URLLC业务的上行传输和下行传输以及传输时延要求。
通过向终端设备指示子载波间隔为30KHz下的普通循环前缀格式对应的符号属性，可以使得终端设备更加准确的确定出60KHz下的扩展循环前缀格式。进一步的，由于只需要通知14个符号的符号属性，可以减少通知该符号属性所占的资源，提高资源的利用率。
在本申请实例中，作为另一种可能的实现方式，网络设备向终端设备发送的时隙格式索引指示符号属性为：
Z 0DD FDD F Z 1DD Z 2DD Z 3，其中，F表示灵活符号，Z 1至Z 3均表示灵活符号或者上行符号，D表示下行符号。
具体而言，对于网络设备向终端设备发送的时隙格式索引对应的时隙表格为子载波间隔为15KHz下的普通循环前缀时隙格式表格，并且，并且，终端设备最终进行上下行数据传输利用的为60KHz下的扩展循环前缀格式的情况下。由于该扩展循环前缀的时隙格式需要保证SSB的传输，该扩展循环前缀的时隙格式需要满足图2所示的时隙格式。由图2所示的15KHz下的普通循环前缀时隙格式和60KHz下的扩展循环前缀时隙格式之间的对应关系，可以看出，在需要保证该扩展循环前缀的时隙格式可以满足SSB的传输的情况下，15KHz下的普通循环前缀时隙格式需要保证：符号1和符号2均为下行符号，符号4和符号5均为下行符号，符号8和符号9均为下行符号，符号11和符号12均为下行符号。
因此，对于该时隙格式索引对应的时隙表格为子载波间隔为15KHz下的普通循环前缀格式，并且，该扩展循环前缀的时隙格式为子载波间隔为60KHz下的扩展循环前缀格式的情况下，该时隙格式索引指示的15KHz下的普通循环前缀格的符号属性为：
Z 0DD FDD F Z 1DD Z 2DD Z 3，其中，F表示灵活符号，Z 0至Z 3均表示灵活符号或者上行符号，D表示下行符号。
终端设备根据15KHz下的普通循环前缀格式，结合上述的不同子载波间隔的普通循环前缀的时隙格式之间的映射关系，确定出60KHz下的普通循环前缀格式，然后再根据普通循环前缀的时隙格式与扩展循环前缀的时隙格式之间的映射关系，确定出60KHz下的扩展循环前缀格式。并且，确定出的60KHz下的扩展循环前缀格式需要满足：第一种传输格式需要保证符号3至符号10均为下行符号，第二种传输格式需要保证符号1至符号8均为下行符号。而且，其他符号位置上需要包括上行符号U和/或灵活符号F。
对于上述的15KHz下的普通循环前缀格式的符号属性，作为一种可能的实现方式，该时隙格式索引的可能的取值和每个可能的取值指示的14个符号的符号属性可以为表7所示的。
表7
Figure PCTCN2020089339-appb-000014
表7所示的时隙表格中，F表示灵活符号，Z 0至Z 3均表示灵活符号或者上行符号，D表示下行符号。
应该理解的是，表7只是示例性的，不应该对该时隙格式索引的取值以及与该时隙格式索引对应的14个符号的符号属性产生限制。例如，表7中时隙格式索引的取值还可以为其他取值等。
终端设备接收到表7所示的任意一个时隙格式索引时，便可以根据该时隙格式索引确定对应的15KHz下的普通循环前缀时隙格式，在确定出15KHz下的普通循环前缀时隙格式后，根据15KHz下的普通循环前缀时隙格式和60KHz下的普通循环前缀时隙格式之间的映射关系，确定出60KHz下的普通循环前缀时隙格式，然后根据60KHz下的普通循环前缀时隙格式和60KHz下的扩展循环前缀时隙格式之间的映射关系，确定出60KHz下的扩展循环前缀格式。并且，确定出的60KHz下的扩展循环前缀格式需要满足SSB的传输，而且，其他符号位置上需要包括上行符号U和/或灵活符号F。即还可以满足URLLC业务的上行传输和下行传输以及传输时延要求。
通过向终端设备指示子载波间隔为15KHz下的普通循环前缀格式对应的符号属性，可以使得终端设备更加准确的确定出60KHz下的扩展循环前缀格式。进一步的，由于只需要通知14个符号的符号属性，可以减少通知该符号属性所占的资源，提高资源的利用率。
对于上述的网络设备向终端设备发送的时隙格式索引对应的时隙表格均为普通循环前缀格式表格的几种情况，即网络设备向终端设备发送的时隙格式索引对应的时隙表格均为普通循环前缀格式表格，表格中的每一行均有14个符号的符号属性。这些表格对应的子载波间隔分别为15KHz、30KHz、60KHz。而终端设备最终是利用子载波间隔为60KHz的扩展循环前缀格式传输上下行数据和SSB。可以看出，这些时隙格式表格中时隙格式索引指示的14个符号的符号属性包括：D和U为连续两个符号，并且，该下行符号D的符号索引小于该上行符号U的符号索引。即可以出现符号D和符号U之间没有F的情况，例如表格4所示的时隙格式表中的符号11和符号12、表格6所示的时隙格式表中时隙格式索引71至87中的符号11和符号12、表格7所示的时隙格式表中的符号9和符号10等。这是因为网络设备向终端设备通知的是普通循环前缀时隙格式的时隙格式的时隙格式索引，终端设备在接收到普通循环前缀时隙格式的时隙格式索引后，确定了该时隙格式索引指示的普通循环前缀时隙格式，还需要根据扩展循环前缀的时隙格式和普通循环前缀的时隙格式之间的映射关系，确定最终传输上下行数据和SSB的扩展循环前缀的时隙格式。即使网络设备通知时隙格式中包括的DU，但是最终映射到扩展循环前缀的时隙格式时就可以在D和U之间出现F。因此，网络设备向终端设备发送的时隙格式索引对应的普通循环前缀格式表格中可以存在两个相邻的符号为DU的符号属性。
通过利用该时隙格式索引指示的14个符号的符号属性中包括D和U为连续两个符号的符号属性，并且D的符号索引小于U的符号索引。可以增加用于指示14个符号的符号属性时隙格式索引的数量，即可以利用更多类型的14个符号的符号属性指示扩展循环前缀格式。实现了14个符号的符号属性更加灵活的指示。并且，终端设备根据该时隙格式索引指示的14符号的符号属性确定出的60KHz下的扩展循环前缀格式满足URLLC上行业务和下行业务的传输，保证了通信质量和效率。
另外，上述的几种可能的实现方式均为网络设备向终端设备发送的时隙格式索引对应的时隙表格均为普通循环前缀格式表格，即表格中的一行均有14个符号的符号属性。终端设备可以根据时隙索引指示的某一种子载波间隔下(例如，15KHz、30KHz、60KHz等)的14个符号的符号属性，结合上述的扩展循环前缀的时隙格式和普通循环前缀的时隙格式之间和/或不同子载波间隔的普通循环前缀的时隙格式之间的映射关系，确定出60KHz下的扩展循环前缀格式。在本申请的另一些可能的实现方式中，网络设备向终端设备发送的时隙格式索引对应的时隙表格也可以为扩展循环前缀格式表格，即表格中的一行均有12个符号的符号属性。终端设备可以根据时隙索引指示的某一种子载波间隔下(例如，15KHz、30KHz、60KHz等)的12个符号的符号属性，结合上述的不同子载波间隔的扩展循环前缀的时隙格式之间的映射关系，可以确定出最终传输上下行数据和SSB某个子载波间隔(例如60KHz子载波间隔)下的扩展循环前缀格式。
下面将具体说明该时隙格式索引指示的为扩展循环前缀时隙格式下的12个符号的符号属性的情况。
对于该时隙格式索引指示的为60KHz子载波间隔对应扩展循环前缀时隙格式的12个符号的属性情况，由于该扩展循环前缀的时隙格式需要保证SSB的传输，该扩展循环前缀的时隙格式需要满足图2所示的时隙格式，即60KHz下的扩展循环前缀格式需要满足：第一种传输格式(或者称为第一种符号属性)需要保证符号3至符号10均为下行符号，相当于保证了图2中60KHz下的扩展循环前缀格式第一个时隙中的时隙格式。第二种传输格式(或者称为第二种符号属性)需要保证符号1至符号8均为下行符号，
因此，对于该时隙格式索引对应的时隙表格为子载波间隔为60KHz下的扩展循环前缀格式，并且，并且，终端设备最终进行上下行数据传输利用的为子载波间隔为60KHz下的扩展循环前缀格式的情况下，该时隙格式索引指示的符号属性包括以下两种符号属性中的至少一种：
第一种符号属性为：A 0A 1A 2DDDDDDDDF，其中，F表示灵活符号，D表示下行符号，A 0至A 2均表示灵活符号、上行符号以及下行符号中的任意一个。
第一种符号属性为：B 0DDDDDDDDB 1B 2B 3，其中，F表示灵活符号，D表示下行符号，B 0表示灵活符号或者上行符号,B 1表示灵活符号或者下行符号，B 2和B 3均表示灵活符号、上行符号以及下行符号中的任意一个。
具体而言，对于第一种符号属性，作为一种可能的实现方式，该时隙格式索引的可能的取值和每个可能的取值指示的12个符号的符号属性可以为表8所示的。

终端设备接收到表9所示的任意一个时隙格式索引时，便可以根据该时隙格式索引确定出60KHz下的扩展循环前缀的时隙格式。该60KHz下的扩展循环前缀的时隙格式包括下行符号D、至少一个上行符号U和至少一个灵活符号F，保证了URLLC上行业务和下行业务的传输。并且，该60KHz下的扩展循环前缀的时隙格式还可以满足第一种传输格式要求，即可以保证SSB的传输。
通过向终端设备指示子载波间隔为60KHz下的扩展循环前缀格式对应的12个符号的符号属性，终端设备可以直接根据指示的60KHz下的扩展循环前缀格式的12个符号上进行上下行数据的传输和SSB的传输。终端设备不需要在进行时隙格式的映射和转换过程。降低了终端设备确定60KHz下的扩展循环前缀格式的复杂度，容易实现。
在本申请实例中，作为另一种可能的实现方式，网络设备向终端设备发送的时隙格式索引指示符号属性为：
Z 0Z 1DDDC 0C 1DDDZ 2Z 3，其中，Z 0表示灵活符号或者上行符号，Z 1表示灵活符号或者下行符号，D表示下行符号，C 0和C 1均表示灵活符号或者下行符号，Z 2表示灵活符号或者下行符号，Z 3表示灵活符号、上行符号以及下行符号中的任意一个。
具体而言，对于网络设备向终端设备发送的时隙格式索引对应的时隙表格为子载波间隔为30KHz下的扩展循环前缀时隙格式表格，并且，终端设备最终进行上下行数据传输利用的为子载波间隔为60KHz下的扩展循环前缀格式的情况下。由于该扩展循环前缀的时隙格式需要保证SSB的传输，因此，对于该时隙格式索引对应的时隙表格为子载波间隔为30KHz下的扩展循环前缀格式，并且，该扩展循环前缀的时隙格式为子载波间隔为60KHz下的扩展循环前缀格式的情况下，该时隙格式索引指示的30KHz下的扩展循环前缀格的符号属性为：

应该理解的是，表10只是示例性的，不应该对该时隙格式索引的取值以及与该时隙格式索引对应的12个符号的符号属性产生限制。例如，表10中时隙格式索引的取值还可以为其他取值等。
终端设备接收到表10所示的任意一个时隙格式索引时，便可以根据该时隙格式索引确定30KHz下的扩展循环前缀时隙格式，在确定出30KHz下的扩展循环前缀时隙格式后，根据30KHz下的扩展循环前缀时隙格式和60KHz下的扩展循环前缀时隙格式之间的关系，确定出60KHz下的扩展循环前缀格式。并且，确定出的60KHz下的扩展循环前缀格式需要满足SSB的传输，而且，其他符号位置上需要包括上行符号U和/或灵活符号F。即还可以满足URLLC业务的上行传输和下行传输以及传输时延要求。
通过向终端设备指示子载波间隔为30KHz下的扩展循环前缀格式对应的符号属性，终端设备仅需要利用60KHz下的扩展循环前缀格式和30KHz的扩展循环前缀的时隙格式之间的映射关系，确定出60KHz下的扩展循环前缀的时隙格式，可以使得终端设备更加准确的确定出60KHz下的扩展循环前缀格式，降低终端设备确定60KHz下的扩展循环前缀格式的复杂度。进一步的，由于只需要通知12个符号的符号属性，可以减少通知该符号属性所占的资源，提高资源的利用率。
在本申请实例中，作为另一种可能的实现方式，网络设备向终端设备发送的时隙格式索引指示符号属性为：
C 0DD DD C 1C 2DD DD C 3，其中，C 0至C 3均表示灵活符号或者下行符号，D表示下行符号。
具体而言，对于网络设备向终端设备发送的时隙格式索引对应的时隙表格为子载波间隔为15KHz下的扩展循环前缀时隙格式表格，并且，并且，终端设备最终进行上下行数据传输利用的为60KHz下的扩展循环前缀格式的情况下。由于该扩展循环前缀的时隙格式需要保证SSB的传输，因此，对于该时隙格式索引对应的时隙表格为子载波间隔为15KHz下的扩展循环前缀格式时，该时隙格式索引指示的15KHz下的扩展循环前缀格的符号属性为：
C 0DD DD C 1C 2DD DD C 3，其中，C 0至C 3均表示灵活符号或者下行符号，D表示下行符号。

应该理解的是，表11只是示例性的，不应该对该时隙格式索引的取值以及与该时隙格式索引对应的12个符号的符号属性产生限制。例如，表11中时隙格式索引的取值还可以为其他取值等。
终端设备接收到表11所示的任意一个时隙格式索引时，便可以根据该时隙格式索引确定15KHz下的扩展循环前缀时隙格式，在确定出15KHz下的扩展循环前缀时隙格式后，根据15KHz下的扩展循环前缀时隙格式和60KHz下的扩展循环前缀时隙格式之间的关系，确定出60KHz下的扩展循环前缀格式。并且，确定出的60KHz下的扩展循环前缀格式需要满足SSB的传输，而且，其他符号位置上需要包括上行符号U和/或灵活符号F。即还可以满足URLLC业务的上行传输和下行传输以及传输时延要求。
通过向终端设备指示子载波间隔为15KHz下的扩展循环前缀格式对应的符号属性，终端设备仅需要利用60KHz下的扩展循环前缀格式和15KHz的扩展循环前缀的时隙格式之间的映射关系，确定出60KHz下的扩展循环前缀的时隙格式，可以使得终端设备更加准确的确定出60KHz下的扩展循环前缀格式，降低终端设备确定60KHz下的扩展循环前缀格式的复杂度。进一步的，由于只需要通知12个符号的符号属性，可以减少通知该符号属性所占的资源，提高资源的利用率。
上述分别利用时隙格式索引对应的时隙表格为子载波间隔为15KHz下的扩展循环前 缀时隙格式表格、子载波间隔为30KHz下的扩展循环前缀时隙格式表格、子载波间隔为60KHz下的扩展循环前缀时隙格式表格为例进行说明。对于时隙格式索引指示一行为12个符号的扩展循环时隙格式，这12个符号可以为相同的子载波间隔对应的普通循环前缀的14个符号中的12个符号。例如，可以为普通循环前缀的14个符号中的前12个符号或者后12个符号，或者为普通循环前缀的14个符号中的第1个符号(符号索引为0)到第6个符号(符号索引为5)以及第8个符号(符号索引为7)到第13个符号(符号索引为12)。或者还以为普通循环前缀的14个符号中其他位置的12个符号等。可以理解的，终端设备从时隙表格中的14个符号中确定12个符号的位置。终端设备根据12个符号的位置上的符号属性，确定扩展循环前缀时隙对应的12个符号的属性。
例如，对于上述的60KHz的扩展循环前缀时隙格式索引指示的第一种符号属性：A 0A 1A 2DDDDDDDDF，这12个符号可以为上述的60KHz的普通循环前缀时隙格式索引指示的第一种符号属性中的14个符号的第1个符号到第6个符号(符号索引为0至5)以及第8个符号到第13个符号(符号索引为7至12)。结合表8和表4进行说明。对于上述的表格8所示的60KHz的扩展循环前缀时隙格式索引表格，每个时隙格式索引指示的12个符号可以为表格4所示的所示的60KHz的普通循环前缀时隙格式索引表格中对应的时隙格式索引指示的13个符号中的第1个符号到第6个符号(符号索引为0至5)以及第8个符号到第13个符号(符号索引为7至12)。
又例如，对于上述的30KHz的扩展循环前缀时隙格式索引指示的符号属性：Z 0Z 1DDDC 0C 1DDDZ 2Z 3，这12个符号可以为上述的30KHz的普通循环前缀时隙格式索引指示的14个符号属性中的14个符号中的前12个符号，或者后12个符号，或者为该30KHz的普通循环前缀的14个符号中的第1个符号(符号索引为0)到第6个符号(符号索引为5)以及第8个符号(符号索引为7)到第13个符号(符号索引为12)。
又例如，对于上述的15KHz的扩展循环前缀时隙格式索引指示的符号属性：C 0DD DD C 1C 2DD DD C 3，这12个符号可以为上述的15KHz的普通循环前缀时隙格式索引指示的14个符号属性中的14个符号中的前12个符号，或者后12个符号。
网络设备通过利用该时隙格式索引指示的符号为该时隙格式表中的一行指示的14个符号中的前12个符号，或者后12个符号，或者第1个符号到第6个符号以及第8个符号到第13个符号。可以使得网络设备更加准确和方便的确定出该时隙格式索引指示的12符号的符号属性，降低了网络设备确定该时隙格式索引指示的12符号的符号属性的复杂度，容易实现。并且，终端设备根据该时隙格式索引指示的12符号的符号属性确定出的60KHz下的扩展循环前缀格式可以满足URLLC上行业务和下行业务的传输，并且可以保证SSB的传输。保证了通信质量和效率。
还应理解的是，上述仅仅以网络设备向终端设备发送的时隙格式索引指示的时隙表格对应的子载波间隔为15KHz子载波间隔、30KHz子载波间隔以及60KHz子载波间隔中的任意一种，而该终端设备根据该时隙格式索引，确定的为60KHz子载波间隔下扩展循环前缀的时隙格式为例进行说明。在本申请实施例中，网络设备向终端设备发送的时隙格式索引指示的时隙表格对应的子载波间隔还可以为15KHz子载波间隔、30KHz子载波间隔、60KHz子载波间隔、120KHz子载波间隔以及240KHz子载波间隔中的任意一种或者多种，而该终端设备根据该时隙格式索引，确定的还可以为15KHz子载波间隔下扩展循环前缀 的时隙格式、30KHz子载波间隔下扩展循环前缀的时隙格式、120KHz子载波间隔下扩展循环前缀的时隙格式或者240KHz子载波间隔下扩展循环前缀的时隙格式的中的任意一种。并且，网络设备向终端设备发送的时隙格式索引指示的时隙表格对应的子载波间隔小于或等于终端设备需要根据该时隙格式索引确定的扩展循环前缀的时隙格式对应的子载波间隔。
在本申请的一些实例中，以图4为例，在图3所示的方法步骤的基础上，该方法200还包括S209。

图4中所示的S210至S230描述可以参考上述对S210至S230的描述，为了简洁，这里不再赘述。
在S209中，终端设备可以向网络设备上报终端设备支持接收扩展循环前缀对应的一个时隙的时隙格式索引，和/或支持接收扩展循环前缀对应的SS/PBCH block的能力信息。即终端设备可以利用上述的第一指示信息向网络设备指示自己支持利用扩展循环前缀时隙格式传输的数据或者控制信息。进一步的，该扩展循环前缀时隙格式对应的子载波间隔可以为15KHz子载波间隔、30KHz子载波间隔、60KHz子载波间隔、120KHz子载波间隔以及240KHz子载波间隔中的任意一种或者多种。终端设备向网络设备上报自己支持接收利用扩展循环前缀的时隙发送的数据或者控制信息后，网络设备便可以执行S210和S220的步骤，向终端设备发送时隙格式索引，该时隙格式索引用于终端设备确定扩展循环前缀的时隙格式。终端设备确定了扩展循环前缀的时隙格式后，便可以在该扩展循环前缀的时隙格式中接收SSB，以及在该扩展循环前缀的时隙格式中发送上行数据和接收下行数据。

图5中所示的S210至S230描述可以参考上述对S210至S230的描述，为了简洁，这里不再赘述。
在S208中，网络设备还可以向终端设备发送第二指示信息，第二指示信息可以用于指示终端设备接收扩展循环前缀对应的一个时隙的时隙格式索引，和/或接收扩展循环前缀对应的SS/PBCH block。例如，在当终端设备不支持接收扩展循环前缀ECP对应的一个时隙的时隙格式索引，和/或不支持接收ECP对应的SS/PBCH block的能力信息的情况下，网络设备可以配置终端设备接收扩展循环前缀对应的一个时隙的时隙格式索引，和/或支持接收扩展循环前缀对应的SS/PBCH block。在这种情况下，网络设备通过第二指示信息(或者也可以称为配置信息)配置终端设备支持接收扩展循环前缀对应的一个时隙的时隙格式索引，和/或支持接收扩展循环前缀对应的SS/PBCH block。之后，网络设备便可以执行S210和S220的步骤，向终端设备发送时隙格式索引，该时隙格式索引用于终端设备确定扩展循环前缀的时隙格式。终端设备确定了扩展循环前缀的时隙格式后，便可以在该扩展循环前缀的时隙格式中接收SSB，以及在该扩展循环前缀的时隙格式中发送上行数据和 接收下行数据。
