在本申请实施例的描述中，术语“对应”可表示两者之间具有直接对应或间接对应的关系，也可以表示两者之间具有关联关系，也可以是指示与被指示、配置与被配置等关系。
本申请实施例可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统、蜂窝物联网、蜂窝无源物联网或其他通信系统等。

本申请实施例结合终端设备和通信设备描述了各个实施例，如上所述，该通信设备可以是网络设备，其中：网络设备可以是用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及NR网络中的网络设备(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
在本申请实施例中，终端设备(User Equipment，UE)也可以称为用户设备、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等。终端设备可以是WLAN中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、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)设备、具有无线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、可穿戴设备以及下一代通信系统，例如，NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备，又或者是零功耗设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
应理解的是，零功耗设备可以被理解为功耗低于预设功耗的设备，例如包括：无源终端，甚至还包括半无源终端等。近年来，零功耗设备的应用越来越广泛。一种典型的零功耗设备是RFID(Radio Frequency Identification)，它是利用无线射频信号空间耦合的方式，实现无接触的标签信息自动传输与识别的技术。RFID标签又称为“射频标签”或“电子标签”。根据供电方式的不同来划分的电子标签的类型，可以分为有源电子标签，无源电子标签和半无源电子标签。有源电子标签，又称为主动式电子标签，是指电子标签工作的能量由电池提供，电池、内存与天线一起构成有源电子标签，不同于被动射频的激活方式，在电池更换前一直通过设定频段发送信息。无源电子标签，又称为被动式电子标签，其不支持内装电池，无源电子标签接近读写器时，标签处于读写器天线辐射形成的近场范围内电子标签天线通过电磁感应产生感应电流，感应电流驱动电子标签芯片电路。芯片电路通过电子标签天线将存储在标签中的标识信息发送给读写器。半无源电子标签，又被称为半主动式电子标签，其继承 了无源电子标签体积小、重量轻、价格低、使用寿命长的优点，内置的电池在没有读写器访问的时候，只为芯片内很少的电路提供电源，只有在读写器访问时，内置电池向RFID芯片供电，以增加标签的读写距离较远，提高通信的可靠性。
应理解的是，通常无源电子标签被理解为零功耗设备，有些情况下半无源电子标签也被理解为零功耗设备。
RFID是一种无线通信技术。图2为本申请提供的RFID系统的示意图，如图2所示，最基本的RFID系统是由电子标签(TAG)和读写器(Reader/Writer)两部分构成。电子标签：它由耦合组件及芯片构成，每个电子标签都有独特的电子编码，放在被测目标上以达到标记目标物体的目的。读写器：不仅能够读取电子标签上的信息，而且还能够写入电子标签上的信息，同时为电子标签提供通信所需要的能量。如图2所示。电子标签进入电磁场后，接收读写器发出的射频信号，无源电子标签或者被动电子标签利用空间中产生的电磁场得到的能量，将电子标签存储的信息传送出去，读写器读取信息并且进行解码，从而识别电子标签。
基于零功耗设备的通信，简称零功耗通信，包括以下关键技术：
1、反向散射通信(Back Scattering)
图3为本申请提供的反向散射通信原理图，如图3所示，零功耗设备，即反向散射标签接收反向散射读写器发送的载波信号，通过射频(Radio Frequency，RF)能量采集模块，即能量采集模块采集能量，进而对低功耗处理模块，即图3中的逻辑处理模块进行供能，对载波信号进行调制，并进行反向散射。
应理解的是，由于上述反向散射读写器发送的载波信号用于向反向散射标签提供能量，因此该载波信号也被称为供能信号，基于此，本申请所涉及的供能信号在一些情况下也被称为载波信号，载波信号在一些情况下也被称为供能信号。
应理解的是，图3所示的反向散射通信原理是通过反向散射标签和反向散射读写器说明的，实际上，任何具有反向散射通信功能的设备以及发射载波信号，用于提供能量的设备都可以实现反向散射通信。
反向散射通信原理主要特征如下：
(1)终端设备不主动发射信号，通过调制来波信号实现反向散射通信；
(2)终端设备不依赖传统的有源功放发射机，同时使用低功耗计算单元，极大降低硬件复杂度；
(3)结合能量采集可实现免电池通信。
因此，这里的终端设备可以是零功耗设备(如无源终端，甚至是半无源终端)，甚至该终端设备可以是非零功耗设备，如普通终端，但是该普通终端可以在有些情况下进行反向散射通信。
2、能量采集(RF Power Harvesting)
图4为本申请实施例提供的能量采集原理图，如图4所示，终端设备可以利用RF能量采集模块通过电磁感应实现对空间电磁波能量的采集，进而实现对负载电路的驱动(低功耗运算、传感器等)，可以实现免电池。
3、负载调制
负载调制是电子标签经常使用的向读写器传输数据的方法。负载调制通过对电子标签振荡回路的电参数按照数据流的节拍进行调节，使电子标签阻抗的大小和相位随之改变，从而完成调制的过程。负载调制技术主要有电阻负载调制和电容负载调制两种方式。
在电阻负载调制中，负载并联一个电阻，称为负载调制电阻，该电阻按数据流的时钟接通和断开，开关S的通断由二进制数据编码控制。电阻负载调制的电路原理图如下图5所示。在电容负载调制中，负载并联一个电容，取代了图5中由二进制数据编码控制的负载调制电阻。
4、编码
电子标签传输的数据，可以用不同形式的代码来表示二进制的“1”和“0”。无线射频识别系统通常使用下列编码方法中的一种：反向不归零(Non Return Zero，NRZ)编码、曼彻斯特(Manchester)编码、单极性归零(Unipolar RZ)编码、差动双相(DBP)编码、米勒(Miller)编码利差动编码。通俗的说，就是用不同的脉冲信号表示0和1。
NR系统中的灵活时隙
NR系统中引入了灵活的时隙格式，即在一个时隙中包括下行(Downlink，DL)符号、灵活(Flexible)符号和上行(Uplink)符号。其中，灵活符号具有下面的特征：
(1)灵活符号表示该符号的方向的未定的，可以通过其他信令将其改变为下行符号或者上行符号；
(2)灵活符号也可以表示为了前向兼容性，预留给将来用的符号；
(3)灵活符号用于终端的收发转换，类似于LTE TDD系统中的保护间隔保护间隔(Guard Period，GP)符号，终端在该符号内完成收发转换；
在NR系统中，定义了多种灵活时隙格式，包括全下行时隙、全上行时隙、全灵活时隙，以及不同下行符号、上行符号、灵活符号个数的时隙格式，不同的时隙格式分别对应一个时隙格式索引。
NR系统支持多种方式配置时隙格式，包括：通过半静态上下行配置信令配置时隙格式和通过动态上下行指示信令配置时隙格式，其中，半静态上下行配置信令包括tdd-UL-DL-ConfigurationCommon和tdd-UL-DL-ConfigurationDedicated，动态上下行指示信令即格式2-0的下行控制信令(Downlink control information，DCI)。
网络设备通过发送tdd-UL-DL-ConfigurationCommon信令配置公共的时隙格式，即对于小区内的所有的终端都适用的时隙格式，该信令可以配置一个或两个图案(pattern)，每个图案对应一个周期。在每个图案中，网络设备可以配置该图案中的时隙格式，主要包括如下参数：参考子载波间隔(μ ref)、周期P，即该图案的周期参数，其单位为ms、下行时隙数(d slots)、下行符号数(d sym)、上行时隙数(u slots)、上行符号数(u sym)。
根据参考子载波间隔和周期可以确定该周期内包括的时隙个数总数S，该S个时隙中的前d slots个时隙表示全下行时隙，最后一个全下行时隙的下一个时隙中的前d sym个符号表示下行符号；该S个时隙中的最后u slots个时隙表示全上行时隙，第一个全上行时隙的前一个时隙中的最后u sym个符号表示上行符号；该周期中的其余的符号表示灵活符号。因此，在一个图案周期内，整体看来配置的帧结构形式也是下行时隙或符号在前，上行时隙或符号在后，中间是灵活时隙或符号。终端根据tdd-UL-DL-ConfigurationCommon可以确定一个周期内的时隙格式，以周期P在时域上重复即可确定所有时隙的时隙格式。
图6为一种TDD上下行配置图案示意图，如图6所示，图中示出了一个图案的时隙配置，该图案的周期P＝5ms，对于15kHz子载波间隔，该图案周期内包括5个时隙，其中d slots＝1，d sym＝2，u slots＝1，u sym＝6，即表示在5ms的周期内，第1个时隙为全下行时隙，第2个时隙中的前2个符号是下行符号，最后一个时隙是全上行时隙，倒数第二个时隙中的最后6个符号是上行符号，其余的符号是灵活符号，该图案在时域上以5ms周期性重复。
tdd-UL-DL-ConfigurationDedicated信令只能改变tdd-UL-DL-ConfigurationCommon配置为灵活符号的方向。如果tdd-UL-DL-ConfigurationCommon配置信令已经配置为下行符号，则不能通过tdd-UL-DL-ConfigurationDedicated信令将其修改为上行符号。如果tdd-UL-DL-ConfigurationCommon配置信令已经配置为上行符号，则不能通过tdd-UL-DL-ConfigurationDedicated信令将其修改为下行符号。
例如，图7为另一种TDD上下行配置图案示意图，网络设备通过tdd-UL-DL-ConfigurationCommon配置信令配置的一个图案的时隙格式如图7所示，在此基础上，网络设备通过tdd-UL-DL-ConfigurationDedicated信令配置两个时隙的时隙格式，如图7所示，这两个时隙分别是5ms周期内的时隙1和时隙2：
时隙1：tdd-UL-DL-ConfigurationDedicated信令配置时隙1的下行符号个数是2个，上行符号个数是4个；
时隙2：tdd-UL-DL-ConfigurationDedicated信令配置时隙2的下行符号个数是3个，上行符号个数是2个。
在通过半静态上下行配置信息配置时隙格式的基础上，网络设备还可以通过时隙格式指示信息(Slot Format Indicator，SFI)动态配置每个时隙的时隙格式，该SFI即是格式2-0的DCI，用SFI-无线网络临时标识(RNTI Radio Network Tempory Identity，RNTI)加扰。SFI只能配置半静态上下行配置信息配置为灵活符号的方向，不能改变半静态配置信息配置为上行符号或下行符号的方向。
SFI指示可以同时配置多个服务小区的时隙格式，网络设备通过无线资源控制(Radio Resource Control，RRC)信令配置小区索引，以及该小区索引对应的时隙格式组合标识(slotFormatCombinationId)的起始比特在格式2-0的DCI中的位置。网络设备配置多个时隙格式组合(slotFormatCombination)，每个时隙格式组合对应一个标识信息(slotFormatCombinationId)以及一组时隙的时隙格式配置，每个时隙格式配置用于配置一个时隙的时隙格式。
SFI包括SFI索引(SFI-index)，该SFI-index即对应于slotFormatCombinationId，根据该索引即可确定一组时隙格式。该SFI指示的时隙格式适用于从承载该SFI信令的时隙开始的连续的多个时隙中，并且SFI指示的时隙个数大于或等于承载该SFI的物理下行控制信道(Physical Downlink Control Channel，PDCCH)的监测周期。如果一个时隙被两个SFI信令指示时隙格式，这个时隙被两个SFI信令指示的时隙格式应该是相同的。
网络设备在配置一个服务小区的时隙格式时，会同时配置一个子载波间隔，即SFI参考子载波间隔μ SFI，该子载波间隔小于或等于监测SFI信令的服务小区的子载波间隔μ，即μ≥μ SFI，此时SFI指示的一个时隙的时隙格式适用于
Figure PCTCN2021106205-appb-000001
个连续的时隙，并且SFI信令指示的每个下行符号或上行符号或灵活符号对应于
Figure PCTCN2021106205-appb-000002
个连续的下行符号或上行符号或灵活符号。
对TDD系统，通信设备不能同时进行接收和发送，因此，NR引入了如上灵活的时隙格式。而对于上述无源终端，甚至一些半无源终端或者有源终端，可能在有些情况无法使用电池供电，而是需要通过其他通信设备对其进行供能，那么在这种情况下，终端设备如何获取时隙格式是本申请亟待解决的技术问题。
下面将对本申请技术方案进行详细阐述：
图8为本申请实施例提供的一种无线通信方法的流程图，该方法可以由终端设备执行，该终端设备具有反向散射通信功能。该终端设备可以是零功耗设备，如无源终端，甚至是半无源终端，也可以由非零功耗设备，即普通设备执行，但是该普通终端可以在有些情况下进行反向散射通信。如图8所示，该方法包括如下步骤：
S810：终端设备接收第一信号，该第一信号包括用于指示时隙格式的指示信息。其中，终端设备通过通信设备供能。
应理解的是，向终端设备供能的通信设备可以是如下的第一通信设备，该第一通信设备是终端设备根据时隙格式进行数据传输的通信设备。该第一通信设备可以是网络设备或者终端设备，但不限于此。或者，向终端设备供能的通信设备可以是如下的第二通信设备，该第二通信设备是不同于第一通信设备的通信设备。该第二通信设备可以是网络设备或者终端设备，但不限于此。又或者，向终端设备供能的通信设备可以是除第一通信设备、第二通信设备的其他通信设备，本申请对此不做限制。
应理解的是，用于产生上述第一信号的通信设备与用于向终端设备供能的通信设备可以是同一通信设备，也可以是不同的通信设备，本申请对此不做限制。
在一些可实现方式中，用于产生上述第一信号的通信设备可以对上述指示信息采用如下编码方式，但不限于此：脉冲间隙编码(pulse-interval encoding，PIE)、反向不归零编码、曼彻斯特(Manchester)编码、单极性归零(Unipolar RZ)编码、差动双相(DBP)编码、米勒(Miller)编码利差动编码。示例性的，通信设备可以对指示信息采用曼彻斯特(Manchester)编码，如图9所示。
应理解的是，用于产生上述第一信号的通信设备对指示信息进行编码，以形成该指示信息对应的编码序列，其中，不同的编码序列对应不同的指示信息，即编码序列与指示信息之间存在映射关系。
应理解的是，第一信号是一种无线射频载波信号，用于产生上述第一信号的通信设备可以通过对该载波信号进行调制，以承载编码后的指示信息。常用的调制方式包括如下几项，但不限于此：振幅键控(Amplitude Shift Keying，ASK)、频移键控(Frequency Shift Keying，FSK)和相移键控(Phase Shift Keying，PSK)等。ASK如双边带振幅移动键控(Double-Sideband Amplitude Shift Keying，DSB-ASK)，单边带振幅移动键控(Single-Sideband Amplitude Shift Keying，SSB-ASK)，或者反相振幅移动键控(Phase-Reversal Amplitude Shift Keying，PR-ASK)。
在一些可实现方式中，该第一信号可以是供能信号或者不是供能信号，本申请对此不做限制。
示例性的，如图1A所示的通信系统100，第一通信设备110可以产生供能信号，该供能信号包括：用于指示时隙格式的指示信息。应理解的是，对于TDD系统，通信设备不能同时进行接收和发送，因此，第一通信设备110在上行时隙只能接收终端设备发送的数据，但是不能向终端设备发送任何信息、数据或者信号等。即第一通信设备110只能在下行时隙发送供能信号，基于此，上述用于指示时隙格式的指示信息只能在下行时隙上发送。
示例性的，如上所述，对于TDD系统，通信设备不能同时进行接收和发送，因此，第一通信设备在上行时隙只能接收终端设备发送的数据，但是不能向终端设备发送任何信息、数据或者信号等。但是在一些特殊情况下，如当前存在连续的多个时隙，如果第一通信设备需要向终端设备发送上述指示信息，只能等到下行时隙才可以，这样将导致指示信息传输时延较大的问题。因此，本申请可以引入第二通信设备，该第二通信设备可以向终端设备供能。如图1B所示的通信系统200，第二通信设备220可以产生供能信号，该供能信号包括：用于指示时隙格式的指示信息。
示例性的，如上所述，对于TDD系统，通信设备不能同时进行接收和发送，因此，第一通信设备在上行时隙只能接收终端设备发送的数据，但是不能向终端设备发送任何信息、数据或者信号等。但是在一些特殊情况下，如当前存在连续的多个时隙，如果第一通信设备需要向终端设备发送上述指示信息，只能等到下行时隙才可以，这样将导致指示信息传输时延较大的问题。因此，本申请可以引入第二通信设备，该第二通信设备可以在上行时隙向终端设备供能。而第一通信设备可以在下行时隙向终端设备供能。如图1B所示的通信系统200，第二通信设备220可以在上行时隙产生供能信号， 以向终端设备230供能，该供能信号包括：用于指示时隙格式的指示信息。第一通信设备210可以在下行时隙产生供能信号，以向终端设备230供能，该供能信号包括：用于指示时隙格式的指示信息。
在一些可实现方式中，当第二通信设备向第一通信设备供能时，第二通信设备可以在第一通信设备的控制下产生的供能信号，例如：第一通信设备可以控制第二通信设备产生供能信号的时间，频段等，本申请对此不做限制。
在一些可实现方式中，当第二通信设备向第一通信设备供能时，第二通信设备是在第一通信设备的控制下发送的指示信息，例如：第一通信设备可以控制第二通信设备发送该指示信息的时间，频段等，本申请对此不做限制。
在一些可实现方式中，上述为终端设备供能的通信设备可以持续发送该供能信号，也可以间歇性的发送该供能信号，本申请对此不做限制。
在一些可实现方式中，当通信设备间歇性的发送该供能信号时，供能信号之间的时间间隔可以是预定义的或者配置的，本申请对此不做限制。
应理解的是，由于通信设备可以与终端设备进行通信，因此，还会存在用于数据或者信息传输的信号。而上述供能信号和用于信息传输的信号可以是一个信号或者是两个独立的信号，本申请对此不做限制。例如：在蜂窝无源物联网中，这两个信号是两个独立的信号。在RFID技术中，这两个信号是一个信号。
在一些可实现方式中，当上述供能信号和用于信息传输的信号是两个独立的信号时，这两个信号可以在一个频段上发送，也可以不在一个频段上发送。
综上，在本申请中，对于上述无源终端，甚至一些半无源终端或者有源终端，可能在有些情况无法使用电池供电，通信设备可以向这类终端设备发送第一信号，该信号包括：用于指示时隙格式的指示信息，以使这类终端设备获取到时隙格式。
在一些可实现方式中，上述指示信息指示的时隙格式是周期性时隙格式。即指示信息用于指示多个时隙集合的时隙格式，也就是说，多个时隙集合为连续的多个时隙集合，且多个时隙集合的时隙格式相同。例如：这多个时隙集合中包括多个连续的时隙集合，每个时隙集合包括：4个时隙，第1个时隙为全下行时隙，第2个时隙中的前2个符号是下行符号，最后一个时隙是全上行时隙，倒数第二个时隙中的最后6个符号是上行符号，其余的符号是灵活符号。
在一些可实现方式中，第一信号携带的指示信息是半静态指示信息和/或动态指示信息。
应理解的是，与现有NR系统类似，网络设备需要提供公共的配置信息用于指示小区的时隙格式，如该公共的配置信息是tdd-UL-DL-ConfigurationCommon，而通过网络配置的tdd-UL-DL-ConfigurationDedicated信令可以改变tdd-UL-DL-ConfigurationCommon配置为灵活符号的方向，以针对某终端设备进一步的配置时隙格式。这两个配置信息都是半静态配置信息。而在本申请中，第一信号携带的指示信息可以类似于这种NR系统中的半静态配置信息。例如，该指示信息包括以下至少一项，但不限于此：周期P，即该图案的周期参数，其单位为ms、下行时隙数(d slots)、下行符号数(d sym)、上行时隙数(u slots)、上行符号数(u sym)、符号长度、码元长度、针对终端设备，至少一个灵活符号的方向。其中，与NR系统内类似，一个时隙可以若干个符号，周期P可以包含若干个时隙。
进一步地，在NR系统中，在通过半静态上下行配置信息配置时隙格式的基础上，网络设备还可以通过SFI动态配置每个时隙的时隙格式，因此，本申请提供的指示信息还可以进一步地指示每个时隙的时隙格式。也就是说，第一信号携带的指示信息包括：半静态指示信息和动态指示信息。示例性的，可以参考表1所示的动态指示信息，每个动态指示信息可以用于指示对应的时隙格式。
表1

Figure PCTCN2021106205-appb-000004
应理解的是，上述U表示上行符号，D表示下行符号，F表示灵活符号。
应理解的是，上述第一信号可以只携带上述的半静态指示信息，这时终端设备可以只根据该半静态指示信息确定时隙格式，或者，上述第一信号可以只携带上述的半静态指示信息，并且动态指示信息可以携带在其他信号中，该其他信号可以是产生第一信号的通信设备，也可以不是产生第一信号的通信设备，这时终端设备可以根据该半静态指示信息和动态指示信息确定时隙格式。又或者，上述第一信号可以只携带上述的动态指示信息，而上述半静态指示信息可以携带在其他信号中，该其他信号可以是产生第一信号的通信设备，也可以不是产生第一信号的通信设备，这时终端设备可以根据该半静态指示信息和动态指示信息确定时隙格式。再或者，上述第一信号携带半静态指示信息和动态指示信息，这时终端设备可以根据该半静态指示信息和动态指示信息确定时隙格式。
在一些可实现方式中，如果第一信号同时携带半静态指示信息和动态指示信息，该半静态指示信息和动态指示信息可以是一个整体，也可以是两个独立的指示信息，本申请对此不做限制。
综上，在本申请中，对于上述无源终端，甚至一些半无源终端或者有源终端，可能在有些情况无法使用电池供电，通信设备可以向这类终端设备发送第一信号，该信号包括：用于指示周期性时隙格式的指示信息，以使这类终端设备获取到周期性时隙格式。
应理解的是，在上一实施例中，时隙格式是周期性时隙格式。终端设备得到该周期性时隙格式后，可以根据周期确定后续时隙的格式。这种方式的前提是终端设备能够获得同步，确定相应的帧、时隙、符号定时等。而对于本申请涉及的终端设备来说，其同步状态的维持依赖于供能信号提供的能量。当供能信号中断时，这类终端设备进入无电状态时，之前获得的同步状态将会丢失。即使这类终端设备一直有供能信号提供能量，由于这类终端设备本地时钟的定时精度较差，例如不具备精度高的晶振器件，不能确定准确的上下行定时，因此即使得到了时隙格式，由于无法维持准确的定时，这类终端设备无法确定上下行时隙的边界。因此，在本实施例中，第一信号携带的指示信息可以用于指示一个时隙集合的时隙格式。在该时隙集合的范围内，终端设备可以维持准确的定时，从而根据该时隙格式可以确定该时隙集合中的时隙格式。
示例性的，图10为本申请一实施例提供的指示信息指示时隙格式的示意图，如图10所示，连续两个时隙的时隙格式通过该两个时隙之前的时隙上承载的指示信息进行指示。其中，例如，指示信息10110010和01100101分别指示不同的时隙格式组合。
综上，在本申请中，对于上述无源终端，甚至一些半无源终端或者有源终端，可能在有些情况无法使用电池供电，通信设备可以向这类终端设备发送第一信号，该信号包括：用于指示非周期性时隙格式的指示信息，以使这类终端设备获取到非周期性时隙格式。此外，该指示信息除了指示时隙格式之外，还可以用于终端设备进行定时调整，从而获得准确的时隙边界，也就是说，终端设备不需要依赖于定时信息，而是通过时隙格式可以获得一个时隙集合的时隙格式，同时可以获得准确的时隙定时。
在一些可实现方式中，上述指示信息是周期性指示信息。示例性的，图11为本申请另一实施例提供的指示信息指示时隙格式的示意图，如图11所示，该指示信息是10110010，其周期性发送，并且每个指示信息可以指示对应的时隙结构，如图11所示的是一个指示信息可以指示时隙0至时隙4构成的时隙集合的时隙格式。
在一些可实现方式中，上述指示信息是非周期性指示信息。
应理解的是，非周期性指示信息一般是在某种事件触发下发送的指示信息，因此，该指示信息也被称为触发性指示信息或者事件触发性指示信息，本申请对此不做限制。
在一些可实现方式中，该非周期性指示信息与以下任一项具有关联关系：上行传输、下行传输、上行时隙与下行时隙之间的转换。也就是说，上行传输、下行传输、上行时隙与下行时隙之间的转换中的至少一项可以触发非周期性指示信息。
综上，在本申请中，指示信息可以周期性发送或者非周期性发送，从而可以提高指示信息发送的灵活性。
