随着5G NR系统MTC和物联(internet of things，IoT)通信的普及，越来越多的IoT设备已经部署在人们的生活中。例如：智能水表、共享单车，以及智慧城市、环境监测、智能家居、森林防火等以传感和数据采集为目标的设备等等。而未来，IoT设备将是无处不在的，可能会嵌入每一件衣服、每一个包裹、每一把钥匙，几乎所有的离线物品都将在物联网技术的赋能下实现在线。但与此同时，由于IoT设备分布范围广泛、数量众多，所以实现万物互联的过程也给产业界带来了不小的挑战，首当其冲的便是供电问题。目前，IoT仍然主要由运营商推动，IoT模块需要使用标准蜂窝协议与基站通讯。由于基站需要覆盖尽可能大的面积，因此IoT模块需要能做到在距离基站很远时仍能进行通信，这就使得IoT设备在无线通信时仍然需要消耗高达30mA的电流，所以目前的IoT模块仍然需要使用较高容量的电池才能工作，这也导致了IoT模块的尺寸很难做小，增加了IoT设备的成本。
此外，一些低功耗终端在医疗、智能家居、工业传感器、可穿戴设备等物联网应用中发挥着重要作用。然而，由于这类终端尺寸大小有限，如果要延长这些设备的运 行时间，很难通过简单的提高电池容量来实现。因此，要实现延长终端续航时间，需降低无线通信的功耗，其中，无线电收发器则是最耗电的组件之一。
因此，为了能进一步普及IoT，把IoT模块植入人体内，或者更小的物件中，则不可能再搭配较高容量的电池，而必须使用更小的电池甚至彻底摆脱电池的限制，或者是设计一种降低无线电收发器功耗的方法，进而来克服IoT设备的成本、尺寸、功耗等的限制问题。因此，2021年6月，在3GPP在组织R18潜在研究方向讨论会中，讨论了物联网增强技术，且披露了5G演进(5G-Advanced)将从R18开始，在5G NR系统中引入无源(Passive)IoT和WUR。Passive IoT是从目前大量且成熟使用RFID技术中得出启发后应运而生。因为省去了电源模块，所以无源RFID产品的体积可以达到厘米量级甚至更小，而且自身结构简单，成本低，故障率低，使用寿命较长。
下面首先对RFID技术和WUR技术进行说明。
一、RFID技术：是一种非接触式的自动识别技术，其可以通过射频信号自动识别目标对象并获取相关数据。
通常情况下，RFID系统由阅读器(reader)和标签(tag)组成。结合图2a所示，阅读器通过向标签发送激励信号为标签进行充能，标签接收阅读器发送的信令，并以反射通信的方式向阅读器发送反射信号。通过这种方式，阅读器可以识别标签的标识(identity document，ID)，以及对标签进行读写等操作。
需要说明的是，阅读器向标签发送的激励信号可以是下文中的下行数据或下行数据中的一种，反射信号可以是下文中的上行数据或上行数据中的一种。该下行数据为连续载波，标签以反射通信的方式向阅读器发送反射信号，具体可以是，标签利用下行数据提供的载波进行上行数据的传输。
目前，为了扩展RFID的有效工作距离，通常采用以下两种方式：
方式1、分离式架构：结合图2b所示，分离式的阅读器包括辅助器(helper)和接收器(receiver)。helper通过前向链路向标签发送激励信号，receiver通过反向链路从标签接收反射信号，另外receiver生成RFID相关的下行信令，并通过前传链路向helper发送下行信令，再由helper在前向链路上进行转发。
方式2、集中式或一体式架构：结合图2c所示，除了阅读器与标签间通过前向链路和反向链路进行信号的激励和反射之外，阅读器还与集中控制单元(如基站)进行通信，集中控制单元可以对阅读器使用的前向链路的资源和发送行为进行的调度、控制等。
本申请实施例中，为了实现在NR系统中支持RFID，上述方式1中的helper和receiver之间，以及上述方式2中的阅读器和集中控制单元之间可以通过NR技术进行通信。
二、WUR技术：功耗大的主连接无线电(primary connection radio，PCR)，也可以称作主接收机，进入休眠状态后，通过功耗低的伴连接无线电(Companion Radio)，也称作唤醒接收机(WUR)监听AP发送的唤醒帧，在监听到唤醒帧后对PCR进行唤醒。
结合图3a所示，接收端设备310中部署有主接收机311和唤醒接收机312。在发射端设备320(例如AP或者终端设备)未发送数据时，主接收机关闭，也称作处于休 眠状态，唤醒接收机开启；结合图3b所示，在发射端设备320发送数据时，首先发送唤醒数据(例如上述唤醒帧)，接收端设备310通过唤醒接收机311接收到唤醒数据后激活主接收机312，使主接收机开启，也称作处于激活状态，此时接收端设备310通过主接收机311接收发射端设备320在唤醒数据后发送的数据。
需要说明的是，唤醒机的信息比特被调制成开关键(on-off keying，OOK)符号，发射端设备利用这些OOK符号来屏蔽生成的窄带正交频分复用(orthogonal frequency division multiplexing，OFDM)波形(即OOK波形)，从而进一步优化OOK波形，OOK符号承载在13个子载波上，在电气和电子工程师协会(institute of electrical and electronics engineers，IEEE)定义的无线局域网标准IEEE 802.11ba中称为多载波(multicarrier，MC)OOK。在接收端设备侧，OOK解调不需要频域和时域上的任何信道均衡，因此接收端设备通过唤醒接收机进行非相干检测(如包络检测)进行监听。使用非相干检测，接收端设备不需要保持/跟踪高精度的振荡速率。因此，可以避免锁相环，进一步降低接收侧功耗。
应理解的是，OOK符号仅为WUR唤醒帧的一种示例，并不对本申请构成任何限定。
针对NR系统中应用的RFID技术，例如可以称作无源(Passive)IoT。本申请提供的Passive IoT与RFID的传输机制类似。在Passive IoT中，Passive IoT设备(例如标签)可以是无源(Batter Free)的，即Passive IoT设备自身不配备或不主要依赖于电池或者有线电源来供电。但是，Passive IoT设备不具备电源模块并不意味着不需要用电，Passive IoT设备可以从环境光、热量、射频中获取能量，从而支撑起物联网数据的感知、无线传输和分布式的计算等等。Passive IoT设备也可以是储能无源的，还可以是半无源的。储能无源设备有储能设备。半无源设备有电池，但电池供电仅对标签内要求供电维持数据的电路或者标签芯片工作所需电压的辅助支持，本身耗电很少的标签电路供电，电池尺寸也相对较小。
参考图4和图5，图4和图5示例性示出Passive IoT通信中的上下行通信方法示意图。
如图4所示，图4示例性示出Passive IoT下行通信方法示意图。
标签通过下行链路向阅读器发送调幅信号，标签接收该调幅信号，可以采用包络检波器，对该调幅信号进行包络检波，获取其中的低频信号。包络检波器的主要组成部分包括图4所示的二极管和电阻-电容电路(resistor-capacitance circuit，RC)，也即振荡电路。
上述包络检波是指：从调幅信号中将低频信号解调出来的过程，广义的检波通常称为解调，是调制的逆过程，即从已调信号提取调制信号的过程。对调幅信号来说，包络检波就是从它的振幅变化中提取调制信号的过程。其中，包络是反映一个高频信号的幅度变化曲线，当用一个低频信号对一个高频信号进行幅度调制时，低频信号就成了高频信号的包络线。
可以理解的是，图4所示出的包络检波电路为最传统的基础电路结构示意图，关于包络检波电路的演进结构，在此在暂不赘述。本申请实施例对标签采用的包络检波电路结构不作限制。
如图5所示，图5示例性示出Passive IoT上行通信方法示意图。
标签自身无法提供电源，也无条件连接有线电源，来供标签进行数据传输。所以标签需要从外接环境中获取能量，进而提供标签进行数据传输，以及数据处理等其他操作。
具体的，当标签接收阅读器发出的载波信号，可以利用空间中产生的电磁场得到的能量，驱动芯片将自身存储的信息传送出去。
在上述实现方法中，阅读器和标签的关系为“电磁反向散射耦合”关系，“电磁反向散射耦合”是指利用电磁波的空间传播规律，当发射的电磁波接触到被测物体后，携带着被测物体的信息被反射回来。这种耦合适合用在高频、微波工作的远距离射频识别系统。
可以理解的是，图5所示的Passive IoT通信中上行通信方法仅为示例，在本申请另一些实施例中，标签还可以通过获取环境光、热等能量，来驱动芯片将自身存储的信息传送出去。如前所述，标签也可以是储能无源设备或者半无源设备。
上述Passive IoT设备在NR系统中进行通信存在的问题包括至少以下两个方面：
一方面，在NR中，网络设备(例如基站)会周期性广播定时信息，终端设备可以随时获取定时信息(比如帧号，时隙号等)，而且终端设备晶振同步精度高，能较好维持定时，因此NR系统中终端设备可以根据当前时隙号和从网络设备接收的时隙配置(例如时分双工(time division duplexing，TDD)的时隙配置、频分双工(frequency division duplex，FDD)的时隙配置等)确定当前的时隙为下行时隙还是上行时隙。对于PassiveIoT来说，阅读器按需(on demand)向标签发送下行信令，标签获取定时机会较少，此外标签的同步能力较弱，维持定时能力较差，因此对于Passive IoT，采用阅读器直接通知时隙配置的方式，无法使标签基于与阅读器同步的定时，确定收发资源，进而无法与阅读器在NR系统中进行通信。
另一方面，在NR中，终端设备利用自身生成的载波进行上行传输，而Passive IoT中，标签的上行传输是反射通信，即标签自身不产生载波，是采用阅读器的下行数据提供的载波，标签对接收到的载波进行调制和反射以传输数据。
应理解，Passive IoT仅为一种示例性的名称，当其替换为其他表述时也属于本申请保护范围。
还应理解，上述Passive IoT场景下的信息交互流程、信令格式仅为一种示例，而非限制性的说明。
针对NR系统中应用的WUR技术，需要说明的是：
在NR中，网络设备(例如基站)会周期性广播定时信息，终端设备，包括终端设备中的主接收机，可以随时获取定时信息(比如帧号，时隙号等)，而且终端设备有比较好的同步能力，能比较好维持定时，因此终端设备可以根据当前时隙号和从网络设备接收的时隙配置(例如TDD的时隙配置、FDD的时隙配置等)确定当前的时隙为下行时隙还是上行时隙。然而，对于唤醒机来说，网络设备按需(on demand)向开启WUR的终端设备发送下行信令，开启WUR的终端设备获取定时机会较少，并且唤醒机的同步能力较弱，维持定时能力较差，因此对于WUR，采用网络设备直接通知时隙配置的方式，无法使唤醒机基于与网络设备同步的定时，确定收发资源，进而无法与 网络设备在NR系统中进行通信。
由此可见，第一设备(例如标签、唤醒机等)与第二设备(例如阅读器、AP、发射侧终端设备)之间，如何在NR系统中确定传输资源，并在该传输资源上进行上行数据和/或下行数据的传输是当前亟待解决的问题。
针对上述问题，本申请实施例提供一种传输资源的确定方案，使第一设备与第二设备之间能够在NR系统中进行数据传输。
为便于理解本申请实施例，做出如下几点说明：

图6为本申请实施例提供的一种通信方法400的示意性交互流程示意图。如图6所示，该方法400可以包括S410和S420。下面对方法200中的各个步骤做详细说明。
S410，第一设备确定从通信的起始位置开始的时域资源，该时域资源包括第一时域资源和第二时域资源，第一时域资源和第二时域资源之间间隔第一间隔时长，该第一时域资源的时域长度与第一传输时长相关，该第二时域资源的时域长度为第二传输时长；

S420-2，第一设备在该时域资源上发送上行数据，相应的，第二设备在该时域资源上接收第一设备发送的上行数据。
上述S420-1和上述S420-2可以择一执行，或者依次执行，例如第一设备接收第二设备发送的下行数据后，向第二设备发送上行数据。以实现第一设备与第二设备通过该时域资源进行通信。
示例性的，第二设备确定从通信的起始位置开始的时域资源，并通过该时域资源向第一设备发送下行数据，第一设备确定从通信的起始位置开始的时域资源，并在该时域资源接收第二设备发送的下行数据；和/或，第一设备确定从通信的起始位置开始的时域资源，并在该时域资源向第二设备发送上行数据，第二设备确定从通信的起始位置开始的时域资源，并在该时域资源接收第一设备发送的上行数据。
可以理解的是，第二设备与第一设备的实现方式相同或者相似，下文中仅以第一设备确定从通信的起始位置开始的时域资源为例进行说明。
需要说明的是，在第一设备接收第二设备发送的下行数据时，该下行数据由帧头和数据部分组成，通信的起始位置例如可以是下行数据的帧头携带的指示信息指示的；或者，该下行数据由前导序列和数据部分组成，第二设备可以根据前导序列获取时间和/或频率同步，也可以确定时间单元的边界，时间单元可以为符号或时隙或子帧或帧，其中，前导序列位于数据部分之前，前导序列和数据部分在时域上可以是连续的，也可以是不连续的。通信的起始位置可以根据前导序列的起始位置，或者，通信的起始 位置可以根据前导序列的结束位置确定，或者，通信的起始位置可以根据数据部分的起始位置确定，比如，通信的起始位置为前导序列的起始位置或者为前导序列的结束位置或者为根据数据部分的起始位置。
需要说明的是，在第一设备向第二设备发送上行数据时，该上行数据由帧头和数据部分组成，通信的起始位置例如可以是上行数据的帧头携带的指示信息指示的；或者，该上行数据由前导序列和数据部分组成，第二设备可以根据前导序列获取时间和/或频率同步，也可以确定时间单元的边界，时间单元可以为符号或时隙或子帧或帧，其中，前导序列位于数据部分之前，前导序列和数据部分在时域上可以是连续的，也可以是不连续的。通信的起始位置可以根据前导序列的起始位置，或者，通信的起始位置可以根据前导序列的结束位置确定，或者，通信的起始位置可以根据数据部分的起始位置确定，比如，通信的起始位置为前导序列的起始位置或者为前导序列的结束位置或者为根据数据部分的起始位置。通信的起始位置可以由第一设备确定，或者由第二设备通知给第一设备。
其中，第一传输时长可以是第一设备和/或第二设备中预定义的；或者第一传输时长可以是预配置的，例如当第一传输时长仅在第一设备中预定义时，第一设备可以向第二设备发送信令配置该第一传输时长，当第一传输时长仅在第二设备中预定义时，第二设备可以向第一设备发送信令配置该第一传输时长；或者第一传输时长可以是协议中定义的。
与第一传输时长类似的，第二传输时长和第一间隔时长也可以是预定义的、预配置的或者协议中定义的，此处不再赘述。
应理解，第一传输时长和第二传输时长可以相同也可以不同。
本申请实施例可以适用于任一双工模式，尤其适用于TDD模式。下面以应用于TDD模式进行示例性的说明。应理解，TDD模式中，时隙配置可以包括单周期时隙配置和双周期时隙配置。
在上述单周期时隙配置中，第一传输时长和第二传输时长可以相同。结合图7a所示，TDD的每个周期包括3个下行时隙，1个上行时隙和1个灵活时隙，例如TDD的周期P＝2.5ms，第一传输时长和第二传输时长相同，均为3个时隙，也即第一时域资源和第二时域资源的时域长度相同。
示例性的，时域资源还包括第三时域资源，结合图7a所示，该第三时域资源与第二时域资源之间间隔第一间隔时长，且该第三时域资源的时域长度为第一传输时长。
换言之，时域资源可以以P周期内的图案(pattern)进行重复。
应理解，图7a所示的TDD模式下单周期的时隙配置为一种示例，但不对单周期的时隙配置构成任何限定，例如其中至少一个时隙可以不仅为一种类型的时隙，如图7a中的第4、9、14个时隙可以由上行符号、灵活符号、下行符号中的至少两种组成。相应的，第一传输时长和第二传输时长的单位可以是时隙或者符号，也即第一时域资源、第二时域资源、第三时域资源均可以包括n1个时隙加m1个符号、n2个时隙或m2个符号，其中n1、m1、n2、m2均为正整数。
在上述双周期时隙配置中，第一传输时长和第二传输时长一般不同。结合图7b所示，TDD的周期包括第一周期P1和第二周期P2，第一周期P1包括3个下行时隙、1 个灵活时隙、1个上行时隙，第二周期P2包括2个下行时隙、1个灵活时隙和2个上行时隙，例如第一周期P1＝5ms，第二周期P2＝5ms。第一传输时长为3个时隙，第二传输时长为2个时隙，也即第一时域资源和第二时域资源的时域长度不同。
示例性的，时域资源还包括第三时域资源，结合图7b所示，该第三时域资源与第二时域资源之间间隔第二间隔时长，且该第三时域资源的时域长度为第一传输时长。可以理解的是，第三时域资源之后还可以包括第四时域资源，第四时域资源与第三时域资源之间间隔第一间隔时长，且该第四时域资源的时域长度为第二传输时长。
换言之，时域资源可以以P1和P2周期内的图案进行重复。
应理解，图7b所示的TDD模式下双周期的时隙配置为一种示例，但不对双周期的时隙配置构成任何限定，例如其中至少一个时隙可以不仅为一种类型的时隙，如图7b中的第4、8、14个时隙可以由上行符号、灵活符号、下行符号中的至少两种组成。相应的，第一传输时长和第二传输时长的单位可以是时隙或者符号，也即第一时域资源、第二时域资源、第三时域资源均可以包括n3个时隙加m3个符号、n4个时隙或m4个符号，其中n3、m3、n4、m4均为正整数。
可以理解的是，当第一设备在第一时域资源接收完全部下行数据时，该时域资源仅包括该第一时域资源，当第一设备在第一时域资源未接收完全部下行数据时，第一设备在第二时域资源上继续接收下行数据，该时域资源包括第一时域资源和第二时域资源，以此类推，直至第一设备接收完全部下行数据时结束。
第一设备向第二设备发送上行数据的过程与此类似，依次在第一时域资源、第二时域资源、第三时域资源……上发送上行数据，直至完成上行数据的发送，时域资源包括第一设备发送上行数据实际占用的时域资源。
在一些实施例中，时域资源中的第一时域资源、第二时域资源、第三时域资源……，均包括上行时隙、上行符号、灵活时隙、灵活符号中的至少一种，且时域资源中的第一时域资源、第二时域资源、第三时域资源……中相邻两个之间间隔的资源包括下行时隙、下行符号、灵活时隙、灵活符号中的至少一种；或者，时域资源中的第一时域资源、第二时域资源、第三时域资源……，均包括下行时隙、下行符号、灵活时隙、灵活符号中的至少一种，且时域资源中的第一时域资源、第二时域资源、第三时域资源……中相邻两个之间间隔的资源包括上行时隙、上行符号、灵活时隙、灵活符号中的至少一种。
例如，在第一设备接收第二设备发送的下行数据时，时域资源中的第一时域资源、第二时域资源、第三时域资源……均为下行时隙、下行符号、灵活时隙、灵活符号中的至少一种；在第一设备向第二设备发送上行数据时，时域资源中的第一时域资源、第二时域资源、第三时域资源……均为上行时隙、上行符号、灵活时隙、灵活符号中的至少一种，此种情况下，用于第一设备与第二设备通信的时域资源与NR系统中TDD的时隙配置相应，降低了上下行传输的干扰。
进一步的，保证时域资源的边界与现有时间单元(时隙/符号)的边界对齐，避免造成现有网络无法调度的时域资源碎片(如半个符号)，减少对现有网络时域资源调度的影响。
可选的，时域资源中第一传输时长和第二传输时长对应的第一时域资源、第二时 域资源、第三时域资源……与任一间隔时长对应的时域资源也可以为同类型的时域资源，例如第一传输时长和第二传输时长对应的时域资源和任一间隔时长对应的时域资源均包括上行传输资源(例如至少一个上行时隙和/或至少一个上行符号)，或者第一传输时长和第二传输时长对应的时域资源和任一间隔时长对应的时域资源均包括下行传输资源(例如至少一个下行时隙和/或至少一个上行符号)。
可选的，时域资源中第一传输时长和第二传输时长对应的第一时域资源、第二时域资源、第三时域资源……中的任一资源可以即包括上行传输资源又包括下行传输资源(例如包括1个上行时隙和1个下行时隙)，与此类似的，任一间隔时长对应的时域资源也可以即包括上行传输资源又包括下行传输资源。
需要说明的是，时域资源的起始位置，也即第一时域资源的起始位置可以是上述通信的起始位置，例如时图7a中周期P的起始位置或者图7b中第一周期P1的起始位置。然而，在一些实施例中，第一时域资源的起始位置也可以不是通信的起始位置，其与通信的起始位置之间存在偏移量，此时第一时域资源的时域长度可以小于或者大于第一传输时长，该偏移量可以为时隙数、符号数等。示例性的，结合图8a和图8b所示，第一设备可以将通信的起始位置与偏移量的和确定为第一时域资源的起始位置，假设偏移量为1个时隙加2个符号，图8a和图8b中第一时域资源的起始位置向后移动至图示位置，假设偏移量为负值，则第一时域资源的起始位置向前移动至对应的时隙位置。
可选的，第一设备可以将通信的起始位置和偏移量的乘积或者商确定为第一时域资源的起始位置。
在一些实施例中，第一设备可以在不同的频域资源上分别接收第二设备发送的下行数据，以及向第二设备发送上行数据。例如，第一设备可以在上述时域资源和第一频域资源上接收第二设备发送的下行数据，第一设备可以在上述时域资源和第二频域资源上向第二设备发送上行数据。其中，第一频域资源和第二频域资源之间存在频域间隔。此种情况下，可以避免第一设备在相同的频率上既发送上行数据又接收下行数据，提高了传输的可靠性。
该第一频域资源可以是第一设备和/或第二设备中预定义的；或者可以是预配置的，例如当第一频域资源仅在第一设备中预定义时，第一设备可以向第二设备发送信令配置该第一频域资源，当第一频域资源仅在第二设备中预定义时，第二设备可以向第一设备发送信令配置该第一频域资源；或者第一频域资源可以是协议中定义的。
与第一频域资源类似的，第二频域资源也可以是预定义的、预配置的或者协议中定义的，此处不再赘述。
在另一些实施例中，还可以以上述预定义、预配置或协议定义的方式预设频域间隔。此种情况下，第一设备和第二设备可以根据第一频域资源和频域间隔，确定第二频域资源，或者根据第二频域资源和频域间隔，确定第一频域资源。
假设第一设备为标签，第二设备为阅读器，第二设备在时域资源和第一频域资源向第一设备发送的下行数据，可以是连续载波，该连续载波可以是给定频率下的正弦波或余弦波，或者，连续载波对应的波形没有经过幅度和/或相位调制，或者，连续载波对应的波形经过幅度和/或相位调制，但整体的幅度不足以被第一设备解释为传输数 据。
第一设备在时域资源和第二频域资源向第二设备发送上行数据，具体可以是第一设备在时域资源和第二频域资源向第二设备以反射通信的方式发送上行数据。例如，第一设备通过对接收的连续载波进行调制，作为上行数据的载波，将上行数据反射给第二设备。
可选的，时域资源在第一频域资源上包括上行时隙、上行符号、灵活时隙、灵活符号中的至少一种，该时域资源在第二频域资源上包括下行时隙、下行符号、灵活时隙、灵活符号中的至少一种；或者，该时域资源在第一频域资源上包括下行时隙、下行符号、灵活时隙、灵活符号中的至少一种，该时域资源在第二频域资源上包括上行时隙、上行符号、灵活时隙、灵活符号中的至少一种。当时域资源在第一频域资源上包括下行传输资源，在第二频域资源上包括上行传输资源时，可以避免第一设备和第二设备之间的传输与NR系统的数据传输不同向带来的干扰，提高了传输的可靠性。
需要说明的是，时域资源可以包括上述第一时域资源、第二时域资源、第三时域资源……，或者时域资源可以是配置信息配置的任一段时域资源。
图9为本申请实施例提供的一种通信方法500的示意性交互流程示意图。如图9所示，该方法500还可以包括S430和S440中至少之一。
S440，第二设备向第一设备发送配置信息，相应的，第一设备接收第二设备发送的配置信息。
需要说明的是，该配置信息可以包括前述第一传输时长和/或第一间隔时长。
在一些实施例中，第一传输时长和第二传输时长不同，则配置信息还可以包括第二传输时长。
在一些实施例中，配置信息还可以包括第二间隔时长。
在一些实施例中，配置信息还可以包括前述偏移量。
在一些实施例中，配置信息还可以包括频域间隔信息，该频域间隔信息用于指示第一频域资源和第二频域资源之间的频域间隔。
应理解，上述配置信息中的全部信息均可以独立发送，也可以一同发送。例如第二设备可以将频域间隔信息可以作为独立的信息发送至第一设备进行配置。
假设第一设备为部署有唤醒接收机的终端设备，第一设备可以通过主接收机接收第二设备(例如网络设备)发送的配置信息，该配置信息可以通过无线资源控制(radio resource control，RRC)释放(Release)消息携带。
在一些实施例中，第一设备可以将接收到的配置信息进行存储。
可选的，第一设备可以对接收到的配置信息设置对应的预设定时器，在预设定时器超时时，第一设备确定该配置信息无效，在预设定时器未超时时，确定该配置信息有效。
示例性的，第二设备向第一设备发送频域间隔信息之前，可以执行如下S430：
S430，第一设备向第二设备发送能力信息，相应的，第二设备接收该第一设备发送的能力信息，该能力信息用于指示第一设备支持的第一频域资源和第二频域资源之间的最大频域间隔。
进一步的，第二设备基于该最大频域间隔确定第一频域资源和第二频域资源之间 的频域间隔，避免向第一设备配置的频域间隔超出第一设备的能力范围。
假设第一设备为部署有唤醒接收机的终端设备，第一设备向第二设备发送的能力信息还可以包括指示是否支持唤醒接收机的信息。
假设第一设备为部署有唤醒接收机的终端设备，第一设备还可以向第二设备发送辅助信息，该辅助信息可以包括终端设备的节能等级、终端设备偏好的寻呼接收方式或者请求开启唤醒接收机等信息中的至少一个。其中，终端设备偏好的寻呼接收方式可以包括通过主接收机接收寻呼、通过唤醒接收机接收寻呼，或者通过唤醒接收机和主接收机接收寻呼。
可选的，上述能力信息和辅助信息均可以通过四步随机接入过程中的消息一或消息三携带，或者，通过两步随机接入过程中的消息A，或者通过终端能力信息(UECapabilityInformation)或终端辅助信息(UEAssistanceInformation)携带。对于NR系统，四步随机接入过程和两步随机接入过程的具体描述见TS 3GPP 38.300 V16.7.0中9.2.6节。
一般来说，上述S430和S440在S410之前执行。
因此，本申请实施例中第一设备确定从通信的起始位置开始的时域资源，并在该时域资源上与第二设备进行通信，使第一设备和第二设备能够在各通信系统(例如NR通信系统)中进行通信，也即实现了IoT与其他通信系统的融合。
进一步的，第一设备确定的时域资源包括第一时域资源和第二时域资源，且第一时域资源和第二时域资源之间间隔第一间隔时长，使得第一设备不需要维护定时信息(例如帧号、时隙号等)，即可确定能够通信的时间段和不能通信的时间段，降低了第一设备的复杂度，进而降低第一设备的成本。
图10为本申请实施例提供的一种通信方法600的示意性交互流程示意图。如图10所示，该方法600可以包括S610至S640中的部分或者全部过程。下面对S610至S640进行解释。
S610，第一设备向第二设备发送能力信息，相应的，第二设备接收该第一设备发送的能力信息，该能力信息用于指示第一设备支持的第一频域资源和第二频域资源之间的最大频域间隔；
S620，第二设备向第一设备发送配置信息，相应的，第一设备接收第二设备发送的配置信息；
S630，第二设备在第二频域资源以及第二频域资源对应的时域资源发送下行数据，相应的，第一设备在第二频域资源以及第二频域资源对应的时域资源接收下行数据；
S640，第一设备在第一频域资源以及第一频域资源对应的时域资源发送上行数据，相应的，第二设备在第一频域资源以及第一频域资源对应的时域资源接收上行数据。
上述S630和上述S640可以择一执行，或者依次执行，例如第一设备接收第二设备发送的下行数据后，向第二设备发送上行数据。以实现第一设备与第二设备通过该时域资源进行通信。
需要说明的是，第一频域资源对应的时域资源和第二频域资源对应的时域资源均包括至少一个第一时间单元，该第一时间单元在第一频域资源对应的时域资源上为第一资源类型，该第一时间单元在第二频域资源对应的时域资源上为第二资源类型。
其中，第一资源类型下的第一时间单元包括上行时隙、灵活时隙、上行符号或灵活符号，第二资源类型下的第一时间单元包括下行时隙、灵活时隙、下行符号或灵活符号。
需要说明的是，第一频域资源、第二频域资源、第一频域资源对应的时域资源、第二频域资源对应的时间资源均可以为预定义的、预配置的或者协议定义的。
在一种可能的实现方式中，第一频域资源、第二频域资源、第一频域资源对应的时域资源、第二频域资源对应的时间资源中的至少之一可以由S620中，第二设备向第一设备发送的配置信息进行配置。
可选的，第一频域资源对应的时域资源和第二频域资源对应的时域资源均可以包括上述第一时域资源、第二时域资源、第三时域资源……，或者时域资源均可以是配置信息配置的任一段时域资源。
图11a至图11d示出了几种可能的时频资源，图11a至图11d中任一图中虚线框标注的资源包括至少一个第一时间单元，第一设备和第二设备可以选择其中的虚线框内的一个或多个时频资源进行通信。
结合图11a和图11b所示，将相同时长内第一资源类型对应的时间单元的个数与所述第二资源类型对应的时间单元的个数的比作为第一比例，例如第一资源类型下的时间单元可以包括上行时隙、灵活时隙、上行符号或灵活符号中的至少一种，第二资源类型下的时间单元可以包括下行时隙、灵活时隙、下行符号或灵活符号中的至少一种。在图11a中，第一频域资源和第二频域资源分别对应的第一比例相同，例如第一比例均为2比8。其中，相同时长可以是一个周期或者是约定值；在图11b中，第一频域资源和第二频域资源分别对应的第一比例互为倒数，例如第一频域资源对应的第一比例为2比8，第二频域资源对应的第一比例为8比2。
结合图11c所示，第一频域资源对应的全部时间单元均为第一资源类型，例如均为上行时隙，第二频域资源对应的全部时间单元均为第二资源类型，例如均为下行时隙。
可选的，时间单元为时域单位，但不一定是最小的时域单元，例如可以是时隙、符号等。
结合图11d所示，第一频域资源对应的全部时间单元为同一资源类型，例如均为上行时隙，第二频域资源对应的全部时间单元非同一资源类型；或者，(图中未示出)第一频域资源对应的全部时间单元非同一资源类型，第二频域资源对应的全部时间单元为同一资源类型。
针对上述S620需要说明的是，第二设备可以向第一设备发送第一时频资源配置信息和第二时频资源配置信息。其中，第一时频资源配置信息用于配置第一频域资源和第一频域资源对应的时域资源；第二时频资源配置信息用于配置第二频域资源和/或第二频域资源对应的时域资源。
当第二时频资源配置信息不用于配置第二频域资源对应的时域资源时，第一设备和/或第二设备可以根据第一频域资源对应的时域资源确定第二频域资源对应的时域资源，例如第一设备和/或第二设备确定第一频域资源对应的时域资源和第二频域资源对应的时域资源为相同的时域资源。
当第二时频资源配置信息用于配置第二频域资源时，第二时频资源配置信息可以包括频域间隔信息或第二频域资源的配置信息。其中，第二频域资源的配置信息可以直接指示第二频域资源，频域间隔信息则用于指示第二频域资源与第一频域资源之间的频域间隔。示例性的，当第二时频资源配置信息包括频域间隔信息时，第一设备和/或第二设备可以根据第一频域资源和频域间隔信息确定第二频域资源。
应理解的是，上述第一时频配置信息和第二时频配置信息中的至少一个，可以包括图9所示实施例中任一示例的配置信息。
针对上述S610需要说明的是，该能力信息用于指示第一频域资源和第二频域资源之间的最大频域间隔。通过该最大频域间隔可以约束第一频域资源与第二频域资源之间的频域间隔，例如，约束第一频域资源与第二频域资源之间的频域间隔小于或等于最大频域间隔。
示例性的，能力信息对第一频域资源和第二频域资源之间的频域间隔的约束力，可以通过第二设备实现，例如第二设备基于第一设备上报的能力信息，确定第一频域资源和第二频域资源之间的频域间隔，使该频域间隔小于或等于能力信息指示的最大频域间隔，并将该频域间隔通过配置信息发送给第一设备，使第一设备确定用于通信的第一频域资源和第二频域资源。
可以理解的是，S610中的能力信息还可以包括前述图9中S430中所示例的一种或多种能力信息。
图12为本申请实施例提供的一种盘存流程示意图。结合图11所示，下面将以第一设备为标签、第二设备为阅读器为例，对本申请实施例提供的通信方法进行说明。
需要说明的是，如下盘存过程适用于统计任意部署或者携带有标签的物品的数量。例如在汽车上部署标签，可以通过阅读器对某一路段的车辆数进行统计；在库存的衣服、鞋子、饰品上携带标签，可以对库存中各类物品的数量进行统计；在牛、羊上携带标签，可以对牧区的牛或羊的数量进行统计。
可选的，盘存操作中阅读器可以读取标签的产品电子码(electronic product code，EPC)
下面通过阅读器和标签之间的信息交互，对盘存过程进行说明。
S710，阅读器向标签发送选择(select)命令；
S720，阅读器向标签发送查询(query)命令；
S730，标签生成随机数；
S740，阅读器向标签发送重复查询(queryrep)命令；
S750，标签向阅读器发送反馈标识(如16位随机数RN16)；
S760，阅读器向标签发送应答命令(如确认字符(acknowledge character，ACK)命令或否定确认(negative acknowledgment，NAK)命令)；
S770，标签向阅读器发送EPC。
针对上述S710，需要说明的是：在盘存之前，阅读器可以使用一个或多个Select命令选择一个特定的标签群。select命令可以连续使用多次，符合多次Select命令的标签才响应，可以实现类似哈希(hash)或布隆(bloom)滤波的操作，降低碰撞概率、提高盘存标签的效率。
针对上述S720，需要说明的是：在初始化链路参数，设置标签内部随机时隙计数器后,query命令开启一轮盘存周期，并初始化下行数据率、上行数据率和编码方式、会话(session)、目标(target)、Q值等参数。
在上述S730中，符合Sel和target的标签生成随机数，其中Sel为query命令中的字段的名称，并将随机数置入时隙计数器，标签状态由准备(ready)状态转为仲裁(arbitrate)状态。
标签在时隙计数器的值为0时，返回16位随机数RN16，标签状态由arbitrate转为reply；否则保持静默，维持arbitrate状态。
应理解，标签通过在时隙计数器的值为0时反馈RN16，可以避免多个标签同时向阅读器发送反馈标识，带来的数据冲突(或数据碰撞)的问题。
在标签为返回RN16时，阅读器执行S740，直至接收到标签发送的RN16。需要说明的是，RN16仅为一种示例，标签还可以向阅读器发送任一反馈标识，以实现阅读器对该标识的识别。
针对S740需要说明的是，queryrep命令用于递减标签的时隙计数器，每个选中标签的时隙计数器-1。如果时隙计数器的值为0，则标签返回RN16；否则保持静默。
针对S760需要说明的是，阅读器若成功接收到RN16，则返回包含该RN16的ACK命令；阅读器若接收RN16失败，则可返回NAK命令，此时标签进入Arbitrate状态，且盘存标志位不改变。
针对S770需要说明的是，标签收到ACK命令后，返回EPC信息；阅读器收到EPC后即完成对该标签的盘存。返回EPC后的标签处于确认(acknowledged)状态，当收到query、调节查询(queryadjust)、queryrep命令后会回到ready状态，且盘存标志会翻转，避免在此次盘存周期内重复响应。其中EPC是产品电子代码，用于标识所附着的物品。
上述S710至S770中，select命令、query命令、queryrep命令、queryadjust命令、应答命令中的至少一个命令中，可以携带配置信息，该配置信息可以包括前已述及的任意一种或者多种可被配置的信息，例如配置信息可以包括第一传输时长、第二传输时长、第一间隔时长、第二间隔时长、频域间隔信息、第一时频资源配置信息、第二时频资源配置信息中的至少一种，各配置信息的解释如前所述。
此外，上述配置信息中还可以包括预编码变换的使能信息，通过预编码变换的使能信息，阅读器可以向标签指示是否使能(enable)预编码变换(transform precoder)，如果使能预编码变换，则数据传输的波形为基于傅立叶变换扩展的正交频分复用(DFT-S-OFDM)，如果去使能预编码变换，则数据传输的波形为循环前缀正交频分复用(CP-OFDM)。
可选的，上述S710中的select命令为阅读器与标签之间首次传输的信令，select命令在传输时使用的时域资源中可以没有第一间隔时长和/或第二间隔时长对应的资源，即阅读器尽量在连续的下行时间单元内发送完select命令，或者，阅读器按照一个预设的图案发送select命令，比如select命令每传输一个第一传输时长后，间隔一个第一间隔时长，第一传输时长和第一间隔时长可以为约定值，该约定值阅读器和标签均可获知。
