为了便于清楚描述本申请实施例的技术方案，以下，对本申请实施例中所涉及的部分术语和技术进行简单介绍：

网络节点，在本申请中可以指Ambient IoT中网络侧、或者Reader、或者中继节点、或者辅助节点。
其他术语
在本申请实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。例如，第一芯片和第二芯片仅仅是为了区分不同的芯片，并不对其先后顺序进行限定。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
在本申请实施例中，“在……时”、以及“在……情况下”，均指一种条件。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
在本申请实施例中，“至少一个(项)”是指一个(项)或者多个(项)，“多个(项)”是指两个(项)或两个(项)以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A，B可以是单数或者复数。

接着对相关技术进行说明。
在相关技术中，按照物联网节点的不同速率，可以将物联网分为高速物联网、中速物联网和低速物联网三种类型。
高速物联网主要通过5G增强型移动宽带(eMBB)、4G Cat.4+、第六代无线网络技术(WiFi 6)等技术来承载。
中速物联网目前主要通过4G Cat.1、3G、2G等技术来承载。中速物联网支持十亿级的物联网连接。
低速物联网主要由窄带物联网(Narrow Band Internet of Things，NB-IoT)、(Long Range Wide Area Network，LoRaWAN)、蓝牙低能耗(Bluetooth Low Energy，BLE)等技术来承载。低速物联网支持百亿级的物联网连接。
目前，物联网中可以采用无线射频识别(即射频识别(Radio Frequency Identification，RFID))技术，来实现识别目标和数据交换的目的。RFID技术是一种自动识别技术，其支持通过无线射频方式进行非接触的双向数据通信，利用无线射频方式对记录媒体(电子标签或射频卡)进行读写，以实现识别目标和数据交换的目的。
RFID技术支持的覆盖距离只有10米(m)左右，而且不支持干扰管理和移动性管理等技术，难以支持未来千亿级的物联网连接。因此，3GPP中正讨论制定基于蜂窝通信的无源物联网的技术。无源物联网可以支持千亿级的物联网连接，能够应用于工业传感、物流和仓储、智能可穿戴、医疗健康、以及智能家居等场景。
目前，3GPP正在讨论制定基于蜂窝通信的无源物联网技术(例如支持干扰管理、以及移动性等)，以在支持千亿级的物联网连接的情况下，可以利用已有的大规模的蜂窝基础设施的基础上，降低成本，还可以利用蜂窝通信许多成熟的技术，提升无源物联网的覆盖范围。
在无源物联网中，为了降低终端的成本和功耗，在3GPP中引入了以下三种类型的终端：
装置(Device)1：无能量存储，无独立信号生成/放大，即反向散射传输。
装置2A：具有能量存储，没有独立的信号生成，即反向散射传输。存储能量的使用可以包括对反射信号的放大。
装置2B：具有能量存储，具有独立的信号生成功能，即用于传输的有源射频(Radio Frequency，RF)组件。
在3GPP中，为了简化涉及，下行只引入PRDCH，上行只引入PDRCH。
至少研究以下选项用于指示PRDCH的传输结束时刻：选项1，R2D后同步紧跟在PRDCH之后，表示PRDCH结束；选项2，基于R2D控制信息。
至少研究以下选项用于指示PDRCH的传输结束时刻：选项1，D2R后同步紧跟在PDRCH之后；选项2，基于控制信息。
在Ambient IoT中，采用预设调制类型(例如二进制启闭键控(On-Off Keying，OOK)调制)，在频域上的带宽有限，主要通过时域传递信息，因此需要指示在时域上信道的传输结束时刻。
鉴于此，本申请实施例提供一种通信方法，本申请实施例提供的通信方法可以适用于下述通信系统中：5G(5th Generation，第五代)，4G(4th Generation，第四代)，3G(3rd Generation，第三代)等3GPP中涉及的通信系统。还可适用于未来新的各种通信系统，例如6G(6th Generation，第六代)、7G(7th Generation，第七代)等，本申请实施例对此并不限定。还适用于无线保真(WIFI)等无线通信系统中。在本申请实施例提供的方法中，基于控制信息得到信道的传输结束时刻，从而解决需要指示在时域上信道的传输结束时刻。

S102、第一通信设备基于控制信息，得到信道的传输结束时刻。
可选地，信道可以为在Ambient IoT中的相关信道，还可以为其他应用场景中的信道。例如相关信道的名称可以为PRDCH或者PDRCH，还可以为其它名称。
例如，在第二通信设备为网络节点、第一通信设备为终端时，信道可以为PRDCH。
例如，在第二通信设备为终端、第一通信设备为网络节点时，信道可以为PDRCH。
可选地，控制信息可以显式指示信道的传输结束时刻，也可以隐式指示信道的传输结束时刻。对S102的详细说明，请参见下述各方式。
在本申请实施例中，基于控制信息，得到信道的传输结束时刻，可以实现根据控制信息得到信道的传输结束时刻的目的。
在相关技术中，信道的传输结束位置固定在一个时隙(slot)或者一个子帧内，使得信道的传输结束位置的灵活性差。而在本申请实施例中，根据控制信息得到信道的传输结束时刻，可以使得信道的传输结束位置在任意时刻，提高了信道的传输结束位置的灵活性。
在一种可能的实现方式中，控制信息中的控制信息用于指示下述一项或多项：

第二单元的个数，用于确定目标信息占用的时域资源长度，第二单元以预设码片数量或者预设符号数量为单位；
与信道的预设传输结束时刻的时域资源偏移量；

在本申请实施例中，目标信息为第一通信设备实际需要的数据信息，或者用于后续处理的数据信息。长度可变的信息是指占用的时域资源长度可以根据实际需求变化的信息。
可选地，信道承载的信息中还包括长度固定的信息。长度固定的信息是指占用的时域资源长度固定不变的信息。

可选地，本申请实施例中的时域资源长度还可以是以P个码片、或者P个OOK符号、或者P个OFDM符号为单位的时域资源长度。其中，P为大于和/或等于2的整数。
可选地，控制信息还可以用于指示下述一项或多项：编码类型，码率，调制类型。可选地，编码类型、码率、调制类型中的一项或多项还可以通过其他方式获得。
在一种可能的实现方式中，上述S102可以包括：
基于控制信息，得到目标信息占用的时域资源长度；
基于目标信息占用的时域资源长度，得到信道的传输结束时刻。
可选地，目标信息对应的比特数量为原始信息的比特数量，目标信息基于对原始信息进行编码和调制得到，原始信息与第一预设比特数量对应。
可选地，目标信息对应的比特数量为编码后信息的比特数量，目标信息基于对编码后信息进行调制得到，编码后信息与第二预设比特数量对应。
编码类型为进行编码所使用的编码类型。可选地，编码类型可以为曼彻斯特编码、米勒编码(miller)、或者FM0编码，其中，FM0编码的全称为双相间空号编码(Bi-Phase Space Coding)。
码率即为编码效率，是指编码后的数据中有用信息占全部信息的比例。
调制类型为进行调制所使用的类型。可选地，调制类型为二进制启闭键控(On-Off Keying，OOK)或者二进制相移键控(Binary Phase Shift Keying，BPSK)。OOK可以具体可以为OOK-1或者OOK-4等。

L1＝N1×R÷M
其中，L1表示目标信息占用的时域资源长度，N1表示原始信息的比特数量，R表示第一系数，M表示第二系数。
L1可以指示传输N1比特的原始信息所需要的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号数量。
M指示1个OFDM符号只传输M比特(bit)信息。
在本申请实施例中，在编码类型为曼彻斯特编码、且未指示码率时，R＝2。
