本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。

图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端设备11、网络侧设备12和Backscatter通信设备13。其中，终端设备11也可以称作终端或者用户终端(User Equipment，UE)，终端设备11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop  Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(Ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端设备11的具体类型。网络侧设备12可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(Evolved Node B，eNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Network，WLAN)接入点、无线保真(Wireless Fidelity，WiFi)节点、发送接收点(Transmitting Receiving Point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。Backscatter通信设备13可以是指支持反向散射通信技术的通信设备，例如，Backscatter标签(Tag)或者Backscatter阅读器(Reader)等。
需要说明的是，本申请实施例的第一通信设备可以是支持Backscatter通信技术的终端设备11，第二通信设备可以是Backscatter通信设备13；或者本申请实施例的第二通信设备可以是支持Backscatter通信技的终端设备11，第一通信设备可以是Backscatter通信设备13。
为了便于理解，以下对本申请实施例涉及的相关内容进行说明：
一、反向散射通信(Backscatter Communication，BSC)
反向散射通信是指反向散射通信设备利用其它设备或者环境中的射频信号进行信号调制来传输自己信息。反向散射通信终端设备(BSC UE)，可以是传统射频识别(Radio Frequency Identification，RFID)中的标签(Tag)，或者是无源物联网终端(Passive Internet of Things，Passive-IoT)。
Backscatter(反向散射)技术作为一种无源或者低耗能技术，其技术特点在于可以通过改变接收到的环境射频信号的特性例如相位或幅度信息来完成 自身信号的传输，实现极低功耗或零功耗的信息传送。例如，如图2所示，反向散射发射器(Backscatter transmitter)通过阅读器(Reader)发射的射频信号或环境中的射频信号向阅读器传输信息。
从供能方式上来看，BSC UE可以分为完全无源(Passive)、半无源(Semi-passive)和有源(Active)三种方式。
对于无源BSC UE来说，BSC UE首先从外界电磁波中获取能量(Energy harvesting)，并供给内部的信道编码与调制等电路模块工作，同时在反射散射射频信号进行通信，从而实现零功耗通信。
对于半无源BSC UE来说，其内部电路模块是通过其自身的电池供电，并反向散射射频信号进行通信。由于其内部电池只用于简单的信道编码与调制等内部电路模块工作，功耗很低，因此BSC UE的电池寿命可以达到十年以上。外部来的射频信号全部都可以用于反向通信，而不用存储部分能量来进行供电。
对于有源BSC UE来说，其内置的电池不仅用于信道编码与调制等简单的内部电路工作，也可以用于功率放大(Power Amplifier，PA)和低噪声放大(Low Noise Amplifier，LNA)等电路工作，因而可以实现更复杂的反向散射通信的信号调制与解调。
示例地，如图3示出了一种Backscatter使用场景，即手机作为Backscatter控制设备(Reader)与作为Backscatter终端设备(Tag)的智能眼镜连接的场景，智能眼镜收集手机发送信号的能量，并通过反射手机发送的信号x(t)来发送Tag的信息b(t)。
二、设备内共存(In-device Coexistence，IDC)
同一设备可以同时支持新空口(New Radio，NR)/长期演进(Long Term Evolution，LTE)，以及全球卫星导航系统(Global Navigation SatelliteSystem，GNSS)(例如，全球导航系统(Global Positioning System，GPS)、全球卫星导航系统(Global Navigation Sateliite System，GLONASS)、北斗卫星导航系统(BeiDou Navigation Satellite System，BDS)、伽利略卫星导航系统(Galileo Satellite Navigation System，GALILEO)或印度星座导航系统(Navigation with Indian Constellation，NAVIC)、局域网(Wireless Local Area Network，WLAN) 和蓝牙(bluetooth)等功能。
其中，设备内共存问题可以是指设备内多个子帧或时隙等上的干扰问题。目前，NR/LTE UE已经支持与其他技术如GNSS、局域网和蓝牙等的IDC方案，例如，频分复用(Frequency Division Multiplexing，FDM)方案。
可选地，UE可以按照网络的指示上报IDC辅助信息，该IDC辅助信息可以包含正在受影响或可能受影响的频点，和受影响系统类型(Victim System Type)。
其中，上述受影响系统类型可以用于指示配置上行链路(Up Link，UL)载波集合(Carrier Aggregation，CA)时NR引起IDC干扰的受影响系统类型列表。值gps、glonass、bds、galileo和navIC表示GNSS的类型。值wlan表示WLAN，值bluetooth表示蓝牙。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的反向散射通信方法进行详细地说明。
请参见图4，图4是本申请实施例提供的一种反向散射通信方法的流程图，该方法可以由第一通信设备执行，如图4所示，包括以下步骤：
步骤401、第一通信设备向第二通信设备发送Backscatter配置信息或者在满足第一条件的情况下不执行第一Backscatter操作；
其中，所述第二通信设备用于利用与所述第二通信设备不同的设备发射的射频信号或者环境中的射频信号进行信号调制以传输信息，所述第一通信设备用于接收所述第二通信设备反射的射频信号以接收信息；
所述Backscatter配置信息为基于IDC问题确定的配置信息，所述第一Backscatter操作包括如下至少一项：与所述第二通信设备之间的数据收发；用于所述第二通信设备收集能量的载波发射。
需要说明的是，在一些场景下，上述第一通信设备也可以称为Backscatter阅读器(Reader)或Backscatter控制设备。上述第二通信设备也可以称为Backscatter标签(Tag)或无源IoT或Backscatter终端。此外，上述第一通信设备和第二通信设备中的至少一个除了支持Backscatter通信技术之外，同时还可以支持其他通信技术，例如，NR、LTE、蓝牙、WIFI、GNSS等。也即第一通信设备和第二通信设备中的至少一个设备内存在IDC问题。
上述Backscatter配置信息是基于IDC问题确定的配置信息，例如，可以理解为上述Backscatter配置信息可以是为了避免IDC问题确定的配置信息。其中，上述IDC问题也可以称为IDC干扰。可选地，上述Backscatter配置信息可以包括频分复用(Frequency Division Multiplexing，FDM)相关参数(例如，可用的频点、受影响的频点等)、时分复用(Time-Division Multiplexing，TDM)相关参数(例如，非连续发送(Discontinous Transmission，DTX)配置信息、非连续接收(Discontinuous Reception，DRX)配置信息等)等。
上述第一条件可以是与IDC问题相关的条件，例如，第一通信设备和第二通信设备中的至少一个设备存在IDC问题。
在一实施方式中，第一通信设备通过向第二通信设备发送基于IDC问题确定的Backscatter配置信息，以解决Backscatter通信技术与其他通信技术之间的IDC问题。以下结合举例对本实施方式进行说明：
示例一：在第一通信设备存在Backscatter通信技术与其他通信技术之间的IDC问题的情况下，第一通信设备向第二通信设备发送基于IDC问题确定的Backscatter配置信息。这样第一通信设备基于Backscatter配置信息进行Backscatter通信，可以减少Backscatter通信技术与其他通信技术之间的通信冲突或干扰。
例如，第一通信设备可以基于其他通信技术的配置信息向第二通信设备配置可用的频点、受影响的频点、可用的信道等。
示例二：在第二通信设备存在Backscatter通信技术与其他通信技术之间的IDC问题的情况下，第二通信设备可以基于IDC问题向第一通信设备上报Backscatter请求信息，第一通信设备可以基于该Backscatter请求信息向第二通信设备发送Backscatter配置信息。这样第一通信设备基于Backscatter配置信息进行Backscatter通信，可以减少Backscatter通信技术与其他通信技术之间的通信冲突或干扰。
例如，第二通信设备可以基于其他通信技术的配置信息上报受影响的频点、受影响的信道等，第一通信设备可以基于第二通信设备上报的受影响的频点、受影响的信道等，为第二通信设备配置可用的频点、可用的信道等。
示例三：在第一通信设备和第二通信设备均存在Backscatter通信技术与 其他通信技术之间的IDC问题的情况下，第二通信设备可以基于第二通信设备内的IDC问题向第一通信设备上报Backscatter请求信息，第一通信设备可以基于该Backscatter请求信息和第一通信设备内的IDC问题向第二通信设备发送Backscatter配置信息。这样第一通信设备基于Backscatter配置信息进行Backscatter通信，可以减少Backscatter通信技术与其他通信技术之间的通信冲突或干扰。
例如，第一通信设备存在Backscatter通信技术与第一通信技术之间的IDC问题，第二通信设备存在Backscatter通信技术与第第二通信技术之间的IDC问题，第二通信设备可以基于第二通信技术的配置信息上报受影响的频点、受影响的信道等，第一通信设备可以基于第二通信设备上报的受影响的频点、受影响的信道等，以及第一通信技术的配置信息，为第二通信设备配置可用的频点、可用的信道等。其中，上述第一通信技术和第二通信技术均可以是任意不同于Backscatter通信技术的通信技术。
在另一实施方式中，第一通信设备通过在满足第一条件的情况下不执行第一Backscatter操作，以解决Backscatter通信技术与其他通信技术之间的IDC问题。需要说明的是，上述不执行第一Backscatter操作可以理解为如下至少一项：不启动或者不开始第一Backscatter操作；在第一Backscatter操作处于执行过程中的情况下停止执行第一Backscatter操作。以下结合举例对本实施方式进行说明：
示例一：在第一通信设备存在Backscatter通信技术与其他通信技术之间的IDC问题的情况下，第一通信设备不执行第一Backscatter操作，这样可以避免Backscatter通信对其他通信技术的影响。
示例二：在第二通信设备存在Backscatter通信技术与其他通信技术之间的IDC问题的情况下，第二通信设备可以向第一通信设备发送指示信息，以指示第二通信设备存在IDC问题，第一通信设备基于指示信息不执行第一Backscatter操作，这样可以避免Backscatter通信对其他通信技术的影响。
本申请实施例提供的反向散射通信方法，第一通信设备向第二通信设备发送基于IDC问题确定的Backscatter配置信息，由于Backscatter配置信息考虑了IDC问题，因此基于Backscatter配置信息进行Backscatter通信可以减少 Backscatter通信技术与其他通信技术之间的通信冲突或干扰。此外，第一通信设备在满足第一条件的情况下不执行与所述第二通信设备之间的数据收发和用于所述第二通信设备收集能量的载波发射中的至少一项，也即通过不执行至少部分与Backscatter通信相关的操作的方式以减少Backscatter通信技术对其他通信技术的干扰。
