具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
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。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
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11和网络侧设备12。其中，终端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)、增强现实(augmented reality，AR)/虚拟现实(virtual reality，VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(Vehicle User Equipment，VUE)、行人终端(Pedestrian User Equipment，PUE)、智能家居(具有无线通信功能的家居设备，如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer，PC)、柜员机或者自助机等终端侧设备，可穿戴式设备包括：智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、智能服装等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以包括接入网设备或核心网设备，其中，接入网 设备也可以称为无线接入网设备、无线接入网(Radio Access Network,RAN)、无线接入网功能或无线接入网单元。接入网设备可以包括基站、无线局域网(Wireless Local Area Network，WLAN)接入点或WiFi节点等，基站可被称为节点B、演进节点B(eNB)、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)、家用B节点、家用演进型B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系统中的基站为例进行介绍，并不限定基站的具体类型。
相关技术中的BSC设备的功能方式可以是：完全无源(Passive)、半无源(Semi-passive)或有源(active)。
1)对于无源反向散射通信来说，BSC Tag首先从外界电磁波中获取能量(即进行能量收集(Energy harvesting))，并供给内部的信道编码与调制等电路模块工作，同时再反向散射射频信号进行通信，从而实现零功耗通信。
2)对于半无源BSC Tag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 Tag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。
3)对于有源BSC Tag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。
例如：如图2a所示的反向散射通信使用场景为：手机作为反向散射通信控制设备(即阅读器(Reader))，其与作为反向散射通信的终端设备(即Tag))的智能眼镜连接。Tag收集手机发送信号的能量或其他专用设备提供的能量，通过反射手机发送的信号x(t)来发送Tag的信息b(t)。
从反向散射通信的架构上，BCS又可以分成以下三类：
单基地反向散射通信系统(Monostatic Backscatter Communicaiton System，MBCS)；
双基地反向散射通信系统(Bistatic Backscatter Communicaiton Systems，BBCS)；
环境反向散射通信系统(Ambient Backscatter Communicaiton Systems，ABCS)。
其中，如图2b所示，在MBCS中包含BSC发送端(比如Tag)和读写器(Reader)。Reader中包含射频(Radio Frequency，RF)信号源(以下统一称之为RF射频源)和BSC接收端，其中RF射频源用于产生RF射频信号从而给BSC发送端/Tag供能。BSC发送端 通过反向散射经过调制后的RF射频信号，Reader中的BSC接收端接收到该反向散射信号后进行信号解调。由于RF射频源和BSC接收端是在同一个设备中，比如这里的Reader，因此称之为单站反向散射通信系统。
在MBCS系统中，由于从BSC发送端发送出去的RF射频信号会经过往返信号的信号衰减引起的双倍远近效应，因而信号的能量衰减大，因而MBCS系统一般用于短距离的反向散射通信，比如传统的RFID应用。
如图2c所示的BBCS中，RF射频源(例如：RF carrier emitter：射频载波发射器)和BSC接收端是分开的，BBCS避免了往返信号衰减大的问题，另外通过合理的放置RF射频源的位置可以进一步提高BBCS通信系统的性能。
值得注意的是，ABCS是与BBCS相似的架构，不同之处包括：BBCS系统中的射频源为专用的信号射频源，而ABCS系统中的射频源可以是可用的环境中的射频源，比如：电视塔、蜂窝基站、WiFi信号、蓝牙信号等。
在实施中，对于上述MBCS、BBCS和ABCS，其Reader可以是网络侧设备或终端，射频源可以是网络侧设备或终端，本申请实施例中主要提出了针对射频源是终端的反向散射通信系统中，如何使终端能够向BCS Tag供能的方法。
在实施中，反向散射通信蜂窝组网架构具体可以从射频源、上行数据传输、下行数据传输的不同分为如下表1所示的8种架构：
表1

例如：如上表1中的架构3-1b如图3a所示，射频源为UE，网络侧设备直接传输下行数据给BSC Tag；而上行传输中，BSC Tag先反向散射数据给UE，再由UE转发数据给网络侧设备。
再例如：如上表1中的架构3-2b如图3b所示，射频源为UE，下行数据由网络侧设备先下发给UE，再由UE转发给BSC Tag；上行传输中，BSC Tag直接反向传输信号给网络侧设备。
再例如：如上表1中的架构3-3b如图3c所示，射频源为UE，下行数据由网络侧设备先下发给UE，再由UE转发给BSC Tag；上行传输中，BSC Tag先反向散射数据给UE，再由UE转发数据给网络侧设备。
值得提出的是，在实施中，除了上述图3a至图3c所示的反向散射通信蜂窝组网架构之外，本申请提供的反向散射通信供能方法还可以应用于其他反向散射通信蜂窝组网架构，例如：假设网络侧设备和BSC Tag直接进行上行数据传输和下行数据传输，且由终端向BSC Tag提供用于发射上行数据的能源，即终端不进行BSC数据的转发，只是为BSC Tag提供能源。在此对应用本申请实施例提供的反向散射通信供能方法的反向散射通信蜂窝组网架构不作具体限定。
在UE辅助的组网架构下，传统UE、辅助(Helper)以及中继(Relay)等设备都可以作为终端来辅助组网。在UE辅助的反向散射通信中，UE可以支持给Tag供能。本申请实施例中，提出了如何在反向散射通信中建立终端供能方案，来支持BSC业务。
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供能方法、反向散射通信供能装置、通信设备、终端和网络侧设备等进行详细地说明。
请参阅图4，本申请实施例提供的一种反向散射通信供能方法，其执行主体可以是终端，例如：如图1中所列举的各种类型的终端，以及Helper、Relay等，在此不作具体限 定。如图4所示，该反向散射通信供能方法可以包括以下步骤：
步骤401、终端在获取到目标信息的情况下，根据所述目标信息向反向散射通信BSC设备发送目标射频信号或停止向所述BSC设备发送目标射频信号，其中，所述目标信息用于触发所述终端为所述BSC设备供能或停止供能，所述目标射频信号用于为所述BSC设备提供反向散射通信所需的能源。
在实施中，上述终端获取到目标信息可以是：终端从网络侧设备和BSC设备(例如：BSC Tag)中的至少一个接收到携带目标信息的信号(例如：在终端转发网络侧设备和BSC设备之间的数据时，终端从接收到的信号中解调出目标信号)，或者是终端监听到网络侧设备发出的寻呼消息中携带的目标信息，或者是终端监听到网络侧设备发送给BSC设备的信号中的目标信息，或者是终端监听到BSC设备发送给网络侧设备的信号中的目标信息。当然，在实施中，上述目标信息还可以是终端自身生成的信息。
作为一种可选的实施方式，所述目标信息为以下至少一项：
来自网络侧设备的第一指示信息，所述第一指示信息指示所述终端为所述BSC设备供能或停止供能；
来自所述BSC设备的第一请求信息，所述第一请求信息请求所述终端为所述BSC设备供能或停止供能；
来自所述终端的且用于建立或释放BSC链路的相关信息，其中，由所述终端发起建立或释放BSC链路。
选项一，终端可以接收或监听网络侧设备发出的第一指示信息，以通过第一指示信息来向终端指示目标信息。
可选地，所述第一指示信息携带于以下至少一项：
来自所述网络侧设备的寻呼消息(Paging Message)(例如：终端可以采用监听的方式获取来自所述网络侧设备的寻呼消息，该寻呼消息的短消息(Short Message)、寻呼原因(Paging Cause)和寻呼指示信息中的至少一项可以包括上述第一指示信息，如:寻呼原因为BSC数据转发(BSC data forwarding)或BSC MT(即BSC被叫))；
来自所述网络侧设备的配置信息(再例如：终端可以直接接收所述网络侧设备通过任意方式(例如：配置信息可以携带在下行控制信息(Download Control Information，DCI)、非接入层(Non-Access Stratum，NAS)信令、无线资源控制(Radio Resource Control，RRC)信令、媒体接入控制(Medium Access Control，MAC)层信令或物理层信令中，或者，配置信息与预设序列号(Sequence)关联，从而使终端获取预设序列号便可以确定关联的配 置信息)发送的配置信息，以配置终端按照第一指示信息进行供能或者停止供能)；
来自所述网络侧设备的且通过BSC链路传输的BSC命令；
所述网络侧设备发送给所述BSC设备的且被所述终端监听到的信息。
值得提出的是，在终端处于RRC连接态的情况下，终端可以通过接收来自所述网络侧设备的配置信息，来获取第一指示信息。在终端处于RRC空闲态或RRC去激活态的情况下，终端可以通过监听来自所述网络侧设备的寻呼消息，来获取第一指示信息。当然，终端在处于RRC连接态的情况下，也可以通过监听来自所述网络侧设备的寻呼消息，来获取第一指示信息，在此不作具体限定。
在实施中，若终端参与反向散射通信中的数据转发，则终端可以通过BSC链路直接接收网络侧设备发送的BSC命令。例如：在如图3b所示架构中，UE可以转发网络侧设备发送给BSC设备的信息，则网络侧设备可以通过BSC链路向BSC设备发送BSC命令(例如：控制BSC设备进行读取、写入等任意操作的命令)，这样，终端在转发该BSC命令时，可以视作接收到第一指示信息，从而向BSC设备发送目标射频信号。
此外，终端可以采用监听的方式获取网络侧设备发送给BSC设备的BSC命令，例如：如图3a所示架构中，UE虽然不会转发网络侧设备通过BSC链路向BSC设备发送BSC命令，但是，UE可以对网络侧设备发出的信号进行监听，从而获取该BSC命令。
可选地，在所述第一指示信息包括来自所述网络侧设备的且通过BSC链路传输的BSC命令的情况下，所述BSC命令用于以下至少一项：
命令所述终端和/或所述BSC设备建立BSC链路；
命令所述终端和/或所述BSC设备释放BSC链路；
命令所述终端和/或所述BSC设备开始BSC传输；
命令所述终端和/或所述BSC设备停止BSC传输；
命令所述BSC设备执行第二操作，所第二操作包括以下至少一项：选择(Select)、盘点(Inventory)、访问(Access)、质询(Challenge)、查询(Query)、读取(reading)、写入(writing)。
本实施方式中，终端可以基于网络侧设备命令终端和/或BSC设备执行：建立BSC链路、释放BSC链路、开始BSC传输、停止BSC传输，或者命令BSC设备执行第二操作的任意命令来作为目标信息，能够复用反向散射通信中的BSC命令来传输目标信息，从而解决单独传输目标信息时的资源消耗。其中，BSC传输可以包括：BSC命令和数据中至少一项的传输过程，例如：对BSC命令和数据的接收和/或发送操作。
上述第二操作可以是对BSC设备的任意操作，除了上述选择、盘点、访问、质询、查询、读取、写入之外，还可以包括：锁定或终止标签、与安全相关的操作(例如：认证标签)、与文件相关的操作(例如：打开标签用户内存中的特定文件)等，在此不作穷举。
当然，在实施中，除了上述BSC命令之外，上述第一指示信息还可以携带在所述网络侧设备发送给所述BSC设备的且被所述终端监听到的任意信息中，在此不作具体限定。
本实施方式中，终端获取第一指示信息后，可以按照网络侧设备的指示来开始向BSC设备供能或停止向BSC设备供能。
选项二，终端可以接收或监听BSC设备发出的第一请求信息。
可选地，所述第一请求信息携带于以下至少一项：
所述BSC设备发送给所述网络侧设备的信息；
所述BSC设备发送给所述终端的信息。
与上述选项一中终端采用监听或直接接收的方式获取第一指示信息相似的，终端也可以采用监听或直接接收的方式获取来自BSC设备的第一请求信息，例如：在如图3a所示架构中，UE可以将BSC设备发出的上行数据转发给网络侧设备，则UE可以接收并解调BSC设备发送的上行数据，以获取第一请求信息，在此不再赘述。
可选地，所述第一请求信息用于以下至少一项：
请求建立或释放BSC链路；
确认建立或释放BSC链路；
请求开始或停止BSC传输；
确认BSC传输的开始或停止；
请求所述终端向所述BSC设备供能或停止供能；
指示BSC的传输模式。
本实施方式中，BSC链路的建立或释放可以由BSC设备触发，例如：BSC设备为温度传感器上的BSC设备，当温度传感器检测到温度超标时，可以触发BSC链路的建立，从而向终端和/或网络侧设备发送请求建立BSC链路的请求信息。终端则可以接收或者监听到该请求信息，并基于该请求信息开始向BSC设备供能。
与之相对应的，在BSC设备请求释放BSC链路时，终端则也可以接收或者监听到该请求信息，并基于该请求信息停止向BSC设备供能。
当然，上述BSC链路的建立或释放也可以由终端或者网络侧设备触发，这样，在终端或者网络侧设备发起建立或释放BSC链路的过程后，BSC设备可以向终端或者网络侧 设备反馈建立或释放BSC链路的结果，例如：已成功建立BSC链路或者未完成建立BSC链路。终端则可以接收或者监听到该反馈结果，并在BSC设备确定建立BSC链路时，向该BSC设备供能。
与之相对应的，在BSC设备反馈释放BSC链路的结果时，终端则也可以接收或者监听到该反馈结果，并基于该反馈结果停止向BSC设备供能。
与上述请求建立或释放BSC链路的过程相似的，BSC设备也可以请求开始或停止BSC传输，或者请求所述终端向所述BSC设备供能或停止供能，终端在接收或监听到BSC设备请求BSC传输的开始或者请求所述终端向所述BSC设备供能的请求信息时，开始向BSC设备供能；终端在接收或监听到BSC设备请求BSC传输停止或者请求所述终端向所述BSC设备停止供能的请求信息时，停止向BSC设备供能。
与上述确认建立或释放BSC链路的过程相似的，BSC设备也可以向终端或网络侧设备反馈确认BSC传输的开始或停止的反馈结果，终端在接收或监听到BSC设备确认BSC传输的开始的反馈结果时，开始向BSC设备供能；终端在接收或监听到BSC设备确认BSC传输停止的反馈结果时，停止向BSC设备供能。
当然，在实施中，BSC设备还可以向终端和/或网络侧设备发送其他类型的信息，例如：指示BSC的传输模式的指示信息，从而使终端在接收或者监听到该指示信息时，按照该BSC的传输模式来确定向BSC设备供能的时间，例如：如图5所示的，在BSC设备进行数据传输的时间间隙中向BSC设备供能，以降低目标射频信号对BSC传输产生的干扰。
可选地，所述第一请求信息包括以下至少一项：
向所述BSC设备供能的请求或停止向所述BSC设备供能的请求；
所述BSC设备的能量状态指示；
用于控制所述BSC设备执行第二操作的命令的响应信息，所第二操作包括以下至少一项：选择、盘点、访问、质询、查询、读取、写入。
在实施中，上述第一请求信息可以是BSC设备主动发送的请求信息，例如：在需要发送BSC信号时，主动向终端和/或网络侧设备发送向所述BSC设备供能的请求，或者，在BSC设备电量较低时，主动向终端和/或网络侧设备发送能量状态指示(例如：电量百分比或剩余工作时长等)等，终端则可以接收或者监听到该第一请求信息，并根据请求开始向BSC设备供能。
当然，上述第一请求信息还可以是对BSC设备接收到的信息的响应信息，例如：对 用于控制所述BSC设备执行第二操作的命令的响应信息、答复(Reply)、查询确认(Query Acknowledgement，QueryACK)，该控制所述BSC设备执行第二操作的命令的响应信息与上述BSC命令用于BSC命令相对应，在此不作过多阐述。
本实施方式中，终端获取第一请求信息后，可以按照BSC设备的请求来开始向BSC设备供能或停止向BSC设备供能。
选项三，在由所述终端发起建立或释放BSC链路时，目标信息可以是来自所述终端的且用于建立或释放BSC链路的相关信息。
在实施中，终端可以基于BSC链路的建立而开始向参与该反向散射通信的BSC设备供能，或者，终端可以基于BSC链路的释放而停止向参与该反向散射通信的BSC设备供能，这样，在由所述终端发起建立或释放BSC链路时，终端可以自主触发向反向散射通信BSC设备发送目标射频信号或停止向所述BSC设备发送目标射频信号。
其中，终端获取到目标信息后，可以根据该目标信息，开始或者停止向BSC设备发送目标射频信号，该目标射频信号可以是连续波信号、电磁波信号等，在该目标射频信号覆盖BSC设备时，BSC设备能够从目标射频信号收集能源，从而获取可用于反向散射通信的能源。
可选地，所述目标信息包括以下至少一项：
指示开始供能的指示信息或指示停止供能的指示信息；
供能模式；
BSC的传输模式；
所述BSC设备的标识；
所述终端的标识。
选项1)，终端可以根据上述指示开始供能的指示信息开始发射目标射频信号，或者根据指示停止供能的指示信息停止发射目标射频信号。
选项2)，上述供能模式可以包括以下至少一项：连续供能指示或者间歇性供能指示，或者在一定时间段内连续地或间歇性地供能的指示，其还可以包括供能的周期、供能的开始时间、供能的停止时间、供能的时长、供能的功率等。在实施中，该供能模式可以根据反向散射通信的通信模式、通信时机、终端和BSC设备之间的相对位置、BSC设备和网络侧设备之间的相对位置等确定。这样，可以使终端发射的目标射频信号的时机与BSC设备需要发送BSC信号的时间以及所需能量更加匹配，从而使终端能够向提供BSC设备提供反向散射通信所需的能源的同时，还可以降低终端的能源浪费。
选项3)，上述BSC的传输模式可以包括以下至少一项：
传输的开始时间；
传输的持续时长；
间歇时长；
传输的周期。
其中，传输的持续时长可以是发送和/或接收数据的时长；间歇时长可以是不传输数据的时长，或者是为发送某一数据至接收该数据的响应消息之间的等待时长，或者是两次数据发送之间的等待时长。
在实施中，与上述供能模式相似的，根据该BSC的传输模式可以确定终端供能的开始时间、持续时长、周期等参数，其同样可以使终端发射的目标射频信号的时机与BSC设备需要发送BSC信号的时间更加匹配，从而降低了终端的能源浪费。
此外，上述BSC设备的标识和终端的标识，可以用于确定BSC设备和终端之间的相对位置关系，从而可以据此确定终端发送的目标射频信号的功率、空间朝向等参数中的至少一项，这样可以更加精确的控制终端发送的目标射频信号，使BSC设备位于目标射频信号的覆盖范围内，且能够基于目标射频信号获取足够的能源。
为了便于理解，以终端开始向BSC设备供能为例，针对不同的反向散射通信发起的场景，可以采用以下实施例来触发：
<场景一>
假设由网络侧设备发起BSC链路建立过程，则可以基于以下方式触发终端向BSC设备供能：
1)网络侧设备发送的第一指示信息，例如：网络侧设备寻呼终端开始向BSC设备供能；
2)网络侧设备发送的BSC命令，例如：终端在监听网络侧设备发送的BSC命令后，开始向BSC设备供能；
3)BSC设备发送的第一请求信息，例如：UE在监听Tag发送的第一请求信息后，开始供能。其中，BSC设备可以响应于接收到网络侧设备发送的BSC链路建立请求或命令，而向终端或网络侧设备发送第一请求信息。
<场景二>
假设由BSC设备发起BSC链路建立过程，则可以基于以下方式触发终端向BSC设备供能：

本实施方式中，终端可以在建立BSC链路或开始BSC传输后，持续的向BSC设备供能，一直到释放BSC链路或停止BSC传输时，停止向BSC设备供能。或者，在建立BSC链路之后，终端可以在BSC设备不传输数据的期间向BSC设备供能，这样，即使BSC设备在传输数据的间隙内获取反向散射通信所需的能源，例如：如图5所示，UE可以根据BSC设备与网络侧设备之间进行BSC的传输模式，确定在传输数据的间隙内向BSC设备供能。

向网络侧设备和/或所述BSC设备发送BSC链路建立请求；

在实施中，在由终端建立或释放BSC链路的情况下，终端可以基于建立或释放BSC链路的过程中的相关操作来触发向BSC设备供能，例如：在终端建立或释放BSC链路时，若未建立BSC链路，则终端可以向网络侧设备和/或所述BSC设备发送BSC链路建立请求，并基于发送该BSC链路建立请求而触发向BSC设备供能。再例如：在终端在已有的BSC链路上建立或释放BSC链路时，终端直接开始与所述BSC设备传输数据，并向BSC设备供能。
再例如：在终端处于RRC空闲态或RRC去激活态的情况下，终端可以在建立BSC链路之前，先向网络侧设备发送RRC连接建立请求消息，并基于发起的RRC连接建立过程而触发向BSC设备供能。
当然，在实施中，终端也可能在发起RRC连接建立过程，从而进入RRC连接态之后，再向网络侧设备和/或所述BSC设备发送BSC链路建立请求，并基于该BSC链路建立请求而开始向BSC设备供能，或者在终端向网络侧设备和/或所述BSC设备发送BSC链路建立请求，从而建立终端分别与网络侧设备和/或所述BSC设备之间的BSC链路之后，再基于该BSC链路开始与所述BSC设备传输数据时，终端基于开始与所述BSC设备传输数据而开始向BSC设备供能，在此不作具体限定。
在实施中，上述反向散射通信可以包括：所述网络侧设备、所述BSC设备和所述终端之间的通信。例如：如图3a至3c所示的，终端负责转发网络侧设备发送给BSC设备的BSC下行数据，和/或，终端负责转发BSC设备发送给网络侧设备的BSC上行数据。

其中，第一信息可以是BSC下行数据，第二信息可以是BSC上行数据。
值得注意的是，在实施中，终端也可能不负责转发BSC下行数据和BSC上行数据，而只是负责向BSC设备供能，在此不构成具体限定。
