  • Symbiotic scattering communication has the characteristics of mutual sharing in spectrum and energy domains, which can effectively solve the spectrum and energy consumption problems faced in communication. Its basic principle is that there are two types of systems in the system: the main system and the secondary system, where the main system is a traditional communication system containing an active transmission unit, and the secondary system uses the radio frequency signal of the main system to achieve low-power backscattering transmission, thereby sharing the spectrum, energy and basic equipment resources of the main system. While the secondary system obtains the opportunity for low-energy transmission, the performance of the main system is also expected to be improved due to the multipath components received from the secondary system.

为了便于理解本申请实施例，首先说明以下内容。
反向散射通信(Backscatter Communication，BSC)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，是一种比较典型的无源物联设备。反向散射通信发送端的基本构成模块及主要功能包括：
-天线单元：用于接收射频信号、控制命令，同时用于发送调制的反向散射信号。
-能量采集模块或供能模块：该模块用于反向散射通信设备进行射频能量采集，或者其它能量采集，包括但不限于太阳能、动能、机械能、热能等。另外除了包括能量采集模块，也可能包括电池供能模块，此时反向散射通信设备为半无源设备。能量采集模块或供能模块给设备中的其它所有模块进行供电。
-微控制器：包括控制基带信号处理、储能或数据调度状态、开关切换、系统同步等。
-信号接收模块：用于解调反向散射通信接收端或是其它网络节点发送的控制命令或数据等。
-信道编码和调制模块：在控制器的控制下进行信道编码和信号调制，并通过选择开 关在控制器的控制下通过选择不同的负载阻抗来实现调制。
-存储器或传感模块：用于存储设备的标识(ID)信息、位置信息或是传感数据等。
除了上述典型的构成模块之外，未来的反向散射通信发送端还可以集成隧道二极管放大器模块、低噪声放大器模块等，用于提升发送端的接收灵敏度和发送功率。
可选的，反向散射通信接收端即阅读器的基本构成模块及主要功能包括：
-天线单元：用于接收调制的反向散射信号。
-反向散射信号检波模块：用于对反向散射通信发送端发送的反向散射信号进行检波，包括但不限于幅移键控(Amplitude Shift Keying，ASK)检波、相移键控(Phase-Shift Keying，PSK)检波、频移键控(Frequency-Shift Keying，FSK)检波或正交振幅调制(Quadrature Amplitude Modulation，QAM)检波等。
-解调和解码模块：对检波出的信号进行解调制和解码，以恢复出原始信息流。
反向散射通信设备通过调节其内部阻抗来控制调制电路的反射系数Γ，从而改变入射信号的幅度、频率、相位等，实现信号的调制。其中信号的反射系数可表征为：
其中，Z0为天线特性阻抗，Z1是负载阻抗，j表示复数，θT表示相位。假设入射信号为Sin(t)，则输出信号为因此，通过合理的控制反射系数可实现对应的幅度调制、频率调制或相位调制。基于此，反向散射通信设备，可以是传统射频识别标识(Radio Frequency Identification，RFID)中的Tag，或者是无源或半无源物联网(Passive/Semi-passive Internet of Things，IoT)。为了方便，这里统称为BSC设备。
图1A示出了本申请中的一种单基地反向散射通信系统(Monostatic Backscatter Communication System，MBCSs)的示意图。MBCS系统包括BSC发送设备(比如标签Tag)和读写器Reader，读写器Reader中包含RF射频源和BSC接收设备，RF射频源用于产生RF射频信号从而来给BSC发送设备/Tag供能。BSC发送设备反向散射经过调制后的RF射频信号，Reader中的BSC接收设备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接收设备是在同一个设备中，比如这里的Reader，因此成为单站反向散射通信系统。MBCS系统中，由于从BSC发送设备发送出去的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。
图1B示出了本申请中的一种双基地反向散射通信系统(Bistatic Backscatter Communication Systems，BBCSs)的示意图。不同于单基地反向散射通信系统(Monostatic Backscatter Communication System，MBCSs)，BBCS系统中的RF射频源、BSC发送设备和BSC接收设备是分开的，故可以避免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，环境反向散射通信系统ABCSs也是双基地反向散射通信系统的一种，但与BBCS系统中的射频源为专用的信号射频源不同，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。
共生散射通信具有频谱和能量域的互惠共享特性，可以有效的解决通信中面临的频谱与能耗问题。其基本原理是，系统中存在两类系统：主系统和次系统，其中，主系统是一个包含主动式发送单元的传统通信系统，而次系统利用主系统的射频信号实现低功耗反向散射传输，进而共享主系统的频谱、能量以及基础设备资源等。在次系统获得低能耗传输机会的同时，主系统由于收到来自次系统的多径分量，其性能也有望得到提升。与传统的认知无线电技术相比，共生散射通信中的主次系统有望形成互惠关系，而非干扰关系，因而可以大幅提升系统的频谱资源利用效率。另外，不同于传统的反向散射通信(比如单基地反向散射通信、双基地反向通信以及环境反向散射通信)，共生散射通信中的主次系统相互合作，其接收机可采用联合检测以同时恢复主次系统发送的信号，进而实现高可靠的反向散射通信传输。
共生散射通信的系统模型可以分为两类：分离式模型和集成式模型。在分离式模型中，如图2A所示，主次系统分别有各自的接收机，其中主系统发送机(primary transmitter，PTx)传输信息给主系统接收机(primary receiver，PRx)；而次系统发送机(secondary transmitter，STx)采用空中调制技术发送信息给次系统接收机(secondary receiver，SRx)。在集成式模型中，如图2B所示，主次系统共享同一集成接收机(integrated receiver，IRx)，该接收机IRx需要同时恢复来自于主系统发送机PTx和次系统发送机STx的发送信号。由于集成式模型部署优势更大，因此本申请主要以集成式模型为基础进行说明。
以集成式模型为例，下面简单描述一下该系统的信号模型与原理。将PTx的发送符号周期记作Ts，其星座点集合记为如图3所示，次系统发送符号周期设为Ts的K倍，即Tc＝KTs。假设主次系统严格同步，次系统的一个符号对应主系统的K个符号。考虑次系统的第n个符号，令sl(n),l＝0,…,K-1表示主系统发送的第l个符号，则STx收到的来自主系统的信号为：
其中，p表示PTx的发送功率，h1和τ1分别表示从PTx到STx的前向链路的信道和传输时延，f0表示主系统的载波频率。
令h0表示从PTx到IRx的直接链路信道，h2表示从STx到IRx的后向链路信道。假设从PTx到IRx的直接链路与从PTx到STx再到IRx的反射链路具有相同的时延，则IRx收到的基带信号yl(n)可表示为：
其中，表示加性高斯白噪声。表示来自于直接链路的接收信号，表示来自于反射链路的接收信号，其中b(n)是STx的基带信号，或称为反向散射基带信号。由于反向散射链路接收信号中的b(n)与sl(n)的相乘关系，上述 信道被称为乘性多址信道，或是级联信道。
对于上述的系统，其主次系统的可达速率的上下界分别如下所示。当主系统符号sl(n)被完美解调时，次系统可获得其可达速率上界。当K取较大值，该上界可表示为：
而对于主系统来说，由于sl(n)存在于直接链路和反射链路中，在解码sl(n)时，反射链路对于直接链路来说可以看作为一个慢变的多径信道，为主系统传输带来多径效应，此时主系统的可达速率上界可表示为：
此可达速率上界在b(n)可以被完美解调时可达。此时，主系统获得性能增益，主次系统形成互惠共生关系。接收机可以采用联合检测接收机、半盲检测接收机以及全盲检测接收机等多种方式来解调b(n)，具体算法在此不再描述。
在共生反向通信等需要射频供能的系统中(以共生反向散射通信为例)，由于反向散射通信设备需要依赖于其它设备的射频信号供能才能进行数据传输，并且受到反向散射通信设备接收灵敏度的影响，反向散射通信设备的接收供能信号的灵敏度约为-20dBm～-30dBm，而接收通信数据的灵敏度约为-50dBm～-60dBm，因此射频供能成为制约反向散射通信传输距离的瓶颈。由于上下行传输信号衰减与节点间的距离相关，以下行为例，距离基站等供能设备更近的反向散射通信设备将收割到更多的能量的同时，需要更少的功率来满足上行传输需求；相反，距离基站较远的反向散射通信设备收割到更少能量的同时，需要更多的能量来满足上行传输需求，这个现象被称为双倍远近效应。基于能量波束赋形可以解决双倍远近效应问题，通过控制波束的宽窄和功率，使得较远的用户收割到更多的能量。
除了反向散射通信，一些不适用电池供电或者更换电池成本高的终端设备也可以基于射频能量进行供能。此类设备可以基于网络节点的无线射频能量进行能量收割与能量存储，并且利用收割到的能量自主生成载波信号来进行通信传输。
如图4所示，在基于波束传输的共生散射通信系统中，传统系统中的PTx与IRx基于波束传输来提高覆盖或降低干扰，而在PTx-STx-IRx组成的反向散射通信级联系统中，PTx通过采用定向波束来为反向散射通信设备供能和提供射频载波，从而提高反向散射通信设备的能量转化效率与远近效应问题，而IRx采用接收波束来提升STx-IRx的通信覆盖和降低干扰。进一步，基于波束传输的共生通信，一方面级联链路PTx-STx-Irx可以通过波束传输提供的波束增益，为直接链路PTx-IRx提供更大能量的多径增益，从而提高主系统的性能增益；另一方面，基于波束传输的直接链路PTx-IRx可以降低对级联链路PTx-STx-IRx的直接链路干扰影响，从而提高次系统的性能。对于PTx-IRx链路来说，一方面希望本链路的波束能够在稳定性和传输性能之间实现权衡，并且根据这个原则来进行波束选择；另一方面，则希望PTx-STx-IRx提供的多径分量越大，其自身获得多径增益越明显，因此希 望PTx-STx-IRx之间的通信能量越大越好，这也是PTx-STx-IRx在进行波束选择时需要考虑的因素之一。但对于PTx-STx-IRx来说，一方面希望PTx-IRx对其直接链路干扰越小越好，以减少对自身系统的干扰；另一方面，则希望本身的PTx-STx-IRx链路的波束能够在稳定和传输性能之间进行权衡，上述因素也是直接链路和反射链路在进行波束选择时需要考虑的另外的几个因素。
因此针对于PTx需要同时与IRx和STx两个设备进行发送波束(Tx beam)发送，而IRx需要同时与PTx与STx两个设备进行接收波束(Rx beam)接收，需要设计相应的波束训练/处理方法、信号质量评估准则以及对应的波束测量和波束上报等信令流程，以及相应的参数配置，使得最终训练出的PTx的两个Tx beam和IRx中的两个Rx beam整体是较优的，满足主系统和次系统的通信需求。
本申请方案可以应用在LTE系统、第5代(5th Generation，5G)NR系统以及NR演进系统，6G系统，以及IEEE 802.11、蓝牙系统、LoRa、Zigbee系统、无线光通信、无源物联网、反向散射通信等诸多适用于需要进行能量波束赋形的无线通信系统等，对此不作限定。
本申请实施例中，接收波束可表示为Rx beam，两者可以互换。发送波束可表示为Tx beam，两者可以互换。

下面结合具体实施例对本申请进行说明。
实施例一
在本实施例中，主要描述几种不同的波束测量报告的上报方式。与相关技术中的NR系统中的波束测量不同，本申请方案中的第一设备每次都能够收到直接链路和级联链路的Tx beam。并且，级联链路中的Tx/Rx beam与直接链路中的Tx/Rx beam在选择的时候原则可能存在差异，导致第一设备在第一Rx beam上测量第一信号的第一测量值与在第二Rx beam上测量第二信号的第二测量值时，第一测量值和第二测量值采用了不同的信号质量准则。上述因素都导致了第一设备上报波束测量报告，即第一设备不是控制/处理主体时都需要进行波束测量报告上报，需要设计新的波束测量报告格式来满足需求。
(一)独立上报
一种可行的方案为，不管第一设备是否在第一Rx beam上接收/测量第一信号与在第二Rx beam上接收/测量第二信号是否是同时，第三设备或第四设备给第一设备分别配置第一测量报告的上报资源与第二测量报告的上报资源。因此，第一设备在第一测量报告的时频资源上以及在第二测量报告的时频资源上，分别上报第一测量报告和第二测量报告。具体的，第一测量报告和第二测量报告的方式可以采用与相关技术中的NR系统相同的上报方式。针对多面板的MTRP/TRP的情况，可以采用与NR R15类型的两种上报形式，即：group based beam report和Non-group based beam report。
在Non-group based beam report形式中，第一设备在一个报告配置(ReportConfig)或上报资源中可上报N个最好的波束。在group based beam report中，第一设备在一个ReportConfig或上报资源中可上报M个第一设备能同时接收的波束。更进一步的，在group based beam report中，第三设备或第四设备配置了第一设备进行group based beam report时，会在ReportConfig或上报资源配置中配置一个与这个report关联的资源配置(resource  config)，比如resource setting，用于测量各个beam的测量值，然后第一设备从中选M个，并使用差分报告的方式报给第三设备或第四设备。对于其中波束选择与上报的情况，有两种方案：
-方案1：第一设备将M个同时接收的beam都上报给第三设备或第四设备。
-方案2：针对MPUE的情形，第一设备上报多个波束组(beam group)给第三设备或第四设备，每个beam group对应一个面板panel，每个beam group由能被该panel接收的beam所对应的参考信号标识组成。第三设备或第四设备从每个beam group中各选择一个Tx beam用于后续数据传输。
在Non group based beam report和group based beam report两种方案中，为了降低上报开销，当在1个上报实例中上报多个beam时，可以采用差分上报的形式。以测量值为L1-RSRP为例，波束测量的L1-RSRP值范围：-140dBm到-44dBm(7bits表示)，在所有测量值中最强的L1-RSRP用7bits表示(步长为1dB)，其余待上报的L1-RSRP值采用差分的方式，以4bits进行上报(步长为2dB)。
(二)组合上报
不同于独立上报中第三设备或第四设备给第一设备分别配置第一测量报告的上报资源与第二测量报告的上报资源，在组合上报中，第三设备或第四设备给第一测量报告和第二测量报告配置相同的上报资源，因此需要设计合适的组合方式来满足上报需求。具体的组合形式可以包含但不限于以下几种：
(a)按照测量报告分类
这种方式可延续相关技术中的NR系统的上报形式，不同之处只在于：在第一测量报告后面紧接着第二测量报告。而其中的第一测量报告和第二测量报告可以采用相关技术中的NR中的上报形式，采用相同的差分或非差分上报形式。如图8A所示，为基于测量报告分类之后上报的一个示例，其中第一测量报告中的第一测量值以L1-RSRP为信号评估准则并且采用非差分上报方式，第一测量报告中允许最多上报两个满足条件的最好波束，即第一信号标识#1和第一信号标识#3对应的波束，因此在第一测量报告中包含的内容为第一信号标识#1、第一信号标识#3、第一信号标识#1对应的L1-RSRP(即对应的波束)、第一信号标识#3对应的L1-RSRP(即对应的波束)。第二测量报告中的第二测量值以L1-SINR为信号评估准则并且采用非差分上报方式，第二测量报告中允许最多上报两个满足条件的最好波束，即第二信号标识#2和第二信号标识#5对应的波束，因此在第二测量报告中包含的内容为第二信号标识#2、第二信号标识#5、第二信号标识#2对应的L1-SINR(即对应的波束)、第二信号标识#5对应的L1-SINR(即对应的波束)。
(b)按照接收时间窗进行组合
由于第一设备是在不同的Rx beam的不同时间接收第一信号和第二信号，因此一种上报方式是按照满足条件的波束的接收时间来进行波束上报，第一测量值/第二测量值可以采用差分或非差分上报形式。如图8B所示，为基于第一设备接收时间窗组合上报的一个 示例，按照一定时间进行分段，不同的时间段内上报满足条件的波束测量值及信号标识等，其中第一信号的第一测量值以L1-RSRP作为波束信号质量评估准则，第二信号的第二测量值以L1-SINR作为波束信号质量评估准则。在时间窗1内，只有第二信号标识#2对应的信号质量满足上报条件；在时间窗2内，第二信号标识#5以及第一信号标识#1对应的信号质量满足各自上报条件；在时间窗3内，只有第一信号标识#3对应的信号质量满足上报条件，因此可以按照图8B所示的组合方式进行上报。
(c)按照接收Panel index进行组合
由于第一设备是在不同Panel的不同Rx beam上接收第一信号和第二信号，因此一种上报方式是按照满足条件的波束的接收Panel index来进行波束上报，第一测量值/第二测量值可以采用差分或非差分上报形式。如图8C所示，为基于第一设备在不同的Panel上接收测量值的组合上报的一个示例，按照不同的Panel index，在各自的Panel上上报满足条件的波束测量值及信号标识等，其中第一信号的第一测量值以L1-RSRP作为波束信号质量评估准则，第二信号的第二测量值以L1-SINR作为波束信号质量评估准则。在Panel#1上，只有第一信号标识#3对应的信号质量满足上报条件；在Panel#2上，第二信号标识#5以及第一信号标识#1对应的信号质量满足各自上报条件；在Panel 3上，只有第二信号标识#2对应的信号质量满足上报条件，因此可以按照图8C的组合方式进行上报。
(d)按照上报内容分类进行组合
此组合方式中，上报不区分时间窗、Panel以及链路，而是按照上报内容分类进行组合，其中测量值区域可以采用差分或非差分上报形式。如图8D所示，为基于上报内容分类组合上报的一个示例，按照各自评估准则，只有第一信号标识#1，第一信号标识#3，第二信号标识#2和第二信号标识#5对应的波束满足各自的上报条件，因此在信号标识区域中将这四个信号标识放在一起；其对应的L1-RSRP或L1-SINR放在接下来的测量值区域中，可以采用差分或非差分形式；其它内容区域可以放置PMI，RI等信息，如图8D所示。
实施例二
本实施例二中，说明第二设备生成第一信号的方式。
(一)第二设备自主生成第一信号
此方案适合于待供能的第二设备为具有自主生成载波的设备，比如无源或半无源的UE设备，该设备可以根据配置信息生成对应的第一信号。其中对应的第一信号生成和配置方式如下：
(1)第四设备配置第一设备的第一信号的参数，所述参数包括：
(a)时域相关参数；
(b)频域相关参数；
(c)调制方式；
(d)发送功率；
(e)序列生成方式。
(2)第三设备在不同的Tx beam发送第三信号。
比如，该第三信号只用于第二设备的射频供能。
(3)根据配置的第一信号的参数，UE生成第一信号，并发送多个第一信号。
比如，第一信号可以为SRS、新设计的L1信号、CSI-RS、PSSS、SSSS等。
比如，多个第一信号的时域资源不同，频域资源相同或不同，且多个第一信号的时频域资源属于同一资源集。
(二)第二设备基于反向散射信号生成第一信号
此方案适合于待供能的第二设备本身不具有自主生成载波的BSC设备，需要其它设备给它提供射频载波后进行反向散射传输，包括无源或半无源的BSC设备。其中对应的第一信号生成和配置方式如下：
(1)第四设备配置第二设备的第一信号的参数，所述参数包括：
(a)时域相关参数；
(b)频域相关参数；
(c)调制方式；
(d)发送功率；
(e)序列生成方式。
(2)第三设备在不同的Tx beam发送第三信号。
比如，该第三信号用于BSC设备的供能，同时为BSC设备提供射频载波。
(3)根据配置的第一信号的参数，第二设备基于第三信号生成第一信号，并发送多个第一信号。
比如，第一信号可以为SRS、新设计的L1信号、CSI-RS、PSSS、SSSS等。
比如，多个第一信号的时域资源不同，频域资源相同或不同，且多个第一信号的时频域资源属于同一资源集。
比如，第一信号为第二信号的反向散射信号。
(三)第二设备直接转发第一信号
此方案适合于待供能的第二设备本身不具有自主生成载波的BSC设备，需要其它设备给它提供射频载波后进行反向散射传输，包括无源或半无源的BSC设备。但不同于(二)中基于负载阻抗调制生成反向散射信号，此处直接对入射的第三信号按照固定的反射系数进行反射，或者进行全1调制，从而生成第一信号，因此第一信号为第三信号的直接转发信号。其中对应的第一信号生成方式和配置方法如下：
(1)第四设备配置第二设备的第一信号的参数，所述参数包括：反射系数。
(2)第三设备在不同的Tx beam发送多个第三信号。
比如，第三信号的部分功率即可用于第二设备的供能，本身也是参考信号。
比如，第三信号可以为SRS、新设计的L1信号、CSI-RS、PSSS、SSSS等。
比如，多个第三信号的时域资源不同，频域资源相同或不同，且多个第三信号的时频 域资源属于同一资源集。
(3)根据配置的反射系数，第二设备直接反射第三设备在不同的Tx beam发送的多个第三信号，即发送多个第一信号。
其中，反射的第一信号为第三设备发送的第三信号的反向散射信号，只是不经过任何调制，或者进行全1调制和资源映射。此时，第一信号即为第三信号。
实施例三
由于本申请方案适合于不同的网络部署场景，本实施例三以蜂窝系统中常用的四种网络部署进行说明。值得注意的是，除了蜂窝系统，本申请中方案同样适合于WiFi系统、蓝牙、LoRa、Zigbee等系统。由于核心思想类似，在此不再展开叙述。

(9)如果第二设备具备收发波束，则第三设备配置指示第二设备的一个或多个TCI状态，具体的配置指示方式如上所述，在此不再赘述。
(二)如图10所示，第一设备为基站，第三设备为UE，且第一设备实现资源分配、参数配置、波束处理/训练等。
在图10所示的架构中，第一设备是基站设备，第二设备为需要射频供能的UE或BSC设备，第三设备是Legacy UE设备，第一设备需要同时解调来自第三设备和第二设备的信息。在这种架构中，由于执行测量的主体是基站设备，因此相比于上述(一)的基站为PTx和UE为IRx中UE需要执行波束测量报告上报过程，本架构下没有上报流程。方案如下：
(1)第一设备根据第二设备发送给第一设备的第一信号的第一测量值，来确定第一设备的第一Rx beam以及第三设备的第一Tx beam的参数，同时根据第三设备发送给第一设备的第二信号的第二测量值，来确定第一设备的第二Rx beam以及第三设备的第二Tx beam的参数，并配置指示第三设备的TCI状态。

(c)基于第三设备发送的第三信号，第二设备对第三信号不进行任何调制而以配置的反射系数进行反射后，或进行全1调制后，生成第一信号。
其中，所述第一设备可给第三设备配置第三信号的信号参数。

(三)如图11A和图11B所示，第一设备为UE，第三设备为UE，由第一设备执行波束训练/处理(图11B所示)，或由第三设备执行波束训练/处理(图11A所示)。
在图11A和图11B所示的架构中，第三设备为Legacy UE设备，第二设备为需要射频供能的UE或BSC设备，第一设备为Legacy UE设备，并且由第一设备执行波束训练/处理(图11B所示)，或由第三设备执行波束训练/处理(图11A所示)。该架构适用于没有网络部署的情况，类似于sidelink中的Mode2(d)场景。在该场景中，第一设备和第三设备的Legacy UE都有可能成为主UE即执行主体，来实现资源分配、参数配置、调度等。总体来说，该场景适用于供能和数据收发都是由Legacy UE与待供能UE/BSC设备完成，部署灵活，且由于Legacy UE一般距离BSC设备更近，因此可以提供更高能量效率的射频能量与上下行覆盖。
具体的，对于主UE为第三设备的情况，本方案与上述(一)中方案基本相同，不同之处有：
(1)第三信号和第二信号的类型包含：
(a)SRS信号；
(b)新设计的L1信号
(c)sidelink中的PSSS/SSSS信号；
(d)CSI-RS信号。

(四)如图12所示，第一设备为UE，第三设备为UE，第四设备为不同于第一设备和第三设备的第三方设备，比如基站设备。
在图12所示的架构中，第三设备为Legacy UE设备，第二设备为需要射频供能的UE或BSC设备，第一设备为Legacy UE设备，并且第四设备为基站设备。该架构适用于没有网络部署以及有网络部署的情况，类似于sidelink中的Mode2和Mode1场景。在该场景中，第四设备即基站设备来实现资源分配、参数配置、调度、波束处理/训练等，从而减轻主UE的处理复杂度。但由于供能和数据收发都是由Legacy UE与待供能UE/BSC设备完成，部署灵活，且由于Legacy UE一般距离BSC设备更近，因此同样可以提供更高能量效率的射频能量与上下行覆盖。具体方案如下：
(1)第四设备根据第二设备发送给第一设备的第一信号的第一测量值，来确定第一设备的第一Rx beam以及第三设备的第一Tx beam的参数，同时根据第三设备发送给第一设备的第二信号的第二测量值，来确定第一设备的第二Rx beam以及第三设备的第二Tx beam的参数，并配置指示第一设备和第三设备的TCI状态。

(c)基于第三设备发送的第三信号，第二设备对第三信号不进行任何调制而以配置的反射系数进行反射后，或进行全1调制后，生成第一信号。
其中，所述第一设备可给第三设备配置第三信号的信号参数。
