基于上述实施例，进一步地，上述技术方案可以应用在多种应用场景中并采用不同的承载方式，本申请实施例给出了其中的几种具体的实施方式进行举例说明。
在一种实施方式中，如图5所示为有lagacy UE作为BSC UE中继传输的一种网络架构。在图5中，第一设备为gNB 501，第二设备和第四设备均是具有支持完整3GPP协议栈的Legacy UE，并且具有载波发生器，功率放大器等器件，标记为第二UE 502和第三UE 504，第三设备标记为BSC UE 503。BSC UE 503可以利用gNB发送给第三UE 504的第四信号S4进行反向散射传输。BSC UE 503可以直接以第一信号S1反向散射传输给gNB 501；也可以以第二信号S2先反向散射传输给第二UE 502，并以第二UE 502为中继生成第三信号S3，并发送给gNB 501。
在这种架构下，本申请实施例的技术方案如下：
A1.gNB 501和第二UE 502通过协作传输的方式分别向BSC UE 503发送第一指示信息L1与第二指示信息L2。
在一种实施方式中，第一指示信息L1和第二指示信息L2携带相同的且完整的指示信息。
gNB 501给第二UE 502发送第三指示信息L3，指示第二UE 502向BSC UE 503发送第二指示信息L2。
第一指示信息L1和第二指示信息L2中携带相同的指示信息。
所述第一指示信息L1和第二指示信息L2中至少携带BSC UE 503传输第一信号S1和/或第二信号S2的完整的信号传输参数的指示信息；
所述第一指示信息L1和第二指示信息L2中还可以携带指示信息标识符、资源指示信息、源设备ID信息、BSC UE ID信息、完整性标识等；其中，对于完整性标识，一种实施方式中，对于分集传输指示信息方式，用比特“1”表示该指示信息是完整的。
在另一种实施方式中，第一指示信息L1和第二指示信息L2携带组成完整指示信息中的部分的指示信息。
gNB 501给第二UE 502发送第三指示信息，指示第二UE 502向BSC UE 503发送第二指示信息。
第一指示信息L1和第二指示信息L2中携带不同的指示信息。
所述第一指示信息L1和第二指示信息L2中至少携带BSC UE 503传输 第一信号S1和/或第二信号S2的部分信号传输参数的指示信息，合并后可以完整的指示BSC UE 503的信号传输参数；
所述第一指示信息L1和第二指示信息L2还可以携带指示信息标识符、资源指示信息、源设备ID信息、BSC UE ID信息、完整性标识、分段指示符等；其中，对于完整性标识，在一种实施方式中，分流传输指示信息方式，用比特“0”表示该指示信息是不完整的，并结合分段指示符来对指示信息进行解析。
第一指示信息L1和第二指示信息L2可以通过不同的方式承载：
例如：第一指示信息L1通过DCI承载，第二指示信息L2通过SCI承载；
指示第二指示信息L2的第三指示信息L3也可以通过DCI承载。
A2.BSC UE 503解析第一指示信息L1和/或第二指示信息L2中的内容，具体包括：
根据接收到的第一指示信息L1和/或第二指示信息L2中的指示信息标识符，以确定该指示信息是用于指示BSC UE 503传输的调度指示信息，以减少BSC UE 503的检测复杂度。
根据接收到的第一指示信息L1和/或第二指示信息L2中的指示信息的完整性标识符确定是对第一指示信息L1和第二指示信息L2是进行联合处理还是分集处理。
若第一指示信息L1和第二指示信息L2中的完整性标识符表征为非完整，比如指示比特为“0”，则可以根据分段指示符来对接收到的指示信息进行联合处理。
A3.BSC UE 503根据第一指示信息L1和/或第二指示信息L2中得到的指示信息中指示的信号传输参数，以信号传输参数向gNB 501发送第一信号S1和/或向第二UE 502以信号传输参数发送第二信号S2。
其中，所述第一信号S1和第二信号S2都是基于第四信号S4调制后的反向散射信号。
第二UE 502基于第二信号S2生成第三信号S3，并发送给gNB 501。
第二UE 502解调解码BSC UE 503发送的第二信号，并将获取到的信号进行调制和编码生成第三信号S3，并发送给gNB 501；
或者，第二UE 502对BSC UE 503发送的第二信号S2只进行放大处理得到第三信号S3，并发送给gNB。
本方案实施例一中，指示信息是基于现有的Uu接口中的DCI或PC5接口中的SCI承载，并且可能是重新经过设计的新的格式(format)的DCI和SCI，需要对现有协议中的DCI和SCI进行扩展，但总体仍是基于现在的NR空口协议。
在另一种实施方式中，采用如图5所示的网络架构，但为了进一步降低BSC UE503检测指示信息的复杂度，采用全新设计的统一承载方式，即基于类似于wifi物理帧帧头的前导序列承载方式。具体方案如下：
本申请实施例的网络架构与上述实施方式基本相同，这里不再赘述。不同的地方在于，为了进一步降低BSC UE 503检测指示信息的复杂度，采用了全新设计的统一承载方式，即基于类似于wifi物理帧帧头的前导序列承载方式。本申请实施例的技术方案如下：
B1.gNB 501和第二UE 502通过协作传输的方式分别向BSC UE 503发送第一指示信息L1与第二指示信息L2。
步骤B1.与上述步骤A1基本相同，重复部分此处不再赘述。
与上述步骤A1不同的是，第一指示信息L1和第二指示信息L2通过相同的方式承载：
例如，第一指示信息L1和第二指示信息L2都是通过新设计的前导序列承载；
指示第二指示信息L2的第三指示信息L3可以通过DCI承载。
其中，所述前导序列举例如下：
其中，同步序列用于BSC UE 503和gNB 501或第二UE 502进行同步；指示信息标识符用来表示该前导序列是用于BSC UE 503调度的指示符；完整性标识符用来表示该前导序列所携带的指示信息是否是完整的；分段指示符用来表示该前导序列所携带的指示信息是第几段指示信息，比如可以将信号传输参数指示进行分段，并采用比特图(bitmap)的方式来指示，比如如果分段指示符是“1010”，则可以说明该前导序列所携带的指示信息是完整指示信息中的第1段和第3段指示信息；信号传输参数指示符用来指示BSC UE503反向散射传输的信号传输参数，可以按照需求进行分段；预留比特用来指示其它功能扩展；填充比特用来保证整个前导序列的长度是固定长度的。
B2.BSC UE 503解析第一指示信息L1和/或第二指示信息L2中的内容。
步骤B2与上述步骤A2基本相同，重复部分此处不再赘述。
B3.BSC UE 503根据第一指示信息L1和/或第二指示信息L2中得到的指示信息中指示的信号传输参数，以信号传输参数向gNB 501发送第一信号S1和/或向第二UE 502以信号传输参数发送第二信号。
步骤B3与上述步骤A3基本相同，重复部分此处不再赘述。
本申请实施例通过采用全新设计的统一的基于前导序列的承载方式来承载BSC UE 503的指示信息，不仅可以降低BSC UE 503检测指示信息的复杂度，即BSC UE 503不需要检测不同承载方式的指示信息，而只需要检测统一格式的前导序列既可；另一方面，新设计的前导序列中的同步序列降低了BSC UE 503对同步的要求，可实现异步接收。
在另一种实施方式中，如图6所示，为在没有gNB覆盖下的由UE锚节点自主进行资源分配的一种副链路(sidelink)网络架构，且由Legacy UE作为BSC UE中继传输。在图6中第一设备为第一UE 601，此UE为支持完整3GPP协议栈的Legacy UE，并且可以作为sidelink中其它UE的锚节点，即该UE锚节点可以自主给其它UE分配资源；第二设备和第三设备都是具有支持完整3GPP协议栈的Legacy UE，标记为第二UE 602和第三UE 604，第三设备标记为BSC UE 603。BSC UE 603利用第一UE 601发送给第三UE 604的副链路信号，即第四信号S4进行反向散射传输，BSC UE 603可以直接以第一信号S1反向散射传输给第一UE 601；也可以以第二信号S2先反向散射传输给第二UE 602，并以第二UE 602为中继生成第三信号S3，并发送给第一UE 601。
在该网络架构下，本申请实施例的技术方案与图5中的技术方案的不同之处在于第一指示信息L1、第二指示信息L2和第三指示信息L3都是通过SCI进行承载的，而不是通过DCI承载，其它地方都相同，此处不再赘述。
本申请实施例中，采用了完全没有基站参与的一种sidelink网络部署架构，适合于家居场景或个人体域网，且第一指示信息L1和第二指示信息L2是基于sidelink中的SCI承载。该SCI有可能是重新设计的新的格式(format)的两步式SCI(two-stage SCI)，需要对现有协议中的第二步(2st-stage)SCI类型进行扩展；或者第一指示信息L1和第二指示信息L2是重新设计的一步式SCI，即one-stage SCI，此处不做具体限定。
在另一种实施方式中，采用如图6所示的网络架构，且与上一个实施方式中的方案基本相似。不同之处在于第一指示信息L1和第二指示信息L2是经过重新设计的基于前导序列的承载方式，而不是通过SCI进行承载。具体的设计方法此处不再赘述。
本申请实施例中，采用完全没有基站参与的一种sidelink网络部署架构，适合于家居场景或个人体域网。且第一指示信息L1和第二指示信息L2是通过采用全新设计的统一的基于前导序列的承载方式来承载BSC UE 603的指示信息，不仅可以降低BSC UE 603检测指示信息的复杂度，即BSC UE 603不需要检测不同承载方式的指示信息，而只需要检测统一格式的前导序列既可；另一方面，新设计的前导序列中的同步序列降低了BSC UE 603对同步的要求，可实现异步接收。
由上述实施例的技术方案可知，本申请实施例通过在不同的网络架构中，采用不同的承载方式，从第一设备和第二设备接收第一指示信息和第二指示信息，并根据第一设备和第二设备的协作传输方式对第一指示信息和第二指示信息进行解析以得到进行反向散射传输的信号传输参数，从而使第三设备获取足够的分集增益或功率增益，以使第三设备能够更可靠得接收网络节点发送的指示信息，进而更好得实现反向散射传输。
