Description

异系统干扰避让方法、设备及系统
本申请要求于2020年6月30日提交国家知识产权局、申请号为202010607278.0、申请名称为“一种提供辅助信息的方法及UE”的中国专利申请的优先权，以及于2020年11月25日提交国家知识产权局、申请号为202011340572.6、申请名称为“异系统干扰避让方法、设备及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其是涉及一种异系统干扰避让方法、设备及系统。
背景技术
现有通信系统中，由于非授权频谱是开放性的，所有的通信系统都可以利用非授权频谱进行通信。其中，在5GHz频段，现有的通信系统可以包括侧行链路非授权(sidelink-unlicense，SL-U)系统、新空口非授权频谱(new radio-unlicense，NR-U)系统、授权频谱辅助接入(licensed assisted access，LAA)系统和无线保真(wireless fidelity，WiFi)系统等。
但是，由于多个通信系统都可以利用非授权频谱上进行通信，导致不同的通信系统之间因为信道占用问题，使得各个通信系统之间会存在异系统干扰。例如，在5GHz频段，对于SL-U系统，LAA系统由于产业问题站点部署较少，对SL-U系统的干扰较小，WiFi系统对SL-U系统的干扰较大，当WiFi系统长时间占用信道时，会导致SL-U系统无法正常运行。因此，如何改善非授权频谱上各个通信系统之间的异系统干扰成为亟待解决的问题。

具体实施方式
在描述本申请实施例之前，对本申请实施例涉及的技术术语进行描述。
非授权频谱：即开放性频谱，所有的通信系统都可以利用非授权频谱进行通信。
具体的，侧行链路非授权(sidelink-unlicense，SL-U)系统、新空口非授权频谱(new radio-unlicense，NR-U)系统、授权频谱辅助接入(licensed assisted access，LAA)系统、无线保真(wireless fidelity，WiFi)系统、蓝牙系统等通信系统都可以利用非授权频谱进行通信。
其中，LAA系统可以包括固定无线接入(fixed wireless access，FWA)系统、智能交通系统(intelligent transportation system，ITS)和无线局域网(radio local area network，RLAN)。
示例性的，LAA系统在5GHz频段占用非授权频谱可以如下述图1a至图1c所示。
如图1a所示，对于5100MHz～5350MHz频段，欧洲、以色列、俄罗斯、南非、土耳其、美国、加拿大、墨西哥、中国、日本、印度、新加坡和澳大利亚可以在5150MHz～5350MHz频段运行RLAN，巴西可以在5250MHz～5350MHz运行RLAN，韩国可以在5100MHz～5350MHz运行RLAN。
如图1b所示，对于5470MHz～5725MHz频段，欧洲、南非、土耳其、美国、巴西、日本和新加坡可以在5470MHz～5725MHz频段运行RLAN，加拿大、墨西哥和澳大利亚可以在5470MHz～5600MHz、5650MHz～5725MHz运行RLAN，韩国可以在5470MHz～5650MHz运行RLAN，俄罗斯可以在5650MHz～5725MHz运行RLAN。
如图1c所示，对于5725MHz～5925MHz频段，欧洲可以在5725MHz～5925MHz频段运行FWA系统，以及可以在5850MHz～5925MHz频段运行ITS系统，墨西哥和印度可以在5725MHz～5875MHz频段运行RLAN，美国、巴西、中国、新加坡可以在5725MHz～5850MHz频段运行RLAN，俄罗斯、韩国和加拿大可以在5725MHz～5825MHz频段运行RLAN。
其中，WiFi系统可以包括动态频率选择(dynamic frequency selection，DFS)、传输功率控制(transmit power control，TPC)、FWA、ITS、车间通信长期演进技术(long term evolution-vehicle，LTE-V)测试、无线电定位和卫星地球探测等。
示例性的，WiFi系统在5GHz频段占用非授权频谱可以如下述图1d所示，在2.4GHz频段占用信道可以如下述图1e所示。
如图1d所示，对于5150MHz～5350MHz频段，带宽可以为100MHz；对于5350MHz～5470MHz频段，带宽可以为120MHz；对于5470MHz～5725MHz频段，带宽可以为225MHz；对于5725MHz～5850MHz频段，带宽可以为125MHz；对于5850MHz～5925MHz频段，带宽可以为75MHz。
具体的，国际电信联盟(international telecommunication union，ITU)规定RLAN在5150MHz～5250MHz频段的功率为室内200mW；在5250MHz～5350MHz频段的功率为主导室内200mW；在5350MHz～5470MHz频段进行无线电定位和卫星地球探测；在5470MHz～5725MHz频段的功率为室内/室外1W。美国规定在5250MHz～5350MHz频段中，DFS/TPC的功率为50mW；在5350MHz～5470MHz频段进行无线电定位和卫星地球探测；在5470MHz～5725MHz频段，DFS/TPC的功率为250mW；在5725MHz～5850MHz频段的功率为800/1000mW；在5850MHz～5925MHz频段运行ITS。中国规定在5250MHz～5350MHz频段中，DFS/TPC的功率为200mW；在5350MHz～5470MHz频段进行无线电定位和卫星 地球探测；在5905MHz～5925MHz频段进行LTE-V测试。欧洲规定在5250MHz～5350MHz频段中，DFS/TPC的功率为200mW；在5350MHz～5470MHz频段进行无线电定位和卫星地球探测；在5470MHz～5725MHz频段中，DFS/TPC的功率为1W；在5725MHz～5795MHz频段，FWA的功率为20mW；在5795MHz～5875MHz频段运行ITS。
如图1e所示，对于2.4GHz频段，可以包括14个信道，每个信道包括20MHz的有效带宽，以及2MHz的强制隔离带宽，即每个信道的带宽为22MHz。例如，对于中心频率为2412MHz的1信道，其频率范围为2401MHz～2423MHz。由于2.4GHz频段的相邻信道相互重叠，相邻信道之间存在干扰，组网应用可以考虑非重叠信道。例如，中国、北美选择1、6、11信道作为非重叠信道，欧洲选择1、7、13信道作为非重叠信道。
由于多个通信系统都可以利用非授权频谱进行通信，导致不同的通信系统之间因为信道占用问题，使得各个通信系统之间会存在异系统干扰。例如，在5GHz频段，对于SL-U系统，LAA系统由于产业问题站点部署较少，对SL-U系统的干扰较小，WiFi系统对SL-U系统的干扰较大，当WiFi系统长时间占用信道时，会导致SL-U系统无法正常运行。因此，如何改善非授权频谱上各个通信系统之间的异系统干扰成为亟待解决的问题。
为解决该问题，本申请实施例提供了一种异系统干扰避让方法，该方法包括：第一设备广播包括时长指示信息的无线保真WiFi消息；其中，第一设备使用第一通信系统进行通信，第一通信系统为侧行链路非授权SL-U系统、新空口非授权频谱NR-U系统或者授权频谱辅助接入LAA系统；该时长指示信息用于指示第一时长，第一时长用于指示第二设备在第一时长内不占用第一信道，第一信道所在的频谱为非授权频谱，第二设备为通过WiFi系统进行通信的设备；第一设备通过第一通信系统向第三设备发送包括业务数据和/或控制信息的第一信息。本申请实施例中，第一设备通过向异系统的第二设备发送用于指示第二设备不占用第一信道的WiFi消息，可以使得第二设备在接收到WiFi消息后，不占用第一信道。第一设备通过在第二设备不占用第一信道时，向同系统的第三设备发送第一信息，可以降低异系统之间的干扰，提高同系统之间的通信可靠性。

步骤301、第一设备广播WiFi消息。
其中，WiFi消息可以包括时长指示信息，时长指示信息用于指示第一时长，第一时长用于指示第二设备在第一时长内不占用第一信道，第一信道所在的频谱为非授权频谱。
具体的，第一设备通过利用WiFi消息指示第二设备在第一时长内不占用第一信道，可以使得第二设备对该WiFi消息进行解析后，进入休眠状态，从而降低第二设备对信道的占用，提高第一通信系统的通信可靠性。
一种可能的设计中，第一设备在需要通过第一通信系统与第三设备进行通信时，广播WiFi消息。
示例性的，以第一设备需要通过第一通信系统向第三设备发送第一信息为例，第一设备可以在发送第一信息之前，广播WiFi消息，以指示第二设备不占用第一信道，并在第二设备不占用第一信道时，通过第一通信系统向第三设备发送第一信息，从而提高第一设备与第三设备之间的通信可靠性。
其中，第一信息可以包括业务数据和/或控制信息。
具体的，第一设备可以自行确定第一时长，也可以根据第一信息的传输时长确定第一时长，不予限制。
其中，第一时长可以大于等于第一信息的传输时长。
可选的，第一设备通过WiFi消息指示第二设备不占用非授权频谱对应的全部信道，即第一信道为非授权频谱对应的全部信道。
可选的，第一设备通过WiFi消息指示第二设备不占用非授权频谱对应的部分信道，即第一信道为非授权频谱对应的部分信道。
示例性的，当第一信道为非授权频谱对应的部分信道时，WiFi消息还可以包括第一信道的信道标识。
具体的，第一设备可以根据自身的通信需求确定第一设备与第三设备进行通信时需使用的第一信道，并将第一信道的信道标识携带在WiFi消息中，以使第二设备根据该信道标识确定第一信道，并在第一时长内不占用第一信道，降低第二设备对第一通信系统的异系统干扰，提高第一通信系统的通信可靠性。

其中，第一信道的信道标识可以为信道号、中心频率等用于指示第一信道的标识。
例如，以非授权频谱对应信道1、信道2和信道3为例，假设第一设备根据自身的通信需求确定第一设备与第三设备进行通信时需使用信道2或信道3，则第一设备可以将信道2和信道3的信道标识携带在WiFi消息中，以使第二设备根据WiFi消息不占用信道2和信道3，提高第一设备占用信道2或信道3与第三设备进行通信的成功率，从而提高第一通信系统的通信质量。
又一种可能的设计，第一设备为第一通信系统的主控设备，当第一通信系统的其余通信设备之间需要进行通信时，第一设备广播WiFi消息。
示例性的，以第一通信系统中包括第四设备和第五设备，且第四设备需要与第五设备进行通信为例，第四设备可以向第一设备发送用于指示第四设备需占用信道进行通信的指示信息，第一设备基于该指示信息广播WiFi消息，以指示第二设备不占用第一信道，从而提高第四设备抢占信道的成功率，提高第四设备与第五设备之间的通信可靠性。
其中，第一设备可以自行确定第一时长，也可以根据第四设备与第五设备的通信时长需求确定第一时长，不予限制。
具体的，以第四设备向第五设备发送第二信息为例，第四设备可以向第一设备指示第二信息的传输时长，以使第一设备根据第二信息的传输时长确定第一时长。第四设备也可以根据第二信息的传输时长确定第一时长，并将第一时长发送给第一设备，以使第一设备根据第一时长确定WiFi消息。其中，第一时长可以大于等于第二信息的传输时长。
可选的，第一设备通过WiFi消息指示第二设备不占用非授权频谱对应的全部信道，即第一信道为非授权频谱对应的全部信道。
可选的，第一设备通过WiFi消息指示第二设备不占用非授权频谱对应的部分信道，即第一信道为非授权频谱对应的部分信道。
示例性的，当第一信道为非授权频谱对应的部分信道时，WiFi消息还可以包括第一信 道的信道标识。
具体的，第一设备可以根据第四设备与第五设备进行通信的通信需求，确定第四设备与第五设备进行通信时需使用的第一信道，并将第一信道的信道标识携带在WiFi消息中，以使第二设备根据该信道标识确定第一信道，并在第一时长内不占用第一信道，降低第二设备对第一通信系统的异系统干扰，提高第一通信系统的通信可靠性。或者，第四设备也可以根据自身与第五设备进行通信的通信需求确定第四设备与第五设备进行通信时需使用的第一信道，并将第一信道的信道标识发送给第一设备，以使第一设备将第一信道的信道标识携带在WiFi消息中广播出去。
其中，通信需求可以为下述一种或多种：传输时延需求、信道环境需求、通信可靠性需求、业务数据类型等，不予限制。
其中，第一信道的信道标识可以为信道号、中心频率等用于指示第一信道的标识。
例如，以非授权频谱对应信道1、信道2和信道3为例，假设第一设备根据第四设备与第五设备进行通信的通信需求，确定第四设备与第五设备进行通信时需使用的第一信道为信道2或信道3，则第一设备可以将信道2和信道3的信道标识携带在WiFi消息中，以使第二设备根据WiFi消息不占用信道2和信道3，提高第四设备占用信道2或信道3与第五设备进行通信的成功率，从而提高第一通信系统的通信质量。
又例如，以非授权频谱对应信道1、信道2和信道3为例，假设第四设备根据第四设备与第五设备进行通信的通信需求，确定第四设备与第五设备进行通信时需使用的第一信道为信道2或信道3，则第四设备可以将信道2和信道3的信道标识发送给第一设备，以使第一设备将信道2和信道3的信道标识携带在WiFi消息中，从而使得第二设备根据WiFi消息不占用信道2和信道3，提高第四设备占用信道2或信道3与第五设备进行通信的成功率，从而提高第一通信系统的通信质量。
示例性的，WiFi消息的帧结构可以为图4所示的帧结构，其中，帧结构可以包括物理头和媒体接入控制(media access control，MAC)帧；物理头可以包括时长为8μs的传统短训练字段(legacy short training field，L-STF)、时长为8μs的传统长训练字段(legacy long training field，L-LTF)和时长为4μs的传统信号字段(legacy signal field，L-SIG)；MAC帧可以包括MAC帧头(MAC Header)字段、数据(data)字段和帧校验序列(frame check sequence，FCS)字段。
具体的，如图5所示，L-STF字段可以包括10个时长为0.8μs的字段；L-LTF字段可以包括2个时长为0.8μs的保护间隔(guard interval，GI)字段、时长为3.2μs的T1字段、以及时长为3.2μs的T2字段。L-SIG字段可以包括时长为0.8μs的GI字段和时长为3.2μs的信号(SIGNAL)字段。
其中，L-STF字段的前7个字段可以用于进行信号检测、自动增益控制(automatic gain control，AGC)、分集选择(diversity selection)，L-STF字段的后3个字段可以用于进行粗频偏估计定时同步(coarse frequency offset estimation timing synchronize)，便于WiFi系统同步。L-LTF字段可以用于进行信道和细频偏估计(channel and fine frequency offset estimation)，并承载便于接收设备解码的指示信息。L-SIG字段可以用于指示速率和长度。
示例性的，时长指示信息可以采用显示指示的方式指示第一时长。
例如，如图6所示，以WiFi消息包括时长为24μs的确认发送(clear to send，CTS)帧为例，CTS帧可以包括帧控制(frame control)字段、持续时间(duration/ID)字段、路由区域(routing area，RA)字段和FCS字段，其中，持续时间字段可以包括16比特，路由区域字段可以用于指示第一设备的MAC地址。第一设备可以通过持续时间字段指示第一时长。
具体的，第一设备在确定第一时长后，可以在持续时间字段的第0比特至第14比特中填写第一时长，并将第15比特置0，以使第二设备接收到WiFi消息后，根据持续时间字段中指示的第一时长，在第一时长内不占用信道。
需要说明的是，CTS帧中的持续时间字段可以用于指示0～32767μs，即第一设备可以将0～32767μs中的任一取值确定为第一时长。
又一种示例中，时长指示信息也可以采用隐式指示的方式指示第一时长。
例如，如图7所示，以WiFi消息仅包括20μs的物理头为例，第一设备可以通过L-SIG字段中的速率和长度指示第一时长。其中，如图8所示，L-SIG字段可以包括4比特的速率字段、12比特的长度字段和6比特的尾部(tail)字段，速率字段与数据传输使用的调制与编码方案(modulation and coding scheme，MCS)对应，长度字段用于指示WiFi消息的长度，第一时长＝长度/速率。
其中，速率可以为最低速率，如采用二进制相移键控(binary phase shift keying，BPSK)机制的1/2码率；长度可以为最大长度12比特。
例如，以速率为最小速率6Mbps，长度为12比特为例，第一设备可以通过物理头中的速率和长度指示第一时长为5.46ms。
需要说明的是，第一设备可以采用广播方式向第二设备发送WiFi消息，也可以采用单播或组播方式向第二设备发送WiFi消息，不予限制。
进一步的，如图9所示，第一设备在执行步骤301之前，还可以执行步骤301a。
步骤301a、第一设备判断测量得到的干扰功率是否满足预设阈值。如果是，则执行上述步骤301。
具体的，第一设备可以在广播WiFi消息之前，进行信道检测和/或空闲信道评估(clear channel assessment，CCA)，以测量干扰功率，并在干扰功率满足预设阈值时，以广播形式向第二设备发送WiFi消息，从而避免第一设备频繁地向第二设备发送WiFi消息，避免第二设备因频繁接收到WiFi消息而无法正常通信，提高第一通信系统的通信可靠性的同时，保证第二通信系统可以正常运行。
可选的，如图10所示，第一设备在向第二设备发送WiFi消息之前，执行先听后说(listen before talk，LBT)机制，通过进行信道检测和/或CCA，测量得到干扰功率。
可选的，预设阈值为预设干扰功率。
具体的，第一设备对干扰功率进行测量后，可以在干扰功率大于或等于预设干扰功率时，以广播形式向第二设备发送WiFi消息。
可替换的，预设阈值为预设干扰比例。
具体的，第一设备可以对干扰功率进行多次测量，并在干扰功率大于预设门限的次数与进行干扰功率测量的总次数的比值大于或等于预设干扰比例时，向第二设备发送WiFi消息。
例如，以第一设备进行干扰功率测量的总次数为10次，且预设干扰比例为0.6为例，假设干扰功率大于预设门限的次数为9次，则可以确定干扰功率大于预设门限的次数与进行干扰功率测量的总次数的比值为0.9，该比值大于0.6，则第一设备可以向第二设备发送WiFi消息。
需要说明的是，上述预设阈值与预设门限可以是通信协议预先规定的，也可以是网络设备预先配置的，不予限制。
一种可能的设计中，第一设备周期性测量干扰功率。
示例性的，第一设备可以基于第一设备自定义的周期测量干扰功率。
例如，第一设备进行干扰功率测量的周期可以为5ms、10ms、20ms等。
又一种示例中，第一设备也可以在预先配置的一段时间内进行干扰功率测量。
例如，第一设备可以在T＝{0ms、5ms、10ms、20ms、40ms、80ms、160ms、320ms}时进行干扰功率测量。
又一种可能的设计，第一设备非周期性测量干扰功率。
示例性的，第一设备可以在第一设备的通信性能较差时，进行干扰功率测量。
例如，第一设备可以在预设时间内无法抢占到信道时，进行干扰功率测量；或者第一设备可以在通信失败的次数超过预设失败次数时，进行干扰功率测量等，不予限制。
进一步的，当第一设备判断干扰功率满足预设阈值时，第一设备可以确定需要以广播形式向第二设备发送WiFi消息，并在第二预留时长后，以广播形式向第二设备发送WiFi消息。
其中，第二预留时长可以大于等于第二切换时延；第二切换时延为第一设备切换到以广播形式发送WiFi消息所需的时延。
示例性的，第二切换时延可以为第一设备调度用于以广播形式发送WiFi消息的资源对应的调度时延。
步骤302、第二设备根据WiFi消息不占用第一信道。
具体的，第二设备接收到第一设备发送的WiFi消息后，可以根据WiFi消息在第一时长内不占用第一信道。
其中，当第二设备没有占用信道时，第二设备可以基于WiFi消息停止抢占信道，或者，也可以描述为第二设备停止进行信道竞争。当第二设备已经占用了信道时，第二设备可以基于WiFi消息释放已占用的信道。从而提高第一通信系统的通信设备抢占信道的成功率，提高第一通信系统的通信可靠性。
示例性的，如图10所示，第二设备接收到第一设备发送的WiFi消息后，可以对WiFi消息进行解析，并根据解析后的WiFi消息，在第一时长内不占用第一信道，或者也可以描述为在第一时长内进入休眠状态。
步骤303、第一设备向第三设备发送第一信息。
其中，第一信息可以包括业务数据和/或控制信息。
具体的，当第一设备需要与第三设备进行通信时，第一设备可以以广播形式向第二设备发送WiFi消息，指示第二设备不占用第一信道，并在第二设备不占用第一信道时向第三设备发送第一信息，提高第一设备与第三设备之间的通信可靠性。
可选的，第一信息还用于指示第一设备广播WiFi消息。
具体的，以第一设备为第一通信系统的主控设备为例，当第一通信系统的第三设备需要与其余通信设备进行通信时，第一设备可以以广播形式向第二设备发送WiFi消息，以指示第二设备在第一时长内不占用第一信道，并向第三设备发送用于指示第一设备已广播WiFi消息的第一信息，使得第三设备在第二设备不占用第一信道时与其余通信设备进行通信，提高第三设备的通信可靠性。
可选的，第一信息还用于指示WiFi消息的时频资源。
其中，WiFi消息的时频资源可以用于指示WiFi消息对应的时域资源和频域资源。
具体的，由于WiFi消息实际上是由与第三设备位于同一通信系统的第一设备发送的，并不是第二设备发送的，第三设备在进行干扰功率测量时，可以根据WiFi消息的时频资源，确定WiFi消息对应的干扰功率，并从测量得到的初始干扰功率里边去除WiFi消息对应的干扰功率，提高第三设备确定的干扰功率的准确性。
示例性的，第一设备可以将第一信息承载在侧行链路控制(sidelink control information，SCI)信令、MAC控制单元(media access control control element，MAC CE)信令或无线资源控制(radio resource control，RRC)信令中发送给第三设备，不予限制。
可选的，第一设备执行上述步骤301时，在第一预留时长后，执行上述步骤303，即第一设备广播WiFi消息时，经过第一预留时长，向第三设备发送第一信息。
其中，第一预留时长可以大于或等于WiFi消息的传输时长与第一切换时延的和；第一切换时延为第一设备由广播WiFi消息切换到发送第一信息所需的时延。
具体的，第一切换时延可以为第一设备从广播WiFi消息切换到发送第一信息时进行资源调度的调度时延。
示例性的，当第一设备为基于负载的设备(load based equipment，LBE)时，第一预留时长可以等于WiFi消息的传输时长与第一切换时延的和。
其中，当第一设备处于LBE模式时，第一设备可以在向第二设备发送WiFi消息时，经过WiFi消息的传输时长和第一切换时延，向第三设备发送第一信息。
又一种示例中，当第一设备为基于帧的设备(frame based equipment，FBE)时，第一预留时长可以大于WiFi消息的传输时长与第一切换时延的和。
其中，当第一设备处于FBE模式时，第一设备可以基于预先设置的最小传输单元发送WiFi消息和第一信息。
具体的，当第一设备需要向第二设备发送WiFi消息时，第一设备可以基于最小传输单元向第二设备发送WiFi消息，并在经过WiFi消息的传输时长和第一切换时延后，基于下一个最小传输单元，向第三设备发送第一信息。
示例性的，如图11所示，以最小传输单元为T3为例，第一预留时长T＝T1+T2+T4；其中，T4＝[fix((T1+T2)/T3)+1]*T3-(T1+T2)；fix函数是取商函数，T1是WiFi消息的传输时长；T2是第一切换时延。
需要说明的是，上述第一切换时延可以为通信协议预先规定的，也可以为网络设备预先配置的，不予限制。
其中，第一切换时延可以在百微秒以内，可选的，第一切换时延为0。
基于上述图3所示的方法，第一设备通过向异系统的第二设备发送用于指示第二设备 不占用第一信道的WiFi消息，可以使得第二设备在接收到WiFi消息后，不占用第一信道。第一设备通过在第二设备不占用第一信道时向同系统的第三设备发送第一信息，可以降低异系统之间的干扰，提高同系统之间的通信可靠性。
基于上述图3，第三设备接收到第一设备发送的第一信息后，还可以执行图10所示的步骤304，提高第三设备确定干扰功率的准确性。
步骤304、第三设备根据第一信息，确定第三设备对应的干扰功率。
其中，第三设备对应的干扰功率为第三设备进行信道检测和/或空闲信道评估CCA时确定的初始干扰功率与WiFi消息对应的干扰功率的差值。
具体的，对于非透传通信场景，当第一设备采用广播形式发送WiFi消息时，第三设备也可以接收到WiFi消息，但是由于WiFi消息实际上是第一设备发送的，所以，第三设备在确定第三设备对应的干扰功率时，可以从测量得到的初始干扰功率中去除WiFi消息对应的干扰功率。
示例性的，如图12所示，第三设备可以根据第一信息确定WiFi消息的时频资源，根据WiFi消息的时频资源确定WiFi消息对应的干扰功率，将第三设备进行信道检测和/或空闲信道评估CCA时确定的初始干扰功率与WiFi消息对应的干扰功率的差值，确定为第三设备对应的干扰功率。
