Description

无线通信方法及相应的通信设备 技术领域

背景技术
近年来，无人机(drone或aerial或UAV(unmanned aerial vehicle))获得了广泛使用，而诸如长期演进(LTE)网络的无线通信网络由于其良好的性能，可以用于支持无人机业务，例如在无人机飞行期间与无人机通信，或者支持地面控制器/人员与无人机通过无线网络通信。在这里，诸如无人机之类的能够在空中飞行且能够通过无线通信网络与基站通信的用户终端可以被称为飞行用户终端。
与陆地用户终端相比，飞行用户终端的运动速度往往更快，因此可能更频繁地在小区之间切换。此外，由于飞行用户终端在空中飞行，与陆地用户终端相比，飞行用户终端遇到的障碍更少，因此，飞行用户终端可以具备视距传输的通信条件。飞行用户终端的这些特点使得更远、更广范围内的小区可以检测到飞行用户终端。因此，这些小区会遭受来自飞行用户终端的干扰，以及飞行用户终端也会遭受来自这些小区的干扰。而现有技术中的干扰管理方式主要是针对陆地用户终端而言的，并不能有效地适用于飞行用户终端，因此，需要一种适用于飞行用户终端的干扰管理的方法。

具体实施方式
为了使得本公开的目的、技术方案和优点更为明显，下面将参照附图详细描述根据本公开的示例实施例。
首先，参照图1来描述可在其中应用本公开的实施例的无线通信系统。该无线通信系统可以是LTE系统，也可以是任何其他类型的无线通信系统，比如LTE-A系统或5G系统等。在下文中，以LTE系统为例来描述本公开的实施例，但应当认识到，以下描述也可以适用于其他类型的无线通信系统。
如图1所示，无线通信系统100可以包括第一基站(BS)110和飞行用户终端(UT)150，该第一基站110是飞行用户终端150的服务基站。该无线通信系统100还可以包括与第一基站110相邻的多个基站，比如第二基站120、第三基站130，并且与第一基站110相邻的这些基站可以通过X2接口与第一基站110通信。此外，该无线通信系统100还可以包括与第一基站110不相邻的多个基站，比如第四基站140。需要注意的是，虽然第四基站140不是与第一基站110相邻的基站，但第四基站140可以是与第二基站120、第三基站130相邻的基站，因此，第四基站140可以通过X2接口与第二基站120、第三基站130通信。飞行用户终端150可以是能够在空中飞行并且能够与第一基站110通信的飞行器(AV)，例如无人机(drone或UAV，比如基于3GPP规范Rel.15的无人机、或基于3GPP规范Rel.15的增强无人机)。这里，飞行用户终端也可以可互换地称为飞行用户设备、 空中用户终端、空中用户设备等。需要认识到，尽管在图1中示出了四个基站和一个飞行用户终端，但这只是示意性的，该无线通信系统还可以包括更多个或更少个基站，和/或更多个飞行用户终端。此外，该无线通信系统也可以包括一个或多个非飞行用户终端的用户设备或终端(未示出)，比如陆地用户设备或终端。
下面，参照图2A和图2B来描述根据本公开的一个实施例的无线通信方法200。图2A是根据本公开的一个实施例的无线通信方法200的流程图。图2B是根据本公开的一个实施例的无线通信方法200的另一流程图。如图2A所示，在步骤S202中，第一通信设备向第二通信设备发送第一信息，其中，该第一信息包括飞行用户终端的标识信息。该步骤中的第一信息可以是表明其为飞行用户终端的信息，而不是普通用户设备或终端的信息。这里，第一通信设备和第二通信设备例如可以分别是图1所示的第一基站110和第二基站120，以及飞行用户终端可以是图1所示的飞行用户终端150。
在该实施例中，飞行用户终端的标识信息可以包括能够唯一地标识飞行用户终端的信息，例如飞行用户终端的国际移动用户识别码(International Mobile Subscriber Identification，ISMI)，飞行用户终端的无线网络临时标识(Radio Network Temporary Identity，RNTI)，比如小区RNTI(Cell RNTI，C-RNTI)，或者飞行用户终端的来自核心网的唯一的UE标志的临时移动用户标识(Temporary Mobile Subscriber Identity，TMSI)、或者传统的IMSI和用户类型(比如地面用户或者飞行用户类型标识)的组合信息，或者传统的C-RNTI和用户类型的组合信息、或者传统的TMSI和用户类型的组合信息等。第一通信设备作为飞行用户终端的服务基站，可以获取飞行用户终端的标识信息。具体的获取方式可以采用常规方式，例如飞行用户终端的服务基站可以通过核心网获得飞行用户终端的标识信息，或者飞行用户终端初始接入服务基站后服务基站可以获得飞行用户终端的标识信息，或者飞行用户终端的服务基站可以通过飞行用户终端的报告获得飞行用户终端的标识信息。
在该实施例中，第一通信设备与第二通信设备可以预先协商或预先确定用于发送第一信息的数据格式，以便当第一通信设备以该数据格式发送第一信息且第二通信设备接收到以该数据格式发送的第一信息时，第二通信设备可以获知该第一信息是与飞行用户终端有关的信息而不是与普通用户设备或终端有关的信息。
通过本实施例，第一通信设备可以将飞行用户终端的标识信息发送至第二通信设备，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行检测、抑制、避免等干扰管理。例如，以上行干扰为例，第二通信设备在获知该飞行用户终端的标识信息后，第二通信设备可以检测该飞行用户终端的存在并采取某些操作以抑制来自该飞行用户终端的干扰。具体地，比如第二通信设备可以跟踪该飞行用户终端并预测该飞行用户终端的干扰水平以避免干扰，而且在必要时第二通信设备还可以发起与第一通信设备的合作以抑制干扰。
需要认识到，当第一通信设备作为多个飞行用户终端的服务基站时，第一通信设备向第二通信设备发送的第一信息可以包括其服务的多个飞行用户终端中的部分或全部飞行用户终端的标识信息。例如，第一通信设备可以获取其服务的多个飞行用户终端的标识信息，并且将该多个飞行用户终端中的部分或全部飞行用户终端的标识信息以列表的形式包括在第一信息中，然后发送给第二通信设备。
根据本实施例的一个示例，步骤S202中的第一信息还可以包括飞行用户终端的运动状态信息、飞行用户终端的位置状态信息、飞行用户终端的无线资源测量信息、飞行用户终端的配置信息、飞行用户终端的调度信息中的至少一个。飞行用户终端的运动状态信息例如可以包括飞行用户终端的飞行速度、飞行方向或飞行用户终端的飞行模式(比如GPS模式(比如使用GPS模块实现精准悬停的模式)、运动模式(比如通过视觉系统实现精确悬停的模式)、姿态模式(比如不使用GPS模块和视觉系统定位的模式)或手动模式(比如通过遥控器控制的模式)等)等。飞行用户终端的位置状态信息例如可以包 括飞行用户终端的飞行高度或飞行用户终端所处的经度和纬度等。飞行用户终端的无线资源测量信息例如可以包括飞行用户终端对无线资源进行测量所形成的报告，比如参考信号接收功率(Reference Signal Receiving Power，RSRP)测量报告等。飞行用户终端的配置信息例如可以包括信令的配置信息，比如信道探测参考信号(Sounding Reference Signal，SRS)的配置信息等。飞行用户终端的调度信息例如可以包括飞行用户终端的上行调度信息、飞行用户终端的下行调度信息、或其组合等，调度信息比如飞行用户终端所占用的时频资源的信息等。
在该示例中，第一通信设备将飞行用户终端标识信息以及运动状态信息、位置状态信息、无线资源测量信息、配置信息或调度信息中的至少一个发送给第二通信设备，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行更为准确地检测、抑制、避免等干扰管理。
例如，以上行干扰为例，第二通信设备在获知该飞行用户终端的标识信息、以及运动状态信息和/或状态位置信息后，第二通信设备可以预测该飞行用户终端施加的当前干扰水平或稍后的干扰水平。具体地，比如，第二通信设备可以根据飞行用户终端的飞行速度、飞行高度或飞行模式等预测该飞行用户终端是远离或靠近第二通信设备，从而对来自该飞行用户终端的干扰进行预测，以获知飞行用户终端施加的稍后的干扰水平。
又例如，以上行干扰为例，第二通信设备在获知该飞行用户终端的标识信息以及无线资源测量信息后，第二通信设备可以直接推断该飞行用户终端施加的干扰水平。具体地，比如第二通信设备可以根据该飞行用户终端的RSRP报告获知RSRP，然后可以根据RSRP与第二通信设备的下行发送功率推断该飞行用户终端的下行路径损耗，进而可以推断该飞行用户终端的上行路径损耗，最后可以根据该飞行用户终端的上行路径损耗确定该飞行用户终端施加的干扰水平。
又例如，以上行干扰为例，第二通信设备在获知该飞行用户终端的标识信息、以及配置信息和/或调度信息后，第二通信设备可以直接测量该飞行用户终端施加的干扰水平。具体地，比如第二通信设备可以根据该飞行用户终端的SRS配置或UL调度信息直接测量该飞行用户终端施加的干扰水平。
可以理解，当第一信息包括飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的多个信息时，上面所描述的根据一个或多个信息对上行干扰或下行干扰进行检测、抑制、避免等干扰管理的操作可以组合在一起使用。
根据上面的描述可知，当第一通信设备作为多个飞行用户终端的服务基站时，第一通信设备向第二通信设备发送的第一信息不仅可以包括其服务的多个飞行用户终端中的部分或全部飞行用户终端的标识信息，而且还可以包括部分或全部飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。此外，根据本实施例的一个示例，对于该部分或全部飞行用户终端中的每个飞行用户终端而言，被包括在第一信息中的信息可以不同。例如，第一信息可以包括某一飞行用户终端的标识信息及运动状态信息，而且还可以包括另一飞行用户终端的标识信息及配置信息。
下面以一个具体的示例再次对第一信息进行说明。下面的表1示出了第一信息的一种示例性格式。如表1所示，在第一信息中，飞行用户终端的标识信息可以是强制性的(Mandatory，简称为“M”)，飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息或调度信息可以是可选的(Optional，简称为“O”)。

此外，根据本实施例的一个示例，第一通信设备在发送第一信息之前，可以主动地选择第二通信设备。例如，在步骤S202之前，方法200还可以包括步骤S201’，如图2A所示。在步骤S201’中，第一通信设备从多个候选通信设备中选择第二通信设备，比如，多个候选通信设备可以是与第一通信设备相邻的多个通信设备。上文已经提到，第一通信设备可以是图1所示的第一基站110。返回参照图1，第一基站110的相邻基站即第二基站120、第三基站130可以为这里的多个候选通信设备。
在这种情形下，第一通信设备可以从多个候选通信设备中任意选择一个作为第二通信设备，比如选择第二基站120作为第二通信设备。或者，第一通信设备还可以根据飞行用户终端的无线资源测量信息，比如RSRP报告，从多个候选通信设备中选择遭受飞行用户终端的干扰较为严重的通信设备(比如第二基站120)作为第二通信设备。或者，第一通信设备还可以根据飞行用户终端的运动状态信息，比如飞行速度、飞行方向等，从多个候选通信设备中选择可能遭受飞行用户终端的干扰较为严重的通信设备(比如第二基站120)作为第二通信设备。
根据本实施例的另一示例，第一通信设备也可以被动地选择第二通信设备，然后将第一信息发送至第二通信设备。例如，第一通信设备可以将向其发送请求的通信设备作为第二通信设备。比如，在步骤S202之前，方法200还可以包括步骤S201”，如图2A所示。在步骤S201”中，第一通信设备接收第二通信设备发送的对第一信息的第一请求。进而，第一通信设备响应于在步骤S201”中接收到的第一请求而执行步骤S202。
在该示例中，步骤S201”中的第一请求可以是第二通信设备向第一通信设备请求其服务的部分或全部飞行用户终端的信息，比如标识信息、运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。例如，第二通信设备可以只向第一通信设 备请求其服务的全部飞行用户终端的标识信息，则响应于第二通信设备的请求，第一通信设备可以将其服务的全部飞行用户终端的标识信息包括在第一信息中，然后发送给第二通信设备。
又例如，第二通信设备可以向第一通信设备请求其服务的部分飞行用户终端(比如飞行高度相对较高的飞行用户终端)的标识信息和运动状态信息。进而，响应于第二通信设备的请求，第一通信设备可以将这部分飞行用户终端的标识信息和运动状态信息包括在第一信息中，然后发送给第二通信设备。
在该示例中，步骤S201”中的第一请求还可以是其他设备经由第二通信设备向第一通信设备请求其服务的部分或全部飞行用户终端的信息，比如标识信息、运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。例如，其他设备可以将向第一通信设备的请求信息发送给第二通信设备，第二通信设备在接收到该请求信息后，可以对请求信息进行处理，并将处理后的请求信息发送给第一通信设备。当然，第二通信设备也可以不对该请求信息进行处理，而是将该请求信息直接发送给第一通信设备。
此外，当第一通信设备接收到的第一请求只请求飞行用户终端的标识信息时，第一通信设备还可以在发送飞行用户终端的标识信息之后再接收第二通信设备发送的另一请求，该另一请求可以请求除了飞行用户终端的标识信息以外的、飞行用户终端的其他信息，比如对飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。可替换地，该另一请求还可以请求飞行用户终端的标识信息以及飞行用户终端的其他信息，比如对飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。
例如，根据本实施例的一个示例，在步骤S202之后，方法200还可以包括步骤S203，如图2B所示。在步骤S203中，第一通信设备接收第二通信设备发送的第二请求，其中，该第二请求包括对飞行用户终端的运动状态信息、飞行用户终端的位置状态信息、飞行用户终端的无线资源测量信息、飞行用户终端的配置信息、飞行用户终端 的调度信息中的至少一个的请求信息。进而，第一通信设备响应于在步骤S203中接收到的第二请求而向第二通信设备发送其请求的信息。
在该示例中，第二请求可以是对多个飞行用户终端中的部分飞行用户终端的标识信息以外的、其他信息的请求，比如对部分飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个的请求。
此外，为了使更远的不相邻的(或者没有通信接口的，例如X2接口)通信设备也可以获知第一信息，第一通信设备向第二通信设备发送第一信息时，可以指示第二通信设备将接收到的第一信息转发给其他通信设备。例如，根据本实施例的一个示例，在步骤S202时或之后，方法200还可以包括步骤S204，如图2B所示。在步骤S204中，第一通信设备向所述第二通信设备发送第二信息，其中，该第二信息包括对第一信息进行转发的信息。
在该示例中，对第一信息进行转发的信息可以包括对第一信息进行转发的次数。例如，对第一信息进行转发的次数可以为对第一信息进行跳转发送的跳数(Hopping Number)。也就是说，可以通过多跳的方式将第一信息转发给多个基站。上文已经提到，第一通信设备和第二通信设备可以分别是图1所示的第一基站110和第二基站120。返回参照图1，第一基站110可以将对第一信息进行跳转发送的跳数发送给第二基站120，则第二基站120接收到跳数之后，可以根据跳数判断是否满足转发条件，如果是，则转发第一信息。另外，当第二基站120接收到跳数后，根据跳数可能会判断出不满足转发条件，则第二基站120可以不转发第一信息，也可以通过其他方式将第一信息传递给其他基站。例如，当第二基站120接收到跳数后，第二基站120可以对接收到的跳数进行数学运算(即减一运算)以获得更新后的跳数，然后判断更新后的跳数是否非零，如果是，则可以判断第二基站120满足转发条件，否则，则可以判断第二基站120不满足转发条件。另外，在第二基站120满足转发条件时，第二基站120还可以将更新后的跳数和第一信息转发给下一个基站。需要注意的是，第二基站120并不会将第一信息转发回第一基站110。
在此，以第二基站120接收到的跳数为3为例进行说明。例如，第二基站120通过X2接口从第一基站110接收到跳数为3，由于第一信息已经被第一基站110向第二基站120转发了一次，因此，第二基站120可以对跳数进行减一运算并获得更新后的跳数2。由于更新后的跳数2非零，因此，第二基站120满足转发条件，进而第二基站120可以通过X2接口将第一信息及更新后的跳数2转发给第四基站140。第四基站140可以执行与第二基站120类似的操作，直到不满足转发条件，可以停止对第一信息的转发。需要注意的是，第二基站120并不会将第一信息转发回第一基站110。由此可见，通过多跳的方式，第一通信设备将第一信息转发到其相邻的基站以及更远的基站，使得更远的基站也可以获知第一通信设备服务的飞行用户终端的相关信息，以便进行干扰管理。
在该示例中，对第一信息进行转发的信息还可以包括第一信息可以被转发到的基站的集合信息。也就是说，可以将第一信息转发至基站集合中的一个或多个基站。上文已经提到，第一通信设备和第二通信设备可以分别是图1所示的第一基站110和第二基站120。返回参照图1，第一基站110可以确定第一信息被转发到的基站的集合信息例如可以为{第二基站120，第三基站130，第四基站140}，则第一基站110可以将基站的集合信息发送至基站集合中的、与第一基站110相邻的基站，比如第二基站120、第三基站130。由于基站集合中的、与第一基站110不相邻的基站，比如第四基站140，和第一基站110之间不能直接通信，因此第一基站110不能把第一信息发送给第四基站140。下面以第一基站110将第一信息发送给第二基站120为例进行说明。当第二基站120接收到基站的集合信息后，可以根据基站的集合信息判断是否满足转发条件，如果是，则转发第一信息。例如，第二基站120可以判断基站的集合信息中是否存在自己的相邻基站，比如是否存在第二基站120的相邻基站第四基站140，如果是，则可以将第一信息转发至基站集合中的第四基站140。另外，当第二基站120接收到基站的集合信息后，根据基站的集合信息可能会判断出不满足转发条件，则第二基站120可以不转发第一信息，也可以通过其 他方式将第一信息传递给其他基站。需要注意的是，第二基站120并不会将第一信息转发回第一基站110。
此外，第一基站110还可以更新基站的集合信息，并将更新后的基站的集合信息发送给下一个基站或多个基站。例如，由于第一信息已经被第一基站110转发至与第一基站110相邻的第二基站120，因此，第一基站110可以将第二基站120从基站的集合信息中删除，以获得更新后的基站的集合信息，比如{第三基站130，第四基站140}，然后将第一信息及更新后的基站的集合信息{第三基站130，第四基站140}转发给第二基站120。第二基站120可以执行与第一基站110类似的操作，直到更新后的基站的集合信息为空，可以停止对第一信息的转发。
又例如，在第一信息已经被第一基站110转发至与第一基站110相邻的第二基站120且也已经被第一基站110转发至与第一基站110相邻的第三基站130的情形下，第一基站110可以将第二基站120和第三基站130从基站的集合信息中删除，以获得更新后的基站的集合信息，比如{第四基站140}，然后将第一信息及更新后的基站的集合信息{第四基站140}转发给第二基站120和第三基站130。第二基站120和第三基站130都可以执行与第一基站110类似的操作，即将与其相邻的第四基站140从基站的集合信息中删除，然后将第一信息及空的基站集合信息转发给第四基站140，或者只将第一信息转发给第四基站140。第四基站140接收到第一信息后，不再转发第一信息。由此可见，通过这种方式，第一通信设备也可以将第一信息转发到其相邻的基站以及更远的基站，使得更远的基站也可以获知第一通信设备服务的飞行用户终端的相关信息，以便进行干扰管理。
上文已经结合图1所示的无线通信系统100描述了图2A和图2B所示的方法200。在上述描述中，也提到了方法200中的第一通信设备和第二通信设备可以是图1所示的无线通信系统100中的第一基站110和第二基站120。在这种情形下，第一通信设备和第二通信设备之间可以通过X2接口传输第一信息、第二信息、第一请求或第二请求。
然而，本公开不限于此。根据本实施例的另一示例，方法200中的第一通信设备可以为图1所示的无线通信系统100中的第一基站110，而第二通信设备可以为无线通信系统100中的核心网设备(未示出)，比如移动管理实体(Mobility Management Entity，MME)。在这种情形下，第一通信设备和MME之间可以通过S1接口传输第一信息、第二信息、第一请求或第二请求。而且，MME在接收到第一通信设备发送的第一信息、第二信息后可以将这些信息转发给其他基站，比如图1所示的无线通信系统100中的第二基站120。此外，MME在接收到其他基站，比如图1所示的无线通信系统100中的第二基站120，发送的第一请求、第二请求后还可以将这些请求转发给第一通信设备。
此外，根据本实施例的一个示例，第一通信设备可以周期性地向第二通信设备发送第一信息和/或第二信息。例如，在第一通信设备周期性地接收飞行用户终端的无线资源测量报告，比如RSRP报告后，相应地可以周期性地执行步骤S202和/或步骤S204。
根据本实施例的另一示例，第一通信设备可以非周期性地向第二通信设备发送第一信息和/或第二信息。例如，第一通信设备可以根据无线通信系统的网络状态来确定何时向第二通信设备发送第一信息和/或第二信息。比如，在无线通信系统的网络状态较差时，可以为飞行用户终端设定最小需要测量的小区数目，以触发飞行用户终端向第一通信设备报告无线资源测量的结果，使得小区测量完成后飞行用户终端向第一通信设备报告。在此情形下，第一通信设备接收到飞行用户终端的无线资源测量报告后可以执行步骤S202和/或步骤S204。
通过上述实施例，第一通信设备可以将飞行用户终端的有关信息发送至第二通信设备，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行检测、抑制、避免等干扰管理。
下面，参照图3来描述根据本公开一个实施例的执行图2A和图2B所示的方法200的第一通信设备300。图3示出了根据本公开的一个实施例的第一通信设备300的结构示意图。由于第一通信设备 300的功能与在上文中参照图2A和图2B描述的方法的细节相同，因此在这里为了简单起见，省略对相同内容的详细描述。
如图3所示，第一通信设备300包括发送单元310，其被配置为向第二通信设备发送第一信息，其中，第一信息包括飞行用户终端的标识信息。需要注意的是，尽管在图3中只示出了第一通信设备300的一个单元，但这只是示意性的，第一通信设备300也可以包括多个其他单元，这些单元由于与发明构思无关而被省略。
在该实施例中，发送单元310发送的第一信息可以是表明其为飞行用户终端的信息，而不是普通用户设备或终端的信息。这里，第一通信设备300和第二通信设备例如可以分别是图1所示的第一基站110和第二基站120，以及飞行用户终端可以是图1所示的飞行用户终端150。
通过本实施例，第一通信设备可以将飞行用户终端的标识信息发送至第二通信设备，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行检测、抑制、避免等干扰管理。
需要认识到，当第一通信设备300作为多个飞行用户终端的服务基站时，发送单元310向第二通信设备发送的第一信息可以包括其服务的多个飞行用户终端中的部分或全部飞行用户终端的标识信息。例如，第一通信设备300可以获取其服务的多个飞行用户终端的标识信息，然后通过发送单元310将该多个飞行用户终端中的部分或全部飞行用户终端的标识信息以列表的形式包括在第一信息中，并发送给第二通信设备。
根据本实施例的一个示例，发送单元310发送的第一信息还可以包括飞行用户终端的运动状态信息、飞行用户终端的位置状态信息、飞行用户终端的无线资源测量信息、飞行用户终端的配置信息、飞行用户终端的调度信息中的至少一个。具体描述如上文所述。
在该示例中，发送单元310将飞行用户终端标识信息以及运动状态信息、位置状态信息、无线资源测量信息、配置信息或调度信息中的至少一个发送给第二通信设备，以便对第二通信设备遭受的来自该 飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行更为准确地检测、抑制、避免等干扰管理。
此外，根据本实施例的一个示例，发送单元310还可以被配置为在发送第一信息之前主动地选择第二通信设备。例如，发送单元310还可以被配置为在发送第一信息之前，从多个候选通信设备中选择第二通信设备，比如，多个候选通信设备可以是与第一通信设备300相邻的多个通信设备。上文已经提到，第一通信设备300可以是图1所示的第一基站110。返回参照图1，第一基站110的相邻基站即第二基站120、第三基站130可以为这里的多个候选通信设备。
根据本实施例的另一示例，发送单元310也可以被配置为被动地选择第二通信设备，然后将第一信息发送至第二通信设备。例如，发送单元310可以将向第一通信设备300发送请求的通信设备作为第二通信设备。比如，第一通信设备300还可以包括接收单元320，其被配置为接收第二通信设备发送的对第一信息的第一请求，而发送单元310可以被配置为响应于第一请求，向第二通信设备发送第一信息。
在该示例中，接收单元320接收到的第一请求可以是第二通信设备向第一通信设备300请求其服务的部分或全部飞行用户终端的信息，比如标识信息、运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。例如，第二通信设备可以只向第一通信设备300请求其服务的全部飞行用户终端的标识信息，则响应于第二通信设备的请求，发送单元310可以将其服务的全部飞行用户终端的标识信息包括在第一信息中，然后发送给第二通信设备。
又例如，第二通信设备可以向第一通信设备300请求其服务的部分飞行用户终端(比如飞行高度相对较高的飞行用户终端)的标识信息和运动状态信息。进而，响应于第二通信设备的请求，发送单元310可以将这部分飞行用户终端的标识信息和运动状态信息包括在第一信息中，然后发送给第二通信设备。
在该示例中，接收单元320接收到的第一请求还可以是其他设备经由第二通信设备向第一通信设备300请求其服务的部分或全部飞行用户终端的信息，比如标识信息、运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。例如，其他设备可以将向第一通信设备300的请求信息发送给第二通信设备，第二通信设备在接收到该请求信息后，可以对请求信息进行处理，并将处理后的请求信息发送给接收单元320。当然，第二通信设备也可以不对该请求信息进行处理，而是将该请求信息直接发送给接收单元320。
此外，当接收单元320接收到的第一请求只请求飞行用户终端的标识信息时，接收单元320还可以在发送飞行用户终端的标识信息之后再接收第二通信设备发送的另一请求，该另一请求可以请求除了飞行用户终端的标识信息以外的、飞行用户终端的其他信息，比如对飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。可替换地，该另一请求还可以请求飞行用户终端的标识信息以及飞行用户终端的其他信息，比如对飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。
例如，根据本实施例的一个示例，接收单元320还可以被配置为接收第二通信设备发送的第二请求，其中，第二请求包括对飞行用户终端的运动状态信息、飞行用户终端的位置状态信息、飞行用户终端的无线资源测量信息、飞行用户终端的配置信息、飞行用户终端的调度信息中的至少一个的请求信息，以及发送单元310还可以被配置为响应于第二请求，向第二通信设备发送其请求的信息。
在该示例中，第二请求可以是对多个飞行用户终端中的部分飞行用户终端的标识信息以外的、其他信息的请求，比如对部分飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个的请求。
此外，为了使更远的不相邻的(或者没有通信接口的，例如X2接口)通信设备也可以获知第一信息，发送单元310向第二通信设备 发送第一信息时，可以指示第二通信设备将接收到的第一信息转发给其他通信设备。例如，根据本实施例的一个示例，发送单元310还可以被配置为向第二通信设备发送第二信息，其中，第二信息包括对第一信息进行转发的信息。
在该示例中，对第一信息进行转发的信息可以包括对第一信息进行转发的次数。或者，在该示例中，对第一信息进行转发的信息还可以包括第一信息被转发到的基站的集合信息。
通过上述实施例，第一通信设备可以将飞行用户终端的有关信息发送至第二通信设备，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行检测、抑制、避免等干扰管理。
下面，参照图4A和图4B来描述根据本公开的一个实施例的与图2A和图2B所示的方法200相对应的接收侧的无线通信方法400。图4A是根据本公开的一个实施例的另一无线通信方法400的流程图。图4B是根据本公开的一个实施例的另一无线通信方法400的另一流程图。如图4A所示，在步骤S402中，第二通信设备从第一通信设备接收第一信息，其中，该第一信息包括飞行用户终端的标识信息。该步骤中的第一信息可以是表明其为飞行用户终端的信息，而不是普通用户设备或终端的信息。这里，第一通信设备和第二通信设备例如可以分别是图1所示的第一基站110和第二基站120，以及飞行用户终端可以是图1所示的飞行用户终端150。
在该实施例中，飞行用户终端的标识信息可以包括能够唯一地标识飞行用户终端的信息，具体如上文所述。
通过本实施例，第二通信设备可以从第一通信设备接收其服务的飞行用户终端的标识信息，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行检测、抑制、避免等干扰管理。例如，以上行干扰为例，第二通信设备在获知该飞行用户终端的标识信息后，第二通信设备可以检测该飞行用户终端的存在并采取某些操作以抑制来自该飞行用户终端的干扰。具体地，比如第二通信设备可以 跟踪该飞行用户终端并预测该飞行用户终端的干扰水平以避免干扰，而且在必要时第二通信设备还可以发起与第一通信设备的合作以抑制干扰。
根据本实施例的一个示例，步骤S402中的第一信息还可以包括飞行用户终端的运动状态信息、飞行用户终端的位置状态信息、飞行用户终端的无线资源测量信息、飞行用户终端的配置信息、飞行用户终端的调度信息中的至少一个。具体描述如上文所述。
在该示例中，第二通信设备从第一通信设备接收其服务的飞行用户终端标识信息以及运动状态信息、位置状态信息、无线资源测量信息、配置信息或调度信息中的至少一个，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行更为准确地检测、抑制、避免等干扰管理。
此外，根据本实施例的一个示例，在第二通信设备从第一通信设备接收第一信息之前，可以被动地由第一通信设备选择。例如，在步骤S402之前，第二通信设备可以是第一通信设备从多个候选通信设备中选择的，比如，多个候选通信设备可以是与第一通信设备相邻的多个通信设备。上文已经提到，第一通信设备可以是图1所示的第一基站110。返回参照图1，第一基站110的相邻基站即第二基站120、第三基站130可以为这里的多个候选通信设备。
在这种情形下，第二通信设备可以是第一通信设备从多个候选通信设备中任意选择的，比如选择第二基站120作为第二通信设备。或者，第二通信设备可以是第一通信设备根据飞行用户终端的无线资源测量信息，比如RSRP报告，从多个候选通信设备中选择遭受飞行用户终端的干扰较为严重的通信设备(比如第二基站120)作为第二通信设备。或者，第二通信设备可以是第一通信设备根据飞行用户终端的运动状态信息，比如飞行速度、飞行方向等，从多个候选通信设备中选择可能遭受飞行用户终端的干扰较为严重的通信设备(比如第二基站120)作为第二通信设备。
根据本实施例的另一示例，第二通信设备也可以主动地向第一通信设备发起对第一信息的请求，然后接收第一信息。比如，在步骤S402之前，方法400还可以包括步骤S401，如图4A所示。在步骤S401中，第二通信设备向第一通信设备发送对第一信息的第一请求。进而，第一通信设备响应于第一请求而发送第一信息，相应地，第二通信设备接收第一信息。
在该示例中，步骤S401中的第一请求可以是第二通信设备向第一通信设备请求其服务的部分或全部飞行用户终端的信息，比如标识信息、运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。例如，第二通信设备可以只向第一通信设备请求其服务的全部飞行用户终端的标识信息，则响应于第二通信设备的请求，第一通信设备可以将其服务的全部飞行用户终端的标识信息包括在第一信息中，然后发送给第二通信设备。
又例如，第二通信设备可以向第一通信设备请求其服务的部分飞行用户终端(比如飞行高度相对较高的飞行用户终端)的标识信息和运动状态信息。进而，响应于第二通信设备的请求，第一通信设备可以将这部分飞行用户终端的标识信息和运动状态信息包括在第一信息中，然后发送给第二通信设备。
此外，当第二通信设备发送的第一请求只请求飞行用户终端的标识信息时，第二通信设备还可以在接收到飞行用户终端的标识信息之后再发送另一请求，该另一请求可以请求除了飞行用户终端的标识信息以外的、飞行用户终端的其他信息，比如对飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。可替换地，该另一请求还可以请求飞行用户终端的标识信息以及飞行用户终端的其他信息，比如对飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。
例如，根据本实施例的一个示例，在步骤S402之后，方法400还可以包括步骤S403，如图4B所示。在步骤S403中，第二通信设备向第一通信设备发送第二请求，其中，第二请求包括对飞行用户终 端的运动状态信息、飞行用户终端的位置状态信息、飞行用户终端的无线资源测量信息、飞行用户终端的配置信息、飞行用户终端的调度信息中的至少一个的请求信息。进而，第一通信设备响应于第二请求而向第二通信设备发送其请求的信息，相应地，第二通信设备接收其请求的信息。
在该示例中，第二请求可以是对多个飞行用户终端中的部分飞行用户终端的标识信息以外的、其他信息的请求，比如对部分飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个的请求。
此外，为了使更远的不相邻的(或者没有通信接口的，例如X2接口)通信设备也可以获知第一信息，第二通信设备从第一通信设备接收第一信息时，还可以接收第一通信设备指示第二通信设备将接收到的第一信息转发给其他通信设备的信息。例如，根据本实施例的一个示例，在步骤S402时或之后，方法400还可以包括步骤S404，如图4B所示。在步骤S404中，第二通信设备从第一通信设备接收第二信息，其中，第二信息包括对第一信息进行转发的信息。而且，在步骤S404之后，方法400还可以包括步骤S405，如图4B所示。在步骤S405中，第二通信设备根据第二信息判断是否满足转发条件，如果第二通信设备满足转发条件，第二通信设备转发第一信息。
在该示例中，对第一信息进行转发的信息可以包括对第一信息进行转发的次数。例如，对第一信息进行转发的次数可以为对第一信息进行跳转发送的跳数。也就是说，可以通过多跳的方式将第一信息转发给多个基站。上文已经提到，第一通信设备和第二通信设备可以分别是图1所示的第一基站110和第二基站120。返回参照图1，第一基站110可以将对第一信息进行跳转发送的跳数发送给第二基站120，则第二基站120接收到跳数之后，可以根据跳数判断是否满足转发条件，如果是，则转发第一信息。另外，当第二基站120接收到跳数后，根据跳数可能会判断出不满足转发条件，则第二基站120可以不转发第一信息，也可以通过其他方式将第一信息传递给其他基站。例如，当第二基站120接收到跳数后，第二基站120可以对接收到的跳数进 行数学运算(即减一运算)以获得更新后的跳数，然后判断更新后的跳数是否非零，如果是，则可以判断第二基站120满足转发条件，否则，则可以判断第二基站120不满足转发条件。另外，在第二基站120满足转发条件时，第二基站120还可以将更新后的跳数和第一信息转发给下一个基站。需要注意的是，第二基站120并不会将第一信息转发回第一基站110。
在此，以第二基站120接收到的跳数为3为例进行说明。例如，第二基站120通过X2接口从第一基站110接收到跳数为3，由于第一信息已经被第一基站110向第二基站120转发了一次，因此，第二基站120可以对跳数进行减一运算并获得更新后的跳数2。由于更新后的跳数2非零，因此，第二基站120满足转发条件，进而第二基站120可以通过X2接口将第一信息及更新后的跳数2转发给第四基站140。第四基站140可以执行与第二基站120类似的操作，直到不满足转发条件，可以停止对第一信息的转发。需要注意的是，第二基站120并不会将第一信息转发回第一基站110。由此可见，通过多跳的方式，第一通信设备经由第二通信设备将第一信息转发到其相邻的基站以及更远的基站，使得更远的基站也可以获知第一通信设备服务的飞行用户终端的相关信息，以便进行干扰管理。
在该示例中，对第一信息进行转发的信息还可以包括第一信息可以被转发到的基站的集合信息。也就是说，可以将第一信息转发至基站集合中的一个或多个基站。上文已经提到，第一通信设备和第二通信设备可以分别是图1所示的第一基站110和第二基站120。返回参照图1，第一基站110可以确定第一信息被转发到的基站的集合信息例如可以为{第二基站120，第三基站130，第四基站140}，则第一基站110可以将基站的集合信息发送至基站集合中的、与第一基站110相邻的基站，比如第二基站120、第三基站130。由于基站集合中的、与第一基站110不相邻的基站，比如第四基站140，和第一基站110之间不能直接通信，因此第一基站110不能把第一信息发送给第四基站140。下面以第一基站110将第一信息发送给第二基站120为例进行说明。当第二基站120接收到基站的集合信息后，可以根据基站的 集合信息判断是否满足转发条件，如果是，则转发第一信息。例如，第二基站120可以判断基站的集合信息中是否存在自己的相邻基站，比如是否存在第二基站120的相邻基站第四基站140，如果是，则可以将第一信息转发至基站集合中的第四基站140。另外，当第二基站120接收到基站的集合信息后，根据基站的集合信息可能会判断出不满足转发条件，则第二基站120可以不转发第一信息，也可以通过其他方式将第一信息传递给其他基站。需要注意的是，第二基站120并不会将第一信息转发回第一基站110。
此外，在步骤S405中，第一基站110还可以更新基站的集合信息，并将更新后的基站的集合信息发送给下一个基站或多个基站。例如，由于第一信息已经被第一基站110转发至与第一基站110相邻的第二基站120，因此，第一基站110可以将第二基站120从基站的集合信息中删除，以获得更新后的基站的集合信息，比如{第三基站130，第四基站140}，然后将第一信息及更新后的基站的集合信息{第三基站130，第四基站140}转发给第二基站120。第二基站120可以执行与第一基站110类似的操作，直到更新后的基站的集合信息为空，可以停止对第一信息的转发。
又例如，在第一信息已经被第一基站110转发至与第一基站110相邻的第二基站120且也已经被第一基站110转发至与第一基站110相邻的第三基站130的情形下，第一基站110可以将第二基站120和第三基站130从基站的集合信息中删除，以获得更新后的基站的集合信息，比如{第四基站140}，然后将第一信息及更新后的基站的集合信息{第四基站140}转发给第二基站120和第三基站130。第二基站120和第三基站130都可以执行与第一基站110类似的操作，即将与其相邻的第四基站140从基站的集合信息中删除，然后将第一信息及空的基站集合信息转发给第四基站140，或者只将第一信息转发给第四基站140。第四基站140接收到第一信息后，不再转发第一信息。由此可见，通过这种方式，第一通信设备经由第二通信设备也可以将第一信息转发到其相邻的基站以及更远的基站，使得更远的基站也可 以获知第一通信设备服务的飞行用户终端的相关信息，以便进行干扰管理。
此外，根据本实施例的一个示例，第二通信设备可以周期性地从第一通信设备接收第一信息和/或第二信息。例如，在第一通信设备周期性地接收飞行用户终端的无线资源测量报告，比如RSRP报告后，可以周期性地发送第一信息和/或第二信息。相应地，第二通信设备可以周期性地执行步骤S402和/或S404。
根据本实施例的另一示例，第二通信设备可以非周期性地从第一通信设备接收第一信息和/或第二信息。例如，第一通信设备可以根据无线通信系统的网络状态来确定何时向第二通信设备发送第一信息和/或第二信息。比如，在无线通信系统的网络状态较差时，可以为飞行用户终端设定最小需要测量的小区数目，以触发飞行用户终端向第一通信设备报告无线资源测量的结果，使得小区测量完成后飞行用户终端向第一通信设备报告。在此情形下，第一通信设备接收到飞行用户终端的无线资源测量报告后可以发送第一信息和/或第二信息。相应地，第二通信设备可以执行步骤S402和/或S404。
通过上述实施例，第二通信设备可以从第一通信设备接收其服务的飞行用户终端的有关信息，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行检测、抑制、避免等干扰管理。
下面，参照图5来描述根据本公开一个实施例的执行图4A和图4B所示的方法400的第二通信设备500。图5示出了根据本公开的一个实施例的第二通信设备500的结构示意图。由于第二通信设备500的功能与在上文中参照图4A和图4B描述的方法的细节相同，因此在这里为了简单起见，省略对相同内容的详细描述。
如图5所示，第二通信设备500包括接收单元510，其被配置为从第一通信设备接收第一信息，其中，该第一信息包括飞行用户终端的标识信息。该步骤中的第一信息可以是表明其为飞行用户终端的信息，而不是普通用户设备或终端的信息。这里，第一通信设备和第二通信设备500例如可以分别是图1所示的第一基站110和第二基站 120，以及飞行用户终端可以是图1所示的飞行用户终端150。
在该实施例中，第一通信设备与第二通信设备可以预先协商或预先确定用于发送第一信息的数据格式，以便当第一通信设备以该数据格式发送第一信息且接收单元510接收到以该数据格式发送的第一信息时，第二通信设备可以获知该第一信息是与飞行用户终端有关的信息而不是与普通用户设备或终端有关的信息。
通过本实施例，第二通信设备可以从第一通信设备接收其服务的飞行用户终端的标识信息，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行检测、抑制、避免等干扰管理。
根据本实施例的一个示例，接收单元510接收到的第一信息还可以包括飞行用户终端的运动状态信息、飞行用户终端的位置状态信息、飞行用户终端的无线资源测量信息、飞行用户终端的配置信息、飞行用户终端的调度信息中的至少一个。具体描述如上文所述。
在该示例中，接收单元510从第一通信设备接收其服务的飞行用户终端标识信息以及运动状态信息、位置状态信息、无线资源测量信息、配置信息或调度信息中的至少一个，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行更为准确地检测、抑制、避免等干扰管理。
此外，根据本实施例的一个示例，在第二通信设备从第一通信设备接收第一信息之前，可以被动地由第一通信设备选择。例如，在接收单元510接收第一信息之前，第二通信设备可以是第一通信设备从多个候选通信设备中选择的，比如，多个候选通信设备可以是与第一通信设备相邻的多个通信设备。上文已经提到，第一通信设备可以是图1所示的第一基站110。返回参照图1，第一基站110的相邻基站即第二基站120、第三基站130可以为这里的多个候选通信设备。
根据本实施例的另一示例，第二通信设备也可以主动地向第一通信设备发起对第一信息的请求，然后接收第一信息。比如，第二通信设备还可以包括发送单元520，其被配置为在接收单元510从第一通 信设备接收第一信息之前，向第一通信设备发送对第一信息的第一请求。进而，第一通信设备响应于第一请求而发送第一信息，相应地，接收单元510接收第一信息。
在该示例中，发送单元520发送的第一请求可以是第二通信设备向第一通信设备请求其服务的部分或全部飞行用户终端的信息，比如标识信息、运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。例如，发送单元520可以只向第一通信设备请求其服务的全部飞行用户终端的标识信息，则响应于第二通信设备的请求，第一通信设备可以将其服务的全部飞行用户终端的标识信息包括在第一信息中，然后发送给接收单元510。
又例如，发送单元520可以向第一通信设备请求其服务的部分飞行用户终端(比如飞行高度相对较高的飞行用户终端)的标识信息和运动状态信息。进而，响应于第二通信设备的请求，第一通信设备可以将这部分飞行用户终端的标识信息和运动状态信息包括在第一信息中，然后发送给接收单元510。
在该示例中，发送单元520发送的第一请求还可以是其他设备经由第二通信设备向第一通信设备请求其服务的部分或全部飞行用户终端的信息，比如标识信息、运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。例如，其他设备可以将向第一通信设备的请求信息发送给第二通信设备，接收单元510在接收到该请求信息后，可以对请求信息进行处理，并将处理后的请求信息经由发送单元520发送给第一通信设备。当然，接收单元510也可以不对该请求信息进行处理，而是将该请求信息直接经由发送单元520发送给第一通信设备。
此外，当发送单元520发送的第一请求只请求飞行用户终端的标识信息时，在接收单元510接收到飞行用户终端的标识信息之后，发送单元520还可以再发送另一请求，该另一请求可以请求除了飞行用户终端的标识信息以外的、飞行用户终端的其他信息，比如对飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。可替换地，该另一请求还可以请求飞 行用户终端的标识信息以及飞行用户终端的其他信息，比如对飞行用户终端的运动状态信息、位置状态信息、无线资源测量信息、配置信息、调度信息中的一个或多个。
例如，根据本实施例的一个示例，发送单元520还可以被配置为在接收单元510从第一通信设备接收第二信息之前，向第一通信设备发送第二请求，其中，第二请求包括对飞行用户终端的运动状态信息、飞行用户终端的位置状态信息、飞行用户终端的无线资源测量信息、飞行用户终端的配置信息、飞行用户终端的调度信息中的至少一个的请求信息。进而，第一通信设备响应于第二请求而向接收单元510发送其请求的信息，相应地，接收单元510接收其请求的信息。
此外，为了使更远的不相邻的(或者没有通信接口的，例如X2接口)通信设备也可以获知第一信息，第二通信设备从第一通信设备接收第一信息时，还可以接收第一通信设备指示第二通信设备将接收到的第一信息转发给其他通信设备的信息。例如，根据本实施例的一个示例，接收单元510还可以被配置从第一通信设备接收第二信息，其中，第二信息包括对第一信息进行转发的信息。而且，发送单元520还可以被配置为根据第二信息判断是否满足转发条件，如果满足转发条件，转发第一信息。
在该示例中，对第一信息进行转发的信息可以包括对第一信息进行转发的次数。或者，在该示例中，对第一信息进行转发的信息还可以包括第一信息被转发到的基站的集合信息。
通过上述实施例，第二通信设备可以从第一通信设备接收其服务的飞行用户终端的有关信息，以便对第二通信设备遭受的来自该飞行用户终端的干扰(即上行干扰)和/或该飞行用户终端遭受的来自第二通信设备的干扰(即下行干扰)进行检测、抑制、避免等干扰管理。
