图1是本申请实施例的应用场景示意图。如图1所示,本申请实施例中,IAB节点可以为用户设备(user equipment,UE)提供无线接入服务,该UE的业务数据由IAB节点通过无线回传链路连接到IAB宿主(IAB donor)传输。IAB节点可以包括移动终端(mobile termination,MT)部分和分布式单元(distributed unit,DU)部分,其中,IAB节点的MT部分,具有UE的部分或全部功能。当IAB节点面向其父节点时,其被视为终端设备,即作为MT的角色;当IAB面向其子节点(子节点可能是另一IAB节点,或者普通UE)时,其被视为网络设备,即作为DU的角色。
本申请实施例中IAB donor也可称为宿主节点(donor node)或宿主基站(donor gNodeB,DgNB)。IAB donor连接到为UE服务的核心网(例如连接到5G核心网,5GC)网元,并为IAB节点提供无线回传功能。
需要说明的是,IAB donor可以是一个具有完整基站功能的接入网网元,也可以是集中式单元(centralized unit,CU)和分布式单元(distributed unit,DU)分离的接入网网元,宿主基站为便于表述,将宿主节点的集中式单元简称为IAB donor CU(或直接称为CU),宿主节点的分布式单元简称为IAB donor DU,其中donor CU可以是控制面(control plane,CP)和用户面(user plane,UP)分离的形态,示例性地,CU可由一个CU-CP和一个(或多个)CU-UP组成。
在IAB网络中可以采用多跳组网,提高网络的覆盖性能;也可以采用多连接组网,提高业务传输的可靠性;还可以将多跳组网和多连接组网结合,兼顾网络的覆盖性能和业务传输的可靠性。
在由IAB节点服务的UE和IAB donor之间,存在至少一条由多段链路组成的传输路径。在一条传输路径上,可以包括UE、一个或多个IAB节点和IAB donor,其中,若IAB donor为CU和DU分离的形态,则传输路径还可以包括IAB-donor-DU部分和IAB-donor-CU部分,每个IAB节点将为其提供接入和回传服务的相邻节点视为父节点,相应地,每个IAB节点可视为其父节点的子节点。
在IAB网络中,在无线回传链路引入回传适配协议(backhaul adaptation protocol,BAP)层,该协议层位于RLC层之上,可用于实现数据包在无线回传链路的路由,以及承载映射等功能。
在IAB节点的MT部分和宿主节点(具体可以是IAB-donor-CU)可以建立RRC连接,宿主节点也可以通过RRC连接给IAB-MT发送RRC消息,也可以接受来自IAB-MT的RRC消息,用于进行无线资源管理相关的功能。
在IAB节点的DU部分(IAB-DU部分)和宿主节点(具体可以是IAB-donor-CU)之间,需要建立F1接口(或者被称为F1*接口,本申请中,可统一称为F1接口,但对名 称并不做限定),该接口支持用户面协议(F1-U/F1*-U)和控制面协议(F1-C/F1*-C)。
其中,如图2的IAB网络用户面协议栈架构的示意图所示,用户面协议包括以下协议层的一个或多个:通用分组无线服务(general packet radio service,GPRS)隧道协议用户面(GPRS tunnelling protocol user plane,GTP-U)、用户数据报协议(user datagram protocol,UDP)、因特网协议(internet protocol,IP)。
如图3的IAB网络控制面协议栈架构的示意图所示,该接口的控制面协议包括以下中的一个或者多个:F1应用协议(F1 application protocol,F1AP)、流控传输协议(stream control transport protocol,SCTP)、IP。通过F1/F1*接口的控制面,IAB节点和IAB宿主之间可以进行执行接口管理,对IAB-DU进行管理,以及执行UE上下文相关的配置等。通过F1/F1*接口的用户面,IAB节点和IAB宿主之间可以执行用户面数据的传输,以及下行传输状态反馈等功能。
本申请实施例中,第一设备可以是基站的分布式单元,网络设备可以是基站的集中式单元或者基站的集中式单元的控制面部分(gNB-CU-CP);进一步地,第一设备可以是IAB节点或者IAB节点的分布式单元,第一网络设备可以是第一设备的宿主基站,也可以是第一设备宿主基站的集中式单元或第一设备宿主基站的CU-CP;再进一步,第一设备还可以是移动IAB节点或者移动IAB节点的分布式单元,第一网络设备可以是第一设备的宿主基站,或者是第一设备的宿主基站的集中式单元,第一网络设备还可以是第一设备的宿主基站的CU-CP本申请对此不做限定。本申请中,第一设备的宿主基站,可以理解是与第一设备之间建立F1接口的宿主基站。为方便描述,以下实施例中,第一设备选择移动IAB节点,第一网络设备为第一设备的宿主基站,本申请实施例对于其他情形也一样适用。
图4是本申请一实施例方法400的流程示意图,本申请实施例中,第一设备是移动IAB节点,第一网络设备是第一基站,第一网络设备同时是第一设备的宿主基站,第二网络设备是第二基站。

具体地,第二基站可以在与第一基站建立Xn接口时,发送第一信息。
在一种可能的实现方式中,可以是第二基站周期性地主动向第一基站发送第一信息,也可以是第二基站周期性地接收到第二基站的请求后发送第一信息,该周期可以是第二基站中预先配置的,本申请在此不做限定。
在一种可能的实现方式中,当第二基站所辖的小区信息发生更新或者当第二基站的邻居基站所辖的小区发生更新并通知第二基站时,第二基站向第一基站发送第一信息,第一信息中包括更新后的小区列表。
具体地,基站所辖的小区发生更新,可以是该基站下新增了一个或一些小区,或者是该基站下关闭了一个或一些小区,或者该基站下的小区的标识(PCI,或CGI)发生了变更。
在一种可能的实现方式中,第一信息中还包括第二基站的邻居基站(例如第三基站)所辖的小区信息列表,第三基站所辖的小区信息列表中包括第三基站所辖的一个或多个小 区信息。可以理解为第一信息中中包括与第一基站邻近的基站所辖的小区信息,该邻近的基站可以是第一基站的邻居基站,或者第一基站的邻居的邻居基站,本申请对此不做限定。
本申请中,第一基站的邻居基站可以是与第一基站之间有Xn接口的基站,第二基站的邻居基站可以是与第二基站之间有Xn接口的基站。其中,第一信息中,第二基站所辖的小区信息或者第三基站所辖小区的信息包括小区的物理小区标识PCI,还可以包括如下中的至少一种:小区全局标识(cell global identity,CGI),小区广播的跟踪区域码(tracking area code,TAC),小区广播的无线接入网区域码(RAN area code,RANAC),小区广播的PLMN列表。
S420,第一设备接收来自第一基站的第一列表。
在一种可能的实现方式中,第一列表可以通过RRC消息发送给第一设备的MT部分。
在一种可能的实现方式中,第一列表还可以通过F1AP消息发送给第一设备的DU部分。
第一列表是第一基站根据第一信息生成的,第一列表中包括N个第一小区的信息,每个所述第一小区的信息对应一个第一小区,第一小区是第一基站或第二基站服务的小区,每个第一小区的信息中,包括第一小区的PCI,还可以包括如下中的至少一种:第一小区的小区全局标识(cell global identity,CGI),第一小区广播的TAC,小区广播的RANAC,第一小区广播的PLMN列表。示例性地,第一小区的CGI是第一小区的全局唯一标识,由PLMN标识和小区标识共同组成,NR(New Radio)制式的第一小区的CGI是NCGI(NR CGI);E-UTRA制式的第一小区的CGI是ECGI(E-UTRA CGI)。
其中,第一基站服务的小区,可以是第一基站服务的小区中除了该第一设备服务的小区之外的其他小区。
一种可能的方式中,第一小区还可以是第一基站的邻居的邻居基站服务的小区,示例性地,第三基站是第二基站的邻居基站,与第一基站之间没有Xn接口,但第三基站服务的小区的信息,也可以包括在第一基站向第一设备发送第一列表中。
本申请实施例中,第一基站服务的小区和邻居基站(第二基站或第三基站)服务的小区可以通过同一列表配置给第一设备,也可以通过两个不同的列表配置给第一设备,本申请实施例对此不做限定。
在一种可能的实现方式中,S430,第一设备获取来自OAM的第二信息。
在一种可能的实现方式中,第二信息包括第二列表,第二列表是包括一组可用的PCI的列表(或者称为候选PCI list),具体地,OAM预配置可用的PCI列表在第一设备中,或者第一设备初始入网认证后,连接到OAM获取可用的PCI列表;或者第一设备在移动过程中从OAM获取到更新的可用PCI列表。
在一种可能的实现方式中,第二信息包括第三列表,第三列表是包括一组不可用的PCI的列表。
需要说明的是,S430和S410、S420没有先后顺序。
S440,第一设备根据第一列表确定PCI。
示例性地,第一设备基于第一列表判断出来其服务的小区PCI或初始启动过程中配置的小区PCI和周围的其他小区的PCI相同,为了避免干扰需要更换PCI。又如第一设备在启动过程中,需要为其服务的小区确定将要采用的PCI。
在一种可能的实现方式中,第一设备在OAM配置的可用PCI list中选择一个可用的PCI时,避开第一列表中包括的PCI。
在一种可能的实现方式中,第一设备在PCI的全集中,避开OAM提供的不可用PCI列表,并避开在第一列表中包括的PCI,从余下的可用PCI中选择一个。
本申请实施例中,宿主基站提供邻居小区的信息列表(其中包括PCI)给移动IAB节点,可以使得移动IAB节点避开这些PCI,选择一个不冲突的PCI,避免对周围小区造成强干扰。
图5是本申请一实施例方法500的流程示意图,本申请实施例中,第一设备是移动IAB节点,第一网络设备是第一基站,第二网络设备是第二基站。
S510,第一基站接收来自第二基站的第一信息,第一信息中包括第二基站所辖的小区信息列表,还可以包括第二基站的邻居基站(例如第三基站)所辖的小区信息列表。其中,第二基站是第一基站的邻居基站,第三基站是第二基站的邻居基站。
具体描述参见本申请实施例方法400中的步骤S410,与S410不同的是本申请实施例中,第一信息中,第二基站所辖的小区信息或者第三基站所辖小区的信息,还包括可以用于指示小区是否是mobile IAB node所服务的小区。一种可能的实现方式中,可以显性指示小区是否是mobile IAB node所服务的小区,示例性地,在第一信息中,可以对于mobile IAB node所服务的小区,在相应的小区信息中携带显式的指示mobile IAB node indicator。或者,在第一信息中,单独包括有一个分组是mobile IAB node服务的小区列表,那在该分组内的小区都是mobile IAB node所服务的小区,例如第一信息中,包括第二基站所辖的mobile IAB node服务的小区信息列表,还可以包括第三基站所辖的mobile IAB node服务的小区信息列表,包括在这两个列表中的小区都是mobile IAB node所服务的小区。
又一种可能的实现方式中,第一信息中可以隐性指示小区是否是mobile IAB node所服务的小区,示例性,可以预先将mobile IAB node专用的PCI集合或者预留给mobile IAB node专用的PCI的取值范围通过OAM配置给第一基站,这样基于第一信息中的小区信息中的具体的PCI的取值,第一基站就可以识别mobile IAB node所服务的小区。
在一种可能的实现方式中,第二基站下也有mobile IAB node,这些mobile IAB node从OAM处获取的候选PCI list会通过RRC消息或者F1AP消息上报给第二基站,因此第二基站在提供自己所辖小区的信息给第一基站时,其中包括的mobile IAB node所服务的小区信息中,可以包括这些mobile IAB node的候选PCI list的所有PCI。类似的,第二基站的邻居基站(例如第三基站)给第二基站提供的服务的小区信息中也可以包括连接到第三基站的mobile IAB node的候选PCI list中的所有PCI。相应地,第二基站在提供邻居基站所辖的小区信息给第一基站时,也包括了连接到第三基站的mobile IAB node的候选PCI list中的所有PCI。
进一步地,在第二基站以及其邻居基站所辖的小区信息中,指示出哪些小区是固定IAB节点(fixed IAB node)所服务的小区,哪些小区是mobile IAB node服务的小区,哪些是基站或者基站的DU所服务的小区。
S520,第一设备接收来自第一基站的第一列表。
具体描述参见本申请实施例方法400中的步骤S420,与S420不同的是第一小区的信息还可以指示小区是否是mobile IAB node所服务的小区,进一步地,还可以哪些小区是 fixed IAB node所服务的小区,哪些小区是mobile IAB node服务的小区,哪些是基站或者基站的DU所服务的小区,具体的指示方式参见S510,在此不做赘述。
可选地,S530,第一设备接收来自OAM的第二信息。
具体描述参见本申请实施例方法400中的步骤S430,在此不做赘述。
S540,第一设备根据第一列表选择PCI。
具体描述参见本申请实施例方法400中的步骤S440,在此不做赘述。
本步骤中,在方法400中步骤S440的描述基础上,还可以结合第一设备的设备类型来选择PCI,例如,如果第一设备是mobile IAB node,则第一设备在选择PCI的时候,可以从OAM配置的可用PCI列表中,选择不与第一列表中的mobile IAB node所服务的小区的PCI相同的PCI。又如,如果第一设备是固定的IAB节点,则第一设备在选择PCI的时候,可以从OAM配置的可用PCI列表中,选择不与第一列表中的固定IAB节点所服务的小区PCI相同、也不与第一列表中基站的DU所服务的小区PCI相同的PCI。
相比于方法400,本申请实施例既保障了移动IAB节点对固定小区的PCI没有影响,又通过提前通知移动IAB节点周围较大范围内的移动IAB节点使用的PCI,可以尽量避开移动IAB节点之间的PCI冲突造成的干扰。此外,在基站之间交互的小区信息,以及作为宿主节点的基站向移动IAB节点发送的邻居小区信息中,还可以进一步指示小区是移动IAB小区,或固定IAB节点小区,或固定基站的小区。
图6是本申请一实施例方法600的流程示意图,本申请实施例中,第一设备是移动IAB节点,第一网络设备是第一基站,第二网络设备是第二基站。
S610,第一基站接收来自第二基站的第一信息,具体描述参见本申请实施例方法400和500中步骤S410和S510,在此不做赘述。
S620,第一基站根据第一信息获取第一列表,关于第一列表的描述参见本申请实施例方法400和500中步骤S420和S520,在此不做赘述。
S630,第一设备向第一基站发送第一标识信息,第一标识信息用于表示第一设备服务的小区,第一标识信息可以包括第一设备服务小区的PCI。
示例性地,在F1setup的过程中,第一设备的DU部分在F1setup request消息中携带自己的小区信息,其中包括每个小区的PCI。
在一种可能的实现方式中,第一标识信息还可以包括第一设备服务的小区的小区全局标识、第一设备服务的小区的跟踪区域码、第一设备服务的小区的无线接入网区域码和第一设备服务的小区的陆地移动公共网络列表中的至少一项。
S640,第一设备还可以向第一基站发送第二标识信息列表,所述第二标识信息列表中包括一个或多个第二标识信息,第二标识信息与第一设备检测到的邻居小区一一对应,其中所述第二标识信息包括第一设备检测到的邻居小区的物理小区标识。示例性地,第一设备是mobile IAB节点,该mobile IAB节点的MT部分或者DU部分,在小区搜索或者测量时候检测到的小区的PCI都记录下来,然后将这些PCI包括在第二标识信息列表中发送给第一基站。
在一种可能的实现方式中,如果OAM划分了mobile IAB node专用的PCI范围或者PCI集合,这种情况下,第一设备在第二标识信息中还可以具体指示出每个PCI所对应小区的服务节点类型,服务节点类型例如是mobile IAB node服务的小区,或者固定节点服 务的小区,对于固定节点可进一步指示出是固定的IAB节点还是基站或者基站的DU。具体指示服务节点的方式,可以参考前述实施例中的描述进行理解。示例性的,第一设备可以通过读取邻居小区的系统广播确定邻居小区的服务节点的类型是mobile IAB node,譬如mobile IAB node可以在自己服务的小区系统信息广播中,携带指示自己为mobile IAB node的指示信息;或者,第一设备从OAM处获取mobile IAB节点服务小区的PCI范围或PCI集合,然后在检测到邻居小区的PCI时,如果PCI属于mobile IAB节点服务小区的PCI范围或PCI集合,则可以确定邻居小区的服务节点的类型是mobile IAB node。
一种可能的方式中,第二标识信息列表中的每个第二标识信息,还包括第一设备检测到的邻居小区的如下中的任意一项或者多项:小区的CGI、小区广播的TAC、小区广播的PLMN标识,小区广播的RANAC。
一种可能的方式中,步骤S640与步骤S630可以合并为一个步骤,即第一设备在向第一基站发送第一标识信息的时候,也携带第二标识信息列表。
需要说明的是,本申请实施例中,步骤S640,S630,S610的顺序不限定。
S650,第一基站根据第一标识信息、第二标识信息列表和第一列表确定第三标识信息列表,第三标识信息列表中包括一个或多个第三标识信息,第三标识信息包括第一基站为第一设备选择的可用PCI。
具体地,第一基站基于第一标识信息、第二标识信息列表和第一列表,检测第一设备是否可能和周围的邻居小区发生PCI冲突,如果是,则第一基站为第一设备选择一个不会与周围的小区冲突的PCI,然后通过F1接口通知第一设备的DU部分,或者通过RRC消息通知第一设备的MT部分。这里所说的周围的邻居小区,包括第一列表中的小区、第二标识信息列表中的小区,以及第一基站自己所辖的小区。
示例性地,第一设备是mobile IAB节点,若OAM划分了mobile IAB node专用的PCI范围或PCI集合,则第一基站判断周围的邻居小区中由mobile IAB节点所服务的小区的PCI是否与第一设备服务的小区冲突,并在为第一设备重配置PCI时避开这些邻居mobile IAB节点所服务的小区的PCI。
S660,第一基站向第一设备发送第三标识信息列表,所述第三标识信息列表中包括一个或多个第三标识信息。
一种可能的方式中,第一设备服务的小区有多个,第一基站可以在向第一设备发送第三标识信息列表时,携带用于指示第一设备服务的小区的标识(例如第一标识信息,或者第一标识信息中的PCI,或者第一标识信息中的CGI),用于指示第一设备将哪些小区的PCI进行更新。这种情况下,第一基站可以仅指示第一设备对于PCI与周围邻居小区发生冲突的第一设备的小区进行更新。
示例性的,第一设备为mobile IAB node,第一设备服务的小区有三个,这三个小区对应的PCI分别是PCI 1,PCI 2,PCI3,其中PCI1和PCI2与周围的邻居小区可能发生PCI冲突,则第一基站在向第一设备发送第三标识信息列表时,可以携带PCI 1和PCI 2,以及包括两个新PCI(例如PCI 4和PCI5)的第三标识信息列表,用于指示第一设备需要将原本由PCI 1和PCI2标识的小区,替换为这两个新的PCI。或者,第一基站向第一设备发送第三标识信息列表时,对应于PCI1有一个第三标识信息列表(包括PCI4),对应于PCI2有另一个第三标识信息列表(包括PCI5)。
S670,第一设备将第一标识信息所表示的小区的标识信息,替换为第三标识信息列表中的一个第三标识信息。
示例性地,第一设备为mobile IAB节点,第一设备从第一基站中收到第三标识信息列表时,在第一基站发送的消息中包括PCI 1和PCI 2,以及包括两个新PCI(例如PCI 4和PCI5)的第三标识信息列表,第一设备可以自行选择用哪一个新PCI替换PCI1/2。
另一种可能的示例中,第一设备为mobile IAB节点,第一设备从第一基站中收到第三标识信息列表时,在第一基站发送的消息中,对应于PCI1有一个第三标识信息列表(包括PCI4),对应于PCI2有另一个第三标识信息列表(包括PCI5),则第一设备从PCI 1对应的第三标识信息列表中选择一个(例如PCI4)用于替换PCI1,从PCI2对应的第三标识信息列表中选择一个(例如PCI 5)用于替换PCI2。
本申请实施例中,基站基于获取的邻居小区信息以及移动IAB节点所服务的小区的信息,检测是否有PCI冲突的可能,通过重配置PCI给移动IAB节点,可以避开移动IAB节点和周围小区之间的PCI冲突造成的干扰。
