本申请要求在2022年12月02日提交中国专利局、申请号为202211554543.9、名称为“路径控制方法、装置、终端、网络侧设备及存储介质”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
本申请属于通信技术领域,具体涉及一种路径控制方法、装置、终端、网络侧设备及存储介质。
背景技术
无线通信系统中的中继(Relay)技术,是在基站与终端之间增加一个或多个中继节点,负责对无线信号进行一次或者多次转发,即无线信号要经过多跳才能到达对端。无线中继技术不仅可用于扩展小区覆盖,弥补小区覆盖盲点,同时也可通过空间资源复用提升小区容量。
在旁链路中继(Sidelink Relay,SL Relay)架构中,与中继节点连接的终端,可以称为远端终端(Remote UE),相应的,中继节点可以称为中继终端(Relay UE)。远端终端可以通过多路径(Multiple Path,也可简称为Multi-Path,MP)与基站连接,如通过一条直连路径和至少一条非直连路径与基站连接,每条非直连路径上对应有一个或多个中继终端。在工作过程中,可能需要进行路径控制。如当远端终端移动时,可能会进行小区切换,在这种情况下,远端终端会先释放非直连路径,在单路径状态下进行小区切换,切换完成后再添加非直连路径恢复到多路径状态,再比如,基站认为信道质量情况较差时,会控制断开非直连路径,后续如有需要则会重新连接非直连路径。
目前这种方式,远端终端需要先断开与非直连路径上的中继终端的连接,从而释放非直连路径,在有需要时重新建立与中继终端的连接,从而添加非直连路径。释放非直连路径后再重新连接,重新连接的中继终端与之前断开的中继终端可能并不相同,因此无法有效保证业务连续性。

图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。
其中,终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、增强现实(augmented reality,AR)/虚拟现实(virtual reality,VR)设备、机器人、可穿戴式设备(Wearable Device)、车载设备(VUE)、行人终端(PUE)、智能家居(具有无线通信功能的家居设备,如冰箱、电视、洗衣机或者家具等)、游戏机、个人计算机(personal computer,PC)、柜员机或者自助机等终端侧设备,可穿戴式设备包括:智能手表、智能手环、智能耳机、智能眼镜、智能首饰(智能手镯、智能手链、智能戒指、智能项链、智能脚镯、智能脚链等)、智能腕带、 智能服装等。需要说明的是,本申请实施例并不限定终端11的具体类型。

为方便理解,先对本申请实施例涉及到的相关技术及概念进行介绍。
一、旁链路中继机制
无线通信系统中的中继技术,是在基站与终端之间增加一个或多个中继节点,负责对无线信号进行一次或者多次转发,即无线信号要经过多跳才能到达对端。
无线中继技术不仅可用于扩展小区覆盖,弥补小区覆盖盲点,同时也可通过空间资源复用提升小区容量。对于室内覆盖,中继技术也可起到克服穿透损耗,提升室内覆盖质量的作用。
以较简单的两跳中继为例,无线中继就是将一条基站到终端的链路分割为基站到中继站和中继站到终端两条链路,从而有机会将一条质量较差的链路替换为两条质量较好的链路,以获得更高的链路容量及更好的覆盖。
目前LTE中已经支持的中继为终端到网络中继(UE-to-Network Relay),即中继节点的一端连接终端,另一端连接网络侧设备。跟中继节点连接的终端,叫做远端终端(Remote UE),相应的,中继节点可以称为中继终端(Relay UE)。
在NR中,一种可能的终端到网络中继场景如图2所示,远端终端需要通过基站向服务器传输数据,但由于基站覆盖不佳,所以需要找到中继终端为其中转。中继终端与基站之间的接口是Uu接口,中继终端与远端终端之间的接口是旁链路(sidelink)接口,如直连通信接口(PC5接口)。一般来说,中继终端是开放的,可以为任意一个远端终端服务。
二、多路径场景
针对旁链路中继架构,多路径是指远端终端与基站之间同时建立了一条直连路径和至少一条非直连路径,非直连路径上的终端为中继终端,如图3至图5所示。图3中,远端终端与基站之间通过控制面(Control Plane,CP)和用户面(User Plane,UP)连接,中继终端与远端终端和基站之间通过用户面连接,图4中,远端终端与基站之间通过用户面连接,中继终端与远端终端和基站之间通过控制面和用户面连接,图5中,远端终端与基站之间通过控制面和用户面连接,中继终端与远端终端和基站之间通过控制面和 用户面连接。
针对非旁链路中继架构,两个终端之间的连接并不是旁链路(PC5)接口,假设它们之间为有线连接或者理想的终端间连接(ideal inter-UE connection)。在这种架构下,多路径是指主终端(Primary UE)与基站之间同时建立了一条直连路径和至少一条非直连路径,非直连路径上的终端为从终端(Secondary UE),如图6至图8所示。图6中,主终端与基站之间通过控制面和用户面连接,从终端与主终端之间为有线连接或理解的终端间连接,从终端与基站之间通过用户面连接,图7中,主终端与基站之间通过用户面连接,从终端与主终端之间为有线连接或理想的终端间连接,从终端与基站之间通过控制面和用户面连接,图8中,主终端与基站之间通过控制面和用户面连接,从终端与主终端之间为有线连接或理想的终端间连接,从终端与基站之间通过控制面和用户面连接。
三、相关概念
非直连路径,即Indirect path,是指远端终端(或主终端)通过中继终端(或从终端)以及中继终端(或从终端)的Uu接口与基站进行数据和/或消息的传输的无线链路。
直连路径,即Direct path,是指远端终端(或主终端)通过自己的Uu接口与基站进行数据和/或消息的传输的无线链路。
多路径到多路径(MP-to-MP)切换,是指与基站建立多路径的远端终端进行的小区切换,比如基站内的小区切换,即从同一个基站的一个小区切换到该基站的另一个小区,再比如跨基站的小区切换,即从一个基站的一个小区切换到另一个基站的一个小区。以远端终端跨基站切换场景为例,远端终端带着中继终端一起从基站1切换到基站2,如从图9所示位置到图10所示位置。
上面对本申请实施例涉及到的相关技术和概念进行了介绍,下面结合附图,通过一些实施例及其应用场景对本申请实施例提供的路径控制方法进行详细地说明。
参见图11所示,为本申请实施例所提供的一种路径控制方法的实施流程图,该方法可以包括以下步骤:
S1110:第一终端从第一网络侧设备接收第一信息,第一信息用于指示进行路径挂起。
本申请实施例可以应用在多种场景中,比如可穿戴终端通信场景、多路径到多路径切换场景、多路径调整场景等。以可穿戴终端通信场景为例,第一终端可以为可穿戴终端,第二终端可以为手机、平板电脑等终端。
第一终端可以通过至少两条路径与第一网络侧设备连接,至少两条路径包括一条直连路径,以及至少一条通过至少一个第二终端连接的非直连路径。
第一网络侧设备可以是基站。在旁链路中继架构中,第一终端可以是远端终端,第二终端可以是中继终端,在非旁链路中继架构中,第一终端可以是主终端,第二终端可以是从终端,第一终端和第二终端之间可以是基于理想的回程线路(ideal backhaul),或者是基于非3GPP的短距离无线接入技术的回程线路,例如wifi、蓝牙等。
本申请实施例可以在NR系统中使用,也可以扩展到在其他多路径传输系统中使用。
第一网络侧设备可以向第一终端发送第一信息,该第一信息用于指示进行路径挂起,或者指示挂起目标路径。目标路径包括至少两条路径中的部分或全部路径。
可选的,第一网络侧设备在接收到第一终端的终端辅助信息时,可以向第一终端发送第一信息,或者,第一网络侧设备可以在监测到目标路径的信道质量较差时,向第一终端发送第一信息,或者,第一网络侧设备可以在监测到第一终端的业务数据量较小时,向第一终端发送第一信息,或者,第一网络侧设备可以综合多种信息判断是否向第一终端发送第一信息。终端辅助信息可用于辅助第一网络侧设备确定是否发起路径切换命令。
第一终端从第一网络侧设备接收到第一信息后,可以继续执行后续步骤的操作。
S1120:第一终端根据第一信息,对目标路径执行路径挂起操作。
第一终端从第一网络侧设备接收到的第一信息后,可以根据第一信息,对目标路径执行路径挂起操作。该目标路径为第一终端与第一网络侧设备之间建立的至少两条路径中的部分或全部路径。第一终端可以先根据第一信息确定要执行路径挂起操作的目标路径,如将至少两条路径中的非直连路径确定为目标路径,或者,将至少两条路径中的全部路径确定为目标路径,然后对目标路径执行路径挂起操作。
对目标路径执行的路径挂起操作可以包括挂起(suspend)第一终端的端到端无线承载(E2E radio bearer)映射到该目标路径的数据和/或消息的传输。
S1130:在满足第一条件的情况下,第一终端对目标路径执行路径恢复操作。
其中,第一条件可以包括以下至少一项:
第一终端接收到第二信息,第二信息包括路径恢复指示信息;
第一终端接入到第一小区;
第一终端确定第二终端接入到第二小区。
第一终端接收到第一信息,并根据第一信息对目标路径执行路径挂起操作后,在满足第一条件的情况下,可以对目标路径执行路径恢复操作。对目标路径执行的路径恢复操作可以包括恢复(resume)第一终端的端到端无线承载到该目标路径的数据和/或消息的传输。
在第一条件包括第一终端接收到第二信息的情况下,第一终端接收到第二信息,即可根据第二信息对目标路径执行路径恢复操作。第二信息可以包括路径恢复(resume/resumption)指示信息,或者称为路径激活(activate/activation)指示信息,可以通过消息或信令传输,如通过无线资源控制(Radio Resource Control,RRC)重配置消息或MAC层的控制单元(MAC Control Element,MAC CE)信令传输。
第一终端接收到的第二信息可以是第一网络侧设备发送的,即第一网络侧设备向第一终端发送第二信息。在满足以下任意一项的情况下,第一网络侧设备向第一终端发送第二信息:第一网络侧设备确定第一终端向第一小区发起随机接入过程,且随机接入成功;第一网络侧设备接收到第一终端发送的第一消息;第一网络侧设备确定第二终端向 第二小区发起随机接入过程,且随机接入成功;第一网络侧设备接收到第二终端发送的第二消息;第一网络侧设备根据信道质量信息和/或业务数据量大小信息确定达到恢复条件。
比如,在多路径切换场景中,第一网络侧设备向第一终端发送第一信息,指示第一终端进行路径挂起,第一终端根据第一信息对目标路径执行路径挂起操作,第一网络侧设备在确定第一终端接入到第一小区和/或确定第二终端接入到第二小区的情况下,可以向第一终端发送第二信息,指示第一终端进行路径恢复,第一终端接收到第二信息后,即可对目标路径执行路径恢复操作。这里第一小区和第二小区为第一网络侧设备的小区。第二信息是在确定第一终端接入到第一小区和/或确定第二终端接入到第二小区的情况下发出的,可以保证第一终端对目标路径执行路径恢复操作后可以顺利进行数据和/或消息的传输。
再比如,在路径调整场景中,第一网络侧设备根据信道质量信息和/或业务数据量大小信息确定达到挂起条件,可以向第一终端发送第一信息,指示第一终端进行路径挂起,第一终端根据第一信息对目标路径执行路径挂起操作,第一网络侧设备根据信道质量信息和/或业务数据量大小信息确定达到恢复条件,可以向第一终端发送第二信息,指示第一终端进行路径恢复,第一终端接收到第二信息后,即可对目标路径执行路径恢复操作。可选的,当信道质量信息表征信道质量较差时,可以认为达到挂起条件,挂起第一终端的非直连路径,使用直连路径进行数据和/或消息的传输,当信道质量信息表征信道质量较好时,可以认为达到恢复条件,恢复第一终端的非直连路径,使用多路径进行数据和/或消息的传输。可选的,当业务数据量大小信息表征业务数据量较少时,可以认为达到挂起条件,挂起第一终端的非直连路径,使用直连路径进行数据和/或消息的传输,当业务数据量大小信息表征业务数据量较多时,可以认为达到恢复条件,恢复第一终端的非直连路径,使用多路径进行数据和/或消息的传输,保障数据和/或消息的传输的可靠性。
第一终端接收到的第二信息还可以是第二网络侧设备发送的。比如,在多路径切换场景中,第一网络侧设备向第一终端发送第一信息,指示第一终端进行路径挂起,第一终端根据第一信息对目标路径执行路径挂起操作,第二网络侧设备在确定第一终端接入到第一小区和/或确定第二终端接入到第二小区的情况下,向第一终端发送第二信息,指示第一终端进行路径恢复,第一终端接收到第二信息后,即可对目标路径执行路径恢复操作。这里第一小区和第二小区为第二网络侧设备的小区。同样,第二信息是在确定第一终端接入到第一小区和/或确定第二终端接入到第二小区的情况下发出的,可以保证第一终端对目标路径执行路径恢复操作后可以顺利进行数据和/或消息的传输。
在第一条件包括第一终端接入到第一小区的情况下,第一终端在接入到第一小区之后,可以对目标路径执行路径恢复操作。
在第一条件包括确定第二终端接入到第二小区的情况下,第一终端在确定第二终端接入到第二小区之后,可以对目标路径执行路径恢复操作。可选的,在多路径切换场景 中,第一终端在接收到第二信息时,可以确定第二终端接入到第二小区,或者,第一终端在接收到第二终端发送的切换完成信息时,可以确定第二终端接入到第二小区。
在目标路径包括直连路径的情况下,第一条件可以包括第一终端接入到第一小区,或第一终端接收到第二信息。即第一终端在接入到第一小区或者接收到第二信息时,可以恢复到直连路径的数据和/或消息的传输。
在目标路径包括非直连路径的情况下,第一条件可以包括第一终端接收到第二信息,或第一终端确定第二终端接入到第二小区。即第一终端在接收到第二信息或者确定第二终端接入到第二小区时,可以恢复到非直连路径的数据和/或消息的传输。
本申请实施例中第一终端接入到第一小区可以包括以下任意一项:
第一终端向第一小区发起随机接入过程,如随机接入信道(Random Access Channel,RACH)过程,并确定随机接入成功;
第一终端随机接入成功,并向第一小区发送第一消息,可选的,第一消息可以是RRC重配置完成消息;
第一终端确定第一消息发送成功。
应用本申请实施例所提供的方法,第一终端通过至少两条路径与第一网络侧设备连接,至少两条路径包括一条直连路径,以及至少一条通过至少一个第二终端连接的非直连路径,第一终端从第一网络侧设备接收到第一信息后,根据该第一信息,对目标路径执行路径挂起操作,该目标路径为至少两条路径中的部分或全部路径,在满足第一条件的情况下,第一终端对目标路径执行路径恢复操作。也就是说第一终端与第一网络侧设备之间建立的多路径不会被断开,而只是对部分或全部路径执行路径挂起操作,在满足第一条件时,再对挂起的目标路径执行路径恢复操作,这样,第一终端不会断开与第二终端的连接,目标路径没有被释放,被挂起的目标路径在被恢复后,仍可在目标路径上继续进行数据和/或消息的传输,有效保证了业务连续性。
在本申请的一些实施例中,第一信息可以包括以下至少一项内容:
路径挂起指示信息;
第一小区的同步重配置信息;
第一小区的标识信息;
第二小区的同步重配置信息;
第二小区的标识信息,如NCGI。
其中,第一小区为第一终端要切换到的目标小区,第二小区为第二终端要切换到的目标小区,第一小区和第二小区在同一个网络侧设备的控制下。比如,第一小区和第二小区为第一网络侧设备的小区,第一终端和第二终端要在第一网络侧设备内进行小区切换,再比如,第一小区和第二小区为第二网络侧设备的小区,第一终端和第二终端要在网络侧设备之间进行小区切换,从第一网络侧设备的小区切换到第二网络侧设备的小区。
在本申请实施例中,第一信息可以包括路径挂起(suspend/suspension)指示信息, 或者称为路径激活(deactivate/deactivation)指示信息。路径挂起指示信息用于指示挂起多路径传输。第一终端接收到第一信息后,即可根据第一信息包括的路径挂起指示信息,对目标路径执行路径挂起操作。目标路径可以包括直连路径和/或至少一条非直连路径。即第一终端可以挂起向直连路径和/或至少一条非直连路径的数据和/或消息的传输。向至少一条非直连路径的数据和/或消息的传输也即为到至少一个第二终端的终端间的数据和/或消息的传输。在旁链路中继架构下,终端间的数据和/或消息的传输也即为基于PC5relay RLC channel的数据和/或消息的传输。
第一信息可以包括第一小区的同步重配置信息和/或第一小区的标识信息,第一终端接收到第一信息,对目标路径执行路径挂起操作后,可以向第一小区发起随机接入过程,在随机接入成功后,第一终端可以向第一小区发送第一消息。随机接入过程可以是RACH过程。第一消息可以为RRC重配置完成消息。如果第一小区为第一网络侧设备的小区,则第一终端是向第一网络侧设备发送第一消息,如果第一小区为第二网络侧设备的小区,则第一终端是向第二网络侧设备发送第一消息。
第一终端在随机接入成功,或者向第一小区发送第一消息,或者在确定第一消息发送成功后,可以自主恢复向直连路径的数据和/或消息的传输,或者在接收到第一网络侧设备或者第二网络侧设备发送的路径恢复指示信息时恢复向直连路径的数据和/或消息的传输。
第一信息可以包括第二小区的同步重配置信息和/或第二小区的标识信息,第二小区的同步重配置信息和/或第二小区的标识信息是给第二终端的信息,第一终端接收到第一信息,对目标路径执行路径挂起操作之后,还可以执行以下至少一项:
1)第一终端可以向第二终端发送第一通知信息,该第一通知信息用于挂起第二终端对应的无线链路控制通道或非直连路径的数据和/或消息的传输。其中,数据的传输可以是承载在数据无线承载(Data radio bearer,DRB)上的传输,消息的传输可以是承载在信号无线承载(Singnalling radio bearer,SRB)上的传输,无线链路控制通道或非直连路径可以是专门为第一终端提供数据中转服务的无线空口,如Uu中继无线链路控制信道(Uu relay RLC channel)或Uu中继无线链路控制承载(Uu Relay RLC bearer),二者的区别在于是否需要适配层(adaptation layer)进行中转处理;
2)第一终端可以向第二终端发送第二小区的同步重配置信息和/或第二小区的标识信息。即将第二小区的同步重配置信息和/或第二小区的标识信息转发给第二终端,以使第二终端能够接入到第二小区。
第一网络侧设备将相关信息发送给第一终端,方便通过第一终端保证按照第一终端、第二终端的先后时序进行切换,保证切换后多路径能够正常进行数据和/或消息的传输。
在本申请的一些实施例中,在满足以下任意一项的情况下,第一终端可以向第二终端发送第一通知信息和/或向第二终端发送第二小区的同步重配置信息和/或第二小区的标识信息:
第一终端向第一小区发起随机接入过程,并确定随机接入成功;
第一终端随机接入成功,并向第一小区发送第一消息;
第一终端确定第一消息发送成功。
也就是说,第一终端在向第一小区发起随机接入过程,并确定随机接入成功时,可以向第二终端发送第一通知信息和/或向第二终端发送第二小区的同步重配置信息和/或第二小区的标识信息;或者,第一终端在向第一小区发起随机接入过程,随机接入成功,并向第一小区发送第一消息时,可以向第二终端发送第一通知信息和/或向第二终端发送第二小区的同步重配置信息和/或第二小区的标识信息;或者,第一终端在向第一小区发起随机接入过程,随机接入成功,向第一小区发送第一消息,并确定第一消息发送成功时,可以向第二终端发送第一通知信息和/或向第二终端发送第二小区的同步重配置信息和/或第二小区的标识信息。这样可以保证在第一终端已经接入到第一小区的情况下,第二终端进行小区切换,保证切换后多路径可以顺利进行数据和/或消息的传输。
需要说明的是,第一信息中包括的多项内容可以是通过同一消息或信令传输的,如都是通过RRC重配置消息传输。第一信息中包括的多项内容还可以是通过不同消息或信令传输的,比如,路径挂起指示信息是通过MAC CE信令传输的,第一小区的同步重配置信息、第一小区的标识信息、第二小区的同步重配置信息、第二小区的标识信息是通过RRC重配置消息传输的。
另外需要说明的是,如果第一信息显示包括路径挂起指示信息,则第一终端在接收到第一信息,并确定第一信息中包括了路径挂起指示信息时,可以对目标路径执行路径挂起操作。如果第一信息未显示包括路径挂起指示信息,则第一终端可以基于第一信息中包括的其他内容,如第一小区的同步重配置信息、第一小区的标识信息、第二小区的同步重配置信息、第二小区的标识信息,以及第一终端支持多路径到多路径切换的能力信息,隐式确定需要对目标路径执行路径挂起操作,进而对目标路径执行路径挂起操作。
再有需要说明的是,在第一终端和第二终端在同一网络侧设备内的不同小区间切换的情况下,第二终端接入第二小区与第一终端对目标路径执行路径恢复操作的执行先后顺序可以通过第一网络侧设备控制,例如,第一网络侧设备在确定第二终端随机接入成功或者接收到第二终端发送的第二消息后,再向第一终端发送第二信息,指示第一终端对目标路径执行路径恢复操作。在第一终端和第二终端在不同网络侧设备的小区间切换的情况下,第二终端接入第二小区与第一终端对目标路径执行路径恢复操作的执行先后顺序可以通过第二网络侧设备控制,例如,第二网络侧设备在确定第二终端随机接入成功或者收到第二终端发送的第二消息,如RRC重配置完成消息后,再向第一终端发送第二信息,指示第一终端对目标路径执行路径恢复操作。
在本申请的一些实施例中,在目标路径包括非直连路径的情况下,在第一终端对目标路径执行路径恢复操作之后,该方法还可以包括以下步骤:

2)Remote UE的目标小区的同步重配置信息;在本示例中,Remote UE的当前服务小区为gNB1控制下的一个小区,如cell 1,目标小区为gNB1控制下的另一个小区,如cell 2;
3)Remote UE的目标小区的标识信息,如NR小区全球标识符(NR Cell Global Identifier,NCGI);
4)给Relay UE使用的RRC重配置消息2,该RRC重配置消息2携带了Relay UE的目标小区的同步重配置信息和/或Relay UE的目标小区的标识信息,如NCGI;在本示例中,Relay UE的当前服务小区为gNB1控制下的一个小区,如cell 1,目标小区为gNB1控制下的另一个小区,如Cell 2或Cell 3,即Remote UE和Relay UE的目标小区可以相同或者不同,取决于基站配置。
步骤2:Remote UE根据步骤1中的RRC重配置消息1,执行以下至少一项行为:

2)挂起向直连路径的数据和/或消息的传输。
需要说明的是,RRC重配置消息1中可以显式引入路径挂起指示信息,Remote UE在判断RRC重配置消息1携带了路径挂起指示信息的情况下,执行上述行为,或者,RRC重配置消息1中未引入路径挂起指示信息,Remote UE可以通过RRC重配置消息1中携带的其他内容,如Remote UE的目标小区的同步重配置信息、Remote UE的目标小区NCGI,给Relay UE使用的RRC重配置消息2中的至少之一和/或Remote UE的能力,如支持MP-to-MP切换,隐式推导出需要执行上述行为,继而执行上述行为。

需要说明的是,步骤3和步骤4涉及两个不同的执行主体,步骤3由Relay UE执行,而步骤4由Remote UE执行,因此,步骤3和步骤4执行先后顺序可以由基站gNB1控制,例如,基站gNB1在确认步骤3中的RACH成功或者收到步骤3中的RRC重配置完成消息之后,才会给Remote UE发送RRC重配置消息3,以触发Remote UE执行步骤4。
步骤5:Remote UE根据步骤4中的RRC重配置消息3,执行以下至少一项行为:

步骤5-1:Remote UE根据步骤4中的RRC重配置消息3,执行以下行为:

在示例一中,如果Remote UE具有自主恢复能力,则Remote UE在执行步骤2-1之后,可以自主恢复向直连路径的数据和/或消息的传输。在这种情况下,Remote UE在执行步骤5时,执行的行为可以不包括恢复向直连路径的数据和/或消息的传输。
同样,如果Relay UE具有自主恢复能力,则Relay UE在执行步骤3之后,可以自主恢复到Uu relay RLC channel或者Uu relay RLC bearer的数据和/或消息的传输。在这种情况下,Remote UE可以不执行步骤5-1。

路径恢复指示信息,或称为路径激活指示信息。
需要说明的是,步骤3和步骤4涉及两个不同的执行主体,步骤3由Relay UE执行,而步骤4由Remote UE执行,因此,步骤3和步骤4执行先后顺序可以由基站gNB2控制,例如,基站gNB2在确认步骤3中的RACH成功或者收到步骤3中的RRC重配置完成消息之后,才会给Remote UE发送RRC重配置消息3,以触发Remote UE执行步骤4。

向Remote UE的目标小区发起RACH过程,并在RACH成功后,向Relay UE的目标小区发送RRC重配置完成消息。在该示例下,Remote UE的目标小区为gNB2控制下的另一个小区,如cell 2,即Remote UE将RRC重配置完成消息发送给gNB2。
进一步地,在执行步骤4a之后,Remote UE可以自主恢复到Relay UE的UE间数据和/或消息的传输,和/或向直连路径的数据和/或消息的传输。
在示例四中,如果Remote UE和/或Relay UE不具有自主恢复能力,则Relay UE在执行步骤3b之后,不自主恢复到Uu relay RLC channel或者Uu relay RLC bearer的数据和/或消息的传输,而是在接收到gNB2发送的RRC重配置消息4时,执行恢复操作,即恢复到Uu relay RLC channel或者Uu relay RLC bearer的数据和/或消息的传输。同样,Remote UE在执行步骤4a之后,不自主恢复到Relay UE的UE间数据和/或消息的传输,和/或向直连路径的数据和/或消息的传输,而是在接收到gNB2发送的RRC重配置消息5时,执行恢复操作,即恢复到Relay UE的UE间数据和/或消息的传输,和/或向直连路径的数据和/或消息的传输。gNB2可以在接收到Relay UE发送的重配置完成消息的情况下向Relay UE发送RRC重配置消息4,可以在接收到Remote UE发送的重配置完成消息的情况下向Remote UE发送RRC重配置消息5。
另外,对步骤1a和步骤1b的执行顺序不做限制,即gNB1可以先向Remote UE发送RRC重配置消息1,再向Relay UE发送RRC重配置消息2,或者,先向Relay UE发送RRC重配置消息2,再向Remote UE发送RRC重配置消息1,或者,同时向Remote UE发送RRC重配置消息1,向Relay UE发送RRC重配置消息2。
