技术领域
本申请属于通信技术领域，具体涉及一种中继的配置方法、装置及用户设备。
背景技术
无线通信系统中的中继(relay)技术，是在基站与用户设备(user equipment，UE)之间增加了一个或多个中继节点，负责对无线信号进行一次或者多次的转发，即无线信号要经过多跳才能到达UE，例如UE到网络侧的中继(UE-to-network relay)，即中继设备一端连接UE，一端连接网络设备，与中继设备连接的UE称为远端(remote)UE。然而在中继场景中，基站如何向远端UE发送某些必要的数据(例如无线资源控制(radio resource control，RRC)配置)是亟待解决的问题。
发明内容
本申请实施例的目的是提供一种中继的配置方法、装置及用户设备，能够解决基站如何向远端UE发送某些必要的数据的问题。
为了解决上述技术问题，本申请是这样实现的：
第一方面，本申请实施例提供了一种中继的配置方法，该中继的配置方法包括：UE根据目标信息，获取中继相关配置信息。其中，目标信息包括以下至少一项：第一信息和第二信息，该第一信息用于指示UE是否处于远端设备的直接覆盖范围内，该第二信息用于指示UE是否与远端设备连接，中继相关配置信息用于UE进行中继相关通信，远端设备为UE的远端UE或网络设备。
第二方面，本申请实施例提供了一种中继的配置装置，该中继的配置装置包括：获取模块。获取模块，用于根据目标信息，获取中继相关配置信息。其中，目标信息包括以下至少一项：第一信息和第二信息，该第一信息用于指示UE是否处于远端设备的直接覆盖范围内，该第二信息用于指示UE是否与远端设备连接，中继相关配置信息用于UE进行中继相关通信，远端设备为UE的远端UE或网络设备。
第三方面，本申请实施例提供了一种UE，该UE包括处理器、存储器及存储在所 述存储器上并可在所述处理器上运行的程序或指令，所述程序或指令被所述处理器执行时实现如第一方面所述的中继的配置方法的步骤。
第四方面，本申请实施例提供了一种可读存储介质，所述可读存储介质上存储程序或指令，所述程序或指令被处理器执行时实现如第一方面所述的中继的配置方法的步骤。
第五方面，本申请实施例提供了一种芯片，所述芯片包括处理器和通信接口，所述通信接口和所述处理器耦合，所述处理器用于运行程序或指令，实现如第一方面所述的中继的配置方法。
在本申请实施例中，UE可以根据目标信息(UE是否处于远端设备的直接覆盖范围内，和/或，UE是否与远端设备连接)，获取中继相关配置信息。由于在中继场景中，UE可以根据UE与远端设备的直接覆盖范围的关系，和/或，UE与远端设备的连接关系，以准确地获得需要的中继相关配置信息，从而进行中继相关通信，而并非直接从中继设备或远端UE接收中继相关配置信息，因此提高了UE获取中继相关配置信息的灵活性和准确性。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面对本申请实施例提供的中继的配置方法、装置及用户设备中涉及的一些概念和/ 或术语做一下解释说明。
1、副链路(sidelink)：也可以称为侧链路或边链路等。在长期演进(long term evolution，LTE)系统中支持sidelink，该sidelink用于UE与UE之间不通过网络设备直接进行数据传输。
LTE sidelink的设计适用于特定的公共安全事务(例如火灾场所或地震等灾难场所进行紧急通讯)，或者车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE sidelink只支持广播通信，因此主要用于基本安全类通信，其他在时延、可靠性等方面具有严格QoS需求的高级V2X业务将通过NR sidelink支持。
5G NR系统可用于LTE所不支持的6GHz以上工作频段，支持更大的工作带宽，但目前版本的NR系统只支持基站与终端间的接口，尚不支持终端之间直接通信的sidelink接口。sidelink的链路接口可以称为PC5接口。
2、中继(relay)机制：无线通信系统中的中继技术，就是在基站与终端之间增加了一个或多个中继节点，负责对无线信号进行一次或者多次的转发，即无线信号要经过多跳才能到达终端。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。例如以两跳中继为例，无线中继就是将一个基站—UE的链路分割为基站—中继站和中继站—UE两个链路，从而有机会将一个质量较差的链路替换为两个质量较好的链路，以获得更高的链路容量及更好的覆盖。目前LTE中支持的中继为UE-to-network relay，即中继一端连接UE，一端连接网络侧。跟中继连接的UE，叫做远端(remote)UE。中继UE与基站之间是Uu接口，中继UE和远端UE之间是sidelink接口。通常中继UE是开放的，可以为任何远端UE服务。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(long term evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(code division multiple access，CDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multiple access，FDMA)、正交频分多址(orthogonal frequency division multiple access，OFDMA)、单载波频分多址(single-carrier frequency-division multiple access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(new radio，NR)系统，并且在以下大部分描述中使用NR术语，这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
示例性的，图1示出了本申请实施例提供的一种通信系统的架构示意图。如图1所示，该通信系统可以包括UE 01和网络设备02。其中，UE 01与网络设备02之间可以建立连接并通信。
本申请实施例中的UE也可以称作终端设备，UE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)、可穿戴式设备(wearable device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定UE的具体类型。
本申请实施例中的网络设备可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(base transceiver station，BTS)、无线电基站、无线电收发机、基本服务集(basic service set，BSS)、扩展服务集(extended service set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(transmitting receiving point，TRP)或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的中继的配置方法进行详细地说明。
本申请实施例中，在中继场景中，remote UE可能位于基站本身的覆盖范围外，但是可以通过relay UE与基站进行连接，在这种情况下，本申请提供了基站是否可以通过relay UE中转来为remote UE进行一些必要的无线资源配置的方案。或者，remote UE可能位于基站本身的覆盖范围内，或从覆盖范围外进入覆盖范围内，在这种情况下，本申请也提供了基站是否应该直接发送配置给remote UE还是应该通过relay UE中转来为remote UE进行一些必要的无线资源配置的方案。
本申请实施例的方案适用于L2架构和L3架构，也适用于UE-to-network relay架构和UE-to-UE relay架构。
其中，L3架构的特点：relay UE具有完整的协议栈，即除了无线链路层控制协议(radio link control，RLC)、介质访问控制子层协议(media access control，MAC)和物理层协议(physical，PHY)这些基本的L2传输协议栈以外，也具有无线资源控制层(radio resource control，RRC)、服务数据适配协议(service data adaptation protocol，SDAP)和分组数据汇聚协议(packet data convergence protocol，PDCP)等协议栈，用于对remote UE的数据进行承载和传输。对于UE-to-UE relay架构，remote UE 1与relay UE之间有完整的协议栈， relay UE与remote UE 2之间也有完整的协议栈；对于UE-to-network relay架构，remote UE与relay UE之间有完整的协议栈，relay UE与基站之间也有完整的协议栈。
L2架构的特点：relay UE对其中继的数据并不具有完整的协议栈，即除了RLC、MAC和PHY这些基本的L2传输协议栈以外，并没有对应的RRC、SDAP和PDCP等协议栈，只用RLC对remote UE的数据进行承载和传输。对于UE-to-network relay架构，remote UE和基站之间具有对等的RRC、SDAP和PDCP等协议栈，而remote UE与relay UE之间仅有RLC层及以下协议栈，relay UE与基站之间也仅有RLC层及以下协议栈；对于UE-to-UE relay架构，remote UE1和remote UE 2之间具有对等的RRC、SDAP和PDCP等协议栈，而remote UE1与relay UE之间仅有RLC层及以下协议栈，relay UE与remote UE 2之间也仅有RLC层及以下协议栈。
另外，不论是L2架构、L3架构，还是UE-to-network relay、UE-to-UE relay，在remote UE、relay UE和基站处，都可以还有额外的适配层(adaption layer)，本申请实施例对协议栈不作限制。

步骤201、UE获取目标信息。
步骤202、UE根据目标信息，获取中继相关配置信息。
本申请实施例中，上述目标信息包括以下至少一项：第一信息和第二信息，第一信息用于指示UE是否处于远端设备的直接覆盖范围内，第二信息用于指示UE是否与远端设备连接，上述中继相关配置信息用于UE进行中继相关通信，远端设备为UE的远端UE或网络设备。
需要说明的是，本申请实施例中的UE可以理解为中继通信中的remote UE，远端设备为可以为该UE对端的remote UE，即UE-to-UE relay架构下，与该UE通过relay连接的对端的remote UE。
可选地，本申请实施例中，上述中继相关配置信息可以为RRC信令发送的(RRC相关配置信息)，或者也可以是MAC CE发送的，或者还可以是预配置的。
需要说明的是，本申请实施例中，远端设备的直接覆盖范围外(例如基站的直接覆盖范围外)，可以理解为：remote UE无法直接接收到基站的广播消息或RRC专用信令，那么remote UE在基站的直接覆盖范围外。并且，如果此时remote UE通过relay UE连接上了基站，可以接收到基站的广播消息或RRC专用信令，这种情况可以称为“在基站的直接覆盖范围外，但是通过relay连接上了基站”，当然，这种情况是否可以称为在基站的 覆盖范围内，本申请实施例不作限制。远端设备的直接覆盖范围内(例如基站的直接覆盖范围内)，可以理解为：remote UE可以直接接收到基站的广播消息或RRC专用信令，那么remote UE在基站的直接覆盖范围内。
可选地，本申请实施例中，上述步骤201具体可以通过下述的步骤201a、步骤201b或步骤201c实现。
步骤201a、UE根据目标信息，接收目标设备发送的中继相关配置信息。
本申请实施例中，上述目标设备包括以下至少一项：中继设备和远端设备。
需要说明的是，本申请实施例中，UE接收目标设备发送的中继相关配置信息可以理解为：UE从目标设备接收中继相关配置信息，即UE可以仅从中继设备接收中继相关配置信息，并且无法从远端设备接收中继相关配置信息；或者，UE可以仅从远端设备接收中继相关配置信息，并且无法从中继设备接收中继相关配置信息；或者，UE可以从中继设备和远端设备均接收中继相关配置信息，但每一次配置接收过程实际的中继相关配置信息只会来自于中继设备或只会来自于远端设备；或者，UE可以从中继设备和远端设备均接收中继相关配置信息，且每一次配置接收过程相关配置信息会同时来自于中继设备和远端设备。另外，UE从中继设备接收中继相关配置信息可以理解为：中继相关配置信息可以是中继设备直接发送的(即来自于中继设备本身)，或者中继相关配置信息可以是中继设备转发的远端设备发送的。
步骤201b、UE根据目标信息和第一指示信息，接收目标设备发送的中继相关配置信息。
本申请实施例中，上述第一指示信息用于目标设备指示中继相关配置信息的发送方式。
需要说明的是，中继相关配置信息的发送方式可以理解为：中继相关配置信息是由远端设备直接发送的，或者是由中继设备直接发送的，或者是由中继设备转发的(即远端设备发送给中继设备，中继设备再发送给UE)。
可选地，本申请实施例中，对于L2架构，remote UE位于基站的直接覆盖范围内，若该remote UE已经通过relay UE连接到了基站，该remote UE可以基于基站的指示(即第一指示信息)，以确定从哪个设备处接收中继相关配置信息以及该remote UE的数据面数据的传输方式，即确定中继相关配置信息(和/或数据面数据)来自于remote UE直接的Uu接口或通过relay中转。
需要说明的是，上述第一指示信息可以为目标设备发送的，上述中继相关配置信息也可以是目标设备发送的，发送第一指示信息的设备与发送中继相关配置信息的设备相同或者不同。例如，第一指示信息可以是远端设备发送给UE的，以指示UE从中继设备接收 中继相关配置信息。或者，第一指示信息可以是中继设备发送给UE的，以指示UE从远端设备接收中继相关配置信息。
步骤201c、UE根据目标信息，获取预定义、预配置或协议约定的中继相关配置信息。
需要说明的是，针对UE接收目标设备发送的中继相关配置信息，或者获取预定义、预配置或协议约定的中继相关配置信息的具体方法，将在下述实施例中进行描述，此处不予赘述。
可选地，在本申请实施例的一种实现方式中，上述步骤201具体可以通过下述的步骤201d或步骤201e实现。

步骤201e、在UE处于远端设备的直接覆盖范围外、且UE通过中继设备与远端设备连接的情况下，UE获取预定义、预配置或协议约定的中继相关配置信息。
可选地，本申请实施例中，上述中继相关配置信息的获取方式由以下任一项确定：第二指示信息、UE和协议约定。其中，第二指示信息用于远端设备指示中继相关配置信息的获取方式。
需要说明的是，在UE处于远端设备的直接覆盖范围外、且UE通过中继设备与远端设备连接的情况下，UE是执行上述201d还是执行上述步骤201e，可以由第二指示信息确定，或者由UE自身决定，或者由协议约定。
示例性的，对于L2架构，若remote UE位于基站的直接覆盖范围外，且remote UE通过relay UE连接到基站，由于remote UE与基站之间具有对等的RRC，SDAP和PDCP等协议栈，此时基站可以通过relay UE中转，为remote UE进行RRC无线资源配置及相关参数配置。这里的RRC无线资源配置及相关参数配置可以是基站以系统消息的形式发送给relay UE，再由relay UE发送给remote UE，或者是以RRC专用信令的方式发送给relay UE，再由relay UE发送给remote UE。其中，relay UE发送给remote UE时，relay UE可以用广播、组播或单播的方式发送给remote UE。
又示例性的，对于L3架构，若remote UE位于基站的直接覆盖范围外，且remote UE通过relay UE连接到基站，UE可以使用预配置(出厂预配置或基站预配置)的中继相关配置信息，或者，基站可以通过relay UE中转，为remote UE进行RRC无线资源配置及相关参数配置。
可选地，在本申请实施例的另一种实现方式中，上述步骤201具体可以通过下述的步骤201f或步骤201g实现。
步骤201f、在UE处于远端设备的直接覆盖范围外、且UE与远端设备未连接的情况 下，在UE与中继设备建立连接之后，UE接收中继设备发送的中继相关配置信息。
示例性的，对于L2架构，若remote UE位于基站的直接覆盖范围外，且remote UE还未通过relay UE连接到基站，此时remote UE可以通过查找过程找到relay UE并建立连接，等待后续基站通过relay UE为remote UE进行RRC无线资源配置及相关参数配置。
又示例性的，对于L3架构，若remote UE位于基站的覆盖范围外，且remote UE还未通过relay UE连接到基站，此时remote UE可以使用预配置的中继相关配置信息。
步骤201g、在UE处于远端设备的直接覆盖范围外、且UE与远端设备未连接的情况下，UE获取预定义、预配置或协议约定的中继相关配置信息。
可选地，本申请实施例中，上述步骤201d(或步骤201f)中的“UE接收中继设备发送的中继相关配置信息”具体可以通过下述的步骤201d1或步骤201d2实现。
步骤201d1、UE接收中继设备发送的系统消息，该系统消息中包括中继相关配置信息。
步骤201d2、UE接收中继设备发送的RRC专用信令，该RRC专用信令中包括中继相关配置信息。
可以理解，远端设备可以以系统消息的形式，将中继相关配置信息发送给relay UE，再由relay UE发送给remote UE，或者远端设备可以以RRC专用信令的方式，将中继相关配置信息发送给relay UE，再由relay UE发送给remote UE。
可选地，在本申请实施例的又一种实现方式中，上述步骤201具体可以通过下述的步骤201h实现。
步骤201h、在UE处于远端设备的直接覆盖范围内、且UE通过中继设备与远端设备连接的情况下，UE接收目标设备发送的中继相关配置信息。
需要说明的是，UE处于远端设备的直接覆盖范围内可以理解为：UE一直处于远端设备的直接覆盖范围内，或者也可以是UE由远端设备的直接覆盖范围外进入到远端设备的直接覆盖范围内。
可选地，本申请实施例中，基站可以将中继相关配置信息发送给relay UE，再由relay UE转发给remote UE，而remote UE不再通过自己的Uu接口从基站处获得中继相关配置信息。例如此时remote UE不会因为relay通信发起RRC连接建立过程；如果触发了链路切换，切换到了与基站之间的直接链路(direct link)，那么后续的中继相关配置信息可以由基站直接发送给remote UE。
可选地，本申请实施例中，在上述步骤201h中的“UE接收目标设备发送的中继相关配置信息”之前，本申请实施例提供的中继的配置方法还包括下述的步骤301、步骤302或步骤303。
步骤301、UE断开与中继设备的连接。
步骤302、UE直接与远端设备建立连接。
步骤303、UE断开与中继设备的连接，并直接与远端设备建立连接。
可以理解，在UE处于远端设备的直接覆盖范围内、且UE通过中继设备与远端设备连接的情况下，UE可以先主动断开与中继设备的连接，然后再从目标设备接收中继相关配置信息；和/或，UE可以先主动与远端设备建立连接，然后再从目标设备接收中继相关配置信息。
需要说明的是，UE断开与中继设备的连接之后，UE与中继设备之间无法单播或专有连接进行数据(例如中继相关配置信息和/或数据面数据)的发送和接收，但是在中继设备与UE之间支持组播或广播形式的数据的发送和接收的情况下，UE也可以通过中继设备进行数据的传输。
可选地，本申请实施例中，上述步骤201h中的“UE接收目标设备发送的中继相关配置信息”具体可以通过下述的步骤201h1或步骤201h2实现。
步骤201h1、在中继相关配置信息为中继相关业务对应的配置信息的情况下，UE接收中继设备发送的中继相关配置信息。
步骤201h2、在中继相关配置信息为非中继相关业务对应的配置信息的情况下，UE接收远端设备发送的中继相关配置信息。
可以理解，remote UE的中继相关配置信息来自于relay UE中转或是直接的Uu接口(即直接从基站接收)，取决于中继相关配置信息的具体内容。具体的，若中继相关配置信息是用于非relay相关的业务，则中继相关配置信息可以来自于Uu接口，如果中继相关配置信息是用于relay相关的业务，则中继相关配置信息来自于relay UE中转。
可选地，本申请实施例中，上述步骤201h中的“UE接收目标设备发送的中继相关配置信息”具体可以通过下述的步骤201h3实现。
步骤201h3、UE接收中继设备发送的RRC专用信令，并接收远端设备发送的系统消息，该RRC专用信令和系统消息中均包括中继相关配置信息。

可选地，本申请实施例中，在上述步骤201h之后，本申请实施例提供的中继的配置方法还包括下述的步骤401。
步骤401、UE通过目标设备发送或接收UE的数据面数据。
需要说明的是，UE通过目标设备发送或接收UE的数据面数据可以理解为：UE向目标设备发送UE的数据面数据，或者，UE从目标设备接收数据面数据。
需要说明的是，中继相关配置信息和数据面数据可以来自于同一条链路(直接的Uu 接口或Relay中转)，也可以来自于不同的链路，即UE可以从中继设备接收中继相关配置信息，并通过中继设备发送或接收数据面数据；或者，UE可以从中继设备接收中继相关配置信息，并通过远端设备发送或接收数据面数据；或者，UE可以从远端设备接收中继相关配置信息，并通过远端设备发送或接收数据面数据；或者，UE可以从远端设备接收中继相关配置信息，并通过中继设备发送或接收数据面数据。
可选地，本申请实施例中，上述步骤401具体可以通过下述的步骤401a、步骤401b或步骤401c实现。
步骤401a、在UE与中继设备断开连接的情况下，UE通过目标设备发送或接收UE的数据面数据。
步骤401b、在UE与远端设备直接建立连接的情况下，UE通过目标设备发送或接收UE的数据面数据。
步骤401c、在UE断开与中继设备的连接，并与远端设备直接建立连接的情况下，UE通过目标设备发送或接收UE的数据面数据。
需要说明的是，在执行上述步骤301(或步骤302、或步骤303)之后，UE可以执行上述步骤201h中的“UE接收目标设备发送的中继相关配置信息”和步骤401，即在UE处于远端设备的直接覆盖范围内、且UE通过中继设备与远端设备连接的情况下，UE可以先主动断开与中继设备的连接，然后再从目标设备接收中继相关配置信息，并通过目标设备发送或接收UE的数据面数据；和/或，UE可以先主动与远端设备建立连接，然后再从目标设备接收中继相关配置信息，并通过目标设备发送或接收UE的数据面数据。
示例性的，在UE处于远端设备的直接覆盖范围内、且UE通过中继设备与远端设备连接的情况下，remote UE断开了与relay UE的连接，此时remote UE可以与基站直接通过Uu接口进行通信，例如从基站接收中继相关配置信息，并与基站传输数据面数据。
又示例性的，在UE处于远端设备的直接覆盖范围内、且UE通过中继设备与远端设备连接的情况下，remote UE继续通过relay UE连接到基站，此时remote UE可以直接通过Uu接口从基站接收中继相关配置信息，并通过中继设备与基站之间进行数据面数据的传输。
可选地，本申请实施例中，在上述步骤401之前，本申请实施例提供的中继的配置方法还包括下述的步骤501、步骤502或步骤503。

可以理解，在UE处于远端设备的直接覆盖范围内、且UE通过中继设备与远端设备 连接的情况下，UE从目标设备接收中继相关配置信息，然后主动断开与中继设备的连接，再通过目标设备发送或接收UE的数据面数据；和/或，UE从目标设备接收中继相关配置信息，然后主动与远端设备建立连接，再通过目标设备发送或接收UE的数据面数据。
可选地，在本申请实施例的又一种实现方式中，上述步骤201具体可以通过下述的步骤201i实现。
步骤201i、在UE处于远端设备的直接覆盖范围内、且UE与远端设备未直接连接的情况下，UE接收中继设备或远端设备发送的系统消息，系统消息中包括中继相关配置信息。
本申请实施例中，remote UE的中继相关配置信息来自于中继设备中转或者直接的远端设备，取决于remote UE与远端设备的直接连接状态，以及remote UE通过中继设备与远端设备的连接状态。
一种方式中，若remote UE与远端设备有直接的RRC连接(例如由于relay业务或有其他业务/原因，触发了RRC连接建立，或者触发了从中继中转链路到直连链路的切换)，那么中继相关配置信息来自于直接的远端设备。
另一种方式中，若remote UE与远端设备没有直接的RRC连接，但是通过中继设备连接到远端设备，则中继相关配置信息来自于中继设备中转，或者UE可以从中继设备接收专用RRC无线资源配置及相关参数配置，并读取基站的系统消息来获得广播的RRC无线资源配置及相关参数配置。
又一种方式中，若remote UE与远端设备没有直接的RRC连接，也没有通过中继设备连接到远端设备(如remote与中继设备之间不存在PC5-RRC连接，或中继设备处于RRC空闲(idle)态或非激活(inactive)态)，那么remote UE可以通过Uu接口读取远端设备的系统消息，来获得广播的RRC无线资源配置及相关参数配置，或者remote UE可以通过中继设备中转远端设备的系统消息来获得广播的RRC无线资源配置及相关参数配置。
示例性的，对于L3架构，remote UE位于基站的覆盖范围内，remote UE可以从自己的Uu接口来获得RRC无线资源配置及相关参数配置。具体的，由RRC连接状态来确定获取系统消息或者专用的中继相关配置信息，例如idle态或inactive态时获取系统消息，连接(connected)态时获取专用的RRC无线资源配置及相关参数配置。
本申请实施例提供一种中继的配置方法，UE可以根据目标信息(UE是否处于远端设备的直接覆盖范围内，和/或，UE是否与远端设备连接)，获取中继相关配置信息。由于在中继场景中，UE可以根据UE与远端设备的直接覆盖范围的关系，和/或，UE与远端设备的连接关系，以准确地获得需要的中继相关配置信息，从而进行中继相关通信，而并非直接从中继设备或远端UE接收中继相关配置信息，因此提高了UE获取中继相关配置信 息的灵活性和准确性。
下面通过具体的实施例(实施例一至实施例四)，对本申请实施例提供的中继的配置方法进行说明。
本申请实施例的方案适用于L2架构和L3架构，也适用于UE-to-network relay架构和UE-to-UE relay架构。
实施例一：L2架构，remote UE位于基站覆盖外
方案一：remote UE还未通过relay UE连接到基站：
此时remote UE必须通过discovery procedure等过程找到relay UE并建立连接，等待后续基站通过relay UE为remote UE进行RRC无线资源配置及相关参数配置。
方案二：remote UE通过relay UE连接到基站：
由于remote UE与基站之间具有对等的RRC，SDAP和PDCP等协议栈，此时基站通过relay UE中转，为remote UE进行RRC无线资源配置及相关参数配置。这里的RRC无线资源配置及相关参数配置可以是基站以系统消息的形式，或是以RRC专用信令的方式发送给relay UE，再由relay UE发送给remote UE。而relay UE发送给remote UE时，也可以用广播、组播、或单播的方式发送给remote UE。
实施例二：L2架构，remote UE位于基站覆盖内
此时，如果remote UE已经通过relay UE连接到了基站：
方式1：remote UE的RRC无线资源配置及相关参数配置仅来自于基站发送给relay UE再由relay UE转发给remote UE，而remote UE不再通过自己的Uu接口来从基站处获得RRC无线资源配置及相关参数配置。如，此时remote UE可能不会发起RRC连接建立过程。
方式2：remote UE的RRC无线资源配置及相关参数配置仅来自于基站直接通过Uu接口发送给remote UE。此时，又分两种情况：
方案1:remote UE可能会断开与relay UE的连接。即，此时remote UE倾向于与基站直接通过Uu接口进行通信，不仅包括RRC无线资源配置及相关参数配置，也包括数据面的数据。
方案2:remote UE可能继续通过relay UE连接到基站，此时remote UE的RRC无线资源配置及相关参数配置仅来自于基站直接通过Uu接口发送给remote UE，而remote UE的数据面的数据会通过relay UE与基站间进行传输。
方式3：remote UE的RRC无线资源配置及相关参数配置既可以来自于基站发送给relay UE再由relay UE转发给remote UE，也可以通过remote自己的Uu接口来从基站处获得RRC无线资源配置及相关参数配置。此时可以由基站自己决定配置从哪条路发给UE。 此时，又分两种情况：
方案1：remote UE的数据面的数据既可以通过relay UE中转来和基站间进行传输，也可以通过自remote自己的Uu接口来和基站进行数据的传输。
方案2：remote UE的数据面的数据会通过relay UE与基站间进行传输。
方式4：remote UE基于基站的指示，(该指示可以来自于relay UE中转，或来自于remote自己的Uu接口)，来确定采取如上方式1-方式3中的具体哪种方式来实现与基站间RRC无线资源配置及相关参数配置以及数据面数据的传输。
方式5：remote UE的RRC无线资源配置及相关参数配置来自于relay UE中转或是来自于直接的Uu接口，取决于RRC无线资源配置及相关参数配置的具体内容。例如，如果该RRC无线资源配置及相关参数配置是用于非relay相关的业务，那么就来自于Uu接口，如果是用于relay相关的业务，那么就来自于relay UE中转。
方式6：remote UE的RRC无线资源配置及相关参数配置来自于relay UE中转或是来自于直接的Uu接口，取决于remote UE与基站的连接状态，以及remote UE通过relay UE与基站进行连接的状态。如：
1、如果remote UE与基站有直接的RRC连接(如因为relay业务或有其他业务或原因触发了RRC连接建立，或者触发了从relay中转链路到直连链路的切换)，那么RRC无线资源配置及相关参数配置来自于直接的Uu接口。
2、如果remote UE与基站没有直接的RRC连接，但是通过relay UE直接连接到基站那么分两种情况：
a、RRC无线资源配置及相关参数配置来自于relay中转；
b、专用RRC无线资源配置及相关参数配置来自于relay中转，remote UE仍然可以读取基站的系统消息来获得广播的RRC无线资源配置及相关参数配置。
3、如果remote UE基站没有直接的RRC连接，也没有通过relay UE直接连接到基站(如remote与relay之间不存在PC5-RRC连接，或relay UE自己处于RRC-IDLE/INACTIVE态)，那么：
a、remote UE仅可以通过自己的Uu接口读取基站的系统消息来获得广播的RRC无线资源配置及相关参数配置；
b、remote UE仅可以通过relay UE中转基站的系统消息来获得广播的RRC无线资源配置及相关参数配置；
c、remote UE既可以用a也可以用b中的方式获得基站的系统消息来获得广播的RRC无线资源配置及相关参数配置。
实施例三：L3架构，remote UE位于基站覆盖外
方案1：remote UE还未通过relay UE连接到基站：
此时remote UE可以使用预配置(出厂预配置或基站预配置)。
方案2：remote UE通过relay UE连接到基站：
1、只能使用预配置
2、可以同实施例一中的case 2
3、既可以使用预配置，也可以同实施例一中的case 2。具体使用哪种可以基站指示或UE实现或协议约定。
实施例四：L3架构，remote UE位于基站覆盖内
1、仅基于remote UE自己的Uu接口来获得相关配置。具体的，由RRC连接状态来决定获取系统消息还是专用的配置(idle/inactive态使用系统消息，connected态使用专用的RRC无线资源配置及相关参数配置)。
2、采用上述实施例二中的各种方式来获得相关配置。
本申请的方案既可以用于UE-to-network relay架构，也可以用于UE-to-UE relay架构。(即上述实施例中的基站，可以替换为另一个remote UE)。通过本申请的方案可以使remote UE在不同的架构下，都可以准确地获得需要的RRC无线资源配置和相关参数配置。
需要说明的是，本申请实施例提供的中继的配置方法，执行主体可以为UE，或者中继的配置装置，或者该中继的配置装置中的用于执行加载中继的配置方法的控制模块。本申请实施例中以UE执行加载中继的配置方法为例，说明本申请实施例提供的中继的配置方法。

在一种可能的实现方式中，结合图3，如图4所示，本申请实施例提供的中继的配置装置30还包括：处理模块32。其中，处理模块32，用于在获取模块31接收目标设备发送的中继相关配置信息之前，断开与中继设备的连接；或者，直接与远端设备建立连接；或者，断开与中继设备的连接，并直接与远端设备建立连接。
在一种可能的实现方式中，上述获取模块31，具体用于在中继相关配置信息为中继相关业务对应的配置信息的情况下，接收中继设备发送的中继相关配置信息；在中继相关配置信息为非中继相关业务对应的配置信息的情况下，接收远端设备发送的中继相关配置信息。
在一种可能的实现方式中，上述获取模块31，具体用于接收中继设备发送的RRC专用信令，并接收远端设备发送的系统消息，该RRC专用信令和系统消息中均包括中继相关配置信息。
在一种可能的实现方式中，本申请实施例提供的中继的配置装置30还包括：传输模块。其中，传输模块，用于在获取模块31接收目标设备发送的中继相关配置信息之后，通过目标设备发送或接收UE的数据面数据。
在一种可能的实现方式中，上述传输模块，具体用于在UE与中继设备断开连接的情况下，通过目标设备发送或接收UE的数据面数据；或者，在UE与远端设备直接建立连接的情况下，通过目标设备发送或接收UE的数据面数据；或者，在UE断开与中继设备的连接，并与远端设备直接建立连接的情况下，通过目标设备发送或接收UE的数据面数 据。
在一种可能的实现方式中，结合图3，如图4所示，本申请实施例提供的中继的配置装置30还包括：处理模块32。其中，处理模块32，用于在传输模块通过目标设备发送或接收UE的数据面数据之前，断开与中继设备的连接；或者，直接与远端设备建立连接；或者，断开与中继设备的连接，并直接与远端设备建立连接。
在一种可能的实现方式中，上述获取模块31，具体用于在UE处于远端设备的直接覆盖范围内、且UE与远端设备未直接连接的情况下，接收中继设备或远端设备发送的系统消息，该系统消息中包括中继相关配置信息。
本申请实施例提供的中继的配置装置能够实现上述方法实施例中UE实现的各个过程，为避免重复，详细描述这里不再赘述。
