请参考图2，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图2所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(user equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基 站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实 施例不做限定。
本公开实施例涉及的执行主体包括但不限于：支持直连链路通信的终端等用户设备(UE，User Equipment)，以及蜂窝移动通信的基站等。
本公开实施例的应用场景为，当远端UE还未脱离基站无线网络覆盖范围时，远端UE可以向基站上报与一个或多个中继UE的直连链路无线信号测量结果，基站基于直连链路无线信号测量结果选择中继UE，然后将中继UE的标识发送给远端UE。UE在进行测量上报时，只会携带直连链路无线信号测量结果和直连链路UE标识，基站并不知道目标直连链路UE连接在哪个网络，因此在选择中继UE时，可能会选择连接在其他网络的中继UE，导致无法完成中继通信，或造成数据丢失。
如图3所示，本示例性实施例提供一种信息传输方法，无线通信系统的第一UE中，信息传输方法可以包括：
步骤301：接收一个或多个第二UE分别发送的与每个所述第二UE的网络状态相关联的网络信息；
步骤302：向基站发送一个或多个所述网络信息；
步骤303：接收所述基站发送的，指示所述一个或多个第二UE中的至少一个第二UE在第一工作状态下进行工作的指示信息。
步骤301中，第一UE可以是基于直连链路的中继通信时的远端UE，第二UE可以是直连链路中继通信中的备选的中继UE。一个或多个第二UE可以由第一UE从多个UE中选择的。第一UE可以从能与第一UE建立直连链路的UE中选择第二UE。网络信息所属的第二UE也可以是由基站指示的，基站可以向第一UE发送下行指令，指示网络信息所属的第二UE。
示例性的，第一UE可以基于在直连链路上接收到的广播信息确定可进行直连链路连接的UE，并将可进行直连链路连接的UE确定为备选的中继UE，即第二UE。
网络信息可以用于指示第二UE网络状态，如在线状态或离线状态等，网络信息可以包括：第二UE所属基站的标识信息、第二UE所在小区信息、和/或公共陆地移动(PLMN，Public Land Mobile Network)标识等。
网络信息还可以指示第二UE的网络连接状态，如第二UE处于空闲态、或非连接态等。基站或第一UE接收可以根据第二UE的网络连接状态后，可以通过发送指令等方式，指示第二UE改变当前的网络连接状态。例如，基站通过网络信息确定第二UE处于非连接态时，可以发送寻呼指令唤醒第二UE。
网络信息还可以指示第二UE的网络是否可以满足第二UE工作于第一工作状态的要求等。例如，网络信息可以指示第二UE当前的工作状态不满足第一工作状态的要求，基站接收到网络信息后，可以不指示该第二UE工作于第一工作状态。
发送给第二UE的指示信息可以由基站发送到第一UE，并由第一UE转发给第二UE；指示信息也可以由基站直接发送到第二UE，以指示所述至少一个第二UE在第一工作状态下进行工作。
第一工作状态可以包括中继工作状态等。在中继工作状态下第二UE可以作为中继UE中继基站和第一UE之间的通信。
第二UE可以通过广播等形式向第一UE发送网络信息。第一UE接收到一个或多个第二UE的网络信息后可以将网络信息发送给基站。这里，第一UE可以在RRC信息中携带网络信息发送给基站。RRC信息可以包括：SidelinkUEinformation、UEAssistanceInformation或measurementreport消息等。
基站在接收到一个或多个第二UE的网络信息，可以选择至少一个第二UE工作于第一工作状态下。例如，基站可以基于网络信息中标识信息，确定第二UE所连接的基站，当第二UE连接的基站与第一UE连接的基站相 同时，选择该第二UE工作于第一工作状态。使得第二UE可以在同一基站下进行中继通信，可以减少由于在不同通信网络下进行中继产生的通信繁复等情况。
示例性的，基站可以基于网络信息中第二UE所属小区的小区信息，确定第二UE所属小区，当第二UE所属小区处于基站覆盖范围，即基站可以利用该第二UE作为与第一UE的中继。如此，选择具备中继条件第二UE进行中继，提升通信质量。
以第一工作状态为中继工作状态为例，第一UE通过一个或多个第二UE的广播信息，接收一个或多个第二UE的网络信息；并将一个或多个第二UE的网络信息发送给基站，由基站确定中继工作的UE，并通过指示信息指示选择作为中继的第二UE。第一UE接收到指示信息后，可以将指示信息发送给选择的第二UE，指示选择的第二UE进行通信中继。在一个可选的实施例中，所述指示信息可以是与经选择的所述第二UE的标识相关联的信息，例如，经选择的所述第二UE的标识符等。在另一个可选的实施例中，所述指示信息可以由基站直接发送给经选择的所述第二UE，而所述指示信息可以是触发经选择的所述第二UE进入中继状态的触发指示。
如此，基站可以基于网络信息，选择工作于第一工作状态的第二UE。保证选择的第二UE的网络状态可以满足第一工作状态的需求，进而提高通信质量。
在一个实施例中，所述网络信息用于由所述基站在所述一个或多个第二UE中选择所述至少一个第二UE。
网络信息可以用于由基站确定进行中继的第二UE。基站可以选择与自身能建立通信的第二UE作为中继，减少出现基站与中继无法通信的情况。第一UE可以接收所述基站发送的，指示基站基于网络信息确定的所述一个或多个第二UE中的至少一个第二UE在第一工作状态下进行工作的指示信 息。
示例性的，网络信息可以用于表征一个或多个第二UE所在的小区。基站可以选择与第一UE同小区的第二UE作为中继UE。如此，将同小区的UE作为第一UE的中继，可以减小通信的复杂程度，提高通信效率。
如此，基站基于网络信息，基站可以基于网络信息，选择工作于第一工作状态的第二UE。保证选择的第二UE的网络状态可以满足第一工作状态的需求，进而提高通信质量。
在一个实施例中，信息传输方法可以包括：
向所述基站发送所述一个或多个第二UE的直连链路无线信号测量结果，
其中，所述网络信息和所述直连链路无线信号测量结果用于由所述基站在所述一个或多个第二UE中选择所述至少一个第二UE。
这里，第一UE和第二UE可以通过直连链路进行通信，第一UE在上报一个或多个第二UE，即备选的中继UE时，可以上报第一UE测量的与第二UE的直连链路的直连链路无线信号测量结果。其中，直连链路无线信号测量结果可以包括无线信号的参考信号接收功率(RSRP，Reference Signal Receiving Power)和/或参考信号接收质量(RSRQ，Reference Signal Receiving Quality)等。
基站接收到各第二UE，即各备选的中继UE的直连链路无线信号测量结果后，可以结合网络信息，基于预定的选择规则选择适合进行中继的UE。例如，可以选择RSRP和/或RSRQ大于或等于预设阈值，并且与第一UE同属一个移动通信网络的第二UE作为中继UE；也可以选择RSRP和/或RSRQ大于或等于预设阈值，并且与第一UE同属一个小区的UE作为中继UE。
如此，通过通信信号质量以及网络信息表征的网络符合性两个维度选 择适合工作于第一工作状态，如中继工作状态的第二UE，可以提高选择的第二UE可以符合第一工作状态的要求，进而提高通信质量，减少中继数据传输错误的情况。
在一个实施例中，步骤301可以包括：
接收所述一个或多个第二UE通过直连链路广播的所述网络信息；
接收所述一个或多个第二UE通过所述直连链路单播的所述网络信息。
这里，第二UE可以通过直连链路广播自身的网络信息，如驻留小区或PLMM标识等。第一UE可以不需要建立与第二UE的直连链接获取第二UE的网络信息。
第一UE也可以通过向第二UE发送指令等方式，在第一UE和第二UE建立的直连链路上，由第二UE单播将网络信息发送给第一UE。
如此，可以提高网络信息发送的灵活性。
在一个实施例中，信息传输方法可以包括：接收携带有标识信息的RRC重配信息，其中，所述标识信息用于标识所述一个或多个第二UE；
步骤302可以包括：向所述基站发送所述标识信息所标识的所述一个或多个第二UE的所述网络信息。
这里，一个或多个第二UE可以是基站通过RRC重配信息中携带的标识信息指示的。第一UE接收到标识信息后，可以将标识信息所指示的一个或多个第二UE的网络信息，发送给基站。
如果基站无法确定第一UE上报的备选中继UE的网络状态，基站可以通过RRC重配信息携带作为备选中继UE的第二UE的标识信息，用以指示第一UE上报备选中继UE的网络状态。第一UE接收标识信息所指示的第二UE在直连链路中广播的网络信息，并将接收的网络信息发送给基站。这里，标识信息可以是第二UE在网络中具有唯一性的标识，如第二UE在于第一UE直连链路中的身份标识等。
如此，基站可以通过下行RRC重配信息指示第一UE发送基站无法确定网络状态的第二UE的网络信息，基于网络信息选择第二UE在第一工作状态下进行工作。确保第二UE的网络状态可以符合第一工作状态的要求，减少由于第二UE不符合第一工作状态的要求产生的数据传输错误情况。利用RRC重配信息携带标识信息实现了RRC重配信息的复用。
在一个实施例中，所述标识信息包括：直连链路标识，其中，所述直连链路标识包括：直连链路层1标识、和/或直连链路层2标识。
在第一UE和第二UE的直连链路通信中，直连链路标识可以唯一表征一个第二UE。第一UE上包备选中继UE时，可以通过上报直连链路标识的形式进行上报。当基站无法确定任一第二UE的网络状态时，可以通过标识信息指示第一UE获取对应的第二UE的网络信息。如此，可以提高获取网络信息的针对性，提高获取网络信息的效率。
在一个实施例中，信息传输方法可以包括：向所述一个或多个第二UE发送携带有网络信息发送指示的所述RRC重配信息，其中，所述网络信息发送指示用于指示所述一个或多个第二UE发送所述网络信息；
步骤301可以包括：接收所述一个或多个第二UE响应于所述网络信息发送指示分别发送的所述网络信息。
这里，从基站接收的RRC重配信息还可以包括网络信息发送指示。第一UE接收到网络信息发送指示后，可以向第二UE转发RRC重配信息，用于指示第二UE通过直连链路发送自身的网络信息。第二UE接收到RRC重配信息后，可以通过直连链路单播向第一UE发送网络信息。第一UE在接收到单播的网络信息后，将该网络信息转发给基站。其中，RRC重配信息可以是sidelinkRRCReconfigure消息。
这里，第一UE接收到RRC重配信息后，可以结合标识信息和网络信息发送指示，向标识信息所指示的第二UE发送网络信息发送指示。如此， 针对仅针对没有获取到网络信息的第二UE发送网络信息发送指示，以获取网络信息。针对已经获取到网络信息的第二UE不发送网络信息发送指示，节省网络传输资源。
如此，针对仅针对没有获取到网络信息的第二UE发送网络信息发送指示，以获取网络信息；针对不同第二UE采用不同方式获取网络信息，提高获取网络信息的方式的多样性。
在一个实施例中，所述网络信息包括以下之一：
处于连接态的所述一个或多个第二UE的PLMN标识、和/或处于所述连接态的所述一个或多个第二UE所连接小区的小区标识、和/或所述处于连接态的所述一个或多个第二UE针对所连接小区的无线信号测量结果；
处于空闲态的所述一个或多个第二UE的PLMN标识、和/或处于所述空闲态的所述一个或多个第二UE所驻留小区的小区标识、和/或所述处于空闲态的所述一个或多个第二UE针对所驻留小区的无线信号测量结果；
处于非激活态的所述一个或多个第二UE的PLMN标识、和/或处于所述非激活态的所述一个或多个第二UE所驻留小区的小区标识、和/或所述处于非激活态的所述一个或多个第二UE针对所驻留小区的无线信号测量结果。

针对连接态的一个或多个第二UE，网络信息可以是第二UE所连接小区标识，基站可以根据第二UE所连接小区标识确定第二UE是否处于基站覆盖范围，当第二UE处于基站覆盖范围时，可以选择该第二UE工作于第一工作状态。
