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、完整地描述,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在没有作出创 造性劳动前提下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,且“第一”、“第二”等所区分的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。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。
在进行本发明实施例的说明时,首先对下面描述中所用到的一些概念进行解释说明。
旁链路(Sidelink,也称直通链路)简介:
Sidelink是指新空口(New Radio,NR)/长期演进(Long Term Evolution,LTE)中UE跟UE之间的无线链路,两个UE可以通过旁链路实现两者之间的直接数据传输。旁链路之间的无线链路又称为PC5链路,运行的是PC5协议。在第三代合作伙伴计划(3 rd Generation Partnership Project,3GPP)Rel-17,将研究使用UE提供UE到网络之间的中继服务,如图1所示,其中,提供中继服务的UE称为中继UE(即relay UE),而被提供中继服务的UE被称为远端UE(即remote UE),中继UE和远端UE之间的链路是PC5链路,运行旁链路接口协议,中继UE跟基站之间的链路是Uu链路,运行Uu link协议。
旁链路的无线接口控制面有PC5无线资源控制(Radio Resource Control,RRC)协议,运行在分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层和无线链路控制(Radio Link Control,RLC)层之上,最下面是媒体接入控制(Medium Access Control,MAC)层和物理(Physical,PHY)层。旁链路的无线接口用户面自上到下包括服务数据适配协议(Service Data Adaptation Protocol,SDAP),PDCP,RLC、MAC和物理层。
层2旁链路中继和层3旁链路中继简介:
目前在3GPP讨论的中继结构有层二(Layer 2,也可称为层2)和层三(Layer3,也可称为层3)两种类型。图2和图3分别展示了基于层2中继的 回传链路控制面协议栈和基于层3旁链路中继的回传链路控制面协议栈。对于基于层2旁链路中继的回传链路,远端UE有一个PC5的RRC连接(图中仅给出了Uu RRC协议栈),用于控制旁链路连接,同时有一个于基站的RRC连接,用于控制与基站间的连接和业务提供。对于基于层3旁链路中继的回传链路,远端UE有一个与中继UE的PC5RRC连接,没有与基站的Uu RRC连接。层3中继的协议栈省略。其中,流控制传输协议(SCTP,Stream Control Transmission Protocol),非接入层(Non-Access Stratum,NAS),下一代应用协议(Next Generation Application Protocol,NG-AP)为NG应用协议。
Uu口无线链路建立流程:
现有无线链路建立的RRC信令流程如图4所示。一个UE先通过发送物理随机接入信道(Physical Random Access Channel,PRACH)信号给基站,基站收到PRACH信号后会发送一个用于发送消息三(Msg3)的上行传输许可给UE,UE收到上行传输许可后,在Msg3中发送无线资源控制建立请求(RRCSetupRequest)。然后基站会根据收到的RRCSetupRequest,给UE发送无线资源控制建立(RRCSetup)消息,RRCSetup消息中携带的配置信息用于配置UE跟基站之间的无线连接配置参数,包括无线承载和主小区组的配置等。UE在收到RRCSetup消息后,依据其中的配置参数,完成无线链路配置,然后向基站发送无线链路控制建立完成(RRCSetupComplete)消息。
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信息传输方法、终端及网络设备进行详细地说明。
如图5所示,本申请实施例提供一种信息传输方法,包括:
步骤501,第一终端发送第一信息给网络设备;
其中,所述第一信息用于请求所述网络设备为第一终端进行中继回路配置;所述第一信息为旁链路中继回路建立请求指示信息或第一终端的类型指示信息。
需要说明的是,该第一终端为能够提供中继服务的中继终端。
需要说明的是,该第一终端的类型指示信息具体用于指示以下至少一项:
A11、第一终端为具有层二旁链路中继功能的终端;
A12、第一终端为具有层三旁链路中继功能的终端。
也就是说,当第一终端发送第一终端的类型指示信息给网络设备时,当第一终端只具备基于层二旁链路中继结构的模式时,该类型指示信息指示第一终端为具有层二旁链路中继功能的终端;当第一终端只具备基于层三旁链路中继结构的模式时,该类型指示信息指示第一终端为具有层三旁链路中继功能的终端;当第一终端既具备基于层二旁链路中继结构的模式也具备基于层三旁链路中继结构的模式时,该类型指示信息指示第一终端为既具有层二旁链路中继功能也具有层三旁链路中继功能的终端。
进一步需要说明的是,所述旁链路中继回路建立请求指示信息,包括以下至少一项:
A21、请求建立旁链路中继回路的第一指示;
A22、旁链路中继的工作模式的第二指示;
需要说明的是,该工作模式指的是为基于层二旁链路中继结构的模式和/或基于层三旁链路中继结构的模式。
A23、旁链路中继回路的回传业务信息的第三指示;
需要说明的是,该回传业务信息通常指的是业务的类型,例如,视频业务,语音业务等。
A24、第一终端的类型指示信息。
进一步地,还需要说明的是,步骤501的具体实现方式为:
第一终端发送第一信令给网络设备,所述第一信令中携带所述第一信息;
其中,所述第一信令包括:无线资源控制建立请求消息(RRCSetupRequest消息)、无线资源控制建立完成消息(RRCSetupComplete消息)、无线连接恢复请求消息(RRCResumeRequest消息)、无线连接恢复请求消息一(RRCResumeRequest1消息)、无线连接恢复完成消息(RRCResumeComplete消息)、终端辅助消息(UEAssistanceInformation)和第一无线资源控制(RRC)消息中的至少一项,需要说明的是,该第一RRC消息为本申请中新引入的用于承载第一信息的RRC消息,即新的RRC消息,例如,该新的RRC消息可以命名为旁链路中继建立请求消息(SidelinkRelaySetupRequest消息)。
需要说明的是,当第一终端与网络设备之间未建立Uu链路时,第一终端可以在Uu无线链路建立过程请求网络设备为其进行中继回路配置,此时, 第一终端可以在RRCSetupRequest消息、RRCSetupComplete消息、RRCResumeRequest消息、RRCResumeRequest1消息或RRCResumeComplete消息中将第一信息发送给网络设备;当第一终端与网络设备之间已建立Uu链路时,第一终端可以在UEAssistanceInformation或新的RRC消息中将第一信息发送给网络设备。
例如,当第一终端在RRCSetupRequest消息、RRCResumeRequest消息或RRCResumeRequest1消息中携带旁链路中继回路建立请求指示信息时,其中一种方法是重定义RRCSetupRequest消息的建立原因(establishmentCause)的空闲值域(即spare‘x’),或RRCResumeRequest消息/RRCResumeRequest1消息中的恢复原因(resumeCause)字段的空闲值域(即spare‘x’)承载旁链路中继回路建立请求指示信息。例如用一个空闲值指示第一终端基于层三旁链路中继结构的模式和/或一个空闲值域指示第一终端基于层二旁链路中继结构的模式,另,例如用一个空闲值域第一终端基于层二旁链路中继结构的模式并指示回传业务信息为具体业务类型(例如,语音、视频和背景数据传输业务等);另一种方法是使用其中的一个空闲比特作为旁链路中继回路建立请求指示信息,用于指示第一终端基于层三(或层二)旁链路中继结构的模式。
例如,若第一终端在RRCSetupComplete消息或RRCResumeComplete消息携带旁链路中继回路建立请求指示信息时,即在这两个已有的RRC消息中引入新的指示参数用于指示第一终端为基于层二旁链路中继结构的模式或基于层三旁链路中继结构的模式,可选地,还可以在这两个已有的RRC消息中引入新的指示参数用于指示回传业务信息为具体业务类型(例如,语音、视频和背景数据传输业务等)。
进一步需要说明的是,当网络设备接收到第一终端发送的第一信息时,可以选择发送拒绝消息给第一终端、以拒绝中继回路建立请求。收到中继回路拒绝请求后,第一终端拒绝远端终端通过该第一终端接入网络;网络设备还可以响应该第一信息,发送中继回路通道建立的配置信息给第一终端,进而第一终端在接收网络设备发送的中继回路通道建立的配置信息后,根据所述配置信息,配置回传通道。
具体地,该配置信息,包括以下至少一项:
A31、上行和下行回传逻辑信道的配置参数;
例如,该配置参数可以为用于传输远端终端的SRB0的回传逻辑信道配置,可理解为默认回传逻辑信道配置。
A32、第二终端的接入许可参数;
需要说明的是,该第二终端指的是远端终端。
例如,该接入许可参数可以为是否允许远端终端接入、允许远端终端接入的业务类型等。
A33、PC5逻辑信道和Uu回传逻辑信道的配置映射关系;
A34、回传通道流量控制配置参数。
还需要说明的是,若第一终端通过RRCSetupRequest消息发送第一信息给网络设备,则网络设备可以通过无线资源控制建立消息(RRCSetup消息)和/或无线资源控制重配置消息(RRCReconfiguration消息)将中继回路通道建立的配置信息发送给第一终端;若第一终端通过RRCResumeRequest消息或RRCResumeRequest1消息发送第一信息给网络设备,则网络设备可以通过无线连接恢复消息(RRCResume消息)和/或RRCReconfiguration消息将中继回路通道建立的配置信息发送给第一终端;若第一终端通过RRCSetupComplete消息、RRCResumeComplete消息、UEAssistanceInformation消息或新的RRC消息发送第一信息给网络设备,则网络设备可以通过RRCReconfiguration消息将中继回路通道建立的配置信息发送给第一终端。
可选地,在所述步骤501之后,本申请实施例的所述方法还包括:
第一终端发送旁链路中继配置请求给网络设备。
具体地,所述旁链路中继配置请求包括:与旁链路中继相关的系统消息的配置请求或与第一终端的中继功能相关的配置请求。
需要说明的是,此种情况的一种应用场景为:中继回路已经建立,但是回路中又有新的业务传输,此时需要更新旁链路中继配置,这时就需要发送旁链路中继配置请求给网络设备以实现配置的更新。
进一步地,该旁链路中继配置请求还可以用于隐示指示以下至少一项:
A41、第一终端具备旁链路中继的功能;
A42、第一终端愿意作为旁链路中继使用;
A43、第一终端请求网络设备配置为中继终端使用或者向网络设备表明有中继业务需求。
进一步地,网络设备在接收到旁链路中继配置请求后,可以发送中继回路配置信息给第一终端,第一终端接收到该中继回路配置信息后可以进行中继回路的配置。
这里需要说明的是,该中继回路配置信息包括以下至少一项:旁链路时频资源配置和与中继业务相关的无线承载配置。
综上可知,本申请实施例通过由第一终端向网络设备发送第一信息,以请求网络设备为第一终端进行中继回路配置,以此完善了网络通信流程,保证了中继通信的可靠性,且本申请实施例的此种旁链路中继的回传通道建立方式,能够降低回传通道建立时延。
