具体实施方式
为了能够更加详尽地了解本申请实施例的特点和技术内容,下面结合附图对本申请实施例的实现进行详细阐述,所附附图仅供参考说明之用,并非用来限定本申请实施例。
在对本申请实施例进行说明之前,对相关内容进行简要说明。
设备到设备(Device to Device,D2D)通信是基于侧行链路(Sidelink,SL)的传输技术,与传统的蜂窝系统中通信数据通过网络设备接收或者发送的方式不同,因此具有更高的频谱效率以及更低的传输时延,车联网系统采用D2D通信的方式(即设备到设备直接通信的方式)。在新无线(New Radio,NR)系统中,对于D2D通信,第三代合作伙伴计划(Third Generation Partnership Project,3GPP)定义了两种传输模式:第一模式(也称为模式A)和第二模式(也称为模式B)。第一模式是网络设备为终端设备分配传输资源,第二模式是终端设备自主选择传输资源。
针对第一模式:如图1所示,终端设备的传输资源是由网络设备分配的,终端设备根据网络设备分配的资源在侧行链路上进行数据的发送;网络设备可以为终端设备分配单次传输的资源,也可以为终端设备分配半静态传输的资源。
针对第二模式:如图2所示,终端设备在资源池中选择一个传输资源进行数据的发送。
终端设备既可以使用第一模式获取传输资源,也可以使用第二模式获取传输资源,还可以同时使用第一模式和第二模式获取传输资源。其中,传输资源的获取可通过侧行链路授权的方式指示,作为示例,侧行链路授权指示相应的侧行链路控制信道(Pysical Sidelink Control Channel,PSCCH)资源和侧行链路共享信道(Physical Sidelink Shared CHannel,PSSCH)资源的时频位置。
在NR V2X中,终端设备可以自主发起混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)重传;作为示例,在NR V2X的单播通信和组播通信中均可以引入基于反馈的HARQ重传。
在3GPP版本(Rel)12/13中,针对近场通信服务(Proximity based Service,ProSe),可通过配置资源池在时域上的位置,例如资源池在时域上非连续,达到终端设备在侧行链路上非连续发送和/或接收数据,从而达到省电的效果。
在R14/15中,车联网系统针对车-车通信的场景进行了要求,其主要面向相对高速移动的车-车、车-人通信的业务。
在V2X系统中,由于车载系统具有持续的供电,因此数据传输的时延是主要解决的问题,因此,在系统设计上要求终端设备进行连续的发送和接收。
在R14中,对于可穿戴设备(FeD2D)通过手机接入网络的场景进行了研究,尤其是针对低移动速度以及低功率接入的场景。针对FeD2D,网络设备可以通过一个中继(relay)终端配置远端(remote)终端的DRX参数。
下面对终端设备的连接建立过程进行简要说明。
终端设备在发起呼叫之前,首先要进行接入控制。接入控制从执行者的角度来区分可以两种,第一种是由终端设备自己执行的,在NR系统中统称为统一接入控制(Unified Access Control,UAC),第二种是由网络设备根据无线资源控制(Radio Resource Control,RRC)建立请求(SetupRequest)消息中的“RRC建立原因”(RRC Establishment cause)来执行。第二种接入控制的关键在于终端设备的非接入层(Non Access Stratum,NAS)层在发起呼叫时,会根据接入标识和接入类别映射得到一个“RRC建立原因”。该“RRC建立原因”由RRC层编码在RRCSetupRequest消息中发送给网络设备。而网络设备如 何根据“RRC建立原因”来进行接入控制则是属于网络设备的内部算法,由网络设备实现。如果网络设备接纳终端设备发起的RRCSetupRequest消息,则网络设备会发送RRCSetup消息进行响应,否则会发送RRCReject(RRC拒绝)消息进行拒绝。
在R13中引入了基于层3中继的终端设备到网络设备(UE-to-network)中继功能,即远端终端设备通过中继终端设备接入网络。中继终端设备承担网络协议(Internet Protocol,IP)层中继的功能,在远端终端设备和网络设备之间传递数据,远端终端设备和中继终端设备通过侧行链路相连。中继网络的连接建立流程,可以如图3所示:在步骤5中,中继终端设备向网络设备上报远端终端设备的标识(ID)以及IP信息,网络设备根据此上报消息,获知中继终端设备和远端终端设备的关联关系,从而进行相应的承载/会话管理以及配置,从而使得远端终端设备通过中继终端设备连接到网络。
对于基于层2中继的UE-to-network中继功能,即远端终端设备通过中继终端设备接入网络。中继终端设备承担适应层中继的功能,在远端终端设备和网络设备之间传递数据,远端终端设备和中继终端设备通过侧行链路相连。其中,适应层位于无线连接控制(Radio Link Control,RLC)层之上,分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层之下。但是,相关技术中尚未明确基于层2中继的UE-to-network的连接建立过程。
