首先,对本申请实施例涉及的相关技术背景进行介绍:
LTE D2D/V2X:设备到设备通信是基于D2D的一种侧行链路(Sidelink,SL)传输技术,也称侧行通信技术,与传统的蜂窝系统中通信数据通过基站接收或者发送的方式不同,侧行通信系统采用终端到终端直接通信的方式,因此具有更高的频谱效率以及更低的传输时延。在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)中,为侧行通信定义了两种传输模式:模式A和模式B。
模式A:终端的传输资源是由基站分配的,终端根据基站分配的资源在侧行链路上进行数据的发送;基站可以为终端分配单次传输的资源,也可以为终端分配半静态传输的资源。
模式B:终端在资源池中自主选取资源进行数据的传输。
在侧行通信系统中,以上述终端用户设备(User Equipment,UE)为例,工作场景主要有以下几种情况。
如图1所示,两个UE均在网络覆盖范围内且位于相同的小区,基站分配侧行传输资源给两个UE,两个UE根据基站分配的侧性传输资源在SL上进行数据传输。
图2中,两个UE均在网络覆盖范围内且位于相同的小区,UE在资源池中自主选取资源在SL进行数据传输。
图3中,UE1位于网络覆盖范围内,UE2位于网络覆盖范围外。UE1是接收终端,UE2是发送终端;或者,UE1是发送终端,UE2是接收终端。UE1可以接收基站分配的传输资源与UE2进行侧行通信,或者,UE1基于UE2发送的配置要求,在基站分配的传输资源中选择资源与UE2进行侧行通信。UE1也可以在资源池中自主选取资源与UE2进行侧行通信,或者,UE1基于UE2发送的配置要求,在资源池中自主选择资源与UE2进行侧行通信。
在3GPP中,D2D分成了不同的阶段进行研究。
基于邻近的服务(Proximity based Service,ProSe):在3GPP第12版和第13版(Rel-12/13)中设备到设备通信,是针对ProSe的场景进行了研究,其主要针对公共安全类的业务。在ProSe中,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UE在SL上非连续发送/接收数据,从而达到省电的效果。
车联网(Vehicle to Everything,V2X):在Rel-14/15中,V2X系统针对车车通信的场景进行了研究,其主要面向相对高速移动的车车、车人通信的业务;在V2X中,由于车载系统具有持续的供电,因此功率效率不是主要问题,而数据传输的时延是主要问题,因此在系统设计上要求终端设备进行连续的发送和接收。
进一步增强的D2D(Further Enhanced Device to Device,FeD2D):在Rel-14中,这个场景对于可穿戴设备通过手机接入网络的场景进行了研究,其主要面向是低移动速度以及低功率接入的场景。在FeD2D中,在预研阶段3GPP结论为基站可以通过一个中继(relay)终端去配置远程(remote)终端的不连续接收(Discontinuous Reception,DRX)参数,但是由于该课题没有进一步进入标准化阶段,如何进行DRX配置的具体细节没有结论。
NR V2X:NR V2X在LTE V2X的基础上,不局限于广播场景,而是进一步拓展到了单播和组播的场景,在这些场景下研究V2X的应用。
类似于LTE V2X,NR V2X也会定义上述模式A(在NR V2X中命名为模式一,Mode-1)和模式B(在NR V2X中命名为模式二,Mode-2)两种资源授权模式;更进一步,用户可能处在一个混合的模式下,即既可以使用Mode-1进行资源的获取,又同时可以使用Mode-2进行资源的获取。该资源获取通过侧行链路授权的方式指示,即侧行链路授权指示相应的物理侧行链路控制信道(Physical Sidelink Control CHannel,PSCCH)与物理侧行链路共享信道(Physical Sidelink Shared CHannel,PSSCH)资源的时频位置。
不同于LTE V2X,除了无反馈的、UE自主发起的混合自动重传请求(HybridAutomaticRepeatreQuest,HARQ)重传,NR V2X引入了基于反馈的HARQ重传,不限于单播通信,也包括组播通信。
NR Uu CA:CA是从长期演进技术升级版(LTE-Advanced)标准就开始支持的一种带宽扩展技术,可以将多个成员载波(Component Carrier,CC)聚合在一起,由一个UE同时接收或发送。按照聚合的载波的范围分,CA又可以分为频带内CA(intra-band CA)和跨频带CA(inter-band CA)。Intra-band CA的一个主要用途是用于小区载波带宽大于UE的单个载波带宽能力的场景,这种情况下,UE可以用CA方式来实现在“宽载波”(wide carrier)中的操作。例如基站支持300MHz一个载波,而UE只支持最大100MHz的载波,此时UE可以用CA方式实现大于100MHz的宽带操作,聚合的载波可以是相邻的载波,也可以是不相邻的载波。
当终端和网络通过CA进行通信时,可能会同时配置主小区(Primary Cell,PCell)和辅小区(Secondary Cell,SCell)。在NR R15版本中,针对PCell和辅主小区(SecondaryPrimaryCell,PSCell)设计了波束失败恢复机制,其主要功能模块(或称为主要步骤)分为4个:
·波束失败检测(Beam Failure Detection,BFD)。
·新波束选择(New Beam Identification,NBI)。
·波束失败恢复请求(Beam Failure Recovery ReQest,BFRQ)。
·网络侧响应。
终端对物理下行控制信道(Physical Downlink Control CHannel,PDCCH)进行测量,判断下行发送波束对应的链路质量。如果对应的链路质量很差,则认为下行波束发生波束失败。终端还会对一组备选波束进行测量,从中选择满足一定门限的波束作为新波束。然后终端通过波束失败恢复请求(Beam Failure Recovery reQuest,BFRQ)流程,通知网络发生了波束失败,并且上报新波束。网络收到一个终端发送的BFRQ信息后,知道所述终端发生了波束失败,选择从新波束上发送PDCCH,终端在新波束上收到网络发送的PDCCH则认为正确接收了网络侧的响应信息。至此,波束失败恢复流程成功完成。
应理解,在本申请的一些实施例中,小区和载波可以等同。例如,“第一载波”可以替换为“第一小区”,“第二载波”可以替换为“第二小区”,等等。
应理解,在本申请的一些实施例中,“5G NR系统”也可以称为5G系统或者新空口(NewRadio,NR)系统。本申请的一些实施例中描述的技术方案可以适用于5G NR系统,也可以适用于5G NR系统后续的演进系统,还可以适用于6G以及后续的演进系统。
应理解,在本申请的一些实施例中,“确定载波”可以理解为“选择载波”或“决定载波”。
在目前的NR技术中,仅支持终端和基站之间的CA技术。而本申请提供了一种载波确定方法,能够应用于基于CA的侧行链路通信中,也即使得两个终端之间的侧行链路也能使用CA技术。在基于CA的侧行链路通信中,当侧行链路工作在多个载波上时,通过定义映射关系,和/或,通过网络设备控制,和/ 或,基于两个终端之间的协商,来进行载波或主载波的确定配置,使得第一终端使用确定后的第一载波或第一主载波与第二终端进行侧行链路通信,以达到在NR SL中确定所要使用的载波或主载波来进行侧行链路数据传输的目的。
示例性的如图4所示,终端1和终端2的侧行链路上共有5个可用载波或候选载波可供侧行数据传输。终端1确定载波2和载波4进行载波聚合,终端1使用该载波2和载波4实现与终端2进行基于载波聚合的通信。

在一些实施例中,第一终端基于映射关系确定第一载波。该映射关系包括侧行链路的属性与载波之间的映射关系。该侧行链路的属性包括:服务类型(Service Type)、应用类型、层二标识(IDentity,ID)、发送属性(Txprofile)、数据传输类型、服务质量(Quality of Service,QoS)、逻辑信道、资源池、无线承载、数据优先级、资源池拥塞程度中的至少一种。其中资源池拥塞程度可以基于CBR来衡量。该映射关系是预定义的,或网络设备向第一终端配置的,或第二终端向第一终端配置的,或第一终端自主决定的。

在一些实施例中,第一终端与第二终端协商确定第一载波。第一终端与第二终端基于直连通信接口PC5接口协商确定第一载波。可选地,由第一终端作为载波确定方,第一终端先确定第一载波后,向第二终端通知第一载波,或第一终端与第二终端确认第一载波是否可用。可选地,由第二终端作为载波确定方,第二终端先确定第一载波后,向第一终端通知第一载波,或第二终端与第一终端确认第一载波是否可用。
步骤540:第一终端使用第一载波与第二终端进行侧行链路通信。

在一些实施例中,终端具有CA或双连接(Dual Connectivity,DC)的能力。
在一些实施例中,终端不具有CA或DC的能力,或终端具有CA或DC的能力但未启用CA或DC。
在一些实施例中,第一终端和第二终端均处于网络覆盖范围内且位于相同的小区。
在一些实施例中,第一终端和第二终端均处于网络覆盖范围内但位于不同的小区。
在一些实施例中,第一终端处于网络覆盖范围内,第二终端处于网络覆盖范围外。
在一些实施例中,第一终端处于网络覆盖范围外,第二终端处于网络覆盖范围内。
在一些实施例中,第一终端和第二终端均处于网络覆盖范围外。
在一些实施例中,第一终端是发送终端,第二终端是接收终端;和/或,第一终端是接收终端,第二终端是发送终端。
上述方法适用于基于模式一的侧行通信场景,和/或,基于模式二的侧行通信场景。
综上所述,本实施例提供的方法,通过使用更灵活的载波确定配置机制,在引入CA技术的情况下,能够确定某个合适的载波或者使用至少两个载波进行CA,从而提高侧行链路上的数据传输性能,达到提升侧行通信系统的传输性能的目的。
