本申请实施例中的网络设备可以是用于与终端设备通信的设备,该网络设备也可以称为接入网设备或无线接入网设备,如网络设备可以是基站。本申请实施例中的网络设备可以是指将终端设备接入到无线网络的无线接入网(radio access network,RAN)节点(或设备)。基站可以广义的覆盖如下中的各种名称,或与如下名称进行替换,比如:节点B(NodeB)、演进型基站(evolved NodeB,eNB)、下一代基站(next generation NodeB,gNB)、中继站、接入点、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、主站MeNB、辅站SeNB、多制式无线(MSR)节点、家庭基站、网络控制器、接入节点、无线节点、接入点(access piont,AP)、传输节点、收发节点、基带单元(base band unit,BBU)、射频拉远单元(Remote Radio Unit,RRU)、有源天线单元(active antenna unit,AAU)、射频头(remote radio head,RRH)、中心单元(central unit,CU)、分布式单元(distributed unit,DU)、定位节点等。基站可以是宏基站、微基站、中继节点、施主节点或类似物,或其组合。基站还可以指用于设置于前述设备或装置内的通信模块、调制解调器或芯片。基站还可以是移动交换中心以及设备到设备D2D、V2X、机器到机器(machine-to-machine,M2M)通信中承担基站功能的设备、6G网络中的网络侧设备、未来的通信系统中承担基站功能的设备等。基站可以支持相同或不同接入技术的网络。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。

网络设备和终端设备可以部署在陆地上,包括室内或室外、手持或车载;也可以部署在水面上;还可以部署在空中的飞机、气球和卫星上。本申请实施例中对网络设备和终端设备所处的场景不做限定。
不同网络覆盖情况下的侧行通信
侧行通信指的是基于侧行链路的通信技术。侧行通信例如可以是设备到设备(device to device,D2D)或车联网(vehicle to everything,V2X)通信。传统的蜂窝系统中的通信数据在终端设备和网络设备之间进行接收或者发送,而侧行通信支持在终端设备与终端设备之间直接进行通信数据传输。相比于传统的蜂窝通信,终端设备与终端设备直接进行通信数据的传输可以具有更高的频谱效率以及更低的传输时延。例如,车联网系统采用侧行通信技术。
在侧行通信中,根据终端设备所处的网络覆盖的情况,可以将侧行通信分为网络覆盖内的侧行通信,部分网络覆盖的侧行通信,及网络覆盖外的侧行通信。
图2为网络覆盖内的侧行通信的场景示例图。在图2所示的场景中,两个终端设备120a均处于网络设备110的覆盖范围内。因此,两个终端设备120a均可以接收网络设备110的配置信令(本申请中的配置信令也可替换为配置信息),并根据网络设备110的配置信令确定侧行配置。在两个终端设备120a均进行侧行配置之后,即可在侧行链路上进行侧行通信。
图3为部分网络覆盖的侧行通信的场景示例图。在图3所示的场景中,终端设备120a与终端设备120b进行侧行通信。终端设备120a位于网络设备110的覆盖范围内,因此终端设备120a能够接收到网络设备110的配置信令,并根据网络设备110的配置信令确定侧行配置。终端设备120b位于网络覆盖范围外,无法接收网络设备110的配置信令。在这种情况下,终端设备120b可以根据预配置(pre-configuration)信息和/或位于网络覆盖范围内的终端设备120a发送的物理侧行广播信道(physical sidelink broadcast channel,PSBCH)中携带的信息确定侧行配置。在终端设备120a和终端设备120b均进行侧行配置之后,即可在侧行链路上进行侧行通信。
图4为网络覆盖外的侧行通信的场景示例图。在图4所示的场景中,两个终端设备120b均位于网络覆盖范围外。在这种情况下,两个终端设备120b均可以根据预配置信息确定侧行配置。在两个终端设备120b均进行侧行配置之后,即可在侧行链路上进行侧行通信。
基于中央控制节点的侧行通信
图5为基于中央控制节点的侧行通信的场景示例图。在该侧行通信场景中,多个终端设备可以构成一个通信组,且该通信组内具有中央控制节点。该中央控制节点可以为通信组内的一个终端设备(如图5中的终端设备1),该终端设备又可以称为簇头(cluster header,CH)终端设备。该中央控制节点可以负责完成以下功能中的一项或多项:通信组的建立,通信组的组成员的加入和离开,在通信组内进行资源协调,为其他终端设备分配侧行传输资源,接收其他终端设备的侧行反馈信息,以及与其他通信组进行资源协调。
侧行通信的模式
某些标准或协议(如第三代合作伙伴计划(3rd Generation Partnership Project,3GPP))定义了两种侧行通信的模式:第一模式和第二模式。
在第一模式下,终端设备的资源(本申请提及的资源也可称为传输资源,如时频资源)是由网络设备分配的。终端设备可以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。该第一模式可以应用于有网络设备覆盖的场景,如前文图2所示的场景。在图2所示的场景中,终端设备120a位于网络设备110的网络覆盖范围内,因此网络设备110可以为终端设备120a分配侧行传输过程中使用的资源。
在第二模式下,终端设备可以自主在资源池(resource pool,RP)中选取一个或多个资源。然后, 终端设备可以根据选择出的资源进行侧行传输。例如,在图4所示的场景中,终端设备120b位于小区覆盖范围外。因此,终端设备120b可以在预配置的资源池中自主选取资源进行侧行传输。或者,在图2所示的场景中,终端设备120a也可以在网络设备110配置的资源池中自主选取一个或多个资源进行侧行传输。
侧行通信的数据传输方式
某些侧行通信系统(如长期演进-车联网(long term evolution vehicle to everything,LTE-V2X))支持基于广播的数据传输方式(下文简称广播传输)。对于广播传输,接收端终端可以为发送端终端周围的任意一个终端设备。以图6为例,终端设备1是发送端终端,该发送端终端对应的接收端终端是终端设备1周围的任意一个终端设备,例如可以是图6中的终端设备2-终端设备6。
除了广播传输之外,某些通信系统还支持基于单播的数据传输方式(下文简称单播传输)和/或基于组播的数据传输方式(下文简称组播传输)。例如,新无线-车联网(new radio vehicle to everything,NR-V2X)希望支持自动驾驶。自动驾驶对车辆之间的数据交互提出了更高的要求。例如,车辆之间的数据交互需要更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配模式等。因此,为了提升车辆之间的数据交互性能,NR-V2X引入了单播传输和组播传输。
对于单播传输,接收端终端一般只有一个终端设备。以图7为例,终端设备1和终端设备2之间进行的是单播传输。终端设备1可以为发送端终端,终端设备2可以为接收端终端,或者终端设备1可以为接收端终端,终端设备2可以为发送端终端。
对于组播传输,接收端终端可以是一个通信组内的终端设备,或者,接收端终端可以是在一定传输距离内的终端设备。以图8为例,终端设备1、终端设备2、终端设备3和终端设备4构成一个通信组。如果终端设备1发送数据,则该组内的其他终端设备(终端设备2至终端设备4)均可以是接收端终端。
载波聚合技术
为了满足单用户峰值速率和系统容量提升的要求,一种最直接的办法就是增加系统传输带宽。因此,通信系统中引入一项增加传输带宽的技术,也就是,载波聚合(carrier aggregation,CA)技术。利用CA技术,可以将多个(例如,2~5个)成员载波(component carrier,CC)聚合在一起,以提升传输带宽,有效提高了上下行传输速率。
在一些实现方式中,上述参与聚合的CC可以是在频段上相邻的载波,也可以是在频段上不相邻的载波。
在另一些实现方式中,可以按照聚合的载波的范围对CA技术进行分类,CA的类型可以分为频带内CA(intra-band CA)和跨频带CA(inter-band CA,或者说,频带间CA)。顾名思义,对于频带内CA而言,参与载波聚合的CC属于同一个频带。对于跨频带CA而言,参与载波聚合的CC属于多个不同的频带。
为了便于理解,下文以网络设备与终端设备通信的场景,以及终端设备与终端设备通信的侧行通信场景为例,介绍CA技术。
在网络设备与终端设备的通信场景中,CA是从LTE-Advanced标准就开始支持的一种带宽扩展技术,可以将多个CC聚合在一起,由一个终端设备同时接收或发送。在此场景中,频带内CA可以用于小区载波带宽大于终端设备的单个载波带宽能力的情况,这种情况下,终端设备可以用CA方式来实现在“宽载波”(wide carrier)中的操作。
例如,网络设备支持300MHz的载波,而终端设备只支持最大100MHz的载波,此时,为了提高终端设备与网络设备之间的传输速率,终端设备可以用CA方式,利用大于100MHz的宽带与网络设备通信。
在一些场景中,当终端设备和网络设备之间基于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),其中,辅小区中又可以包括辅主小区(primary secondry cell,PSCell)。目前,在已知的通信协议(例如,NR R15版本)中,针对PCell和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)可以分为以下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)以及网络侧响应。
也就是说,在波束失败检测步骤中,终端设备可以对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。而后进入新波束选择步骤,终端设备可以对一组备选波束进行测量,从备选波束中选择满足一定门限的波束作为新波束。然后终端设备通过BFRQ流程,通知网络设备发生了波束失败,并且上报选择的新波束。相应地,在网络侧响应步骤中,网络设备在收到终端设备发送的BFRQ信息后,可以知道终端设备发生了波束失败,并选择从新波束上发送PDCCH,然后,网络设备在新波束上向终端设备发送PDCCH,相应地,终端设备在新波束上 收到PDCCH之后,则可以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。
在侧行通信场景中,当终端设备以广播或组播的方式与其他终端设备进行通信时,该终端设备可以基于预存的业务类型(service type)与载波集合的映射关系,选择待传输数据所属的业务对应的载波集合,并基于选择的载波集合进行载波聚合,以与其他终端设备通信。
在一些实现方式中,终端设备可以基于CRB从上述选择载波集合中,确定进行载波聚合的CC。例如,终端设备可以测量资源池中的CBR值,并与待传输数据的优先级所对应的CBR门限值相比较,若测量的CBR值低于CBR门限,则终端设备可以认为此载波可用于载波聚合。相反地,若测量的CBR值高于或等于CBR门限,则终端设备可以认为此载波不可用于载波聚合。
基于上文的介绍可知,侧行链路通信时使用的多个载波(或者说至少两个载波),需要基于载波与业务类型的映射关系确定,然而,这种映射关系是固定的,不容易改变的。这种,基于固定映射关系确定载波的方式并不灵活。
因此,为了避免上述问题,本申请实施例提供了一种无线通信方法,第一终端设备可以为第二终端设备配置侧行链路上使用的多个载波,使得侧行链路上使用的多个载波可以基于配置变化,有助于提高侧行链路中配置多个载波的灵活性。
为了便于理解,下文以第一终端设备和第二终端设备为例,结合图9介绍本申请实施例的无线通信的方法。其中,第一终端设备和第二终端设备之间可以通过第一侧行链路进行单播通信。图9是本申请实施例的无线通信方法的示意性流程图。图9所示的方法包括步骤S910。
在步骤S910中,第一终端设备向第二终端设备发送针对第一侧行链路的载波配置信息。
上述载波配置信息用于配置第一侧行链路上的至少两个载波。其中,至少两个载波可以包括参与载波聚合的载波,或者说,至少两个载波可以包括参与载波聚合的载波成员。因此,可替换地,上述载波配置信息可以用于在第一侧行链路上进行载波聚合的相关配置。
另外,在本申请实施例中,上述载波配置信息可以以载波集合的方式配置第一侧行链路上的载波,其中,载波集合中可以包括上述至少两个载波。
在一些场景中,上述第一终端设备向第二终端设备发送载波配置信息,可以理解为,第一终端设备为第二终端设备配置第一侧行链路上的至少两个载波,也就是说,第一终端设备可以控制第二终端设备使用的载波,因此,第一终端设备又可以称为“控制方终端设备”,第二终端设备又可以称为“被控制方终端设备”。
通常,不同的终端设备支持的载波不同,第一终端设备可能无法确定第二终端设备支持的载波,此时,第一终端设备可能为第二终端设备配置了第二终端设备并不支持的载波,导致载波配置失败。
因此,为了提高载波配置的成功率,第二终端设备可以向第一终端设备发送配置辅助信息(例如,“第一配置辅助信息”),以辅助第一终端设备为第二终端设备配置第一侧行链路上的至少两个载波,或者说,第一配置辅助信息用于确定载波配置信息。因此,上述配置辅助信息又可以称为“载波配置辅助信息”。
在一些实现方式中,上述第一配置辅助信息可以包括第二终端设备期望配置的载波。一方面,第二终端设备期望配置的载波的确定可以考虑第二终端设备的载波情况。通常,在某一通信链路上使用了一个载波后,该载波可能无法同时在其他链路上使用。因此,上述第二终端设备期望的载波可以是基于第二终端设备的其他通信链路上使用的载波确定的。其中,其他通信链路可以是第二终端设备中除第一侧行链路之外的通信链路,并且,其他通信链路可以包括上行链路、下行链路以及侧行链路中的一种或多种。
另一方面,第一侧行链路是第一终端设备与第二终端设备通信使用的链路,因此,在确定第二终端设备期望配置的载波时可以考虑第一终端设备的载波情况。例如,第二终端设备期望的载波可以基于第一终端设备的终端能力支持的载波确定的。又例如,第二终端设备期望的载波还可以基于第一终端设备的空闲的载波确定。本申请实施例对此不作限定。
上述第一终端设备的载波情况可以由第一终端设备发送给第二终端设备。在一些实现方式中,当第一终端设备向第二终端设备请求第一配置辅助信息(详细参见下文介绍的触发方式3)时,第一终端设备可以在请求中携带第一终端设备的载波情况。当然,第一终端设备也可以通过其他信息向第二终端设备发送第一终端设备的载波情况。本申请实施例对此不作限定。
需要说明的是,如上文介绍,第二终端设备可以分别基于第二终端设备的载波情况或者第一终端设备的载波情况,确定第二终端设备期望配置的载波。当然,也可以综合考虑第一终端设备的载波情况和第二终端设备的载波情况,确定第二终端设备期望的载波,本申请实施例对此不作限定。
另外,在本申请实施例中,第一配置辅助信息中可以通过携带第二终端设备期望配置的载波的指示信息(例如,可以是载波的标识、载波的序号等),来指示第二终端设备期望配置的载波。本申请实施 例对指示第二终端设备期望配置的载波的具体方式不作限定。
在另一些实现方式中,上述第一配置辅助信息可以包括第二终端设备的终端能力支持的载波。通常,第二终端设备的终端能力支持的载波可以理解为是第二终端设备可用的载波。
在本申请实施例中,第一配置辅助信息中可以通过携带终端能力支持的载波的指示信息,来指示上述终端能力支持的载波。本申请实施例对指示终端能力支持的载波的具体方式不作限定。
上文介绍了第一配置辅助信息的内容,下文介绍发送第一配置辅助信息的触发方式。在本申请实施例中对第一配置辅助信息的触发方式不作限定。下文介绍几种常见的触发方式。
触发方式1,第一配置辅助信息的发送可以是周期性触发的。
也就是说,第二终端设备可以时间上的周期性的发送第一配置辅助信息。其中,周期性触发时使用的周期可以是通过预定义、预配置、网络配置等方式配置的,本申请实施例对此不作限定。
需要说明的是,如果第一终端设备不具有载波聚合能力,但是第二终端设备仍然周期性地向第一终端设备发送第一配置辅助信息,此时,第一配置辅助信息对于第一终端设备而言是无用的,那么周期性的发送第一配置辅助信息可能导致传输资源的浪费。因此,周期性的触发方式通常是在确定第一终端设备具有载波聚合能力的情况下,使用的一种触发方式。当然,如果不考虑传输资源浪费的问题,在使用周期性的触发方式时,也可以不考虑第一终端设备是否具有载波聚合能力。
另外,第一终端设备是否具有载波聚合能力,可以由第二终端设备向第一终端设备请求,或者,第一终端设备也可以主动告知第二终端设备,本申请实施例对此不作限定。
触发方式2,第一配置辅助信息的发送可以是基于事件触发的。
也就是说,如果发生事件时,则第二终端设备便会向第一终端设备发送第一配置辅助信息。相反地,如果没有发生上述事件,则第二终端设备便不会向第一终端设备发送第一配置辅助信息。其中,事件可以是通过预定义、预配置、网络设备配置等方式配置的,本申请实施例对此不作限定。
需要说明的是,如果第一终端设备不具有载波聚合能力,但是在发生上述事件的情况下,第二终端设备仍然周期性地向第一终端设备发送第一配置辅助信息,此时,第一配置辅助信息对于第一终端设备而言是无用的,那么基于事件触发第一配置辅助信息的发送,可能导致传输资源的浪费。因此,基于事件的触发方式通常是在确定第一终端设备具有载波聚合能力的情况下,使用的一种触发方式。当然,如果不考虑传输资源浪费的问题,在使用基于事件的触发方式时,也可以不考虑第一终端设备是否具有载波聚合能力。
在本申请实施例中,上述事件可以基于导致第二终端设备的载波使用情况发生变化的场景相关,下文以几种可能的事件为例进行介绍。
在一些场景中,当第一侧行链路的链路质量发生变化后,该第一侧行链路上使用的载波也会发生变化。例如,当第一侧行链路的链路质量变差时,第二终端设备可能不再使用第一侧行链路上的载波,导致第二终端设备在第一侧行链路上可用的载波发生变化。因此,上述事件可以与第一侧行链路的链路质量关联。在一些实现方式中,上述事件可以包括第一侧行链路的链路质量变化。其中,链路质量变化例如可以包括链路质量变差。
在一些场景中,当通信链路之间发生冲突后,第二终端设备可能不再使用发生冲突的通信链路,此时,对于发生冲突的通信链路上的载波而言,第二终端设备可能不再使用,或者,第二终端设备会在第一侧行链路上使用该载波,最终无论第二终端设备是否使用该载波,都可能导致第二终端设备在第一侧行链路上的可用的载波发生变化,因此,上述事件可以与第一侧行链路与其他通信链路之间存在冲突关联。在一些实现方式中,上述事件可以包括第一侧行链路与其他通信链路之间存在冲突。
在一些场景中,第二终端设备期望配置的载波会因为种种原因发生变化,当第二终端设备期望配置的载波发生变化时,在配置第一侧行链路上使用的载波时需要考虑第二终端设备期望配置的载波的变化,因此,上述事件可以与第二终端设备期望配置的载波发生变化关联。在一些实现方式中,上述事件可以包括第二终端设备期望配置的载波发生变化。
在一些场景中,由于种种原因,配置辅助信息会发生变化。例如,上文介绍的当第二终端设备期望配置的载波发生变化后,配置辅助信息也会发生变化。相应地,在配置第一侧行链路上使用的载波时需要考虑配置辅助信息的变化,因此,上述事件可以与配置辅助信息发生变化关联。在一些实现方式中,上述事件可以包括第一配置辅助信息相比于之前发送的配置辅助信息发生变化,其中,配置辅助信息用于确定载波配置信息,或者说,配置辅助信息与第一配置辅助信息的功能相同。
在一些场景中,第二终端设备的除第一侧行链路之外的其他通信链路的载波配置会发生变化,当其他通信链路的载波配置发生变化后,可能会导致第二终端设备在第一侧行链路中可以使用的载波发生变化。因此,上述事件可以与第二终端设备中其他通信链路的载波配置发生变化关联。在一些实现方式中,上述事件可以包括第二终端设备的其他通信链路的载波配置发生变化。
当然,在本申请实施例中,上述事件除了与导致第二终端设备的载波使用情况发生变化的种种场景相关,上述事件还可以与配置辅助信息的传输情况相关。在一些实现方式中,上述事件可以包括第二终端设备未通过第一侧行链路发送过配置辅助信息,或者说,在发送第一配置辅助信息之前,第二终端设备未通过第一侧行链路发送过配置辅助信息。
触发方式3:第一配置辅助信息的发送可以是基于第一终端设备的请求触发。
也就是说,第一终端设备可以主动向第二终端设备发送请求,以请求第一配置辅助信息,相应地,响应于该请求,第二终端设备可以向第一终端设备发送第一配置辅助信息。
需要说明的是,本申请实施例对第一终端设备发送上述请求的时机不作限定。在一些实现方式中,第一终端设备可以在发送载波配置信息之前,向第二终端设备发送该请求。在另一些实现方式中,第一终端设备也可以在为第二终端设备配置第一侧行链路的载波失败后,向第二终端设备发送该请求。
需要说明的是,上述触发方式1~3可以单独使用,也可以相互结合使用,本申请实施例对此不作限定。
在一些场景中,第一终端设备和/或第二终端设备可能会位于网络设备的覆盖范围内,此时,如果第一终端设备直接为第二终端设备配置第一侧行链路使用的载波,可能导致第一侧行链路上配置的载波可能被网络设备分配给其他终端设备,导致第一侧行链路上配置的载波不合理。
例如,对于位于市区的网络设备而言,可能存在大量的业务数据需要传输,此时,网络设备通常并不希望将蜂窝通信使用的载波分配给侧行通信使用。此时,如果第一终端设备为第二终端设备配置的载波刚好是蜂窝通信使用的载波,可能导致蜂窝通信与侧行通信冲突。
因此,为了避免上述情况,在本申请实施例中,当第一终端设备或者第二终端设备位于网络覆盖范围内时,网络设备可以参与第一侧行链路的载波配置过程。当然,如果不考虑上述问题,在第一终端设备或者第二终端设备位于网络设备的覆盖范围内的情况下,第一终端设备也可以直接配置第一侧行链路的载波,而无需网络设备的参与。
下文分别结合第一终端设备位于网络覆盖范围内,或第二终端终端设备位于网络覆盖范围内,两种情况介绍网络设备参与载波配置的方案。
在情况1中,第一终端设备位于网络覆盖范围内。
此时,上述载波配置信息可以是基于网络设备确定的。例如,网络设备可以通过第一终端设备向第二终端设备配置第一侧行链路上使用的至少两个载波。或者说,网络设备可以向第一终端设备发送上述载波配置信息,相应地,第一终端设备将接收到的载波配置信息发送给第二终端设备。
在一些场景中,网络设备可能无法获知第二终端设备的载波情况,此时,网络设备针对第一侧行链路配置的载波,第二终端设备可能无法使用。因此,为了提高网络设备针对第一侧行链路配置的载波的合理性,第一终端设备可以将上文介绍的配置辅助信息发送给网络设备,以辅助网络设备确定载波配置信息。
需要说明的是,在本申请实施例中,第一终端设备可以直接将第二终端设备发送的配置辅助信息发送给网络设备,即,第一终端设备向网络设备发送第二配置辅助信息,其中,第二配置辅助信息与第一配置辅助信息(即第二终端设备向第一终端设备发送的配置辅助信息)相同。
当然,第一终端设备还可以在接收到第二终端设备发送的第一配置辅助信息后,对第一配置辅助信息进行处理得到第二配置辅助信息,并将第二配置辅助信息发送给网络设备。此时,第二配置辅助信息与第一配置辅助信息不同。其中,第二配置辅助信息可以是基于第一配置辅助信息确定的,或者说,第二配置辅助信息用于指示第一配置辅助信息。
例如,假设第一配置辅助信息包括第二终端设备的终端能力支持的载波,当第一终端设备接收到第一配置辅助信息后,可以在第一配置辅助信息中添加第一终端设备的终端能力支持的载波,以得到第二配置辅助信息,然后,第一终端设备可以将第二配置辅助信息发送给网络设备。
相应地,在第二终端设备接收到载波配置信息后,第二终端设备可以选择接受载波配置信息中的部分或全部配置信息,或者,第二终端设备可以选择拒绝接受载波配置信息中的部分或全部配置信息。此时,第二终端设备可以将上述选择结果通过第一指示信息告知第一终端设备,以便后续第一终端设备确定是否基于载波配置信息配置的载波与第二终端设备通信。
在一些实现方式中,上述第一指示信息可以承载于配置完成消息或配置失败消息中。其中,配置完成消息用于指示针对第一侧行链路的载波配置过程完成。配置失败消息用于指示针对第一侧行链路的载波配置过程失败。
需要说明的是,当第一指示信息指示拒绝接受载波配置信息时,且第一指示信息承载于配置完成消息,此时,可以理解针对第一侧行链路的配置过程完成,对于除了载波配置之外的配置参数配置成功或部分成功,但第一侧行链路上的载波并未配置成功。
另外,当第一指示信息指示接受载波配置信息时,且第一指示信息承载于配置失败消息,此时,可以理解针对第一侧行链路的载波配置过程失败。
在另一些实现方式中,第一终端设备还可以将上述选择结果告知网络设备,以便网络设备确定是否重新针对第一侧行链路配置载波。因此,第一终端设备可以向网络设备发送第二指示信息,以指示第二终端设备接受载波配置信息中的部分或全部配置信息,或指示第二终端设备拒绝接受载波配置信息中的部分或全部配置信息。
需要说明的是,上述第二指示信息可以与第一指示信息是相同的信息,也就是说,第一终端设备直接将第一指示信息转发给了网络设备。当然,上述第二指示信息与第一指示信息也可以是不同的信息,即第二指示信息可以用于指示第一指示信息,或者说,第二指示信息是基于第一指示信息的确定的。也就是说,第一终端设备在接收到第一指示信息后,对第一指示信息进行了处理,得到第二指示信息,并将第二指示信息发送给网络设备。
在上述情况1中,对于处于网络设备覆盖范围内的第一终端设备而言,第一终端设备可以处于连接态,此时,第一终端设备的资源分配模式可以包括上文介绍的模式1或模式2。当然,上述网络设备辅助的载波配置过程可以仅限于资源分配模式处于模式1的第一终端设备。
在上述情况1中,第二终端设备可以不位于网络设备的覆盖范围内,或者说,第二终端设备位于网络设备的覆盖范围之外,即上文结合图3所示的场景。当然,在上述情况1中,第二终端设备也可以位于网络设备的覆盖范围内,本申请实施例对此不作限定。
在情况2中,第二终端设备位于网络设备的覆盖范围内。
此时,第二终端设备可以向网络设备发送载波配置信息,相应地,网络设备可以通过第一指示信息指示第二终端设备接受载波配置信息中的部分或全部配置信息,或,网络设备可以指示第二终端设备拒绝接受载波配置信息中的部分或全部配置信息。
例如,网络设备确定载波配置信息中的载波空闲时,可以通过第一指示信息,指示第二终端设备接受载波配置信息。相反地,网络设备确定载波配置信息中的载波被蜂窝通信占用时,可以通过第一指示信息,指示第二终端设备拒绝接受载波配置信息。
通常,在网络设备通过第一指示信息向第二终端设备指示了载波配置信息的配置结果后,第一终端设备也需要知道载波配置信息的配置结果,以便后续确定是否基于载波配置信息配置的载波与第二终端设备通信,因此,第二终端设备可以向第一终端设备发送第一指示信息。
在一些实现方式中,上述第一指示信息可以承载于配置完成消息或配置失败消息中。其中,配置完成消息用于指示针对第一侧行链路的载波配置过程完成。配置失败消息用于指示针对第一侧行链路的载波配置过程失败。
需要说明的是,当第一指示信息指示拒绝接受载波配置信息时,且第一指示信息承载于配置完成消息,此时,可以理解针对第一侧行链路的载波配置过程完成,但第一侧行链路上的载波并未配置成功。
另外,当第一指示信息指示接受载波配置信息时,且第一指示信息承载于配置失败消息,此时,可以理解针对第一侧行链路的载波配置过程失败,但配置过程的失败原因并不是因为第二终端设备拒绝接受载波配置信息导致的。
在上述情况2中,对于处于网络设备覆盖范围内的第二终端设备而言,第二终端设备可以处于连接态,此时,第二终端设备的资源分配模式可以包括上文介绍的模式1和模式2。
在上述情况2中,第一终端设备是否处于网络设备的覆盖范围内并不做限定。例如,第一终端设备可以不位于网络设备的覆盖范围内,或者说,第一终端设备位于网络设备的覆盖范围之外,即上文结合图3所示的场景。当然,在上述情况2中,第一终端设备也可以位于网络设备的覆盖范围内,本申请实施例对此不作限定。
在一些实现方式中,若第二终端设备拒绝接受载波配置信息中的部分或全部配置信息,和/或,第二终端设备向第一终端设备发送了配置失败消息,第一终端设备和/或第二终端设备执行以下一项或多项操作:确定第一侧行链路发生无线链路失败(radio link failure,RLF);断开第一侧行链路;以及重配置第一侧行链路的载波配置信息。
相反地,若第二终端设备接受载波配置信息中部分或全部配置信息后,第一终端设备可以基于第二终端设备接受的配置信息配置的载波,与第二终端设备通信。
在本申请实施例中,在上述针对第一侧行链路的配置信令交互完成之前,第一侧行链路上可以不基于载波聚合技术进行通信,也就是说,可以以单载波的方式在第一侧行链路上通信。当然,为了提高带宽,在上述针对第一侧行链路的配置信令交互完成之前,在第一侧行链路上也可以使用载波聚合技术进行通信。在这种情况下,参与载波聚合的载波可以是基于预配置信息配置的,或者,第一侧行链路上使用的载波可以是基于配置的业务与载波的映射规则确定的载波。其中,业务与载波的映射规则可以复用 LTE V2X中的映射关系。
例如,在第一终端设备向第二终端设备发送载波配置信息之前,第一侧行链路上使用的载波并没有被配置,但第一终端设备需要与第二终端设备基于载波聚合进行通信(例如,传输PC5-无线资源控制(PC5-radio resource control,PC5-RRC)信令(例如,PC5-S信令)、传输发现(discovery)消息、传输直连通信请求(direct communication request,DCR)等),此时,使用的载波可以是基于预配置信息配置的,和/或,可以是基于配置的业务与载波的映射规则确定的。
需要说明的是,终端设备选择上述载波集合的方式,可以采用传统的侧行链路中选择载波的方式选择。例如,可以如前文中介绍的基于CBR门限选择参与载波集合的载波,本申请实施例对此不作限定。
为了便于理解,下文结合图10至图11介绍本申请实施例的无线通信方法。在下文的介绍中,以第一终端设备为终端设备1,第二终端设备为终端设备2,且第一侧行链路为侧行链路1为例进行介绍。

在步骤S1110中,若终端设备1未配置侧行链路1中进行载波聚合使用的载波,终端设备1和终端设备2之间可以在第一侧行链路上基于载波集合进行载波聚合,并基于载波聚合进行通信。
上述载波集合可以是基于预配置信息配置的,和/或,可以是基于配置的业务与载波的映射规则确定的。其中,业务与载波的映射规则可以复用LTE V2X中的映射关系。
