Description

通信方法、装置及系统 技术领域
本申请涉及通信技术领域,尤其涉及可以支持新空口(new radio,NR)中多播业务传输的通信方法、装置及系统。
背景技术
在长期演进(long term evolution,LTE)系统中,小区的带宽较窄,小区内的所有终端设备都在该小区的带宽上工作。终端设备的各种业务例如单播或多播等都在该小区的带宽内传输。而在第五代移动通信技术(5th-Generation,5G)的NR技术中,小区的带宽较宽,不同终端设备的射频能力不同,所能支持的最大带宽不同,因此引入了带宽部分(bandwidth part,BWP)的概念,即,在一个小区宽带上为终端设备分配部分频谱使用,以适应终端设备所能支持的带宽。
然而,BWP的引入使得不同终端设备的工作带宽与小区的带宽不相同,不同终端设备可能对应不同的BWP。而多播业务传输需要不同终端设备同时接收相同的信号,因此NR中多播业务在小区带宽内如何传输是一个急需研究的问题。

具体实施方式
为了方便理解本申请实施例的技术方案,首先给出本申请相关技术的简要介绍如下。
带宽部分(bandwidth part,BWP):在5G的NR技术中,小区的带宽较宽,例如100MHz,一个终端设备需要使用的带宽往往有限,因此引入BWP,即在整个大的小区带宽内划出部分带宽给终端设备进行接入和数据传输,终端设备只需在为其划分的这部分带宽内进行相应的数据传输。另外,在NR中,终端设备的带宽可以动态的变化。例如,网络设备可以为终端设备配置多个不同的BWP,这些不同的BWP的带宽以及配置参数都可以不同。网络侧可以根据当前业务量,例如需要进行大数据量传输时候,将终端设备的活跃态BWP切换到大带宽的BWP。从而,通过引入BWP,可以有效利用小区的带宽资源。
组无线网络临时标识(group-radio network temporary identifier,G-RNTI):在终端设备组和网络设备之间的信号信息内部的作为不同终端设备组的标识。G-RNTI标识了网络设备对应的小区中的多播业务服务,每个G-RNTI可以关联一个多播业务服务,小区通过G-RNTI来同时向该G-RNTI对应的多播业务服务涉及的一个或多个终端设备调度业务数据。
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描述。其中,在本申请的描述中,除非另有说明,“/”表示前后关联的对象是一种“或”的关系,例如,A/B可以表示A或B;本申请中的“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况,其中A,B可以是单数或者复数。并且,在本申请的描述中,除非另有说明,“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a-b,a-c,b-c,或 a-b-c,其中a,b,c可以是单个,也可以是多个。另外,为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。
此外,本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案,并不构成对于本申请实施例提供的技术方案的限定,本领域普通技术人员可知,随着网络架构的演变和新业务场景的出现,本申请实施例提供的技术方案对于类似的技术问题,同样适用。
如图1所示,为本申请实施例提供的一种通信系统10。该通信系统10包括一个网络设备11,以及与该网络设备11连接的一个或多个终端设备12。其中,终端设备12为网络设备11覆盖的小区13内的终端设备。
参见图1,在多播场景下,网络设备11可以通过G-RNTI来同时向多个终端设备12调度多播业务数据,每个G-RNTI可以关联一个多播业务服务。例如,多播业务服务可以包括电视广播、直播或更新软件版本等。通常,网络设备使用一个多播业务服务对应的G-RNTI对该多播业务数据进行加扰并发送给需要该多播业务服务的终端设备(例如,图1所示的多播业务服务110中的终端设备12),终端设备接收到该多播业务服务数据后,使用G-RNTI对该多播业务数据进行解扰。从而,不同的G-RNTI可以对应于不同的多播业务服务,如图1所示,G-RNTI 1对应于多播业务服务110,G-RNTI 2对应于多播业务服务120。
在NR技术中,网络设备可以为其对应小区内的各个终端设备分别配置一个或多个BWP。终端设备可以为用户设备(user equipment,UE)、接入设备等。示例性地,终端设备可以包括UE1和UE2。其中,参见图2,UE1和UE2可以分别具有网络设备为其配置的一个或多个BWP。
在本申请的一些实施例中,参见图2,假设网络设备需要向UE1和UE2传输多播业务a,UE1的一个或多个BWP中的活跃态BWP与UE2的一个或多个BWP中的活跃态BWP覆盖公共带宽b(即,图2所示的阴影区域),使用该公共带宽b来传输该多播业务a。其中,活跃态BWP为一个或多个BWP中的被激活生效的BWP;通常,一个UE一次最多有一个BWP生效。在该方案中,小区使用UE1的活跃态BWP与UE2的活跃态BWP存在重叠的小区带宽区域来进行多播业务的传输。
上述方案提出了一种NR中多播业务数据在小区带宽内传输的解决方案。在上述方案中,由于UE1或UE2的单播业务传输和多播业务传输使用相同的活跃态BWP,而一个BWP对应一种配置参数,因此,在UE1或UE2同时接收单播业务数据和多播业务数据时,单播业务数据传输和多播业务数据传输使用相同的配置参数。并且,为了确保UE1和UE2都能正确解读传输多播业务a的公共带宽b,UE1的活跃态BWP和UE2的活跃态BWP也需要有相同的配置参数,使得UE1和UE2在活跃态BWP内的单播数据传输也使用相同的配置参数。从而,在该方案中,网络设备需要为UE1和UE2配置具有相同配置参数的活跃态BWP,无法灵活调节配置参数,可能会影响单播数据传输的效率。
示例性地,配置参数可以包括子载波间隔(sub-carrier space,SCS)或循环前缀(cyclic prefix,CP)长度等。以下具体说明配置参数对单播数据传输效率的影响。
在5G NR中,通常,无线帧和子帧的长度是固定的。无线帧长度为10ms,无线帧包括10个子帧,每个子帧长度为1ms。每个子帧包括多个时隙。在正常CP情况下,每个时隙包含的正交频分复用(orthogonal frequency division multiplexing,OFDM)符号数相同,且都为14个。同时,SCS与OFDM符号长度之间具有倒数关系;即,若SCS较小,则OFDM符号长度较长;若SCS较大,则OFDM符号长度较短。SCS不同,OFDM符号长度不同,每个时隙的长度不同,相应地,每个子帧中可以包括的时隙数量不同,每个子帧携带的数据量不同,因此,SCS不同,会使得数据传输效率不同。对于单播业务数据传输有高速率需求的终端设备,需要适配较大的SCS,而上述为UE1和UE2配置具有相同配置参数的活跃态BWP的方案,无法灵活调节配置参数,可能会影响单播数据传输的效率。
类似地,CP是将OFDM符号尾部的一段数据复制到该OFDM符号的前面形成的循环结构,CP会消耗总的传输资源。可以理解,CP长度越长,CP消耗的传输资源越多,从而数据传输的效率越低。对于单播业务数据传输有高速率需求的终端设备,需要适配较短的CP长度,而上述为UE1和UE2配置具有相同配置参数的活跃态BWP的方案,无法灵活调节配置参数,可能会影响单播数据传输的效率。
在本申请的另一些实施例中,参见图3,网络设备为每个多播业务配置有专门的BWP,假设网络设备需要向对应小区内的UE1和UE2传输多播业务a,小区可以使用用于传输多播业务a的BWP进行该多播业务数据的传输。同时,UE1和UE2可以分别具有网络设备为其配置的一个或多个BWP,UE1和UE2的单播业务在网络设备为其配置的一个或多个BWP中的活跃态BWP上传输。
也就是说,一方面,网络设备为多播业务传输配置了独立的BWP,使得UE的单播业务和多播业务工作在两个BWP上,从而小区可以分别通过两个BWP灵活调度单播业务和多播业务,使得多播BWP和单播BWP可以具有不同的配置参数,减少了多播数据传输对单播数据传输效率的影响。另一方面,由于使用独立的BWP传输多播业务数据,无需像图2所示的方案中那样使用UE1的活跃态BWP与UE2的活跃态BWP存在重叠的小区带宽区域进行多播业务的传输;因此,在同时传输多播业务和单播业务时,UE1的活跃态BWP、UE2的活跃态BWP也可以具有不同的配置参数,从而可以灵活调节UE1的活跃态BWP和UE2的活跃态BWP的配置参数,进一步减少了多播数据传输对单播数据传输效率的影响。
其中,图2和图3以多播业务a对应的终端设备是两个UE(即UE1和UE2)为例对本申请的实施例进行了说明。可以理解,多播业务还包括对应更多个UE的多播业务,本申请实施例对此不作限定。
另外,图3示例性示出的UE1的活跃态BWP、UE2的活跃态BWP以及用于多播业务a的BWP的带宽区域无重叠,但是在本申请的实施例中,UE1的活跃态BWP、UE2的活跃态BWP以及用于多播业务a的BWP的带宽区域也可以重叠,本申请实施例对UE1的活跃态BWP、UE2的活跃态BWP以及多播BWP的带宽区域不作限定。

可选的,本申请实施例中,图1或图4所示的网络设备与终端设备也可以称之为通信装置,其可以是一个通用设备或者是一个专用设备,本申请实施例对此不作具体限定。
下面将结合图1和图4,对本申请实施例提供的通信方法进行展开说明。
需要说明的是,本申请实施例中的通信方法分别通过两个BWP灵活调度单播业务和多播业务,可用于NR场景下单播业务和多播业务的传输,在此统一说明,以下不再赘述。
以图1所示的网络设备与任一终端设备进行交互为例,如图5所示,为本申请实施例提供的一种通信方法,该方法包括如下步骤:
501、网络设备向终端设备发送第一小区支持的多播业务列表,第一小区为所述网络设备提供服务的小区。
其中,第一小区为所述网络设备提供服务的小区,但是网络设备提供服务的小区并不限于第一小区,例如,网络设备还可以为其他一个或多个小区提供服务。
另外,多播业务列表可以包括至少一个多播业务的第一信息,第一信息包括多播业务的标识和用于传输多播业务的BWP。例如,多播业务可以包括电视广播、直播、或更新软件版本等。用于传输多播业务的BWP与多播业务相对应,即,不同的多播业务可以对应不同的BWP。可以理解的是,至少一个多播业务的第一信息还可以包括与多播业务相关的其他内容,本申请实施例对此不作限定。
由于每个多播业务可以对应一种BWP配置信息,每种BWP配置信息可以对应一个BWP标识。因此,在一些实现方式中,用于传输多播业务的BWP可以包括与该BWP对应的BWP标识,即,用于传输多播业务的BWP可以通过相应的BWP标识来指示。或者,在另一些实现方式中,用于传输多播业务的BWP可以包括与该BWP对应的BWP配置信息,即,用于传输多播业务的BWP可以通过相应的BWP配置信息来指示。
示例性地,网络设备可以预先为多播业务列表中的每个多播业务配置相应的BWP。例如,在终端设备与网络设备建立连接(即,终端设备进入连接态)之前,网络设备就可以为多播业务列表中的每个多播业务配置相应的BWP。其中,连接态是终端设备所处的一种状态,通常,终端设备可以处于空闲态或连接态。当终端设备在某个小区完成了驻留之后,可以称该终端设备进入了空闲态。若该终端设备后续又完成了随机接入过程,并与网络建立了连接,则可以称该UE进入了连接态。
示例性地,网络设备可以通过系统广播消息向终端设备发送第一小区支持的多播业务列表。可以理解的是,除了系统广播消息之外,网络设备还可以通过其他方式向终端设备发送第一小区支持的多播业务列表,本申请实施例对此不作限定。
502、终端设备根据多播业务列表确定第一多播业务。
其中,第一多播业务可以为终端设备感兴趣的多播业务。也就是说,终端设备可以根据从网络设备接收到的多播业务列表,从该多播业务列表中确定感兴趣的多播业务。
503、终端设备向网络设备发送第一多播业务的标识,第一多播业务的标识包含于多播业务列表。
在终端设备进入连接态之后,终端设备可以向网络设备发送终端设备根据多播业务列表确定的第一多播业务的标识。根据前述可知,多播业务列表可以包括至少一个多播业务的第一信息,第一信息包括多播业务的标识,从而,第一多播业务的标识包含于多播业务列表中。
504、终端设备还向网络设备发送第一指示信息,第一指示信息用于指示终端设备是否支持同时接收两个BWP的业务数据。
其中,该两个BWP中的一个BWP用于接收单播业务数据,两个BWP中的另一个BWP用于接收多播业务数据。也就是说,终端设备向网络设备发送第一指示信息,即为,终端设备向网络设备上报终端设备是否支持同时在一个BWP接收单播业务数 据并且在另一个BWP接收多播业务数据的能力。因此,第一指示信息也可以称为能力指示信息。
在一些实现方式中,终端设备可以支持同时接收两个BWP的业务数据。此时,第一指示信息还可以用于指示以下中至少一项:终端设备是否要求两个BWP的频带范围在预设范围内,终端设备是否支持两个BWP具有不同的SCS配置,或者终端设备是否支持两个BWP具有不同的CP长度配置等。
可见,上述各项为终端设备是否支持同时分别在两个BWP上接收单播业务数据和多播业务数据的能力的具体体现。可以理解的是,终端设备是否支持同时分别在两个BWP接收单播业务数据和多播业务数据的能力的具体体现不限于上述各项的示例,还可以存在其他类型的指示终端设备是否支持同时分别在两个BWP接收单播业务数据和多播业务数据的能力的具体体现的示例,本申请对此不作限定。
示例性地,终端设备是否要求两个BWP的频带范围在预设范围内,可以包括:终端设备是否要求两个BWP的频带范围所涵盖的带宽范围在终端设备的接收机的带宽范围内。例如,若终端设备支持同时在两个BWP上分别接收单播业务数据和多播业务数据,终端设备的接收机的带宽范围为30M,用于传输多播业务a的BWP的带宽为10M,则用于传输单播业务的BWP的带宽与用于传输多播业务a的BWP的带宽在小区带宽内所涵盖的带宽范围需要在30M之内。否则,若用于传输单播业务的BWP的带宽与用于传输多播业务a的BWP的带宽在小区带宽内所涵盖的带宽范围超出30M的带宽范围,则终端设备的接收机就可能无法同时接收到多播业务a和单播业务。
在另一些实现方式中,终端设备可能不支持同时接收两个BWP的业务数据。此时,终端设备无法在两个BWP上同时接收多播业务和单播业务,因此,第一BWP和第二BWP之间彼此独立,网络设备可以仅根据第一指示信息所指示的终端设备的能力来确定第二BWP。另外,若终端设备指示多播业务优先,则网络设备可以暂停终端设备在单播BWP上的单播业务数据的传输,优先在多播BWP上传输多播业务数据。
在终端设备支持同时接收两个BWP的业务数据的情况下,该方法还可以包括:
505、网络设备根据第一多播业务的标识确定第一BWP,第一BWP为用于传输第一多播业务的BWP;网络设备根据第一BWP和第一指示信息,确定第二BWP,第二BWP为用于传输单播业务的BWP。
也就是说,网络设备可以根据终端设备上报的感兴趣的第一多播业务的标识确定用于传输第一多播业务的第一BWP,并且根据第一BWP和来自终端设备的能力指示信息,确定用于传输单播业务的第二BWP。
示例性地,第一BWP与第二BWP可以不同,可以包括:第一BWP与第二BWP的频带范围不同,或者,第一BWP与第二BWP的配置参数不同。
其中,第一BWP与第二BWP的频带范围不同,具体可以包括:第一BWP与第二BWP的频带范围不重叠或者部分重叠。第一BWP与第二BWP的配置参数不同,具体可以包括:第一BWP与第二BWP的SCS配置不同;和/或,第一BWP与第二BWP的CP长度配置不同。
可选地,在终端设备的能力支持的情况下,第一BWP和第二BWP也可以共享相同的频带范围和配置参数。此时,虽然第一BWP和第二BWP的频带范围和配置参数 相同,但是其接收逻辑不同,仍然是两个不同的BWP。
在步骤501至步骤505描述的方案中,网络设备先向终端设备发送多播业务列表;然后,终端设备根据该多播业务列表确定感兴趣的第一多播业务,向网络设备发送第一多播业务的标识,并且向网络设备上报第一指示信息,以向网络设备指示终端设备的能力;从而,网络设备可以根据第一多播业务的标识确定用于传输多播业务的第一BWP,并且根据第一BWP和第一指示信息,确定用于传输单播业务的第二BWP。因此,网络设备可以根据终端设备上报的感兴趣的多播业务的标识以及能力指示信息,确定用于传输单播业务的BWP以及用于传输多播业务的BWP,使得终端设备的单播业务和多播业务工作在两个BWP上,从而小区可以分别通过两个BWP灵活调度单播业务和多播业务。
另外,网络设备为多播业务传输专门配置了相应的多播BWP,网络设备可以根据感兴趣的多播业务对应的多播BWP以及终端设备的能力指示信息,为终端设备灵活配置单播BWP。相比于图2所示的多播业务在小区带宽内传输的方案,在终端设备的能力允许的前提下,网络设备可以为单播BWP与多播BWP设置不同的配置参数(SCS或CP长度等),从而网络设备可以灵活调节单播BWP与多播BWP的配置参数,减少对单播数据传输效率的影响。
示例性地,根据上述可知,第一指示信息还可以用于指示要求两个BWP的频带范围在预设范围内,此时,网络设备可以确定第一BWP与第二BWP的频带范围在预设范围内。
也就是说,若终端设备的能力指示要求两个BWP的频带范围在预设范围内,则网络设备可以确定第一BWP与第二BWP的频带范围在预设范围内。
再示例性地,第一指示信息还可以用于指示支持两个BWP具有不同的SCS配置,此时,网络设备确定第一BWP与第二BWP具有不同的SCS配置。
也就是说,若终端设备的能力指示支持两个BWP具有不同的SCS配置,则网络设备可以确定第一BWP与第二BWP具有不同的SCS配置,从而可以减少对单播数据传输效率的影响。
再示例性地,第一指示信息还可以用于指示支持两个BWP具有不同的CP长度配置,此时,网络设备确定第一BWP与第二BWP具有不同的CP长度配置。
也就是说,若终端设备的能力指示支持两个BWP具有不同的CP长度配置,则网络设备可以确定第一BWP与第二BWP具有不同的CP长度配置,从而可以减少对单播数据传输效率的影响。
在本申请的一些实现方式中,网络设备预先没有为终端设备配置用于传输单播业务的单播BWP。网络设备根据第一BWP和第一指示信息,确定第二BWP,即为:网络设备根据第一BWP和第一指示信息,为终端设备初次配置用于传输单播业务的第二BWP。之后,网络设备可以将活跃态单播BWP设置为该第二BWP,以使终端设备在该第二BWP上接收单播业务数据。
在本申请的另一些实现方式中,网络设备预先为终端设备配置有用于传输单播业务的单播BWP。示例性地,参见图5,在网络设备从终端设备接收第一多播业务的标识之前,即,步骤503之前,该方法还可以包括:
506、网络设备为终端设备配置至少一个单播BWP。
此时,由于网络设备为终端设备预先配置有至少一个单播BWP,因此,网络设备根据第一BWP和第一指示信息确定第二BWP时,首先需要根据第一BWP和第一指示信息确定预先配置的至少一个单播BWP中是否存在第二BWP,使得:终端设备可以同时在该第二BWP上接收单播业务数据并且在第一BWP上接收多播业务数据。
在一些实现方式中,网络设备可能根据第一BWP和第一指示信息,确定网络设备为终端设备预先配置的至少一个单播BWP中存在第二BWP。此时,网络设备根据第一BWP和第一指示信息确定第二BWP,可以包括:网络设备根据第一BWP和第一指示信息,确定至少一个单播BWP中的一个BWP为第二BWP,网络设备将活跃态单播BWP设置为第二BWP。例如,网络设备为终端设备预先配置了4个单播BWP,分别为BWP1,BWP2,BWP3和BWP4。然后,网络设备根据第一BWP和第一指示信息确定预先配置的4个BWP中的BWP3为符合要求的第二BWP,而终端设备的活跃态单播BWP为BWP1,则网络设备可以将活跃态单播BWP切换至BWP3。
在另一些实现方式中,网络设备可能根据第一BWP和第一指示信息,确定网络设备为终端设备预先配置的至少一个单播BWP中不存在第二BWP。此时,网络设备根据第一BWP和第一指示信息确定第二BWP,可以包括:网络设备根据第一BWP和第一指示信息,确定至少一个单播BWP中未包括第二BWP,网络设备根据第一BWP和第一指示信息重新配置第二BWP,并将活跃态单播BWP设置为第二BWP。例如,网络设备为终端设备预先配置了4个单播BWP,分别为BWP1,BWP2,BWP3和BWP4。然后,网络设备根据第一BWP和第一指示信息确定预先配置的4个BWP中没有符合要求的第二BWP,则网络设备可以根据第一BWP和第一指示信息重新配置第二BWP,并将活跃态单播BWP设置为第二BWP。
也就是说,在网络设备预先为终端设备配置有用于传输单播业务的单播BWP时,网络设备需要根据第一BWP和第一指示信息确定该预先配置的单播BWP中是否存在第二BWP。若预先配置的单播BWP中存在第二BWP,则网络设备将活跃态单播BWP设置为该第二BWP;若预先配置的单播BWP中不存在第二BWP,则网络设备根据第一BWP和第一指示信息重新配置第二BWP,并将活跃态单播BWP设置为该第二BWP。
以图1所示的网络设备与任一终端设备进行交互为例,如图6所示,为本申请实施例提供的另一种通信方法,该方法包括如下步骤:
601、网络设备向终端设备发送第一小区支持的多播业务列表以及网络设备为终端设备配置的至少一个单播BWP。
其中,第一小区为网络设备提供服务的小区,但是网络设备提供服务的小区并不限于第一小区,例如,网络设备还可以为第二小区或第三小区等其他小区提供服务。
另外,多播业务列表包括至少一个多播业务的第一信息,第一信息包括多播业务的标识和用于传输多播业务的BWP。其中,网络设备可以预先为多播业务列表中的每个多播业务配置相应的BWP。例如,在终端设备进入连接态之前,网络设备就可以为多播业务列表中的每个多播业务配置相应的BWP。
示例性地,网络设备可以通过系统广播消息向终端设备发送第一小区支持的多播业务列表以及网络设备为终端设备配置的至少一个单播BWP。可以理解的是,除了系 统广播消息之外,网络设备还可以通过其他方式向终端设备发送第一小区支持的多播业务列表以及网络设备为终端设备配置的至少一个单播BWP,本申请实施例对此不作限定。
也就是说,网络设备向终端设备发送为网络设备提供服务的第一小区支持的多播业务列表以及网络设备为终端设备预先配置的至少一个单播BWP。
602、终端设备根据多播业务列表确定第一多播业务。
其中,第一多播业务可以为终端设备感兴趣的多播业务。也就是说,终端设备可以根据从网络设备接收到的多播业务列表,从该多播业务列表中确定感兴趣的多播业务。示例性地,步骤602可以与图5所示的步骤502相同。
603、终端设备根据第一多播业务对应的第一BWP和终端设备的能力确定第二BWP。
其中,第一BWP为用于传输第一多播业务的BWP,第二BWP为至少一个单播BWP中的用于传输单播业务的BWP。
终端设备的能力,可以包括以下至少一项:终端设备是否支持同时接收两个BWP的业务数据;终端设备是否支持两个BWP中的一个BWP用于接收单播业务数据,两个BWP中的另一个BWP用于接收多播业务数据;终端设备是否要求两个BWP频带范围在预设范围内;终端设备是否支持两个BWP具有不同的子载波间隔SCS配置;或终端设备是否支持两个BWP具有不同的循环前缀CP长度配置等。
在一些实现方式中,终端设备的能力可以支持同时接收两个BWP的业务数据。进一步地,终端设备的能力,可以包括:终端设备是否支持两个BWP中的一个BWP用于接收单播业务数据,两个BWP中的另一个BWP用于接收多播业务数据;终端设备是否要求两个BWP频带范围在预设范围内;终端设备是否支持两个BWP具有不同的子载波间隔SCS配置;或终端设备是否支持两个BWP具有不同的循环前缀CP长度配置。
示例性地,若终端设备要求两个BWP的频带范围在预设范围内,则第一BWP与第二BWP的频带范围可以在预设范围内。
也就是说,若终端设备的能力指示要求两个BWP的频带范围在预设范围内,则第一BWP与终端设备确定的第二BWP的频带范围在预设范围内。
再示例性地,若终端设备支持两个BWP具有不同的SCS配置,则第一BWP与第二BWP可以具有不同的SCS配置。
也就是说,若终端设备的能力指示支持两个BWP具有不同的SCS配置,则第一BWP与终端设备确定的第二BWP可以具有不同的SCS配置,从而可以减少对单播数据传输效率的影响。
再示例性地,若终端设备的能力指示支持两个BWP具有不同的CP长度配置,则第一BWP与第二BWP可以具有不同的SCS配置。
也就是说,若终端设备的能力指示支持两个BWP具有不同的CP长度配置,则第一BWP与终端设备确定的第二BWP可以具有不同的CP长度配置,从而可以减少对单播数据传输效率的影响。
在另一些实现方式中,终端设备的能力可能不支持同时接收两个BWP的业务数 据。此时,终端设备无法在两个BWP上同时接收多播业务和单播业务,因此,第一BWP和第二BWP之间彼此独立,终端设备可以仅根据自身能力来确定第二BWP。另外,若终端设备指示多播业务优先,则网络设备可以暂停终端设备在单播BWP上的单播业务数据的传输,优先在多播BWP上传输多播业务数据。
根据上述可知,网络设备为终端设备预先配置有至少一个单播BWP,终端设备根据第一BWP和终端设备的能力确定第二BWP时,就是根据第一BWP和终端设备的能力确定预先配置的至少一个单播BWP中是否存在第二BWP,使得:终端设备可以同时在该第二BWP上接收单播业务数据并且在第一BWP上接收多播业务数据。
在本申请的一些实施例中,终端设备可能根据第一BWP和终端设备的能力,确定网络设备为终端设备预先配置的至少一个单播BWP中存在第二BWP。此时,该方法还可以包括:
604、终端设备向网络设备发送第一多播业务的标识和第二指示信息。
其中,第二指示信息用于指示终端设备能够同时在第一BWP上传播第一多播业务以及在第二BWP上传输单播业务,第二指示信息包括第二BWP的标识信息;第一多播业务的标识包含于多播业务列表。
也就是说,终端设备根据第一BWP和终端设备的能力,确定预先配置的至少一个单播BWP中存在第二BWP时,终端设备可以向网络设备发送第一多播业务的标识以向网络设备指示感兴趣的业务,并且向网络设备发送第二指示信息,以指示网络设备可以同时在第一BWP上接收第一多播业务数据并且在至少一个单播BWP中的第二BWP上接收单播业务数据。
在终端设备向网络设备发送第一多播业务的标识和第二指示信息后,网络设备可以从终端设备接收到第一多播业务的标识和第二指示信息,根据该第二指示信息,网络设备可以知晓预先配置的至少一个单播BWP中存在用于传输单播业务的第二BWP,从而,在步骤604之后,该方法还可以包括:
605、若网络设备从所述终端设备接收到第二指示信息,则网络设备将活跃态单播BWP设置为第二BWP。
在步骤601至步骤605所描述的方案中,网络设备向终端设备发送第一小区支持的多播业务列表以及网络设备为终端设备配置的至少一个单播BWP,终端设备可以根据多播业务列表确定第一多播业务,并且根据第一多播业务对应的第一BWP和终端设备的能力确定至少一个单播BWP中的用于传输单播业务的第二BWP。若终端设备确定预先配置的至少一个单播BWP中存在第二BWP,则终端设备可以向网络设备发送第一多播业务的标识和第二指示信息,网络设备接收到第一多播业务的标识和第二指示信息后,可以将活跃态单播BWP设置为该第二BWP。从而,终端设备可以根据感兴趣的第一多播业务对应的第一BWP以及自身能力,确定至少一个单播BWP中的用于传输单播业务的第二BWP,使得终端设备的单播业务和多播业务工作在两个BWP上,从而小区可以分别通过两个BWP灵活调度单播业务和多播业务。
另外,网络设备为多播业务传输专门配置了相应的多播BWP,终端设备可以根据感兴趣多播业务对应的多播BWP以及自身能力,确定至少一个单播BWP中用于传输单播业务的单播BWP,并向网络设备指示该单播BWP。相比于图2所示的多播业务 在小区带宽内传输的方案,在终端设备的能力允许的前提下,网络设备可以为单播BWP与多播BWP设置不同的配置参数(SCS或CP长度等),从而网络设备可以灵活调节单播BWP与多播BWP的配置参数,减少对单播数据传输效率的影响。
在本申请的另一些实施例中,终端设备可能根据第一BWP和终端设备的能力,确定网络设备为终端设备预先配置的至少一个单播BWP中不存在第二BWP。此时,参见图7,在步骤603之后,该方法还可以包括:
701、终端设备向网络设备发送第一多播业务的标识。
也就是说,终端设备根据第一BWP和终端设备的能力,确定网络设备为终端设备预先配置的至少一个单播BWP中不存在第二BWP时,终端设备可以仅向网络设备发送第一多播业务的标识。
在终端设备仅向网络设备发送第一多播业务的标识,而未向网络设备发送第二指示信息时,网络设备不会从终端设备接收到第二指示信息,网络设备可以根据该情况知晓预先配置的至少一个单播BWP中不存在第二BWP。从而,在步骤704之后,该方法还可以包括:
702、若网络设备未从终端设备接收到第二指示信息,则网络设备为终端设备重新配置至少一个单播BWP。
在步骤601至步骤603以及步骤701至步骤702所描述的方案中,网络设备向终端设备发送第一小区支持的多播业务列表以及网络设备为终端设备配置的至少一个单播BWP,终端设备可以根据多播业务列表确定第一多播业务,并且根据第一多播业务对应的第一BWP和终端设备的能力确定至少一个单播BWP中的用于传输单播业务的第二BWP。若终端设备确定预先配置的至少一个单播BWP中不存在第二BWP,则终端设备可以向网络设备发送第一多播业务的标识,网络设备接收到第一多播业务的标识后,可以为终端设备重新配置至少一个单播BWP。从而,终端设备可以根据感兴趣的第一多播业务的第一BWP以及自身能力,确定至少一个单播BWP中不存在第二BWP,并且为终端设备重新配置至少一个单播BWP,使得终端设备的单播业务和多播业务可以工作在不同的BWP上,从而小区可以分别通过两个不同的BWP灵活调度单播业务和多播业务。
另外,网络设备为多播业务传输专门配置了相应的多播BWP,终端设备可以根据感兴趣多播业务对应的多播BWP以及自身能力,确定至少一个单播BWP中不存在第二BWP,并使网络设备为终端设备重新配置至少一个单播BWP。相比于图2所示的多播业务在小区带宽内传输的方案,在终端设备的能力允许的前提下,网络设备可以为单播BWP与多播BWP设置不同的配置参数(SCS或CP长度等),从而网络设备可以灵活调节单播BWP与多播BWP的配置参数,减少对单播数据传输效率的影响。
可选地,终端设备根据第一BWP和终端设备的能力,确定网络设备为终端设备预先配置的至少一个单播BWP中不存在第二BWP时,终端设备可以向网络设备发送第一多播业务的标识以及第三指示信息,该第三指示信息可以用于指示网络设备为终端设备重新配置至少一个单播BWP。
也就是说,终端设备根据第一BWP和终端设备的能力,确定网络设备为终端设备预先配置的至少一个单播BWP中不存在第二BWP时,终端设备可以通过向网络设 备发送第三指示信息,指示网络设备为终端设备重新配置至少一个单播BWP。

804、网络设备根据第一多播业务的标识确定第一BWP,网络设备根据第一BWP和第一指示信息,确定第二BWP。
其中,第一BWP为用于传输第一多播业务的BWP,第二BWP为用于传输单播业务的BWP。
在上述通信方法中,网络设备可以根据终端设备上报的感兴趣的多播业务的标识以及能力指示信息,确定用于传输单播业务的BWP以及用于传输多播业务的BWP,使得终端设备的单播业务和多播业务工作在两个BWP上,从而小区可以分别通过两个BWP灵活调度单播业务和多播业务。另外,在上述通信方法中,例如,网络设备的操作可参考图5所示的实施例中网络设备的操作及上述相关文字说明,在此不再赘述。
此外,本申请实施例还公开了一种通信方法,应用于网络设备,如图9所示,该方法包括如下步骤901-步骤903:

在上述通信方法中,网络设备可以从终端设备接收第一多播业务的标识,并且还 可以从终端设备接收用于指示终端设备能够同时在第一BWP上传播第一多播业务以及在第二BWP上传输单播业务的第二指示信息。网络设备可以将活跃态单播BWP设置为该第二BWP,从而可以分别通过两个BWP灵活调度单播业务和多播业务。另外,在上述通信方法中,例如,网络设备的操作可参考图6所示的实施例中网络设备的操作及上述相关文字说明,在此不再赘述。
