在3GPP标准中针对每个频段分别定义了其所支持的带宽,如下表1所示,标准的带宽如5MHz、10MHz、15MHz…100MHz。终端设备需要支持这些带宽,用于与网络设备在一定带宽下通信。表1示出了NR频段(NR band),子载波间隔(Subcarrier spacing,SCS),UE信道带宽(Channel bandwidth)之间的关系。
表1
Figure PCTCN2020141051-appb-000001
其中,n3,n41表示频段号,YES表示对应的频段支持该带宽。
表1中的带宽对于上行频段和下行频段可以是相同的,也即上下行的带宽是对称的。另外对于有些频段,其对应的上行带宽和下行带宽定义是不对称的,比如表2所示,上行频段和下行频段分别支持了不同的带宽。此情况下,可以为每个上行带宽和下行带宽组合定义不同的不对称信道带宽组合集(Asymmetric channel bandwidth combination set),终端设备如果支持该频段,则至少需要支持其中的一个上/下行带宽集合,并将支持的带宽集合上报给网络设备。
表2
Figure PCTCN2020141051-appb-000002
其中,n66表示频段号。
在一些场景中,终端设备可以工作在多个频段上,该多个频段(以Band A和Band B为例)构成频段组合,每个频段都有各自支持的带宽,终端设备在该频段组合工作时可以引入带宽组合集(Bandwidth combination set)指示终端设备在该频段组合下每个频段支持的带宽。终端设备可以将支持的带宽组合集上报给网络设备。
在一些情况下,比如对于Band A,引入了带宽X,该带宽X可能是一个可选的带宽,并不是所有终端设备都需要去支持,如果直接将带宽X加入到已有的Bandwidth combination set中,会导致终端设备的不支持的问题。因此通常需要定义一个新的Bandwidth combination set来区分支持这个该带宽X及该带宽X与其他带宽的组合的终端,以及不支持该带宽X及该带宽X与其他带宽的组合的终端。这就需要支持这个带宽X的终端设备上报其在该Band A或Band A的频段组合下支持的信道带宽。
在实际应用中,终端设备需要不停的更新并支持该新定义的带宽及Bandwidth combination set并将支持的带宽和Bandwidth combination set上报给网络设备,同时网络设备也需要兼容不同的终端能力来判断其是否支持了新定义的带宽X及Bandwidth combination set以进行正确的配置。随着新引入的带宽及频段组合的增多,这种通过定义新的Bandwidth combination set来兼容这个新引入的带宽的方式使得终端设备和网络设备对支持的带宽组合的维护变得很困难。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图2是根据本申请实施例的无线通信的方法200的示意性交互图,如图2所示,该方法200包括如下内容:
S210,终端设备向网络设备发送第一信息,所述第一信息用于确定所述终端设备支持的最大带宽能力。
进一步可选地,在S220,所述网络设备可以根据所述第一信息对所述终端设备进行频段配置和/或带宽配置。
可选地,在一些实施例中,所述最大带宽能力可以包括最大信道带宽能力。
通过上报终端设备支持的最大带宽能力,这样,在引入新的带宽时,终端设备不必对新增的带宽进行能力的上报,网络设备基于终端设备支持的最大带宽能力对终端设备进行带宽配置,从而能够使得支持该带宽的终端设备前向兼容该新增的带宽。
以下,结合具体实施例,说明该第一信息的实现方式。
实施例1
在该实施例1中,该终端设备上报的最大带宽能力信息可以是不区分频段和频段组合的。
以下结合实施例1-1和实施例1-2说明具体的实现方式,但本申请并不限于此。
实施例1-1
可选地,在一些实施例中,所述第一信息包括至少一个最大带宽能力信息。
应理解,终端设备上报的最大带宽能力信息(记为MaxCBW),可以不同于已定义 的带宽,比如可以大于表1中的最大带宽100MHz。该最大带宽能力信息意味着只要网络设备配置的带宽小于等于该最大带宽能力信息MaxCBW,那么终端设备就可以支持该带宽,网络设备可以配置该带宽给终端设备使用。
举例说明,若终端设备上报的最大带宽能力信息MaxCBW为80MHz,那么当引入新的带宽70MHz时,网络设备可以给终端设备配置该70MHz的带宽,当引入新的带宽90MHz时,由于超过了终端设备的最大带宽能力信息MaxCBW,网络设备不能给终端设备配置该带宽。
因此,基于本申请实施例的上报方式可以实现已有终端前向兼容新引入的带宽(例如,比终端设备的最大带宽能力MaxCBW小的带宽),并且支持网络设备对该新增带宽的配置,同时降低了终端设备单独上报各个新引入的带宽是否支持的能力信息的信令开销。应理解,这里的已有终端可以是兼容(或者说,支持)新引入的带宽的终端设备。
可选地,所述至少一个最大带宽能力信息对应所述终端设备的所有频段和/或所有频段组合。即终端设备设备的最大带宽能力信息可以适用于所有频段和/或所有频段组合。

作为一个示例,所述第一信息可以包括第二最大带宽能力信息,该第二最大带宽能力信息可以适用于所有频段组合。
可选地,所述第一最大带宽能力信息和所述第二最大带宽能力信息可以是同一最大带宽能力信息,该同一最大带宽能力信息适用于所有频段以及所有频段组合。
可选地,在一些实施例中,所述至少一个最大带宽能力信息多个最大带宽能力信息,分别对应多个频段组,所述每个最大带宽能力信息对应一个频段组,其中,每个频段组包括至少一个频段。即终端设备可以以频段组为单位上报最大带宽能力信息。
可选地,在一些实施例中,所述第一信息可以包括以子载波间隔(Subcarrier spacing,SCS)粒度的最大带宽能力信息。例如,所述第一信息包括至少一个SCS中的每个SCS对应的最大带宽能力信息。
可选地,每个SCS对应的最大带宽能力信息可以相同或者也可以不同。
可选地,在一些实施例中,所述第一信息可以包括以上/下行粒度的最大带宽能力信息。例如,所述第一信息包括上行最大带宽能力信息和/或下行最大带宽能力信息。
应理解,在本申请实施例中,上行最大带宽能力信息和下行最大带宽能力信息可以相同或者也可以不同。
作为一个示例,所述第一信息包括第一上行最大带宽能力信息,所述第一上行最大带宽能力信息可以适用于所有的上行频段或上行频段组合。
作为另一个示例,所述第一信息包括第一下行最大带宽能力信息,所述第一下行最大带宽能力信息可以适用于所有的下行频段或下行频段组合。
可选地,在一些实施例中,所述第一信息可以包括SCS以及上下行粒度的最大带宽能力信息。
作为一个示例,所述第一信息可以包括上行最大带宽能力信息组和/或下行最大带宽能力信息组,该上行最大带宽能力信息组包括至少一个上行最大带宽能力信息,该至少一个上行最大带宽能力信息中的每个上行最大带宽能力对应一个SCS,该下行最大带宽能力信息组包括至少一个下行最大带宽能力信息,该至少一个下行最大带宽能力信息中的每个下行最大带宽能力对应一个SCS。
综上,在该实施例1-1中,终端设备上报的最大带宽能力信息可以是不区分频段和频频段组合的最大带宽能力,该不区分频段和频段组合的最大带宽能力可以是区分SCS和/或上下行的,或者也可以是不区分SCS和上下行的,本申请对此不作限定。
需要说明的是,在本申请实施例中,除非特别说明,本申请实施例中的最大带宽能 力信息都可以区分SCS和/或上下行,或者也可以不区分SCS和上下行。
可选地,在一些实施例中,若所述终端设备未上报所述终端设备支持的最大带宽能力信息,表示所述终端设备支持的最大带宽能力为默认值,例如,50MHz,或者所述终端设备不支持最大带宽能力上报。
实施例1-2
可选地,在一些实施例中,所述第一信息包括所述终端设备能够支持的所有带宽。
应理解,该终端设备能够支持的所有带宽可以包括终端设备的能力所能支持的带宽,该所有带宽可以包括未定义的带宽,例如,已定义的最大带宽为100MHz,若终端设备的能力可以支持120MHz,则该终端设备能够支持的所有带宽可以包括120MHz。
在一些实施例中,所述终端设备能够支持的所有带宽可以是不区分SCS的。
在另一些实施例中,所述终端设备能够支持的所有带宽也可以是以SCS为粒度的。
例如,所述第一信息可以包括在至少一个SCS中的每个SCS下终端设备支持的所有带宽。
在一些实施例中,所述终端设备能够支持的所有带宽可以是不区分上下行的。
在另一些实施例中,所述终端设备能够支持的所有带宽也可以是区分上下行的。
例如,所述第一信息可以包括终端设备在上行能够支持的所有带宽和/或终端设备在下行能够支持的所有带宽。
实施例1-3
该第一信息可以包括所述终端设备是否支持所有带宽的指示信息。
可选地,该所有带宽可以包括预定义的所有带宽,例如5MHz-50MHz。或者也可以包括标准中已定义的所有带宽,例如可以包括表1中的所有带宽。
实施例2
在该实施例2中,该终端设备可以以频段为粒度进行最大带宽能力信息的上报。
以下结合实施例2-1至实施例2-3说明具体的实现方式,但本申请并不限于此。
实施例2-1
可选地,在一些实施例中,所述第一信息包括所述终端设备在至少一个频段中的每个频段上的最大带宽能力信息。可选地,所述至少一个频段可以包括网络设备支持的频段中的部分或全部。
可选地,在一些实施例中,所述终端设备在所述每个频段上的最大带宽能力信息可以不区分SCS。
在另一些实施例中,所述终端设备在每个频段上的最大带宽能力信息也可以包括SCS粒度的最大带宽能力信息。例如,每个频段上的最大带宽能力信息包括至少一个最大带宽能力信息,所述至少一个最大带宽能力信息中的每个最大带宽能力信息对应一个SCS。可选地,每个SCS对应的最大带宽能力可以相同或者也可以不同。
可选地,在一些实施例中,所述终端设备在所述每个频段上的最大带宽能力信息可以不区分上下行。
在另一些实施例中,所述每个频段上的最大带宽能力信息也可以包括上下行粒度的最大带宽能力信息。例如,每个频段上的最大带宽能力信息包括所述终端设备在所述每个频段上的上行最大带宽能力信息和/或下行最大带宽能力信息。
可选地,所述终端设备在每个频段上的上行最大带宽能力和下行最大带宽能力可以相同或者也可以不同。
可选地,在一些实施例中,所述终端设备在每个频段上的最大带宽能力信息可以包括以SCS以及上下行粒度的最大带宽能力信息。即终端设备在频段上的最大带宽能力信息即区分SCS又区分上下行。
作为一个示例,所述终端设备在每个频段上的最大带宽能力信息可以包括第一上行 最大带宽能力信息组和/或第一下行最大带宽能力信息组,该第一上行最大带宽能力信息组包括至少一个第一上行最大带宽能力信息,该至少一个第一上行最大带宽能力信息为所述终端设备在该每个频段上的上行最大带宽能力,其中,每个第一上行最大带宽能力对应一个SCS,该第一下行最大带宽能力信息组包括至少一个第一下行最大带宽能力信息,该至少一个第一下行最大带宽能力信息为终端设备在该每个频段上的下行最大带宽能力,其中,每个第一下行最大带宽能力对应一个SCS。
因此,在该实施例2-1中,终端设备上报的每个频段上的最大带宽能力可以是不区分SCS和上下行的最大带宽能力,或者可以是以SCS和/或上下行为粒度的,本申请对此不作限定。
以终端设备在Band A、15khz SCS下的带宽支持情况举例说明(其他SCS如30KHz、60KHz等类似)。假设终端设备在该Band A、15khz SCS支持的带宽情况如表3所示。其中,在15KHz SCS下该Band A定义了5~50MHz的信道带宽,在相关技术中,终端设备上报的能力信息仅包括这些带宽。
表3
Figure PCTCN2020141051-appb-000003
假设Band A引入了新的带宽70MHz和90MHz,那么对于新引入的带宽。目前已上市的终端设备是无法使用这两个带宽的,因为其上报的能力信息中不包含这两个新增的70MHz和90MHz带宽。
当引入新的带宽时,目前的处理方式是定义新的带宽能力信息如70MHz_support、90MHz_support,终端设备上报是否支持该带宽。
在本申请实施例中,假设终端设备只需上报其支持的最大带宽能力,例如80MHz,而不需对每个新引入的带宽都进行能力上报,对应地,网络设备可以根据该最大带宽能力确定终端设备支持70MHz,不支持90MHz,即终端设备实际支持的带宽如表4所示:
表4
Figure PCTCN2020141051-appb-000004
进一步地,在进行带宽配置时,网络设备可以将该70MHz配置给终端设备。
因此,基于本申请实施例的上报方式可以实现已有终端前向兼容新引入的带宽(例如,比终端设备的最大带宽能力MaxCBW小的带宽)并支持网络设备对该新增带宽的配置。同时降低了终端设备单独上报各个新引入的带宽是否支持的能力信息的信令开销。
实施例2-2
可选地,在一些实施例中,所述第一信息包括所述终端设备在至少一个频段中的每个频段上能够支持的所有带宽。
应理解,该终端设备在某个频段上能够支持的所有带宽可以包括终端设备的在该频段上的能力所能支持的带宽,该所有带宽可以包括未定义的带宽,例如,在该频段上已定义的最大带宽为100MHz,若终端设备在该频段上的能力可以支持120MHz,则该终端设备在该频段上能够支持的所有带宽可以包括120MHz。
在一些实施例中,所述终端设备在每个频段上能够支持的所有带宽可以是不区分SCS的。在另一些实施例中,所述终端设备在每个频段上能够支持的所有带宽也可以是 以SCS为粒度的。
在一些实施例中,所述终端设备在每个频段上能够支持的所有带宽可以是不区分上下行的。在另一些实施例中,所述终端设备在每个频段上能够支持的所有带宽也可以是区分上下行的。
实施例2-3

可选地,该每个频段对应的所有带宽可以包括预定义的带宽,例如5MHz-50MHz,或者,也可以包括标准中该频段对应的已定义的所有带宽,例如包括表1中的所有带宽,即5MHz~100MHz。
可选地,每个频段对应的所有带宽可以相同,或者也可以不同。例如,均为5~100MHz。
可选地,在一些实施例中,所述终端设备未上报某个频段对应的最大带宽能力信息,可以表示该频段支持的最大带宽能力为默认值,例如,50MHz。
例如,若所述第一信息不包括第一频段对应的最大带宽能力信息,表示所述终端设备在所述第一频段支持的最大带宽能力为特定带宽能力,例如,50MHz。
可选地,在一些实施例中,所述终端设备在第二频段上的最大带宽能力信息包括一组最大带宽能力信息,所述一组最大带宽能力信息对应包括所述第二频段的所有频段组合;或者,所述终端设备在第二频段上的最大带宽能力信息包括多组最大带宽能力信息,每组最大带宽能力信息对应包括所述第二频段的至少一个频段组合。
即终端设备在以频段为粒度进行最大带宽能力上报时,可以上报该频段在包括该频段的频段组合下的最大带宽能力信息。
可选地,在一些实施例中,每组最大带宽能力信息可以包括不同SCS对应的最大带宽能力信息,和/或,上下行分别对应的最大带宽能信息等。
应理解,在本申请实施例中,单个频段对应的最大带宽能力信息与该频段在频段组合下的最大带宽能力信息可以相同,或者也可以不同,本申请对此不作限定。
例如,针对一个频段(如Band A),则终端设备可以上报一个最大带宽能力MaxCBW_A,对应包括Band_A的所有的不同频段组合,例如Band A+Band B、Band A+Band C、Band A+Band D、Band A+Band B+Band C、Band A+Band B+Band D等等;或者,终端设备也可以上报多个最大带宽能力(如MaxCBW_A1、MaxCBW_A2等),对应Band A构成的不同的频段组合,例如MaxCBW_A1对应Band A+Band B、Band A+Band C、Band A+Band D;MaxCBW_A2对应Band A+Band B+Band C、Band A+Band B+Band D等等。

可选地,在一些实施例中,所述终端设备在在所述每个频段组合中的每个频段上的最大带宽能力信息可以包括以SCS以及上下行粒度的最大带宽能力信息。即终端设备在在所述每个频段组合中的每个频段上的最大带宽能力信息即区分SCS又区分上下行。
可选地,在一些实施例中,针对一个频段,所述终端设备可以上报该频段对应的一组最大带宽能力信息,所述一组最大带宽能力信息对应包括所述该频段的所有频段组合;或者所述终端设备上报该频段上对应的多组最大带宽能力信息,每组最大带宽能力信息对应包括所述第二频段的至少一个频段组合。

综上,在该实施例3-1中,终端设备上报的每个频段组合中的每个频段上的最大带宽能力可以是不区分SCS和上下行的最大带宽能力,或者可以是以SCS和/或上下行为粒度的,本申请对此不作限定。
在相关技术中,对于频段组合(Band combination)支持的带宽组合(Bandwidth combination),是通过定新的带宽组合集合(Bandwidth combination set)的方式来实现的。表5示出了频段组合A+B在15KHz SCS下的支持带宽组合的情况下。具体为频段A支持5MHz~50MHz,频段B支持5MHz~20MHz,这个带宽组合集合定义为Bandwidth combination set 0。
表5
Figure PCTCN2020141051-appb-000005
当在频段A和/或频段B引入新的带宽时,按照现有的方式需要定义新的带宽组合集合,例如Bandwidth combination set 1来包含新的带宽。比如频段A新引入70MHz和90MHz,那么需要定义如下Bandwidth combination set 1。对于已上市的终端,按照现有的方式是无法支持这个新增的Bandwidth combination set 1的,因为其上报的带宽能力仅 包含Bandwidth combination set 0。
在本申请实施例中,可以通过上报频段组合中的每个频段的最大带宽能力信息实现对新引入的带宽或带宽组合的前向兼容性,从而能够降低在每新引入一个带宽时都需要上报其支持的带宽组合能力信息的信令开销。
在上面的例子中,假设终端设备在Band A+Band B组合中Band A下能够支持的最大带宽能力假设为80MHz,那么在Band A+Band B组合下,终端设备可以支持新引入的70MHz并与Band B支持的各带宽构成的带宽组合集合,即支持等同于表6中的带宽组合集合1。由于90MHz超过了Band A在Band A+Band B组合下能支持的最大带宽能力80MHz,因此在下述带宽组合集合1中并不包含90MHz。

应理解,上述示例仅以Band A引入新的带宽为例进行介绍,当Band B也有新的带宽引入时,处理方式跟Band A相同。比如Band B引入新的带宽30MHz和50MHz时,而终端设备在Band A+Band B组合中的Band B上支持的最大带宽能力为40MHz,那么该终端设备在Band B上可以支持新引入的30MHz而不支持50MHz。因此终端设备实际支持的带宽组合集合等效为表7所示的带宽组合集合1。

实施例3-2
可选地,在一些实施例中,所述终端设备在所述每个频段组合上的最大带宽能力信息包括:所述终端设备在所述每个频段组合中的每个频段上能够支持的所有带宽。
应理解,该终端设备在某个频段上能够支持的所有带宽可以包括终端设备的在该频段上的能力所能支持的带宽,该所有带宽可以包括未定义的带宽,例如,在该频段上已定义的最大带宽为100MHz,若终端设备在该频段上的能力可以支持120MHz,则该终端设备在该频段上能够支持的所有带宽可以包括120MHz。
在一些实施例中,所述终端设备在所述每个频段组合中的每个频段上能够支持的所有带宽可以是不区分SCS的。在另一些实施例中,所述终端设备在所述每个频段组合中的每个频段上能够支持的所有带宽也可以是以SCS为粒度的。
在一些实施例中,所述终端设备在所述每个频段组合中的每个频段上能够支持的所有带宽可以是不区分上下行的。在另一些实施例中,所述终端设备在所述每个频段组合中的每个频段上能够支持的所有带宽也可以是区分上下行的。
实施例3-3
可选地,在一些实施例中,所述终端设备在所述每个频段组合上的最大带宽能力信息包括所述终端设备在所述每个频段组合中的每个频段上是否能够支持所有带宽的指示信息。
可选地,该每个频段对应的所有带宽可以包括预定义的带宽,例如5MHz-50MHz,或者,也可以包括标准中该频段对应的已定义的所有带宽,例如包括表1中的所有带宽,即5MHz~100MHz。
可选地,每个频段对应的所有带宽可以相同,或者也可以不同。例如,均为5~100MHz。
作为一个示例,所述终端设备通过比特映射(bitmap)方式上报终端设备在每个频段组合中的每个频段上是否支持所有带宽的信息。例如,所述第一信息可以包括第二比特位图,所述第二比特位图包括多个比特位,每个频段组合对应其中的至少两个比特位,所述至少两个比特位中的每个比特位的取值对应该频段组合中的一个频段,每个比特位的取值用于指示对应的频段是否支持所有带宽。
实施例3-4
可选地,在一些实施例中,所述终端设备在所述每个频段组合上的最大带宽能力信息包括所述终端设备在所述每个频段组合中的所有频段上的最大带宽能力之和。
例如,终端设备在Band A+Band B中的Band A下的最大带宽能力为MaxCBW_A,在Band A+Band B中的Band B下的最大带宽能力为MaxCBW_B,在一种实现方式中,终端设备可以上报该MaxCBW_A和MaxCBW_B,在另一种实现方式中,终端设备上报其在Band A+Band B下的总的最大信道能力,即MaxCBW_A+MaxCBW_B,网络设备在进行带宽配置时只要在Band A和Band B下配置的带宽之和小于等于MaxCBW_A+MaxCBW_B即可,采用此上报方式相对于前述实施例中上报每个频段上的最大带宽能力的上报方式更加灵活,并且有利于降低信令开销。
实施例4
可选地,所述第一信息包括在至少一个工作状态下所述终端设备支持的最大带宽能力信息。
应理解,在一些场景中,终端设备支持的最大带宽能力通常与终端设备的工作状态相关,即在不同的工作状态下,终端设备支持的最大带宽能力可能不同。因此,在一些实施例中,终端设备可以上报至少一个工作状态下的最大带宽能力,从而网络设备可以基于终端设备当前的工作状态对终端设备进行合适的配置。
可选地,在一些实施例中,所述工作状态包括多输入多输出(Multiple Input Multiple Output,MIMO)的工作状态,或者,也可以包括其他可能影响终端设备的带宽能力的性能参数,或工作状态参数,本申请对此不作限定。
作为一个示例,对于频段组合Band A+Band B中的Band A,当Band A工作在小于X流MIMO(X小于4,例如1或2等)时,该Band A的最大带宽能力为90MHz,当Band A工作在4流MIMO时,该Band A的最大带宽能力为70MHz。因此,终端设备可以上报该Band A在Band A+Band B下的最大带宽能力包括:70MHz,对应小于4流MIMO的工作状态;90MHz,对应4流MIMO的工作状态。
应理解,该实施例5中的终端设备支持的最大带宽能力可以采用前述实施例1至实施例4中的任意一个或多个实施例实现。
还应理解,前述实施例1至实施例4中的所述第一信息的实现方式可以单独实施,或者也可以结合实施,本申请对此不作限定。
可选地,在一些实施例中,所述终端设备可以向网络设备上报第二信息,所述第二信息用于指示所述终端设备的至少一个工作状态。网络设备在对终端设备进行频段和/或带宽配置时,可以考虑该终端设备的当前的工作状态,从而能够进行合适的配置。
