5G技术期望通过一个网络同时支持多种多样的场景和业务类型。多种多样的场景包括自动驾驶、智慧城市、智能电网、智能工厂等；多种多样的业务包括增强移动宽带(enhanced mobile broadband，eMBB)业务、超高可靠低时延(ultra-high reliability and low latency，URLLC)业务和大规模机器类通信(massive machine-type communication，mMTC)业务等。不同场景和/或不同业务往往对应不同的需求。例如，eMBB业务通常追求的是高吞吐量和高频谱效率，URLLC业务通常追求的是高可靠和低时延，mMTC业务通常追求的是广覆盖和大连接。使用一套参数同时支持这样多种多样的场景和业务类型，并不能达到最优的系统性能。例如，优化高可靠低时延往往是以降低频谱效率为代价的。因此，第三代合作伙伴计划(3rd generation partnership project，3GPP)提出通过网络切片(network slice)的方式来支持5G系统多种多样的场景和业务类型。在无线接入网层面，网络切片是通过空口切片来实现的，核心网被划分成多个网络切片，每个网络切片通过一个空口切片来承载，用来实现终端设备侧一个特定的服务需求。

另外，在本申请实施例中，“示例性的”一词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
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。
参见图3，为本申请实施例提供的一种能力配置方法流程示意图。该方法包括：
步骤301：网络设备向终端设备发送能力配置信息；所述能力配置信息用于指示与所述终端设备支持的空口切片对应的能力。
示例性的，本申请实施例中，所述终端设备支持的空口切片对应的能力为从所述终端设备上报的能力候选集合中确定出的。在该实现方式下，网络设备在发送能力配置信息之前，终端设备可以向网络设备上报终端设备的能力候选集合。
当然，终端设备也可以不需要上报终端设备的能力候选集合，网络设备与终端设备之间可以对能力候选集合进行预先约定，此时终端设备支持的空口切片对应的能力为从预先约定的能力候选集合中确定出的。
需要说明的是，空口切片可以用来承载网络切片，对应一种特定业务的传输块(transmission block，TB)承载在特定的空口切片上。空口切片可以是指不同的服务小区，或者不同的载波，或者不同的带宽部分(bandwidth part，BWP)，也可以是指不同的层，或者不同的天线端口。
应理解，服务小区是高层从资源管理或移动性管理或服务单元的角度来描述的。每个网络设备的覆盖范围可以被划分为一个或多个服务小区，且该服务小区可以看作由一定频域资源组成，即一个服务小区可以包括一个或多个载波。载波的概念是从物理层的信号产生的角度来描述的。一个载波由一个或多个频点定义，对应一段连续或非连续的频谱，用于承载网络设备和终端间的通信数据。下行载波可以用于下行传输，上行载波可以用于上行传输。
应理解，BWP也可以称为带宽、载波带宽部分(carrier bandwidth part)、子带(subband)带宽、窄带(narrowband)带宽、或者其他名称，本申请对名称并不做限定，且下述实施例对不同名称不进行区分。可以在一个上行载波上配置多个上行带宽部分，可以在一个下行载波上配置多个下行带宽部分。或者，本申请实施例涉及到的多个带宽部分可以位于同一小区内或同一载波上，也可以位于不同小区内或不同载波上。
示例性的，一个BWP可以包含连续的K(K>0)个子载波；或者，一个BWP为N个不重叠的连续的资源块(resource block，RB)所在的频域资源，该RB的子载波间隔可以为15KHz、30KHz、60KHz、120KHz、240KHz、480KHz或其他值。或者，一个BWP为M个不重叠的连续的资源块组(resource block group，RBG)所在的频域资源，一个RBG 包括P个连续的RB，该RB的子载波间隔可以为15KHz、30KHz、60KHz、120KHz、240KHz、480KHz或其他值，例如为2的整数倍。
应理解，一个TB经过信道编码处理后就称为一个码字。由于码字数量与发送天线数量不同，需要将码字映射到不同的天线上，因此引入了层的概念。层数等于信道矩阵的秩，即能够独立并行传输的数据流数量。天线端口的概念是从接收端的角度来定义的(下行的接收是终端设备，上行的接收是网络设备)，一个端口对于接收端来说就是一个独立的天线信道。
步骤302：终端设备从网络设备接收能力配置信息。
步骤303：所述网络设备通过所述终端设备支持的空口切片与所述终端设备进行通信。
步骤304：所述终端设备在所述终端设备支持的空口切片上，使用所述能力配置信息指示的能力与所述网络设备进行通信。
通过上述方法，网络设备通过能力配置信息，为终端设备配置与其支持的空口切片相匹配的能力，可以保证网络设备和终端设备对于终端设备支持的空口切片上的能力有共同的认知，从而解决在终端设备支持多个空口切片的情况下，网络设备如何确定终端设备在每个空口切片中的能力的问题。
本申请实施例中，能力候选集合中的能力包括但不限于以下一项或多项：
终端设备进行通信时可以使用的射频通道的数量；
并行处理的TB数量；
并行处理的码块(code block，CB)数量；
终端设备解调TB时所使用的快速傅里叶变换(fast Fourier transfer，FFT)的数量；
终端设备解调CB时所使用的FFT的数量；
终端设备支持的下行控制信息(downlink control information，DCI)的数量；
最大控制信道盲检次数；
最大控制信道估计次数；
终端设备支持的最大混合自动重传请求(hybrid automatic repeat request，HARQ)实体数量；
终端设备需要反馈的CQI的数量。
当然，以上只是示例，能力候选集合中还可能存在其他能力，在此不再逐一举例说明。
本申请实施例中，终端设备的能力可以包括两种类型：独有能力和共享能力。其中，独有能力可以为随终端设备支持的空口切片数量增加而增加的能力，独有能力约束于在各空口切片上的能力约束和总能力约束，或者，从另一个角度来说，独有能力为仅覆盖一个空口切片的能力。相应的，共享能力可以为不随终端设备支持的空口切片数量增加而增加的能力，共享能力在不同空口切片上进行分配，或者，从另一个角度来说，共享能力为可以覆盖多个(至少2个)空口切片的能力。
结合上面的描述，本申请实施例中，能力候选集合中包括至少一个独有能力，或者包括至少一个共享能力，或者包括至少一个独有能力以及至少一个共享能力。
本申请实施例中，网络设备可以配置终端设备在给定多切片实现方式下哪些能力为共享能力，哪些能力为独有能力。示例性的，终端设备在通过多个载波或多个载波带宽部分(carrier bandwidth part，BWP)实现支持多个空口切片的场景下，可以将一个TB映射在所述多个空口切片上，其中一个TB可以划分为多个CB。此时，可以将终端设备同时传输 的TB数作为一个共享能力与多个空口切片相匹配。相应的，网络设备可以配置将该TB中包括的CB分别映射在所述多个空口切片上。通过这种配置，将一个TB映射在多个空口切片上，可以减少控制信令的开销，也有利于提高该TB的传输分集增益，进而提高其传输鲁棒性。
示例性的，终端设备在通过多个载波或多个载波BWP实现支持多个空口切片的场景下，还可以将多个空口切片上的信息通过一个FFT调制成一个较长的正交频分复用(orthogonal frequency division multiplexing，OFDM)基带信号。此时，可以将终端设备的FFT个数作为一个共享能力与多个空口切片相匹配。相应的，网络设备可以配置该在所述多个空口切片上的FFT点数，对应所述多个空口切片上分配的频域资源(例如子载波)数。通过这种配置，将多个空口切片上的信息通过一个FFT调制成一个较长的OFDM基带信号，可以降低信号峰值平均功率比(peak to average power radio，PAPR)，减少频谱扩展干扰以及带内信号畸变，也可以提高变换后时域信号的分辨率，有利于对噪声干扰的抑制，从而获得更好的传输质量。
示例性的，终端设备通过同频带连续(intra-band contiguous)载波聚合(carrier aggregation，CA)方式支持多个空口切片时，网络设备可以将终端设备使用的射频通道数量作为一个共享能力与多个空口切片相匹配，此时，可以配置终端设备使用1个射频通道。通过这种配置，可以简化终端设备的射频结构(例如只使用一个功率放大器)，当终端设备在至少2个载波上的激活BWP都比较大时，更有利于终端设备节能。需要说明的是，在该场景下，网络设备也可以根据实际情况配置终端设备使用的射频通道数量。举例来说，当终端设备需要在各载波上做进一步节能，即将终端设备的工作带宽回退至默认(default)BWP上时，网络设备可以配置终端设备使用2个射频通道。
再举例来说，终端设备在通过多个BWP实现支持多个空口切片的场景下，网络设备可以配置终端设备使用至少2个射频通道，这样可以避免控制信道和数据信道子载波间隔不同时引入的射频切换时延，提高终端设备吞吐量。相反，在该场景下，当终端设备只使用1个射频通道时，这种切换时延会造成控制信道结束位置和数据信道开始位置之间的多个符号不能被使用，从而影响终端设备吞吐量。
本申请实施例中，网络设备通过能力配置信息指示的能力，为与终端设备支持的空口切片相匹配的能力。与终端设备支持的空口切片相匹配的能力，可以是指能够满足空口切片的需求的能力。
举例来说，终端设备的能力候选集合中包括第一独有能力，所述第一独有能力为所述终端设备在第一射频通道上对应的物理上行共享信道(physical uplink shared channel，PUSCH)准备时长T1和上行BWP切换时长T2；所述终端设备支持的空口切片所需的PUSCH定时时长为T3；当所述T3大于或等于所述T1与所述T2之间的最大值时，所述能力配置信息指示的能力中包括所述第一独有能力。相应的，当所述T3小于所述T1与所述T2之间的最大值时，所述能力配置信息指示的能力中不包括所述第一独有能力。其中，PUSCH定时时长力可以是指，承载调度PUSCH的DCI的物理下行控制信道(physical downlink control channel，PDCCH)的最后一个符号到PUSCH的循环前缀(cyclic prefix，CP)的起始符号之间的定时时长，PUSCH定时时长等于PUSCH准备时长与上行BWP切换时长之间的最大值；PUSCH准备时长可以是指，终端设备将需要传输的信息，映射到PUSCH上所需的时长；上行BWP切换时长可以是指，终端设备在两个上行BWP之间切 换所需的时长。时长的单位可以为OFDM符号，也可以为秒或分钟等，本申请实施例对此并不限定。例如，终端设备在射频通道1上的PUSCH准备时长为5个OFDM符号，上行BWP切换时长为10个OFDM符号；终端设备在射频通道2上的PUSCH准备时长为10个OFDM符号，上行BWP切换时长为15个OFDM符号；终端设备支持的空口切片需求的PUSCH定时时长为12个OFDM符号。由于终端设备在射频通道1中，PUSCH准备时长和上行BWP切换时长之间的最大值为10个OFDM符号，满足终端设备支持的空口切片需求的12个OFDM符号的PUSCH定时时长；而终端设备在射频通道2中，PUSCH准备时长和上行BWP切换时长之间的最大值为15个OFDM符号，不满足终端设备支持的空口切片需求的12个OFDM符号的PUSCH定时时长。因此网络设备可以通过能力配置信息指示终端设备在空口切片中使用射频通道1进行收发。
再举例来说，终端设备的能力候选集合中包括第一共享能力，所述第一共享能力为最大控制信道盲检能力，用于指示所述终端设备的最大控制信道盲检次数B1；所述能力指示信息指示的能力中包括所述终端设备在至少两个空口切片中的最大控制信道盲检次数B2，其中B2小于或等于B1。其中，终端设备在一个空口切片中的最大控制信道盲检次数，可以是指，终端设备在该空口切片的BWP中的搜索空间集合，所对应的盲检次数。例如，终端设备支持空口切片1和空口切片2，空口切片1中配置了BWP1，空口切片2中配置了BWP2。在BWP1中配置了搜索空间集合0，对应最大控制信道盲检次数为15，和搜索空间集合1，对应最大控制信道盲检次数为20；在BWP2中配置了搜索空间集合2，对应最大控制信道盲检次数为10，和搜索空间集合3，对应最大控制信道盲检次数为15。假设终端设备的最大控制信道盲检次数为44次，并在搜索空间集合0～3中分配。如果按现有技术中的方法，终端设备响应依次判断搜索空间集合0～3是否可以被盲检，最终确定搜索空间集合0和搜索空间集合1，对应的最大控制信道盲检次数之和为35，因此终端设备只盲检搜索空间集合0和1。本申请实施例中，网络设备可以配置终端设备在BWP1中最大盲检次数为20次，在BWP2中最大盲检次数为20次。此时，终端设备在进行盲检时，由于在BWP1中最大盲检次数为20次，因此只盲检搜索空间集合0，不再盲检搜索空间集合1；同样的，由于在BWP2中最大盲检次数为20次，因此只盲检搜索空间集合2，不再盲检搜索空间集合3。
通过上面的方法，使得终端设备的能力与终端设备支持的空口切片上的需求相匹配，从而能够保证终端设备和网络设备对于给定空口切片上的能力有共同的认知。
进一步，可选的，本申请实施例中，终端设备的一个能力在不同场景下，可以配置为独有能力，也可以配置为共享能力，即对于不同的配置，共享能力和独有能力之间可以互相转换。
举例来说，当所述终端设备通过同频带连续载波聚合方式支持至少两个空口切片时，网络设备可以配置以下一项或多项共享能力：
使用的射频通道的数量；终端设备解调TB时所使用的FFT的数量；终端设备解调CB时所使用的FFT的数量。
相应的，在该场景下，网络设备可以配置以下一项或多项独有能力：
并行处理的TB数量；并行处理的CB数量；支持的DCI的数量；最大控制信道盲检次数；最大控制信道估计次数；终端设备支持的最大HARQ实体数量；终端设备需要反馈的CQI的数量。
例如，如图4所示，终端设备在带宽A中以载波聚合方式占用两个成员载波(component carrier，CC)：CC1和CC2，终端设备还通过同频带连续载波聚合方式支持2个空口切片，每个空口切片对应一个成员载波。在该情况下，终端设备的共享能力可以包括以下至少一项：终端设备可以使用1个射频通道进行收发；
若两个成员载波上传输数据使用的子载波间隔相同，则终端设备可以使用1个FFT解调2个TB；
若两个成员载波上传输数据使用的子载波间隔相同，则终端设备可以使用1个FFT解调2个CB。
相应的，终端设备的独有能力可以包括以下至少一项：
终端设备需要支持的DCI数量为2个；
以2个成员载波对应的控制信道均为15kHz为例，终端设备需要进行的最大控制信道盲检次数为2*44＝88次；
终端设备需要进行的最大控制信道估计次数为2*56＝112次；
终端设备需要并行处理2个TB；
终端设备需要并行处理2个CB；
终端设备的最大HARQ实体为2个；
终端设备需要反馈的CQI数为2个。
而当所述终端设备通过多输入多输出(multiple input multiple output，MIMO)方式支持至少两个空口切片时，网络设备可以配置以下一项或多项共享能力：
使用的射频通道的数量；支持的DCI的数量；最大控制信道盲检次数；最大控制信道估计次数；终端设备支持的最大HARQ实体数量。
相应的，在该场景下，网络设备可以配置以下一项或多项独有能力：
并行处理的TB数量；并行处理的CB数量；解调传输块TB所使用的FFT的数量；解调CB所使用的FFT的数量；反馈CQI的数量。
例如，如图5所示，终端设备通过4x2(即4个发射天线x2个接收天线)MIMO方式支持两个空口切片时，终端设备的共享能力可以包括以下至少一项：
终端设备可以使用1个射频通道进行收发；
终端设备需要支持的DCI数量为1个；
以终端设备所在的成员载波对应的控制信道均为15kHz为例，终端设备需要进行的最大控制信道盲检次数为44次；
终端设备需要进行的最大控制信道估计次数为56次；
终端设备的最大HARQ实体为1个。
相应的，终端设备的独有能力可以包括以下至少一项：
终端设备需要使用2个FFT解调2个TB；
终端设备需要使用2个FFT解调2个CB；
终端设备需要并行处理2个TB；
终端设备需要并行处理2个CB；
终端设备需要反馈的CQI数为2个。
而当所述终端设备通过重叠的BWP方式支持至少两个空口切片时，网络设备可以配置以下一项或多项共享能力：
使用的射频通道的数量；最大控制信道盲检次数；最大控制信道估计次数；最大HARQ实体数量；反馈CQI的数量。
相应的，在该场景下，网络设备可以配置以下一项或多项独有能力：支持的DCI的数量；并行处理的TB数量；并行处理的CB数量；解调TB所使用的FFT的数量；解调CB所使用的FFT的数量。
例如，如图6所示，终端设备通过两个重叠的BWP支持两个空口切片，其中，两个重叠的BWP中的BWP1的子载波间隔为60kHz，两个重叠的BWP中的BWP2的子载波间隔为30kHz；BWP2上的数据信道通过BWP1上的控制信道跨BWP调度。在该场景下，终端设备的共享能力可以包括以下至少一项：
终端设备可以使用1个射频通道进行收发；
终端设备需要进行的最大控制信道盲检次数为44次；
终端设备需要进行的最大控制信道估计次数为56次；
终端设备的最大HARQ实体为1个；
终端设备需要反馈的CQI数为2个。
相应的，终端设备的独有能力可以包括以下至少一项：
终端设备需要支持的DCI数量为2个；
终端设备需要使用2个FFT解调2个TB；
终端设备需要使用2个FFT解调2个CB；
终端设备需要并行处理2个TB；
终端设备需要并行处理2个CB。
从上述举例可以看出，终端设备的能力，在不同场景下，可以配置为独有能力，也可以配置为共享能力。当然以上只是示例，还可能存在其他能力配置，在此不再逐一举例说明。

本申请实施例中所描述的方法或算法的步骤可以直接嵌入硬件、处理器执行的软件单元、或者这两者的结合。软件单元可以存储于RAM存储器、闪存、ROM存储器、EPROM存储器、EEPROM存储器、寄存器、硬盘、可移动磁盘、CD-ROM或本领域中其它任意形式的存储媒介中。示例性地，存储媒介可以与处理器连接，以使得处理器可以从存储媒介中读取信息，并可以向存储媒介存写信息。可选地，存储媒介还可以集成到处理器中。处理器和存储媒介可以设置于ASIC中，ASIC可以设置于终端设备中。可选地，处理器和存储媒介也可以设置于终端设备中的不同的部件中。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上，使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理，从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
显然，本领域的技术人员可以对本申请进行各种改动和变型而不脱离本申请的范围。这样，倘若本申请的这些修改和变型属于本申请权利要求及其等同技术的范围之内，则本 申请也意图包含这些改动和变型在内。
