背景技术
随着5G终端的发展和演进，单一网络业务设计已不能再满足5G多业务多场景的需求，基于不同业务及场景需求，将端到端的网络资源等进行差异化的不同的定制、分配及调度，我们将此称之为切片。5G网切片技术可分为5G组网架构切片、核心网切片、传输网切片、无线网切片几个部分。根据切片的不同，即可满足不同的业务场景对吞吐、带宽、时延及可靠性网络通讯质量需求。针对用户差异化的需求，基站系统侧已经有了相应的差异化切片策略设计，根据当前5G的三大应用场景，如应用于大带宽、大数据量业务的面向增强型移动宽带网络切片方案，应用于毫秒级低时延通讯网络切片方案，应用于物联网领域的高网络密度及覆盖网络切片方案。
目前网络切片方案仅在于核心网侧，其次是无线接入网层和传输网层，导致终端侧无法根据不同的业务场景和用户需求进行终端资源的合理化调度。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施例中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
针对用户差异化的需求，基站系统侧已经有了相应的差异化切片策略设计，根据当前5G的三大应用场景，如应用于大带宽、大数据量业务的面向增强型移动宽带网络切片方案，应用于毫秒级低时延通讯网络切片方案，应用于物联网领域的高网络密度及覆盖网络切片方案。而对于5G终端侧的用户来说，如果终端用户涉及到高速上传下载，高清视频及语音，多人在线游戏，多人在线直播，高清等，所需的吞吐就会很大，此时需要切片处理到高速吞吐模式；如果终端用户只是做微信聊天，网页浏览，小文件传输，所需的吞吐相应会很小，此时只需要切片处理到低速吞吐模式。传统的网络切片仅在于核心网侧，其次是无线接入网层，和传输网层，而在终端这一侧没有提及。如果终端上没有做切片处理，而系统分配或当前工作的吞吐和通道冗余，就会造成流量，功耗的浪费；如果分配的吞吐和通道不足，或信道堵塞，误码严重，就会造成实际使用的卡顿和不顺。
本申请的一个实施例涉及一种业务切片的调整方法，应用在终端侧，如图1所示，包括：
步骤101，获取为终端配置的应用业务切片的业务需求参数和终端的当前网络参数，其中，业务需求参数包含应用业务切片的各子切片的业务需求参数。
在一示例性实施中，终端的应用业务切片简单划分为数据业务切片和通话业务切片，具体到应用有高速下载上传、高清视频、高清视频通话、高流量游戏、云业务、增强现实和虚拟现实等高速吞吐应用业务切片；网络聊天业务、网页浏览、单人小游戏、手机支付、手机阅读和低速传输等低速吞吐应用业务切片。因业务性质的不同，上述不同的业务所需要的网络类型、上传和下载流量需求、时延、同时接入终端数量等都不同。而对于同一个应用业务切片(如：游戏业务切片)来讲，也会有不同的实时需求，比单人在线游戏业务切片、多人在线网络游戏业务切片、低分辨率游戏业务切片、高分辨率游戏业务切片、2D游戏业务切片、3D游戏业务切片等；由于不同游戏业务切片的画面、分辨率、剧情、地图，是否3D等不同，游戏业务切片所需要的切片参数就不相同。
在一示例性实施中，业务需求参数可以包括吞吐量、吞吐速率、频谱范围(即工作频点)、频谱带宽、干扰参数、和上行功率参数等信息，获取为终端配置的应用业务切片的业务需求 参数可以包括下述4种方法。
第一种：当检测终端打开的应用业务切片时，采集终端的射频信息参数集，对射频信息参数集进行统计分析，获取应用业务切片的业务需求参数。
第二种：当检测终端打开的应用业务切片时，获取打开应用业务切片时和运行应用业务切片时的时延，获取打开应用业务切片的速度，根据时延、速度和预设的目标阈值获取应用业务切片的业务需求参数。
第三种：基站核心网，承载网、传输网的切片网络信息通过特定消息下发给终端，终端接收到影响的切片网络信息后，将基站所传输的切片网络信息作为终端的应用业务切片的业务需求参数。
第四种：用户UI界面设置的业务需求信息，指的是终端用户专门的切片需求申请及设置，此设置通过在终端UI界面的设置菜单来设置，通过已定义的切换窗口及选项，用户可以设置终端侧的切片需求举例如下：最大上行吞吐，最大下行吞吐，业务匹配网速吞吐，最低时延吞吐，最低功耗吞吐，增强信号吞吐，游戏模式吞吐，高清视频模式吞吐，降温模式吞吐，红包切片模式吞吐等信息。
在一示例性实施中，可以将第一种和第二种方法结合起来使用，为第一种方法和第二种方法所采集的参数设置不同的加权参数之后，通过加权的方法获取到业务需求参数。
在一示例性实施中，当前网络参数可以包括吞吐量、网速、吞吐速率、频谱范围(即工作频点)、频谱带宽、干扰参数和上行功率参数等，当前网络参数是通过分析终端当前的射频信息参数集获取的。
步骤102，根据业务需求参数、当前网络参数对应用业务切片的各子切片参数进行调整。
在一示例性实施中，应用业务切片的各子切片参数可以包含吞吐子切片参数、功率子切片参数、带宽子切片参数、频谱子切片参数、干扰子切片参数、资源块(Resource Block，简称RB)子切片参数等；当检测到业务需求参数和当前网络参数之间存在差异(即业务需求参数和当前网络参数不相同，或者差值大于预设阈值)时，将各子切片参数调整至与业务需求参数对应的参数值。
本申请提出的业务切片的调整方法，在终端侧进行资源调度的过程中，获取为终端配置的应用业务切片的业务需求参数和所述终端的当前网络参数，其中，所述业务需求参数包含所述应用业务切片的各子切片的业务需求参数；根据所述业务需求参数、所述当前网络参数对所述应用业务切片的各子切片参数进行调整。通过各应用业务切片的业务需求参数和当前网络参数，为各应用业务切片的切片参数进行调整，使得终端能够根据各应用业务切片的业务场景和用户需求进行资源调度，防止终端配置不合适造成的应用业务切片峰值不达标的问题，均衡需求和终端网络资源，起到节电和降热的作用，提高了调度终端资源的合理性和终端资源的利用率，解决了现有技术中由于网络切片方案仅在于核心网侧，导致终端侧无法根据不同的业务场景和用户需求进行终端资源的合理化调度的问题。
本申请的一个实施例涉及一种业务切片的调整方法，如图2所示，包括：
步骤201，获取为终端配置的应用业务切片的业务需求参数和终端的当前网络参数，其中，业务需求参数包含应用业务切片的各子切片的业务需求参数。
在一示例性实施中，本步骤与本申请实施例的步骤101大致相同，此处不一一赘述。
步骤202，根据业务需求参数从预设的切片调整模式中选取与应用业务切片对应的切片 调整模式，其中，切片调整模式用于指示应用业务切片的各子切片参数的调整顺序。
在一示例性实施中，由于5G终端的应用业务切片的调整涉及到各应用业务切片的各子切片参数(如吞吐子切片、功率子切片、频谱子切片、天线子切片等)，在进行应用业务切片的各子切片参数之前，需要决定应用业务切片的各子切片参数的调整顺序，可以根据该模块根据当前的业务需求，连接基站信息(可选的，用于指示应用业务切片的各子切片参数的调整方式)，自身无线参数条件(可选的，即当前网络参数)和内部参数模型(存储预设的切片调整模式，和不同应用业务切片配置下的峰值上行和下行吞吐的储存，不同应用软件历次达到的峰值及均值上下行速率储存等信息)进行计算，匹配最合适的应用业务切片对应的切片调整模式。
此处需要注意的是，本申请还可以存储终端侧各5G切片(即应用业务切片)模型参数，测试参数和控制参数的存储；包括不同带宽、功率、频谱、干扰、RB资源块、长期演进(Long Term Evolution，简称LTE)和新空口(New Radio，简称NR)、载波聚合(Carrier Aggregation，简称CA)模式、上行信道估计(Sounding Reference Signal，简称SRS)模式、多进多出(multiple-in multipleout，简称MIMO)模式、上下天线切换模式下的切片参数存储；同时也用于控制各切片调节参数及驱动代码的存储；还存储不同切片配置下的峰值上行和下行吞吐、不同应用软件历次达到的峰值及均值上下行速率储存，通过大量的使用数据，实时刷新存储应用软件所需的吞吐值。
步骤203，根据业务需求参数、当前网络参数和应用业务切片对应的切片调整模式对应用业务切片的各子切片参数进行调整。
在一示例性实施中，本步骤在本申请实施例的步骤102的调整方法大致相同，区别仅在于增加了各子切片参数的调整顺序，此处不一一赘述。
本申请的实施方式，在其他实施例的基础之上还可以根据应用业务切片的当前需求获取到应用业务切片中各子切片参数的调整顺序，根据优先级对各子切片参数进行调整，提高对应用业务切片进行调整的效率。
本申请的一个实施例涉及一种业务切片的调整方法，如图3所示，包括：
步骤301，获取为终端配置的应用业务切片的业务需求参数和终端的当前网络参数，其中，业务需求参数包含应用业务切片的各子切片的业务需求参数。
在一示例性实施中，本步骤与本申请实施例的步骤101大致相同，此处不一一赘述。
步骤302，根据业务需求参数和当前网络参数获取参数变化值，并根据参数变化值获取调整步进和调整方式。
在一示例性实施中，根据当前的网络参数和业务需求参数，对比改变前后的参数变化值，选择各子切片参数的一种或两种调整方式，并根据参数变化值的大小选择调整步进。
在一示例性实施中，调整方式包括：硬切片电路调整方式、软切片程序调整方式和软硬结合调整三种方式。
在一示例性实施中，硬切片电路调整方式包括：硬切片电路不需要修改射频驱动代码，通过内置于终端内的逻辑门器件，开关完成，逻辑门及开关器件的输入为常规的通用输入与输出口(General-purpose input/output，简称GPIO),输入信号为基站切片指示信号或切片模式映射算法单元输出的切片指示信号，硬切片电路的实现如下，通过多路开关检测不同的网络及业务阈值切片需求，控制当前的终端MIMO模式，SRS模式、功率大小，灵敏度大小。 以NR硬切片的SRS方式为例，通过多路开关检测不同的网络及业务阈值切片需求，控制电路开关逻辑，将当前的终端SRS模式强制打到PMI、1T2R、2T4R、1T4R等几种模式；硬切片电路如图3a所示。
在一示例性实施中，软切片程序调整方式包括：基于软切片程序的参数控制及调整，软切片调整包括网络制式切片、终端NR工作带宽切片、CA组合切片、SRS工作模式切片、MIMO工作模式切片、调度参数切片。终端内部，有正常默认的射频通道驱动代码，用于控制手机按照默认参数进行工作。而这中RFC配置往往没有针对性，是大而全的配置不能满足对应的业务场景需求。软切片控制单元通过调用不同的射频驱动代码，配置不同的切片配置，即通过射频驱动程序控制不同业务和需求下的网络通道、工作模式配置。如图3b所示，以网络制式切片分，将RFC配置为RFC_LTEonly、RFC_SA、RFC_NSA以切片带宽分，将RFC代码分成RFC_WB1、RFC_WB2、RF3_WB3、.....RFC_WBn几种模式。以不同CA组合方式为基础的切片划分，将射频驱动代码(Request For Comments，简称RFC)代码分成RFC_CA1、RFC_CA2、RF3_CA3、.....RFC_CAn几种模式。以不同的SRS工作模式为基础的切片划分，将RFC代码分成RFC_SRS_PMI、RFC_SRS_1T2R、RF3_SRS_1T4R、RFC_SRS_2T4R几种模式。以不同的MIMO工作模式为基础的切片划分，将RFC代码分成RFC_DL_SISO、RFC_DL_22mimo、RFC_DL_33mimo、RFC_DL_44mimo、RFC_UL_SISO、RFC_UL_MIMO几种模式。以不同的调度参数工作模式为基础的切片划分，如当前不同调度限制参数MOD1、MOD2、MOD3、MODn将RFC代码分成RFC_MOD1、RFC_MOD2、RFC_MOD3、RFC_MODn几种模式。
在一示例性实施中，调整步进可以包括小颗粒度的调整、中颗粒度调整和大颗粒度调整或其他任意合适颗粒度的调整步进。例如：通过对比当前网络吞吐信息和目标吞吐的差异，选取对应的颗粒度调整方式，以满足不同用户和业务差异化网络需求。如果当前的上下行吞吐量增加需求量小，终端可直接从LTE模式切换到LTE CA模式，或LTE MIMO模式。如当前的上下行吞吐量增加需求量中等，终端可直接从LTE模式切换到SA模式或NSA模式，如当前的上下行吞吐量增加需求量大，则终端可从当前的LTE模式切换到NR CA模式，或NR CA加LTE CA模式，颗粒尺度依次增加。不同颗粒度映射不同吞吐调整阈值和步进，该调整通过闭环方式优化实现，直到满足业务特征需求。
步骤303，根据调整步进、调整方式、业务需求参数和当前网络参数对应用业务切片的各子切片参数进行调整。
在一示例性实施中，本步骤在本申请实施例的步骤102的调整方法大致相同，区别仅在于设置了各子切片参数的调整方式和调整步进，此处不一一赘述。
本申请的实施方式，在其他实施例的基础之上还可以根据应用业务切片的业务需求和当前网络参数选择合适的调整步进和调整方式，提高对应用业务切片进行调整的效率。
本申请的一个实施例涉及一种业务切片的调整方法，应用在终端侧，如图4所示，包括：
步骤401，获取为终端配置的应用业务切片的业务需求参数和终端的当前网络参数，其中，业务需求参数包含应用业务切片的各子切片的业务需求参数。
在一示例性实施中，本步骤与本申请实施例的步骤101大致相同，此处不一一赘述。
步骤402，根据业务需求参数、当前网络参数对应用业务切片的功率子切片参数进行调整。
在一示例性实施中，当子切片为功率子切片时，业务需求参数为目标上行功率参数，当前网络参数为当前上行功率参数；当目标上行功率参数和当前上行功率参数存在差异时，根据目标上行功率参数调整功率子切片的上行功率参数。而上行功率参数包含三种调整方法：最大功率限值调整方法，增强上行功率调整方法，共享功率调整方法。
在一示例性实施中，最大功率限值调整方法包括：根据目标上行功率参数和业务场景调用相对应的最大发射功率限制；如：NR上行最大发射功率限值是既定的，NSA和SA的上行功率限值也可能不同。如NSA模式下，功率等级3，NR的默认功率23dBm,最大功率一般低于24.5dBm；如SA模式下，功率等级2默认功率25dB,最大功率一般低于26.5dB。而如果当前手机的上行信号比较弱，用户的业务需要提升上行功率来改善上行信号质量及吞吐，此时即需要通过NR功率切片控制，提升NR的上行功率限值。对于A业务场景，调用PowerA最大发射功率限值，对于B业务场景，调用PowerB最大发射功率限值，而一般情况下，调用PowerC默认的最大功率限值。
在一示例性实施中，增强上行功率调整方法包括：功率子切片的上行功率参数包括主天线功率参数和备天线功率参数；先根据目标上行功率参数调整功率子切片的主天线功率参数；当主天线功率参数满足预设的功率限值时，根据目标上行功率参数调整功率子切片的备天线功率参数；调整备天线功率参数可以通过某些无源器件路径以减少整体插损而提升系统功率、可以通过修改功率等级的切片方式，将常规功率等级PC3修改为PC2的高功率模式、或者通过修改校准最大目标功率的切片方式，调用特定高功率的校准切片参数，以提升目标最大功率输出；除此之外，还可以通过主备天线补偿的方式进行，让备天线可以根据需要做一定功率的补偿，如NR主天线功率为25dB,默认备天线功率为22dB，则根据当前上行业务及网络情况特定需求，可将上行功率参数做0-4dB补偿，分别得到22、23、24、25、26的上天线切片功率。
在一示例性实施中，共享功率调整方法包括：当功率子切片为共享功率切片时，上行功率参数包括新空口NR功率参数(5G)和长期演进LTE锚点功率参数(4G)；根据目标上行功率参数调整功率子切片中NR功率参数和LTE锚点功率参数的大小和占比。如：当LTE和NR同时工作时，如果设置了共享功率控制，当NR工作在最大发射功率时，LTE容许回退到一定的功率，同理，当LTE工作在最大功率时，NR也容许回退到一定的功率。这里将LTE或NR回退的功率值做切片处理，如分别回退2dB、4dB、6dB、8dB、10dB、12dB,根据当前的业务需求和网络情况来调整NR功率及LTE锚点功率。
步骤403，根据业务需求参数、当前网络参数对应用业务切片的频谱子切片参数进行调整。
在一示例性实施中，当子切片为频谱子切片时，业务需求参数为目标工作频点和目标吞吐量，当前网络参数为当前工作频点和当前吞吐量；当目标工作频点和当前工作频点存在差异时，根据目标工作频点调整频谱子切片的工作频点。当目标吞吐量和当前吞吐量存在差异时，从预设的吞吐量和频谱带宽的对应关系获取与目标吞吐量对应的目标频谱带宽，根据目标频谱带宽调整频谱子切片的频谱带宽。
在一示例性实施中，对于频谱子切片的工作频点的调整举例如下：如N78有3300-3800MHz频谱范围，将N78分成A段(3300-3500MHz),B段(3500-3700MHz),C段(3700-3800MHz)三段，分别分配给不同的用户及业务，这里的分段可以通过可变滤波器的 方式来实现特定频谱范围的切片控制，而在检测到目标工作频点和当前工作频点存在差异时，如当前工作频点为3400MHz，而目标工作频点为3600MHz，此时当前工作频点和目标工作频点存在200MHz的差距，应该在原有的基础上将该应用业务切片的频谱子切片的工作频点划分到与目标工作频点对应的频谱段中，并将应用业务切片的频谱子切片的工作频点调整为目标工作频点。
在一示例性实施中，对于频谱子切片的频谱带宽的调整举例如下：如N78有10M、20M、40M、50M、60M、80M、90M、100M多种带宽值，不同的业务需求和网络情况对应不同的带宽，将当前的业务吞吐量分成对应的区间等级范围，如100Mbps、200Mbps、400Mbps、500Mbps、600Mbps、800Mbps、900Mbps、1000Mbps及以上。在业务吞吐量为100Mbps时对应的频谱带宽为10M，业务吞吐量为200Mbps时对应的频谱带宽为20M，依次类推；而当目标吞吐量为300Mbps，当前吞吐量为100Mbps时，说明频谱子切片当前吞吐量和目标吞吐量存在一定的差距，若使用当前吞吐量对应的频谱带宽10M在目标吞吐量下工作，会导致业务的延迟和堵塞，需要将频谱子切片的频谱带宽调整至目标吞吐量对应的频谱带宽30M，才能够保证业务的正常传输及运行。同时，不同的带宽通过不同代码来限制调用，即小吞吐业务调用小带宽，大吞吐业务调用大带宽。还由于不同上行质量要求调用不同的NR频谱带宽。如有对上行通讯质量有要求，如还可以误差向量幅度(Error Vector Magnitude，简称EVM)等值进行调整，则需调用对于EVM阈值范围内的NR带宽值，以N1频段为例，如要EVM要求小于1.5％，则只能调动N1 20M以下带宽，如EVM要求小于2％，则可调用N1 30M以下带宽，如EVM要求小于3％，则可调用N1 40M以下带宽。
在一示例性实施中，当频谱子切片为共享频谱切片时，频谱子切片的工作频点包括新空口NR工作频点(5G)和长期演进LTE工作频点(4G)，频谱子切片的频谱带宽包括新空口NR频谱带宽(5G)和长期演进LTE频谱带宽(4G)；根据目标工作频点调整频谱子切片中NR工作频点和LTE工作频点的大小和占比；根据目标频谱带宽调整频谱子切片中NR频谱带宽和LTE频谱带宽的大小和占比。如：NR和LTE在FDD同频段工作时，如N1、N3、N5、N7、N8和LTE B1、B3、B5、B7、B8，可以使用共享频谱的调试来增强吞吐，如N1借用LTE B1的频谱，而由于N1的带宽更灵活，如30MHz、40MHz、50MHz；所以通过如此共享可以增加相应频谱下的吞吐率。不同的是，传统的共享频谱是不能切片处理的，即是统一的频谱共享模式，而这里可以频谱子切片调整频谱共享的范围、区间、带宽；通过检测共享频谱的LTE及NR的信号质量、吞吐需求、或互扰情况，进行动态的频谱切片共享及LTE的哪一频率范围和NR频率范围之间共享。
步骤404，根据业务需求参数、当前网络参数对应用业务切片的天线子切片参数进行调整。
在一示例性实施中，当子切片为天线子切片时，业务需求参数为目标吞吐量，当前网络参数为当前吞吐量；根据预设的吞吐量和天线数的对应关系，分别获取与目标吞吐量对应的目标天线数和与当前吞吐量对应的当前天线数；根据目标天线数和当前天线数的差值，对天线子切片的天线数进行调整；根据预设的吞吐量和单频点带宽的对应关系，分别获取与目标吞吐量对应的目标单频点带宽和与当前吞吐量对应的当前单频点带宽；根据目标单频点带宽和当前单频点带宽的差值，对天线子切片的单频点带宽进行调整。
在一示例性实施中，对天线子切片的天线数进行调整的举例如下：5G终端上的4G-5G 天线多达十多个，当终端工作在单频段SA模式时，最少2天线，最多4天线。当终端工作在NR CA模式时，如N41-N79,最多可达8天线，当终端工作在NSA模式时，天线数量还取决于当前LTE锚点数量。如B3(4)+N78(4)时，天线数量可达8天线，当B1(4)+B3(4)+B8(2)+N78(4)时，而B1和B3不共用天线时，天线数量可达14根。天线切片模块将终端天线模式分为单天线，双天线，三天线，N天线几种模式,设置某一个天线对应数量的极限吞吐为一定阈值，如500M以下对应2天线，500M-1600M对应4天线，1600M-2400M对应8天线，2400M以上对应10天线。终端通过内部驱动代码及配置文件，控制终端打开不同的4G-5G天线数量，以及打开天线的序列，从而进行基于天线数量的切片控制。
在一示例性实施中，对天线子切片的单频点带宽进行调整的举例如下：天线带宽包含单频点带宽及总支持带宽两部分，终端射频芯片对于TDD及FDD频段带宽，可支持5M、10M、15M、20M、30M、40M、50M、60M、70M、80M、90M、100M，如果对于载波聚合频段，还可以支持更高带宽如200M或更高。而终端对于某一个运营线或频段可支持的频段范围也各不同，如A运营商是FreA＝3500MHz-3600MHz,B运营商是FreB＝3400MHz-3700MHz,C运营商是FreC＝3300MHz-3800MHz，吞吐需求越高，所需的单频点带宽越高，吞吐需要支持的频点信道越多，所需的天线覆盖带宽越宽。这里通过天线匹配或天线调谐的调节，将天线工作频点切片到对应的需求范围内，而对于超出切片需求的频点、带宽及范围，则进行屏蔽或弱化。
在一示例性实施中，还可以对天线子切片的谐振频点深度进行调整，举例如下：当终端对某一个频段，频点或信道的天线效率有高需求时，可进行定点切片控制，调节天线匹配将此频点的谐振深度增强到目标阈值要求，直到信号强度或吞吐量满足阈值要求。
在一示例性实施中，本申请还可以根据当前网络参数调整应用业务切片或终端的工作模式。
在一示例性实施中，当前的业务需求大吞吐时，手机会切片进入大带宽，多mimo模式。当当前的业务需求在LTE下卡顿时，手机会切片进入NR模式，当NSA模式LTE锚点信号不稳定时，手机会切片进入SA模式。当当前的业务需求在LTE非CA下卡顿时，而5G NR信号差时，手机会切片进入信号强的LTE CA链路组合。当单NR都无法满足业务场景时，手机会切片进入LTE CA加上NR的组合模式，或NR CA模式。当当前的业务需求在某个SRS 1T2R模式下卡顿时，手机会切片进入信号质量更好的1T4R或2T4R SRS模式，当业务需求在SISO或主分集模式卡顿时，手机会切片进入NR MIMO模式，当当前的业务需求有上行卡顿或断续问题时，手机会切片进入功率优先模式。
实例1：若当前需要下载一个大流量游戏软件或程序、切片监控程序、以NR硬切片的mimo电路控制为例，如N78mimo切片控制，当用户需求是小流量及吞吐时，控制信号控制NR进入1*1mimo或2*2mimo模式，当用户需求是大流量及吞吐时，控制信号控制NR进入4*4mimo模式。当终端收到控制指令后，断开或导通N78相应的RX mimo电路及天线，RFC射频驱动配置，强制手机进入不同的MIMO切片模式，直到吞吐达到目标阈值要求。
实例2：SRS模式切片调节实例：针对当前需要峰值吞吐需求或峰值吞吐稳定性需求：进行终端侧的硬件或软件SRS切片控制。以NR硬切片的SRS方式为例，通过多路开关检测不同的网络及业务阈值切片需求，控制电路开关逻辑，将当前的终端SRS模式强制打到PMI、1T2R、2T4R和1T4R等几种模式。或采用软切片控制单元通过调用不同的SRS切片配置射 频驱动程序，具体地，在对应吞吐业务需求下，通过射频驱动代码RFC将终端设置成RFC_SRS_PMI、RFC_SRS_1T2R、RF3_SRS_1T4R、RFC_SRS_2T4R几种模式。
实例3：针对当前需要大上传吞吐的业务需求。可通过NR硬切片进行上行双发电路控制，以N78的上行双发,如果用户的上行业务较高，而当前的上传吞吐达不到用户业务需求，则可通过切片控制强制N78进入上行mimo双发传输模式，即tx1和tx2链路同时工作；如果用户的上行业务需求吞吐低，当前的上行吞吐有冗余，则可切片进入单NR发射模式。
