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。
本申请的实施例涉及一种传输路径的控制方法，如图1所示，包括以下步骤：
步骤101，检测当前终端的业务需求和/或网络特征；
步骤102，根据当前检测到的业务需求和/或网络特征，匹配对应的传输路径调整模式；
步骤103，根据匹配的传输路径调整模式对射频芯片至天线的传输路径进行调整；其中，调整后的传输路径经过的器件数量小于调整前的传输路径经过的器件数量，或调整后的射频传导路径及走线短于调整前的射频传导路径及走线，或调整后的天线路径对应的天线覆盖频段少于调整前的天线路径对应的天线覆盖频段，传输路径包括射频传导路径和天线路径，天线路径用于天线选择。
本实施例的传输路径的控制方法，应用于无线通讯的终端，例如手机、平板、笔记本电脑等等。由于终端的功能日益复杂，例如，同一部手机要同时兼容蜂窝移动通信、WIFI、蓝牙、全球定位***(Global Positioning System，简称“GPS”)中的大部分功能，需要满足2G/3G/4G/5G的频段需求，覆盖频段从600M-6GHZ不等。为了追求更高的数据传输数率， 还需要实现多进多出(Multiple Input Multiple Output，简称“MIMO”)即多天线和多载波聚合(Carrier Aggregation，简称“CA”)技术。手机的频段会有30多个，天线10多个，每个频段例如B1频段又分为主集、分集、主MIMO和分MIMO四个MIMO通道，每个通道由于物理器件的不同，又会分成4-20多个分支路径，所以每个频段的射频传输路径可能有20多个。
终端的传输路径除了天线路径，还包括如图2所示的射频前端模块传输路径，本申请中终端控制的传输路径，即是指射频前端模块中的传输路径，从射频芯片至天线或者测试点(测试座)，还包括之间的前级开关、中间级低噪声放大器(Low Noise Amplifier，简称“LNA”)、后级开关，开线切换开关等。由于传输路径中包含很多开关，滤波器等，同时为了兼容载波聚合等共存需求，需要用到一些射频切换或合路器件，如3P3T开关、DP4T开关、SPDT开关、NPNT(多刀多掷开关)、双工器(DIPLEXER)、分频器(TRIPLEXER)，还有一些萃取器、功分器、合路器等，从而会导致损耗较大，所以许多传输路径在射频性能和数据性能上也往往不是最优的。
一些终端中，传输路径是固定单一的，当路径存在异常或由于其他需求时，终端无法通过旁路模式切换路径，要实现传输路径的旁路模式，只能通过重新对终端设置兼容电路更改贴片料单实现，因此，即使在一些使用场景下，传输路径的资源损耗较高，也无法更改传输路径。同时由于射频通道和传输路径的数量较多，需要各通道、传输路径走线及布局在面积有限的印制电路板(Printed Circuit Board，简称“PCB”)上，使其既满足一定的兼容性要求，又要满足一定的隔离度要求，以满足数据吞吐量和用户感受，从而导致整个传输路径的在设置时要考虑的因素较多，设置过程复杂。
本实施例中，根据当前检测到的业务需求和/或网络特征，匹配对应的传输路径调整模式，根据匹配的传输路径调整模式对射频芯片至天线的传输路径进行调整，由于传输路径每经过一个器件，必然伴随着***的资源损耗，而调整后的传输路径经过的器件数量小于调整前的传输路径经过的器件数量，或调整后的射频传导路径及走线短于调整前的射频传导路径及走线，或调整后的天线路径对应的天线覆盖频段少于调整前的天线路径对应的天线覆盖频段，传输路径包括射频传导路径和天线路径，天线路径用于天线选择，所以调整后的传输路径的性能高于调整前的传输路径的性能，因此，调整后的传输路径的资源损耗小于调整前的传输路径的资源损耗，从而减少通信***的资源损耗。
下面对本实施例的传输路径的控制方法实现细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。
在步骤101中，终端检测当前终端的业务需求和/或网络特征。
具体地，对于网络特征的检测，终端使用天线接收来自基站的通讯信号，经过滤波、信号放大等处理后进入射频主芯片变频，再传输给基带处理芯片，基带芯片将信号进行模数处理，换算成对应的网络参数，例如，如网络类型(如GSM、WCDMA、CDMA、LTE、NR等)、小区信息(如Cell info、PCI等)、频段(如B1/B3/N78/N41等)、信道号(Arfcn)或中心频点，以及信号质量参数，如信号强度(如RSSI、RSRP)、信噪比SNR、信道质量指示CQI、上行发射功率，还包括调度参数如DLRI数据流数、上行MCS、下行MCS、SRS轮询机制等等。终端通过对这些网络参数进行采集和对比，可得到不同传输路径下的网络信号质量差异，从而进行对应的传输路径控制。终端会将网络参数对应的关键字配置成相应的日志 LOG掩码集，通过***采集、过滤、汇总，得到关键参数然后上报。
在一个例子中，网络特征包括网络环境和/或传输路径的路径损耗，其中，网络环境包括以下网络参数指标之一或其任意组合：工作频段、工作频点、无线信号强度、上下行通话质量、数据吞吐量、误码率。
本实施例中，终端通过根据各种网络参数指示及其任意组合，进行传输路径的控制，可以使得调整后的传输路径贴合终端的网络情况，符合终端实际使用需要。
对于业务需求的检测，终端使用基带芯片采集射频芯片的工作模式，通过检测当前终端在通讯中的无线参数LOG，提取关键性参数及信息，例如，空口LOG信息和业务上报信息等。
在一个例子中，业务需求包括分集模式、多输入多输出MIMO模式、多载波聚合CA模式、非CA模式、下天线模式、非下天线模式、独立组网SA模式、非独立组网NSA模式、有谐波互调干扰模式、无谐波互调干扰模式、头手模式、自由空间模式、有共存模式、无共存模式中的任意一种或者任意组合。其中，上述需求信息具体有空口LOG信息和业务上报信息，如接收RX MIMO模式，具体RX1、RX2、RX3、RX4等模式，CA和非CA模式具体包括上行CA、下行CA、2CA、3CA、4CA、5CA等,下天线和非下天线模式具体包括上下天线ASDIV切换模式和非切换模式，有谐波互调干扰和没谐波互调干扰模式，头手和自由空间模式具体包括自有空间，左右头手等通话模式，有共存和没共存模式具体包括LTE、NR、WIFI等共存模式。
本实施例中，通过根据各种业务需求及其任意组合进行传输路径的控制，可以使得调整后的传输路径贴合终端的业务需求，符合终端实际使用需要。
在步骤102中，终端根据当前检测到的业务需求和/或网络特征，匹配对应的传输路径调整模式。具体地，当启用本实施例的传输路径的控制方法后，终端实时采集LOG参数集，并分析不同传输路径的不同时间的进行参数对比，终端根据检测及对比结果，根据当前的网络质量、业务需求、各路径***插损、干扰检测情况、上下天线的使用情况、进行计算，匹配选择最合适的调整模式及参数。
例如，以RX MIMO接收业务为例，如图3所示，4G和5G的传输路径非常多，不同传输路径的路径损耗不一样，不同传输路径性能相差大，就会导致信道均衡性差，如果一个4*4MIMO的四条通道性能不均衡，接收到的RSRP信号电平将不一致，严重时直接会影响双流或四流下的MIMO吞吐性能，即调制性能低，会导致误码率高，进而导致吞吐速率低。因此，当检测到当前终端处于4*4MIMO业务，且四路的RSRP不一致时，终端可以进行对应的传输路径调整模式，将丢失(Loss)大的路径损耗较小，或将丢失(Loss)小的路径损耗增大，以达到各路径损耗均衡，使用接收电平也一致，提高终端数据吞吐性能的目的。
在一个例子中，终端在预设的映射关系中查询与当前检测到的业务需求和/或网络特征对应的传输路径调整模式，得到匹配的传输路径调整模，其中，映射关系用于存储业务需求和/或网络特征，与传输路径调整模式的对应关系。
具体地，终端可以预先计算所需传输路径的***损耗，获取对应设置的传输路径调整模式。其中，终端可以通过两种计算方式，预先设置好传输路径调整模式，第一种是将各射频路径，器件，走线包括打孔的单个损耗建立成模型，统计当前经过哪些路标器件，将各单元损耗叠加起来，形成***损耗，如图4所示，B3频段从收发芯片发出，依次经过LNA、一 级开关、声表面波器件(Surface Acoustic Wave，简称“SAW”)、SP2T开关、Diplexer、DPDT、3P3T开关到目标测试座,这些器件单元的Loss加上中间走线，打孔的损耗，即是总体***损耗。由于***损耗中各单元元素的损耗，在频点确认，板材及线宽确定的前提下，都是已知的，因此，只要检测到经过的器件就可以计算出传输路径总体的损耗值。第二种方法是终端通过自动增益控制(Automatic Gain Control，简称“AGC”)电平扫描和参考信号接收功率(Reference Signal Receiving Power，RSRP)自扫描，或研发信令测试扫描，测试所有传输路径的***损耗，例如从芯片口A到测试点B,经过路径1，***损耗插损为S1ab,经过路径2，***损耗插损为S2ab，经过路径3，***损耗插损为S3ab，经过路径4，***损耗插损为S4ab，上述4个插损值写入保存在终端中以备调用。
本实施例中，通过在预设的映射关系中查询与当前检测到的业务需求和/或网络特征对应的传输路径调整模式，得到匹配的传输路径调整模式，由于映射关系用于存储业务需求和/或网络特征，与传输路径调整模式的对应关系，即，预先将业务需求和/或网络特征，与传输路径调整模式进行映射存储，供终端在实际对传输路径进行控制时，可以根据当前的业务需求和/或网络特征，查询获取到匹配的传输路径调整模式，实现终端自适应选择传输路径，减少通信***的资源损耗。
在步骤103中，终端根据匹配的传输路径调整模式对射频芯片至天线的传输路径进行调整；其中，调整后的传输路径经过的器件数量小于调整前的传输路径经过的器件数量，或调整后的射频传导路径及走线短于调整前的射频传导路径及走线，或调整后的天线路径对应的天线覆盖频段少于调整前的天线路径对应的天线覆盖频段，传输路径包括射频传导路径和天线路径，天线路径用于天线选择，即调整后的传输路径的性能高于调整前的传输路径的性能。
具体地，终端对传输路径进行调整可以是对无源器件、有源器件、线路、天线中的任意一种及其任意组合。
其中，无源器件的调整可以是对SAW及LTCC滤波器、开关(SPDT、DPDT、SP3T、SPNT、3P3T、4T4T、NPNT等)、nplexer分频器(Diplexer、Triplexer、mulplexer)、萃取器、陷波器、双工器、三工器、耦合器等器件的任意一种或多种的调整。
常规传输路径的线路需要经过很多中间器件，同时由于PCB走线空间的限制，还会穿层打孔，除了器件损耗增加，长走线和小孔，大孔的损耗也会很大，本实施例使用线路的调整，通过当前的网络情况和业务需求，选择传输线路，以减少由于走线大孔带来的损耗。例如，如图5所示，如果终端当前是处于头手模式，底部天线由于手握性能比较差，NR发射天线需要从底部切换到顶部，而由于发射信号从射频集成电路(RFIC)收发芯片出来，经过PA功放放大、射频前端开关、前级下天线切换开关、再经过长走线和打孔(即图中的Line1、Via1、Line2、Via2、Line3),到上天线切换开关，最后到顶部测试点及天线后，整体损耗非常大，即传导功率降低很多，如在底部的功率有24dBm,而顶部只有22dBm,此时，即顶部天线的效率优势比被传导功率抵消掉，此时，就可以调用线路调整功能，通过开关切换，绕开途径兼容其他目的的开关器件，直接从PA模组前端，经过RFLESS线路Line4到目标测试座，从而减少了长走线和打孔损耗，达到提升顶部最大发射功率的目的，进而优化了NR的上行通讯质量。
RFLESS，是本实施例新提出的一种电路设计概念，通过业务、性能、场景、干扰、天线，CA或MIMO需求，将射频链路中的部分电路、模组、器件、走线实时、自适应地跳过(BYPASS) 或省去，达到有针对性的重构电路设计的思想。主要通过芯片，模组，分离电路等的兼容电路或射频驱动软件设计，让射频收发信号切换到RFLESS传输路径上去，以节省路径损耗，器件插损，达到增强发射功率和提升接收灵敏度，进而达到提升通话质量和数据吞吐性能的目的。这里的RFLESS包含无源器件RFLESS、射频前端模组RFLESS、芯片内部RFLESS、前端模组外部RFLESS、SAW及LTCC滤波器等的RFLESS、开关器件的(SPDT、DPDT、SP3T、SPNT、3P3T、4T4T、NPNT)的RFLESS、nplexer分频器(Diplexer、Triplexer、mulplexer)的RFLESS、萃取器、陷波器的RFLESS、射频走线路径(微带线/带状线)的RFLESS等。
本实施例中，通过对无源器件、有源器件、线路、天线及其任意组合的调整，可以实现对传输路径进行调整，使调整后的传输路径的资源损耗小于调整前的传输路径的资源损耗，从而减少通信***的资源损耗。
在一个例子中，若对射频芯片至天线的传输路径进行的调整包括多个调整类型，则终端可以根据匹配的传输路径调整模式，获取各调整类型的优先级，优先采用优先级最高的调整类型，对传输路径进行调整，若调整后的传输路径的性能未满足预设要求，则按优先级从高到低的顺序，采用下一优先级的调整类型，对传输路径进行调整，直至调整后的传输路径的性能满足预设要求。
本实施例中，通过设置调整模式及传输路径调整模式对应的调整类型的优先级，调整传输路径时优先采用优先级最高的调整类型，对传输路径进行调整，若调整后的传输路径的性能未满足预设要求，则按优先级从高到低的顺序，采用下一优先级的调整类型，对传输路径进行调整，直至调整后的传输路径的性能满足预设要求，可以实现按照不同需要，定制不同的调整类型优先级，并在优先的调整类型不合适时，按优先级顺序切换调整类型，可以使传输路径的调整尽快完成，缩短调整耗费时间，减少调整过程中的资源损耗。
在一个例子中，终端可以根据匹配的传输路径调整模式，调用预设的射频驱动程序，其中，射频驱动程序被设置为对传输路径以设定的调整方式进行调整。在终端内部，预设有默认的射频驱动程序，被设置为控制终端使用默认传输路径传输，经过各射频前端器件。而这些路径往往没有针对终端的不同使用场景进行分别设置，往往损耗大且不适用于手机弱信号场景，或者不能满足对应的业务场景需求。本实施例中，通过设置射频驱动程序配置导通专门的传输路径，可以通过程序单元控制对应信号走特定的路径通道，例如CA业务流量走CA通道，非CA业务流量走非CA通道，没有干扰业务流量走SAWLESS通道，有干扰业务流量走SAW通道等。
对于终端天线，传统的射频天线大部分是集成了很多频段的，如NR和LTE合路、NR和WIFI合路、NR和LTE及GPS合路，这些合路一则通过合路器，合并到天线，而合路器本身有一定的损耗。同时，天线为了兼容NR和LTE、WIFI、GPS各制式的效率，或兼容单LTE和NR多频段的效率，每个谐振频点的性能不是最高。本实施例中，提供了三种RFLESS天线调节工作模式。方式一，对于单网RFLESS天线模式，主要针对多合路天线的场景，如果网络和业务模块侦测到当前的业务是SA NR only模式,而此时不需要用到LTE、WIFI、蓝牙和GPS，则控制模块会先控制合路器bypass到指定NR路径，同时控制天线寄生长度及耦合点到NR only制式范围。方式二，单频RFLESS天线模式，主要针对单制式无合路但多频段的场景，如果网络和业务模块侦测到当前的业务是中移B41模式，侦测周围小区或既往小区没有漫游到其他LTE频段的可能，即这段时间只会用到B41而不需要用到LTE B1、B3、 B5、B8等频段，则控制模块会控制天线寄生长度及耦合点到B41独立频段，甚至可以谐振到特定的频点，从而让特定频点的天线效率达到最高。方式三，单点RFLESS天线模式，主要针对宽带宽的NR频段，如频段N77/N78/N79，频率跨度分别为3300-3800MHz、3300-4200MHz和4400-5000MHz，如果终端检测到当前终端的工作在某个特定频点，或某个固定的信道，如N78的频点3700MHz，通过检测当前频段的工作带宽为100M，将可将天线的谐振频点及工作带宽缩减到当前指定的频点及带宽范围内，以提升当前工作信道、频点的天线效率及驻波比，即将天线的工作频点锁定到单点工作模式，而不是宽频工作模式，即当前的天线的覆盖及支持的频点不用覆盖全频段范围，而针对当前频段，具体工作的信道频点而调谐或改变天线匹配形式。
本实施例中，终端根据匹配的传输路径调整模式，调用预设的射频驱动程序，由于射频驱动程序被设置为对传输路径以设定的调整方式进行调整，从而可以实现按照不同需要，为不同的传输路径调整模式，定制不同的射频驱动程序，实现终端自适应选择传输路径。本实施例的方案可根据当前检测到的业务需求和/或网络特征，匹配对应的传输路径调整模式，根据匹配的传输路径调整模式对射频芯片至天线的传输路径进行调整，由于传输路径每经过一个器件，必然伴随着***的资源损耗，而调整后的传输路径经过的器件数量小于调整前的传输路径经过的器件数量，或调整后的射频传导路径及走线短于调整前的射频传导路径及走线，或调整后的天线路径对应的天线覆盖频段少于调整前的天线路径对应的天线覆盖频段，传输路径包括射频传导路径和天线路径，天线路径天线选择。此外，调整后的传输路径的性能高于调整前的传输路径的性能，因此，调整后的传输路径的资源损耗小于调整前的传输路径的资源损耗，从而减少通信***的资源损耗。
本申请的实施例还涉及一种传输路径的控制装置，如图6所示，包括：
检测模块601，被设置为检测当前终端的业务需求和/或网络特征；
匹配模块602，被设置为根据当前检测到的业务需求和/或网络特征，匹配对应的传输路径调整模式；
调整模块603，被设置为根据匹配的传输路径调整模式对射频芯片至天线的传输路径进行调整；其中，调整后的传输路径经过的器件数量小于调整前的传输路径经过的器件数量，或调整后的射频传导路径及走线短于调整前的射频传导路径及走线，或调整后的天线路径对应的天线覆盖频段少于调整前的天线路径对应的天线覆盖频段，传输路径包括射频传导路径和天线路径，天线路径用于天线选择。即调整后的传输路径的性能高于调整前的传输路径的性能。
在一个例子中，对射频芯片至天线的传输路径进行的调整包括以下之一或其任意组合的调整类型：无源器件的调整、有源器件的调整、线路调整、天线调整。
在一个例子中，调整模块603，还被设置为若对射频芯片至天线的传输路径进行的调整包括多个调整类型，则根据匹配的传输路径调整模式，获取各调整类型的优先级，优先采用优先级最高的调整类型，对传输路径进行调整，若调整后的传输路径的性能未满足预设要求，则按优先级从高到低的顺序，采用下一优先级的调整类型，对传输路径进行调整，直至调整后的传输路径的性能满足预设要求。
在一个例子中，调整模块603，还被设置为根据匹配的传输路径调整模式，调用预设的 射频驱动程序，其中，射频驱动程序被设置为对传输路径以设定的调整方式进行调整。
在一个例子中，匹配模块602，还被设置为在预设的映射关系中查询与当前检测到的业务需求和/或网络特征对应的传输路径调整模式，得到匹配的传输路径调整模式，其中，映射关系用于存储业务需求和/或网络特征，与传输路径调整模式的对应关系。
在一个例子中，业务需求包括以下之一或其任意组合，分集模式、多输入多输出MIMO模式、多载波聚合CA模式、非CA模式、下天线模式、非下天线模式、独立组网SA模式、非独立组网NSA模式、有谐波互调干扰模式、无谐波互调干扰模式、头手模式、自由空间模式、有共存模式、无共存模式。
在一个例子中，网络特征包括网络环境和/或传输路径的路径损耗，其中，网络环境包括以下网络参数指标之一或其任意组合：工作频段、工作频点、无线信号强度、上下行通话质量、数据吞吐量、误码率。
在一个例子中，如图7所示，检测模块601，包含有L1网络侦测单元，L2业务检测单元，L3路径损耗计算单元，匹配模块602，包含有L4 RFLESS模式匹配单元，调整模块603，包含有L5参数储存单元，L6 RFESS程序单元，L7自适应控制单元，L8 RFLESS无源单元，L9 RFLESS有源单元，L10 RFLESS线路单元，L11 RFLESS天线单元。
其中，L1网络侦测单元和模式匹配单元L4相连，被设置为侦测终端的网络环境(包括工作频段，频点，无线信号强度，上下行通话质量，数据吞吐量，误码率等网络参数指标)。例如，5G网络N78频段如走正常路径A,当前的信号强度为-90，4*4mimo只有3个数据流传输，下行MCS最高21，而走RFLESS路径B,对应的信号强度为-85，4*4mimo只有4个数据流传输，下行MCS最高27，则表明RFLESS路径B较好，终端应该切换到B路径下工作。
L2业务检测单元和模式匹配单元L4相连，被设置为侦测终端的业务需求(包括主分集模式或mimo模式，CA和非CA模式，下天线和非下天线模式，NSA和SA模式，有谐波互调干扰和没谐波互调干扰模式，头手和自由空间模式，有共存和没共存模式等)。L3路径损耗计算单元和模式匹配单元L4相连，被设置为计算所需通讯路径的***损耗。L4模式匹配单元和自适应控制单元L7相连，被设置为根据上述侦测及计算结果，匹配选择合适的RFLESS调整模式及方法。L5参数储存单元和自适应控制单元L7相连，被设置为各RFLESS模型参数，测试参数，校准参数和控制参数的存储(如各器件、芯片，模组，走线，打孔等的损耗参数存储)。同时，L5参数储存单元也被设置为控制后续各单元启动和关闭RFLESS动作参数的存储，以及被设置为RFLESS校准参数的存储。
L6RFLESS程序单元和自适应控制单元L7相连，被设置为RFLESS射频驱动程序的调用。例如，以LTE B1-B3-B7-B20的CA组合业务为例，如图8所示，非CA组合，2CA组合，3CA组合，4CA组合，所经过的器件不一样。非CA组合(B1)不需要经过双开或多开开关，dipLexer或tripLexer，而2CA组合(B1_B3)需要经过一个双开开关，3CA(B1_B3_B7)组合需要经过一个双开开关，外加一个dipLexer。4CA组合(B1_B3_B7_B20)需要结果一个双开开关和一个tripLexer。业务需求单元可以根据不同业务需求，检测当前的CA组合，自适应调用对应的RFC程序，进而控制不同CA组合下的RFLESS器件调节。
L7自适应控制单元与各RFLESS调节单元相连，被设置为根据当前网络情况和业务需求的自适应RFLESS算法及硬件的调整控制(包括RFLESS无源单元的调节控制、RFLESS有源单元的调节控制、RFLESS路径单元的调节控制、RFLESS天线单元的调节控制)。如图9 所示，自适应控制程序会根据下面的业务需求及网络特征，进行有针对性的自适应RFLESS调节控制，直到无线通话性能，上下行吞吐，误码率等达到目标要求。
在实际工作过程中，自适应控制程序还负责具体选取何种RFLESS调节措施的选取。如上，有无源，有源，路径，天线四种调节措施，而在实际应用中，会结合当前的网络侦测单元检测到的网络参数，及业务检测单元检测到的业务参数，对比改变前后的参数变化值，是上述四个部分的哪一部分在起主要的作用。如果是如前端插损相关，优先调用无源调节单元，如果是CA及单元内bypass电路有关，优先调用有源单元，如果是上下切换有关，优先调用路径调节单元，如果是天线性能相关，优先调用天线调节单元。如果相关参数不明显或比较多，上述四个调节可以逐一调节，也可以是两两组合，也更多个组合一起使用，直到满足网络性能需求。
L8 RFLESS无源调整单元与自适应控制单元L7相连，被设置为根据当前网络情况和业务需求的无源单元的RFLESS调整控制。L9 RFLESS有源调整单元与自适应控制单元L7相连，被设置为根据当前网络情况和业务需求的有源单元的RFLESS调整控制。L10 RFLESS线路调整单元与自适应控制单元L7相连，被设置为根据当前网络情况和业务需求的走线线路的RFLESS调整控制。L11 RFLESS天线调节单元与自适应控制单元L7相连，被设置为根据当前网络情况和业务需求的天线单元的RFLESS调整控制。
本实施例通过终端RFLESS电路及算法改进，能解决当前射频通道传输路径及配置灵敏度不高的问题，能减少***路径损耗，能提升各路径的均衡性，增强信号强度，改善天线性能，进而改善用户的通讯和数据业务性能，以提升手持的通话率，掉话率和数据业务。
在一个例子中，终端可以对SRS进行RFLESS控制：终端N41和N78由于是4*4MIMO，每个频段会有4个射频传输路径，TX、DRX、PRX-MIMO和DRX-MIMO，N41分别对应四个天线A1、A2、A3和A4，N78分别对应四个天线A5、A6、A7和A8；在电路设计上，N41和N78的天线路径之间需要做兼容设计，通过天线开关来实现，如SP2T、3P3T、4P4T等。当N78天线性能不好时，或当N78天线收到影响时，可以切换到N41的对应路径天线上去。
在一个例子中，终端可以进行抗干扰RFLESS控制：当LTE B3作为ENDC锚点时，B3的二次谐波会落到N78频段的对应信道频点上，从而导致N78的接收灵敏度恶化，N78和LTE B3的之间的隔离度越高，作为双连接下的谐波或互调影响就越小。如LTE B3的路径有L1、L2、L3、L4、L5、L6、L7共7条，其中B3的TX有G1和G2两条，N78的PRX有NP1、NP2、NP3、NP4共4条，则路径干扰单元会将所有的上述所有的组合都计算一遍，然后选择干扰最小的组合路径作为最后的ENDC工作路径。
在一个例子中，终端可以进行均衡路径RFLESS控制：当N78工作在高速吞吐4*4MIMO时，四个通道的信号强度必须相对均衡，不然吞吐性能就有由于失衡而降低。如NR N78的路径有M1、M2、M3、M4、M5、M6、M7共7条路径，检测对应的接收信号强度RSRP或RSSI值分别为R1、R1、R3、R4、R5、R6、R7、如果原来默认的路径强度是R1、R2、R3、R4、而比较起来不均衡，则可切换到更均衡的路径R1、R3、R5、R7上去，以提高各通道的均衡性和吞吐量。
本实施例提供一种RFLESS的5G终端装置，使用业务及干扰侦测算法，计算从芯片VCO到各测试座之间的路径损耗，可以精准地检测出各路径的损耗，再采集接收信号强度值，各 路MIMO的信号均衡性，及干扰等，从优选择最佳内部或外部射频路径。还能根据当前的上下天线切换情况，左右头手及握姿情况，实时选择RFLESS传输路径，使得终端可以始终处于低损耗、高增益的最优的射频和天线传输路径，以提升用户的通话质量和数据吞吐性能。
本申请的实施例还涉及一种终端，如图10所示，包括：至少一个处理器1001；与至少一个处理器通信连接的存储器1002；其中，存储器1002存储有可被至少一个处理器1001执行的指令，指令被至少一个处理器1001执行上述的任一实施例的传输路径的控制方法。
其中，存储器1002和处理器1001采用总线方式连接，总线可以包括任意数量的互联的总线和桥，总线将一个或多个处理器1001和存储器1002的各种电路连接在一起。总线还可以将诸如***设备、稳压器和功率管理电路等之类的各种其他电路连接在一起，这些都是本领域所公知的，因此，本文不再对其进行进一步描述。总线接口在总线和收发机之间提供接口。收发机可以是一个元件，也可以是多个元件，比如多个接收器和发送器，提供用于在传输介质上与各种其他装置通信的单元。经处理器1001处理的信息通过天线在无线介质上进行传输。在一些实施方式中，天线还接收信息并将信息传送给处理器1001。
处理器1001负责管理总线和通常的处理，还可以提供各种功能，包括定时，***接口，电压调节、电源管理以及其他控制功能。而存储器1002可以被被设置为存储处理器在执行操作时所使用的信息。
