具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书、权利要求书或上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本申请实施例提供了一种SRS传输方法、终端及存储介质，获取终端的当前传输需求和终端当前的第一无线性能参数，根据所述当前传输需求确定无线性能参数阈值；当所述第一无线性能参数小于所述无线性能参数阈值，确定SRS的传输路径，并获取所述传输路径的信道质量参数；根据所述信道质量参数确定SRS的受干扰场景，根据所述受干扰场景调整所述传输路径。根据本申请实施例提供的方案，能够在当前的无线性能参数小于无线性能参数阈值时，确定SRS的受干扰场景，并根据受干扰场景对SRS的传输路径进行调整，能够减少SRS在传输路径中受到的干扰，使得基站接收到的SRS更加稳定，对终端分配更加准确的资源，进而提高终端的无线性能参数和传输性能。
需要说明的是，本申请实施例中所述的终端可以是任意类型，例如5G手机，平板电脑、等，也可以是客户前置设备(Customer Premise Equipment，CPE)等设备，能够通过SRS与基站进行通信，并且获取基站分配的资源确定无线性能即可，也可以应用于终端的天线选择路径模块，为了叙述方便，以下实施例的终端以5G终端为例进行原理性说明， 后续不再赘述。需要说明的是，本申请实施例并不对5G终端的组网方式、天线数量和收发方式作出改进，例如，组网方式可以是常见的非独立组网(Non Stand Alone，NSA)或者独立组网(Stand Alone,SA),天线数量可以根据组网方式确定，例如NSA可以是6根天线，SA可以是4根天线，收发方式可以是常见的1T2R(一根天线发射、一根天线接收)、2T4R(两根天线发射、，四根天线接收)或者1T4R(一根天线发射、四根天线接收)等，本实施例不多作限制，能够对SRS的传输路径进行调整即可，后续不再赘述。
需要说明的是，本申请实施例的SRS传输方法，体现在终端中可以是以可开启的功能形式存在，例如在终端中设置“SRS抗干扰模式”的功能，用户可以通过在终端的操作开启或者关闭该功能，也可以是终端中默认开启的系统功能，根据终端的实际情况确定具体方式即可，后续不再赘述。
下面结合附图，对本申请实施例作进一步阐述。
如图1所示，图1是本申请一个实施例提供的终端执行SRS传输方法的流程图，该SRS传输方法包括但不限于有步骤S100和步骤S200。
步骤S100，获取SRS的传输路径的信道质量参数。
在一实施例中，在带宽允许的情况下，终端是能够通过向基站发送SRS获取足够的无线性能资源，当第一无线性能参数小于无线性能参数阈值，则终端发送的SRS受到了干扰，导致获取的无线性能资源无法满足业务需求。需要说明的是，在终端的多根天线之间存在干扰或者互绕，SRS的天线选择或者汇报值可能会存在偏差，导致向基站汇报交叉的信号值，导致基站错误评估各天线通道的信道质量，从而给出较低的调度，本实施例仅对传输路径造成的干扰进行讨论，其他干扰类型不在本实施例讨论范围，在此不再赘述。
在一实施例中，传输路径的信道质量参数可以是上下行吞吐率、参考信号接收成功率(Reference Signal Receiving Power，RSRP)、信噪比(Signal Noise Ratio，SNR)、信道质量指示(Channel Quality Indication，CQI)、误码率、最高可支持的调制与编码策略(Modulation and Coding Scheme，MCS)等，能够体现信道质量的参数即可。可以理解的是，信道质量参数可以从终端的射频芯片模块和基带芯片模块中获取，也可以从调节解调器(modern)的汇报值中获取，例如从modern的上报日志中抓取对应的数值，具体方式根据实际需求选取即可，在此不再赘述。需要说明的是，为了获取信道质量参数，可以通过终端的信道预计算评估功能模块对终端各通道的发射和接收信号质量进行评估，例如通过对上行信道的信息进行评估得出上行信号功率，又如对下行各通道电平进行探测得出RSRP和SNR等参数，具体的数据获取方法可以采用现有的技术内容，本实施例并不涉及具体参数获取方式的改进，在此不多作限定。
在一实施例中，信道质量参数的获取还可以设定干扰权重参数，例如，信号在传输路径中的传导性能和天线效率等参数通常是固定已知的，设置为固定参数，而终端的使用场景和外界因素会造成一定的干扰，例如当前的手持方式、天线朝向、同频干扰等，因此可以在固定参数的基础上，设置干扰权重参数，干扰权重参数可以是预先设定的加权值，也可以是权重系数，例如在固定参数一定的情况下，若检测到手持方式为横屏，则获取与横屏所对应的干扰权重参数，同时根据固定参数和干扰权重参数对信道质量参数进行采集，从而使获取的信道质量参数更加符合实际情况，提高传输路径调整的准确性。
在一实施例中，获取信道质量参数之前，还可以对网络模式参数进行获取，例如检测 当前的SRS消息模式是1T2R、2T4R还是1T4R，组网模式是NSA模式还是SA模式，具体使用的空口制式等，根据具体的网络参数模式，能够确定具体采集的信道质量参数，例如在NSA模式下，还可以采集空口的频段及频点、带宽、调制方式、MIMO流数等网络参数，具体的网络模式参数获取方法可以采用现有的方案，在此不再赘述。
步骤S200，根据信道质量参数确定SRS的受干扰场景，执行与所确定的受干扰场景对应的调整策略。
需要说明的是，终端通常有多条天线，为了提高传输路径的使用效率，需要让终端通过SRS将每条传输路径的信号能力告知基站，使得基站分配更精准的资源到终端，因此，能够参与发送SRS的天线数越多，基站对信道能力的计算就越准确，终端能够获取的无线性能参数就更大，在这种情况下，天线之间造成的干扰也较多，因此需要通过信道质量参数先对SRS的受干扰场景进行确定，从而得出更加具有针对性的调整方法。
在一实施例中，对传输路径进行调整，可以通过在终端的干涉调节功能实现，根据受干扰场景确定具体的调整方案后，由干涉调节模块将传输路径调整后的方案发送至终端的控制模块，使得终端的控制模块根据传输路径调整后的方案发送SRS。需要说明的是，受干扰场景可以是任意数量，因此所得出的调整策略的数量可能是一个或多个，此时干涉调节模块可以是逐个调整方案应用，若调整后的无线性能参数满足无线性能参数阈值，则无需进行其他调整，也可以是多个调整方案协同作用，提高传输路径的调整效果，具体方式根据实际需求确定，能够使得调整后的无线性能参数满足无线性能参数阈值即可。
另外，参照图2，在一实施例中，图1所示实施例中的步骤S100执行之前还包括但不限于有以下步骤：
步骤S310，获取终端的当前传输需求和终端当前的第一无线性能参数，根据当前传输需求确定无线性能参数阈值；
步骤S320，当第一无线性能参数小于无线性能参数阈值，确定SRS的传输路径；
步骤S330，获取所确定的SRS的传输路径的信道质量参数。
在一实施例中，终端的当前传输需求可以通过常见的需求检测方法获取，例如，可以对终端中所有需要上传和/或下载数据的业务进行实时需求或者一段时间需求的统计，获取满足所有业务需求的带宽作为当前传输需求。可以理解的是，确定当前传输需求时也可以综合考虑当前终端所处的环境和用户的个性化需求，例如检测到终端所处的环境为地下或室内，由于信号受干扰的程度较大，可以在满足所有业务需求的带宽基础上进行适应性的增加，例如根据不同场景设置加权值等，又如，用户可以对终端的运行温度进行设定，避免数据流量过大时终端温度过高，本领域技术人员有动机根据实际情况调整具体的数值，具体方式并非本实施例作出的改进，在此不再赘述。
在一实施例中，无线性能参数阈值可以是能够满足业务需求的实时上传量和/或实时下载量，例如执行下载任务，无线性能参数阈值可以是终端所能达到的最大下载量；也可以是满足一段时间内业务需求的无线性能参数之和，例如通过终端观看视频直播，需要在一段时间内具备满足直播需求的上传量和下载量，无线性能参数阈值的具体选取方式根据终端的实际业务需求调整即可。
在一实施例中，第一无线性能参数在实际应用中可以是终端实时的上传量和/或下载量，当然也可以根据业务需求选取一段时间的无线性能参数，根据实际需求调整即可，在 此不再赘述。
另外，在一实施例中，信道质量参数包括上行信号功率；参考图3，步骤S200还包括但不限于有以下步骤：
步骤S400，当终端的每个信道的上行信号功率不同，确定受干扰场景为上行信号干扰场景。
在一实施例中，上行信号功率的采集可以通过在SRS的传输路径增加反馈检测电路实现，在终端的工作过程中，当检测到采集的上下行无线性能参数有异常的变化值，例如在某一瞬间降低导致无法满足业务需求，在这种情况下，通常是由于上行信号功率异常，可以确定受干扰场景为上行信号干扰场景。
另外，在一实施例中，信道质量参数包括信道功率；参考图4，步骤S200还包括但不限于有以下步骤：
步骤S500，当终端的每个信道的信道功率不均衡，确定受干扰场景为信道干扰场景。
在一实施例中，传输路径由于自身损耗的差异，路径发射功率和接收的RSRP之间存在差异，即信道的不均衡性，由于MIMO信道的不均衡，基站采集到的终端各通道的信号也不均衡，无法对终端进行均衡的资源分配，同时，由于不同信道存在差异，各路径的资源分布也不是最大，某一个路径上行信号较弱，则会分配较低无线性能资源，因此，当检测到终端的每个信道的信道功率不均衡时，可以确定受干扰场景为信道干扰场景。
另外，在一实施例中，信道质量参数包括传导路径质量参数；参考图5，步骤S200还包括但不限于有以下步骤：
步骤S600，当传导路径质量参数小于预设参考值，确定受干扰场景为传导路径干扰场景。
在一实施例中，由于终端具有多条天线同时发送SRS，因此需要在终端中设置天线选择模块，该模块中的路径为传导路径，传导路径质量参数可以通过信号强度进行计算，例如RSRP的差值、SNR差值、上下行误码率差值、最高可支持MCS调制方式差值、上下行无线性能差值等。需要说明的是，为了快速识别出干扰，可以针对每一个传导路径质量参数设定预设参考值，当计算出的传导路径质量参数小于预设参考值，则通过该传导路径发送SRS的效果无法达到预期，即存在干扰，因此可以确定受干扰场景为传导路径干扰场景，例如，终端检测到当前的模式为手握模式或者人头通话模式，对天线的收发有一定的影响，可以通过路径重组选择更优的传导路径。
另外，参照图6，在一实施例中，图3所示实施例中的步骤S400还包括但不限于有以下步骤：
步骤S410，调整上行信号功率；
步骤S420，获取终端在上行信号功率调整后的第二无线性能参数，当第二无线性能参数大于第一无线性能参数，将调整后的上行信号功率设置为传输路径的上行信号功率。
基于上述实施例，在SRS的传输路径中通过反馈检测电路获取各天线的功率后，可以对上行信号功率进行任意的调整，例如增大或者减小，增大上行信号功率后，可能会导致各通道之间的干扰增大，减小上行信号功率后可能会出现无线性能参数减少的情况，因此，本实施例并不对具体调整方向进行限制，而是对上行信号功率调整前后终端的无线性能参数进行对比，从而确定更适合当前SRS的上行信号功率。例如，检测到四条天线的上行信 号功率分别15dB、16dB、13dB和17dB，最大的上行信号功率为17dB，将四条天线的上行信号功率均设置为17dB，若调整后无线性能参数对比调整前有提升，则应用17dB作为SRS的上行信号功率，若调整后无线性能参数对比调整前有所降低，则进一步调整为16dB，依次类推，直至无线性能参数满足无线性能参数阈值，从而实现无线性能参数的提升。另外，通过上行信号功率调整使得无线性能参数提升后，还可以保存上行信号功率与无线性能参数之间的映射关系，以便在终端需求相同的情况下快速调整上行信号功率。
另外，参照图7，在一实施例中，图4所示实施例中的步骤S500包括但不限于有以下步骤：
步骤S510，获取预先设定的信道功率阈值；
步骤S520，根据信道功率阈值对终端每个信道的信道功率进行功率补偿；
步骤S530，根据功率补偿后的信道功率和所述信道功率阈值进行反馈调节，以使所述信道功率符合所述信道功率阈值。
基于上述实施例，传输路径中各信道保持均衡能够提高终端的无线性能参数，信道的均衡通常可以通过信道功率相同实现，因此可以预先设定好信道功率阈值，例如设定为17dB，若原始信号为15dB、16dB、13dB和17dB，通过简单的差值计算可知，对每个信道的信道功率的补偿值分别为2dB、1dB、4dB和0dB。
需要说明的是，功率补偿可以通过任意方式实现，例如对软件参数进行修改等。可以理解的是，为了提高传输路径的传输质量，可以实时自适应对信道功率进行功率补偿，例如实时检测每个信道的信道功率，每检测到一个信道不符合信道功率阈值时自动调整，也可以是完成一次遍历后进行统一的调整，具体方式根据实际需求选取即可，在此不再赘述。
另外，参照图8，在一实施例中，图5所示实施例中的步骤S600包括但不限于有以下步骤：
步骤S610，确定SRS的当前传导路径和可用传导路径，传导路径包括射频链路路径和天线路径；
步骤S620，分别获取当前传导路径和可用传导路径的传导路径质量参数；
步骤S630，当可用传导路径的传导路径质量参数大于当前传导路径的传导路径质量参数，将可用传导路径设置为SRS的传导路径。、
在一实施例中，由于终端需要通过多个天线发送SRS，因此传导路径调整通常以重组的形式完成，例如对SRS中的两个或者四个路径进行重组，例如通过射频扼流圈(Radio Frequency Choke,RFC)的切换进行路径匹配控制。需要说明的是，可用传导路径可以是除当前传导路径之外任意的可用路径，能够通过RFC切换完成路径重组即可。
在一实施例中，传导路径质量参数中的各种参数可以从modern的汇报值中获取，在本实施例步骤S620中，可以对任意数量和类型的参数进行获取和对比，也可以仅对小于预设参考值的参数进行对比，例如，获取到的SNR差值小于预设参考值，则获取当前传导路径的SNR差值，通过路径重组使用可用传导路径进行SRS的发送后，获取该传导路径的SNR差值，将两次SNR差值进行对比，若可用传导路径的SNR差值更优，保留路径的重组，否则重新选取另一条可用传导路径进行重组；当然，也可以将所有能获取的传导路径质量参数进行对比，得出综合的性能对比后选择更优的路径，具体方式根据实际需求选取，能够通过路径重组得出更高的信号质量、更大的吞吐率和更稳定速率的传导路径即可，在此 不再赘述。
另外，参照图9，在一实施例中，图1所示实施例中的步骤S200执行完成后还包括但不限于有以下步骤：
步骤S700，获取终端在传输路径调整后第三无线性能参数，当第三无线性能参数小于无线性能参数阈值，确定当前SRS的受干扰场景并根据受干扰场景调整传输路径。
在一实施例中，通过第三无线性能参数的判断，能够实现对传输路径的闭环反馈调节。传输路径的干扰通常不会保持恒定，在传输路径调整的过程中，可能会出现新的干扰，也可能调整的结果并不能准确达到无线性能参数阈值，例如，通过路径重组完成传导路径的调整后，新的传导路径信号之间可能会产生新的干扰，导致无线性能参数依然小于无线性能参数阈值，在这种情况下，可以通过获取传输路径调整后终端的无线性能参数，进一步与无线性能参数阈值进行比对并且执行传输路径的调整。
在一实施例中，闭环反馈可以在无线性能参数满足无线性能参数阈值后停止，或者已经达到终端所能实现的最大无线性能参数，根据终端的实际使用场景的信号质量确定即可，在此不再赘述。
另外，如图10所示，图10是本申请一个实施例提供的用于执行SRS传输方法的终端的功能模块示意图。
在终端200中，包括但不限于网络模式检测模块210、干扰检测模块220、控制模块230、信道预计算评估模块240、干涉调节模块250、路径重组模块260、功率反馈调节模块270、信道功率补偿模块280。其中，网络模式检测模块210与基站100和控制模块230通信连接，被设置成获取终端的网络模式参数；干扰检测模块220与控制模块230通信连接，被设置成采集终端200的信道质量参数，将采集到的信道质量参数发送至控制模块230中进行分析和处理；控制模块230可以是终端200中的芯片，或者是天线选择模块的处理器等装置，能够实现数据的分析处理以及响应干涉调节指令，根据确定好的调整方案对传输路径进行调整即可；信道预计算评估模块240分别与路径重组模块260、功率反馈调节模块270、信道功率补偿模块280和基站100通信连接，被设置成对终端200各通道的发射和接收信号质量进行评估，从而确定传输路径调整后所实现的无线性能参数；干涉调节模块250分别与路径重组模块260、功率反馈调节模块270、信道功率补偿模块280和控制模块230通信连接，被设置成获取路径重组模块260、功率反馈调节模块270或信道功率补偿模块280确定的调整方案，并向控制模块230发送干涉调节指令，使得控制模块230根据确调整后的传输路径收发SRS；路径重组模块260被设置成执行图8所示实施例的传导路径重组；功率反馈调节模块270被设置成执行图6所示实施例的上行信号功率的调整；信道功率补偿模块280被设置成执行图7所示实施例的信道功率补偿的调整。
在一实施例中，路径重组模块260的示意图可以参考图11所示，信号的传输从射频芯片的压控震荡电路(Voltage-Controlled Oscillator，VCO)开始，经过前级开关、中间级低噪声放大器(Low Noise Smplifier，LNA)开关模组、后级开关、天线切换开关，最后达到天线阵列，其结构示意图可以参考图11所示，根据VCO的不同，经过的各级开关路径不同，内外部硬件通道的兼容性不同，会形成不同的传导路径，因此在每一级开关进行切换，均可以实现两组或四组的传导路径重组，具体的开关切换方式和内部的电路并非本实施例作出的改进，在此不再赘述。
需要说明的是，终端200中的各模块能够实现相应的功能即可，可以是虚拟模块，也可以是现有的能够实现该功能的电路结构，本实施例不多作限定。
本领域技术人员可以理解的是，图10中示出的功能模块并不构成对本申请实施例的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
