技术领域
本申请实施例涉及通信领域，特别涉及一种用于DSS的抗干扰方法。
背景技术
随着移动宽带网络业务流量需求的不断增加，频谱密集，且目前的低频段频谱资源几乎都被2/3/4G占据，由于2/3/4G，尤其是4G，将与5G长期共存，又无法全部重耕这些优质的低频段资源。运营商将2G/3G网络重耕到4G，从4G重耕到5G，已是大势所趋，如何从运营商的现有频谱资源挖掘更多潜力就成了业界普遍关注的议题。频谱共享技术能够实现在同一频段按需、动态地分配频谱资源，成为运营商的必然选择。动态频谱共享(Dynamic Spectrum Sharing，DSS)，就是允许4G长期演进(Long Term Evolution，LTE)和5G新空口(New Radio，NR)共享相同的频谱，并将时频资源动态分配给4G和5G用户，如图1所示。采用DSS技术后，能够提升频谱效率，且利于4G和5G之间平滑演进；既可利用旧4G的低频段资源和基站，也可实现4G向5G平滑演进，大幅降低5G投资成本。
尽管DSS对运营商来说非常有吸引力，但在技术上仍面临不少挑战，主要是信道间干扰问题。以4G/5G的DSS为例，4G为宽带***，信道配置相对粗放，控制信道、导频等均为全频带映射，而5G也为宽带***，同样存在各类物理信道，一些例子中通过预留缓冲带来解决两种制式之间的各种物理信道的 干扰，但通过预留缓冲带的方式会降低业务信道在DSS过程中整体频谱利用率。

本申请的第一实施方式涉及一种用于DSS的抗干扰方法，应用于电子设备包括，各种5G终端、客户前置设备(Customer Premise Equipment，CPE)、基站以及其他使用5G技术的产品等，具体流程如图2所示。
步骤101，获取实时的射频性能参数及通讯性能参数；
步骤102，根据射频性能参数及通讯性能参数判断是否存在动态频谱共享DSS的干扰，若存在，则进入步骤103；若不存在，则返回步骤101；
步骤103，根据射频性能参数及通讯性能参数对干扰进行分类；
步骤104，根据分类的结果，对不同类型的干扰执行对应的抗干扰处理，处理后返回步骤101进行判断检测。
下面对本实施方式的用于DSS的抗干扰方法的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，支持DSS功能的电子设备，通过内置于电子设备的测试算法，获取电子设备实时的射频性能参数及通讯性能参数。即，在获取实时的射频性能参数及通讯性能参数时不依赖于外置的测试仪表，不依赖于附加的射频模块及装置，如功分器，合路器，耦合器，耦合箱等，也不依赖于射频测试线缆，只通过自测算法及指令来实现，该自测算法位于电子设备程序内。例如：终端通过内置的测试算法，采集实时的功率，矢量幅度误差(Error Vector Magnitude，EVM)，邻信道抑制比(Adjacent Channel Leakage Ratio，ACLR)三个发射指标，同时也采集参考信号接收功率(Reference Signal Receiving Power，RSRP)及预估灵敏度(Sensitivity，SEN)两个接收指标。其中，射频性能参数例如：EVM，ACLR及RSRP及误块率(Block Error Rate，BLER)等；通讯性能参数例如：上下行吞吐量，误码率，调制与编码策略(Modulation and Coding Scheme，MCS)及多进多出(Multiple-In Multiple-Out，MIMO)数据流数等。
在步骤102中，根据上述获取的实时射频性能参数及通讯性能参数和预置的DSS无干扰下的射频性能指标及通讯性能指标阈值对比，判断是否存在DSS的干扰。例如，通过采集的上下行吞吐,MCS及误码率等指标，和预置的DSS无干扰状态下的指标阈值进行对比，超出预设范围则表明当前电子设备工作模式存在干扰。由于不同通信信道存在重叠，或者关系相邻状态，就会产生干扰，例如图3所示；其中01状态下会产生100％重叠干扰，02状态下会产生20％重叠带内干扰，03与04状态下会产生邻带干扰，05状态下会产生谐波干扰、交调干扰或杂散干扰等。
在一个例子中，以射频性能参数及通讯性能参数中的发射指标进行自测时，自测算法在终端空闲或待机时隙，发送控制指令，根据获取的实时发射指标，调用与实时获取的实时发射指标相同的EVM和ACLR指标值，控制终端的发射机进入自发模式；并闭环反馈采集发射机的发射指标EVM和ACLR指标，和预置的发射指标EVM和ACLR的阈值相比较，例如阈值EVM为3％，阈值 ACLR为-35dBc，当闭环反馈装置检测到发射机的发射指标EVM超过3％或ACLR超过-35dBc时，则判断当前存在DSS的干扰。其中，用于自测的发射指标EVM和ACLR还可由同相正交信号(In-phase Quadrature，IQ)取样计算预估得到。
在另一个例子中，以射频性能参数及通讯性能参数中的接收指标进行自测时，自测算法控制发射机发射与共享频谱频点相同，且信号接收电平相同的单载波(Carrier Wave，CW)参考信号，如发射-70dB的CELL POWER信号电平的连续单音波形信号，该信号可以是和共享频谱频点同频率信号，也可以是在共享频谱频点基础上附加一定频率偏移(如500Hz)的信号，发射机发射CW波后，接收机采集该CW波，进行解调和终端侧接收的信号强度指示(Recieived power，RX)/基站侧接收的信号强度指示(Received Signal Strength Indication，RSSI)计算，将读出的RSRP信号和发射的电平CELL POWER进行比较，判断差值，并与预置的阈值门限(如3dB)相比较，如果大于3dB,则可判断当前的共享频谱有干扰，需要调整NR的频谱频点到无干扰的位置；如小于3dB或接近于0,则可判断当前的共享频谱干扰无或可接受，不用调整频谱频点。其中，以射频性能参数及通讯性能参数中的发射指标和/或接收指标进行自测的示意图如图4所示。
另外，还能通过***软件算法抓取上述IQ采样值、***间的NF(Noise Factor，噪声系数)值及热噪声值，进而计算终端***从收发机到天线端之间的C/N载噪比，最后换算成SEN值；将上述接收机读出的RSRP值和换算后的SEN值，与参预置的DSS无干扰状态下对应的RSRP值和SEN目标阈值进行比较，以判断当前是否存在干扰。如预置的的DSS无干扰状态下N3得目标阈值RSRP是-70+/-2dB,对应的极限SEN是-93dBm/BW,而当N3处于共享频谱模式后，计算检测到的RSRP值是-65dB,计算出的SEN是-89dBm/BW，则表明当前是4-5dB的共享干扰。
在步骤103中，若经过上述判断后，结果为存在干扰，则根据实时获取的射频性能参数及通讯性能参数对干扰进行分类。在一个例子中，根据第一通信网络和第二通信网络的频点信息和ACLR对干扰进行分类，第二通信网络的网络速度大于所述第一通信网络的网络速度，例如，第二通信网络可为5G NR， 第一通信网络可为4G LTE。
在一个例子中，DSS干扰有谐波干扰，互调干扰，杂散干扰等。由于NR占用LTE频的频谱，有时甚至和LTE非常近甚至重叠，就会产生DSS干扰，通过计算LTE和NR的频点信息，同时监测ACLR共存杂散值，以识别干扰类型。如B1和N28的频点，如果是三倍频，就是谐波干扰，B1和N1同时工作时，如果频点很近，并且ACLR共存杂散值大于目标阈值，就是杂散干扰。
在步骤104中，根据分类的结果，对不同类型的干扰执行对应的抗干扰处理。针对不同干扰类型进行对应的处理，使得抗干扰的执行过程更加准确和高效。
如果不同调整参数下，上述超出阈值指标的参数有明显变化，则表明存在相关性，将其相关的大小记为相关系数，存储到内存中；通过干扰和调整参数的相关性，去调用对应的或相关性高的抗干扰措施。另外，存在相关性的AI学习过程，其步骤在一轮有效调节完成后。即有效调整措施和参数的模型建立过程，也就是DSS抗干扰参数模型库的自我学习过程，将每轮或最终的调整措施或参数和预定目标建立关联系数，如果有效，关联系数加1，如果无效，关联系数减1，通过不断的积累和学习，完善相关性的模型库，以便后续更加精准的抗干扰调节。
在一个例子中，通过调整动态功率中的发射功率，进行抗干扰处理，为了便于理解以下进行举例说明：
当NR工作于LTE频谱范围内时，LTE或NR的杂散会导致上下行误码率(Symbol Error Rate，SER)不同，进而导致吞吐性能恶化，所以通过需要消除杂散。杂散参数异常一种显著表现形式为实时获取的射频指标中LTE或NR的发射功率较高，已达到或接近最大发射功率，此时该功率下ACLR余量较小，EVM或杂散处于临界范围；调整发射功率能够同时影响ACLR、EVM及杂散，可对杂散干扰进行抗干扰处理。具体为：若检测到LTE的当前发射功率与其最大发射功率之差小于预设第一门限，则降低LTE的当前发射功率，提高NR的当前发射功率；若检测到NR的当前发射功率与其最大发射功率之差小于预设第二门限，则降低NR的当前发射功率，提高LTE的当前发射功率。在降低一侧发射功率时，通过升高另一侧发射功率进行补偿，如图5所示，从而在实现 抑制杂散的同时，也不影响总发射功率。例如：检测LTE和NR的实时发射功率，NR的发射功率为23dbm，已达到最大发射功率，LTE的发射功率为5dbm,此时对发射功率进行调整，降低NR的发射功率到20dbm，提升LTE的发射功率到8dbm(或其他较好的功率范围内)，在进行发射功率调整后，还可通过检测实时ACLR、EVM、SER或吞吐性能，校验是否完成针对杂散干扰的抗干扰处理。
在一个例子中，通过调整自适应调制参数，进行抗干扰处理。所述调制参数例如：MCS、起始资源块(Resource Block start，RB start)、资源块数(Resource Block number，RB nub)、Rank、子载波间隔(Sub-Carrier Spacing，SCS)等。
以SCS为例，LTE采用固定的15kHz的SCS，NR支持不同参数集的混合使用，即允许配置不同的SCS，如15kHz、30kHz、60kHz等。NR通过正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)信号的windowing/filtering技术降低了符号间干扰，但LTE没有windowing/filtering技术，导致NR与LTE进行频谱共享时，如果NR配置不同于15kHz的SCS时，会对LTE产生干扰，引起LTE的性能损失。所以首先检测当前的SCS是否正交，若不正交，则将NR的SCS调整为与LTE的SCS正交；如果出现NR的SCS无法调整、将SCS调整为正交后仍存在干扰或原未经过调整的SCS本处于正交状态，则调整其他自适应调制参数，直至检测到的实时射频指标满足预置的DSS无干扰下的阈值要求。
在一个例子中，若检测到信道频点重合或邻近，则根据信道约束算法对共享信道进行约束调整。在进行针对干扰的处理之前，限制LTE或NR的信道处于可用的范围列表内，通过进行信道限定，能够降低或消除干扰。例如，通过修改射频驱动配置文件，在模块的软件中引入信道限制机制。具体的，当检测到当前的电子设备处于NR的DSS工作模式时，通过LTE-NR的信道约束算法，限定LTE与NR的共存信道工作范围或清单，只有在约束范围内或指定可用清单内的信道才可共享，超出约束范围或指定清单内的信道不可用，需要调整至约束范围或指定清单内的信道。这里可以通过白名单或黑名单方式约束，如果是白名单方式，是指定LTE和NR的共享频谱信道值；如果是黑名单方式，则是指定LTE和NR不可同时使用的频谱信道值。其中，信道约束算法来自出厂 前的研发采集值，是基于大量数据模型的扫描采集值，扫描范围为对应频段的LTE全信道和NR全信道组合，通过采集不同信道组合下的射频指标值如EVM/ACLR/RSRP/BLER等，将满足预置的DSS无干扰下的阈值要求的信道列为可用信道。
其中，信道约束并不是静态的，而是动态可调整的，当LTE信道变化时，NR的信道也会随之变化。信道约束算法中的信道组合还具有实时更新功能，当有新的信道组合和条件产生，而此信道下有干扰，则该信道组合和条件也会自动添加存储在信道约束算法中，即能够自主实时学习补充，同时可接收并标记用户输入的可用信道组合和不可用信道组合，实时更新。
在一个例子中，对部分非复杂射频性能参数及通讯性能参数的变化预存有既定的处理方式，即在通过射频性能参数及通讯性能参数进行干扰判断时，若识别其为预存的干扰状况，则调用预存的该干扰对应的抗干扰方式，减少对非正常阈值范围内的参数进行动态计算，提高抗干扰的处理效率。
另外，预置在存储空间的数据还包括：NR和LTE不同频谱重合模式下的射频性能参数及通讯性能参数；不同信道范围内的NR射频指标值，如将NR信道划分为高中低HML三段，或根据ENDC下的干扰恶化程度，划分成ABCDEF多段。
本实施方式中，对于动态频谱共享过程产生的干扰，根据射频指标对干扰进分类，并根据分类结果执行对应处理，在没有降低频谱利用率的前提下，使得抗干扰处理更具有针对性，提高抗干扰处理效率；同时由于射频性能参数及通讯性能参数为实时获取值，能够在进行抗干扰处理后获取实时反馈，校验是否仍存在干扰，保证了抗干扰处理的完成度。也就是说，本申请实施方式能解决当前5G终端在DSS过程中的自干扰问题，能提升2/3/4G和5G NR的频谱抗干扰性能，防止动态过程中的冲突或干扰造成的发射指标恶化，接收大误码，进而提升终端5G峰值上传和下载吞吐率的性能效果。
本申请的第二实施方式涉及一种用于DSS的抗干扰方法，具体流程如图6所示。
步骤201，识别动态频谱共享的频段组合；
步骤202，根据识别的动态频谱共享的频段组合，判断是否可能存在动态 频谱共享DSS的干扰，若可能存在DSS的干扰，则进入步骤,203；若不可能存在动态频谱共享DSS的干扰，则结束流程；
步骤203，根据实时检测到的射频性能参数及通讯性能参数，判断是否存在干扰，若存在，则进入步骤204；若不存在，则回到步骤203；
步骤204，根据射频性能参数及通讯性能参数对干扰进行分类；
步骤205，根据分类的结果，对不同类型的干扰执行对应的抗干扰处理，处理后返回步骤203。
其中，步骤203至205与第一实施方式大致相同，为避免重复，不再赘述。主要区别之处在于步骤201和步骤202，以下对实施细节进行具体说明。
在步骤201中，获取实时的射频性能参数及通讯性能参数之前，还可以通过电子设备***软件抓取共享上报信息来识别动态频谱共享的频段组合，即NR和LTE的哪个频段共享频谱，如B1-N1，B3-N3，B28-N28，B66-N66，B71-N71等。
另外，识别电子设备当前是独立组网(Standalone，SA)还是非独立组网(Non-Standalone，NSA)模式，单NR模式，还是5G载波聚合(New Radio-Carrier Aggregation，NR-CA)模式。如果是NSA模式，还需要采集LTE与NR的双连接(E-UTRA-NR-Dual Connectivity,EN-DC)下的LTE和NR频段点信息，如果是NR-CA模式，还需要NR-CA的频段频点信息，如N3-N78；如果是4G长期演进载波聚合(Long Term Evolution-Carrier Aggregation，LTE-CA)加EN-DC模式，则需要同时采集LTE-CA及NR的频段频点信息，如B1-B3-N3-N78等。将识别结果存储至内存，作为进一步执行干扰识别及分类的辅助参考值。
在步骤202中，根据识别的动态频谱共享的频段组合，判断是否存在动态频谱共享DSS的干扰。如果识别结果为不存在动态频谱共享的频段组合，则说明不存在DSS的干扰，直接结束本流程，如果存在动态频谱共享的频段组合，则说明有可能存在DSS的干扰，则进入步骤203，根据实时检测到的射频性能参数及通讯性能参数，判断是否存在干扰。
在一个例子中，获取实时的射频性能参数及通讯性能参数前，检测第一通信网络和第二通信网络当前共享的频谱状态，其中第一通信网络可为LET，第 二通信网络可为NR。若LTE和NR当前不存在共享频谱，则不需要进行后续的用于DSS的抗干扰处理；若LTE和NR在当前共享的频谱并未同时工作或中存在频谱间隔(例如分别处于高低信道范围)，则干扰状态已知，调用预置的抗干扰参数进行处理即可，不需要获取实时射频性能参数及通讯性能参数用于判断、分类及对应抗干扰处理；若LTE和NR当前存在共享频谱，且LTE和NR在当前共享的频谱中不存在频谱间隔，即LTE和NR可能存在干扰，且该干扰状态非已知，不可控，所以需要获取实时的射频性能参数及通讯性能参数，并进行后续的判断、分类及对应抗干扰处理。通过该步骤能够识别预设的可控干扰，对于可控干扰的处理减少计算过程，提高处理效率，用于提升用户体验。
本实施方式中DSS状态下的***框示意如图7，其中共享检测模块L1用于依据共享上报信息来识别动态频谱共享的频段组合及工作模式；DSS干扰检测模块L2用于根据射频性能参数及通讯性能参数判断是否存在DSS的干扰；DSS干扰分类模块L3用于根据射频性能参数及通讯性能参数对干扰进行分类；预干涉调整模块L4用于调用预置的抗干扰参数处理已知的相对简单的干扰状态；实时计算调整模块L5根据获取的实时射频性能参数及通讯性能参数进行计算分析，并调用对应的抗干扰处理模块进行对应处理；共享信道约束抗干扰模块L6用于对信道进行约束调整；动态功率控制抗干扰模块L7用于处理杂散干扰；调制参数调整抗干扰模块L8用于处理谐波干扰和互调干扰；同时还存在参数存储模块(未示出)与各运算判断模块相连，对抗干扰处理的过程提供参数支持。
具体地说，参数存储模块可以包含以下信息：NR和LTE不同频谱重合模式下的不同射频收发指标值和场测指标值，即处于动态频谱共享模式下的指标参数值；不同信道范围内的NR射频指标值，如将NR信道划分为高中低HML三段，或根据随机接入4G5G双连接(EUTRA-NR Dual Connectivity，ENDC)下的干扰恶化程度，划分成ABCDEF多段；非动态功率共享模式下，不同目标发射功率的发射指标值，以及动态功率共享模式下的发射指标值；不同调制系数，如不同RB数，MCS、时隙SLOT下的发射指标值，以及不同接收增益及接收电平下的吞吐及误码值。预干涉调整模块L4，共享信道约束抗干扰模块L6，动态功率控制抗干扰模块L7和调制参数调整抗干扰模块L8，可以根据参数存 储模块中存储的参数进行抗干扰处理。
预干涉调整模块L4主要用于动态共享不是很复杂的情形下的抗干扰调整。如NR使用的频谱，同时间段使用的LTE没有同时在工作，而是其他LTE频段在工作，如N3工作时，B3没有工作，只有B1在工作。其次是，B3和N3同时工作，但是处于不同的频谱范围，B3处于低信道范围，而N3处于高信道范围，两者之间存在一定的频谱间隔。它们之间的干扰状态是已知的，即可调用预干涉调整模块L4，将LTE和NR限制在不同的频谱范围内，或调用L6-L8的抗干扰处理模块进行调整优化。
实时计算调整模块L5与L4、L6至L8各抗干扰处理模块连接，主要用于计算动态共享的情形下的抗干扰调整。当NR和LTE处于同频段交织下的频谱共享时，所处的频点是处于动态变化的，不易分割和预处理，此时则需要调用实时的计算调整模块，对当前的干扰进行实时监测计算，并将计算结果实时更新到参数存储模块中，同时也调用L6-L8的抗干扰处理模块进行调整优化。
本实施例中，首先检测第一通信网络和第二通信网络当前是否存在共享的频谱；在判断存在频谱共享后，进一步接收实时参数判断是否存在干扰，以及进行抗干扰处理。避免无用的接收DSS参数及进行干扰判断的进程，减少设备用于抗干扰处理的***资源占用。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本申请第三实施方式涉及一种用于DSS的抗干扰装置，如图8所示，包括：
获取模块301，用于获取实时的射频性能参数及通讯性能参数；
判断模块302，用于根据射频性能参数及通讯性能参数判断是否存在动态频谱共享DSS的干扰；
分类模块303，用于若存在干扰，则根据射频性能参数及通讯性能参数对干扰进行分类；
处理模块304，用于根据分类的结果，对不同类型的干扰执行对应的抗干扰处理。
对于获取模块301，在一个例子中，获取实时的射频性能参数及通讯性能参数前，检测第一通信网络和第二通信网络当前是否存在共享的频谱；若第一通信网络和第二通信网络当前存在共享的频谱，且第一通信网络和第二通信网络在共享的频谱中不存在频谱间隔，则再执行获取实时的射频性能参数及通讯性能参数。
对于判断模块302，在一个例子中，根据射频性能参数及通讯性能参数，与预置的DSS无干扰下的射频性能指标及通讯性能指标阈值对比，判断是否存在DSS的干扰。
对于分类模块303，在一个例子中，根据第一通信网络和第二通信网络的频点信息和临信道抑制比ACLR，对干扰进行分类；其中，干扰的类型包括：谐波干扰，互调干扰，杂散干扰；第二通信网络的网络速度大于第一通信网络的网络速度。
对于处理模块304，调整DSS中的动态功率，例如：检测第一通信网络和第二通信网络的当前发射功率；若第一通信网络的当前发射功率与第一通信网络的最大发射功率的差值小于预设第一门限，则降低第一通信网络的当前发射功率，提高第二通信网络的当前发射功率；若第二通信网络的当前发射功率与第二通信网络的最大发射功率的差值小于预设第二门限，则降低第二通信网络的当前发射功率，提高第一通信网络的当前发射功率。
调整自适应调制参数，例如：检测当前SCS是否正交；若SCS不正交，则将第二通信网络的SCS调整为与第一通信网络的SCS正交；其中，若SCS调整失败或SCS调整为正交后仍存在干扰，则调整第二通信网络的自适应调制参数。
若所述干扰为信道干扰，则根据信道约束算法，对共享信道进行约束调整；所述信道干扰为信道频点重合或邻近。
本实施方式中，对于动态频谱共享过程产生的干扰，根据射频指标对干扰进分类，并根据分类结果执行对应处理，在没有降低频谱利用率的前提下，使得抗干扰处理更具有针对性，提高抗干扰处理效率；同时由于射频性能参数及通讯性能参数为实时获取值，能够在进行抗干扰处理后获取实时反馈，校验是否仍存在干扰，保证了抗干扰处理的完成度。也就是说，本申请实施方式能解 决当前5G终端在DSS过程中的自干扰问题，能提升2/3/4G和5G NR的频谱抗干扰性能，防止动态过程中的冲突或干扰造成的发射指标恶化，接收大误码，进而提升终端5G峰值上传和下载吞吐率的性能效果。
