  • One possible solution is to reduce high-frequency signal crosstalk through PCB wiring, that is, using PCB isolation to reduce intermodulation interference MSD.
  • inserting a ground wire or ground plane between two lines with serious crosstalk can provide isolation and reduce crosstalk.
  • the spacing between adjacent signal lines can be increased and the parallel length of the signal lines can be reduced.
  • the directions of the wiring should be perpendicular to each other, and other measures.
  • Method 2 Improve the antenna isolation of UE
  • Antenna isolation refers to the ratio of the signal transmitted by one antenna and the signal received by another antenna to the signal of the transmitting antenna. That is, the less one antenna receives the signal transmitted by the other antenna, the better the isolation between the two antennas and the lower the degree of interference.

When solving practical problems, the above methods are usually used in combination.

For example, when power level 3 is increased to power level 2 (that is, 23dBm is increased to 26dBm), the second-order intermodulation MSD can be increased from 26dB to 31.9dB, and the fourth-order intermodulation MSD can be increased from 26dB to 31.9dB. Can be increased from 8dB to 18.5dB.

  • Method 4 The network schedules a single uplink carrier to send uplink transmission
  • intermodulation interference may occur. If network equipment scheduling is used to limit uplink transmission to only one uplink carrier at the same time, and no uplink transmission is scheduled on another carrier, intermodulation interference can be effectively avoided and MSD reduced.
  • Method 5 Network scheduling to send and receive non-simultaneous uplink transmission and downlink transmission
  • the main cause of harmonic/harmonic mixed interference is that the UE needs to receive downlink transmission while sending uplink transmission, thus affecting the UE receiving sensitivity. Therefore, the network limits the same time to schedule uplink transmission without scheduling downlink transmission, and the UE sends uplink transmission without receiving downlink transmission; or, schedules downlink transmission without scheduling uplink transmission at the same time, and UE receives downlink transmission without sending uplink transmission at the same time, so that the UE can Reduce the impact on receiving sensitivity.
  • improving PCB isolation, improving antenna isolation, transmit power rollback, and network scheduling limiting single carrier uplink transmission can improve intermodulation interference MSD.
  • the ability to improve harmonic/harmonic mixed interference MSD is very small.
  • Increasing PA output harmonic suppression and network scheduling to limit non-simultaneous transmission and reception can improve harmonic/harmonic mixed interference MSD, but the ability to improve intermodulation interference MSD is very small.
  • the network does not know whether the MSD of the accessed UE can be improved, it has no way of knowing whether it needs to intervene on the UE through scheduling restrictions to reduce the MSD of the UE. For UEs that have already reduced the MSD on their own, the network does not need to further reduce the MSD. If the network blindly takes measures at this time, it will increase scheduling restrictions. For UEs that cannot reduce the MSD on their own, the network needs to take measures, but the network does not know the measures.

Description

通信方法和通信装置
本申请要求于2022年08月03日提交中国专利局、申请号为202210926439.1、申请名称为“通信方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信领域，并且更具体地，涉及一种通信方法和通信装置。
背景技术
接收灵敏度用于描述终端接收下行链路有用信号的最小信号接收功率。当终端的信号能量小于标称的接收灵敏度时，终端将不会接收任何数据，也就是说接收灵敏度是终端能够接收信号最小门限。在无线传输中，接收灵敏度类似于人们沟通交谈时的听力，提高信号的接收灵敏度可使无线产品具有更强地捕获弱信号的能力。这样，随着传输距离的增加，接收信号变弱，高灵敏度的无线产品仍可以接收数据，维持稳定连接，大幅提高传输距离。
然而在信号实际传输过程中，由于各种原因(例如，两个上行频段的信号落入下行接收频段中)使得终端的接收产生干扰，可能会导致终端的接收灵敏度恶化，即最大灵敏度下降(maximum sensitivity degradation，MSD)，MSD会对终端的下行通信产生影响，即影响终端的接收性能，因此需要终端和/或网络采取相应的措施对MSD进行改善。
一般情况下，网络和终端都可以改善MSD，但终端与网络之间无法进行信息交互，网络无法获知需要改善哪些MSD，以及无法确定是否需要采取措施改善MSD，从而无法有效的改善MSD，进而影响终端的接收性能。
发明内容
本申请实施例提供一种通信方法和通信装置，终端与网络之间可以通过第一信息进行交互，从而能够有效的改善MSD，进而提高终端设备的接收性能。
第一方面，提供了一种通信方法，应用于终端或终端中的模块，该方法包括：
确定对于第一频谱组合的最大灵敏度下降MSD改善的能力，第一频谱组合包括第一频段和第二频段，第一频段的频段号与第二频段的频段号不同；
发送第一信息，第一信息指示对于第一频谱组合的MSD改善的能力。
在本申请实施例中，终端可以向网络发送第一信息，该第一信息可以指示终端对于第一频谱组合的MSD改善的能力，使得网络可以获知终端的MSD改善的能力，从而可以根据该第一信息确定是否需要进一步改善MSD，对MSD进行有效的改善，从而可以提升终端的接收性能。
在一种可能的实现方式中，终端在确定对于第一频谱组合的最大灵敏度下降MSD改善的能力之前，该方法还包括：终端获取第一载波和第二载波，第一载波对应的第一频段与第二载波对应的第二频段构成第一频谱组合，第一频谱组合的关系为载波聚合，或者， 第一频谱组合的关系为双连接。也就是说，网络为终端配置载波聚合CA/双连接DC，双连接的模式可以包括EN-DC、NE-DC或NR-DC。
结合第一方面，在第一方面的某些实现方式中，第一信息包括MSD改善能力信息，MSD改善能力信息指示终端能够改善MSD，或者，MSD改善能力信息指示终端不能改善MSD。
在本申请实施例中，终端向网络发送的第一信息可以包括MSD改善能力信息，并且该MSD改善能力信息可以指示终端能够改善MSD或者指示终端不能改善MSD，从而使得网络接收第一信息后，确定终端能否改善MSD，若终端不能改善MSD，网络可以采取相应措施改善MSD，从而避免无法改善MSD，影响终端的接收性能。
结合第一方面，在第一方面的某些实现方式中，若第一MSD值小于或等于第一阈值，则MSD改善能力信息指示终端能够改善MSD；或者，若第一MSD值大于第一阈值，则MSD改善能力信息指示终端不能改善MSD；其中，第一MSD值为终端针对第一频谱组合的MSD值。也就是说，MSD改善能力信息基于第一MSD值确定。其中，第一MSD值可以理解为终端对于给定的频谱组合(例如，第一频谱组合)实际产生的MSD值。应理解，第一MSD值与终端对应，不同终端的第一MSD值可能存在不同。
可选地，第一阈值为预先定义的，或者，第一阈值是高层参数配置的，或者，第一阈值是通过DCI/MAC CE动态指示的，本申请对此不作限定。例如，第一阈值的取值可以为5dB、10dB等。
在本申请实施例中，若终端针对第一频谱组合的MSD值小于或等于第一阈值，则说明终端的第一MSD值(即终端改善的MSD值)满足一定的要求，此时可以上报MSD改善能力信息指示终端能够改善MSD，不需要网络再进行改善；若终端的第一MSD值大于第一阈值，则说明终端无法有效地改善MSD值，即改善的MSD值不能满足要求，此时可以上报MSD改善能力信息指示终端不能改善MSD，需要网络调度限制降低终端的MSD，提高终端的接收性能。
结合第一方面，在第一方面的某些实现方式中，若第一MSD值小于或等于第一阈值且第二MSD值大于或等于第二阈值，则MSD改善能力信息指示终端能够改善MSD；或者，若第一MSD值大于第一阈值，则MSD改善能力信息指示终端不能改善MSD；其中，第一MSD值为终端针对第一频谱组合的MSD值，第二MSD值为第一频谱组合预定义的MSD值，第一MSD值小于第二MSD值。也就是说，MSD改善能力信息基于第一MSD值和第二MSD值确定。第二MSD值可以理解为利用传统的RAN4对频段组合的假设和定义得到的MSD值。在特定功率等级下，对于给定的频段组合(例如，第一频谱组合)，该第二MSD值是固定的，是协议中预定义的。
可选地，第二阈值为预先定义的，或者，第二阈值是高层参数配置的，或者，第二阈值是通过DCI/MAC CE动态指示的，本申请对此不作限定。例如，第二阈值的取值可以为5dB、10dB等。
在本申请实施例中，终端可以根据第一MSD值和第二MSD值确定自身是否有能力改善MSD。若第一MSD值小于或等于第一阈值且第二MSD值大于或等于第二阈值，说明终端能够改善MSD，不需要网络再进行改善，终端可以向网络发送MSD改善能力信息指示终端能够改善MSD。若第一MSD值大于第一阈值，则说明终端不能有效改善MSD，因此，终端可以向网络发送MSD改善能力信息指示终端不能改善MSD。

可选地，第三阈值为预先定义的，或者，第三阈值是高层参数配置的，或者，第三阈值是通过DCI/MAC CE动态指示的，本申请对此不作限定。例如，第三阈值的取值可以为5dB、10dB等。

可选地，终端上报满足第二条件的MSD类型，第二条件为第一MSD值小于或等于第一阈值且第二MSD值大于第二阈值。
在一种可能的实现方式中，第一信息包括MSD改善能力信息和MSD类型信息。也就是说，终端在上报MSD改善能力信息时，可以上报对应的MSD类型信息，即终端能够改善哪些类型的MSD，或者终端不能改善哪些类型的MSD。在这种情况下，网络通过接收第一信息可以获知需要改善哪些类型的MSD和/或不需要改善哪些类型的MSD。

如背景技术中所述，在信号实际传输过程中，由于各种原因均会对UE接收信号产生干扰，可能会导致UE的接收灵敏度下降，即MSD，从而影响UE的接收性能。根据干扰原因的不同，MSD主要可以分为四类：互调干扰(inter-modulation，IMD)、谐波/谐波混合干扰(harmonic/harmonic mixing)、跨频带隔离(cross band isolation)或邻近干扰(Proximity)。
互调干扰是指LTE-NR双连接(E-UTRA-NR dual connectivity，EN-DC)或者上行载波聚合(uplink carrier aggregation，UL CA)等双上行频段组合中两个上行频段的二阶、三阶、四阶或五阶互调产物落入下行频段接收信号带内，两个上行频段的互调产物落入下行频段接收信号带内可以理解为，两个上行频段的频点经过计算可以得到n阶互调的频点，这个频点在UE下行接收频段的范围内，从而可能会对UE接收信号产生干扰，导致UE的接收灵敏度下降。其中，下行接收频段可以是产生互调的两个上行频段分别对应的下行频段中的一个，或者下行接收频段也可以指多于两个频段的CA/DC组合中的两个并发上行频段外的第三个频段的下行接收频段。
谐波/谐波混合干扰是指当UE支持的频段组合的发射机和接收机同时处于活跃状态时，谐波和/或谐波混合干扰会降低UE的接收性能。谐波干扰是指CA/DC频段组合的较低频段的上行二次、三次、四次或五次谐波落入较高频段中，对较高频段的接收产生干扰。谐波混合干扰是指CA/DC频段组合的较高频段的上行信号与较低频段的本振信号的二次、三次、四次或五次谐波混频落入较低频段有用信号接收带中，对较低频段的接收产生干扰。
跨频带隔离是指当UE发送上行信息的频带距离接收下行信息的频带很近，或由于频段组合中一个频段的上行信号由于滤波器在另一个频段的接收信号频率范围抑制度不足，存在上行链路到下行链路的干扰时，UE的接收灵敏度会下降。
邻近干扰是指同一频段的上行信号对接收频段信号的干扰。
此外，利用传统的RAN4对频段组合的假设和定义，得到的MSD值在很多频段组合超过10分贝(dB)，有些甚至会超过20dB，而过大的MSD不适合运营商部署CA/DC组合。以5G NR广泛应用的频段组合DC_3-n78为例，DC_3-n78表示频段3和频段n78做双链接DC。DC_3-n78在不同信道带宽下的MSD值如表1所示，其中，下行频段n78的信道带宽均超过10dB，当n78下行信道带宽为10MHz、15MHz和20MHz时，MSD值甚至超过了20dB。可以理解的是，终端的信号能量小于协议规定的MSD值时，终端将无法接收任何数据，因此当MSD值过高时，可能会影响终端的接收性能。因此，需要降低MSD值，即改善MSD。
表1
目前，针对MSD改善的方法比较多样，主要包括通过UE的硬件实现和网络调度两种主要方式。对于互调干扰MSD而言，可以通过调整UE的硬件或者通过网络调度实现 互调干扰MSD的改善，例如可以通过提高UE的印刷电路板(printed circuit board，PCB)隔离、提高UE的天线隔离度、提升射频器件性能(例如，功率放大器(power amplifier，PA)的线性度)、UE发射功率回退或者网络调度单上行载波加以改善。对于谐波/谐波混合干扰MSD而言，也可以通过调整UE的硬件或者通过网络调度实现谐波/谐波混合干扰MSD的改善，例如可以增加UE的PA输出谐波抑制、在PA输出端使用谐波抑制滤波器和网络调度限制非同时收发等。下面对各种改善MSD方法详细介绍。
方法一、提高PCB隔离
在PCB的高频线路布线时，信号线近距离平行走线会引入串扰，串扰是指没有直接连接的信号线之间的耦合现象。PCB板层的参数、信号线的间距、驱动端和接收端的电气特性以及信号线端接方式对串扰都有一定影响。一种可能的解决方法是通过PCB布线减少高频信号串扰，即用PCB隔离的方法降低互调干扰MSD。
例如，在串扰较严重的两条线之间插入一条地线或地平面，可以起到隔离的作用而减少串扰。又例如，在布线空间许可的前提下，可加大相邻信号线的间距，减小信号线的平行长度。再例如，如果同一层内的平行走线无法避免，在相邻两个层，走线的方向相互垂直等等措施。
方法二、提高UE的天线隔离度
天线隔离度是指一个天线发射信号，通过另一个天线接收信号与该发射天线的信号比值。即一个天线接收到另一个天线发射的信号越少，那么两个天线的隔离度越好，被干扰程度越低。提高天线隔离度的有效措施主要包括：阻挡法、正交极化法、抵消法和合适的天线布局。
其中，阻挡法是指在电磁耦合通道上设置障碍阻挡电磁耦合，例如抛物面天线加装裙边，其前后比指标比标准天线改善接近15分贝(dB)。正交极化法是指两副天线采用相互正交的极化，例如双工状态的天线，发射与接收分别采用两个正交线极化或者两个正交圆极化，以增大其隔离效果。抵消法是指在两个天线之间人为开辟另一耦合通道，使之与原耦合相互抵消，实现隔离效果的增强。最直接地，增大天线间距可提高天线隔离度，但实际上经常会遇到限制，特别是在移动终端上天线布局范围狭小的情况下，恰当的天线布局更为重要。在解决实际问题时，上述几种方法通常是综合使用的。
方法三、UE发射功率回退
UE发射功率的提升会引起MSD值的升高，例如，功率等级3提升到功率等级2(即23dBm提升到26dBm)，二阶互调MSD可以从26dB升高到31.9dB，四阶互调MSD可以从8dB升高到18.5dB。物理上行共享信道(physical uplink shared channel，PUSCH)的发射功率通过公式1确定，PCMAX,f,c(i)表示UE被配置的最大发射功率。当PCMAX,f,c(i)足够小时，UE会采用PCMAX,f,c(i)作为PUSCH的实际发送功率。
其中，PPUSCH,b,f,c(i,j,qd,l)表示PUSCH的发射功率，PO_PUSCH,b,f,c(j)表示开环基础功率控制参数，表示PUSCH所占的带宽，ab,f,c(j)表示路径损耗补偿因子，PLb,f,c(qd)表示基于路径损耗参考信号组qd测量得到的路径损耗，ΔTF,b,f,c(i)表示PUSCH 传输使用的编码调制方案(modulation and coding scheme，MCS)的调整值，fb,f,c(i,l)表示闭环功率调整值。
配置的最大发射功率PCMAX,f,c满足如下的边界限制：
PCMAX_L,f,c≤PCMAX,f,c≤PCMAX_H,f,c      (公式2)

PCMAX_H,f,c＝MIN{PEMAX,c,PPowerClass-ΔPPowerClass}    (公式4)
其中，PEMAX,c表示由网络配置的功率参数，PPowerClass表示最大UE功率/功率等级，ΔTTB,c表示additional tolerance，MPRc表示最大功率回退。
结合公式2至公式4可知，配置的最大发射功率的范围与最大回退功率(maximum power reduction，MPR)有关，MPR取值越大，配置的最大发射功率越小。因此，一方面UE可以自行确定较大的MPR值，降低UE的发射功率，从而降低MSD。另一方面，由于MPR的取值与功率等级、波形选取、调制方式和上行传输的频域资源分配有关。因此，较高的调制阶数，或者调整RB分配可以提升MPR，降低UE的发射功率，从而降低MSD。
方法四、网络调度单上行载波发送上行传输
对于UL CA/EN-DC这种双上行的频谱组合，如果两个上行载波上同时发送上行传输，可能会产生互调干扰。如果通过网络设备调度限制同一时刻只能在一个上行载波上发送上行传输，另一个载波上不调度上行传输，则可有效避免互调干扰，降低MSD。
方法五、网络调度非同时收发上行传输和下行传输
谐波/谐波混合干扰的主要原因是UE在发送上行传输的同时需要接收下行传输，从而影响UE接收灵敏度。因此，网络限制同一时刻，调度上行传输的同时不调度下行传输，UE发送上行传输的同时无需接收下行；或者，调度下行传输的同时不调度上行传输，UE接收下行的同时无需发送上行，从而可以减小对接收灵敏度的影响。
综上所述，不同类型的MSD的改善方法也各不相同，例如，提高PCB隔离、提高天线隔离度、发射功率回退、网络调度限制单载波上行传输这四种方式可以改善互调干扰MSD，而对谐波/谐波混合干扰MSD的改善能力很小。增加PA输出谐波抑制和网络调度限制非同时收发这两种方式可以改善谐波/谐波混合干扰MSD，而对互调干扰MSD的改善能力很小。
此外，不同厂商生产的UE性能不尽相同，一些UE能够达到改善MSD的要求，例如通过设计限制允许更大的PCB隔离，而有些UE不能改善MSD。但网络不知道哪些UE能够改善MSD，哪些UE不能改善MSD。这会导致两种结果，一是运营商避免部署MSD问题过于严重的频谱组合，可能包括n3+n78，n3+n41。然而这些频段是移动、联通和电信等国内运营商的主要频段，限制在这些频段上部署网络会大大影响运营商的收益。二是运营商仍然部署MSD较大的频段/频段组合，忽略MSD，不可避免地会影响UE的接收性能。
进一步地，网络既然不知道接入的UE能否改善MSD，便也无从得知是否需要通过调度限制对UE加以干预，降低UE的MSD。对于已经自行降低MSD的UE，不需要网络再进一步降低MSD，而此时网络若盲目地采取措施，反而会增加调度限制；对于不能自行降低MSD的UE，需要网络采取措施，但网络不知道该频段/频段组合的哪一种MSD 需要降低，也就无法采取合适的措施。
因此，本申请实施例提供了一种通信方法和通信装置，终端通过向网络发送第一信息，该第一信息用于指示改善MSD的能力，从而使得网络能够根据该第一信息确定是否采取措施，进而能够提升具有MSD问题的终端的传输性能。
图2是本申请实施例提供的一种通信方法。如图2所示，方法200涉及网络和终端之间的交互，该网络例如可以是图1中所示的接入网设备120和核心网设备110，该终端可以是图1中所示的终端设备130和终端设备140。该方法200具体可以包括S210和S220。
S210，终端确定对于第一频谱组合的最大灵敏度下降MSD改善的能力，第一频谱组合包括第一频段和第二频段，第一频段的频段号与第二频段的频段号不同。
应理解，由于不同终端的性能各不相同，有些终端能够达到改善MSD的要求，例如，通过终端自身的硬件设计允许更大的PCB隔离，在这种情况下，终端能够改善互调干扰MSD。也就是说，当确定第一频谱组合中的两个频段后，终端可以根据自身硬件情况确定对于第一频谱组合的MSD是否能够改善，即终端确定对于第一频谱组合的MSD改善的能力。
例如，第一频谱组合为CA_n3-n78，第一频段为n3，第二频段为n78，第一频段n3与第二频段n78进行载波聚合。CA_n3-n78频谱组合中可能同时存在互调干扰MSD和谐波干扰MSD。若终端自身的硬件设计允许更大的PCB隔离，则互调干扰MSD可能会得到改善，则终端确定能够改善CA_n3-n78频谱组合的互调干扰MSD。
S220，终端发送第一信息。相对应地，网络接收该第一信息。
应理解，该第一信息指示对于第一频谱组合的MSD改善的能力。该第一信息可以包括以下至少一项：MSD改善能力信息、MSD类型信息、频段信息、第一区间信息、第一行为信息、第二行为信息、同时收发能力信息、比例因子信息；或者，该第一信息可以包括以下至少一项：MSD改善能力信息、MSD类型信息、频段信息、第二区间信息、第一行为信息、第二行为信息、同时收发能力信息、比例因子信息；或者，该第一信息可以包括以下至少一项：改善能力信息、MSD类型信息、频段信息、第一MSD值、第三MSD值、第一行为信息、第二行为信息、同时收发能力信息、比例因子信息。
在一种可能的实现方式中，第一信息包括MSD改善能力信息，MSD改善能力信息指示终端能够改善MSD，或者，MSD改善能力信息指示终端不能改善MSD。
在一个实施例中，该MSD改善能力信息根据第一MSD值确定，第一MSD值为终端针对第一频谱组合的MSD值。第一MSD值可以理解为终端对于给定的频谱组合(例如，第一频谱组合)实际产生的MSD值。应理解，第一MSD值与终端对应，不同终端的第一MSD值可能存在不同。第一MSD值还与频谱组合对应，不同频谱组合的MSD值是独立确定的。例如，终端通过提升天线隔离度、PCB隔离等，提高原始MSD值(即提高第二MSD值)。此处的原始MSD值可以理解为利用传统的RAN4对频段组合的假设和定义得到的MSD值。在特定功率等级下，对于给定的频段组合(例如，第一频谱组合)，有固定的MSD类型及其对应的第二MSD值。
具体地，若第一MSD值小于或等于第一阈值，则MSD改善能力信息指示终端能够改善MSD；或者，若第一MSD值大于第一阈值，则MSD改善能力信息指示终端不能改善MSD。或者，若第一MSD值小于第一阈值，则MSD改善能力信息指示终端能够改善MSD；或者，若第一MSD值大于或等于第一阈值，则MSD改善能力信息指示终端不能 改善MSD。
可以理解的是，若终端针对第一频谱组合的MSD值小于或等于第一阈值，则说明终端的第一MSD值(即终端改善的MSD值)满足一定的要求，此时可以上报MSD改善能力信息指示终端能够改善MSD，不需要网络再进行改善；若终端的第一MSD值大于第一阈值，则说明终端无法改善MSD值，或者改善的MSD值不能满足要求，此时可以上报MSD改善能力信息指示终端不能改善MSD，需要网络调度限制对终端加以干预，降低终端的MSD。
在另一个实施例中，该MSD改善能力信息根据第一MSD值和第二MSD值确定，第一MSD值为终端针对第一频谱组合的MSD值，第一MSD值可以理解为终端对于给定的频谱组合(例如，第一频谱组合)实际产生的MSD值。第二MSD值为第一频谱组合预定义的MSD值，第一MSD值小于第二MSD值。第二MSD值可以理解为利用传统的RAN4对频段组合的假设和定义得到的MSD值。对于给定的频段组合(例如，第一频谱组合)，该第二MSD值是固定的，是协议中预定义的。一般情况下，第一MSD值小于第二MSD值，即终端改善了MSD值。其中，第一MSD值即为改善后的MSD值，第二MSD值即为原始MSD值。
具体地，若第一MSD值小于或等于第一阈值且第二MSD值大于或等于第二阈值，则MSD改善能力信息指示终端能够改善MSD；或者，若第一MSD值大于第一阈值，则MSD改善能力信息指示终端不能改善MSD。或者，若第一MSD值小于第一阈值且第二MSD值大于或等于第二阈值，则MSD改善能力信息指示终端能够改善MSD；或者，若第一MSD值大于或等于第一阈值，则MSD改善能力信息指示终端不能改善MSD。
可以理解的是，终端可以根据第一MSD值和第二MSD值确定自身是否有能力改善MSD。若第一MSD值小于或等于第一阈值且第二MSD值大于或等于第二阈值，说明终端能够改善MSD，不需要网络再进行改善，终端可以向网络发送MSD改善能力信息指示终端能够改善MSD。若第一MSD值大于第一阈值，则说明终端不能有效改善MSD，因此，终端可以向网络发送MSD改善能力信息指示终端不能改善MSD。
需要说明的是，上述的第一阈值和/或第二阈值为预先定义的，或者，第一阈值和/或第二阈值是高层参数配置的，或者，第一阈值和/或第二阈值是通过下行控制信令(downlink control information，DCI)/媒体访问控制控制单元(medium access control control element，MAC CE)动态指示的，本申请对此不作限定。例如，第一阈值和/或第二阈值的取值可以为5dB、10dB等。
示例性的，该第一信息可以包含1个比特，置0表示该第一信息中包括MSD改善能力信息指示终端设备不能改善MSD，置1则表示该第一信息中包括MSD改善能力信息指示终端设备能够改善MSD。
可以理解的是，该第一信息可以仅包括MSD改善能力信息。示例性的，当该第一MSD值下降到5dB及以下时，终端上报的MSD改善能力信息才指示终端能够改善MSD。但当第二MSD值从20dB改善到10dB时，由于第一MSD值(即改善后的MSD值为10dB)不能达到传输的要求(第一MSD值小于或等于5dB)，终端上报的MSD改善能力信息指示终端不能改善MSD，需要网络调度限制对终端加以干预，降低终端的MSD。
在另一种可能的实现方式中，第一信息包括MSD类型信息，MSD类型信息指示第一频谱组合的MSD的类型，MSD类型信息包括以下至少一种：二阶互调干扰、三阶互调干 扰、四阶互调干扰、五阶互调干扰、二阶谐波干扰、三阶谐波干扰、四阶谐波干扰、五阶谐波干扰、二阶谐波混合干扰、三阶谐波混频干扰、四阶谐波混频干扰、五阶谐波混频干扰、跨频带隔离。
在一个实施例中，MSD类型信息包括第一频谱组合中存在的所有的MSD类型。即第一频谱组合中存在的所有的MSD类型都上报给网络。可以理解的是，对于一种特定的频段组合，可能出现不少于两种MSD类型。例如，二阶互调干扰、四阶互调干扰、五阶互调干扰和谐波干扰同时存在于CA_n3-n78频谱组合中。
在另一个实施例中，MSD类型信息包括第一频谱组合中最大第二MSD值对应的MSD类型，第二MSD值为第一频谱组合预定义的MSD值。即上报MSD问题最严重的MSD类型给网络。
在另一个实施例中，MSD类型信息包括第一频谱组合中满足第一条件的MSD类型，第一条件为第一MSD值大于或等于第三阈值，第一MSD值为终端针对第一频谱组合的MSD值。也就是说，终端可以根据自身的第一MSD值，向网络发送第一MSD值大于或等于第三阈值对应的MSD类型。在这种情况下，说明终端也无法改善MSD，因此需要向网络发送无法进行改善的MSD类型，以便于网络根据第一信息中的MSD类型信息采取合适的措施。
需要说明的是，第三阈值为预先定义的，或者，第三阈值是高层参数配置的，或者，第三阈值是通过DCI/MAC CE动态指示的，本申请对此不作限定。例如，第三阈值的取值可以为5dB、10dB等。
在另一个实施例中，MSD类型信息包括第一频谱组合中第三MSD值不为零的MSD类型，第三MSD值为第一MSD值与第二MSD值之间的差值，第一MSD值为终端设备针对第一频谱组合的MSD值，第二MSD值为第一频谱组合预定义的MSD值，第一MSD值小于第二MSD值。也就是说，终端设备上报的MSD类型信息为改善了的MSD类型。
可选地，终端上报满足第二条件的MSD类型，第二条件为第一MSD值小于或等于第一阈值且第二MSD值大于第二阈值。
例如，若第一MSD类型满足：第一MSD值小于或等于第一阈值且第二MSD值大于第二阈值，则终端上报的MSD类型信息中包括第一MSD类型，即该第一MSD类型为终端已经进行MSD改善的类型。通过上报终端已经改善了的MSD类型，网络通过接收第一信息可以获知终端改善了哪些MSD类型，从而可以更有针对性的采取相应措施改善其他类型的MSD。
又例如，若第二MSD类型满足：第一MSD值大于第一阈值且第二MSD值大于第二阈值，则终端上报的MSD类型信息中不包括第二MSD类型，即终端虽然对第二MSD类型进行了改善，但第二MSD类型的改善程度不够。当网络接收的该第一信息后，该第一信息中不包括该第二MSD类型，说明终端没有对该第二MSD类型进行改善，需要网络采取相应的措施改善第二MSD类型。
再例如，若第三MSD类型满足：第一MSD值小于或等于第一阈值且第二MSD值小于或等于第一阈值，则终端上报的改善的MSD类型也不包括第三MSD类型，即第三MSD类型的原始MSD值不大(即第二MSD值不大)，终端和网络都不需要对第三MSD类型进行改善。
可选地，第一信息中可以包含8个比特，每个比特对应一种MSD类型，则第一信息 可以对应最多8个MSD类型。对于每一个比特，置0表示第一频谱组合不存在该比特对应的MSD类型，置1则表示第一频谱组合存在该比特对应的MSD类型。
在另一种可能的实现方式中，第一信息包括MSD改善能力信息和MSD类型信息。也就是说，终端在上报MSD改善能力信息时，可以上报对应的MSD类型信息，即终端能够改善哪些类型的MSD，或者终端不能改善哪些类型的MSD。在这种情况下，网络通过接收第一信息可以获知需要改善哪些类型的MSD和/或不需要改善哪些类型的MSD。
在另一种可能的实现方式中，第一频谱组合还包括第三频段，第三频段的频段号与第一频段的频段号不同，第三频段的频段号与第二频段的频段号不同，第一信息包括频段信息，频段信息指示第三频段，第三频段为第一频谱组合中受到MSD影响的频段。
在这种情况下，终端可以直接向网络上报受到MSD影响的频段，从而使得网络接收到第一信息后，可以确定受到MSD影响的第三频段信息，从而可以有针对性的改善MSD问题。
示例性的，若频谱组合中包括至少三个频段，第一频段和第二频段产生的MSD落在第三频段的接收带中，则终端设备可以上报第三频段的频段信息。例如，终端设备可以上报第三频段的频段号。
在另一种可能的实现方式中，第一信息包括第一区间信息，第一区间信息包括第一MSD值所属的区间，第一MSD值为终端针对第一频谱组合的MSD值。
可选地，网络侧和终端侧可以预定义或网络预配置一个MSD改善区间映射表(即第一MSD区间映射表)，该映射表可以包括终端上报值(reported value)以及上报值对应的第一MSD值区间范围。其中，该上报值可以为比特值，该第一MSD值区间范围可以为[0，N1)，[N1，N2)，[N2，N3)等，比特值与第一MSD值区间范围相对应。例如，终端上报0比特表示第一MSD值在[0，N1)范围内，终端上报1比特表示第一MSD值在[N1，N2)范围内。因此，当网络接收到上报的reported value后，可以根据MSD改善区间映射表确定第一MSD值的范围。
示例性的，MSD的改善区间的划分可以如表2或表3所示。其中，(N1，N2，N3，..N(m+1))的取值为预定义的或者预配置的。可选地，m＝3，(N1，N2，N3，N4)取值为(5，10，15，20)；或者，m＝7，(N1，N2，N3，N4，N5，N6，N7)取值为(5，10，15，20，25，30，35)；或者，m＝0，N1取值可以为5、10、15或20。

表3

可选地，该第一信息可以包括第一区间信息和MSD类型信息。也就是说，终端在上报第一区间信息时，还可以上报MSD类型信息，从而使得当网络接收到第一信息后，可以获知第一MSD值所属的区间以及该第一MSD值的类型，进而使得网络根据该第一信息更有针对性的采取相应措施改善MSD。
在另一种可能的实现方式中，第一信息包括第二区间信息，第二区间信息包括第三MSD值所属的区间，第三MSD值为第一MSD值与第二MSD值之间的差值，第一MSD值为终端针对第一频谱组合的MSD值，第二MSD值为第一频谱组合预定义的MSD值，第一MSD值小于第二MSD值。

示例性的，改善后的MSD值区间的划分可以如表2、表3或表4所示。其中，(N1，N2，N3，..N(m+1))的取值为预定义的或者预配置的。可选地，m＝3，(N1，N2，N3，N4)取值为(5，10，15，20)；或者，m＝7，(N1，N2，N3，N4，N5，N6，N7)取值为(5，10，15，20，25，30，35)；或者，m＝0，N1取值可以为5、10、15或20。

可选地，当第一频谱组合中存在互调干扰MSD，且第二MSD值较大，终端不能改善时，终端上报期待网络设备进行第一行为。对于UL CA/EN-DC，若在同一时刻两个载波都有上行资源，则网络仅在一个载波上调度上行传输。
可选地，当第一频谱组合中存在谐波/谐波混合干扰MSD，且第二MSD值较大，终端不能改善时，终端上报期待网络进行第二行为。对于FDD载波，不同时调度上下行，或者避免终端同时收发信息，或者收发信息之间有一定的隔离度。
需要说明的是，该第五阈值为预先定义的，或者，第五阈值是高层参数配置的，或者，第五阈值是通过DCI/MAC CE动态指示的，本申请对此不作限定。
在另一种可能的实现方式中，第一信息包括同时收发能力指示信息，同时收发能力指示信息指示第一频谱组合支持同时收发，或者，同时收发能力指示信息指示第一频谱组合不支持同时收发。
在一个实施例中，若第一MSD值大于或等于第一阈值，则同时收发能力指示信息指示第一频谱组合不支持同时收发；或者，若第一MSD值小于第一阈值，则同时收发能力指示信息指示第一频谱组合支持同时收发。
可以理解的是，若第一MSD值大于或等于第一阈值，则说明终端无法对MSD进行有效的改善，因此需要向网络发送同时收发能力指示信息指示第一频谱组合不支持同时收发，从而避免网络同时调度信号的接收和发送，进而避免对MSD产生进一步影响。
在另一个实施例中，若第二MSD值大于或等于第四阈值，则同时收发能力指示信息指示第一频谱组合不支持同时收发；或者，若第二MSD值小于第四阈值，则同时收发能力指示信息指示第一频谱组合支持同时收发。
可以理解的是，若第二MSD值大于或等于第四阈值，说明原始MSD值较大，如果仍然支持第一频谱组合同时收发的话，也可能会进一步影响MSD，因此，终端也需要上报同时收发能力指示信息指示第一频谱组合不支持同时收发。
在另一个实施例中，若第一MSD值小于或等于第一阈值，则同时收发能力指示信息指示第一频谱组合不支持同时收发，第一MSD值为终端针对第一频谱组合的MSD值。
可以理解的是，若第一MSD值小于或等于第一阈值，即终端对第一频谱组合中的MSD进行了改善，如果仍然支持同时收发信号的话，可能会对终端的第一MSD值产生影响，例如，使得第一MSD值变大，从而影响终端的接收性能。因此，在这种情况下，终端需要上报同时收发能力指示信息指示第一频谱组合不支持同时收发。
应理解，若终端在发送第一信息之前已经上报了支持同时收发的能力信息，则终端可以发送同时收发能力指示信息，指示该第一频谱组合不支持同时收发。若终端在发送第一信息之前没有上报支持同时收发的能力信息，则终端上报不同时收发的能力信息，或者，终端不上报与同时收发相关的能力信息，或者，终端可以发送同时收发能力指示信息指示该第一频谱组合不支持同时收发。
需要说明的是，第四阈值为预先定义的，或者，第四阈值是高层参数配置的，或者，第四阈值是通过DCI/MAC CE动态指示的，本申请对此不作限定。例如，第四阈值的取值可以为10dB、15dB、28.7dB等。

在一些实施例中，终端上报的第一信息包括终端的发射功率变化值与第三MSD值的比值。终端根据发射功率变化值与第三MSD值之间的关系，自行计算比例因子信息。示例性的，若终端的发射功率提升了2dB，MSD的值下降了4dB，则终端上报的比例因子为0.5。
在另一些实施例中，终端上报的第一信息包括发射功率变化值和第三MSD值，即终端分别上报终端的发射功率变化值与第三MSD值，网络根据第一信息计算比例因子信息。示例性的，终端上报的发射功率变化值为2dB，第三MSD的值为4dB，则终端网络计算得到的比例因子为0.5。
在另一些实施例中，网络和终端可以预定义或网络预配置比例因子映射表，该映射表可以包括终端上报值(reported value)以及上报值对应的比例因子区间范围，其中，该上报值可以为比特值，该比例因子区间范围可以为[0，0.2)，[0.2，0.4)，……，[0.8，1)，比特值与比例因子区间范围相对应。例如，终端上报0比特表示比例因子在[0，0.2)范围内，终端上报1比特表示比例因子在[0.2，0.4)范围内。因此，当网络接收到上报的比特值后，可以根据比例因子区间映射表确定比例因子的范围。
在另一种可能的实现方式中，第一信息可以包括MSD类型信息和比例因子信息。考虑到不同的频谱组合、不同的MSD类型，发射功率变化值与第三MSD值的比值会存在差异。因此，终端在上报给定频谱组合(例如，第一频谱组合)时，可以上报至少一种MSD类型对应的比例因子信息。当网络接收到该第一信息后，可以获知是哪种类型的MSD对应的比例因子，从而可以针对性的调整终端的发射功率。
应理解，上述的第一信息可以承载在MAC CE上发送给网络，也可以承载在PUSCH上发送给网络，本申请对此不作限定。
此外，网络接收到第一信息后，得知终端能够改善MSD，或者被改善的MSD类型，或者MSD的改善值。那么网络可以自行判断是否有必要进一步改善MSD。
可选地，网络判断不需要进一步改善MSD，则接收到第一信息后没有动作。若网络判断需要进一步改善MSD，则可以通过调度限制改善终端的MSD。
在一个实施例中，网络接收到第一信息后，得知终端不能够改善MSD，则网络采取相应的措施改善MSD。
具体地，网络接收到第一信息后，得知MSD值过大的MSD类型，则网络可以根据MSD类型采取相应的措施改善MSD。例如，若终端上报的MSD类型为互调干扰，则网络可以调度在单个载波或单个频段上发送上行传输，以降低该类型MSD；若终端上报的MSD类型为谐波/谐波互调干扰MSD，则网络可以不同时调度上下行传输，或者调度的上下行传输存在一定的间隔，以降低该类型MSD。
在另一个实施例中，网络设备接收到第一信息后，得知终端期待的网络行为为第一行为或者第二行为，那么网络依据终端的期待执行的第一行为或者第二行为相应的调度限制，即网络在单个载波或单个频段上调度上行传输，或者网络在第一频段组合中不同时调度上/下行传输，或者网络在第一频段组合中调度的上下行传输的具有一定间隔。
在本申请实施例中，终端可以向网络发送第一信息，该第一信息可以指示终端对于第一频谱组合的MSD改善的能力，使得网络可以获知终端的MSD改善的能力，从而可以 根据该第一信息确定是否需要进一步改善MSD，通过终端或者网络对MSD进行有效的改善，可以提升终端的接收性能。
