Therefore, based on the above, it can be seen that for an omnidirectional radiation terminal, there are many disadvantages from the perspective of power and power consumption. But for a long time, the terminal has always been difficult to overcome this problem.

为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
在5G NR系统中，引入了毫米波工作频段，毫米波工作频率在10GHz以上。电磁波在毫米波频段的空间传播损耗非常大，导致电磁波信号的覆盖范围受限。为了克服大的空间传播损耗，终端设备以及基站在毫米波频段一般会采用由多个天线阵子组成的天线阵来形成窄波束以发射和接收信号，这些窄波 束相应具有比较强的指向性，如图2所示，基站201和终端202通过窄波束211和窄波束212进行通信，其中，窄波束211为基站的天线阵形成的波束，窄波束212为终端202的天线阵形成的波束。
对于使用低频段(通常指7.125GHz以下频段)的终端来说，通常采用的是全向天线，也即终端对外辐射的信号在空间是球状辐射，以满足终端的移动性要求。如图3所示，基站301的覆盖方位311也是采用大范围覆盖的方式，终端设备302辐射的信号在空间上是球状辐射312。。
相比于图2中的波束辐射方式，图3中的球面辐射具有更好的移动性效果，也即终端无论怎么移动都能够保持很好的连接。当然，问题就在于绝大部分的辐射功率都是无效的，只有被基站接收的很少功率是有效的。
终端设备在低频段采用的是全向辐射方式，其辐射的功率有效性很低。相比之下，终端设备在毫米波频段采用波束定向辐射方式，其功率能够有效的被基站接收。从终端设备的发射功率有效性角度看，需要进一步优化低频段的终端发射功率，也即减少无用功率的发射。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。

本申请实施例中，共站址或准共站址可理解为空间传播关系相同或空间关系相同或具有准共址(Quasi Co-Location，QCL)关系，表征第一基站的来波方向跟第二基站的来波方向可以认为是相同或类似的。
当第一基站和第二基站共站址或准共站址，终端设备可采用相同方向或类似的方向与第一基站和第二基站进行通信。
这里，第一基站与第二基站共站址或准共站址可理解为第一基站与终端设备进行通信的第一频段与第二基站与终端设备进行通信的第二频段共站址或准共站址，也就是说，第一基站使用第一频段辐射的信号的方向与第二基站使用第二频段辐射的信号的方向相同或类似。
终端设备检测第一基站的下行信号的测量结果，得到第一基站向终端设备发射下行信号的波束的波束方向即第一波束方向，第一波束方向指示第一基站向终端设备发射信号时的辐射方向，即第一基站相 对于终端设备的方向。

下面，与第一频段范围为毫米波频段、第二频段范围为低频段为例，本申请实施例提供的无线通信方法进行进一步说明。
如上所述，在NR系统中的低频段终端的发射功率的效率是很低的，绝大部分功率辐射到空中都没有被基站有效的接收，如图10所示，终端设备1001产生的球面辐射1002中，的只有面向基站1003的辐射功率才能被基站接收，而其他方向的功率都成了无用功率，甚至成了对邻近小区的干扰信号。
对于终端设备来说，其最重要的指标之一就是发射功率，因为通常情况下终端设备的功率放大器件的可放大能力是有限的，这导致了终端最大发射功率是有限的。此外，终端的电池的容量也受体积的限制造成可扩展能力有限。发射功率越大，则耗电越多。因此，综合上述可以看到，对于全向辐射的终端来说，从功率及耗电角度看是具有很多弊端的。但长久以来，终端始终难以克服该问题，原因之一就是终端是有移动性的且难以定位基站的方向，而只能采用最保守的策略，即全向辐射。
本申请实施例中，从降低无用辐射、减少耗电的角度，来对终端设备的信号辐射进行优化。
随着毫米波网络的部署，越来越多的终端设备同时具备了低频段与毫米波频段的发射与接收能力。毫米波具有良好的定向发射能力，因此，在部分场景下，对低频段与毫米波频段进行结合是一种可行的思路。一种典型的场景如图11所示，终端设备与毫米波基站1102进行通信，且与低频段基站1103通信，且毫米波基站1102与低频段基站1103共站址或准共站址部署。
共站址或准共站址可理解为空间传播关系相同或空间关系相同或具有准共址(Quasi Co-Location，QCL)关系，都是表征毫米波基站来波方向跟低频段来波方向可以认为是相同的，终端设备的低频段波束可以采用跟毫米波波束的方向相同或类似的收发方向进行。
这里，毫米波基站和低频段基站共站址或准共站址部署可由毫米波基站或低频段基站中的任一个告知终端设备。
本申请实施例中，对低频段波束的方向的调整可视为仅对终端设备的低频段发射波束做调整，也可为针对终端设备的低频段发射波束与低频段接收波束同时做调整。
在毫米波基站与低频段基站共站址或准共站址部署的网络场景下，低频段基站和毫米波基站位于同一位置或近似位于同一位置。终端设备通过接收来自毫米波基站的波束信号，就可以判断出对应的基站方向，并选择相应的毫米波发射波束进行通信，同时终端设备可以采用具有方向性的低频段天线与低频段基站进行通信，从而提升终端辐射功率的有效性，同时降低耗电。
本申请实施例提供的无线通信方法，涉及以下两个方面：
1、终端设备的低频段天线进行方向性辐射
低频段天线在设计的时候追求的是球面各方向都具有比较强的辐射，即各向均匀辐射球面，但这种各向均匀辐射球面实际带来的结果是终端天线不具有放大增益，而只能产生损耗，即图12所示的终端设备1201的辐射信号1202的功率1203小于输入信号1204的功率，其中，输入信号1204为终端设备的射频电路输入至终端设备1201的天线1205的信号。这导致天线为单纯的损耗，而没有放大增益。
相比之下，低频段天线也可以为具有方向性的辐射，如图13所示，当终端设备辐射的信号不是各向均匀时，其具有了方向性，并在这些方向上具有比各向均匀辐射更高的辐射功率，即图13所示的终端设备1201的辐射信号1202的功率小于输入信号1204的功率，但在图13所示的波束方向上的功率1206具有放大作用，也即相比之下具有了方向性增益。
其中，天线本身是不能放大信号的，只能有损耗，但对于具有方向性的天线来说，可以在某些方向具有放大作用也即天线增益但在其他方向上增益小于损耗，但总体表现出来是损耗。也即辐射信号小于输入信号功率。
通过辐射信号1202在图12中的功率1203和图13中的功率1206的比较可知，具有方向性的辐射相对于各向均匀的辐射，具有更高的辐射功率。
低频段终端设备产生方向性辐射波束的方式可包括以下至少之一：
在终端设备内部当具有多个低频段天线时，通过使用面向基站的方向性天线，可以提高终端设备辐射功率的有效性，并减少其他方向的干扰。
当终端设备内部只有一个天线时，通过使用不同的天线馈电点位置或激活不同的调谐电容等方式也可以激发出不同的天线辐射方向。
为了实现对具有方向性辐射能力的终端设备进行配置或调度等处理，该终端设备可将其低频段方向性波束产生能力(或称为低频段波束赋形能力)上报给基站，该能力是基于频段上报的，也即不同的低频段其可能具备方向性波束产生能力也可能不具备方向性波束产生能力。基站基于终端设备上报的能力可以识别具有该能力的终端设备及对应的频段。
在实现上面，如图14所示，终端设备1401在毫米波频段能够产生出各方向的波束，终端设备1401通过接收并测量基站1402的下行信号可以判断出毫米波基站1402发射信号的来波方向1403，并选择出合适的终端设备1401的波束1404来进行信号的接收与发射，。
进一步的，如图15所示，低频段基站1501与毫米波基站1502是处于共站址或准共站址关系，这样可以认为低频段基站1501的来波方向10511与毫米波基站1502的波束1503的来波方向是相同的，终端设备1504将低频段从全向性辐射1505调整为跟终端设备的毫米波信号指向1506相同的方向性信号1507。
2、低频段基站与毫米波基站的空间关系
低频段与毫米波频段可以通过CA或DC或EN-DC或NE-DC等方式组成频段组合来同时工作。对于图4所示的低频段与毫米波共站址或准共站址部署场景，为了实现终端的低频段方向性波束辐射，基站需要通过广播模式或无线资源控制(Radio Resource Control，RRC)专用信令等方式告知终端当前为共站址或准共站址网络部署场景。
共站址或准共站址部署可以理解为具有相同的空间传播关系，或具有相同的空间关系(Spatial relationship)等。
共站址或准共站址网络部署在信令实现上可以包括下述两种方式：
方式一、网络设备通过广播模式向小区内的所有终端设备广播
当通过广播模式来告知终端设备低频段基站与毫米波频段基站是共站址或准共站址部署时，可以是仅广播一个共站址或准共站址指示，且该指示适用于该基站支持的所有低频段与所有毫米波频段组成的频段组合；也可以是针对具体的频段组合广播共站址或准共站址部署。
对于方式一，网络设备不需要额外的指示终端设备某频段组合是不是为共站址部署，因为这个指示信息已经在广播消息中携带了。因此，网络设备可以直接给终端设备配置低频段与毫米波频段的频段组合即可，终端可自行参考系统广播消息，来完成低频段从全向辐射向方向性辐射的调整。
对于方式一，终端设备与基站的交互如图16所示，包括：
S1601、基站向终端设备广播低频段与毫米波频段为共站址或准共站址部署。
S1602、终端设备向基站上报低频段方向性波束产生能力。
S1603、基站向终端设备配置低频段与毫米波频段的频段组合。
S1604、终端设备调整低频段为方向性波束。
方式二、网络设备通过RRC信令告知终端设备当前的网络部署，该终端设备具有低频段方向性波束产生能力
共站址或准共站址部署的告知是基于频段组合进行的，在具体实现时可以是基站设备在给终端设备配置低频段(终端在该低频段具有方向性波束产生能力)与毫米波频段组成的频段组合时通过RRC信令携带给终端的，比如通过RRCReconfiguration消息携带给终端等，也可以是单独的RRC信令指示。
对于方式二，终端设备与基站的交互如图17所示，包括：
S1701、终端设备向基站上报低频段方向性波束产生能力。
S1702、基站向终端设备配置低频段与毫米波频段的频段组合，且携带低频段与毫米波频段为共站址或准共站址部署。
S1703、终端设备调整低频段为方向性波束。
本申请实施例提供的无线通信方法，能够实现终端设备低频段天线辐射从全向辐射调整为方向性辐射，以提高低频段终端的发射功率有效性，节省终端耗电。
