Description

波束测量方法、波束测量装置 技术领域
本公开涉及通信技术领域，具体而言，涉及波束测量方法、波束测量装置、电子设备和计算机可读存储介质。
背景技术
终端在与基站通过波束(beam)通信时，若终端需要切换波束，可以对基站的波束进行测量，进而根据测量结果选择合适的波束进行通信。
在传统的蜂窝网络中，基站的不同波束占用的频域资源是相同的，那么终端在切换波束时，测量不同波束就无需切换频域资源。
在非地面网络(Non-Terrestrial Networks，NTN)中，由于小区的覆盖面积非常大，同时调度的用户也很多，为了保证通信系统的性能，不同的波束占用的频域资源可以是不同的。
那么在非地面网络中，终端在切换波束时，测量不同的波束就需要切换频域资源，而切换频域资源需要的时间相对较长，容易造成通信延迟。并且在非地面网络中，发出波束的卫星是在高速运动中的，由于终端切换频域资源需要的时间较长，在此期间卫星已经运动到了其他位置，那么对于终端而言，卫星发出波束的情况已经发生了改变，切换波束可能发生失败，而切换失败后，由于原波束的情况也发生了变化，所以甚至还可能出现无法切换回原波束的问题。
发明内容
有鉴于此，本公开的实施例提出了波束测量方法、波束测量装置、电子设备和计算机可读存储介质，以解决相关技术中的技术问题。
根据本公开实施例的第一方面，提出一种波束测量方法，适用于终端，所述终端通过第一通信通道在第一波束上与网络通信，所述方法包括：
响应于确定对第二波束进行测量，通过第二通信通道对所述第二波束进行测量，其中，所述第二波束的频域资源与所述第一波束的频域资源不同。
根据本公开实施例的第二方面，提出一种波束测量装置，适用于终端，所述终端通过第一通信通道在第一波束上与网络通信，所述装置包括：
波束测量模块，被配置为响应于确定对第二波束进行测量，通过第二通信通道对所述第二波束进行测量，其中，所述第二波束的频域资源与所述第一波束的频域资源不同。
根据本公开实施例的第三方面，提出一种电子设备，包括：
处理器；
用于存储处理器可执行指令的存储器；
其中，所述处理器被配置为执行上述方法。
根据本公开实施例的第四方面，提出一种计算机可读存储介质，其上存储有计算机程序，该程序被处理器执行时实现上述方法中的步骤。
根据本公开的实施例，在通过第一通信通道在第一波束上与网络通信时，若需要对第二波束进行测量，可以通过第二通信通道对第二波束进行测量，从而无需调整第一波束的频域资源，以便快速地完成对第二波束进行测量，从而降低测量第二波束的时延。由于切换时延很短，在此期间卫星运动距离较短，所以对于终端而言，卫星的波束情况变化较小，因此有利于确保切换成功。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种波束测量方法的示意流程图。本实施例所示的波束测量方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站。
在一个实施例中，所述基站可以是地面基站，终端可以在非地面网络中通过空中设备与基站通信，所述空中设备包括但不限于卫星、无人机、空中平台等。后续实施例中主要在空中设备为卫星的情况下，对本公开的技术方案进行示例性说明。
在一个实施例中，空中设备可以在非地面网络中形成小区，并且向不同方向发出波束，空中设备可以通过发出的波束向终端发送下行信息，终端也可以通过发出波束向空中设备发送上行信息。
在一个实施例中，终端可以对空中设备发出的波束进行测量，例如在需要切换波束时，可以对当前所在波束(当前接收下行信息所用的波束)的邻波束进行测量，具体可以测量波束中携带的同步信号块SSB、信道状态信息参考信号CSI-RS等。
在非地面网络中，卫星发出的不同波束占用的频域资源可以不同，例如不同的波束可以占用不同的频点、带宽部分BWP等，例如第一波束和第二波束为非地面网 络中的波束，可以属于同一小区，也可以属于不同小区，第一波束和第二波束占用的频点不同。终端在需要切换波束时，当前所在的波束占用的频域资源与邻波束所占频域资源可以是不同的，例如当前波束占用的频域资源为频点f1，邻波束占用的频域资源为频点f2，终端的通信通道当前正在频点f1与卫星通信，为了对邻波束进行测量，就需要通信通道切换到频点f2。
在一个实施例中，通信通道至少包括终端中的射频收发模块，进一步还可以包括天线，例如通信通道可以是终端中的发送接收点。终端为了将通信通道从频点f1切换到频点f2，需要将射频收发模块收发信号的频点从f1调整到f2，这个调整过程一般耗时相对较长。
如图1所示，终端通过第一通信通道在第一波束上与网络(例如非地面网络中的空中设备)通信，所述波束测量方法可以包括以下步骤：
在步骤S101中，响应于确定对第二波束进行测量，通过第二通信通道对所述第二波束进行测量，其中，所述第二波束的频域资源与所述第一波束的频域资源不同。
在一个实施例中，终端当前所在的波束为第一波束，在第一波束上进行通信所使用的通道为第一通道，第二波束可以是第一波束的邻波束，也可以是卫星发出的不同于第一波束的任一其他波束，并且第二波束的频域资源与第一波束的频域资源不同，例如第一波束的频点和第二波束的频点不同，或者第一波束占用的带宽部分和第二波束占用的带宽部分不同。
在一个实施例中，在终端中除了设置有第一通信通道，还可以设置有第二通信通道，在需要对第二波束进行测量时，可以通过第二通信通道对第二波束进行测量，而对于第一通信通道占用的频域资源可以不做调整，仍然使用第一通信通道在第一波束上与卫星通信。
例如第一波束的频点为f1，第二波束的频点为f2，终端在使用第一通道在第一波束上进行通信时，第一通道的频点为f1。在终端需要对第二波束进行测量时，可以通过第二通信通道对第二波束进行测量。
其中，在对第二波束进行测量之前，第二通信通道可以处于启动状态，并且可以保持在频点f2进行通信；或者在对第二波束进行测量之前，第二通信通道处于未启动状态，在确定对第二波束进行测量时，启动第二通信通道，并将第二通信通道设置在频点f2进行通信；或者在对第二波束进行测量之前，第二通信通道已启动，但是处 于空闲状态，第二通信通道并不处于任何频点，在确定对第二波束进行测量时，将第二通信通道设置在频点f2进行通信。
据此，可以通过第二通信通道在频点f2对第二波束进行测量，在此过程中并无需将第二通信通道的频点从一个频点调整到另一个频点，所以可以快速地在频点f2对第二波束进行测量，从而降低测量第二波束的时延，而且也无需将第一通信通道的频点从f1调整到f2，可以继续通过第一通信通道在第一波束上与网络通信。
根据本公开的实施例，在通过第一通信通道在第一波束上与网络通信时，若需要对第二波束进行测量，可以通过第二通信通道对第二波束进行测量，从而无需调整第一波束的频域资源，以便快速地完成对第二波束进行测量，从而降低测量第二波束的时延。由于切换时延很短，在此期间卫星运动距离较短，所以对于终端而言，卫星的波束情况变化较小，因此有利于确保切换成功。
在一个实施例中，终端可以确定自身的位置信息，并根据确定的位置信息确定是否对第二波束进行测量，例如终端确定自身的位置位于第一波束的边缘，可以确定对第二波束进行测量。
在一个实施例中，终端可以对第一波束进行测量得到测量结果，例如参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Receiving Quality，RSRQ)，并根据测量结果确定是否对第二波束进行测量，例如RSRP低于第一预设功率，可以确定对第二波束进行测量。
在一个实施例中，终端可以在接收到网络侧发送的指示对第二波束进行测量的信令时，确定对第二波束进行测量。
在一个实施例中，终端可以周期性地对第二波束进行测量，那么可以在测量波束的周期开始时，确定对第二波束进行测量。
在一个实施例中，网络可以通过第一波束向终端发送测量资源，以供终端使用该测量资源在对第二波束进行测量，例如测量资源为第二波束中参考信号的时频资源，终端可以在该测量资源对第二波束中的参考信号进行测量。
在一个实施例中，第二通信通道可以是用于波束进行测量的专用通信通道。也即第二通信通道只用于波束测量，例如可以只用于对第二波束进行测量，而不用于波束测量以外其他通信操作。
在一个实施例中，第二通信通道可以是用于波束测量以外其他通信操作的通信 通道，其中，所述响应于确定对第二波束进行测量，通过第二通信通道对所述第二波束进行测量包括：
响应于确定对第二波束进行测量，且所述第二通信通道空闲，通过第二通信通道对所述第二波束进行测量。
在一个实施例中，在第二通信通道是用于波束测量以外其他通信操作的通信通道时，例如第一通信通道用于在非地面网络中通信，第二通信通道用于在地面蜂窝网络中通信，或者第二通信通道用于Wi-Fi通信，那么可以对第二通信通道进行检测，以确定第二通信通道是否空闲，若第二通信通道空闲，第二通信通道并不处于任何频点，可以通过第二通信通道对所述第二波束进行测量。
在一个实施例中，所述第一通信通道包括至少两个子通道，所述第二通信通道为所述至少两个子通道中的部分子通道。
在一个实施例中，第一通信通道可以包括至少两个子通道，例如每个子通道都是发送接收点，第一通信通道包括4个子通道，第二通信通道是4个子通道中的一个子通道，那么通过第二通信通道对第二波束进行测量，仍能保持第一通信通道中的3个子通道在第一波束上通信，有利于避免为了测量第二波束而中断在第一波束上通信所导致的通信中断。
图2是根据本公开的实施例示出的另一种波束测量方法的示意流程图。如图2所示，在一些实施例中，所述方法还包括：
在步骤S201中，根据对所述第二波束的测量结果确定从所述第一波束切换到所述第二波束。
在一个实施例中，通过第二通信通道对第二波束进行测量可以得到测量结果，进而可以根据测量结果确定是否从第一波束切换到第二波束，例如将测量结果与预设阈值相比较，根据比较结果确定是否从第一波束切换到第二波束。例如测量结果为RSRP，那么可以在RSRP高于第二预设功率，或者高于第一波束的RSRP时，可以确定从第一波束切换到所述第二波束。
图3是根据本公开的实施例示出的又一种波束测量方法的示意流程图。如图3所示，在一些实施例中，所述根据对所述第二波束的测量结果确定从所述第一波束切换到所述第二波束包括：
在步骤S301中，根据所述第二通信通道与所述第一通信通道的差异确定补偿 量；
在步骤S302中，根据所述补偿量补偿对所述第二波束的测量结果；
在步骤S303中，根据对补偿后的测量结果确定从所述第一波束切换到所述第二波束。
在一个实施例中，第一通信通道的波束方向和第二通信通道的波束方向可以有所不同，那么通过第一通信通道对第二波束测量得到的测量结果，和通过第二通信通道对第二波束测量得到的测量结果也会有所不同。
在一个实施例中，可以通过比较对第二波束的测量结果和预设阈值来确定是否从第一波束切换到所述第二波束，但是预设阈值一般是按照通过第一通信通道进行测量得到的结果设置的，那么将通过第二通信通道进行测量的测量结果与该预设阈值比较，比较结果相对于通过第二通信通道进行测量的测量结果与该预设阈值比较会存在差异，该差异可以体现在第二通信通道与所述第一通信通道的差异。
例如通过第一通信通道对第二波束测量得到的测量结果为P1，通过第二通信通道对第二波束测量得到的测量结果为P2，预设阈值为P0，其中P1大于P0，但是P2小于P0，在这种情况，直接根据测量结果P2和P0比较，就会得到错误的结果，从而对是否从第一波束切换到第二波束的结果产生误判。
在一个实施例中，所述差异包括但不限于：
所述第一通信通道与所述第二通信通道在波束方向上的差异、所述第一通信通道和所述第二通信通道在射频参数上的差异(例如插损、射频通道数)。
那么可以根据第二通信通道与第一通信通道的差异确定补偿量，以补偿通过第二通信通道对第二波束测量得到的测量结果，以确保将补偿后的测量结果与预设阈值比较能够得到得出正确的比较结果。
在一个实施例中，针对第二波束测量时，通过第一通信通道进行测量和通过第二通信通道进行测量的差异为P1，其中，可以是通过第一通信通道进行测量得到的测量结果比通过第二通信通道进行测量得到的测量结果大ΔP。该差异可以预先确定，例如终端根据内部算法实现，或者通过预先通过第一通信通道和通过第二通信通道分别对第二波束测量来确定。
那么针对通过第二通信通道对第二波束测量得到的测量结果P2，可以在P2的 基础上加上ΔP，得到补偿后的测量结果P2+ΔP，进而将P2+ΔP和预设阈值P0比较，可以得到正确的结果，确保正确确定是否从第一波束切换到第二波束。例如在上述P1大于P0，但是P2小于P0的情况下，将P2加上ΔP，P2+ΔP可以大于P0。
图4是根据本公开的实施例示出的又一种波束测量方法的示意流程图。如图4所示，在一些实施例中，所述方法还包括：
在步骤S401中，在从所述第一波束切换到所述第二波束之后，通过所述第一通信通道在所述第二波束上与网络通信。
在一个实施例中，在通过第二通信通道完成对第二波束的测量后，可以释放第二通信通道，然后在确定需要切换到第二波束的情况下，通过第一通信通道在第二波束上与网络通信。
图5是根据本公开的实施例示出的又一种波束测量方法的示意流程图。如图5所示，在一些实施例中，所述通过所述第一通信通道在所述第二波束上与网络通信包括：
在步骤S501中，确定通过第二通信通道对所述第二波束进行测量时，所述第二通信通道的第二波束方向；
在步骤S502中，响应于所述第二通信通道与所述第一通信通道之间的距离小于预设距离，设置所述第一通信通道的波束方向为所述第二波束方向，通过所述第一通信通道在所述第二波束上与网络通信；
在步骤S503中，响应于所述第二通信通道与所述第一通信通道之间的距离大于预设距离，通过所述第一通信通道的波束方向在所述第二波束方向的预设角度范围内扫描，以确定目标波束方向，设置所述第一通信通道的波束方向为所述目标波束方向，通过所述第一通信通道在所述第二波束上与网络通信。
在一个实施例中，虽然在切换波束后使用第一通信通道在第二波束上进行通信，但是对第二波束进行测量使用的是第二通信通道，所以在切换到第二波束后，一般并不能立即确定将第一通信通道的波束方向设置在什么方向上通信质量最好。但是由于使用第二通信通道对第二波束进行了测量，在测量过程中已经将第二通信通道的波束方向调整到了适于接收第二波束的方向，所以可以确定在通过第二通信通道对第二波束进行测量时，第二通信通道的第二波束方向，并根据第二波束方向来设置使用第一通信通道的波束方向，以在第二波束上进行通信。
在一个实施例中，可以确定第二通信通道与第一通信通道之间的距离，例如两个通信通道的射频模块之间的距离，或者两个通信通道的天线之间的距离。
在该距离较小时，例如小于预设距离时，第一通信通道和第二通信通道在相同波束方向上通信效果的差异较小，那么可以设置第一通信通道的波束方向为第二波束方向，也即设置第一通信通道沿用第二波束方向，进而通过第一通信通道在第二波束上与网络通信，以便确保较好的通信效果。
在该距离较大时，例如大于预设距离时，第一通信通道和第二通信通道在相同波束方向上通信效果的差异较大，直接设置第一通信通道沿用第二波束方向，可能难以保证很好的通信效果。但是一般情况下，终端尺寸有限，在第二通信通道上使用第二波束方向与第二波束通信效果较好，在第一通信通道上与第二波束通信效果较好的波束方向也不会与第二波束方向偏差很大，因此可以通过第一通信通道的波束方向在第二波束方向的预设角度范围内扫描，以确定目标波束方向，设置所述第一通信通道的波束方向为所述目标波束方向，进而通过第一通信通道在第二波束上与网络通信，以便确保较好的通信效果。
图6是根据本公开的实施例示出的又一种波束测量方法的示意流程图。如图6所示，在一些实施例中，所述第一通信通道在所述第二波束上与网络通信包括：
在步骤S601中，通过所述第一通信通道在所述第二波束上，使用预配置的资源与网络通信；
或者
通过所述第一通信通道在所述第二波束上，使用从所述第一波束切换到所述第二波束之前向网络请求的资源与网络通信。
在一个实施例中，在从第一波束切换到第二波束后，可以通过第一通信通道在第二波束上与网络通信。其中，通信所用的资源可以是网络预配置的，例如通过系统信息携带配置预先发送给终端；通信所用的资源也可以是终端向网络请求的，例如在切换到第二波束之前，终端在使用第一波束通信时向网络发送的请求，进而网络通过第一波束将资源配置给终端。据此，可以保证终端在切换到第二波束后，直接使用资源在第二波束上与网络通信，无需再次向网络请求资源，以便降低通信时延。
图7是根据本公开的实施例示出的又一种波束测量方法的示意流程图。如图7所示，在一些实施例中，所述方法还包括：
在步骤S701中，向网络发送能力信息，其中，所述能力信息用于向所述网络指示所述终端具有通过第一通信通道在第一波束上与网络通信时，通过第二通信通道对第二波束进行测量的能力。
在一个实施例中，并非所有终端都具有多个通信通道，而且即使具有多个通信通道，也并非所有终端都支持通过第一通信通道在第一波束上通信时，通过第二通信通道测量第二波束。所以终端可以先确定自身的能力，以生成能力信息，通过向网络发送能力信息，以告知网络，终端是否具有通过第一通信通道在第一波束上与网络通信时，通过第二通信通道对第二波束进行测量的能力。
与前述的波束测量方法的实施例相对应，本公开还提供了波束测量装置的实施例。
图8是根据本公开的实施例示出的一种波束测量装置的示意框图。本实施例所示的波束测量方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与基站通信，所述基站包括但不限于4G基站、5G基站、6G基站。
在一个实施例中，所述基站可以是地面基站，终端可以在非地面网络中通过空中设备与基站通信，所述空中设备包括但不限于卫星、无人机、空中平台等。后续实施例中主要在空中设备为卫星的情况下，对本公开的技术方案进行示例性说明。
如图8所示，终端通过第一通信通道在第一波束上与网络(例如非地面网络中的空中设备)通信，所述波束测量装置可以包括以下步骤：
波束测量模块801，被配置为响应于确定对第二波束进行测量，通过第二通信通道对所述第二波束进行测量，其中，所述第二波束的频域资源与所述第一波束的频域资源不同。
在一些实施例中，所述第二通信通道为用于波束进行测量的专用通信通道。
在一些实施例中，所述第二通信通道为用于波束测量以外其他通信操作的通信通道，其中，所述波束测量模块，被配置为响应于确定对第二波束进行测量，且所述第二通信通道空闲，通过第二通信通道对所述第二波束进行测量。
