技术领域
本申请涉及通信技术领域，尤其涉及一种波束推荐方法、装置、网络侧设备、终端及存储介质。
背景技术
随着低频段资源的变得稀缺，而毫米波频段具有更多的频谱资源，能够提供更大带宽，成为了移动通信系统未来应用的重要频段。
目前，在高频段传输的系统中，采用波束赋形传输可以实现更高赋形增益和更大覆盖。基站或终端通常以波束扫描的方式获得较优的波束赋形方向。波束扫描通过测量不同波束方向上的信号来获得较优的波束赋形方向。波束扫描的过程通常包括发送不同波束方向上的参考信号、信号质量测量、波束选择等过程。
但是，现有的波束扫描技术，要想获得多个波束方向上的最优波束，需要在多个波束方向分别发送参考信号，分别测量信号质量后选择最优的波束。天线数目越多，波束的方向性越强，波束方向越多，则需要的参考信号数目越多，开销越大，计算的复杂度也越高。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了便于清楚描述本申请实施例的技术方案，在本申请的各实施例中，若采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分，本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定。
随着低频段资源的变得稀缺，而毫米波频段具有更多的频谱资源，能够提供更大带宽，成为了移动通信系统未来应用的重要频段。毫米波频段由于波长较短，具有与传统低频段频谱不同的传播特性，例如更高传播损耗，反射和衍射性能差等。因此通常会采用更大规模的天线阵列，以形成增益更大的赋形波束，克服传播损耗、确保系统覆盖。对于毫米波天线阵列，由于波长更短，天线阵子间距以及孔径更小，使得可以让更多的物理天线阵子集成在一个有限大小的二维天线阵列中；同时，由于毫米波天线阵列的尺寸有限，从硬件复杂度、成本开销以及功耗等因素考虑，无法采用低频段所采用的数字波束赋形方式，而是通常采用模拟波束与有限数字端口相结合的混合波束赋形方式。
对于一个多天线阵列，其每根天线都有独立的射频链路通道，但共享同一个数字链路通道，每条射频链路允许对所传输信号进行独立的幅度和相位调整，所形成的波束主要通过在射频通道的相位和幅度调整来实现，称为模 拟波束赋形信号。而全数字波束赋形的天线阵列，每根天线都有独立的数字链路通道，可以在基带控制每路信号的幅度和相位。
目前，在高频段传输的系统中，采用波束赋形传输可以实现更高赋形增益和更大覆盖。基站或终端通常以波束扫描的方式获得较优的波束赋形方向。波束扫描通过测量不同波束方向上的信号来获得较优的波束赋形方向。波束扫描的过程通常包括发送不同波束方向上的参考信号、信号质量测量、波束选择等过程。
但是，现有的波束扫描技术，要想获得多个波束方向上的最优波束，需要在多个波束方向分别发送参考信号，分别测量信号质量后选择最优的波束。天线数目越多，波束的方向性越强，波束方向越多，则需要的参考信号数目越多，开销越大，计算的复杂度也越高。因此，在部署了超大规模天线的场景下，如何进行低开销、低复杂度的波束扫描是一个急需解决的问题。
由于模拟波束赋形时每根天线发送的信号一般通过移相器改变其相位，受限于器件能力的限制，模拟波束赋形都是整个带宽上进行赋形，无法像数字波束赋形针对部分子带单独进行赋形，因此，模拟波束赋形间需要通过TDM(Time Division Multiplexing，时分复用)方式进行复用。波束方向多意味着需要进行波束扫描的时间长。在高速移动场景下，信道环境变化快，最优的波束方向和服务站点变化也很快。如果仍然采用传统的波束扫描技术，有可能无法及时跟踪波束的变化情况，从而导致波束失败或无线链路失败，影响性能。
针对上述问题，本申请实施例提供一种波束推荐方法、装置、网络侧设备、终端及存储介质，以降低波束扫描的时间和开销。
本申请实施例提供的波束推荐方法、装置、网络侧设备、终端及存储介质可以应用在无线通信系统或无线与有线结合的系统。包括但不限于5G系统(如NR系统)、6G系统、卫星系统、车联网系统、演进型长期演进(Long Term Evolution，LTE)系统，上述系统的后续演进通信系统等。
本申请实施例提供的网络侧设备可以包含但不限于以下中的一种或多种：通常所用的基站、演进型基站(evolved node base station，eNB)、5G系统中 的网络侧设备(例如下一代基站(next generation node base station，gNB)、发送和接收点(transmission and reception point，TRP))等设备。
本申请实施例提供的终端有可以被称为用户设备等。终端包括单不限于手持设备、车载设备。例如，可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、上网本或者个人数字助理(Personal Digital Assistant，PDA)等。
下面通过具体实施例进行说明。
图1为本申请实施例提供的一种波束推荐方法的流程图，该波束推荐方法可以用于网络侧设备，比如，基站。如图1所示，该波束推荐方法包括如下步骤：
步骤110：确定用于波束推荐的波束数据库或波束模型。
具体地，在轨道交通或者城市道路交通场景下，由于轨道和道路的分布具有一定的规律性，其上的用户的活动局限于轨道或者道路规律，同样也具有一定规律性。用户运动的规律性会导致测量信息的规律变化。基站根据小区内所有用户上报的历史信息，可以得到这一规律。根据这一规律可以对当前用户进行波束推荐，从而达到节省开销的目的。
网络侧设备(比如：基站)基于网络所服务的用户上报的波束信息建立一个波束数据库或波束模型，当一个用户上报了波束质量信息时，网络侧可以根据用户的波束质量信息与数据库进行匹配，或者将用户的波束质量信息输入至数学模型，获得下行传输或上行传输的较优波束方向。其中，波束信息可以包括波束质量信息(如RSRP、BLER等)和/或波束标识信息。这里的参考信号质量信息可以为RSRP(Reference Signal Receiving Power，参考信号接收功率)、BLER(BLock Error Rate，误块率)等。
其中，网络侧设备可以针对每个终端分别建立波束数据库或波束模型；也可以建立适用于多个终端的波束数据库或波束模型。
步骤120：接收终端发送的用于波束推荐的第一波束信息。
具体地，第一波束信息可以包括终端采用上行传输方式得到的信息，比如：终端根据网络侧设备的配置或指示发送的用于波束质量测量的上行信号； 还可以包括采用下行传输方式得到的信息，比如：终端根据网络侧设备发送的下行信号进行测量，得到的下行信号对应的波束质量信息。
步骤130：根据第一波束信息、以及波束数据库或波束模型，确定用于信号传输的推荐波束和/或所述推荐波束的变化趋势。其中，所述信号传输包括上行信号传输或下行信号传输。
具体地，网络侧设备(比如：基站)可以将根据第一波束信息确定的波束质量信息与数据库进行匹配、比对、拟合、检索等操作，得到用于信号传输的推荐波束和/或所述推荐波束的变化趋势；也可以将根据第一波束信息确定的波束质量信息输入至波束模型，获得用于信号传输的推荐波束和/或所述推荐波束的变化趋势。
其中，推荐波束可以是根据第一波束信息、以及所述波束数据库或波束模型确定的较优波束。推荐波束的变化趋势可能是终端所在位置上推荐的多个波束的波束质量变化，也可能是终端在后续运动方向上的一个可能的波束变化，也可能包含终端在后续运动轨迹上一个或多个不同位置的较优波束。推荐波束的数量可能是一个或多个。当前确定的推荐波束可能与之前信号传输使用的推荐波束相同或不同。
另外，网络侧设备(比如：基站)根据终端上报的第一波束信息、与波束数据库或者波束模型确定用于信号传输的推荐波束和/或所述推荐波束的变化趋势的过程可以是一个迭代的过程。
当网络侧设备(比如：基站)初次根据终端上报的波束信息与波束数据库或者波束模型确定终端的一个或多个推荐波束，网络侧设备(比如：基站)在上述一个或多个波束上发送参考信号，比如：CRS(Cell Reference Signal，小区参考信号)，并指示给终端，终端监测这多个波束上的参考信号质量，比如：RSRP，并根据预定义准则将符合要求的波束信息上报给基站。网络侧设备(比如：基站)再次根据终端上报的信息与波束数据库或波束推荐模型确定推荐波束。重复上述过程。其中，预定义准则包括RSRP质量最好，或者接收质量大于一定门限值等。
比如：网络侧设备(比如：基站)可以在推荐的波束和该网络侧设备上 一次给终端发送用于测量的下行信号的波束上发送下行信号；终端接收上述波束上发送的参考信号，并根据预定义准则(比如：RSRP质量最好)将最优波束信息上报给网络侧设备；网络侧设备根据终端上报的波束信息选择较优波束。
由上述实施例可见，通过确定用于波束推荐的波束数据库或波束模型，在接收到终端发送的用于波束推荐的第一波束信息时，可以根据第一波束信息、以及波束数据库或波束模型，确定用于信号传输的推荐波束和/或所述推荐波束的变化趋势，从而解决了高速场景下频繁进行波束扫描过程带来的大开销与时延问题，节省了波束扫描时间和波束开销，还提高了波束推荐的效率和准确性。
进一步地，建立在上述方法的基础上，所述步骤110中的确定用于波束推荐的波束数据库或波束模型，可以采用但不限于以下实现方式：
(1-1-1)在指定时间段内获取指定区域内的所有终端上报的第二波束信息，所述第二波束信息中包括波束质量信息和/或波束标识信息；
(1-1-2)根据所述第二波束信息确定所述波束数据库或波束模型。
具体地，网络侧设备建立波束数据库时，可以对小区内所有终端采用下述过程。
下行过程：网络侧设备在一个或者多个波束上分别发送用于波束测量的下行信号，比如CRS、CSI-RS(Channel State Indication-Reference Signal，信道状态指示参考信号)等)，终端检测上述一个或者多个波束上发送的信号，并根据预设的准则将符合要求的波束信息上报给网络侧设备。网络侧设备将终端上报的波束信息存入波束数据库和/或根据终端上报的波束信息进行波束选择，将所选波束的信息存入波束数据库。
上行过程：网络侧设备配置或指示终端在一个或者多个波束上分别发送上行信号，比如：SRS(Sounding Reference Signal，上行探测参考信号)、PRACH(Physical Random Access Channel，物理随机接入信道)等，网络侧设备测量终端发送的所述上行信号，网络侧设备根据预设的准则向波束数据库存储测量结果和/或网络侧设备根据测量结果进行波束选择，将所选波束的 信息存入波束数据库。
其中，波束数据库中存储终端上报的波束信息的变化趋势(终端的运动轨迹和/或位置与波束质量信息和/或波束标识信息的关系)。可选地，网络侧设备还利用波束测量结果进行终端的位置和/或运动轨迹的估计，将终端的位置和/或运动轨迹存入波束数据库。可选地，波束数据库中存储着终端的位置和/或运动轨迹与波束测量信息的关系。
另外，网络侧设备建立波束模型时，可以对小区内所有终端重复采用建立波束数据库的过程进行信息收集，利用收集到的信息建立波束模型。比如：根据收集的信息数据确定用户的轨迹，根据轨迹信息确定波束模型。
由上述实施例可见，通过在指定时间段内获取指定区域内的所有终端上报的第二波束信息，所述第二波束信息中包括波束质量信息和/或波束标识信息，并根据所述第二波束信息确定所述波束数据库或波束模型，从而保证了的波束数据库或波束模型的可靠性。

进一步地，建立在上述方法的基础上，所述步骤210中的所述确定用于波束推荐的第一波束信息，可以采用但不限于以下实现方式：
(2-1-1)接收所述网络侧设备发送的网络侧配置信息或指示信息，所述网络侧配置信息或指示信息用于指示所述终端发送用于波束质量测量的上行信号。
具体地，用于波束质量测量的上行信号可以有很多种，比如：SRS、PRACH等。
(2-1-2)将所述用于波束质量测量的上行信号确定为所述第一波束信息。
由上述实施例可见，通过向网络侧设备发送用于波束质量测量的上行信号，这样网络侧设备就可以对上行信号的质量进行测量，得到上行信号对应的波束质量信息，进而根据该波束质量信息和波束数据库或波束模型用于信号传输的推荐波束和/或所述推荐波束的变化趋势，从而节省了波束扫描时间和波束开销。
进一步地，建立在上述方法的基础上，所述步骤210中的所述确定用于波束推荐的第一波束信息，可以采用但不限于以下实现方式：
(2-2-1)接收所述网络侧设备发送的用于波束质量测量的下行信号；。
具体地，用于波束质量测量的下行信号可以有很多种，比如：CSI-RS等。
(2-2-2)对所述下行信号的质量进行测量，并根据测量结果确定所述下行信号对应的波束质量信息和/或波束标识信息。
具体地，终端对下行信号的质量进行测量，可以获得下行信号中的一个或多个波束对应的波束质量信息。
其中，波束质量信息可根据需求包含测量的参考信号质量信息和/或波束标识、下行信号标识等。这里的参考信号质量信息可以为RSRP、BLER等。
(2-2-3)将所述下行信号对应的波束质量信息和/或波束标识信息确定为所述第一波束信息。
由上述实施例可见，通过接收网络侧设备发送的用于波束质量测量的下行信号，并对所述下行信号的质量进行测量，得到所述下行信号对应的波束质量信息，以及将所述下行信号对应的波束质量信息和/或波束标识信息发送至网络侧设备，这样网络侧设备就可以该波束质量信息和波束数据库或波束模型用于信号传输的推荐波束和/或所述推荐波束的变化趋势，从而节省了波束扫描时间和波束开销，降低了波束扫描过程带来的时延。
下面针对图1和图2所示的波束推荐方法，通过具体示例进行说明。
示例1：网络侧收集多个终端的波束质量测量信息，根据这些用户的信息建立终端的波束变化趋势数据库。通过一次或多次获得的波束质量信息和/或波束标识信息，获得终端的波束变化趋势，将该变化趋势与数据库进行比对后获得较优波束，从而提高了推荐波束的准确性。
示例2：网络侧收集多个终端的波束质量测量信息，根据这些用户的信息建立终端的波束模型。网络侧将一次或多次获得的波束质量信息和/或波束标识信息输入波束模型，获得较优波束和/或较优波束的变化趋势。
示例2的一种具体实现：终端在两次上报中分别上报了质量最好的M个波束的波束标识信息，网络侧存储了波束标识信息变化与较优波束/较优波束变化趋势的映射关系。网络侧根据该映射关系可以获得较优波束和/或较优波束的变化趋势。如表1：在这种映射关系下，假如终端第一次上报的波束标识为波束1、2、3，第二次上报的波束标识为波束2、3、4，则网络侧获知当前最优的波束为波束2，随着终端的移动，一定时间后最优的波束将变为波束3。
