相关申请的交叉引用
本申请基于申请号为201910553389.5、申请日为2019年6月25日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此以引入方式并入本申请。
技术领域
本申请实施例涉及移动通信技术领域，尤指一种基于非独立组网NSA***的波束管理方法和装置。
背景技术
波束成形技术是5G通信的核心技术之一。波束成形技术会对无线信号的能量产生聚焦，形成一个精确指向性波束(Beam)，产生更强的信号增益来克服路损，从而为5G无线信号的传输质量提供了强有力的保障。
采用波束成形技术之后，通常波束越窄，信号增益越大，但相应的覆盖区域就越小，一旦波束的指向偏离用户，用户反而接收不到高质量的无线信号，所以，5G基站须使用多个不同指向的波束才能完全覆盖小区。在下行过程中，基站依次使用不同指向的波束发射无线信号，根据用户反馈确定对准该用户的最佳发射波束(Beam determination)。更为复杂的是，用户也有天线阵列。这意味着，在波束对准的过程中既要考虑发射波束，也要考虑接收波束。为此，5G标准允许用户对发射波束变换不同的接收波束，并从中选择最佳接收波束，由此产生一对最佳发射—接收波束。如图1所示，用户1和用户2所对应的最佳发射—接收波束对分别为(t4，r3)和(t6，r2)。这个波束对准匹配的扫描过程称为波束管理技术。
实际上，为保证最终得到足够的信号增益，大规模天线阵列所产生的波 束通常需要变得很窄。付出的代价是，基站需要使用大量的窄波束才能保证小区内任意方向上的用户都能得到有效覆盖。在此情况下，遍历扫描全部窄波束来寻找最佳发射—接收波束的策略显得费时费力，与5G所期望的用户体验不符。同时，考虑到用户可能处于移动状态，最佳发射—接收波束会随着用户的位置而发生变化，为了更好地跟踪用户(Beam tracking)，寻找最佳发射—接收波束，需要反复进行遍历扫描过程，不断切换最佳发射—接收波束，为用户提供无缝覆盖，保证通信不中断、不掉线，这无疑增加了波束管理***的复杂程度及通信的实时效果。

通过5G基站的波束天线向目标用户所在的方位角度范围发射N个第二波束，N为大于1的整数；
所述5G基站基于N个第二波束遍历扫描目标用户所在的方位角度范围。
在本申请的示例性实施例中，波束扫描匹配管理分两个阶段进行：
第一阶段、利用NSA架构中的4G基站进行全方位大范围实时覆盖5G用户，通过该4G基站可以实时跟踪覆盖范围内的5G用户，得到用户所在的方位角度范围并反馈给5G基站；
第二阶段、5G基站利用多个窄波束逐一扫描已在第一阶段中被4G基站覆盖的用户方位角度范围。对单个用户而言，尽管此时的扫描波束变窄，但 所需扫描的范围却已缩小，扫描次数便相应减少。此时，5G基站改善了对准每个用户的波束方向的精度，所建立的无线通信连接质量得到提高。由此，实现最佳匹配波束的细扫描。
实施例二
该实施例在实施例一的基础上给出了确定目标用户所在的方位角度范围的方案。
在本申请的示例性实施例中，步骤S101确定目标用户所在的方位角度范围包括：
接收目标用户发送的第一波束测量信息；所述第一波束测量信息为目标用户根据第一基站发射的M个第一波束进行强度测量获得的；
根据所述目标用户的第一波束测量信息，确定所述目标用户所在的方位角度范围。
4G基站依次使用不同指向的波束发射无线信号，该过程被称作波束扫描(Beam sweeping)；与此同时，用户测量不同波束发射出的无线信号(Beam measurement)，并向4G基站报告相关信息(Beam reporting)；基站根据用户报告确定对准该用户的方位角度范围。
在本申请的示例性实施例中，与步骤S101相应的，步骤S102确定第二基站与所述目标用户之间的匹配波束包括：
接收目标用户发送的第二波束测量信息；所述第二波束测量信息为目标用户根据第二基站发射的N个第二波束进行强度测量获得的；
根据所述目标用户的第二波束测量信息，确定所述目标用户对应的最佳发射—接收波束。
本申请实施例中，每个第一波束对应的第二波束的数量可以相同或者不同，例如，可以第一波束A对应3个第二波束，第一波束B对应4个第二波束，或者第一波束C对应4个第二波束，第一波束D也对应4个第二波束，具体的对应关系，依据NSA***的部署。
实施例三
如图3所示，本申请实施例还提供6.一种基于非独立组网NSA***的波束管理方法，其中，所述方法包括：
S201、终端接收第一基站发射的M个第一波束，并对所述M个第一波束进行强度测量，M为大于或者等于1的整数；
S202、向所述第一基站反馈第一波束测量信息，所述第一波束测量信息为所述终端根据第一基站发射的M个第一波束进行强度测量获得的；
S203、终端接收第二基站发射的N个第二波束，并对所述N个第二波束进行强度测量，N为大于1的整数；
S204、向所述第二基站反馈第二波束测量信息，所述第二波束测量信息为所述终端根据第一基站发射的N个第二波束进行强度测量获得的。
在本申请的示例性实施例中，终端都会接收第一基站发射的第一波束，并记录自身对各个第一波束的接收质量。当第一基站第一波束发射完成之后，终端可以比较自身对各第一波束的接收质量，进而从M个第一波束中将质量最好的第一波束作为选择波束。可以理解的是，本实施例中的选择波束可以不只一个，例如除了接收质量最好的波束，还包括还可以选择接收质量次佳的波束等。
在本申请的示例性实施例中，与终端接收第一基站发射的第一波束相似地，接收第二波束的终端测量自身对各个第二波束的接收质量，进而从N个第二波束中将质量最好的第二波束作为匹配波束。
实施例四

实施例六
如图8所示，以4G基站使用120度定向天线为例，则只需3个天线即可完成S1、S2、S3全方位覆盖，所以通过该4G基站可以实时跟踪覆盖范围内的5G用户，得到用户位置信息(位于S3方向上)并反馈给5G基站控制***。
在图8中，在4G基站覆盖大范围跟踪的基础上，5G基站只需继续细化扫描与各用户有关的4个窄波束，比如为用户1扫描波束t1-t4。因此，在图8所示的基于NSA的波束管理过程中，基站只需为每位用户扫描4次，而无需对全部12个波束都进行扫描。
基于NSA***的波束管理方法利用了5G NSA(非独立组网)下4G基站大范围全方向实时覆盖的特性，有效减少5G波束匹配遍历扫描的范围、次数， 减少资源浪费，而且对基站和用户阵列天线数逐渐增多尤为明显，同时为用户提供无缝覆盖，保证通信不中断、不掉线，提高通信质量。
实施例七
