具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本发明的实施例提供一种波束分组扫描方法，该方法应用于多天线系统中，参照图1所示，该方法可以包括以下步骤：
步骤101、获取多天线系统的发射端的每个波束的宽度。
在多天线系统中，发射端有多个天线，这些发射端天线可以通过波束成形的方法，形成一个个波束对准接收端，从而提升接收端的接收增益，同时降低对其他波束的干扰。波束成形是发射端对数据先加权再发送，形成窄的发射波束，将能量对准目标用户，从而提高目标用户的解调信噪比，这对改善小区边缘用户吞吐率特别有效，而且波束成形可以获得阵列增益、分集增益和复用增益。
具体的，可以是通过获取多天线系统中的发射端可以发射的波束的宽度来得到每个波束的宽度，可以发射的波束的宽度主要取决于发射端的能力和功率。
步骤102、根据每个波束的宽度，按照预设规则将一个波束扫描周期分割为至少两个时间段，并设置至少两个时间段中的每个时间段对应的波束的发射方向和数量。
具体的，预设规则可以是预先设置的对发射端在一个波束扫描周期内可以发射的波束的次数和每次发射的波束的数量和方向进行设置的一个规则，并且按照预设规则对波束进行设置之后，一个波束扫描周期内总共发射的所有波束可以完全覆盖整个小区，实现360度全覆盖。
本发明的实施例所提供的波束分组扫描方法，可以获取多天线系统的发射端的每个波束的宽度，之后根据每个波束的宽度，按照预设规则将一个波束扫描周期分割为至少两个时间段，并设置至少两个时间段中的每个 时间段对应的波束的发射方向和数量，这样，可以基于发射端的实际发射能力设置一个波束扫描周期内发射的波束的次数及每次发射的波束的数量和方向，解决了现有的波束扫描方案在一个波束扫描周期内不能一次性扫描整个小区的问题，实现一个波束扫描周期内可以一次性扫描整个小区，提高了资源的利用率；同时，提高了用户和小区的吞吐量。
本发明的实施例提供一种波束分组扫描方法，该方法应用于多天线系统中，参照图2所示，该方法可以包括以下步骤：
步骤201、获取多天线系统的发射端的每个波束的宽度。
步骤202、根据每个波束的宽度，计算得到多天线系统的发射端需要发射的波束的数量为N。
其中，N为正整数。
具体的，因为最终在一个波束扫描周期内发射的所有波束可以实现对整个小区的覆盖，即360度全覆盖，因此，多天线系统中的发射端需要发射的波束的数量可以是360除以每个波束的宽度得到的，如果每个波束的宽度为θ，那么N＝360/θ。
步骤203、按照预设规则将N个波束进行分组。
具体的，对得到的多天线系统中的发射端需要发射的波束进行分组，分组之后每组波束中的所有波束的数量加起来等于发射端需要发射的波束的总数量。
步骤204、获取当前每组波束对应的业务量。
具体的，当前每组波束对应的业务量，即发射端需要进行波束扫描的时刻对应的每组波束中的业务量，这样可以保证得到的每组波束对应的业务量的准确性。波束分组完成后每组波束中的可以发射的波束的数量是固定的，但是每组波束中可以发射的波束的数量可以不相同。
步骤205、根据当前每组波束对应的业务量，将一个波束扫描周期分割 为至少两个时间段。
具体的，可以根据每组波束对应的业务量的大小来划分一个波束扫描周期，并设置划分之后的每个时间段对应的扫描时间，如果某一波束组对应的业务量比较大则可以设置这个组对应的时间段的波束扫描时间较长，如果某一波束组对应的业务量比较小则可以设置这个组对应的时间段的波束扫描时间较短，当然，所有组对应的时间段的波束扫描时间加起来等于一个波束扫描周期。其中，划分得到的波束组的数量与一个波束扫描周期分割成的时间段的数量可以是相同的。
步骤206、设置每个时间段内对应的波束的发射方向和数量。
具体的，每个时间段内的波束的发射方向和数量即可以是与对应的波束组内的波束的发射方向和数量，例如，第一时间段内对应的波束的发射方向和数量可以是第一组波束组中的波束的发射方向和数量。
需要说明的是，本实施例中与其它实施例中相同步骤或概念的解释可以参照其它实施例中的描述，此处不再赘述。
本发明的实施例所提供的波束分组扫描方法，可以获取多天线系统的发射端的每个波束的宽度，之后根据每个波束的宽度，按照预设规则将一个波束扫描周期分割为至少两个时间段，并设置至少两个时间段中的每个时间段对应的波束的发射方向和数量，这样，可以基于发射端的实际发射能力设置一个波束扫描周期内发射的波束的次数及每次发射的波束的数量和方向，解决了现有的波束扫描方案在一个波束扫描周期内不能一次性扫描整个小区的问题，实现一个波束扫描周期内可以一次性扫描整个小区，提高了资源的利用率；同时，提高了用户和小区的吞吐量。
本发明的实施例提供一种波束分组扫描方法，该方法应用于多天线系统中，参照图3所示，该方法可以包括以下步骤：
步骤301、获取多天线系统的发射端的每个波束的宽度。
步骤302、根据每个波束的宽度，计算得到多天线系统的发射端需要发射的波束的数量为N。
其中，N为正整数。
步骤303、将N个波束分割为k组。其中，k<＝N/M。
其中，M为发射端最多能够发射的波束的数量。
发射端最多能够发射的波束的数量可以是由多天线系统的发射端的功率和能力决定的。
步骤304、获取当前每组波束中每个波束对应的用户数和每个波束下每个用户的业务量。
具体的，获取当前每组波束中每个波束对应的用户数和每个波束下每个用户的业务量，可以是通过在发射端需要进行波束扫描的时刻获取每组波束中每个波束对应的用户数和每个波束下每个用户的业务量来实现，此时得到的每个波束对应的用户数和每个波束下每个用户的业务量的信息是最新的，即使有新用户接入或者用户需要重新传输数据等情况，也可以保证用户数和每个用户的业务量的准确性。
步骤305、根据当前每个波束对应的用户数和每个波束下每个用户的业务量，计算得到每组波束对应的业务量。
具体的，每个波束对应的用户数和每个波束下每个用户的业务量，可以计算得到每个波束的业务量，然后将每个波束组中的每个波束的业务量相加得到当前每组波束对应的业务量。
步骤306、根据当前每组波束对应的业务量，计算得到当前N个波束对应的总业务量。
具体的，将当前每组波束对应的业务量相加，即可以得到当前N个波束对应的总业务量。
步骤307、计算当前每组波束对应的业务量在总业务量中的权重。
具体的，计算当前每组波束对应的业务量在N个波束对应的总业务量中所占的比例，得到当前每组波束对应的业务量在总业务量中的权重。
步骤308、根据当前每组波束对应的业务量在总业务量中的权重和波束扫描周期，计算每组波束需要的发射时间。
具体的，可以用每组波束对应的业务量在总业务量中的权重乘以波束扫描周期，得到对应的时间段(对应的波束组)的扫描时间(需要的发射时间)。例如，假设波束扫描周期为T，假设N个波束被分为三组，第一组波束对应的业务量为S1，第二组波束对应的的业务量为S2，第三组波束对应的的业务量为S3。根据业务量比例来进行扫描时间分配，比如，第一组波束的扫描时间为t1＝ceil(T*(S1/S1+S2+S3))，第二组波束的扫描时间为t2＝ceil(T*(S2/S1+S2+S3))，第三组波束的扫描时间为t3＝T-t1-t2。当然，这里如果t3计算出来的时间为0或负值，那需要重新调整下三个组的扫描时间，保证每个波束组发送一次广播，也就是保证整个小区的覆盖。
步骤309、基于每组波束需要的发射时间，将一个波束扫描周期分割为至少两个时间段。
步骤310、分别设置每组波束中波束的数量为Ai。
其中，Ai<＝M，；每个波束的宽度乘以(A1+A2+A3+…Ai+…Ak)的值等于360。
步骤311、设置第一组波束中第一个波束的初始发射方向，并根据初始发射方向和每个波束的宽度，确定每个时间段内对应的波束的发射方向。
其中，假设多天线系统的发射端，波束成型的每个波束宽度为15度，为了使发射端覆盖整个区域，发射端需发射360/15＝24个波束才能覆盖整个区域。由于受限于发射端的能力和功率，发射端在每个时刻只能形成M＝8个波束宽度为15的波束。为了使发射端能够覆盖整个区域，发射端可以通过时分的方式，在不同时刻形成不同方向的波束。比如，可以将需要发射 的波束按照号码进行编码(即包括1、2、3…24)：在时刻T1，发射端可以形成对应编号为{1、4、7、10、13、16、19、22}这8个波束，称为第一组波束；在T2时刻，发射端可以形成{2、5、8、11、14、17、20、23}这8个波束，称为第二组波束；在T3时刻，可以形成{3、6、9、12、15、18、21、24}这8个波束，称为第三组波束。这样，可以将24个波束分成三个波束组，每个组的波束固定。当然，此处只是举例说明波束的一种分组方法和每组中波束的数量，并没有限定只能是如此。
需要说明的是，本实施例中与其它实施例中相同步骤或概念的解释可以参照其它实施例中的描述，此处不再赘述。
