Description

多通道波束赋形方法、装置及存储介质
本申请要求于2018年09月25日提交中国专利局、申请号为201811117083.7、申请名称为《多通道波束赋形方法、装置及存储介质》的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及天线技术，尤其涉及一种多通道波束赋形方法、装置及存储介质。
背景技术
在多通道场景下，同极化通道间信号相干会导致波束赋形，若波束赋形不加以控制，会影响网络覆盖和网络容量。而实际波束赋形效果同相位强相关，一般需要进行相位校准来达成预期的波束赋形效果，即得到预期的方向图。
现有技术通过对发通道进行相位校准，基于机器学习并利用现网反馈选择最优相位，获得匹配现网的波束，在保障网络覆盖的同时获得容量增益。
但上述方法中，相位校准往往需要付出较大代价来实现，例如，在普通多天线加射频模块场景下，相位校准只能校准到射频口，无法校准到天线口，这样，射频口至天线口之间的路径就无法进行相位校准，导致方向图不确定；又例如，在无校准回路的射频模块上进行相位校准时，需构建校准回路，这使得相位校准更加复杂。
发明内容

实际应用中，当需要对待发送的下行信号进行多通道波束赋形时，波束赋形系统20通过天线射频模块21生成待发射信号，并通过波束赋形模块22执行S301进行正负极化的下行正交波束配对。其中，目标下行正极化波束和目标下行负极化波束二者进行正负极化的下行波束配对，且二者正交。
S302、根据目标下行正极化波束及目标下行负极化波束，得到目标下行信号。
例如，波束赋形系统20通过波束赋形模块22执行S302，得到目标下行信号。
通过上述正负极化的下行波束配对，达到正负极化间下行波束正交，合成波束就同普通天线覆盖基本一致，可以保证网络覆盖不受损。
本申请实施例，首先根据预设的M个权值集合，确定目标下行正极化波束和目标下行负极化波束，之后，根据目标下行正极化波束及目标下行负极化波束，得到目标下行信号，其中，权值集合包括相位权值集合和幅度权值集合，不同权值集合所包含的幅度权值集合相同，不同权值集合所包含的相位权值集合不同，相位权值集合中相位权值的个数与幅度权值集合中幅度权值的个数均是根据多通道的通道个数确定的，M为大于0的偶数。通过上述正负极化的下行波束配对，达到正负极化间下行波束正交，以在无相位校准情况下，保证多通道场景下的覆盖网络。
在上述实施例的基础上，一种可能的实现方式中，如图4所示，S301、根据预设的M 个权值集合，确定目标下行正极化波束和目标下行负极化波束，可以包括以下子步骤：
S401、根据预设的M个权值集合，对待发射信号进行波束赋形，得到M个波束。
其中，预设的M个权值集合包括N个正极化权值集合和N个负极化权值集合。正极化权值集合包括正极化相位权值集合，每个正极化权值集合对应一个正极化波束。负极化权值集合包括负极化相位权值集合，每个负极化权值集合对应一个负极化波束。其中，M等于N的2倍。
S402、分别计算M个波束对应的所有用户的专用物理控制信道(Dedicated Physical Control Channel，DPCCH)发射功率之和。
其中，正极化波束对应的所有用户的DPCCH发射功率之和为正极化DPCCH发射功率之和，负极化波束对应的所有用户的DPCCH发射功率之和为负极化DPCCH发射功率之和。
S403、确定N个正极化DPCCH发射功率之和中最小的正极化DPCCH发射功率之和对应的波束为目标下行正极化波束。

以下通过具体实例说明上述实施例中的多通道波束赋形方法。
为方便描述，采用2列4端口天线举例说明，其中，2列4端口天线的示意图如图5所示。
将360度圆周等分成n份(为方便描述，n＝8)，给出0，45，90，135，180，225，270，315这8个相位值。
其中，天线的方向图和相位强相关，在幅度不变情况下，方向图由相位唯一决定。在单个通道上，射频拉远单元(Remote Radio Unit，RRU)，馈线，跳线，天线等都会引入相位。其中，RRU是有源器件，相位在时间维度上变化。其他都是无源器件，在时间维度上较为稳定。因此，在短时间内(取决于RRU的相位漂移速度)，天线方向图是平稳态。可以通过基带叠加额外相位，改变极化内相位差，达到调整方向图目的。
在一定时间周期(比如1小时)内，分别对正负极化之间相位差进行调整，调整值为0，45，90，135，180，225，270，315这8个相位值，然后每个方向图进行所有用户的DPCCH发射功率测量，根据所有用户的DPCCH发射功率之和进行排序，如表1所示。
参考表1，正极化相位差45度时，其DPCCH发射功率之和最小，因此，目标下行正极化波束就选择该相位差，进一步，需要再选择负极化相位差同正极化进行配对。
可以看出：负极化相位差在90度时，DPCCH发射功率之和最小。可以等效认为在相同扇区下，达到DPCCH发射功率之和都最小时的方向图基本相当。因此，在负极化中，选择相位差：(90+180)＝270，可以达到和相位差90度最为正交，同时和正极化相位差45度方向图最为正交，如此就达到了下行正负极化间波束配对目的(正极化选择波束2，负极化选择波束7)。配对后，正负极化方向图如图6A和图6B所示。图6A为正负极化完全正交互补，实际应用中正负极化可存在一定度数的偏差。该偏差与等分360度圆周相 关，如等分成8份，最大偏差为22.5度，参考图6B。如需偏差更小，可以将360度圆周等分成更多份。在图6A和图6B中，实线为正极化方向图，虚线为负极化方向图。

另一种可能的实现方式中，如图7所示，S301、根据预设的M个权值集合，确定目标下行正极化波束和目标下行负极化波束，可以包括以下子步骤：
S701、周期性扫描上行波束。
S702、确定每一周期内上行波束上所有用户的能量值。
该能量值包括上行正极化能量值和上行负极化能量值。
S703、根据能量值及正负极化正交需求，确定目标上行正极化波束和目标上行负极化波束。
S704、根据目标上行正极化波束，确定目标下行正极化波束。
S705、根据目标上行负极化波束，确定目标下行负极化波束。
其中，上行波束只用于测量上行能量值(Eb值)，通过周期性扫描上行波束，得到周期内上行波束上所有用户的能量值，进而根据能量值及正负极化正交需求，确定目标上行正极化波束和目标上行负极化波束；之后，和下行波束进行配对，即可确定下行波束(包括目标下行正极化波束和目标下行负极化波束)，而不需要频繁进行下行波束DPCCH测量，影响下行覆盖。
该实施例通过上下行波束配对进行波束选择，相比现有技术，无需依赖相位校准即可实现下行波束的选择。
在一些实施例中，S703、根据能量值及正负极化正交需求，确定目标上行正极化波束和目标上行负极化波束，可以包括：确定N个上行正极化能量值中最大的上行正极化能量值对应的波束为目标上行正极化波束；确定N个上行负极化能量值中最大的上行负极化能量值对应的波束为第二波束；根据目标上行正极化波束、正负极化正交需求及第二波束，确定目标上行负极化波束。
可以理解，上下行波束配对，对上行波束根据某测量值(例如Eb值)进行排序，对下行波束根据某测量值(例如DPCCH发射功率之和)进行排序；然后，根据上下行分别排序的结果，进行上下行两两波束组合配对。
仍以将360度圆周等分成n份(为方便描述，n＝8)，给出0，45，90，135，180，225，270，315这8个相位值，为例进行说明。8个相位值相当于预置了8个波束。
上行波束只用于测量，每个极化分别在8个波束中做动态扫描，如图8所示。其中，测量周期2s，统计2s内该上行波束上所有用户的能量值，例如Eb值，一共32s完成正负极化所有上行波束测量。然后，进行上下行波束配对。
假设当前测量到上行波束上所有用户的Eb值和下行DPCCH发射功率之和为：
表2
Figure PCTCN2019107626-appb-000002
表3
Figure PCTCN2019107626-appb-000003
参考表2和表3，目标上行正极化波束选择波束5，负极化由于波束4的Eb值最大，而由于要达到正负极化正交覆盖，因此，负极化选择和波束4正交波束，故选择波束4相位差再增加180度相位差对应的波束：mod(135+180,360)＝315，即目标上行负极化波束选择波束8。
由此完成上下波束配对，见表4。
表4
  目标上行波束 目标下行波束
正极化 波束5 波束2
负极化 波束8 波束7
第一次上下行波束配对完成后，后续根据上行波束变化选择下行波束。该处等效认为上下行通道的相位差值为稳定值。因此，结合表4做以下说明：
当前正极化上行波束5(相位差180)对应下行波束2(相位差45)。如果其他周期扫描正极化上行选择波束3(相位差90度)，那么认为相位偏移-90度，同步认为下行相位偏移-90度，故下行正极化应该选择：mod(45+(-90,360)＝315度，选择下行波束8。按照相同方法更新负极化下行波束。
图9为本申请又一实施例提供的多通道波束赋形方法的流程图。如图9所示，本实施例中的多通道波束赋形方法可以包括以下步骤：
S901、周期性扫描上行波束。
S902、确定每一周期内上行波束上所有用户的能量值。
该能量值包括上行正极化能量值和上行负极化能量值。
S903、根据能量值及正负极化正交需求，确定目标上行正极化波束和目标上行负极化波束。
S904、根据目标上行正极化波束，确定目标下行正极化波束。
S905、根据目标上行负极化波束，确定目标下行负极化波束。
其中，S901～S905分别与S701～S705相同，此处不再赘述。
S906、根据用户调度的优先级，通过波束码字复用动态选择用户调度。
其中，波束码字复用用于表示相同小区下正负极化波束采用不同码字。
可选地，该步骤可以包括：根据用户调度的优先级，确定当前处于最高优先级的第一待调度用户；计算目标上行正极化波束上接收到的第一待调度用户对应的能量值为第一能量值；计算目标上行负极化波束上接收到的第一待调度用户对应的能量值为第二能量值；在第一能量值与第二能量值之差大于或等于第一预设值时，确定当前处于次高优先级的第二待调度用户；计算目标上行正极化波束上接收到的第二待调度用户对应的能量值为第三能量值；计算目标上行负极化波束上接收到的第二待调度用户对应的能量值为第四能量值；在第三能量值与第四能量值之差小于或等于第二预设值时，确定在目标下行正极化波束及目标下行负极化波束上，同时调度第一待调度用户和第二待调度用户。
S907、根据目标下行正极化波束及目标下行负极化波束，得到目标下行信号。
该步骤同S302。
该实施例，在完成下行正交波束配对，上下行波束配对后，对用户进行码字复用动态调度。具体地：按照小区正常调度排序，选择当前待调度用户。确定当前的高优先级待调度用户(即第一待调度用户)后，计算上行正负极化波束接收到的该用户的Eb值，如果正负极化Eb值相差超过xdB(例如10dB)，则再在小区正常调度排序中选择一个用户(即第二待调度用户)，满足上行正负极化Eb值小于-xdB(例如10dB)。此时，可以认为两个待调度用户处在两个正交波束上，可以同时调度这两个用户，参考图10。
若不满足上述条件，则只调度第一待调度用户。
上述实施例通过波束码字复用动态选择待调度用户来提升容量增益。相比机器学习，波束码字复用可获得20％～30％容量增益，从而在保证网络覆盖的同时，提升容量增益。
仿真实验
设定第一预设值为10dB，可进行波束码字复用调度的占比为61.9％。在Volcano传模下，通过3D电子地图仿真，容量增益约20％～30％。
通过上述多通道波形赋形方法，一方面，保证网络覆盖；另一方面，提升容量增益。因此，可提高多通道场景解决方案竞争力。
