Description

分配时频资源的方法和装置
本申请要求于2018年6月20日提交的申请号为201810636394.8、发明名称为“分配时频资源的方法和装置”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
本申请涉及通信技术领域，特别涉及一种分配时频资源的方法和装置。
背景技术
随着通信技术的发展，4G用户设备越来越多，对网络的覆盖和质量要求也越来越高，为了解决深度网络覆盖并提升网络质量，在不新增设备(如基站等)的情况下，且在有限的时频资源下，利用软劈裂技术，来改善网络覆盖范围，且提升网络容量。软劈裂技术是指对基站的扇区进行适当劈裂，使得基站的扇区数量增加，在增加的扇区覆盖范围内分配更多的载波，载波数量的增加对应着用户设备数量的增加，可以实现网络扩容，且劈裂后的扇区波束更窄，覆盖范围更大。
相关技术中，软劈裂技术一般是通过调整天线的相位权值和幅度，将传统单基站3扇区转变成6小区。软劈裂技术可以包括同频软劈裂，同频软劈裂指将一个小区劈裂成两个覆盖对称的小区，且劈裂后的两个小区中的用户设备(User equipment，UE)可以使用相同的时频资源，也就是实现两个小区时频资源的空分复用，例如，F频段(频率范围为20M)小区可以同频软劈裂为两个相邻的同频小区，劈裂后的两个相邻的同频小区可以使用的频段变为20+20M。在同频软劈裂后，基站分别为两个小区调度时频资源。
在实现本申请的过程中，发明人发现相关技术至少存在以下问题：
劈裂后的两个小区的覆盖虽然对称，但是两个小区内的UE分布不一定对称，有可能出现一个小区UE多，另一个小区UE少的情况(例如，小区1有10个UE，小区2有1个UE)，这样，虽然空分了两份时频资源，但是基站是分别为两个小区调度时频资源，导致UE少的小区的时频资源并没有得到有效的利用。
发明内容
为了解决相关技术的问题，本发明实施例提供了一种分配时频资源的方法和装置。所述技术方案如下：
第一方面，提供了一种分配时频资源的方法，所述方法包括：
获取待分配用户设备UE的上行参考信号，其中，所述上行参考信号包括上行信道探测参考信号SRS和/或特定参考信号DMRS；根据所述上行参考信号，对第一预设数目个波束组成的第二预设数目个正交波束组中每个波束进行测量，确定所述每个波束的电平；根据所述每个波束的电平，确定所述待分配UE在所述第二预设数目个正交波束组中的波束属性；根据所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，为所述待分配UE分配时频资源，其中，所述已分配 UE使用同一时频资源，所述同一时频资源为同一时频资源块RB或同一时频资源块组RBG。
其中，正交波束组是指包括的多个波束之间相互不受干扰，或者多个波束之间的干扰均小于一定阈值，不会影响数据的正常发送和接收，第一预设数目个波束可以由技术人员基于基站的天线情况配置，通过调整基站天线的加权系数和幅值等，可以将第一预设数目个波束组成第二预设数目个正交波束组，例如，一共有M个波束，每次调整基站天线的加权系数和幅值，可以将这M个波束，变成另外的M个波束，且彼此正交，通过(N-1)次调整，会得到N个正交的波束组，第二预设数目为N。电平指波束的等效功率。
本发明实施例所示的方案，基站有数据要传输给劈裂后的小区中的UE，或者，劈裂后的小区中的UE有数据传输给基站，基站需要给UE分配用户传输数据的时频资源，基站在分配时频资源时，可以获取待分配UE的上行参考信号，上行参考信号中包括上行信道探测参考信号(Sounding Reference Signal，SRS)和/或特定参考信号(Demodulation Reference Signal，DMRS)，SRS一般是UE周期性传输给基站，用于基站进行上行信道估计，一般是在一个子帧的最后一个符号中进行传输，DMRS一般是传输数据时，仅在为特定UE的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输而分配的资源块(Resource Block，RB)中进行传输。
如果基站已经接收到当前周期内待分配UE发送的SRS，则可以获取当前周期内的SRS，如果基站未接收到当前周期内待分配UE发送的SRS，则可以获取上一个周期待分配UE发送的SRS。并且基站可以获取上一次待分配UE传输数据时的DMRS。
然后基站可以根据获取到的上行参考信号，使用上行参考信号，对每个正交波束组中的任一波束进行测量，得到任一波束的电平。
基站在确定每个正交波束组中的各波束的电平后，可以基于各波束的电平，确定待分配UE在每个正交波束组中的波束属性。最后基站在确定待分配UE在每个正交波束组中的波束属性后，基站可以获取同一时频资源上的已分配UE(与待分配UE属于劈裂后的同一小区或者分别属于劈裂后的两个小区)，然后获取已分配UE在第二预设数目个波束组上每个波束组的波束属性(确定方法与前面确定待分配UE的方法相同，此处不再赘述)。然后根据待分配UE的波束属性和已分配UE的波束属性，为待分配UE分配时频资源。
在一种可能的实施方式中，所述根据所述上行参考信号，对第一预设数目个波束组成的第二预设数目个正交波束组中每个波束进行测量，确定所述每个波束的电平，包括：根据所述上行参考信号，对第一预设数目个波束组成的第二预设数目个正交波束组中每个波束进行测量，确定所述每个波束的等效信道响应；根据所述每个波束的等效信道响应，确定所述每个波束的电平。
本发明实施例所示的方案，对于第二预设数目个正交波束组中任一正交波束组，基站可以确定该正交波束组中每个波束的等效信道响应，这样，就可以得到每个正交波束组中各波束的等效信道响应，根据每个正交波束组中各波束的等效信道响应，确定出每个波束的电平。
在一种可能的实施方式中，所述根据所述每个波束的电平，确定所述待分配UE在所述第二预设数目个正交波束组中的波束属性，包括：对于每个正交波束组，如果所述正交波束组中存在目标波束满足预设条件，则确定所述待分配UE在所述正交波束组中的波束属性为所述目标波束，如果所述正交波束组中不存在波束满足所述预设条件，则确定所述待分配UE在所述正交波束组中的波束属性为联合属性；其中，所述预设条件为所述目标波束的电平与 所述正交波束组中除所述目标波束之外的其它波束的电平的差值均大于或等于预设数值。
其中，预设条件可以预设，并且存储至基站中，预设条件为目标波束的电平与正交波束组中除目标波束之外的其它波束的电平的差值均大于预设数值，目标波束为一个或多个，预设数值可以预设，并且存储至基站中，用于衡量波束之间的相关性。
本发明实施例所示的方案，对于任一正交波束组，基站可以比较该正交波束组中，每个波束的电平，如果该正交波束组中的目标波束的电平与该正交波束组中除目标波束之外的其它波束的电平的差值，均大于或等于预设数值，则确定待分配UE在该正交波束组中的波束属性为目标波束。
例如，待分配UE在某个正交波束组中，电平最高的波束x(目标波束)的电平与其他波束的电平之差大于或等于预设数值，待分配UE的波束属性为波束x，或者电平较高的多个波束x、y的电平与其他任一波束的电平的差值大于或等于一定预设数值，则判断待分配UE的波束属性为波束x、波束y。如果该正交波束组中不存在波束满足上述预设条件，则可以确定待分配UE在该正交波束组中的波束属性为联合属性。
在一种可能的实施方式中，为所述待分配UE和所述已分配UE分配的时频资源用于下行传输；
所述根据所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，为所述待分配UE分配时频资源，包括：确定所述待分配UE的传输模式和已分配UE的传输模式；根据所述待分配UE的传输模式和已分配UE的传输模式、所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，为所述待分配UE分配时频资源。
其中，基站向UE下行传输数据时，传输模式一般有多入多出(Multiple-Input Multiple-Output，MIMO)传输模式、波束赋形(Beam Forming，BF)传输模式、发射分集等传输模式。在本发明实施例中，提到的传输模式是下行传输模式，一般是基于小区特定参考信号(Cell Reference Signal，CRS)的MIMO传输模式和BF传输模式。
本发明实施例所示的方案，基站可以基于用于解调的参考信号来判断UE的传输模式，如果是基于CRS进行解调，则确定UE是基于CRS的MIMO传输模式，如果是基于UE的DMRS进行解调，则确定UE是BF传输模式。基于这种原则，基站可以确定待分配UE和已分配UE的传输模式，然后根据待分配UE的传输模式和已分配UE的传输模式、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE的波束属性，为待分配UE分配时频资源。
在一种可能的实施方式中，所述根据所述待分配UE的传输模式和已分配UE的传输模式、所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，为所述待分配UE分配时频资源，包括：根据所述待分配UE的传输模式和已分配UE的传输模式、所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，如果所述待分配UE和已分配UE满足正交匹配条件，则在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配时频资源。
其中，正交匹配条件是指在同一时频资源上传输下行数据时，相互不会干扰的两个UE 所满足的条件。
本发明实施例所示的方案，基站可以根据待分配UE的传输模式和已分配UE的传输模式、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE在第二预设数目个正交波束组中的波束属性，确定待分配UE和已分配UE是否满足正交匹配条件，如果待分配UE与已分配UE满足正交匹配条件，说明待分配UE与已分配UE中任一UE的相关性比较小，不会互相影响，可以在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。另外，如果待分配UE与已分配UE不满足正交匹配条件(与已分配UE中某个UE不满足正交匹配条件)，说明待分配UE与已分配UE中该UE的相关性比较大，会互相影响，有可能会影响UE接收解调数据，所以不能在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。
在一种可能的实施方式中，所述根据所述待分配UE的传输模式和已分配UE的传输模式、所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，如果所述待分配UE和已分配UE满足正交匹配条件，则在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配时频资源，包括：如果所述已分配UE和所述待分配UE中存在至少一个UE的传输模式为基于小区特定参考信号CRS解调的多入多出MIMO传输模式，则获取所述待分配UE所属小区的物理小区标识PCI和所述已分配UE所属小区的PCI；根据所述待分配UE在所述第二预设数目个正交波束组中的波束属性、已分配UE在所述第二预设数目个正交波束组中的波束属性、所述待分配UE所属小区的PCI以及所述已分配UE所属小区的PCI，如果所述待分配UE和已分配UE满足正交匹配条件，则在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配时频资源。
本发明实施例所示的方案，UE在刚接入LTE网络时，基站会记录UE所属小区的物理小区标识(Physical cell identification，PCI)，所以基站可以从预先记录PCI的存储位置，获取到待分配UE和已分配UE所属小区的PCI。基站确定出待分配UE与已分配UE的传输模式后，可以判断他们中是否存在至少一个UE的传输模式为基于CRS的MIMO传输模式，如果存在，则获取待分配UE所属小区的PCI、已分配UE所属小区的PCI，然后根据获取到的PCI、以及待分配UE在第二预设数目个正交波束组中的波束属性、已分配UE在第二预设数目个正交波束组中的波束属性，来确定待分配UE与已分配UE是否满足正交匹配条件。如果满足正交匹配条件，则可以在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。
在一种可能的实施方式中，所述根据所述待分配UE在所述第二预设数目个正交波束组中的波束属性、已分配UE在所述第二预设数目个正交波束组中的波束属性、所述待分配UE所属小区的PCI以及所述已分配UE所属小区的PCI，如果所述待分配UE和已分配UE满足正交匹配条件，则在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配时频资源，包括：如果所述待分配UE的传输模式为所述MIMO传输模式，且所述待分配UE所属小区的PCI与所述已分配UE中传输模式为所述MIMO传输模式的UE所属小区的PCI不相同，且所述待分配UE所属小区的PCI与所述已分配UE中传输模式为BF传输模式的UE所属小区的PCI不相同，且对于所述已分配UE中第一UE，在所述第二个预设数目个正交波束组中存在至少一个正交波束组，所述待分配UE的波束属性和所述第一UE 的波束属性均不为联合属性，且所述待分配UE的波束属性和所述第一UE的波束属性完全不相同，则所述待分配UE和已分配UE满足正交匹配条件，在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配时频资源，其中，所述第一UE为所述已分配UE中任一UE；如果所述待分配UE的传输模式为BF传输模式，且所述待分配UE所属小区的PCI与所述已分配UE中传输模式为所述MIMO传输模式的UE所属小区的PCI不相同，且对于所述已分配UE中第二UE，在所述第二个预设数目个正交波束组中存在至少一个正交波束组，所述待分配UE的波束属性和所述第二UE的波束属性均不为联合属性，且所述待分配UE的波束属性和所述已分配UE的波束属性完全不相同，则所述待分配UE和所述已分配UE满足正交匹配条件，在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配时频资源，其中，所述第二UE为所述已分配UE中任一UE。
本发明实施例所示的方案，如果待分配UE的传输模式为基于CRS的MIMO传输模式，则基站可以确定已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI，如果待分配UE所属小区的PCI与已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI不相同，则可以确定已分配UE中传输模式为BF传输模式的UE所属小区的PCI，如果确定待分配UE所属小区的PCI与已分配UE中传输模式为BF传输模式的UE所属小区的PCI不相同(也就是说待分配UE的传输模式为基于CRS的MIMO传输模式，已分配的UE中不存在与待分配UE所属小区的PCI相同的UE)，则可以将待分配UE的波束属性与已分配UE中任一UE(即第一UE)的波束属性进行匹配。匹配原则可以是：对于第一UE，判断在第二预设数目个正交波束组中是否存在一个正交波束组，判断在第二预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和已分配UE中第一UE的波束属性均不为联合属性，且他们的波束属性完全不相同，可以确定待分配UE和已分配UE中第一UE满足正交匹配条件。这样，可以确定出待分配UE与已分配UE中任一UE是否满足正交匹配条件。如果待分配UE与已分配UE中任一UE都满足正交匹配条件，则确定待分配UE与已分配UE满足正交匹配条件。可以在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。如果待分配UE的传输模式为BF传输模式，则基站可以确定已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI，如果待分配UE所属小区的PCI与已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI不相同，则可以将待分配UE的波束属性与已分配UE中任一UE(即第二UE)的波束属性进行匹配。匹配原则可以是：对于待分配UE与已分配UE中任一UE，判断在第二预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和已分配UE中第二UE的波束属性均不为联合属性，且他们的波束属性完全不相同，可以确定待分配UE和已分配UE中第二UE满足正交匹配条件。这样，可以确定出待分配UE与已分配UE中任一UE是否满足正交匹配条件。如果待分配UE与已分配UE中任一UE都满足正交匹配条件，则确定待分配UE与已分配UE满足正交匹配条件。可以在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。
在一种可能的实施方式中，所述根据所述待分配UE的传输模式和已分配UE的传输模式、所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，如果所述待分配UE和已分配UE满足正交匹配条件，则在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配 时频资源，包括：如果所述待分配UE和所述已分配UE的传输模式均为BF传输模式，且对于所述已分配UE中第三UE，在所述第二个预设数目个正交波束组中存在至少一个正交波束组，所述待分配UE的波束属性和所述第三UE的波束属性均不为联合属性，且所述待分配UE的波束属性和所述第三UE的波束属性完全不相同，则所述待分配UE和已分配UE满足正交匹配条件，在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配时频资源，其中，所述第三UE为所述已分配UE中任一UE。
本发明实施例所示的方案，基站确定出待分配UE与已分配UE的传输模式后，可以判断它们的传输模式是否相同，如果待分配UE和已分配UE的传输模式均为BF传输模式，则可以将待分配UE的波束属性与已分配UE中任一UE(即第三UE)的波束属性进行匹配。匹配原则可以是：对于待分配UE与已分配UE中任一UE，判断在第二预设数目个正交波束组中是否存在一个正交波束组，待分配UE的波束属性和已分配UE中第三UE的波束属性均不为联合属性，且波束属性完全不相同，可以确定待分配UE和已分配UE中第三UE满足正交匹配条件。这样，可以确定出待分配UE与已分配UE中任一UE是否满足正交匹配条件。
如果待分配UE与已分配UE中任一UE都满足正交匹配条件，则确定待分配UE与已分配UE满足正交匹配条件。可以在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。
在一种可能的实施方式中，为所述待分配UE和所述已分配UE分配的时频资源用于上行传输；所述根据所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，为所述待分配UE分配时频资源，包括：根据所述待分配UE在所述第二预设数目个正交波束组中的波束属性和已分配UE在所述第二预设数目个正交波束组中的波束属性，如果所述待分配UE和已分配UE满足正交匹配条件，则在为所述已分配UE分配的时频资源所属的同一时频资源中，为所述待分配UE分配时频资源。
本发明实施例所示的方案，基站在确定待分配UE在每个正交波束组中的波束属性后，基站可以确定同一时频资源上已分配UE(与待分配UE属于劈裂后的同一小区或者分别属于劈裂后的两个小区)，然后获取已分配UE在第二数目个正交波束组中每个波束组的波束属性，根据待分配UE的波束属性和已分配UE的波束属性，确定待分配UE与已分配UE是否满足正交匹配条件，如果满足正交匹配条件，可以在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。

本发明实施例所示的方案，UE在刚接入LTE网络时，基站会记录UE所属小区的PCI， 所以基站可以从预先记录PCI的存储位置，获取到待分配UE和已分配UE所属小区的PCI。
基站在确定待分配UE在每个正交波束组中的波束属性后，基站可以确定同一时频资源上已分配UE(与待分配UE属于劈裂后的同一小区或者分别属于劈裂后的两个小区)，然后获取已分配UE在第二数目个正交波束组中每个波束组的波束属性。然后基站可以根据待分配UE所属小区的PCI和已分配UE所属小区的PCI、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE在第二预设数目个正交波束组中的波束属性，确定待分配UE和已分配UE是否满足正交匹配条件，如果满足正交匹配条件，可以在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
为了便于对本发明实施例的理解，下面首先介绍本发明实施例涉及的系统架构以及所涉及到名词的概念：
本发明实施例可以适用于长期演进技术(Long Term Evolution，LTE)中，在LTE中，4G用户设备越来越多，对网络的覆盖和质量要求也越来越高，为了解决深度网络覆盖并提升网络质量，在不新增设备(如基站等)的情况下，且在有限的时频资源下，利用软劈裂技术，来改善网络覆盖范围，且提升网络容量。LTE的基站覆盖有三个小区，每个小区覆盖120度的区域，在使用软劈裂技术将一个120度的小区劈裂成两个同频小区后，业务量分布会影响扩容效果，例如，劈裂前小区资源块(Resource Block，RB)负载90％，平均10个UE，每个用户平均可以使用9RB，一共需要100个RB，劈裂后左小区9个UE，右小区1个UE，由于劈裂后的小区的交叠区联合调度RB会有很多，小区频谱效率会降低，大致相当于原来负载的70％～80％，这样，左小区9个UE需要的RB数目为9*9/(70％)＝115，即使左小区负载达到100％，也不够9个UE使用，而右小区1个UE需要的RB数目为1*9/(70％)＝13，右小区的时频资源没有得到有效的利用，所以就需要提供一种有效使用右小区的时频资源的方法。
UE：也叫用户设备、终端设备。其中，终端设备也可以称为接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用 户代理或用户装置。终端设备可以是WLAN中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统。
基站：实现无线通信覆盖并通过至少一个小区为UE提供服务，可选择性支持全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、未来的第五代(5th Generation，5G)系统或新无线(New Radio，NR)等。如图1所示，基站和UE之间可以进行通信。
本发明实施例提供了一种分配时频资源的方法，该方法的执行主体可以是基站。
图2示出了本发明实施例中基站的结构框图，该基站至少可以包括接收器201、处理器202、存储器203和发射器204。其中，接收器201可以用于实现数据的接收，具体可以用于UE的数据的接收，发射器204可以用于数据的发送，具体可以用于UE的数据的发送，存储器203可以用于存储软件程序以及模块，处理器202通过运行存储在存储器203中的软件程序以及模块，从而执行各种功能应用以及数据处理。存储器203主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序等；存储数据区可存储根据基站的使用所创建的数据等。此外，存储器203可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。相应地，存储器203还可以包括存储器控制器，以提供处理器202、接收器201和发射器204对存储器203的访问。处理器202是基站的控制中心，利用各种接口和线路连接整个基站的各个部分，通过运行或执行存储在存储器203内的软件程序和/或模块，以及调用存储在存储器203内的数据，执行基站的各种功能和处理数据，从而对基站进行整体监控。
可选的，处理器202可包括一个或多个处理核心；优选的，处理器202可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器202中。
本发明实施例以基站向UE发送数据为例进行方案的说明，如图3所示，该方案的处理过程可以如下：
步骤301，获取待分配UE的上行参考信号。
其中，UE指劈裂后的两个同频小区中的UE，当前还未分配用于传输数据的时频资源的UE，上行参考信号中包括SRS和/或DMRS。SRS一般是UE周期性传输给基站，用于基站 进行上行信道估计，一般是在一个子帧的最后一个符号中进行传输。DMRS一般是是传输数据时，仅在为特定UE的PDSCH传输而分配的RB中进行传输。
在实施中，在基站接收到核心网侧要发往UE(后续该UE可以称为是待分配UE)的数据时，如果基站已经接收到当前周期内待分配UE发送的SRS，则可以获取当前周期内的SRS，如果基站未接收到当前周期内待分配UE发送的SRS，则可以获取上一个周期待分配UE发送的SRS。和/或基站可以获取上一次UE发送数据时的DMRS。
可选的，在基站同时接收到核心网侧要发送往多个UE的数据时，还会先判断多个UE中优先级最高的UE，一般是基于要传输的数据类型，来判断UE的优先级，如电话语音数据的优先级最高、其次是短消息、再次之是视频数据等，将优先级最高的UE，确定为待分配UE。
需要说明的是，在SRS丢失时，可以仅使用DMRS，在DMRS丢失时，可以仅使用SRS，在同时存在SRS和DMRS时，可以同时使用SRS和DMRS。
步骤302，根据上行参考信号，对第一预设数目个波束组成的第二预设数目个正交波束组中每个波束进行测量，确定每个波束的电平。
其中，正交波束组是指包括的多个波束之间相互不受干扰，或者多个波束之间的干扰均小于一定阈值，不会影响数据的正常发送和接收，第一预设数目个波束可以由技术人员基于基站的天线情况配置，通过调整基站天线的加权系数和幅值等，可以将第一预设数目个波束组成第二预设数目个正交波束组，例如，一共有M个波束，每次调整基站天线的加权系数和幅值，可以将这M个波束，变成另外的M个波束，且彼此正交，通过(N-1)次调整，会得到N个正交的波束组，第二预设数目为N。电平指波束的等效功率。
在实施中，基站在获取到待分配UE的上行参考信号后，可以获取第一预设数目个波束组成的第二预设数目个正交波束组，然后分别使用该上行参考信号，对每个正交波束组中的任一波束进行测量，得到任一波束的电平。
可选的，可以先确定每个波束的等效信道响应，基于等效信道响应，确定每个波束的电平，相应的步骤302的处理可以如下：
根据UE的上行参考信号，对第一预设数目个波束组成的第二预设数目个正交波束组中每个波束进行测量，确定每个波束的等效信道响应；根据每个波束的等效信道响应，确定每个波束的电平。
在实施中，假如基站有P个发送接收物理通道，每个正交波束组中M个波束，M个波束在覆盖上可以达到互补的效果，对于第二预设数目个正交波束组中任一正交波束组，可以按照以下方式计算出等效信道响应：

表示通过加权处理后得到的每个波束的等效信道响应。
这样，按照上述方式，可以计算出第二预设数目个正交波束组中每个正交波束组中每个波束的等效信道响应。
然后基站可以按照以下公式计算每个波束的等效功率：

在式(2)中，

基站确定出每个波束的等效功率后，可以将每个波束的等效功率，分别确定为每个波束的电平。
需要说明的是，此处是以上行参考信号为SRS为例进行说明，如果上行参考信号为DMRS，可以将
Figure PCTCN2019088613-appb-000009
替换成获取到的DMRS，如果上行参考信号为SRS和DMRS，如果某个物理通道，获取到SRS，则该物理通道的信道系数即为SRS，如果某个物理通道，获取到DMRS，则该物理通道的信道系数即为DMRS，如果某个物理通道，获取到SRS和DMRS，则该物理通道的信道系数可以取二者任一。
步骤303，根据每个波束的电平，确定待分配UE在第二预设数目个正交波束组中的波束属性。
其中，波束属性用于衡量UE的特性更接近的波束，也就是表征UE在波束组上的分布特征，是方位角(Angle of Arrival，AOA)、天线相关性等的信道综合表征量。
在实施中，基站在确定每个正交波束组中的各波束的电平后，可以基于各波束的电平，确定待分配UE在每个正交波束组中的波束属性。
可选的，可以通过对比的方式，确定待分配UE的波束属性，相应的步骤303的处理可以如下：
对于每个正交波束组，如果正交波束组中存在目标波束满足预设条件，则确定待分配UE在正交波束组中的波束属性为目标波束，如果正交波束组中不存在波束满足预设条件，则确定待分配UE在正交波束组中的波束属性为联合属性。
其中，预设条件可以预设，并且存储至基站中，预设条件为目标波束的电平与正交波束 组中除目标波束之外的其它波束的电平的差值均大于预设数值，目标波束为一个或多个，预设数值可以预设，并且存储至基站中，用于衡量波束之间的相关性。
在实施中，对于任一正交波束组，基站可以比较该正交波束组中，每个波束的电平，如果该正交波束组中的目标波束的电平与该正交波束组中除目标波束之外的其它波束的电平的差值，均大于预设数值，则确定待分配UE在该正交波束组中的波束属性为目标波束。
例如，待分配UE在某个正交波束组中，电平最高的波束x(目标波束)的电平与其他波束的电平之差大于预设数值，待分配UE的波束属性为波束x，或者电平较高的多个波束x、y的电平与其他任一波束的电平的差值大于一定预设数值，则判断待分配UE的波束属性为波束x、波束y。如果该正交波束组中不存在波束满足上述预设条件，则可以确定待分配UE在该正交波束组中的波束属性为联合属性。
这样，依此类推，基于相同的方式，可以确定出待分配UE在每个正交波束组中的波束属性。
步骤304，根据待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE的波束属性，为待分配UE分配时频资源。
其中，已分配UE使用同一时频资源，且同一时频资源中的某些资源没有被占满(如同一时频资源为同一RBG，某些资源指某些RB)，且已分配的UE为一个或多个，为已分配UE指此次调度时频资源，用于基站向UE发送数据。同一时频资源指同一RBG，或同一RB，RBG中可以包括多个RB，数目可以基于业务进行配置，在本发明实施例后面描述过程中使用同一时频资源为同一RBG为例进行说明。
在实施中，基站在确定待分配UE在每个正交波束组中的波束属性后，如果当前正分配时频资源的RBG中存在没有被占满的RB，则基站可以获取RBG上的已分配UE(与待分配UE属于劈裂后的同一小区或者分别属于劈裂后的两个小区)，然后获取已分配UE在第二预设数目个波束组上每个波束组的波束属性(确定方法与前面确定待分配UE的方法相同，此处不再赘述)。然后根据待分配UE的波束属性和已分配UE的波束属性，为待分配UE分配时频资源。
另外，如果当前开始在一个新的时频资源(RB或RBG)上为待分配UE分配时频资源，由于新的时频资源上还没有为其它UE分配的时频资源，可以直接在该时频资源上为待分配UE分配时频资源。例如，如果当前开始在一个新的RBG上为待分配UE分配时频资源，由于新的RBG上还没有为其它UE分配的时频资源，可以直接在该RBG上为待分配UE分配时频资源。
可选的，还可以基于待分配UE的传输模式和波束属性，为待分配UE分配时频资源，相应的步骤304的处理可以如下
确定待分配UE的传输模式和已分配UE的传输模式；根据待分配UE的传输模式和已分配UE的传输模式、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE在第二预设数目个正交波束组中的波束属性，为待分配UE分配时频资源。
其中，基站向UE下行传输数据时，传输模式一般有多入多出MIMO传输模式、BF传输模式、发射分集等传输模式。在本发明实施例中，提到的传输模式是下行传输模式，一般是基于CRS的MIMO传输模式和BF传输模式。
在实施中，基站可以基于用于解调的参考信号来判断UE的传输模式，如果是基于CRS 进行解调，则确定UE是基于CRS的MIMO传输模式，如果是基于UE的DMRS进行解调，则确定UE是BF传输模式。基于这种原则，基站可以确定待分配UE和已分配UE的传输模式，然后根据待分配UE的传输模式和已分配UE的传输模式、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE的波束属性，为待分配UE分配时频资源。
需要说明的是，CRS是在每个下行子帧和频域的每个RB上进行传输，可以用于UE的信道估计，以及实现所有下行传输的相关解调，还可以用于UE获取信道状态信息(Channel-state Information，CSI)。DMRS是一个UE的特定参考信号，用于该UE的信道估计和相干解调，DMRS一般仅在为特定UE的PDSCH传输而分配的RB中进行传输。
可选的，可以首先确定待分配UE和已分配UE是否满足正交匹配条件，基于这个结果为待分配UE分配时频资源，相应的处理可以如下：
根据待分配UE的传输模式和已分配UE的传输模式、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE在第二预设数目个正交波束组中的波束属性，如果待分配UE和已分配UE满足正交匹配条件，则在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。
其中，正交匹配条件是指在同一RBG上下行传输数据时，相互不会干扰的两个UE所满足的条件。
在实施中，基站可以根据待分配UE的传输模式和已分配UE的传输模式、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE在第二预设数目个正交波束组中的波束属性，确定待分配UE和已分配UE是否满足正交匹配条件，如果待分配UE与已分配UE满足正交匹配条件，说明待分配UE与已分配UE中任一UE的相关性比较小，不会互相影响，可以在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。例如，如图4所示，在RBG1中，待分配UE为B小区UEo，由于UEo与UEd、UEc均满足正交匹配条件，所以UEo可以与UEd、UEc使用同一RBG1，A小区和B小区是经过劈裂后的两个小区。
另外，如果待分配UE与已分配UE不满足正交匹配条件(与已分配UE中某个UE不满足正交匹配条件)，说明待分配UE与已分配UE中该UE的相关性比较大，会互相影响，有可能会影响UE接收解调数据，所以不能在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。
另外，在待分配UE与已分配UE不满足正交匹配条件时，基站可以确定其它等待分配时频资源的UE的优先级，从中确定出优先级最高的UE，按照上述方式为UE分配时频资源，在当前RBG上的时频资源全部分配完毕后，可以在下一个RBG上，首先为待分配UE分配时频资源。
需要说明的是，上述已分配UE是多个的情况下，待分配UE和已分配UE中每个UE均满足正交匹配条件，才能确定待分配UE与已分配UE满足正交匹配条件，只要待分配UE和已分配UE中某个UE不满足正交匹配条件，则待分配UE与已分配UE不满足正交匹配条件。
可选的，在待分配UE的传输模式为基于CRS的MIMO传输模式，且在已分配UE中存在UE与待分配UE的传输模式相同时，可以按照以下方式判断是否满足正交匹配条件，相应的处理可以如下：
如果已分配UE和待分配UE中存在至少一个UE的传输模式为基于CRS的MIMO传输 模式，则获取待分配UE所属小区的物理小区标识PCI和已分配UE所属小区的PCI；根据待分配UE在第二预设数目个正交波束组中的波束属性、已分配UE在第二预设数目个正交波束组中的波束属性、待分配UE所属小区的PCI以及已分配UE所属小区的PCI，如果待分配UE和已分配UE满足正交匹配条件，则在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。
在实施中，UE在刚接入LTE网络时，基站会记录UE所属小区的物理小区标识，所以基站可以从预先记录PCI的存储位置，获取到待分配UE和已分配UE所属小区的PCI。
基站确定出待分配UE与已分配UE的传输模式后，可以判断他们中是否存在至少一个UE的传输模式为基于CRS的MIMO传输模式，如果存在，则获取待分配UE所属小区的PCI、已分配UE所属小区的PCI，然后根据获取到的PCI、以及待分配UE在第二预设数目个正交波束组中的波束属性、已分配UE在第二预设数目个正交波束组中的波束属性，来确定待分配UE与已分配UE是否满足正交匹配条件，如果满足正交匹配条件，则可以在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。
可选的，可以基于PCI，使用以下方式来判断是否满足正交匹配条件，相应的处理可以如下：
如果待分配UE的传输模式为基于CRS的MIMO传输模式，且待分配UE所属小区的PCI与已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI不相同，且待分配UE所属小区的PCI与已分配UE中传输模式为BF传输模式的UE所属小区的PCI不相同，且对于已分配UE中第一UE，在第二个预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和第一UE的波束属性均不为联合属性，且待分配UE的波束属性和第一UE的波束属性完全不相同，则待分配UE和已分配UE满足正交匹配条件，在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源，其中，第一UE为已分配UE中任一UE；
如果待分配UE的传输模式为BF传输模式，且待分配UE所属小区的PCI与已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI不相同，且对于已分配UE中第二UE，在第二个预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和第二UE的波束属性均不为联合属性，且待分配UE的波束属性和已分配UE的波束属性完全不相同，则待分配UE和已分配UE满足正交匹配条件，在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源，其中，第二UE为已分配UE中任一UE。
在实施中，如果待分配UE的传输模式为基于CRS的MIMO传输模式，则基站可以确定已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI，如果待分配UE所属小区的PCI与已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI不相同，则可以确定已分配UE中传输模式为BF传输模式的UE所属小区的PCI，如果确定待分配UE所属小区的PCI与已分配UE中传输模式为BF传输模式的UE所属小区的PCI不相同(也就是说待分配UE的传输模式为基于CRS的MIMO传输模式，已分配的UE中不存在与待分配UE所属小区的PCI相同的UE)，则可以将待分配UE的波束属性与已分配UE中任一UE(即第一UE)的波束属性进行匹配。匹配原则可以是：
对于第一UE，判断在第二预设数目个正交波束组中是否存在一个正交波束组，判断在第 二预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和已分配UE中第一UE的波束属性均不为联合属性，且他们的波束属性完全不相同，可以确定待分配UE和已分配UE中第一UE满足正交匹配条件。这样，可以确定出待分配UE与已分配UE中任一UE是否满足正交匹配条件。
如果待分配UE与已分配UE中任一UE都满足正交匹配条件，则确定待分配UE与已分配UE满足正交匹配条件。可以在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。
例如，如图5所示，在RBG2上，已分配UE有两个，UE1和UE2，待分配UE为UE3，UE1的传输模式为BF传输模式，所属小区的PCI为A，UE2的传输模式为BF传输模式，所属小区的PCI为A，UE3的传输模式为基于CRS的MIMO传输模式，所属小区的PCI为B，UE1的传输模式与UE2、UE3的传输模式均不相同，UE1和UE3所属小区的PCI不相同，UE2和UE3所属小区的小区标识也不相同。然后可以看在第二预设数目个正交波束组的第一正交波束组(第一正交波束组是第二预设数目个正交波束组中的任一波束组)中，UE1和UE3的波束属性均不是联合属性，且UE1的波束属性是波束x，UE3的波束属性是波束y，完全不相同，且UE2的波束属性为波束z，也与UE3完全不相同，可以确定UE3分别与UE1、UE2满足正交匹配条件，可以在为UE1和UE2分配的时频资源所属的RBG2中，为UE3分配时频资源。
如果待分配UE的传输模式为BF传输模式，则基站可以确定已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI，如果待分配UE所属小区的PCI与已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI不相同，则可以将待分配UE的波束属性与已分配UE中任一UE(即第二UE)的波束属性进行匹配。匹配原则可以是：
对于待分配UE与已分配UE中任一UE，判断在第二预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和已分配UE中第二UE的波束属性均不为联合属性，且他们的波束属性完全不相同，可以确定待分配UE和已分配UE中第二UE满足正交匹配条件。这样，可以确定出待分配UE与已分配UE中任一UE是否满足正交匹配条件。
如果待分配UE与已分配UE中任一UE都满足正交匹配条件，则确定待分配UE与已分配UE满足正交匹配条件。可以在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。
例如，在RBG3上，已分配UE有一个UE3，待分配UE为UE4，UE3的传输模式为基于CRS的MIMO传输模式，所属小区的PCI为A，UE4的传输模式为BF传输模式，所属小区的PCI为B，UE3和UE4所属小区的PCI不相同。然后可以看在第二预设数目个正交波束组的第一正交波束组(第一正交波束组是第二预设数目个正交波束组中的任一波束组)中，UE3和UE4的波束属性均不是联合属性，且UE3的波束属性是波束x，UE4的波束属性是波束y，完全不相同，可以确定UE4与UE3满足正交匹配条件，可以在为UE3分配的时频资源所属的RBG中，为UE4分配时频资源。
另外，如果待分配UE的传输模式为基于CRS的MIMO传输模式，已分配UE中传输模式为基于CRS的MIMO传输模式的UE中任一UE所属小区的PCI与待分配UE所属小区的PCI相同，则待分配UE和已分配UE不满足正交匹配条件，不可以在为已分配UE分配的时 频资源所属的RBG中，为待分配UE分配时频资源。
另外，如果待分配UE的传输模式为基于CRS的MIMO传输模式，已分配UE中传输模式为BF传输模式的UE中任一UE所属小区的PCI与待分配UE所属小区的PCI相同，则待分配UE和已分配UE不满足正交匹配条件。
另外，如果待分配UE的传输模式为BF传输模式，已分配UE中传输模式为基于CRS的MIMO传输模式的UE中任一UE所属小区的PCI与待分配UE所属小区的PCI相同，则待分配UE和已分配UE不满足正交匹配条件。
另外，如果待分配UE的传输模式为基于CRS的MIMO传输模式，待分配UE所属小区的PCI与已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI不相同，且待分配UE所属小区的PCI与已分配UE中传输模式为BF传输模式的UE所属小区的PCI不相同。但是在已分配UE中存在一个至少一个UE，在第二预设数目个正交波束组中不存在一个正交波束组，待分配UE的波束属性和已分配UE中该UE的波束属性不是均不为联合属性，或者均为联合属性，但是波束属性不是完全不相同，可以确定待分配UE和已分配UE中该UE不满足正交匹配条件，则待分配UE和已分配UE不满足正交匹配条件。
另外，如果待分配UE的传输模式为BF传输模式，待分配UE所属小区的PCI与已分配UE中传输模式为基于CRS的MIMO传输模式的UE所属小区的PCI不相同，且待分配UE所属小区的PCI与已分配UE中传输模式为BF传输模式的UE所属小区的PCI不相同。但是在已分配UE中存在一个至少一个UE，在第二预设数目个正交波束组中不存在一个正交波束组，待分配UE的波束属性和已分配UE中该UE的波束属性不是均不为联合属性，或者均为联合属性，但是波束属性不是完全不相同，可以确定待分配UE和已分配UE中该UE不满足正交匹配条件，则待分配UE和已分配UE不满足正交匹配条件。
可选的，在待分配UE和已分配UE不满足正交匹配条件时，基站可以确定其它等待分配时频资源的UE的优先级，从中确定出优先级最高的UE，按照上述方式为UE分配时频资源，在当前RBG上的时频资源全部分配完毕后，可以在下一个RBG上，首先为待分配UE分配时频资源。
可选的，在待分配UE和已分配UE的传输模式均为BF传输模式，可以按照以下方式判断是否满足正交匹配条件，相应的处理可以如下：
如果待分配UE和已分配UE的传输模式均为BF传输模式，且对于已分配UE中第三UE，在第二个预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和第三UE的波束属性均不为联合属性，且待分配UE的波束属性和第三UE的波束属性完全不相同，则待分配UE和已分配UE满足正交匹配条件，在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源，其中，第三UE为已分配UE中任一UE。
在实施中，基站确定出待分配UE与已分配UE的传输模式后，可以判断它们的传输模式是否相同，如果待分配UE和已分配UE的传输模式均为BF传输模式，则可以将待分配UE的波束属性与已分配UE中任一UE(即第三UE)的波束属性进行匹配。匹配原则可以是：
对于待分配UE与已分配UE中任一UE，判断在第二预设数目个正交波束组中是否存在一个正交波束组，待分配UE的波束属性和已分配UE中第三UE的波束属性均不为联合属性，且波束属性完全不相同，可以确定待分配UE和已分配UE中第三UE满足正交匹配条件。这样，可以确定出待分配UE与已分配UE中任一UE是否满足正交匹配条件。
如果待分配UE与已分配UE中任一UE都满足正交匹配条件，则确定待分配UE与已分配UE满足正交匹配条件。可以在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。
例如，已分配UE有两个UE5和UE6，待分配UE为UE7，UE5和UE6的传输模式均为BF传输模式，UE7的传输模式为BF传输模式，在第二预设数目个正交波束组中的第二正交波束组，UE5的波束属性分别为波束x，UE7的波束属性为波束p，可以确定在第二正交波束组，UE5和UE7的波束属性均不为联合属性，且他们的波束属性完全不相同，可以确定UE5与UE7满足正交匹配条件，并且在第二预设数目个正交波束组中的第三正交波束组，UE6的波束属性分别为波束z，UE7的波束属性为波束p，可以确定在第三正交波束组，UE6和UE7的波束属性均不为联合属性，且他们的波束属性完全不相同，可以确定UE6与UE7满足正交匹配条件，可以确定待分配UE和已分配UE满足正交匹配条件，可以在为UE5和UE6分配的时频资源所属的RBG中，为UE7分配时频资源。
另外，如果待分配UE和已分配UE的传输模式为BF传输模式，在已分配UE中存在一个至少一个UE，在第二预设数目个正交波束组中不存在一个正交波束组，待分配UE的波束属性和已分配UE中该UE的波束属性不是均不为联合属性，或者均为联合属性，但是波束属性不是完全不相同，可以确定待分配UE和已分配UE中该UE不满足正交匹配条件，则待分配UE和已分配UE不满足正交匹配条件。
可选的，在待分配UE和已分配UE不满足正交匹配条件时，基站可以确定其它等待分配时频资源的UE的优先级，从中确定出优先级最高的UE，按照上述方式为UE分配时频资源，在当前RBG上的时频资源全部分配完毕后，可以在下一个RBG上，首先为待分配UE分配时频资源。
在上述，为待分配UE分配时频资源后，基站可以将要传输给待分配UE的数据，映射在为待分配UE分配的时频资源上，通过该时频资源，将数据发送至待分配UE。
另外，本发明实施例中，在同一时频资源上为待分配UE分配时频资源后，还可以获取已分配UE的波束权值，并获取待分配UE的信道系数，将已分配UE的波束权值和待分配UE的信道系数组成矩阵，然后使用该矩阵，对待分配UE的信道系数和已分配UE的波束权值进行正交化处理，得到正交化的权值，基于该正交化的权值，将待分配UE的数据映射至为待分配UE分配的时频资源。
例如，已分配UE中UEa的波束权值为
Figure PCTCN2019088613-appb-000010
待分配UE信道系数为
Figure PCTCN2019088613-appb-000011
组合成矩阵为C＝[conj(W a),H b]，UEa与待分配UE信道系数正交化D＝((C H*C) -1*C H) H之后的权值为
Figure PCTCN2019088613-appb-000012
基于该权值，将待分配UE的数据映射至为待分配UE分配的时频资源。
同样，对于已分配的任一UE，在将该UE的数据映射至为该UE分配的时频资源时，也会对将该UE的信道系数和待分配UE的波束权值组成矩阵，然后使用该矩阵，对该UE的信道系数和待分配UE的波束权值进行正交化处理，得到正交化的权值，基于该正交化的权值，将该UE的数据映射至为该UE分配的时频资源。这样，由于进行了正交化处理，所以可以使待分配UE和已分配UE更准确的解调到发送给自己的数据。
本发明实施例中，可以通过UE的波束属性来配对，判断是否可以在同一时频资源中为 不同的UE分配时频资源，所以即使劈裂后的小区的UE分布不均匀，也可以灵活调度时频资源，使时频资源得到有效的利用。
本发明另一实施例，以UE向基站发送数据时，请求调度时频资源为例进行方案的说明，如图6所示，该方案的处理过程可以如下：
步骤601，在待分配UE请求调度时频资源时，获取待分配UE的上行参考信号。
其中，为待分配UE和已分配UE分配时频资源，用于传输上行数据。基站为待分配UE分配时频资源，用于待分配UE向基站传输数据。
在实施中，UE(后续可以称为是待分配UE)通过网络向外发送数据时，会请求基站为自身分配时频资源，UE会向基站发送资源调度请求，基站接收到UE发送的时频资源调度请求时，如果基站已经接收到当前周期内待分配UE发送的SRS，则可以获取当前周期内的SRS，如果基站未接收到当前周期内待分配UE发送的SRS，则可以获取上一个周期待分配UE发送的SRS。和/或基站获取UE上一次发送数据时的DMRS。
可选的，在基站同时接收到UE发送的资源调度请求时，还会先判断多个UE中优先级最高的UE，一般是基于要传输的数据类型，来判断UE的优先级，如电话语音数据的优先级最高、其次是短消息、再次之是视频数据等，将优先级最高的UE，确定为待分配UE。
步骤602，根据上行参考信号，对第一预设数目个波束组成的第二预设数目个正交波束组中每个波束进行测量，确定每个波束的电平。
其中，正交波束组是指包括的多个波束之间相互不受干扰，或者多个波束之间的干扰均小于一定阈值，不会影响数据的正常发送和接收，第一预设数目个波束可以由技术人员基于基站的天线情况配置，通过调整基站天线的加权系数和幅值等，可以将第一预设数目个波束组成第二预设数目个正交波束组，例如，一共有M个波束，每次调整基站天线的加权系数和幅值，可以将这M个波束，变成另外的M个波束，且彼此正交，通过(N-1)次调整，会得到N个正交的波束组，第二预设数目为N。电平指波束的等效功率。
在实施中，基站在获取到待分配UE的上行参考信号后，可以获取第一预设数目个波束组成的第二预设数目个正交波束组，然后分别使用该上行参考信号，对每个正交波束组中的任一波束进行测量，得到任一波束的电平。
可选的，可以先确定每个波束的等效信道响应，基于等效信道响应，确定每个波束的电平，响应的步骤602的处理可以如下：
根据上行参考信号，对第一预设数目个波束组成的第二预设数目个正交波束组中每个波束进行测量，确定每个波束的等效信道响应；根据每个波束的等效信道响应，确定每个波束的电平。
在实施中，该过程与上一个实施例中，确定波束的电平的方式相同，可以参见前面的描述，此处不再赘述。
步骤603，根据每个波束的电平，确定待分配UE在第二预设数目个正交波束组中的波束属性。
其中，波束属性用于衡量UE更接近于何种波束，后续可以基于波束属性衡量UE之间的相关性。
在实施中，基站在确定每个正交波束组中的各波束的电平后，可以基于各波束的电平， 确定待分配UE在每个正交波束组中的波束属性。
可选的，可以通过对比的方式，确定待分配UE的波束属性，相应的步骤303的处理可以如下：
对于每个正交波束组，如果正交波束组中存在目标波束满足预设条件，则确定待分配UE在正交波束组中的波束属性为目标波束，如果正交波束组中不存在波束满足预设条件，则确定待分配UE在正交波束组中的波束属性为联合属性。
其中，预设条件可以预设，并且存储至基站中，预设条件为目标波束的电平与正交波束组中除目标波束之外的其它波束的电平的差值均大于预设数值，目标波束为一个或多个，预设数值可以预设，并且存储至基站中，用于衡量波束之间的相关性。
在实施中，对于任一正交波束组，基站可以比较该正交波束组中，每个波束的电平，如果该正交波束组中的目标波束的电平与该正交波束组中除目标波束之外的其它波束的电平的差值，均大于预设数值，则确定待分配UE在该正交波束组中的波束属性为目标波束。
例如，待分配UE所在的某个正交波束组中，电平最高的波束x(目标波束)的电平与其他波束的电平之差大于预设数值，待分配UE的波束属性为波束x，或者电平较高的多个波束x、y的电平与其他任一波束的电平的差值大于一定预设数值，则判断待分配UE的波束属性为波束x、波束y。如果该正交波束组中不存在波束满足上述预设条件，则可以确定待分配UE在该正交波束组中的波束属性为联合属性。
这样，依此类推，基于相同的方式，可以确定出待分配UE在每个正交波束组中的波束属性。
步骤604，根据待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE在第二预设数目个正交波束组中的波束属性，如果待分配UE和已分配UE满足正交匹配条件，则在为已分配UE分配的时频资源所属的同一时频资源中，为待分配UE分配时频资源。
其中，已分配UE使用同一时频资源，且同一时频资源中的某些资源没有被占满(如同一时频资源为同一RBG，某些资源指某些RB)，且已分配的UE为一个或多个，为已分配UE指此次调度时频资源，用于UE向基站发送数据。同一时频资源指同一资源块组，或同一时频资源块RB，RBG中可以包括多个RB，数目可以基于业务进行配置，在本发明实施例后面描述过程中使用同一时频资源为同一RBG为例进行说明。
在实施中，基站在确定待分配UE在每个正交波束组中的波束属性后，如果当前正分配时频资源的RBG中存在没有被占满的RB，则基站可以确定RBG上，已分配UE(与待分配UE属于劈裂后的同一小区或者分别属于劈裂后的两个小区)，然后获取已分配UE在第二数目个正交波束组中每个波束组的波束属性，根据待分配UE的波束属性和已分配UE的波束属性，确定待分配UE与已分配UE是否满足正交匹配条件，如果满足正交匹配条件，可以在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。
另外，如果当前开始在一个新的RBG上为UE分配时频资源，则直接在该RBG上为待分配UE分配时频资源。
另外，如果待分配UE与已分配UE不满足正交匹配条件(与已分配UE中任一UE不满足正交匹配条件)，说明待分配UE与已分配UE的相关性比较大，会互相影响，有可能会影响UE接收解调数据，所以不能在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。
另外，在待分配UE与已分配UE不满足正交匹配条件时，基站可以确定其它等待分配时频资源的UE的优先级，从中确定出优先级最高的UE，按照上述方式为UE分配时频资源，在当前RBG上的时频资源全部分配完毕后，可以在下一个RBG上，首先为待分配UE分配时频资源。
可选的，可以基于待分配UE与已分配UE所属小区的小区标识，确定待分配UE与已分配UE是否满足正交匹配条件，相应的处理可以如下：
获取待分配UE所属小区的PCI和已分配UE所属小区的PCI；根据待分配UE所属小区的PCI和已分配UE所属小区的PCI、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE在第二预设数目个正交波束组中的波束属性，如果待分配UE和已分配UE满足正交匹配条件，则在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。
在实施中，UE在刚接入LTE网络时，基站会记录UE所属小区的PCI，所以基站可以从预先记录PCI的存储位置，获取到待分配UE和已分配UE所属小区的PCI。
基站在确定待分配UE在每个正交波束组中的波束属性后，如果当前正分配时频资源的RBG中存在没有被占满的RB，则基站可以确定RBG上，已分配UE(与待分配UE属于劈裂后的同一小区或者分别属于劈裂后的两个小区)，然后获取已分配UE在第二数目个正交波束组中每个波束组的波束属性。然后基站可以根据待分配UE所属小区的PCI和已分配UE所属小区的PCI、待分配UE在第二预设数目个正交波束组中的波束属性和已分配UE在第二预设数目个正交波束组中的波束属性，确定待分配UE和已分配UE是否满足正交匹配条件，如果满足正交匹配条件，可以在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。
可选的，可以基于待分配UE与已分配UE所属小区的小区标识，确定待分配UE与已分配UE是否满足正交匹配条件，相应的处理可以如下：
如果待分配UE所属小区的PCI和已分配UE中任一UE所属小区的PCI不相同，且对于已分配UE中第四UE，在第二个预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和第四UE的波束属性均不为联合属性，且待分配UE的波束属性和第四UE的波束属性完全不相同，则待分配UE和已分配UE满足正交匹配条件，在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源，其中，第四UE为已分配UE中任一UE。
在实施中，基站可以确定待分配UE和已分配UE所属小区的PCI是否相同，如果不相同，可以将待分配UE的波束属性与已分配UE中任一UE(即第四UE)的波束属性进行匹配。
匹配原则可以是：对于第四UE，判断在第二预设数目个正交波束组中是否存在一个正交波束组，判断在第二预设数目个正交波束组中存在至少一个正交波束组，待分配UE的波束属性和已分配UE中第四UE的波束属性均不为联合属性，且他们的波束属性完全不相同，可以确定待分配UE和已分配UE中第四UE满足正交匹配条件。这样，可以确定出待分配UE与已分配UE中任一UE是否满足正交匹配条件。
如果待分配UE与已分配UE中任一UE都满足正交匹配条件，则确定待分配UE与已分配UE满足正交匹配条件。可以在为已分配UE分配的时频资源所属的RBG中，为待分配 UE分配时频资源。
另外，如果待分配UE所属小区的PCI和已分配UE中任一UE所属小区的PCI相同，则待分配UE和已分配UE不满足正交匹配条件，不可以在为已分配UE分配的时频资源所属的RBG中，为待分配UE分配时频资源。可选的，基站可以确定其它等待分配时频资源的UE的优先级，从中确定出优先级最高的UE，按照上述方式为UE分配时频资源，在当前RBG上的时频资源全部分配完毕后，可以在下一个RBG上，首先为待分配UE分配时频资源。
在上述，为待分配UE分配时频资源后，基站可以将为待分配UE分配的时频资源通知给UE，UE可以在该时频资源上，向基站发送数据。
需要说明的是，在上行调度时频资源时，由于同频劈裂成两个小区，由于有待分配UE所属小区的PCI与已分配UE所属小区PCI不相同的限制，在一个RBG中，仅能为两个UE调度时频资源，且两个UE属于不相同的小区。例如，如图7所示，在RGB0中，只有A小区的UEa和B小区的UEb。
需要说明的是，现有技术中，要在同一RBG上传输多个UE的上行数据，多个UE所占用的RE的数目必须完全相同，而本发明实施例中，只要满足正交匹配条件，说明UE的相关性比较小，相互影响就比较少，无关占用的资源单元(Resource Element，RE)的数目，所以占用的RE的数目不必完全相同。
需要说明的是，在本申请的上述两个实施例中，是将一个小区软劈裂成两个小区为例进行说明，在后续使用过程中，软劈裂成其他数目的小区，均可以应用本申请的上述两个实施例。
本发明实施例中，可以通过UE的波束属性来配对，判断是否可以在同一时频资源中为不同的UE分配时频资源，所以即使劈裂后的小区的UE分布不均匀，也可以灵活调度时频资源，使时频资源得到有效的利用。
