Description

一种新无线网络抗干扰方法 技术领域
本申请实施例涉及通信领域，尤其涉及一种新无线网络抗干扰方法、新无线基站以及用户设备。
背景技术
由于新无线(new radio，NR)通信系统基于全波束空口设计，而且没有小区级持续发送的参考信号，因此长期演进(long term evolution，LTE)小区会对相邻的NR小区造成较大的同频干扰影响。尤其是在NR网络部署初期，由于NR网络的用户相对于LTE网络的用户较少，LTE网络处于相对重载状态，此时处于相对重载状态的LTE小区对处于相对轻载状态下的NR小区的同频干扰影响会进一步扩大。
相关技术中，为了降低LTE小区对相邻的NR小区造成的同频干扰，运营商只能通过部署缓冲区的方式将LTE小区对相邻的NR小区造成的同频干扰降低到最小，具体部署缓冲区的方法是在NR小区与LTE小区之间规划足够的地理间隔，将LTE小区对相邻的NR小区造成的同频干扰降低到可以接受的程度。
虽然部署缓冲区可以降低LTE小区对相邻的NR小区造成的同频干扰，但是也会造成LTE网络和NR网络的覆盖空洞，影响LTE网络和NR网络的连续性。

具体实施方式
本申请实施例提供了一种新无线网络抗干扰方法，用于降低LTE小区对相邻的NR小区造成的同频干扰。
由于新无线(new radio，NR)通信系统基于全波束空口设计，而且没有小区级持续发送的参考信号，因此长期演进(long term evolution，LTE)小区会对相邻的NR小区造成较大的同频干扰影响。尤其是在NR网络部署初期，由于NR网络的用户相对于LTE网络的用户较少，LTE网络处于相对重载状态，此时处于相对重载状态的LTE小区对处于相对轻载状态下的NR小区的LTE小区参考信号(cell reference signal，CRS)干扰影响会进一步扩大。而在NR网络的部署初期，LTE网络的用户和NR网络的用户在一段时间需要保持共存，所以LTE小区对相邻的NR小区造成的同频干扰会对NR网络的用户的使用体验造成很大的影响。
请参阅图1，在相关技术中，由于现有技术中并未制定相关的通用抗干扰算法来降低LTE小区对相邻的NR小区所造成的同频干扰，因此为了降低LTE小区对相邻的NR小区造 成的同频干扰，运营商只能通过部署地理隔离缓冲区的方式将LTE小区对相邻的NR小区造成的同频干扰降低到最小，具体部署缓冲区的方法是在NR小区与LTE小区之间规划足够的地理间隔，将LTE小区对相邻的NR小区造成的同频干扰降低到可以接受的程度。缓冲区的规划需要根据LTE和NR小区的天线挂高、方位角、下倾角等工程参数，根据不同的传播环境、不同地理区域以及所使用的频段通过规划工具来进行设计规划，最终得到满足要求的缓冲区域地理面积尺寸。
请参阅图2A、图2B和图2C，虽然部署地理隔离缓冲区可以降低相邻的LTE小区对NR小区造成的同频干扰，但是也会造成LTE网络和NR网络的覆盖空洞，对于LTE网络和NR网络的连续性覆盖的影响非常大。而且很明显，部署地理隔离缓冲区的方法不支持LTE网络和NR网络共同覆盖同一区域的方案。具体地，一方面，在NR小区覆盖范围内的LTE网络的用户将无法正常使用LTE网络，同时在LTE小区覆盖范围内的NR网络的用户也将无法正常使用NR网络，在NR网络部署的初期，NR网络的用户较少，LTE网络的用户依然在增长中，因此需要如图2A所示的LTE和NR(LTE and NR，LNR)网络插花组网，而部署地理隔离缓冲区的方案并不支持LNR插花组网；另一方面，对于NR小区与LTE小区动态频谱共享(dynamic spectrum sharing，DSS)的场景，无论是如图2B所示的NR小区与LTE小区具有不同的带宽频谱场景，还是如图2C所示的NR小区与LTE小区具有相同的带宽频谱场景，LTE网络和NR网络必然存在共同覆盖区域，因此部署缓冲区也不支持该场景。
请参阅图3，本申请实施例中，NR小区内的用户设备会受到来自相邻的LTE小区1和LTE小区2的同频信号干扰，邻区LTE小区可以是2 CRS port的LTE小区，也可以是4 CRS port的LTE小区，NR小区内覆盖范围内的用户设备都配置有梳状抗干扰信息，梳状抗干扰信息包括梳状抗干扰图样，NR小区内受到邻区LTE小区的信号干扰比较强的用户设备1会使抗干扰图样生效来降低邻区LTE小区的信号干扰。
具体地，请参阅图4，首先，NR小区对应的基站会获取相邻的至少一个LTE小区的CRS网络配置信息，NR小区对应的基站根据该CRS网络配置信息为NR小区内的目标用户设备配置梳状抗干扰配置信息，并将该梳状抗干扰配置信息发送给NR小区内的目标用户设备，梳状抗干扰配置信息包括梳状抗干扰图样，然后受到相邻的至少一个LTE小区的干扰信号强的目标用户设备会使抗干扰图样生效来降低邻区LTE小区的信号干扰。
本申请实施例中，NR小区向目标用户设备发送的梳状抗干扰配置信息中的梳状抗干扰图样可能是周期性梳状抗干扰图样，也可能是动态梳状抗干扰图样，下面分别进行说明：
一、NR小区向目标用户设备发送的梳状抗干扰配置信息中的梳状抗干扰图样是周期性梳状抗干扰图样。
请参阅图5，本申请实施例中NR网络抗干扰方法的一个流程包括：
501、NR小区对应的基站获取相邻的LTE小区的网络配置信息。
NR小区对应的基站获取相邻的至少一个LTE小区的CRS网络配置信息，该网络配置信息包括该至少一个LTE小区的网络端口数。具体地，NR小区对应的基站与至少一个LTE小区对应的基站并不是同一个基站，该至少一个LTE小区的CRS网络配置信息存储在该至少一个LTE小区对应的基站，NR小区对应的基站通过与该至少一个LTE小区对应的基站之间 的信令交互获取该至少一个LTE小区的CRS网络配置信息，NR小区对应的基站与至少一个LTE小区对应的基站之间可以通过查询异系统邻区的配置的方式来获取该至少一个LTE小区的CRS网络配置信息。
一种可能的实现方式中，NR小区对应的基站与至少一个LTE小区对应的基站是同一个基站，例如在NR小区与LTE小区频谱共享的场景下，NR小区与LTE小区对应的基站可以是同一个基站，该至少一个LTE小区的网络配置信息存储在该至少一个LTE小区对应的基站，则该NR小区对应的基站提取自身存储的该至少一个LTE小区的网络配置信息。
本申请实施例中，NR小区对应的基站与至少一个LTE小区对应的基站可以是同一个基站，也可以是不同的基站，具体此处不做限定。
502、NR小区对应的基站根据网络配置信息确定梳状抗干扰配置信息。
NR小区根据相邻的至少一个LTE小区的CRS网络配置信息确定梳状抗干扰配置信息，该梳状抗干扰配置信息包括梳状抗干扰图样。
具体地，NR小区对应的基站可以根据相邻的至少一个LTE小区的CRS网络配置信息的网络端口数确定该至少一个LTE小区的CRS干扰信号对应的至少一个时域频率图，该至少一个时域频率图指示该相邻的至少一个LTE小区的CRS干扰信号的时域位置和频率的分布；并根据该至少一个时域频率图确定该至少一个LTE小区的所有的CRS干扰信号对应的一个目标时域频率图，该目标时域频率图指示该至少一个LTE小区的所有的CRS干扰信号的时域位置和频率的分布。
具体地，请参阅图6A、图6B和图6C，图6A指示的是第一LTE小区的CRS干扰信号的时域位置和频率的分布，该第一LTE小区的CRS干扰信号的时域位置所在的时域位置为0、4、7和11，其他时域位置并不存在CRS干扰信号；图6B指示的是该第二LTE小区的时域频率图描述的是LTE邻区二的CRS干扰信号的时域位置和频率的分布，该LTE邻区二的CRS干扰信号的时域位置是0、1、4、7、8和11，其他时域位置并不存在CRS干扰信号；图6C指示的是该第一LTE小区和该第二LTE小区的所有CRS干扰信号的时域位置和频率的分布。
请参阅图6D，NR小区对应的基站根据该目标时域频率图确定梳状抗干扰图样，该梳状抗干扰图样包括多个条状区域，每个条状区域指示一个指定时域位置的所有频率区域，该多个条状区域中包括间隔分布的第一区域和第二区域，该第一区域用于承载该NR小区的业务信号，该第二区域用于承载该至少一个LTE小区的CRS干扰信号。具体如图6D中的第一梳状抗干扰图样，时域位置为0、1、4、7、8和11的多个条状区域为多个第二区域，时域位置为2、3、5、6、9、10、12和13的多个条状区域为多个第一区域；该基站根据目标用户设备的能力确定该梳状抗干扰图样为周期性生效的梳状抗干扰图样。
具体地，NR小区对应的基站若确定一个指定的时域位置为该至少一个LTE小区的CRS干扰信号所对应的时域位置，则该基站确定该时域位置的所有频率区域为用于承载该至少一个LTE小区的CRS干扰信号的第二区域，即速率匹配区域；若该基站确定一个指定的时域位置与至少一个LTE小区的CRS干扰信号所对应的时域位置中的任何一个都不相同，则该基站确定该时域位置的所有频率区域为用于承载NR小区的业务信号的第一区域；该基站根据所有的第一区域和第二区域确定梳状抗干扰图样。
请参阅图6E和图6F，一种可能的实现方式中，由于该至少一个LTE小区的CRS干扰信号占用的时域符号位置比较固定，常为0、4、7和11和0、1、4、7、8和11这两种，因此在只考虑一个相邻的LTE小区的信号干扰或者该至少一个LTE小区的CRS干扰信号占用的时域符号位置只有一种类型的情况下，NR小区对应的基站可以根据该至少一个LTE小区的CRS网络配置信息中快速确定梳状抗干扰图样。如图6E所示，当该至少一个LTE小区的CRS干扰信号占用的时域符号位置为0、4、7和11时，即该至少一个LTE小区的CRS干扰信号为2PORT CRS干扰信号，则该NR小区对应的基站确定LTE-CRS 2PORT梳状抗干扰图样为第二梳状抗干扰图样；如图6F所示，当该至少一个LTE小区的CRS干扰信号占用的时域符号位置为0、1、4、7、8和11时，即该至少一个LTE小区的CRS干扰信号为4PORT CRS干扰信号，NR小区对应的基站确定LTE-CRS 4PORT梳状抗干扰图样为第三梳状抗干扰图样。
NR小区根据梳状抗干扰图样为目标用户设备确定梳状抗干扰配置信息，梳状抗干扰配置信息包括梳状抗干扰图样，该梳状抗干扰图样可以是具体地一幅图像，也可以是其他格式的可以指示该梳状抗干扰图样的对应的内容的信息。具体地，该梳状抗干扰配置信息中可以包括RRC信令的信元RateMatchPattern，当配置LTE-CRS 2PORT抗干扰图样时，RateMatchPattern所对应的ONE SLOT BIT STRING配置为10001001000100，或者所对应的TWO SLOT BIT STRING配置为1000100100010010001001000100。当配置LTE-CRS 4PORT抗干扰图样时，RateMatchPattern所对应ONE SLOT BIT STRING配置为STRING:11001001100100，或者所对应的TWO SLOT BIT STRING配置为1100100110010011001001100100。该RRC标准信令包括RRCReconfiguration信令或RRCSetup信令，除此之外，该RRC标准信令还可以是其他信令，具体此处不做限定。
具体地，该梳状抗干扰配置信息可以包括梳状抗干扰图样和其他抗干扰信息，该其他抗干扰信息指示该梳状抗干扰图样的作用、指示的信息以及如何使该梳状抗干扰图样生效的等相关的其他抗干扰信息；该梳状抗干扰配置信息也可以只包括梳状抗干扰图样，在基站和目标用户设备在发送该梳状抗干扰配置信息之前就成功配置了该梳状抗干扰图样的作用、指示的信息以及如何使该梳状抗干扰图样生效的等相关的其他抗干扰信息，具体此处不做限定。
请参阅图7A和图7B，一种可能的实现方式中，当NR小区对应的基站在梳状抗干扰配置信息中需要为用户设备配置提高用户设备的解调能力的附加导频信息时，若NR小区确定该附加导频所对应的时域位置在梳状抗干扰图样中属于用于承载干扰信号的时域位置，即属于第二区域，如图7A所示；则该基站用承载业务信号的第一区域承载该附加导频信息，如图7B所示。
具体地，当NR小区对应的基站需要为用户设备配置附加导频时，通过RRC标准信令在梳状抗干扰配置信息中配置LTE CRS RateMatch指示，通过该指示可以将附加导频信息配置到梳状抗干扰配置信息中，该RRC标准信令中包含Lte-CRS-ToMatchAround标准信元。NR小区对应的基站确定附加导频在梳状抗干扰图样中对应的时域位置为11，而时域位置11是用于承载干扰信号的时域位置，此时附加导频与梳状抗干扰配置信息产生了冲突。因此NR小区对应的基站确定满足第一预设条件时，则该基站用承载业务信号的第一区域承载 该附加导频信息，即用时域位置12承载该附加导频信息，而时域位置12是用于承载业务信号的第一区域，这样就解决了附加导频与梳状抗干扰配置信息的冲突，目标用户设备可以同时应用这两种配置。
具体地，NR小区对应的基站的第一预设条件包括：(1)NR小区对应的基站向目标用户设备配置了Lte-CRS-ToMatchAround信元；(2)该目标用户设备前置导频配置为POS3且该附加导频配置为POS1；(3)该目标用户设备支持additionalDMRS-DL-Alt附加导频移位能力。除此之外，该第一预设条件还可以是其他条件，具体此处不做限定。
503、NR小区对应的基站向目标用户设备发送梳状抗干扰配置信息。
NR小区向目标用户设备发送梳状抗干扰配置信息，相应地，目标用户设备接收NR小区发送的梳状抗干扰配置信息。
504、目标用户设备根据梳状抗干扰配置信息使梳状抗干扰图样生效。
由于NR小区对应的基站向目标用户设备发送的梳状抗干扰图样是周期性梳状抗干扰图样，所以目标用户设备在这个周期内会根据梳状抗干扰配置信息中的周期性梳状抗干扰图样使该梳状抗干扰图样生效，即使用该梳状抗干扰图样中的第一区域承载NR小区对应的基站与目标用户设备之间的业务信号。
本申请实施例中，NR小区向目标用户设备发送的梳状抗干扰配置信息中的梳状抗干扰图样是周期性梳状抗干扰图样，该梳状抗干扰图样也可以是动态梳状抗干扰图样，下面具体进行说明：

805、基站接收目标用户设备发送的信号质量信息。
目标用户设备向NR小区对应的基站发送信号质量信息，相应地，NR小区对应的基站接收目标用户设备发送的信号质量信息。
806、基站确定信号质量信息满足第二预设条件，则基站向目标用户设备发送梳状抗干扰开启指令。
NR小区对应的基站确定目标用户设备发送的信号质量信息满足第二预设条件，NR小区对应的基站向目标用户设备发送梳状抗干扰开启指令，该指令指示目标用户设备使抗干扰图样生效，相应地，目标用户设备接收NR小区发送的梳状抗干扰开启指令。
该第二预设条件包括：(1)信号质量信息中的SSB RSRP测量值、SSB RSRQ测量值和SSB SINR测量值中的一个或多个低于第一预设指标；(2)信号质量信息中的CSI-RS RSRP测量值、CSI-RS RSRQ测量值和CSI-RS SINR测量值中的一个或多个低于第二预设指标；(3)信号质量信息中的CSI-RS CQI测量值、CSI-RS PMI测量值、CSI-RS RI测量值中的一个或多个低于第三预设指标；(4)梳状抗干扰图样生效后目标用户设备与NR小区对应的基站之间的业务信号的频谱效率高于第四预设指标；该第二预设条件还可以是上述四个条件中的至少两个的组合。除此之外，本申请实施例中的第二预设条件还可以是或者其他预设条件，具体此处不做限定。
807、目标用户设备根据梳状抗干扰开启指令使动态梳状抗干扰图样生效。
