Description

接入点干扰协调方法及基站、用户设备、可读存储介质
本申请要求于2020年11月27日提交中国专利局、申请号为202011360189.7、发明名称为“接入点干扰协调方法及基站、用户设备、可读存储介质”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
本发明涉及无线通信技术领域，尤其涉及一种接入点干扰协调方法及基站、用户设备、可读存储介质。
背景技术
在现有的一种网络系统中，一个用户设备(User Equipment，UE)可以通过一个接入点(Access Point，AP)接入互联网。用户设备与接入点之间采用LTE或者新空口(New Radio，NR)的无线通信技术。AP可以继承部分核心网的功能，部署在授权频谱或者非授权频谱。
接入点AP可以灵活地布置在家庭、企业等场所，为小部分用户提供服务。能够接入AP的用户设备可以简称为签约用户。AP与宏网构成异构网络，其发射功率较小，覆盖范围有限，可以与宏网同频或异频部署。若AP与宏网异频部署，则可能会产生干扰。
当没有权限的接入AP的宏网用户设备靠近AP后，AP会对该用户设备造成下行链路干扰。现有的方案中，可以通过基站间干扰协调调整AP的发射功率，或者对该用户设备进行异频切换或者重定向以使其避免同频干扰。
但是，由于AP小区覆盖较小，在一个宏小区中可能存在较多的 AP，或者AP小区的配置不受某一运营商控制，导致宏小区可能不会配置相关AP邻区信息。因此，何时触发用户设备进行AP发现，以及如何判断用户设备是否为签约用户，现有技术中均未涉及，进而导致没有权限接入AP的用户设备受到干扰导致掉话的情况出现。
发明内容
本发明实施例解决的是如何降低AP对没有权限接入AP的用户设备的干扰。

具体实施方式
如上所述，由于AP小区覆盖较小，在一个宏小区中可能存在较多的AP，或者AP小区的配置不受某一运营商控制，导致宏小区可能不会配置相关AP邻区信息。因此，何时触发用户设备进行AP发现，以及如何判断用户设备是否为签约用户，现有技术中均未涉及，进而导致没有权限接入AP的用户设备受到干扰导致掉话的情况出现。
在本发明实施例中，为用户设备配置并下发进行接入点小区测量的触发条件，用户设备在接收到触发条件后执行相应的接入点小区测量，进行接入点发现。在查找到目标接入点之后，用户设备将目标接入点的标识信息以及自身的标识信息上报，使得基站能够获知目标接入点的标识信息、所述用户设备的标识信息。基站将用户设备的标识信息发送至目标接入点，使得目标接入点获知用户设备的标识信息，进而能够判断用户设备是否为签约用户。在确定用户为非签约用户时，对用户设备进行干扰协调，从而降低目标接入点对非签约用户的干扰。
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下 面结合附图对本发明的具体实施例做详细的说明。
本发明实施例提供了一种接入点干扰协调方法，参照图1，以下通过具体步骤进行详细说明。
在具体实施中，下述步骤S101～步骤S105所提供的接入点干扰协调方法可以由基站中具有数据处理功能的芯片执行，或者由基站中包含有数据处理功能的芯片的芯片模组执行。
步骤S101，为用户设备配置并向所述用户设备下发进行接入点小区测量的触发条件。
在具体实施中，基站可以为用户设备配置进行接入点小区测量的触发条件，并将配置的触发条件下发至用户设备。用户设备在接收到触发条件后，可以自行触发接入点小区测量，也可以在接收到基站下发的指示信息后再触发接入点小区测量。
在本发明实施例中，接入点小区也可以称为小小区(small cell)，或者非公共网络小区(Non-public network cell，NPN cell)。本发明实施例中所述的基站可以是宏小区基站gNB，也可以是接入点小区基站。
在具体实施中，基站配置的触发条件可以包括干扰测量门限。
在本发明一实施例中，用户设备在接收到触发条件之后，检测当前服务小区的信号质量。若检测到当前服务小区的信号质量低于预设的干扰测量门限，则用户设备自行触发接入点小区测量。
在本发明另一实施例中，用户设备在接收到触发条件之后，检测当前服务小区的信号质量。若检测到当前服务小区的信号质量低于预设的干扰测量门限，则用户设备向基站上报测量结果或上报满足接入点小区测量条件的指示。基站在接收到测量结果或指示之后，获知用户设备当前服务小区的信号质量较差，则向用户设备发送触发指示。用户设备在接收到触发指示后，进行接入点小区发现或测量。
在具体实施中，干扰测量门限可以为信干噪比(SINR)门限，也可以为参考信号接收质量(RSRQ)门限，还可以为其他能够表征当前服务小区由于受到邻近接入点小区干扰的信号质量的门限。
在具体实施中，基站配置的触发条件可以包括波束标识信息。
在本发明实施例中，用户设备在接收到触发条件之后，检测当前服务小区波束的标识信息。若当前服务小区波束的标识信息与触发条件所包含的波束标识信息相同，则触发接入点小区测量。其中，波束标识信息可以是用户正在接收数据的beam index，或者SSB index，或者CSI-RS index。
例如，触发条件中指示波束的标识信息为2，也即波束2(beam 2)。用户设备在接收到触发条件之后，检测到当前服务小区的波束为beam 2，则触发接入点小区测量。
在具体实施中，基站配置的触发条件也可以同时包括干扰测量门限以及波束标识信息。
在本发明实施例中，用户设备在接收到触发条件之后，检测当前服务小区波束的标识信息。若当前服务小区波束的标识信息与触发条件所包含的波束标识信息相同，测量当前服务小区的信号质量。若检测到当前服务小区的信号质量低于预设的干扰测量门限，则触发接入点小区测量，或将测量结果或指示上报至基站。
例如，用户设备当前服务小区存在4个beam。基站配置的触发条件包括：beam 2，干扰测量门限1；beam 3，干扰测量门限2。干扰测量门限1与干扰测量门限2可以相等，也可以不等。用户设备在接收到触发条件之后，若当前正在使用的波束为beam 2，则用户设备测量当前服务小区的SINR，若SINR小于预设的干扰测量门限，则触发接入点小区测量。
步骤S102，接收所述用户设备的上报信息。
在具体实施中，用户设备在触发进行接入点小区测量后，可以搜 索接入点信号，获取目标接入点的标识信息，并将目标接入点的标识信息作为上报信息，发送至基站。
在本发明实施例中，用户设备的上报信息中，还可以携带有用户设备的标识信息。基站在接收到用户设备的上报信息后，即可获知目标接入点的标识信息以及用户设备的标识信息。
在本发明实施例中，基站也可以预先存储有用户设备的标识信息。如果用户设备没有上报其标识信息，基站可以使用已存储的所述用户设备的标识信息。
在本发明实施例中，目标接入点的标识信息可以为目标接入点对应小区的全球小区识别码(Cell Global Identifier，CGI)，也可以为接入点基站标识，目标接入点的标识信息还可以包括目标接入点的可寻址地址、IP地址等其他能够标识目标接入点的信息。其中，所述接入点标识信息可以通过用户设备读取接入点基站广播获得。
上报信息还可以包括目标接入点的波束信息，目标接入点的波束信息可以为干扰用户设备的波束的标识或者用户设备收到接入点基站发送的SSB标识信息。上报信息还可以包括目标接入点小区对应的测量结果。
在本发明实施例中，用户设备的标识信息可以为用户设备的国际移动用户识别码(International Mobile Subscriber Identity，IMSI)，也可以为用户设备在签约时预留的签约信息，也可以为手机号码等其他能够标识用户设备的信息。
步骤S103，根据所述目标接入点的标识信息确定目标接入点，并将用户设备的标识信息发送至所述目标接入点。
在具体实施中，基站可以根据接收到的上报信息，确定用户设备搜索到的目标接入点。基站可以根据目标接入点的标识信息，寻址到目标接入点。基站可以将用户设备的标识信息发送至目标接入点。目标接入点在接收到用户设备的标识信息后，可以判断该用户设备是否 为签约用户，得到鉴权结果。基站可以通过核心网寻址到目标接入点基站，或者直接通过接入点标识寻址到目标接入点基站。
在本发明实施例中，非签约用户与签约用户为相对概念。在本发明实施例中，对应于目标AP而言，能够接入目标AP的用户设备可以简称为签约用户，也即签约用户具有接入目标AP的权限。相应地，不具有接入目标AP权限的宏网用户设备称之为非签约用户。
在实际应用中，目标接入点中可以预先存储有签约用户对应的标识信息。目标接入点在接收到用户设备的标识信息之后，可以判断该用户设备的标识信息是否已经被存储。若该用户设备的标识信息未被预先存储，则目标接入点判定该用户设备为非签约用户；反之，若该用户设备的标识信息已被预先存储，则目标接入点判定该用户设备为签约用户。
步骤S104，接收所述目标接入点反馈的鉴权结果。
在具体实施中，目标接入点在得到鉴权结果之后，可以将鉴权结果上报至基站。基站根据接收到鉴权结果，可以获知用户设备为签约用户还是非签约用户。
步骤S105，在确定所述用户设备为非签约用户时，对所述用户设备进行干扰协调。
在具体实施中，基站若确定用户设备为非签约用户，则可以对用户设备进行干扰协调。对用户设备进行干扰协调，其目的是降低目标接入点对用户设备(非授权用户)的干扰。
在本发明实施例中，基站对用户设备进行干扰协调，可以为配置用户设备进行异频切换，也即将用户设备当前驻留的频率切换至其他频率，从而有效避免目标接入点对用户设备的同频干扰。
在本发明实施例中，若用户设备发送的上报信息还包括目标接入点的波束信息，则在对用户设备进行干扰协调时，基站还可以协调目标接入点降低波束信息对应波束的功率，也即降低目标接入点所使用 的波束的功率，以降低对用户设备的干扰。
在具体实施中，若用户设备为签约用户，则基站可以为用户设备后续可能的切换做准备。
在本发明实施例中，目标接入点可以将其对应的小区测量配置信息发送至基站。基站可以将接收到的小区测量配置信息下发至用户设备。用户设备可以根据接收到的小区测量配置信息，进行目标接入点对应的小区测量。
在本发明实施例中，测量配置信息可以包括参考信号配置信息、测量周期和长度等信息(SMTC)，参考配置信息可以包括同步信号块、CSI-RS等信息。测量配置信息所包含的内容可以参照现有技术，本发明实施例不做赘述。
在具体实施中，测量配置信息可以与鉴权结果配置在同一个消息中。用户设备在接收到该消息时，即可获知其为签约用户，以及对应的进行小区测量的测量配置信息。
可见，在本发明实施例中，为用户设备配置并下发进行接入点小区测量的触发条件，用户设备在接收到触发条件后执行相应的接入点小区测量，进行接入点发现。在查找到目标接入点之后，用户设备将目标接入点的标识信息以及自身的标识信息上报，使得基站能够获知目标接入点的标识信息、所述用户设备的标识信息。基站将用户设备的标识信息发送至目标接入点，使得目标接入点获知用户设备的标识信息，进而能够判断用户设备是否为签约用户。在确定用户为非签约用户时，对用户设备进行干扰协调，从而降低目标接入点对非签约用户的干扰。
参照图2，给出了本发明实施例中的另一种接入点干扰协调方法，以下通过具体步骤进行详细说明。
在具体实施中，下述步骤S201～步骤S203所提供的接入点干扰协调方法可以由用户设备中具有数据处理功能的芯片(如基带芯片) 执行，或者由用户设备中包含有数据处理功能的芯片(如基带芯片)的芯片模组执行。
步骤S201，接收基站下发的接入点小区测量的触发条件。

在本发明实施例中，接入点小区也可以称为小小区(small cell)，或者非公共网络小区(Non-public network cell，NPN cell)。本发明实施例中所述的基站可以是宏小区基站gNB，也可以是接入点小区基站。
在具体实施中，基站配置的触发条件可以包括干扰测量门限。

在具体实施中，干扰测量门限可以为信干噪比(SINR)门限，也可以为参考信号接收质量(RSRQ)门限，还可以为其他能够表征当前服务小区由于受到邻近接入点小区干扰的信号质量的门限。
在具体实施中，基站配置的触发条件可以包括波束标识信息。
在本发明实施例中，用户设备在接收到触发条件之后，检测当前 服务小区波束的标识信息。若当前服务小区波束的标识信息与触发条件所包含的波束标识信息相同，则触发接入点小区测量。其中，波束标识信息可以是用户正在接收数据的beam index，或者SSB index，或者CSI-RS index。
例如，触发条件中指示波束的标识信息为2，也即波束2(beam 2)。用户设备在接收到触发条件之后，检测到当前服务小区的波束为beam 2，则触发接入点小区测量。
在具体实施中，基站配置的触发条件也可以同时包括干扰测量门限以及波束标识信息。
在本发明实施例中，用户设备在接收到触发条件之后，检测当前服务小区波束的标识信息。若当前服务小区波束的标识信息与触发条件所包含的波束标识信息相同，测量当前服务小区的信号质量。若检测到当前服务小区的信号质量低于预设的干扰测量门限，则触发接入点小区测量，或将测量结果或指示上报至基站。
例如，用户设备当前服务小区存在4个beam。基站配置的触发条件包括：beam 2，干扰测量门限1；beam 3，干扰测量门限2。干扰测量门限1与干扰测量门限2可以相等，也可以不等。用户设备在接收到触发条件之后，若当前正在使用的波束为beam 2，则用户设备测量当前服务小区的SINR，若SINR小于预设的干扰测量门限，则触发接入点小区测量。
步骤S202，向所述基站发送上报信息，所述上报信息包括目标接入点的标识信息。
在具体实施中，用户设备在触发进行接入点小区测量后，可以搜索接入点信号，获取目标接入点的标识信息，并将目标接入点的标识信息作为上报信息，发送至基站。
在本发明实施例中，用户设备的上报信息中，还可以携带有用户设备的标识信息。基站在接收到用户设备的上报信息后，即可获知目 标接入点的标识信息以及用户设备的标识信息。
在本发明实施例中，基站也可以预先存储有用户设备的标识信息。如果用户设备没有上报其标识信息，基站可以使用已存储的所述用户设备的标识信息。
在本发明实施例中，目标接入点的标识信息可以为目标接入点对应小区的全球小区识别码(Cell Global Identifier，CGI)，也可以为接入点基站标识，目标接入点的标识信息还可以包括目标接入点的可寻址地址、IP地址等其他能够标识目标接入点的信息。其中，所述接入点标识信息可以通过用户设备读取接入点基站广播获得。

在具体实施中，基站可以根据接收到的上报信息，确定用户设备搜索到的目标接入点。基站可以根据目标接入点的标识信息，寻址到目标接入点。基站可以将用户设备的标识信息发送至目标接入点。目标接入点在接收到用户设备的标识信息后，可以判断该用户设备是否为签约用户，得到鉴权结果。基站可以通过核心网寻址到目标接入点基站，或者直接通过接入点标识寻址到目标接入点基站。
