Description

无线通信方法和设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及无线通信方法和设备。
背景技术
在长期演进(Long Term Evolution，LTE)中，覆盖和容量优化(Coverage and Capacity Optimization，CCO)通过调整小区天线的角度、功率等发射参数以提升网络的覆盖和容量性能。例如，如果一个热点区域位于靠近小区边界的位置，那么小区之间的干扰会加大，进而影响无线资源的使用效率和容量。基于此，热点区域所在小区需要将本小区的覆盖范围进行调整。相应的，邻小区在接收到热点区域所在小区调整覆盖范围的信息后，也需要对小区的覆盖范围进行调整。
但是，LTE中的CCO需要引用专门的操作管理维护(Operation Administration and Maintenance，OAM)设备，增加了优化成本。此外，由于五代移动通信技术(5-Generation，5G)引入了波束赋形技术，其小区覆盖形态比LTE会更加灵活，LTE中的CCO也不适用于5G场景。
发明内容
提供了一种无线通信方法和设备，不仅能够降低CCO的优化成本，还可适用不同的通信场景，以提升CCO的可应用性。

第四方面，提供了一种接入网设备，用于执行上述第二方面或其各实现方式中的方法。具体地，所述接入网设备包括用于执行上述第二方面或其各实现方式中的方法的功能模块。
第五方面，提供了一种接入网设备，包括处理器和存储器。所述存储器用于存储计算机程序，所述处理器用于调用并运行所述存储器中存储的计算机程序，以执行上述第一方面或其各实现方式中的方法。

第七方面，提供了一种芯片，用于实现上述第一方面至第二方面中的任一方面或其各实现方式中的方法。具体地，所述芯片包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有所述芯片的设备执行如上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第八方面，提供了一种计算机可读存储介质，用于存储计算机程序，所述计算机程序使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第九方面，提供了一种计算机程序产品，包括计算机程序指令，所述计算机程序指令使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
第十方面，提供了一种计算机程序，当其在计算机上运行时，使得计算机执行上述第一方面至第二方面中的任一方面或其各实现方式中的方法。
基于以上技术方案，第一接入网设备通过以下接口中的至少一项，向第二接入网设备发送包括覆盖修改列表的第一消息：Xn接口、NG接口以及S1接口，相当于，所述第一接入网设备和所述第二接入网设备可以直接交互所述第一消息或通过核心网设备交互所述第一消息，不仅能够避免引入专门用于传输所述第一消息的管理设备，以降低CCO的优化成本，还可适用不同的通信场景，以支持系统内的CCO以及系统间的CCO，相应的，能够提升CCO的可应用性。

在本申请的一些实施例中，所述第一类型包括高覆盖类型、中覆盖类型以及低覆盖类型中的至少一项。
例如，所述至少一个信息中的任一信息通过高覆盖类型指示所述任一信息对应的SSB的状态为激活态和/或指示所述任一信息对应的SSB的覆盖配置。
换言之，所述至少一个信息中的任一信息通过高覆盖类型、中覆盖类型以及低覆盖类型中的至少一项指示所述任一信息对应的SSB的覆盖配置，此时，默认所述任一信息对应的SSB的状态为激活态。
在本申请的一些实施例中，所述第一小区的标识为演进的通用陆地无线接入网络小区全局标识(E-UTRAN Cell Global Identifier，ECGI)，或所述第一小区的标识为新空口小区全局标识(New Radio Cell Global Identifier，NCGI)。
图3是本申请实施例提供的基于CCO修改SSB的覆盖范围的示意图。
如图3所示，所述第一接入网设备确定需要修改覆盖范围的小区对应三个SSB，即SSB1、SSB2以及SSB3，且仅修改SSB3的覆盖范围。所述第一接入网设备发送给所述第二接入网设备的所述第一消息可以仅包括SSB3的标识和所述SSB3的覆盖配置，以便所述第二接入网设备基于所述第一消息中的SSB3的标识和所述SSB3的覆盖配置，修改 与所述SSB3方向相反的SSB的覆盖范围。
换言之，所述第一消息可以仅包括需要修改覆盖范围的小区所对应的需要调整覆盖范围的至少一个SSB的标识，即仅修改所述至少一个SSB的覆盖范围，避免了修改小区的覆盖范围。
换言之，所述第一接入网设备可以不将小区的覆盖范围告知给所述第二接入网设备，而是选择将小区里的某(几)个SSB的覆盖范围的改动告知给所述第二接入网设备。
需要说明的是，在5G NR中，由于对于部署频率更高的考虑，为了扩大覆盖范围，包含解调参考信号(Demodulation Reference Signal，DMRS)和包含主同步、辅同步和MIB的SSB不再是全向发送，而是在每个时刻都朝向某一方向发射。例如，可以隔一段时间在某一个半帧内发送若干个SSB，以便对端进行波束扫描。例如，所述若干个SSB中每个都对应一个波束扫描方向，最终每个方向都会有一个SSB，所述若干个SSB也可称为一个SSB组(set)。换言之，所述一个SSB set中的所有SSB在同一个半帧内。可选的，所述SSB set的周期可以是5、10、20、40、80、160ms。可选的，可以在SIB1中指示所述SSB set的周期。可选的，在初始小区搜索的时候，即终端设备还没有收到SIB1的情况下，所述终端设备可以按照默认20ms的周期搜索SSB。可选的，不同方向的SSB可以对应不同的SSB编号(SSB-index)。
基于此，可以发现，每个SSB的覆盖范围不但能够决定控制面信令的覆盖范围，也能够决定数据信道的覆盖范围。因此，在本申请实施例中，通过修改SSB的覆盖范围，能够细化CCO的优化粒度，相应的，能够提升CCO的优化效果。
在本申请的一些实施例中，所述第一接入网设备所属的通信系统和所述第二接入网设备所属的通信系统为同一通信系统。例如，所述第一接入网设备和所述第二接入网设备均连接到同一个核心网网元。作为本申请的示例，所述第一接入网设备和所述第二接入网设备之间支持Xn接口或不支持Xn接口。

由于所述第一接入网设备和所述第二接入网设备均可以为ng-eNB或者gNB，因此，所述覆盖修改列表中需要提供所述第一接入网设备的小区的小区ID，即E-UTRAN小区全局标识(E-UTRAN Cell Global Identifier，ECGI)或新空口小区全局标识(New Radio Cell Global Identifier，NCGI)。针对ECGI，所述覆盖修改列表可以包括以下中的至少一项：需要调整覆盖范围的第一小区的标识、用于指示所述第一小区的覆盖状态的信息、用于指示下次重配置时是否应用小区部署状态的信息以及替代小区的标识。针对NGCI，所述覆盖修改列表可以包括所有SSB的覆盖状态指示或者至少包括需要修改的SSB的覆盖状态指示和相应的SSB索引号。
当然，若所述第一接入网设备所属的通信系统和所述第二接入网设备所属的通信系统为同一通信系统，所述第一接入网设备也可通过所述NG接口或S1接口向所述第二接入网设备发送所述第一消息。例如，若所述第一接入网设备和所述第二接入网设备均连接到同一个核心网网元，且所述第一接入网设备和所述第二接入网设备之间不支持Xn接口，所述第一接入网设备也可以通过所述NG接口或S1接口向所述第二接入网设备发送所述第一消息。

由于所述第一接入网设备和所述第二接入网设备均可以为ng-eNB或者gNB，因此，所述覆盖修改列表中需要提供所述第一接入网设备的小区的小区ID，即E-UTRAN小区全局标识(E-UTRAN Cell Global Identifier，ECGI)或新空口小区全局标识(New Radio Cell Global Identifier，NCGI)。针对ECGI，所述覆盖修改列表可以包括以下中的至少一项：需要调整覆盖范围的第一小区的标识、用于指示所述第一小区的覆盖状态的信息、用于指示下次重配置时是否应用小区部署状态的信息以及替代小区的标识。针对NGCI，所述覆盖修改列表可以包括所有SSB的覆盖状态指示或者至少包括需要修改的SSB的覆盖状态指示和相应的SSB索引号。
