本申请要求于2021年12月17号申请的、申请号为202111551195.5的中国专利申请的优先权。
技术领域
本申请实施例涉及通信技术领域，特别涉及一种小区的干扰协调方法、装置、服务器和存储介质。
背景技术
如何高效使用频谱资源已成为目前移动无线网络领域的研究热点，一系列新兴技术也在持续涌现。其中，帧结构编排和动态频谱共享(Dynamic Spectrum Sharing，简称DSS)编排是其中的代表。帧结构编排是指在时分双工(Time Division Duplex，简称TDD)网络根据上下行负荷的占比动态调整上行帧和下行帧占比的技术。通过帧结构编排一方面可以动态适配上下行负荷的变化趋势，提升频谱资源使用效率；另一方面也可以提升用户体验。DSS编排是指小区在单一频谱上支持同时部署多种制式无线接入网络服务的DSS状态(比如3G/4G/5G DSS)，以及仅提供单一制式服务的状态(比如纯5G)，而小区实时状态则跟随各个制式用户实时负荷比例变化动态调整。利用DSS编排一方面可以动态适配不同制式业务的变化趋势，另一方面也可以通过消除DSS速率匹配的固定开销，从而显著提升频谱资源使用效率。
然而，对于帧结构编排来说，由于不同小区间上下行负荷比例可能存在显著差异，因此使能帧结构编排后，极大概率相干小区间帧结构无法对齐，如果同频邻区的下行子帧撞到本区上行子帧，则会对本区上行造成严重的干扰。对于DSS编排来说，由于不同小区间不同制式业务比例也可能存在显著差异，因此使能DSS编排后，极大概率相干小区间小区状态无法对齐。如果同频邻区处于4G/5G DSS状态，而本区处于纯5G状态，则同频相邻DSS 4G的小区参考信号(Cell Reference Signal，简称CRS)会对本区物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)造成严重的干扰。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施例中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的 前提下可以相互结合相互引用。
本申请的一个实施例涉及一种小区的干扰协调方法，应用在使用DSS编排方案的目标小区中，如图1所示，包括：
步骤101，获取目标小区在下一周期的策略信息表，策略信息表包含目标小区的第一周期优选策略和目标小区的各相干小区的第二周期优选策略。
在一示例实施中，任意一个基站小区均可以作为目标小区，目标小区的各相干小区是指和目标小区存在交叠覆盖的所有同频相邻小区，如图2所示，与基站小区40001在交叠覆盖的所有同频相邻小区为基站小区40003、基站小区40007和基站小区40009，因此当基站小区40001作为目标小区，其各相干小区为基站小区40003、基站小区40007和基站小区40009；同理，当基站小区40003作为目标小区，其各相干小区为基站小区40001；当基站小区40007作为目标小区，其各相干小区为基站小区40001、基站小区40009和基站小区40011；当基站小区40009作为目标小区，其各相干小区为基站小区40001和基站小区40007；当基站小区40011作为目标小区，其各相干小区为基站小区40007。
在一示例实施中，各目标小区的策略信息表由小区标识和小区的下一周期的周期可选策略组成，如图4所示，给出了各目标小区的策略信息表，在策略信息表中为了区分目标小区和各相干小区，可以将目标小区设置于第一位，也可以通过增加标识的方式，也可以直接根据各小区的小区标识来区分；其中，小区标识指为每个小区分配的独一无二的任意标识号，其初始化值即为系统分配的标识号；周期是提前设置好的，因此下一周期指未来最近一个周期，下一周期优选策略指每个小区基于其下一周期负荷预测和其它相关信息为下一周期选择的策略，其初始化值为预先定义好的所有小区均相同的默认策略。
在一示例实施中，第一周期优选策略和第二周期优选策略为纯5G状态(即5G)或4/5G共享状态(即4G/5G DSS)。
步骤102，根据第一周期优选策略和各第二周期优选策略获取目标小区的簇状态。
在一示例实施中，目标小区的簇状态是根据目标小区的第一周期优选策略和各相干小区的第二周期优选策略决定的；当第一周期优选策略与述第二周期优选策略均保持一致时，则认为目标小区的簇状态为簇内状态；而当第一周期优选策略与各第二周期优选策略存在不一致时，则认为目标小区的簇状态为非簇内状态。
在一示例实施中，如图3所示，目标小区与各相干小区在下一周期的周期优选策略一致时，表明目标小区与各相干小区在下一周期的处于相同工作环境和状态，此时，认为目标小区的簇状态为簇内状态；目标小区与各相干小区在下一周期的周期优选策略不一致时，表明目标小区与各相干小区在下一周期处于不同的工作环境和状态，此时，认为目标小区的簇状态为非簇内状态。
在一示例实施中，以图4所给出的目标小区的策略信息表为例：对于目标小区40001，由于相干小区40003的周期优选策略与目标小区40001的周期优选策略不一致，因此目标小区40001为非簇内状态；对于目标小区40003，由于相干小区40001的周期优选策略与目标小区40003的周期优选策略不一致，因此目标小区40003为非簇内状态；对于目标小区40007，由于相干小区40011的周期优选策略与目标小区40007的周期优选策略不一致，因此目标小区40007为非簇内状态；对于目标小区40009，由于各相干小区40001和40007的周期优选策略与目标小区40009的周期优选策略均保持一致，因此目标小区40009为簇内状态；对于 目标小区40011，由于相干小区40007的周期优选策略与目标小区40011的周期优选策略不一致，因此目标小区40011为非簇内状态。
步骤103，根据第一周期优选策略和簇状态确定目标小区在下一周期的干扰协调策略。
在一示例实施中，目标小区的第一周期优选策略为纯5G状态或4/5G共享状态，目标小区的簇状态为簇内状态或非簇内状态；干扰协调策略的确定规则如下：(1)簇状态为簇内状态且第一周期优选策略为纯5G状态时，干扰协调策略为不进行干扰协调；(2)簇状态为簇内状态且第一周期优选策略为4/5G共享状态时，干扰协调策略为自适应开关符号级速率匹配策略；(3)簇状态为非簇内状态且第一周期优选策略为纯5G状态时，干扰协调策略为自适应开关符号级速率匹配策略；(4)簇状态为非簇内状态且第一周期优选策略为4/5G共享状态时，干扰协调策略为自适应开关符号级速率匹配策略。
在一示例实施中，自适应开关符号级速率匹配策略，包括：根据各相干小区的4G小区参考信号干扰强度确定是否进行符号级速率匹配；根据目标小区在信道状态信息干扰测量资源(Channel State Information-Interference Measurement Resource，简称CSI-IM)上测量的各资源块的干扰情况，从各资源块选取目标资源块并进行调度。
在一示例实施中，以图4所给出的目标小区的策略信息表为例：目标小区40001为非簇内状态且第一周期优选策略为纯5G状态，目标小区40001干扰协调策略为自适应开关符号级速率匹配策略；目标小区40003为非簇内状态且第一周期优选策略为4/5G共享状态，目标小区40003干扰协调策略为自适应开关符号级速率匹配策略；目标小区40007为非簇内状态且第一周期优选策略为纯5G状态，目标小区40007干扰协调策略为自适应开关符号级速率匹配策略；目标小区40009为非簇内状态且第一周期优选策略为纯5G状态，目标小区40009干扰协调策略为不进行干扰协调；目标小区40011为非簇内状态且第一周期优选策略为4/5G共享状态，目标小区40011干扰协调策略为自适应开关符号级速率匹配策略。
在一示例实施中，目标小区在下一周期内所使能的优选策略为图4所示的各周期优选策略。
本实施例，在目标小区的干扰协调过程中，获取目标小区在下一周期的策略信息表，所述策略信息表包含所述目标小区的第一周期优选策略和所述目标小区的各相干小区的第二周期优选策略；根据所述第一周期优选策略和各所述第二周期优选策略获取所述目标小区的簇状态；根据所述第一周期优选策略和所述簇状态确定所述目标小区在下一周期的干扰协调策略。通过结合目标小区和各相干小区的下一周期优选策略来获取目标小区的簇状态，之后根据目标小区的簇状态和周期优选策略确定合适的干扰协调策略；能够在帧结构编排或DSS编排方案下实现自动、精准的小区间干扰协调，以消除/削弱相干小区间干扰对用户信道质量的影响；解决了由于帧结构编排导致的相干小区间帧结构无法对齐和DSS编排导致的相干小区间小区状态无法对齐引起的相干小区间干扰严重的技术问题。
本申请的一个实施例涉及一种小区的干扰协调方法，应用在使用帧结构编排方案的目标小区中，如图5所示，包括：
步骤201，获取目标小区在下一周期的策略信息表，策略信息表包含目标小区的第一周期优选策略和目标小区的各相干小区的第二周期优选策略。
在一示例实施中，本步骤与本申请实施例的步骤101大致相同，此处不一一赘述。唯一的区别在于，第一周期优选策略和第二周期优选策略为DDDSU帧结构或DSUUU帧结构， 其中，DDDSU帧结构是指基站小区采用30KHz子载波间隔和2.5ms单周期帧结构，每个周期5个slot分别为3个下行slot，1个特殊slot和1个上行slot；DSUUU帧结构是指基站小区采用30KHz子载波间隔和2.5ms单周期帧结构，每个周期5个slot分别为1个下行slot，1个特殊slot和3个上行slot。
步骤202，根据第一周期优选策略和各第二周期优选策略获取目标小区的簇状态。
在一示例实施中，当第一周期优选策略与各第二周期优选策略均保持一致时，则目标小区的簇状态为簇内状态；当第一周期优选策略与各第二周期优选策略存在不一致时，则目标小区的簇状态为非簇内状态。
在一示例实施中，以图6所给出的目标小区的策略信息表为例：对于目标小区40001，由于相干小区40003和40007的周期优选策略与目标小区40001的周期优选策略不一致，因此目标小区40001为非簇内状态；对于目标小区40003，由于相干小区40001的周期优选策略与目标小区40003的周期优选策略不一致，因此目标小区40003为非簇内状态；对于目标小区40007，由于相干小区40001和40009的周期优选策略与目标小区40007的周期优选策略不一致，因此目标小区40007为非簇内状态；对于目标小区40009，由于各相干小区40007的周期优选策略与目标小区40007的周期优选策略不一致，因此目标小区40009为非簇内状态；对于目标小区40011，由于相干小区40007的周期优选策略与目标小区40011的周期优选策略一致，因此目标小区40011为簇内状态。
步骤203，根据第一周期优选策略和簇状态确定目标小区在下一周期的干扰协调策略。
在一示例实施中，第一周期优选策略为DDDSU帧结构或DSUUU帧结构，簇状态为簇内状态或非簇内状态；干扰协调策略的确定规则如下：(1)簇状态为簇内状态且第一周期优选策略为DDDSU帧结构，干扰协调策略为不进行干扰协调；(2)簇状态为非簇内状态且第一周期优选策略为DDDSU帧结构时，干扰协调策略为结合各相干小区的协调开关位图进行协调；(3)簇状态为簇内状态且第一周期优选策略为DSUUU帧结构时，干扰协调策略为不进行干扰协调；(4)簇状态为非簇内状态且第一周期优选策略为DSUUU帧结构时，干扰协调策略为结合各所述相干小区的协调开关位图进行协调。
在一示例实施中，以图6所给出的目标小区的策略信息表为例：目标小区40001为非簇内状态且第一周期优选策略为DDDSU帧结构，目标小区40001干扰协调策略为结合各相干小区的协调开关位图进行协调；目标小区40003为非簇内状态且第一周期优选策略为DSUUU帧结构，目标小区40003干扰协调策略为结合各相干小区的协调开关位图进行协调；目标小区40007为非簇内状态且第一周期优选策略为DSUUU帧结构，目标小区40007干扰协调策略为结合各相干小区的协调开关位图进行协调；目标小区40009为非簇内状态且第一周期优选策略为DDDSU帧结构，目标小区40009干扰协调策略为结合各相干小区的协调开关位图进行协调；目标小区40011为簇内状态且第一周期优选策略为DSUUU帧结构，目标小区40011干扰协调策略为不进行干扰协调。
在一示例实施中，目标小区在下一周期内所使能的优选策略为图6所示的各周期优选策略。
本实施例，在目标小区的干扰协调过程中，获取目标小区在下一周期的策略信息表，所述策略信息表包含所述目标小区的第一周期优选策略和所述目标小区的各相干小区的第二周期优选策略；根据所述第一周期优选策略和各所述第二周期优选策略获取所述目标小区的簇 状态；根据所述第一周期优选策略和所述簇状态确定所述目标小区在下一周期的干扰协调策略。通过结合目标小区和各相干小区的下一周期优选策略来获取目标小区的簇状态，之后根据目标小区的簇状态和周期优选策略确定合适的干扰协调策略；能够在帧结构编排或DSS编排方案下实现自动、精准的小区间干扰协调，以消除/削弱相干小区间干扰对用户信道质量的影响；解决了由于帧结构编排导致的相干小区间帧结构无法对齐和DSS编排导致的相干小区间小区状态无法对齐引起的相干小区间干扰严重的技术问题。
本申请的一个实施例涉及一种小区的干扰协调方法，应用在使用帧结构编排方案或使用DSS编排方案的目标小区中，如图7所示，包括：
步骤301，对目标小区进行周期性负荷预测，基于目标小区的预测结果获取第一周期优选策略。
在一示例实施中，目标小区的负荷包含但不限于逻辑小区的上行/下行PRB利用率、RRC用户数，激活用户数等；对目标小区进行周期性负荷预测是基于目标小区的历史周期负荷数据进行的，本申请并不对所采用的具体预测算法进行限制，任意一种周期性负荷预测算法均可以使用。
在一示例实施中，当目标小区采用动态共享频谱编排方式时，目标小区的第一周期优选策略的生成规则包括：(1)预测结果为目标小区4G负荷轻且目标小区对应的基础小区4G负荷轻，第一周期优选策略为采用纯5G状态；(2)预测结果为目标小区4G负荷轻且目标小区对应的基础小区4G负荷重时，第一周期优选策略为采用4/5G共享状态；(3)预测结果为目标小区4G负荷重时，第一周期优选策略为采用4/5G共享状态；其中，目标小区对于的基础小区是指可以接纳目标小区4G业务的基站小区。
在一示例实施中，当目标小区采用帧结构编排方式时；目标小区的第一周期优选策略的生成规则包括：(1)预测结果为目标小区下行负荷重时，第一周期优选策略为采用DDDSU帧结构；(2)预测结果为目标小区上行负荷重时，第一周期优选策略为采用DSUUU帧结构。
在一示例实施中，由于目标小区自身也是其他基站小区的相干小区，因此，目标小区在获取到第一周期优选策略之后，需要向其他同频相邻小区进行广播，所广播的信息包含小区标识和对应的周期优选策略。
步骤302，接收各相干小区的广播信息，所述广播信息包含第二周期优选策略和相干小区标识。
在一示例实施中，各相干小区在获取到第二周期优选策略之后，会将第二周期优选策略和相干小区标识一同进行广播，目标小区可以接收到各相干小区的广播信息。
在一示例实施中，由于目标小区和各相干小区的周期都是一致的，因此，目标小区和各相干小区生成周期优选策略的时间也是一致的，目标小区可以在生成第一周期优选策略之后，在预设时间内接收各相干小区的广播信息，且在预设时间结束后开始更新初始化策略信息表。
步骤303，根据目标小区标识和各相干小区标识将第一周期优选策略和各第二周期优选策略填充至预设初始化策略信息表，生成策略信息表。
在一示例实施中，初始化策略信息表的格式与图3或图5的策略信息表的格式一致，只是初始化策略信息表中只包含有目标小区和各相干小区的小区标识，目标小区和各相干小区对应的周期优选策略为空，在获取到目标小区的第一周期优选策略和各相干小区的第二周期优选策略之后，根据目标小区标识和各相干小区标识将第一周期优选策略和各第二周期优选 策略填充至初始化策略信息表的对应位置，就可以形成目标小区的策略信息表；其中，如图8所示，初始化策略信息表中包含有目标小区的小区标识和各相干小区的小区标识，在初始化策略信息表中目标小区和各相干小区对应的周期优选策略可以为初始周期优选策略(4G/5G DSS或DDDSU)，也可以为空值。
步骤304，根据策略信息表中的第一周期优选策略和各第二周期优选策略获取目标小区的簇状态。
在一示例实施中，本步骤与本申请实施例的步骤102或步骤202大致相同，此处不一一赘述。
步骤305，根据第一周期优选策略和簇状态确定目标小区在下一周期的干扰协调策略。
在一示例实施中，本步骤与本申请实施例的步骤103或步骤203大致相同，此处不一一赘述。
本申请的实施方式，在其他实施例的基础之上还可以间隔周期对目标小区的策略信息表进行更新，使得确定的干扰协调策略能够与目标小区的业务情况保持一致，从而使得干扰协调策略的干扰协调能力达到最优。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本申请的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该申请的保护范围内。
本申请的另一个实施例涉及一种小区的干扰协调装置，应用在使用帧结构编排方案或使用DSS编排方案的目标小区中，下面对本实施例的小区的干扰协调装置的细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本例的必须，图9是本实施例所述的小区的干扰协调装置的示意图，包括：第一获取模块401、第二获取模块402和策略确定模块403。
其中，第一获取模块401，用于获取目标小区在下一周期的策略信息表，策略信息表包含目标小区的第一周期优选策略和目标小区的各相干小区的第二周期优选策略。
第二获取模块402，用于根据第一周期优选策略和各第二周期优选策略获取目标小区的簇状态。
策略确定模块403，用于基于预设干扰协调规则，根据第一周期优选策略和簇状态确定目标小区在下一周期的干扰协调策略。
不难发现，本实施例为与上述方法实施例对应的系统实施例，本实施例可以与上述方法实施例互相配合实施。上述实施例中提到的相关技术细节和技术效果在本实施例中依然有效，为了减少重复，这里不再赘述。相应地，本实施例中提到的相关技术细节也可应用在上述实施例中。
需要说明的是，本系统实施例主要是针对方法实施例提供的小区的干扰协调方法在软件实现层面上的描述，其实现还需要依托于硬件的支持，如相关模块的功能可以被部署到处理器上，以便处理器运行实现相应的功能，特别地，运行产生的相关数据可以被存储到存储器中以便后续检查和使用。
值得一提的是，本实施例中所涉及到的各模块均为逻辑模块，在实际应用中，一个逻辑单元可以是一个物理单元，也可以是一个物理单元的一部分，还可以以多个物理单元的组合 实现。此外，为了突出本申请的创新部分，本实施例中并没有将与解决本申请所提出的技术问题关系不太密切的单元引入，但这并不表明本实施例中不存在其它的单元。
本申请另一个实施例涉及一种服务器，如图10所示，包括：至少一个处理器501；以及，与所述至少一个处理器501通信连接的存储器502；其中，所述存储器502存储有可被所述至少一个处理器501执行的指令，所述指令被所述至少一个处理器501执行，以使所述至少一个处理器501能够执行上述各实施例中的小区的干扰协调方法。
其中，存储器和处理器采用总线方式连接，总线可以包括任意数量的互联的总线和桥，总线将一个或多个处理器和存储器的各种电路连接在一起。总线还可以将诸如外围设备、稳压器和功率管理电路等之类的各种其他电路连接在一起，这些都是本领域所公知的，因此，本文不再对其进行进一步描述。总线接口在总线和收发机之间提供接口。收发机可以是一个元件，也可以是多个元件，比如多个接收器和发送器，提供用于在传输介质上与各种其他装置通信的单元。经处理器处理的数据通过天线在无线介质上进行传输，进一步，天线还接收数据并将数据传送给处理器。
处理器负责管理总线和通常的处理，还可以提供各种功能，包括定时，外围接口，电压调节、电源管理以及其他控制功能。而存储器可以被用于存储处理器在执行操作时所使用的数据。
本申请另一个实施例涉及一种计算机可读存储介质，存储有计算机程序。计算机程序被处理器执行时实现上述方法实施例。
即，本领域技术人员可以理解，实现上述实施例方法中的全部或部分步骤是可以通过程序来指令相关的硬件来完成，该程序存储在一个存储介质中，包括若干指令用以使得一个设备(可以是单片机，芯片等)或处理器(processor)执行本申请各个实施例所述方法的全部或部分步骤。而前述的存储介质包括：U盘、移动硬盘、只读存储器(Read-Only Memory，简称ROM)、随机存取存储器(Random Access Memory，简称RAM)、磁碟或者光盘等各种可以存储程序代码的介质。
本领域的普通技术人员可以理解，上述各实施方式是实现本申请的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本申请的精神和范围。
