具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。下文中将结合附图对本申请的实施例进行详细说明。
分布式多输入多输出(Distributed Multiple-Input Multiple-Output，D-MIMO)、无蜂窝大规模多输入多输出(Cell-Free Massive Multiple-Input Multiple-Output，CF-MIMO)作为多天线方向的潜在关键技术得到了越来越多的关注。该技术的一个显著特征是在给定区域内AP的空间分布相较于新无线电(New Radio，NR)技术使用的集中式AP更分散，且AP的数目比较多，多个AP同时为多个不同UE服务。由于多个UE同时复用相同的时频资源，它们之间的干扰是不可避免的。
在未来CF-MIMO潜在的应用场景(如大型体育馆、商场、机场、自动化工厂)中，AP和UE的空间分布会十分复杂，可能会出现：部分区域AP或UE密集且数目多，部分区域AP或UE稀疏且数目少，部分区域AP或UE密度和 数目适中。因此，为UE确定服务AP、确定是否需要AP协作传输、确定AP协作传输规模等的方法在不同的场景下可能有不同的答案。
然而，目前在为UE确定服务AP时，主要是依据每个AP到特定UE的大尺度参数或者参考信号接收功率(Reference Signal Receiving Power，RSRP)参数，选择大尺度参数或者RSRP参数较大的某个/某些AP作为该特定UE的服务AP/服务AP集合。即相关技术中的方式往往只从接收信号的角度考虑，并没有考虑到干扰情况，也没有针对不同场景讨论是否需要AP协作，影响了UE的通信质量和通信系统的可靠性。
本申请提供的服务接入点的确定方法和信息发送方法可以应用于各类无线通信系统中，例如长期演进(long term evolution，LTE)系统、第五代移动通信技术(5th-generation，5G)系统、LTE与5G混合架构系统、5G NR系统、以及未来通信发展中出现的新的通信系统，如第六代移动通信技术(6th-generation，6G)系统等。图1示出了一实施例提供的一种无线通信系统的组网示意图。如图1所示，该无线通信系统包括终端设备110、接入网设备120和核心网设备130。
终端设备110可以是一种向用户提供语音/数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。一些终端设备110的举例为：UE、移动台、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-mobile Personal Computer，UMPC)、手持计算机、上网本、个人数字助理(Personal Digital Assistant，PDA)等可以联网的用户设备，或物联网中的物联网节点，或车联网中的车载通信装置，或娱乐、游戏设备或系统，或全球定位系统设备等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
接入网设备120是终端设备110通过无线方式接入到该无线通信系统中的接入设备，可以是AP，AP包括但不限于基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的下一代基站(next generation NodeB，gNB)、未来移动通信系统中的 基站或WiFi系统中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。本申请的实施例对接入网设备所采用的具体技术和具体设备形态不做限定。
核心网设备130可以包括接入与移动性管理网元和会话管理网元。示例性地，终端设备110可以通过接入网设备120接入核心网，从而实现数据传输。
在本申请实施例中，提供一种可运行于上述无线通信系统的服务接入点的确定、信息发送方法，通信节点及存储介质，能够在确定终端设备的服务AP的同时，降低终端设备之间的干扰，提升通信质量和通信系统的可靠性。
下面，对服务接入点的确定、信息发送方法，通信节点及其技术效果进行描述。
图2示出了一实施例提供的一种服务接入点的确定方法的流程示意图，如图2所示，本实施例提供的方法适用于接入网设备(如AP)或者核心网设备，该方法包括如下步骤。

步骤1、初始化候选AP集合、第一计数器和候选AP集合中每个AP的第二计数器。
步骤2、令第一计数器的计数值i＝1，并设置优先级顺序中的第i个终端设备为目标终端设备，根据第二指示信息、第三指示信息和服务AP确定准则，从候选AP集合中确定目标终端设备的服务AP。
步骤3、更新候选AP集合和第二计数器，并令第一计数器的计数值加1，且在i小于等于K时，返回执行设置优先级顺序中的第i个终端设备为目标终端设备，根据第二指示信息、第三指示信息和服务AP确定准则，从候选AP集合 中确定目标终端设备的服务AP的步骤，直至i大于K为止，K表示终端设备的数量，K为大于1的整数。
具体的，更新候选AP集合和第二计数器的方法可以包括：将服务AP的第二计数器的计数值加一；若服务AP的第二计数器的计数值小于服务AP的计数最大值，则保持候选AP集合不变；若服务AP的第二计数器的计数值等于服务AP的计数最大值，则停止服务AP的第二计数器计数，并从候选AP集合中去除服务AP。
示例性的，步骤1中初始化的候选AP集合为空间内所有AP的集合。假设初始候选AP集合内有M个AP，即初始候选AP集合为{1,2,K,M}，每个AP的第二计数器(又可以称为AP复用计数器)用于记录该AP同时服务的不同终端设备的数目，初始M个AP的第二计数器的计数值均为0。
在初次为终端设备确定服务AP时，按照优先级顺序将优先级顺序中的第1个终端设备设为目标终端设备，从候选AP集合中确定目标终端设备的服务AP。当确定AP i为目标终端设备的服务AP时，AP i的第二计数器加一。
在为目标终端设备确定完服务AP后，需要更新候选AP集合和第二计数器。候选AP集合是否需要更新取决于某个AP的第二计数器是否达到该服务AP的计数最大值。假设AP i最多同时服务不同终端设备的数目a max，i＝2，若AP i的第二计数器的计数值达到2，则AP i的第二计数器停止计数，并从候选AP集合中去除AP i；若AP i的第二计数器的计数值未达到2，则AP i的第二计数器继续工作，AP i继续保留在候选AP集合中。
随后，将优先级顺序中的下一个终端设备设为目标终端设备，再次从候选AP集合中确定目标终端设备的服务AP，直至为所有的终端设备确定完服务AP为止。具体的，在为终端设备确定服务AP时，在符合服务AP确定准则和第二参数集合Nc max的前提下，每个终端设备从候选AP集合中选择一个或多个AP为其服务。如果终端设备j的第二参数集合Nc max,j＝1，则在任何场景下，终端设 备j最多只能选到一个AP为它服务，无法进行协作传输；如果终端设备j的第二参数集合Nc max,j＝4，则是否有多个不同AP为终端设备j进行协作传输以及协作AP数目取决于候选AP集合的大小和服务AP确定准则。如果候选AP集合仅有一个元素，则终端设备j最多只能选到一个AP为它服务，无法进行协作传输；如果候选AP集合中有2-3个元素，则终端设备j是否有多个不同AP为其协作传输及协作传输规模取决于服务AP确定准则，但终端设备j不可能实现其配置的最多4个不同AP为其协作传输；如果候选AP集合中有不少于4个元素，则终端设备j是否有多个不同AP为其协作传输及协作传输规模取决于服务AP确定准则，终端设备j有可能实现其配置的最多4个不同AP为其协作传输。即终端设备j如果想要支持协作传输，需要保证其第二参数集合Nc max，j≥2，且候选AP集合中有不少于2个元素。
下面，罗列一些示例性实施方式，用于解释说明本申请实施例图2提供的服务接入点的确定方法，下述示例性实施方式可以单一执行，也可以组合执行。在下述示例性实施方式中，终端设备记为UE。
在第一个示例性实施方式中，图3示出了一实施例提供的一种服务接入点的确定示意图。

第二指示信息为UE的距离参数，第二指示信息为包括3个元素组的集合，即(D 1,D 2,D 3)，每个元素组D j包括7个元素(d 1j,d 2j,L,d ij,L,d 7j)。
第三指示信息包括第一参数集合a max＝1和第二参数集合Nc max＝4。
服务AP确定准则为d Ωj∈[r 1,r 2]，0＜r 1＜r 2，Ω为候选AP集合，j为1到3之间的整数，Ω中的元素为1到7之间的整数。
根据第一指示信息，按照UE的业务量要求的取值进行降序排列，则UE的 优先级顺序从高到低依次为UE 1、UE 2、UE 3。
候选AP集合初始值为Ω 0＝{1,2,3,4,5,6,7}，候选AP集合中每个AP的第二计数器的初始值N＝{0,0,0,0,0,0,0}。
由于UE 1具有最高优先级，首先确定UE 1的服务AP。根据UE的距离参数、候选AP集合Ω 0、第一参数集合a max＝1、第二参数集合Nc max＝4和服务AP确定准则为
Figure PCTCN2022131642-appb-000008
j＝1，最终确定UE 1的服务AP集合Ω U1＝{1,3,4,6}。
第一次更新后的候选AP集合中每个AP的第二计数器的计数值为N＝{1,0,1,1,0,1,0}，由于AP最多同时服务不同UE的数目的第一参数集合a max＝1，UE 1的服务AP集合Ω U1对应的AP的第二计数器停止计数，需要将UE 1的服务AP集合Ω U1中的AP从初始候选AP集合Ω 0中移除，得到第一次更新后的候选AP集合Ω 1＝{2,5,7}。
UE 2具有次高优先级，其次确定UE 2的服务AP。根据UE的距离参数、候选AP集合Ω 1、第一参数集合a max、第二参数集合Nc max和服务AP确定准则为d Ω1j∈[r 1,r 2]，j＝2，最终确定UE 2的服务AP集合Ω U2＝{2,5}。
第二次更新后的候选AP集合中每个AP的第二计数器的计数值为N＝{1,1,1,1,1,1,0}，由于AP最多同时服务不同UE的数目的第一参数集合a max＝1，UE 2的服务AP集合Ω U2对应的AP的第二计数器停止计数，需要将UE 2的服务AP集合Ω U2中的AP从候选AP集合Ω 1中移除，得到第二次更新后的候选AP集合Ω 2＝{7}。
UE 3具有最低优先级，最后确定UE 3的服务AP。根据UE的距离参数、候选AP集合Ω 2、第一参数集合a max、第二参数集合Nc max和服务AP确定准则为
Figure PCTCN2022131642-appb-000009
j＝3，最终确定UE 3的服务AP集合Ω U3＝{7}。
UE 1、UE 2、UE 3都确定了服务AP后，结束循环过程。UE 1、UE 2、UE  3的服务AP集合分别为Ω U1＝{1,3,4,6}、Ω U2＝{2,5}、Ω U3＝{7}。虽然UE最大协作AP的数目的第二参数集合Nc max＝4，但只有UE 1达到了配置最大不同协作AP的数目，UE 3无法进行协作传输，只有AP 7为其服务。如果只考虑服务AP确定准则，d 42∈[r 1,r 2]，d 43∈[r 1,r 2]，那么AP 4就可以为UE 2或UE 3服务，但由于约定的AP最多只能为一个UE服务，UE 1确定服务AP后，AP 4从候选AP集合中删除，那么在UE 2或UE 3确定服务AP的时候，候选AP集合中已经没有AP 4，也就无法选到AP 4为其服务。即本申请在UE的优先级顺序、第一参数集合a max、第二参数集合Nc max，候选AP集合和服务AP确定准则等因素的共同作用下确定所有UE的服务AP集合。

j＝3，最终确定UE 3的服务AP集合Ω U3＝{4,5,7}。
第二次更新后的候选AP集合中每个AP的第二计数器的计数值为N＝{1,0,1,2,1,1,1}，由于AP最多同时服务不同UE的数目的第一参数集合a max＝2，AP 4的第二计数器的计数值达到计数最大值，AP 4的第二计数器停止计数，其余AP的第二计数器的计数值未达到计数最大值，因此其余AP的第二计数器继续计数。AP 4从候选AP集合Ω 1中移除，其余AP继续保留在候选AP集合Ω 1中，得到第二次更新后的候选AP集合Ω 2＝{1,2,3,5,6,7}。

j＝2，最终确定UE 2的服务AP集合Ω U2＝{2,5}。
第三次更新后的候选AP集合中每个AP的第二计数器的计数值为N＝{1,1,1,2,2,1,1}，由于AP最多同时服务不同UE的数目的第一参数集合a max＝2，AP 5的第二计数器的计数值达到计数最大值，AP 5的第二计数器停止计数，其余AP的第二计数器的计数值未达到计数最大值，因此其余AP的第二计数器继续计数。AP 5从候选AP集合Ω 2中移除，其余AP继续保留在候选AP集合Ω 2中，得到第三次更新后的候选AP集合Ω 3＝{1,2,3,6,7}。
UE 4具有最低优先级，最后确定UE 4的服务AP。根据UE的大尺度参数、候选AP集合Ω 3、第一参数集合a max、第二参数集合Nc max和服务AP确定准则为
Figure PCTCN2022131642-appb-000014
j＝4，最终确定UE 4的服务AP集合Ω U4＝{7}。
UE 1、UE 2、UE 3、UE 4都确定了服务AP后，结束循环过程。UE 1、UE2、UE 3、UE 4的服务AP集合分别为Ω U1＝{1,3,4,6}、Ω U2＝{2,5}、Ω U3＝{4,5,7}、Ω U4＝{7}。虽然UE最大协作AP的数目的第二参数集合Nc max＝4，但只有UE 1达到了配置最大不同协作AP的数目，UE 4无法进行协作传输，只有AP 7为其服务。在UE 1确定其服务AP后，随后UE 3开始确定其服务AP，尽管设定的AP最多同时服务不同UE的数目的第一参数集合a max＝2，第一次更新后的候选AP集合Ω 1＝{1,2,3,4,5,6,7}，AP 1、AP 2、AP 3、AP 4、AP 5、AP 6、AP7都有可能为UE 3服务，但只有AP 4、AP 5、AP7满足服务AP确定准则。当UE 2确定服务AP时，候选AP集合Ω 2＝{1,2,3,5,6,7}，但只有AP 2、AP 5满足服务AP确定准则。即本申请在UE的优先级顺序、第一参数集合a max、第二参数集合Nc max，候选AP集合和服务AP确定准则等因素的共同作用下确定所有UE的服务AP 集合。
在第三个示例性实施方式中，图5示出了一实施例提供的又一种服务接入点的确定示意图。

服务AP确定准则为RP Ωj∈[RP min,RP max]，Ω为候选AP集合，j为1到3之间的整数，Ω中的元素为1到7之间的整数。

第一次更新后的候选AP集合中每个AP的第二计数器的计数值为N＝{0,1,0,1,0,0,0}，由于AP最多同时服务不同UE的数目的第一参数集合a max＝2，UE 2的服务AP集合Ω U2对应的AP的第二计数器的计数值未达到计数最大值，所有AP的第二计数器继续计数，UE 2的服务AP集合Ω U2对应的AP继续保留在初始候选AP集合Ω 0中，候选AP集合中元素没有变化，得到第一次更新后的候选AP集合Ω 1＝{1,2,3,4,5,6,7}。
UE 1具有次高优先级，其次确定UE 1的服务AP。根据UE的RSRP参数， 候选AP集合Ω 1、第一参数集合a max、第二参数集合Nc max和服务AP确定准则RP Ω1j∈[RP min,RP max]，j＝1，最终确定UE 1的服务AP集合Ω U1＝{1,3}。

第二参数集合Nc max用于限制终端设备协作集规模，不同的终端设备可以有 不同的配置。例如，第二参数集合Nc max中仅有一个元素表示所有终端设备最大协作AP的数目均相同；又例如，第二参数集合Nc max中包括K个元素，则K个元素中部分元素的值不同或者所有元素的值都不相同，即部分终端设备最大协作AP的数目不同或者所有终端设备最大协作AP的数目完全不同。
