具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”和“第二”等是用于区别不同的对象，而不是用于描述特定的顺序。此外术语“包括”和“具有”以及他们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有设定于已列出的步骤或单元，而是可包括没有列出的步骤或单元。
本发明实施例提供了一种信道质量调整方法，参见图1，该方法可以包括以下步骤：
S101、依据用户的特征信息对小区内用户进行划分，获得用户簇。
因为现有技术中针对突发模式的业务场景下进行匹配信道变化，主要采用的方法是加大外环调整量的调整步长。由于单个用户上看业务仍然是不连续的，调度间隔仍然较长。本发明实施例利用具有较高信道相关性的用户组成用户簇，可以通过用户簇的簇级外环量，弥补用户级外环量的不足。
其中，根据用户的特征信息对用户进行划分时，这些特征信息主要包括了用户的信道质量、干扰特征及用户间相关性等条件。在划分得到用户簇后，需要对用户进行相应的出簇和入簇管理，实时保证各个用户簇内的用户的特征信息最为相关。
当对用户进行簇管理时，主要包括：
若第一用户在目标用户簇中且所述第一用户满足出簇条件，则对所述第一用户进行出簇管理；
若第二用户不在目标用户簇中且所述第二用户满足入簇条件，则对所述第二用户进行入簇管理。
S102、计算获得所述用户簇的信道质量簇外环调整量。
在确定簇外环调整量时，需要先确定用户簇内用户维护的外环量中的最大值和最小值，从而可以根据该最大值和最小值来确定簇外环调整量，具体包括：
获取所述用户簇内用户维护的外环量中的最大值和最小值；
若所述用户簇外环量超过所述最大值，则将所述用户簇的信道质量簇外环调整量确定为所述最大值；
若所述用户簇外环量小于所述最小值，则将所述用户簇的信道质量簇外环调整量确定为所述最小值；
若所述用户簇外环量大于所述最小值且小于所述最大值，则将所述根据用户初传的传输块的数据信息，计算获得用户簇的信道质量簇外环调整量。
在现有用户级CQI外环调整量基础上，增加簇级CQI外环调整量，区分单流外环和双流码字0及码字1外环量。簇外环量的初始值为0，在计算获得用户簇的信道质量簇外环调整量时，计算方式如下：
(1)当同一个TTI(Transmission Time Interval，发送时间间隔)，收到用户簇内用户初传TB(Transport Block，传输块)反馈都为ACK(当簇内用户为RANK2时，指针对每个码块反馈)时：
若为RANK1，则簇单流外环统计量＝簇单流外环统计量+0.1/9；
若为RANK2码字0，则簇码字0外环统计量＝簇码字0外环统计量+0.1/9；
若为RANK2码字1，则簇码字1外环统计量＝簇码字1外环统计量+0.1/9；
其中，将对一个或两个码字分别进行扰码(Scrambling)和调制(Modulation)之后得到的复数符号根据层映射矩阵映射到一个或多个传输层。层映射矩阵的维数为C×R，C为码字的个数，R为阶(Rank)，也就是使用的传输层的个数。ACK：表示UE(UserEquipment，用户设备)正确解调下行数据，指示基站可以在相应HARQ(混合自动重传请求，hybrid automatic repeat request)进程上进行初传。
(2)当同一个TTI，收到簇内用户初传TB反馈包含NACK(当簇内用户为RANK2时，指针对每个码块反馈)时，NACK表示UE解调下行数据错误，指示基站在相应HARQ进程上重传相关数据，计算方式为：
若为RANK1，则簇单流外环统计量＝簇单流外环统计量-0.1；
若为RANK2码字0，则簇码字0外环统计量＝簇码字0外环统计量-0.1；
若为RANK2码字1，则簇码字1外环统计量＝簇码字1外环统计量-0.1。
需要说明的是，增加簇级CQI外环调整量后，每个用户的CQI外环调整量仍然正常维护。并且为了保证调整量的准确性，需要确定簇外环调整量的时效性。当簇外环量在设定时间范围未更新，则簇外环量重新初始化为0。
S103、当用户的信道质量外环失效时，将所述用户归属的用户簇对应的簇外环调整量，确定为所述用户的信道质量外环的初始值；
S104、通过所述初始值对所述用户的信道质量进行调整。
簇外环量主要应用于簇内用户自身维护的外环量无效时，该用户的外环量初始值可以使用所在簇的外环量，这样可以加速用户IBLER收敛。在下行AMC(AdaptiveModeCode，自适应调制编码)模块中，当计算用户调整后CQI时，若当前用户维护的外环量失效(例如，用户为RANK1，则指单流外环失效，用户为RANK2，指任意一个码字外环量失效)，则使用有效的簇外环量作为外环初始值，在此基础上进行用户级外环量统计，从而实现对信道质量的调整。若用户维护的外环量和簇级外环量都失效，则统一使用初始化值为0。
本发明提供的信道质量调整方法，根据用户的特征信息进行划分得到用户簇，通过计算获得用户簇的信道质量簇外环调整量，可以在用户的信道质量外环失效时，使得用户簇内的用户通过将用户簇的簇外环调整量作为初始值进行信道质量调整，可以弥补用户级外环量的不足，使得对信道质量的调整能更快匹配信道变化，促使用户的初传误块率快速收敛，提升系统频谱效率。
参见图2，为本发明实施例提供的一种网络架构图，包括用户设备(UE)和基站(ENB)。
在UE侧：
UE根据A3测量配置上报测量报告，该测量报告中包含服务小区和干扰邻区信息，其中，A3测量是指UE测量服务和干扰邻区RSRP(ReferenceSignalReceivingPower，参考信号接收功率)，当二者的差值在设定的门限范围内时，UE就能触发A3上报，按设定的周期进行上报。
UE周期性测量CQI及RI(RankIndication，Rank指示)并上报；
UE反馈ACK/NACK信息，其中，ACK表示UE正确解调下行数据，指示基站可以在相应HARQ(混合自动重传请求，hybrid automatic repeat request)进程上进行初传；NACK表示UE解调下行数据错误，指示基站在相应HARQ进程上重传相关数据。
UE周期性上报SRS(Sounding Reference Signal，Sounding参考信号)信息，其中，SRS就是UE按照配置的SRS周期和带宽，发送特定的序列信息，基站根据接收的信息，可以进行用户上行信道估计。
UE会将上述信息发送至ENB，其中，ENB需要分层处理，在进行用户簇划分时，也是根据UE向ENB发送的信息进行划分的，具体的包括：
当用户将测量报告和序列信息发送至基站时，通过基站对所述测量报告进行滤波处理，获得所述用户对应小区的滤波后的参考信号接收功率，其中，所述测量报告包括用户测量服务和干扰邻区的参考信号接收功率；
通过所述基站对序列信息进行信道估计，计算获得用户间的相关性系数；
根据所述滤波后的参考信号接收功率和所述用户间的相关性系数，对小区内的用户进行划分，获得用户簇。
当ENB分为三层进行处理时，参见图2，具体的ENB侧处理为：
1)层3接收到UE上报的A3测量报告，则分别对上报的每个小区RSRP值进行滤波，保存，同时将处理后的结果发给层2；
2)层1接收到用户上报的SRS信息后，进行信道估计，同时计算该用户与小区内其他用户间的相关性，相关性系数计算公式如下：
Figure PCTCN2019083365-appb-000001
其中，H 1、H 2分别表示两个用户估计的信道，||||表示求模，·表示内积，Re表示取复数的实部。该值越大，表示相关性越高，两个信道就越相似，反之，表示相关性越低。相关性越高，用户解调性能越相近(即用户反馈ACK/NACK的概率是相差不多的)；
3)层2接收到层1转发接收到UE上报的CQI后，进行CQI滤波保存；
4)层2一旦接收到上述全部或部分信息后，会触发进行用户簇管理；
5)若簇内有用户上报ACK/NACK，则进行簇外环调整量更新；
6)层2对当前调度优先级队列中有业务数据需要调度的连接进行调度。
在本发明实施例中提供了一种入簇管理方法，包括：
判断所述第二用户是否将测量报告发送到基站，且所述第二用户存在所述测量报告对应的邻区，如果是，则在当前小区栅格化信道质量用户簇中确簇的最强干扰邻区与所述第二用户的最强干扰邻区相同的目标用户簇；
若存在所述目标用户簇，则判断第二用户与所述目标用户簇内用户的信道质量指示值的最大与最小值之间的差值对应的绝对值是否满足设定门限值，若满足，则计算获得第二用户与所述目标用户簇中用户的相关性系数；
若所述相关性系数满足预设门限阈值，则将所述第二用户加入到所述目标用户簇中。
具体的，参见图3，在本发明中还提供了另一种入簇管理的实施方式，包括：
S301、判断用户A有A3上报且存在A3邻区，若是执行S303，若否则执行302；
S302、轮询完小区栅格化CQI簇，是则结束，否则取出一个簇B，执行S305；
S303、从当前小区栅格化CQI簇中找出簇的最强干扰邻区与用户A的最强干扰邻区相同的簇CLA，若存在，则执行S304，否则用户A单独组簇；
S304、轮询完CLA，是则结束，否则，取出一个簇C，执行S305；
S305、用户A是否有CQI上报，是则执行S306，否则用户A单独组簇；
S306、判断用户A与选出簇内用户CQI值的最大与最小值之间差值的绝对值是否小于等于设定门限DeltCqiTh，同时RI也与簇内用户相等，是则执行S307，否则跳转至步骤S302或者S304；
S307、判断用户A是否有相关性上报且与选出簇内每个用户间的相关性大于等于设定门限CorrTh(默认0.5)，是则执行S308，否则跳转至步骤S302或者S304；
S308、将用户A加入所选出簇中，结束。
对应的，出簇管理的触发条件包括：用户上报A3，用户上报CQI，相关性上报，任意一条上报都会触发该操作，具体的，在本发明实施例中提供了一种出簇管理方法，包括：
判断第一用户是否将测量报告发送至基站，如果是，判断所述第一用户最强干扰邻区与所述第一用户当前所在目标用户簇的最强干扰邻区是否相同；
若所述第一用户的最强干扰邻区与目标用户簇的最强干扰邻区不同，则将所述第一用户从所述目标用户簇中删除，并设置所述第一用户的标识为用户无簇标识；
若所述第一用户的最强干扰邻区与目标用户簇的最强干扰邻区相同或者所述第一用户未将测量报告发送至基站，则判断所述第一用户发送至基站的信道质量指示滤波值与目标用户簇内其他用户的信道质量指示滤波值的差值绝对值，是否不大于预设门限值；
若所述差值绝对值大于预设门限值，则将所述第一用户从所述目标用户簇中删除，并设置所述第一用户的标识为用户无簇标识；
或者，若所述用户与簇内其他用户的相关性不大于预设门限值时，将所述用户从对应的目标用户簇中删除，并设置所述用户的标识为用户无簇标识。
参见图4，为出簇管理的具体实施方式的方法流程示意图，包括：
S401、若用户有A3上报，则执行S402，否则执行S403；
S402、若用户最强干扰邻区与用户当前所在簇的最强干扰邻区不同，则执行S405，否则执行S403；
S403、若用户上报CQI滤波值与簇内其他用户的CQI滤波值的差值绝对值小于等于设定门限，则执行S404，否则执行S405；
S404、若用户与簇内其他用户的相关性小于等于设定门限，则结束，否则执行S405；
S405、将用户从簇中删除，标识用户无簇，同时可以对该用户进行入簇管理。
参见图5，为本发明实施例提供的另一种信道质量调整方法的流程示意图，包括网络参数配置实体、UE和ENB。
首先通过网络参数配置实体，将簇级调整特性开关和簇级参数配置下发给网络内的各ENB。
ENB将需要UE提供的测量信息通过配置消息通知UE，UE将测量结果上报给服务ENB，在接收到UE测量结果后，启动簇管理和簇级外环调整量维护。
本发明利用小区内具有相似信道特征的用户组成簇，簇内用户共享簇级外环调整量，每个用户反馈的ACK/NACK在修正用户级外环调整量时，同时修正簇级外环调整量。对于簇内用户，若用户级外环调整量失效，可以采用簇级外环调整量替代用户级外环调整量初值。在本发明实施例中引入簇级CQI外环调整量，簇内用户调度MCS(Modulation and Coding Scheme，调制与编码策略)能更快匹配信道变化，用户IBLER能更快收敛到设定的目标值；引入簇级CQI外环调整量，能有效提升系统频谱效率和小区吞吐率。
