基于 UE智能关联选取协作小区方法及协作用户设备 技术领域
本发明涉及通信技术领域， 具体是基于 UE (用户设备 )智能关联选取 协作小区方法及协作用户设备。 背景技术
在现有移动通信系统中， 小区间干扰是影响边缘吞吐量的主要原因， 而针对 LTE (长期演进）系统来说， 小区间的干扰尤显突出， 随着 ITU (国 际电信联盟 )为 IMT-Advanced (高级国际移动通信 )系统提出的性能指标， 3GPP (第三代移动通信合作伙伴项目 ）提出的 LTE- Advanced技术， 解决 小区干扰成为热门课题， 而在 LTE-Advanced 中引入 COMP ( Cooperative Multi-Point,多点协作）技术对于降低相邻小区干扰， 提高用户接收信号质 量具有里程碑意义。 COMP原理是使得在不同基站之间通过协同处理干扰， 或者避免干扰， 或者将干扰转化为有用信号， 从干扰处理的角度可以将 COMP分为两类： 一类是通过基站端进行合理的预编码使得信号在空间上 相互隔开， 或者通过协调调度， 让不同小区尽量在同一时间上避免调度同 一方向上的用户， 从而减少小区间的同频干扰， 保证用户的链路质量， 提 高解调性能， 这种技术称为协同调度 /协同波束赋形 （ Coordinate Schedule/Beamforming, CS/CB ); 另外一类是通过将其他小区的干扰信号转 化为本小区用户的有用信号， 通过提升用户的信噪比来保证解调性能， 这 种技术即称为联合处理 (Joint Processing , JP)。
在 COMP技术中， 所有的传输点之间协作能提供很大的小区边缘和平 均的小区吞吐量， 但是在所有的传输点之间共享数据 /CSI ( Channel State Indicator, 信道状态信息）需要很高的回传容量， 复杂度太高难于实现。 为 减小复杂度， 协作只能在有限数目的传输点之间为特定的 UE服务。 因此， 需要确定哪些传输点组成一个协作小区集合以及按照什么原则组成该协作 小区集合， 设计协作小区集合目标是在一个可接受的调度复杂度和回传容 量的前提下最大化小区吞吐量。
在 LTE— A (高级长期演进） 中引入 COMP传输技术后， 协作小区的选 取则是研究的关键点和热点。 目前针对网络侧来为协作用户选取协作集的 方法大体思想为：基于每个 UE 最强的干扰源而定。进行 COMP 的 UE 必 须测量及报告最强干扰集合给自己的服务小区， 根据一定门限值选择合适 数目的小区作协作小区集合。 根据用户向网络侧反馈的信息， 由网络侧进
1100 行行选选取取，， 一一般般根根据据 RRSSRRPP (( RReeffeerreennccee SSiiggnnaall RReecceeiivviinngg PPoowweerr,, 参参考考信信号号接接收收 功功率率）） 报报告告或或者者是是长长期期的的 CCSSII统统计计信信息息来来得得到到协协作作小小区区集集合合。。从从调调度度的的角角 度度看看，， 该该方方法法是是非非常常复复杂杂的的。。 另另一一方方面面，， CCOOMMPP用用户户需需要要测测量量周周围围比比较较多多 的的小小区区的的信信道道状状况况或或干干扰扰情情况况，， 向向网网络络侧侧反反馈馈量量比比较较大大，， 网网络络系系统统开开销销比比 较较大大，， 复复杂杂度度比比较较高高。。

为了使本发明的目的、 技术方案及优点更加清楚明白， 以下结合附图 及实施例， 对本发明进行进一步详细说明。 应当理解， 此处所描述的具体 实施例仅仅用以解释本发明， 并不用于限定本发明。
本发明实施例提供一种基于 UE 智能关联选取协作小区方法， 如图 1 所示， 该方法包括步驟：
步驟 S110、 协作用户接收服务小区收集并通过广播消息下发的该服务 小区所有相邻小区的负荷状态信息和相邻小区能支持业务的信息；
在该步驟 S110中， 服务小区收集所有相邻小区的负荷状态信息及相邻 小区能支持业务信息， 服务小区将收集到的相邻小区信息及自己的负荷信 息和能支持的业务信息通过广播消息发送给协作用户， 在 LTE 系统信息 SIB1 ( System Information Block Typel , 系 统信息块 1 ) 中 的 cell-AccessRelatedlnfo (小区接入相关信息）信息内添加负荷状态信息和能 支持业务类型及两者分别对应的加权系数字段。 同时也需要在同频邻区信 息 SIB4 ( System Information-Block Type4, 系统信息块 4 ) 中的 Intra Freq Neigh Cell Info (同频邻区信息）信息内增加负荷状态信息和能支持业务类 型两字段。 对于 COMP服务小区的系统广播下发仍按 LTE标准进行。
步驟 S120、 根据所述负荷状态信息和能支持业务信息对所述相邻小区 进行优先级排队， 并根据所述排队信息选取协作小区集；
在其他的实施例中， 更为具体的， 所述步驟 S120、 根据所述负荷状态 信息和能支持业务信息对所述相邻小区进行优先级排队。 如图 1所示， 具 体包括：
步驟 S121、 协作用户根据所述负荷状态信息和能支持业务信息采用加 权和的方法进行各相邻小区的优先级排队， 形成第一优先级队列。
在该步驟 S121中， 协作用户解析出各邻区的负荷和支持业务类型信息 后，协作用户采用加权和方法进行各邻区优先级排队， 以 PCI ( Phsyical Cell Identify, 物理小区标识） 为标识符进行区分， 优先级高者排在前面， 形成 第一优先级队列。 协作用户将该第一优先级队列緩存先緩存起来， 作为后 续协作用户选取协作小区选取的一个关联参数。
另外， 在其他的实施例中， 进一步的， 如图 2所示， 所述在步驟 S121 中形成第一优先级队列之后， 进一步包括步驟：
步驟 S122、 协作用户根据相邻小区列表对所有相邻小区进行测量， 通 过所述测量结果的 RSRP值和 CSI值对各相邻小区的信道质量进行评估， 并根据所述信道的质量采用加权和的方法对各相邻小区进行信道质量的排 队， 形成第二优先级队列。
在该步驟 S122中， 协作用户根据相邻小区列表对所有相邻小区进行测 量， 对测量结果 RSRP值和 CSI值进行各相邻小区信道质量进行评估， 可 采用加权和的方法进行相邻小区的信道质量排队， 质量好的排在前面， 形 成第二优先级队列， 同样可以用 PCI进行标识。
另外， 在其他的实施例中， 进一步的， 如图 2所示， 所述在步驟 S122 中形成第二优先级队列之后， 进一步包括步驟： 步驟 S123、 通过所述各相邻小区的信道质量、 所述负荷状态信息和能 支持业务信息， 在所述第一优先级队列和所述第二优先级队列的基础上进 行相同 PCI优先级求和的方法再次对个相邻小区进行优先级排队， 形成第 三优先级队列。
对于协作用户来说， 其已拥有各相邻小区信道质量状况信息， 同时也 拥有各相邻小区资源使用和负荷信息， 而且还拥有各相邻小区能支持的业 务类型信息， 针对拥有这些信息， 利用前面已有的第一优先级队列和第二 优先级队列进行相同 PCI优先级求和的方法， 再次对各相邻小区进行优先 级排队， 优先级高者排在前面， 形成第三优先级队列， 同样使用 PCI进行 标识。此时，协作用户可以根据自己在服务小区的 SINR值来确定协作小区 数目， SINR值越高， 所需的协作小区越少， 反之亦然。
步驟 S130、 向基站上报所述协作小区集信息。
在该步驟 S130中， 具体的， 通过新增信令来上报所述协作小区集信息 或者通过信令流程中的测量信令上报所述协作小区集信息。
另外， 在上述实施例中， 进一步的， 根据协作用户对协作小区集合数 目改变或者可以根据 UE选取的业务类型变化而需更新协作小区集来触发 步驟 S130的向基站上报所述协作小区集信息的过程。

应用实施例三：
图 7为协作用户选取业务改变更新协作小区集合交互图， 该过程是： 当协作用户选取的业务改变时， 例如需要特殊的 VIP业务， 由于协作小区 集中某些小区各种原因不支持该业务， 或者是该业务所需资源协作小区集 中某些小区不满足时， 协作用户需要更新协作小区集合， 此场景需要对业 务类型的加权值重新选择， 例如， 业务类型权值预定义为普通业务权值和 特殊业务权值， 经协作用户按上述应用实施例一方法重新选取协作小区集， 此方案更能选到满足协作用户特殊需求的协作小区集合。 协作小区集合需 要更新结果， 如： 源协作小区集为： #1、 #2、 #3 , 而由于某些原因， #2、 #3 不能满足该协作用户新业务的特殊需求， 所协作用户需重新选取协作小 区集合， 更新后的协作小区集为： #1、 #4、 #7。 该过程包括步驟：
