Description

一种无线通信方法、 设备及系统
本申请要求于 2012 年 11 月 21 日提交中国专利局、 申请号为 201210475452.6、 发明名称为"无线通信方法、 设备及系统"的中国专利申请的 优先权， 其全部内容通过引用结合在本申请中。 技术领域
本申请涉及蜂窝通信技术领域，具体涉及一种无线通信方法、设备及系统。 背景技术
目前的移动通信系统均采用蜂窝系统，基于蜂窝通信架构来实现，蜂窝通 信架构是现在移动通信中一种代表性的通信架构，如同一个蜂窝网，每一个网 格由多个小区进行组合构建。 蜂窝系统是以网络为中心进行通信资源的调度， 每个小区都是独立的通信调度资源。
目前蜂窝技术已发展到先进的长期演进（ Long Term Evolution Advanced, 筒称 LTE-A或者 LTE ) 的水平， 在 LTE系统中， 这种以网络为中心的蜂窝系 统依旧存在小区边缘通信性能差的问题， 不仅小区边缘用户的吞吐量很低， 而 且当用户设备在移动过程中需要切换与小区之间的通信链路时，如果采用硬切 换机制先中断与原小区的通信链路，再与目标小区建立通信链路会致使切换过 程中产生链路缝隙， 出现 "掉话"现象； 如果采用切换机制先与目标小区建立 通信链路， 再中断与原小区的通信链路， 即使可以避免产生链路缝隙， 但相对 于硬切换机制会占用更多的信道资源，增加蜂窝系统的工作负荷。 以及由于用 户设备在网络中的分布是随机的、 时变的，通常情况下有些小区驻留大量用户 设备， 而有些小区内的用户设备很少， 导致网络负载能力分布不均衡。
虽然通过多点协作 (Coordinated Multiple Point, CoMP)技术提高了小区边 缘频谱效率， 但是在形成的协作集边缘上， 通信性能较差， 且不同的协作方式 受回程链路条件和信道状态信息反馈的影响，只能实现协作区域的半静态配置 以及小范围内的协作，只能通过同一小区或者同一协作集内的小区进行链路通 信， 通信链路的建立自由度受限。 且仍然存在网络负载能力分布不均衡、 负载 切换机制不健全等诸多问题。 发明内容

为了使本发明所要解决的技术问题、 技术方案及有益效果更加清楚明白， 以下结合附图及实施例， 对本发明进行进一步详细说明。
本申请第一实施例提供了一种无线通信方法， 是基于蜂窝通信架构实现， 其中， 蜂窝通信架构是现在移动通信的一种代表性架构， 请参阅图 1 , 图 1为 本申请实施例提供的蜂窝通信结构的示意图。如图 1所示，蜂窝通信结构如同 一个蜂窝网， 每个网格由多个小区构成， 其中， 每个网格作为一个基站。 请参 阅图 2 , 图 2为本申请第一实施例提供的一种无线通信方法的流程图。 其中， 图 2所示的无线通信方法从一网络设备方向进行的单侧描述。如图 2所示，本 实施例提供的无线通信方法包括：
S210、 获取用户设备与物理小区间的网络状态；
S220、选取用户设备与物理小区间的网络状态符合预设指标的物理小区的 通信资源构成虚拟小区；
S230、发送专用信令给用户设备，专用信令用于指示用户设备与虚拟小区 通过用户设备与物理小区间的网络状态符合预设指标的物理小区的通信资源 建立通信链路。
其中， 专用信令包括虚拟小区的标识。
本实施例提供的无线通信方法，基于云无线接入网架构， 以用户设备为中 心， 突破传统的无线通信方法以包括月良务小区的网络设备为中心的思想， 由网 络设备为用户设备分配通信资源。在云无线接入网架构，属于协作区域内的各 个发射点通过高速的回程线路连接，每个发射点的信号在云无线接入网中的核 心处理单元中被集中分配，使得整个无线通信系统可灵活的在大范围内实现协 作。
基于云无线入网的结构，本实施例提供的无线通信方法主要通过获取用户 设备与物理小区间的网络状态 ,选取用户设备与物理小区间的网络状态符合预 设指标的物理小区的通信资源构成虚拟小区，将发送专用信令给用户设备，指 示用户设备与虚拟小区通过虚拟小区包括的物理小区的通信资源建立通信链 路， 实现了与用户设备的通信要求相匹配的可用通信资源的重组， 不再局限于 传统的物理小区按照规定划界， 呈现出蜂窝状的小区划界通信模式，使得服务 用户设备的物理小区可以来自不同的发射点或者不同的处理点，只要满足用户 设备与物理小区间的网络状态符合预设指标的条件即可， 不再受地域性限制， 服务小区的通信资源自由动态变化， 实现多重维度的组合。 而且， 虚拟资源包 括的物理小区的若干种通信资源可以在协作区域内被集中调度，实现不同的用 户设备需求通信时， 符合要求的通信资源被重复利用。
请参阅图 3,图 3为本申请实施例提供的无线通信方法的应用场景示意图。 如图 3所示， 示出用户设备 UE1在蜂窝通信结构所在通信区域中的位置， 蜂 窝通信架构其中， 用户设备 UE1处于三个网格（基站） 的交界处， 三个基站 的标记分别^ ^站 1、 基站 2、 基站 3, 其中， 网络设备根据获取到的用户设 备 UE1与用户设备 UE1所在的通信位置附近的若干物理小区间的网络状态， 为了快速确定可用的通信资源， 可以设定一定范围的协作区域， 判断在此协作 区域范围内的物理小区与用户设备 UE1 的网络状态是否符合预设条件。 在本 实施例中， 设定基站 1、 基站 2、 基站 3为包含于一协作区域内， 则网络设备 获取到用户设备 UE1分别与基站 1、基站 2和基站 3中的若干物理小区之间的 网络状态。 其中， 检测到基站 1、 基站 2与基站 3中的若干物理小区与用户设 备 UEl的信道状态符合预设条件， 则基站 1、 基站 2、 基站 3中的若干小区都 可作为发射点。 进一步， 若网络设备测量到基站 1与若干用户设备都有通信， 其所承担的负载较多， 所以为达到负载均衡的目的， 则排除基站 1中的物理小 区作为用户设备 UE1的服务小区，选择基站 2、或者基站 3中的物理小区作为 用户设备 UE1 的服务小区。 进一步， 每个基站的配置属性都不相同， 则导致 每个基站的计算处理能力也不一样，若网络设备检测到基站 2的计算处理能力 较低， 则排除基站 2中的物理小区作为用户设备 UE1的服务小区。
若网络设备检测到基站 1、 基站 2、 基站 3中的物理小区与用户设备 UE1 之间的网络状态遭到严重的信号干扰，指示网络状态不符合预设条件， 则可进 一步扩大协作区域的范围， 即扩大到达协作区域包括基站 1、 基站 2、 基站 3 和基站 4, 若基站 4与用户设备 UE1之间的网络状态没有受到任何信号干扰， 且基站 4的负载状态空闲， 网络设备检测到基站 4与用户设备 UE1之间的网 络状态符合各项预设条件， 则可使基站 4中的服务小区作为用户设备 UE1的 服务小区。 即本实施例提供的无线通信方法， 不再局限于传统的物理小区按照 规定划界， 呈现出蜂窝状的小区划界通信模式，使得服务用户设备的物理小区 可以来自不同的发射点或者不同的处理点，只要满足用户设备与物理小区间的 网络状态符合预设指标的条件即可， 不再受地域性限制，使得服务小区的通信 资源被自由配置， 动态组合。
请参阅图 4, 图 4为本申请实施例提供的另一种无线通信方法的应用场景 示意图。 如图 4所示， 示出了用户设备 UE2从基站 1、基站 2和基站 3的交界 处移向基站 4、基站 5的交界处时的场景。 网络设备获取到用户设备 UE2的状 态在 tl时刻时， 用户设备 UE2处于基站 1、 基站 2和基站 3的交界处， 网络 设备获取到基站 1、基站 2、 基站 3中的若干物理小区与用户设备 UE2之间的 网络状态都符合预设条件， 基站 1、 基站 2、 基站 3中的若干物理小区都可以 作为用户设备 UE2的服务小区或者候选服务小区。 网络设备获取到用户设备 UE2的状态在 t2时刻时， 用户设备 UE2处于基站 4、 基站 5的交界处， 网络 设备获取到基站 4、基站 5中的若干物理小区与用户设备 UE2之间的网络状态 都符合预设条件， 则基站 4、 基站 5 中的若干物理小区都可以作为用户设备 UE2的服务小区或者其中部分可作为用户设备 UE2的候选服务小区。 当然， 网络设备可以运用 GPS技术或者基站定位技术检测到用户设备 UE2的行动轨 迹， 来为其分配基站， 以检测其与相关基站中的物理小区之间的网络状态来确 定可通信的通信资源。 所以会在不同的时刻为自由移动的用户设备 UE2分配 多维度组合的网络通信资源。其中， 多维度组合的网络通信资源是指初步定位 基站 1和基站 2、 基站 3都可以作为可通信的基站， 然而， 网络设备可能会进 一步检测到基站 1的负载较低， 下行发射功率较大， 所以选取基站 1中的物理 小区作为用户设备发射控制信道的服务小区，而检测到基站 2的负载处于空闲 状态， 与用户设备 UE2之间的信道干扰度较小， 则选取基站 2作为用户设备 发射下行数据信道的服务小区， 而检测到基站 3与用户设备 UE2之间的数据 接收信道的干扰度较小，则可选取基站 3作为用户设备接收上行数据信道的服 务小区。 基站 1、 基站 2、 基站 3中的物理小区的服务通信资源各不相同， 为 用户设备 UE2完成通信提供了多种维度组合的通信资源， 实现了上下行链路 数据发射、接收或者控制信道的解耦， 不再局限于特定的小区担负服务用户设 备的所有功能， 达到一切以用户设备为中心，免去服务小区的通信资源的地域 性限制， 实现多种维度的通信资源的组合， 提高了通信效率和通信质量。
同理， 不同的协作集内的物理小区与用户设备之间的网络状态不同，若检 测到一协作集内的物理小区与用户设备之间的网络状态不符合预设条件，而另 一协作集内的物理小区与用户设备之间的网络状态符合预设条件，则可选取网 络状态不符合预设条件的协作集作为静默协作集，在协作时不发送数据或者接 收数据， 但是其的计算能力可以为网络状态符合预设条件的协作集服务。
