技术领域
本发明涉及移动通信技术领域, 尤其涉及微微蜂窝小区的配置方法、 装 置和系统。 背景技术 移动通信网络可以采用蜂窝结构, 即在不同地点架设多个基站, 每个基 站形成一个小区, 每个基站负责其小区区域内的移动用户的通信。 为了保证 移动用户能够获得不间断的、 连续的进行通信, 相邻小区设有一定的重叠区 域, 从而使得移动用户在通信过程中, 能够从一个小区切换到另外一个小区。
在这种传统的单层小区系统中, 为了提高整个系统的容量, 可以提高每 个小区的容量。 但是, 在一个较大区域内, 并不是所有地方都需要很高的容 量, 多数情况下只有局部热点地区才需要^ ί艮高的容量。 如果为业务量比较小 的区域提供了很高的容量, 会因为没有足够的用户使用, 而造成系统资源的 浪费。 也就是说, 通过提高整个小区的容量来提高整个系统的容量, 效率较 低。
为此,可以采用多层小区结构,在 3GPP的 LTE标准中称为 Heterogeneous
Network, 简称 HetNet。 具体的, 如图 1所示, 用宏小区 (Macro-cel l )实现 该区域的无缝连续覆盖, 在热点地区采用微微蜂窝 (Pico ) 重叠覆盖。 由于 微微蜂窝能够针对热点地区较大的业务量需求, 提供 4艮高的容量, 从而实现 系统容量的 "按需分配" 。
但是, 采用上述方案, 在实际应用中, 热点小区的位置有时是不固定的, 例如, 在临时举行运动会的地方, 会因为运动会的召开而成为热点地区, 当 运动会结束后, 该地区又恢复为非热点地区。 在临时的热点地区通常不会预 设微微蜂窝, 而专门为了临时热点地区设置微微蜂窝需要时间和人力, 造成 不必要的资源浪费。 热点小区的微微蜂窝也有出现故障的情况, 若热点小区 的微微蜂窝出现了故障, 则该热点小区内的通信就会中断, 给移动用户带来 不便。 发明内容

本发明实施例提供了一种 蜂窝小区的配置方法, 如图 3 所示, 包括 以下步骤:
301、 第一宏基站向第一目标宏基站发送第一服务请求消息, 第一目标宏 基站具有波束成形虚拟多层网络结构的功能, 第一服务请求消息用于向第一 目标宏基站请求波束覆盖, 第一服务请求消息中包含发送该服务请求消息的 宏基站 ID信息以及需要波束覆盖的指定区域的位置信息。
在第一宏基站无法为其宏小区内的指定区域服务时, 例如, 由于新的商 场或者商业区的简历、 或者体育赛事、 或者集会等, 在第一宏基站的宏小区 1 中形成局部热点区域, 为了提供该热点区域高容量的波束覆盖, 提升该热点 区域单位面积上的吞吐量, 并且提高该热点区域以外的频谱利用率, 宏基站 可以向第一目标宏基站发送第一服务请求消息, 第一目标宏基站可以为具有 波束成形虚拟多层网络结构的功能, 具有波束成形虚拟多层网络结构如图 2 所示。 第一服务请求消息用于向该第一目标宏基站请求波束覆盖, 第一服务 请求消息中可以包含发送该服务请求消息的宏基站 ID信息以及需要波束覆盖 的指定区域的位置信息。
302、 第一目标宏基站向指定区域提供波束覆盖。
在第一目标宏基站为指定区域提供波束覆盖后, 该波束覆盖形成微微蜂 窝小区, 指定区域内的用户可以使用该波束覆盖进行通信。 本实施例提供的微微蜂窝小区的配置方法, 当宏基站无法服务其宏小区 内的指定区域时, 可以向具有波束成形虚拟 Hetnet的宏基站发送请求波束覆 盖的第一服务请求消息, 请求邻近的宏基站为该指定区域建立微微蜂窝小区, 在所述第一目标宏基站为所述指定区域提供波束覆盖后, 构成微微蜂窝小区, 所述指定区域内的用户使用该波束覆盖进行通信, 使其邻近的宏基站能够为 其提供服务。
作为本实施例的一种改进, 本发明实施例提供另一种微微蜂窝小区的配 置方法, 如图 4所示, 包括以下步骤:
401、 第一宏基站根据宏小区 1内指定区域的位置和业务量判断是否需要 向第一目标宏基站请求波束覆盖。 若第一宏基站判断出需要向第一目标宏基 站请求波束覆盖, 则执行步骤 402 , 否则流程结束。
具体的, 本步骤可以包括:
第一步, 第一宏基站根据指定区域, 本实施例中可以为热点区域, 业务 量和用户的位置判断是否需要用微小区对热点区域进行波束覆盖, 若不需要, 则流程结束; 若需要, 则执行第二步。
第二步, 第一宏基站根据自身的系统架构和站址部署判断是否能否为该 热点区域提供 Pico覆盖, 若第一宏基站无法为该热点区域提供波束覆盖, 则 第一宏基站需要周围的宏基站提供外来虚拟 Pi co覆盖服务。
402、 第一宏基站向第一目标宏基站发送第一服务请求消息。 第一目标宏 基站具有波束成形虚拟多层网络结构的功能, 第一服务请求消息用于向第一 目标宏基站请求波束覆盖, 第一服务请求消息中包含发送该服务请求消息的 宏基站 ID信息以及需要波束覆盖的指定区域的位置信息。
在第一宏基站无法为其宏小区内的指定区域服务时, 可以是第一宏基站 没有 HetNet架构、 热点区域没有布设微基站、 或者本小区内的基站已无法提 供 P ico覆盖时。 由于新的商场或者商业区的简历、 或者体育赛事、 或者集会 等, 在第一宏基站的宏小区 1 中形成局部热点区域, 为了提供该热点区域高 容量的波束覆盖, 提升该热点区域单位面积上的吞吐量, 并且提高热点区域 及所属宏小区的频谱利用率, 宏基站可以向第一目标宏基站发送第一服务请 求消息, 由第一目标宏基站形成波束覆盖本小区内指定区域 。
本实施例中, 第一目标宏基站可以为具有波束成形虚拟多层网络结构的 功能, 第一服务请求消息用于向该第一目标宏基站请求波束覆盖, 第一服务 请求消息中可以包含发送该服务请求消息的宏基站 ID信息以及需要波束覆盖 的指定区域的位置信息。
虚拟 Pico的调度可以是集中式的, 由高层节点统一管理 P ico的调度; 也可以是分布式的, 由第一宏基站在其相邻的宏基站之间进行资源协调。
第一宏基站在请求虚拟 Pi co服务时与周围宏基站的信令交互可以通过广 播的方式, 也可以通过与具有波束成型虚拟 Hetnet功能的宏基站之间的链路 进行, 具体实现可以是 X2接口或者 Over the a i r ( OTA )等。
403、 第一目标宏基站判断其是否有空闲的波束。 若第一目标宏基站判断 出有空闲的波束, 则执行步骤 404 , 否则, 流程结束。
当第一宏基站周围具有提供波束成型虚拟 HetNet功能的第一目标宏基站 收到第一服务请求消息后, 首先判断自身是否有空闲的波束阵列天线)用于 为第一宏基站提供虚拟 Pi co覆盖。 如果有, 则根据热点地区的位置计算第一 目标宏基站到热点地区的路径损耗, 并将计算得出的路径损耗以及第一目标 宏基站的 ID发送给第一宏基站。
本步骤中的路径损耗可以是通过参考信号计算的, 在已知其发射功率的 情况下, 就可以直接计算出对应的路径损耗, 具体的, 第一目标宏基站接收 来自需要提供波束覆盖内的用户终端发送的上行探测信号 ( Sounding Reference S i gna l , SRS )。 其发射功率由第一宏基站通过宏基站之间的接口 链路(X2等)告知第一目标宏基站。 第一目标宏基站就可以根据接收功率和 对应的 SRS发射功率直接计算出对应的路径损耗。
404、 第一宏基站接收第一目标宏基站发送的包含路径损耗和第一目标基 站 ID信息的响应消息。
405、 第一宏基站根据响应消息从第一目标宏基站中获取路径损耗最小的 第二目标宏基站。
第一宏基站收到周围第一目标宏基站发送的响应信息后, 从第一目标宏 基站中选出所有待选波束中路径损耗最小的那个用于形成虚拟 P i co覆盖。
最小路径损耗是上行方向上的最优基站接入准则。 外来微微蜂窝小区中 的用户离第一目标宏基站距离较远时, 需要较大的上行发射功率, 这就会对 其它的用户产生干扰。 而如果选用路径损耗最小的第一目标宏基站, 则可以 减小这种干扰。
406、 第一宏基站判断第二目标宏基站的路径损耗值是否小于预设门限 值。
为了降低外来微微蜂窝小区中用户的上行信号给其它用户造成的干扰, 需要设置一个路径损耗的门限值, 只有当能接入的虚拟 Pico所属阵列天线到 热点区域的最小路径损耗小于预设的门限值时, 才能由路径损耗最小的那个 邻近宏基站来提供虚拟 Pico覆盖。
当所述第二目标宏基站的路径损耗小于预设门限值时,执行步骤 407 , 否 则, 流程结束。
407、 第一宏基站根据第二目标宏基站的 ID信息向第二目标宏基站发送 第二服务请求消息。
第一宏基站向提供虚拟 Pi co覆盖服务的第一目标宏基站发送第二服务请 求消息。
作为本实施例的一种实施方式, 第一宏基站可以在第二服务请求消息中 携带所述指定区域使用的频段范围 , 使被第二目标宏基站的波束覆盖的指定 区域与本宏小区内该区域附近的用户之间使用正交频段。
具体的, 第一宏基站可以将热点区域可以使用的频段资源发送给第二目 标宏基站。 第一宏基站内的小区为宏小区 1 , 第二目标宏基站提供的波束覆盖 形成微微蜂窝小区, 该微微蜂窝小区和宏小区 1 内其附近的用户使用正交的 频段, 以避免干扰删除带来的复杂运算。 第一宏基站 根据热点地区周边的用 户负载来决定分配给!^敖蜂窝小区附近的 Macro用户和虚拟 P ico用户的频率 资源。 这里的频谱分配可以将频率资源分为几个部分, 比如频率资源的编号 为 1 ~ 10, 如果宏小区 1中热点地区周边的用户所需的频率为 1和 2 , 那么编 号为 3 ~ 10 的频率资源就可以提供给热点区域的用户。 宏小区内的其它用户 还是可以使用没有微小区覆盖之前的所有频段, 如图 5所示。
作为本实施例的一种实施方式, 可以由宏基站直接提供宏小区 (Macro ) 和微小区 (Pico )覆盖, 其中微小区是可移动的, 覆盖范围也是可以改变的。 微小区由宏基站采用阵列天线方式提供, 即宏基站可以利用阵列天线, 在下 行和 /或上行信号传输方向形成覆盖各个热点区域的波束, 这样宏基站就能实 现较优的 Macro-P ico联合资源调度与干扰管理。 从而实现容量的有效提升。 同时, 无需为每个微基站寻找站址、 也不用考虑供电、 回程(Backhaul )等 问题。 当热点区域位置、 大小等发生改变时, 只需要调节阵列天线的波束指 向、 波束宽度、 发射功率等, 就能完成系统组网的优化, 具有灵活的业务适 应性。
在 HetNet系统中, Pi co区域与所在的宏小区之间可以使用相同的频段, 此时宏基站的用户和微基站的用户之间干扰比较明显, 所以需要采取降低干 扰对系统性能影响的算法, 如干扰删除算法。 一般情况下, 为了避免复杂的 运算, 通常采用宏基站服务的用户和微基站服务用户采用正交频段( OFDM 系 统中使用不同的子载波) 的方式, 分配比例按照负载动态调整。 通常各 Pi co 之间距离较远, 由于无线信号传播的空间路径损耗, 其它 Pico的信号对某个 Pico的干扰与该微小区的有用信号相比小很多,因此 Pico之间的干扰可忽略, 不同 Pico可以实现完全的资源重用, 如在 0FDMA系统中, 不同 Pi co可以使 用相同的子载波资源。 从而大大提升了局部区域内的系统容量。
408、 根据第二目标宏基站的 ID信息向第二目标宏基站发送第二服务请 求消息, 第二服务请求消息用于指示所述第二目标宏基站向所述指定区域提 供波束覆盖。
409、 第二目标宏基站向指定区域提供波束覆盖。
410、 第二目标宏基站接收第一上行信号。 在第一目标宏基站中的第二目标宏基站为指定区域提供波束覆盖后, 指 定区域内的用户可以使用该波束覆盖进行通信。
本发明实施例中第二目标宏基站向指定区域提供了波束覆盖后, 该波束 覆盖区域形成微微蜂窝小区, 可以作为虚拟 Pico, 在虚拟 Pi co内用户的上行 信号可以直接发送, 并由第二目标宏基站对应的阵列天线直接接收。
411、 第一宏基站将直接接收并向第二目标宏基站转发的第二上行信号, 第二目标宏基站对第一上行信号和第二上行信号进行信号合并。
因为虚拟 Pico内频带可能和第二目标宏基站对应的宏小区 2中用户所使 用的频带重叠, 所以虚拟 P ico用户的上行信号可能对宏小区 2中的用户产生 干扰。 解决的方法可以是通过由第一宏基站中继上行信号的方式来适当降低 这些用户的上行发送功率。
如图 6 所示, 第一宏基站接收用户的上行信号, 然后将该上行信号放大 后转发给第二目标宏基站。 那么第一宏基站的作用可以相当于一个具有放大 转发作用的中继节点 (relay )。 虽然第二目标宏基站收到直接来自虚拟 Pico 用户的信号强度减弱了, 但是它能多收到来自第一宏基站转发的信号, 通过 对两路信号的合并, 还可以满足接收强度的要求。
本实施例中, 第一宏基站到第二目标宏基站的中继可以采用 AF (放大转 发)方式, 第一宏基站只需要滤出虚拟 Pico频段内的信号, 将该信号放大转 发给第二目标宏基站, 由于不需要进行解调和解码处理, 中继链路的时延很 小, 可以与多径相当。 两个基站之间的链路可以采用多种方式。 推荐的方式 为由第一宏基站指向第二目标宏基站的波束, 使系统开销比较小, 而且灵活 性较好, 时延较小。其它高速 X2接口也能作为两基站之间的链路, 比如微波、 光纤、 自由空间激光 ( Free Space Opt ica l, FSO )等。
本实施例中上行信号合并的方式可以有选择合并 (SC ) , 等增益合并 ( EGC ), 最大比合并(置 C )。
目前, HetNet 中, 解决热点区域覆盖问题, 可以在该区域布设微微基站 来提供接入服务。 假设一个传统的仅有 Macro基站覆盖的宏小区中出现临时 热点区域, 为了解决覆盖问题可以使用应急通信车, 但是这样的方案反应速 度较慢, 而且通信车的体积较大、 功耗较大, 且往往需要车载柴油发电机供 电, 使用起来很不方便。 还可以当宏小区中形成新的热点区域时, 希望通过 布设 Pico满足容量需求, 往往需要一定的时间。
本实施例提供的微微蜂窝小区的配置方法, 当宏基站无法服务其宏小区 内的指定区域时, 可以向具有波束成形虚拟 Hetnet的宏基站发送请求波束覆 盖的第一服务请求消息, 请求邻近的宏基站为该指定区域建立微微蜂窝小区, 在所述第一目标宏基站为所述指定区域提供波束覆盖后, 构成微微蜂窝小区, 所述指定区域内的用户使用该波束覆盖进行通信, 使其邻近的宏基站能够为 其提供服务。 由周围 HetNet架构的宏基站提供布设虚拟 Pico的临时服务, 将快速响应临时覆盖问题, 有效提升用户体验。
相邻宏基站之间虚拟 Pico资源可以协调, 在不增加系统成本的情况下, 通过具有波束成型虚拟 He t Ne t功能的宏基站向周围宏小区中的热点区域提供 Pico覆盖, 从而提高单位面积的吞吐量。 解决了传统宏小区中非长期热点地 区的覆盖问题, 避免增加微小区站址或者阵列天线的成本开销。 提高了系统 对场景的反应速度, 增大了相邻小区之间资源调度的灵活性。
