一种毫米波相控阵波束对准方法及通信设备 本申请要求于 2013年 1月 22日提交中国专利局、 申请号为 CN 201310023438.7、 发明名称为"一种毫米波相控阵波束对准方法及通信设备"的中国专利申请的优先权, 其全部内容通过弓 I用结合在本申请中。 技术领域 本发明涉及通信技术领域, 特别是涉及一种毫米波相控阵波束对准方法及通信 设备。 背景技术 目前大规模应用的近距无线通信标准主要工作在 2.4GHz、 5GHz频段, 而 60GHz 毫米波通信技术正日益活跃起来。 和现有频段相比, 60GHz毫米波通信技术能够实 现电子设备间每秒数个吉比特 (Gbps ) 级的超高速数字无线传输。 未来无线通信设 备将可工作在 2.4GHz/5GHz/60GHz三个频段, 2.4GHz/5GHz频段用来实现较低速数 据传输, 60GHz频段用来实现高速数据传输。
60GHz毫米波位于无线电频谱在大气传输衰减峰值之一, 在空间传播衰耗大。 受限制于毫米波器件技术和成本等因素, 小型毫米波发射功率受限, 因此单辐射单 元天线的 60GHz毫米波通信距离较短。要增加毫米波通信距离, 实现高速数据传输, 可以采用相控阵定向波束天线来收发毫米波信号。 在 60GHz系统中, 天线尺寸的縮 小使得单个设备可以方便的配置多个天线, 而相控阵天线的配置可以方便的进行波 束成形。 收发天线经过波束扫描搜索, 当发射设备的相控阵波束与接收设备的相控阵波 束相互对准时, 发射设备与接收设备之间才能实现相通信。 现有技术中, 该毫米波相控阵波束对准的方法包括: 由发射设备发射信号进行 波束扫描搜索, 接收设备收到发射设备发射的信号后, 原接收设备变为发射设备, 原发射设备变为接收设备, 再经过波束扫描搜索, 原发射设备在接收到原接收设备 发射的信号后, 两设备才能互相知道对方在哪个方向, 完成整个波束搜索过程, 实 现两设备之间的相控阵波束对准。 其中, 在进行波束搜索时采用的是穷举法, 由于 搜索时没有明确搜索目标和停止算法, 发射设备只能通过穷尽搜索, 遍历所有可能 的波束指向方向后, 才能发现接收设备所在的通信波束指向角度。 因此, 现有技术 中该相控阵波束对准方法时间冗长, 效率低下。 发明内容 本发明实施例中提供了一种毫米波相控阵波束对准方法及通信设备, 能够提高 相控阵波束对准的效率。 为了解决上述技术问题, 本发明实施例公开了如下技术方案: 第一方面, 提供一种毫米波相控阵波束对准方法, 包括: 第一设备与第二设备通过低频段通信链路进行通信, 确定搜索角度;

另一种方式是可以在上一步骤 101中, 第 一设备与第二设备确定多个搜索角度, 然后在步骤 102中, 第一设备按照一定 的角度顺序逐一发射毫米波信号, 直至接收到第二设备的反馈信息, 搜索到第 二设备。 步骤 103, 第一设备接收第二设备发送的反馈信息, 其中, 第二设备在所 述搜索角度指示的方向上接收到第一毫米波信号后发送反馈信息。 第二设备在确定的搜索角度指示的方向上接收到第一设备发送的第一毫 米波信号后向第一设备发送反馈信息。 在本发明的一实施例中, 第一设备接收第二设备发送的反馈信息, 具体可 以是: 第一设备按照搜索角度接收第二设备在该搜索角度发射的第二毫米波信 号, 其中, 第二设备在该搜索角度接收到第一毫米波信号后发射第二毫米波信 号。 该方式即第二设备接收到第一毫米波信号后, 第一设备与第二设备互换角 色, 由第二设备向第一设备发射第二毫米波信号, 重复搜索过程, 以确定第一 设备的位置, 该过程与现有技术中盲搜索过程中的搜索方式类似。 在一具体实例中, 如图 2b所示, 为便于计算, 假设波束覆盖范围由 >^个 子区域组成, 总数量为1 个子区域。 收发双方按照 1、 2、 3、 4 顺序同步扫描 搜索水平子区域, 根据水平 (或垂直) 方向可把扫描区域划分为 M (例图中 M=4 ) 个角度按照上述方法进行收发协同。 以水平角度为例, 1 到 4层每层有
M个扫描区域, 每层进行一次扫描搜索最多可能需要 M^次, M层最多需要1 ^次 搜索, 比单向盲搜索减少了 M倍。 优选的, 在本发明的另一实施例中, 第一设备接收第二设备发送的反馈信 息, 具体可以是: 第一设备接收第二设备通过低频段通信链路, 如 2.4GHz/5GHz频段, 发送 的反馈信息, 该反馈信息用于表明第二设备在确定的搜索角度接收到第一毫米 波信号。 该方式中, 第二设备收到第一设备发送的第一毫米波信号后, 立即通过
2.4GHz或 5GHz低频段向第一设备发送应答信号,告知第一设备终止搜索过程, 以避免后续无效波束搜索过程。 当确定的搜索角度为多个时, 该反馈信息也即 应答信号中可以包括第二设备收到的第一设备发出的第一毫米波信号的波束 方向编号, 如 Z 1 的编号, 这样第一设备就知道了第二设备位于发射天线哪个 波束方向上。 若如上一方式中第二设备不进行应答反馈将这一信息返回给第一设备, 则 第二设备和第一设备要调换收发角色, 再进行一次波束扫描才能交换波束指向 信息, 完成波束扫描搜索过程。 因此, 本方式中第二设备的应答方法最多可节 省一半扫描搜索次数, 更加提高了相控阵波束对准的效率。 步骤 104, 第一设备在接收到反馈信息后, 确定与第二设备在该搜索角度 指示的方向上实现毫米波相控阵波束对准。 在本步骤中, 若第一设备在该搜索角度指示的方向上接收到第二设备发射 的第二毫米波信号, 则第一设备即可确定在该搜索角度指示的方向上可以与第 二设备实现毫米波相控阵波束对准, 也即在接收到第二毫米波信号的接收方向 上与第二设备对准。 若第一设备接收到的是第二设备通过低频段通信链路发送的反馈信息, 也 即应答信号, 该应答信号中包含用于表明所述第二设备在所述搜索角度接收到 所述第一毫米波信号的信息, 则第一设备也可以知道在该搜索角度指示的方向 上可以与第二设备实现毫米波相控阵波束对准。 若第一设备接收到的反馈信息 中包括第二设备接收到的第一毫米波信号的波束方向信息, 则第一设备在接收 到反馈信息后, 确定与第二设备在反馈信息中的第一毫米波信号的波束方向上 实现毫米波相控阵波束对准。 本发明实施例通过利用设备中 2.4GHz或 5GHz等低频段作为辅助通信链 路, 确定搜索角度, 使得第一设备与第二设备按照该搜索角度进行协同收发同 波束搜索过程, 实现了毫米波相控阵波束对准。 该方法减少了波束搜索的盲目 性, 大大减小了波束扫描次数, 提高了相控阵波束对准的效率, 縮短了 60GHz 等毫米波频段通信链路建立时间, 节省了设备功耗, 提升了用户体验。 在本发明的另一实施例中, 在第一设备与第二设备通过低频段通信链路进行 通信, 确定搜索角度之前, 第一设备还可以预先对第二设备的位置进行粗定位, 确 定搜索范围, 其中, 该搜索范围是指搜索角度所属的角度范围。该确定搜索范围的 过程可以有多种方式, 例如: 方式一, 当第一设备与第二设备之间的距离小于等于距离阈值时, 第一设 备发射宽波束毫米波信号对第二设备进行搜索; 本发明实施例中的宽波束毫米 波的频率可以是但不仅限于 60GHz。 第一设备接收第二设备发送的信号归属信息, 所述信号归属信息中包含所 述第二设备接收到的宽波束毫米波信号所属的第一设备的天线扇区; 第一设备将该天线扇区指示的角度范围确定为搜索范围。 第一设备将自己天线覆盖范围分为若干覆盖区域 (扇区), 那么它向这些 区域(扇区)分别发送宽波束毫米波信号, 这个信号里包含了这些区域(扇区) 的编号, 例如 1,2,3...这样第二设备接收到这个信号后, 自然就知道它接收到的 是第一设备在哪个扇区发送的信号, 然后把这个扇区编号通过低频段通信链路 反馈给第一设备, 那么第一设备就知道第二设备在哪个扇区覆盖范围内。 其中, 第一设备与第二设备之间的距离小于等于距离阈值即第一设备与第 二设备之间的距离在宽波束有效通信距离范围内, 两设备之间通过采用较宽波 束扫描搜索, 可以互相找到对方的粗略位置, 从而确定搜索范围。 该过程与现 有技术类似, 此次不再赘述。 方式二, 如图 3所示, 该确定搜索范围的方法可以包括: 步骤 301, 第一设备通过低频段通信链路接收第二设备的高度信息。 第一设备和第二设备内部均可通过设置高度传感器和 /或垂直角度传感器 等感知设备高度和 /或与地面的垂直角度, 还可以是内置高度信息寄存器, 设备 类型寄存器等。 高度信息存储寄存器, 用于存储设备一般工作时相对室内地面所处高度。 此高度可以是一个固定值, 可以是一个高度范围。 可以是出厂默认值, 也可由 用户改变设定。 设备类型寄存器用于用编号表示设备类型, 比如笔记本, 电视机, 手机, 投影仪等等。 第二设备可以通过读取高度信息存储寄存器中的信息等方式获得第二设 备的高度信息, 然后将该高度信息通过 2.4GHz或 5GHz等低频段发送至第一 设备。 步骤 302, 第一设备根据自身的高度信息及第二设备的高度信息, 确定搜 索范围。 第一设备通过读取高度信息存储寄存器中的信息等方式获得自身的高度 信息, 然后根据自身的高度信息及接收到的第二设备的高度信息, 即可确定两 设备之间的连线相对于水平方向或垂直方向的大致角度, 从而可以确定搜索范 围。 另外, 第一设备和第二设备可以相互交换设备类型, 天线类型等信息, 从 而可以确定主从搜索设备, 例如以上实施例中, 以第一设备为主搜索设备, 第 二设备为从搜索设备, 当然在两设备之间也可以是对等的, 不必区分主从搜索 设备。 在通过上述方式确定搜索范围后, 第一设备与第二设备通过低频段通信链路 进行通信, 在该搜索范围内确定搜索角度。 本发明实施例通过粗定位确定搜索范围, 进一步縮小了波束扫描搜索范 围, 减少了波束扫描搜索次数, 从而可以更加快速的建立通信链路, 减少设备 功耗, 提升用户体验。 在一具体实例中, 如图 2c所示, 第一设备的全搜索角度为 , 通过粗定位 得知第二设备位于 θι角度范围内。 这样第一设备进行窄波束扫描时只需在 &1这 一小范围内进行, 从而縮小了搜索范围, 减少了扫描次数。 本发明实施例中, 以上确定搜索角度第一、 二设备进行收发协同的方式, 第二设备通过低频段通信链路进行应答的方式, 粗定位确定搜索范围的方式以 及现有技术中的盲搜索方式可以根据需要进行任意组合, 例如, 收发协同、 收 发协同与应答的组合、 粗定位与收发协同的组合、 粗定位与收发协同及应答的 组合等, 此处不再详细说明, 具体请参见上述实施例的描述。 其中, 在一优选实施例中, 如图 2d 所示, 若双方通信设备具备相应硬件 条件, 采用粗定位与收发协同及应答的组合, 则可达到本发明最佳优选实施实 例, 最大可能扫描搜索次数为 次。 参见图 4, 为本发明实施例另一种毫米波相控阵波束对准的方法流程图。 本发明实施例与前述实施例的区别在于: 前述实施例是针对收发协同、 收 发协同与粗定位和 /或应答的组合进行的描述,本发明实施例中主要针对应答与 其他方式的组合进行说明。 该方法可以包括: 步骤 401, 第一设备发射毫米波信号对第二设备进行搜索。 该第一设备为相控阵天线设备, 第二设备为需要与第一设备对准的另一相 控阵天线设备。 在本步骤中, 第一设备可以采用盲搜索的方式向多个方向发射 毫米波信号搜索第二设备, 该毫米波信号的频率可以为 60GHz。 步骤 402, 第一设备接收第二设备通过低频段通信链路发送的反馈信息, 该反馈信息用于表明第二设备接收到第一设备发射的毫米波信号。 第二设备在接收到第一设备在某个方向发射的毫米波信号后,通过 2.4GHz 或 5GHz等低频段向第一设备发送反馈信息进行应答, 该反馈信息用于表明第 二设备接收到第一设备发射的毫米波信号。 具体的, 第二设备收到第一设备发送的第一毫米波信号后, 立即通过 2.4GHz或 5GHz低频段向第一设备发送应答信号,告知第一设备终止搜索过程, 以避免后续无效波束搜索过程。 该应答信号可以包括第二设备收到的第一设备 发出的波束方向编号, 如图 2a所示的 Z 1的编号, 这样第一设备就知道了第二 设备位于发射天线哪个波束方向上。 步骤 403, 第一设备在接收到反馈信息后, 确定与第二设备在毫米波信号 的发射方向实现毫米波相控阵波束对准。 第一设备在接收到上述反馈信息也即应答信号后, 即可获知在哪个角度可 以与第二设备实现毫米波相控阵波束对准。 当第一设备在多个发射方向发射毫米波信号对所述第二设备进行搜索时, 该反馈信息中包括第二设备接收到的毫米波信号的波束方向信息。 第一设备在 接收到反馈信息后, 确定与第二设备在反馈信息中的毫米波信号的波束方向上 实现毫米波相控阵波束对准。 本发明实施例通过第二设备对第一设备进行应答反馈将接收到毫米波信 号的相关信息返回给第一设备, 省去了第二设备和第一设备调换收发角色, 再 进行一次波束扫描才能交换波束指向信息, 完成波束扫描搜索的过程。 因此, 本方式中第二设备的应答方法最多可节省一半扫描搜索次数, 更加提高了相控 阵波束对准的效率, 縮短了 60GHz等毫米波频段通信链路建立时间, 节省了设 备功耗, 提升了用户体验。 在本发明的另一实施例中, 在第一设备发射毫米波信号对第二设备进行盲 搜索之前, 第一设备还可以预先对第二设备的位置进行粗定位, 确定搜索范围。该 确定搜索范围的过程可以有多种方式, 例如: 方式一, 当第一设备与第二设备之间的距离小于等于距离阈值时, 第一设 备发射宽波束毫米波信号对第二设备进行搜索; 第一设备接收第二设备发送的信号归属信息, 所述信号归属信息中包含所 述第二设备接收到的宽波束毫米波信号所属的第一设备的天线扇区; 第一设备将天线扇区指示的角度范围确定为搜索范围。 方式二, 该确定搜索范围的方法可以包括: 所述第一设备通过低频段通信链路接收所述第二设备的高度信息; 所述第一设备根据自身的高度信息及所述第二设备的高度信息, 确定搜索范 围。 以上两种方式的具体过程与前述实施例中的方式一、 方式二相同, 此处不再赘 述。 在通过上述方式确定搜索范围后,第一设备在确定的搜索范围内发射毫米波信 号对第二设备进行搜索。 本发明实施例通过粗定位确定搜索范围, 进一步縮小了波束扫描搜索范围, 减 少了波束扫描搜索次数, 从而可以更加快速的建立通信链路, 减少设备功耗, 提升 用户体验。 参见图 5a, 为本发明实施例另一种毫米波相控阵波束对准的方法流程图。 本发明实施例与前述实施例的区别在于: 前述实施例是针对收发协同、 收 发协同与粗定位和 /或应答的组合, 以及针对应答与其他方式的组合进行描述, 本发明实施例中主要针对粗定位与盲搜索的组合方法进行描述。 该方法可以包括: 步骤 501, 第一设备确定搜索第二设备的搜索范围。 该确定搜索范围的过程可以有多种方式, 例如: 方式一, 当第一设备与第二设备之间的距离小于等于距离阈值时, 第一设 备发射宽波束毫米波信号对第二设备进行搜索; 第一设备接收第二设备发送的信号归属信息, 所述信号归属信息中包含所 述第二设备接收到的宽波束毫米波信号所属的第一设备的天线扇区; 第一设备将所述天线扇区指示的角度范围确定为搜索范围。 方式二, 该确定搜索范围的方法可以包括: 所述第一设备通过低频段通信链路接收所述第二设备的高度信息; 所述第一设备根据自身的高度信息及所述第二设备的高度信息, 确定搜索范 围。 以上两种方式的具体过程与前述实施例中的方式一、 方式二相同, 此处不再赘 述。 步骤 502, 第一设备在该搜索范围内发射第一毫米波信号对第二设备进行 搜索。 步骤 503, 第一设备接收第二设备发射的第二毫米波信号, 其中, 第二设 备在接收到第一毫米波信号后发射第二毫米波信号。 步骤 504, 第一设备在接收到第二毫米波信号后, 确定与第二设备在接收所 述第二毫米波信号的方向上实现毫米波相控阵波束对准。 以上步骤 502〜504为第一设备为信号发射方, 第二设备为信号接收方, 对 第二设备进行搜索, 第二设备接收到信号后, 第一设备与第二设备互换角色, 第二设备发射信号对第一设备进行搜索的过程, 该过程与现有技术中的搜索过 程相同, 此处不再赘述。 其与现有技术的区别仅在于, 在本实施例中, 首先通 过粗定位确定搜索范围后, 第一设备在该搜索范围内发射信号进行搜索。 本发明实施例通过粗定位确定搜索范围, 縮小了波束扫描搜索范围, 减少了波 束扫描搜索次数, 从而可以更加快速的建立通信链路, 减少设备功耗, 提升用户体 验。 在一具体实例中, 如图 5b 所示, 为便于计算, 假设波束覆盖范围由 >^个 子区域组成, 总数量为旨2个子区域。 如果采用盲搜索, 接收方接收到信号最大可 能搜索次数为 。 发射方向每个子区域发射一遍波束搜索序列, 需要 次, 而接 收方要对每个方向接收: 1 次, 最差情况下, 需要总搜索次数为 次, 而采用上粗 定位确定搜索范围后, 单向最大可能搜索次数可降低为 、e 次。 以上各实施例中均以第一设备作为执行主体进行说明, 下面以第二实施例 作为执行主体进行说明。 参见图 6, 为本发明实施例另一种毫米波相控阵波束对准的方法流程图。 该方法可以包括: 步骤 601,第二设备与第一设备通过低频段通信链路进行通信,确定搜索角度。 步骤 602, 第二设备在所述搜索角度指示的方向上接收所述第一设备发射的第 一毫米波信号。 步骤 603, 第二设备在接收到所述第一毫米波信号后, 向所述第一设备发送反 馈信息, 以使所述第一设备在接收到所述反馈信息后, 确定与所述第二设备在所述 搜索角度指示的方向上实现毫米波相控阵波束对准。 本发明实施例通过利用设备中 2.4GHz或 5GHz等低频段作为辅助通信链 路, 确定搜索角度, 使得第一设备与第二设备按照该搜索角度进行协同收发同 波束搜索过程, 实现了毫米波相控阵波束对准。 该方法减少了波束搜索的盲目 性, 大大减小了波束扫描次数, 提高了相控阵波束对准的效率, 縮短了 60GHz 等毫米波频段通信链路建立时间, 节省了设备功耗, 提升了用户体验。 在本发明另一实施例中, 第二设备在接收到所述第一毫米波信号后, 向所述第 一设备发送反馈信息, 包括: 第二设备在接收到所述第一毫米波信号后,在所述搜索角度指示的方向上发 射第二毫米波信号, 以使所述第一设备在所述搜索角度指示的方向上接收到所述 第二毫米波信号后,确定与所述第二设备在所述搜索角度指示的方向上实现毫米波 相控阵波束对准。 在本发明另一实施例中, 第二设备在接收到所述第一毫米波信号后, 向所述第 一设备发送反馈信息, 包括: 所述第二设备在接收到所述第一毫米波信号后,通过低频段通信链路向所述第 一设备发送反馈信息,所述反馈信息用于表明所述第二设备在所述搜索角度指示的 方向上接收到所述第一毫米波信号。 当确定的所述搜索角度为多个时, 所述反馈信息中包括所述第二设备接收 到的所述第一毫米波信号的波束方向信息, 以使所述第一设备在接收到所述反 馈信息后,确定与所述第二设备在所述反馈信息中的所述第一毫米波信号的波束 方向上实现毫米波相控阵波束对准。 在本发明另一实施例中,在所述第二设备与第一设备通过低频段通信链路进行 通信, 确定搜索角度之前, 还包括: 当所述第二设备与所述第一设备之间的距离小于等于距离阈值时,所述第二设 备接收所述第一设备发射的宽波束毫米波信号;
