Description
一种链路自适应的方法和设备 本申请要求于 2 01 3 年 1 0 月 22 日提交中国专利局、 申请号为 2 01 31 049 969 1. X , 发明名称为 "一种链路自适应的方法和设备" 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
本发明涉及通信领域, 尤其涉及一种链路自适应的方法和设 备。
背景技术
微波通信技术通常用于点到多点通信 (如卫星广播), 和点到 点通信 (如无线回传), 在无线回传通信中, 无线回传通信系统包 括回传远端和回传近端, 回传近端为靠近网络侧的回传设备, 回传 远端为远离网络侧的回传设备,该无线回传通信系统通过回传近端 与回传远端进行数据的传输, 从而为用户提供语音、 数据等业务通 信。
在实际应用中, 由于外部环境 (如大风) 的影响, 很容易导致 回传远端对应的天线和回传近端对应的天线的角度发生偏离,使得 回传远端和回传近端之间的通信链路失效,影响正常的通信。因此, 需要调整双方对应的天线的角度, 使双方的天线相互对准, 以保证 信号传输的质量。另外由于通信链路可能受到外界同频率其它设备 的无线信号干扰,也会造成回传远端和回传近端之间的通信链路失 效, 影响正常的通信。 因此, 同样需要调整双方对应的通信频率, 使双方选择另外一个相同的频率, 以保证信号传输的质量。 在现有技术中,主要通过人工的方式进行手工天线对准和手工 频率调整, 需要耗费天线对准与频率调整这段时间的人力成本, 而 且维护起来同样需要人工参与, 人力成本开销大, 增加了对准的难 度。

情形三: 第一天线设备在确定该 RSSI 小于第二 RSSI 门限, 并 且该 SINR小于 SINR预设门限时,选择与该第二天线设备进行频率 调整和天线对准。
同样地,第二天线设备也可以根据检测的 RSSI和 SINR确定进 行频率调整和 /或天线对准, 具体可以参考上述情形一至情形三, 此处不再赘述。
进一步地,该第一天线设备向该第二天线设备发送预设调整时 间。 或者, 接收该第二天线设备发送的预设调整时间。
其中,该预设调整时间用于指示该第一天线设备和该第二天线 设备开始进行频率调整和 /或天线对准的时间。
具体地,上述预设调整时间可以预先设置在上述第一天线设备 中, 也可以预先设置在第二天线设备中, 并通过协商消息发送至另 一端天线设备。
例如, 第一天线设备在 7 点钟时通过检测 RSSI 确定该链路未 失步, 但是根据 RSSI 以及对应的 SINR确定在 Ί点 30分 ( 即预设 调整时间 ) 进行频率调整和 /或天线对准后, 则将该时刻 (即 7 点 30分) 发送至第二天线设备, 以便第二天线设备在达到 7点 30分 同时开始与该第一天线设备进行频率调整和 /或天线对准。 上述只 是举例说明, 不作限定。
另外, 该协商消息还可以包括调整方式, 该调整方式包括频率 调整和 /或天线对准, 第一天线设备将确定的调整方式发送至第二 天线设备,则该第一天线设备和第二天线设备在达到该预设调整时 间后, 按照该调整方式进行频率调整和 /或天线对准。
具体地, 若该第一天线设备确定进行频率调整, 则将该预设调 整时间和调整方式( 即频率调整)发送至第二天线设备, 则该第一 天线设备和第二天线设备在达到该预设调整时间后, 进行频率调 整。
若该第一天线设备确定进行天线对准,则将该预设调整时间和 调整方式( 即天线对准)发送至第二天线设备, 则该第一天线设备 和第二天线设备在达到该预设调整时间后, 进行天线对准。
若该第一天线设备确定进行频率调整和天线对准,则将该预设 调整时间和调整方式( 即频率调整和天线对准)发送至第二天线设 备, 则该第一天线设备和第二天线设备在达到该预设调整时间后, 进行频率调整和天线对准。
当然, 由于第二天线设备也可以确定该链路未失步且该第二天 线设备确定进行频率调整和 /或天线对准, 因此, 该第一天线设备 也可以接收该第二天线设备发送的调整方式,以便该第一天线设备 和该第二天线设备在达到该预设调整时间后,根据该调整方式进行 频率调整和 /或天线对准, 以确定该第一天线设备对应天线和该第 二天线设备对应天线的发射频率。
另外, 在实际应用中, 第一天线设备和第二天线设备各自确定 的调整方式可能不同, 例如, 第一天线设备确定进行频率调整, 第 二天线设备确定进行天线对准, 此时, 第一天线设备和第二天线设 备既进行频率调整又进行天线对准, 又如, 第一天线设备确定进行 频率调整, 而第二天线设备确定进行频率调整和天线对准, 此时, 第一天线设备和第二天线设备既进行频率调整又进行天线对准,再 如, 第一天线设备确定进行频率调整, 而第二天线设备确定不进行 频率调整和 /或天线对准, 此时, 第一天线设备和第二天线设备仍 需要进行频率调整, 也就是说, 第一天线设备和第二天线设备中的 任一设备确定进行频率调整和 /或天线对准, 则该第一天线设备和 第二天线设备则相应的进行频率调整和 /或天线对准。 但是为了方 便描述, 在以下各实施例中, 都以第一天线设备和第二天线设备各 自确定的调整方式相同为例进行描述(即第一天线设备确定进行频 率调整, 第二天线设备也确定进行频率调整; 或者, 第一天线设备 确定进行天线对准, 第二天线设备也确定进行天线对准; 或者, 第
一天线设备确定进行频率调整和天线对准,第二天线设备也确定进 行频率调整和天线对准), 不作限定。
进一步地, 第一天线设备在确定所述 RSSI 小于所述第一 RSSI 门限时, 选择与所述第二天线设备进行频率调整和天线对准。
需要说明的是, 第一天线设备在确定该 RSSI 小于该第一 RSSI 门限时, 即确定与第二天线设备之间的链路失步, 该第一天线设备 停止向第二天线设备发送信号,该信号可以是指示链路同步的同步 信号。 同样地, 第二天线设备通过检测与第一天线设备之间的链路 的 RSSI 确定该链路失步, 因此, 该第一天线设备与该第二天线设 备进行频率调整和天线对准,以使得该第一天线设备和该第二天线 设备之间的链路恢复同步。
进一步地, 上述进行频率调整可以为: 第一天线设备从预设天 线角度调整集合中确定天线角度, 并维持该天线角度, 并与该第二 频率调整设备进行频率调整。
具体地,第一天线设备将该预设频率调整集合中的第一频率在 第一预定时间内作为该第一天线设备对应的天线频率,并检测该链 路的第一 RSSI, 并在确定该第一 RSSI 大于或等于第一 RSSI 门限 时,检测该链路的第一 SINR, 在根据该第一 RSSI和该第一 SINR确 定该第一频率不是该第一天线设备对应天线的工作频率后,若达到 该第一预定时间,将该预设频率调整集合中的第二频率在第一预定 时间内作为该第一天线设备对应的天线频率。
其中,第一天线设备在确定该第一 RSSI 小于该第一 RSSI 门限 时, 确定该第一频率不是该第一天线设备对应天线的工作频率; 或 者,第一天线设备在确定该第一 RSSI大于或等于该第一 RSSI门限, 并且该第一 SINR小于该 SINR预设门限时,确定该第一频率不是该 第一天线设备对应天线的工作频率。
同样地,第二天线设备将预设频率调整集合中的第一频率在第 三预定时间内作为该第一天线设备对应的天线频率,并检测该链路 的 RSSI, 在确定该 RSSI 大于或等于第一 RSSI 门限时,检测该链路 的 SINR, 在根据该 RSSI 和该 SINR确定该第一频率不是该第二天 线设备对应天线的工作频率后, 若达到该第三预定时间, 将该预设 频率调整集合中的第二频率在第三预定时间内作为该第一天线设
备对应天线的工作频率。
其中, 在本发明一种可能的实现方式中, 该第一预定时间大于 或者等于该第三预定时间与该预设频率调整集合中的频率的数量 的乘积, 或者, 该第三预定时间大于或者等于该第一预定时间与该 预设频率调整集合中的频率的数量的乘积, 在本发明实施例中, 以 该第三预定时间为该第一预定时间与该预设频率调整集合中的频 率的数量的乘积为例进行说明, 本发明对此不作限定。
示例地,根据图 3对上述第一天线设备和第二天线设备进行频 率调整进行具体的说明,该预设频率调整集合包括 F0至 F4五个可 调频率,该第一天线设备在第一预定时间 T1 内将频率 F0作为对应 的天线频率,该第二天线设备在第三预定时间 T2 内将频率 F0作为 对应的天线频率, 该第三预定时间为该第一预定时间乘以五(即该 预设频率调整集合包括的频率的数量), 这样, 在该第一天线设备 对应的天线频率为 F0且第二天线设备对应的天线频率为 F0时,若 该第一天线设备和第二天线设备分别根据检测到的第一 RSSI 和第 二 RSSI确定该频率 F0不是该第一天线设备和第二天线设备对应天 线的工作频率, 则在第一天线设备达到第一预定时间 T1 时, 将该 第一天线设备对应的天线频率由频率 F0调整为频率 F1, 此时, 由 于第二天线设备还未达到第三预定时间 T2, 因此, 该第二天线设 备仍然将 F0作为对应的天线频率, 这样, 在该第一天线设备对应 的天线频率为 F1且第二天线设备对应的天线频率为 F0时,该第一 天线设备和第二天线设备根据各自检测的 RSSI 和 SINR 确定频率 F1和频率 F0是否分别为该第一天线设备和该第二天线设备对应天 线的工作频率,若仍未确定该第一天线设备和该第二天线设备对应 天线的工作频率, 则在达到第一预定时间 T1 时, 继续将第一天线 设备对应的天线频率依次调整为预设频率调整集合中剩余的频率 ( 即频率 F2 至频率 F4 ), 直至确定该第一天线设备和该第二天线 设备对应天线的工作频率。
在该第一天线设备将该预设频率调整集合中每一个频率( 即频 率 F0至频率 F4 ) 都依次检测过后, 若还没有确定第一天线设备和 第二天线设备对应天线的工作频率,则在第二天线设备达到第三预 定时间 T2时,第二天线设备将对应的天线频率由频率 F0调整为频
率 Fl, 此时, 第一天线设备继续将对应的天线频率依次调整为预 设频率调整集合中的频率( 即 F0至 F4 )并对应检测 RSSI和 SINR, 当第二天线设备再次达到第三预定时间时,若仍未确定该第一天线 设备和该第二天线设备对应天线的工作频率,则继续将第二天线设 备对应的天线频率依次调整为预设频率调整集合中剩余的频率(即 频率 F2 至频率 F4 ), 直至确定该第一天线设备和该第二天线设备 对应天线的工作频率。 上述描述只是举例说明, 不作限定。
由上可以看出,本发明实施例中的频率调整主要通过任一端的 天线设备从预设频率调整集合中固定一频率作为对应的天线频率, 另一端天线设备则将该预设频率调整集合中的每一个频率依次作 为对应的天线频率,并通过检测 RSSI和 SINR确定第一天线设备和 第二天线设备对应天线的工作频率,若仍未确定第一天线设备和第 二天线设备对应天线的工作频率,则任一端的天线设备将当前的天 线频率调整为预设频率调整集合中的其它频率,直至确定第一天线 设备和第二天线设备对应天线的工作频率。
进一步地, 第一天线设备在根据该第一 RSSI 和该第一 SINR 确定该第一频率是该第一天线设备对应天线的工作频率后,向该第 二天线设备发送同步信号,以便该第二天线设备根据该同步信号确 定该第二天线设备当前的天线频率为该第二天线设备对应天线的 工作频率。
具体地, 第一天线设备在确定该第一 RSSI 大于或等于该第一 RSSI 门限, 并且该第一 SINR 大于或等于该 SINR预设门限时, 确 定该第一频率为该第一天线设备对应天线的工作频率。
同样地, 第二天线设备向该第一天线设备发送同步信号, 以便 该第一天线设备根据该同步信号确定该第一天线设备的当前频率 为该第一天线设备对应天线的工作频率。
需要说明的是, 在本发明另一种可能的实现方式中, 上述第一 预定时间和第三预定时间也可以相同, 示例地, 该预设频率调整集 合包括 F0至 F4五个可调频率,第一天线设备和第二天线设备在根 据预设调整时间确定进行频率调整时, 都分别将频率 F0作为对应 的天线频率, 并根据检测的 RSSI 和 SINR确定频率 F0是否为对应 天线的工作频率, 若确定频率 FQ 不是对应天线的工作频率, 则在
该第一天线设备和第二天线设备达到第一预定时间和第三定时间 (第一预定时间和第三预定时间相同 )时, 该第一天线设备和第二 天线设备同时 (第一预定时间和第三预定时间相同 ) 将频率 F0依 次调整为 F1, 并根据检测的 RSSI和 SINR确定该频率 F0是否是对 应天线的工作频率, 若确定频率 F1 不是对应天线的工作频率, 继 续同时将频率 F1依次调整为 F2至 F4,直至根据检测的 RSSI和 SINR 确定对应天线的工作频率, 这样, 保证第一天线设备的天线频率始 终和第二天线设备相同的天线频率 (如第一天线设备的频率 F0和 第二天线设备的频率 F0 ) 进行检测, 从而提升频率调整的效率。
另外,上述第一天线设备按照第一预定时间依次将预设频率调 整集合中的频率作为对应的天线频率可以按照一定的顺序依次将 预设频率调整集合中的频率作为对应的天线频率, 例如, 第一天线 设备可以按照发射频率由低至高的顺序依次将预设频率调整集合 中的频率作为对应的天线频率, 当然, 也可以按照由高至低的顺序 依次将预设频率调整集合中的频率作为对应的天线频率,本发明对 此不作限定。
进一步地, 上述进行天线对准具体可以为: 第一天线设备从预 设频率调整集合中确定天线频率, 维持该天线频率, 并与该第二频 率调整设备进行天线对准。
具体地,第一天线设备将预设天线角度调整集合中的第一天线 角度在第二预定时间内作为该第一天线设备对应的天线角度,并检 测该链路的第二 RSSI,并在确定该第二 RSSI 大于或等于第一 RSSI 门限时,检测该链路的第二 S INR ,在根据该第二 RSS I和该第二 S INR 确定该第一天线角度不是该第一天线设备对应天线的工作角度后, 若达到该第二预定时间,将该预设天线角度调整集合中的第二天线 角度在第二预定时间内作为该第一天线设备对应的天线角度。
其中,第一天线设备在确定该第二 RSSI小于该第一 RSSI门限, 确定该第一天线角度不是该第一天线设备对应天线的工作角度;或 者,第一天线设备在确定该第二 RSSI 大于或等于该第一 RSSI 门限 且小于该第二 RSSI 门限时, 确定该第一天线角度不是该第一天线 设备对应天线的工作角度。
同样地,第二天线设备将预设天线角度调整集合中的第一天线
角度在第四预定时间内作为该第一天线设备对应的天线角度,并检 测该链路的 RSSI, 在确定该 RSSI 大于或等于第一 RSSI 门限时,检 测该链路的 SINR, 在根据该 RSSI 和该 SINR确定该第一天线角度 不是该第二天线设备对应天线的工作角度后,若达到该第四预定时 间,将该预设天线角度调整集合中的第二频率在第四预定时间内作 为该第一天线设备对应天线的工作角度。
其中, 在本发明一种可能的实现方式中, 该第二预定时间大于 或者等于该第四预定时间与该预设频率调整集合中的频率的数量 的乘积, 或者, 该第四预定时间大于或者等于该第二预定时间与该 预设频率调整集合中的频率的数量的乘积, 在本发明实施例中, 以 该第四预定时间为该第二预定时间与该预设频率调整集合中的频 率的数量的乘积为例进行说明, 本发明对此不作限定。
示例地,根据图 4对上述第一天线设备和第二天线设备进行天 线对准进行具体的说明, 该预设天线角度调整集合包括 AO 至 A4 五个可调天线角度, 该第一天线设备在第二预定时间 T3 内将角度 AO作为对应的天线角度, 该第二天线设备在第四预定时间 T4 内将 角度 AO作为对应的天线角度, 该第四预定时间为该第二预定时间 乘以五 (即该预设天线角度调整集合包括的角度的数量), 这样, 在该第一天线设备对应的天线角度为 AO且第二天线设备对应的天 线角度为 AO 时, 若该第一天线设备和第二天线设备分别根据检测 到的第一 RSSI 和第二 RSSI确定该角度 AO不是该第一天线设备和 第二天线设备对应天线的工作角度,则在第一天线设备达到第二预 定时间 T3时,将该第一天线设备对应的天线角度由角度 AO调整为 角度 A1, 此时, 由于第二天线设备还未达到第四预定时间 T4, 因 此, 该第二天线设备仍然将 AO作为对应的天线角度, 这样, 在该 第一天线设备对应的天线角度为 A1 且第二天线设备对应的天线角 度为 AO时, 该第一天线设备和第二天线设备根据各自检测的 RSSI 和 SINR确定角度 A1 和角度 AO是否分别为该第一天线设备和该第 二天线设备对应天线的工作角度,若仍未确定该第一天线设备和该 第二天线设备对应天线的工作角度,则在达到第二预定时间 T3时, 继续将第一天线设备对应的天线角度依次调整为预设天线角度调 整集合中剩余的天线角度 ( 即角度 A2 至角度 A4 ), 直至确定该第
一天线设备和该第二天线设备对应天线的工作角度。
在该第一天线设备将该预设天线角度调整集合中每一个天线 角度 ( 即角度 AO至角度 A4 ) 都依次检测过后, 若还没有确定第一 天线设备和第二天线设备对应天线的工作角度,则在第二天线设备 达到第四预定时间 T4 时, 第二天线设备将对应的天线角度由角度 AO调整为角度 A1, 此时, 第一天线设备继续将对应的天线角度依 次调整为预设天线角度调整集合中的天线角度 (即 AO至 A4 ) 并对 应检测 RSSI和 SINR, 当第二天线设备再次达到第四预定时间时, 若仍未确定该第一天线设备和该第二天线设备对应天线的工作角 度,则继续将第二天线设备对应的天线角度依次调整为预设天线角 度调整集合中剩余的天线角度 ( 即角度 A2 至角度 A4 ), 直至确定 该第一天线设备和该第二天线设备对应天线的工作角度。上述描述 只是举例说明, 不作限定。
由上可以看出,本发明实施例中的天线对准主要通过任一端的 天线设备从预设天线角度调整集合中固定一天线角度作为对应的 天线角度,另一端天线设备则将该预设天线角度调整集合中的每一 个角度依次作为对应的天线角度,并通过检测 RSSI和 SINR确定第 一天线设备和第二天线设备对应天线的工作角度,若仍未确定第一 天线设备和第二天线设备对应天线的工作角度,则任一端的天线设 备将当前的天线角度调整为预设天线角度调整集合中的其它角度, 直至确定第一天线设备和第二天线设备对应天线的工作角度。
进一步地, 第一天线设备在根据该第二 RSSI 和该第二 SINR 确定该第一天线角度是该第一天线设备对应天线的工作角度后,向 该第二天线设备发送同步信号,以便该第二天线设备根据该同步信 号确定该第二天线设备当前的天线角度为该第二天线设备对应天 线的工作角度。
具体地, 第一天线设备在确定该第二 RSSI 大于或等于该第二 RSSI 门限时, 确定该第一天线角度是该第一天线设备对应天线的 工作角度。
同样地, 第二天线设备向该第一天线设备发送同步信号, 以便 该第一天线设备根据该同步信号确定该第一天线设备的当前天线 角度为该第一天线设备对应天线的工作角度。
需要说明的是, 在本发明另一种可能的实现方式中, 上述第二 预定时间和第四预定时间也可以相同, 示例地, 该预设天线角度调 整集合包括 AO至 A4五个可调角度,第一天线设备和第二天线设备 在根据预设调整时间确定进行天线对准时, 都分别将角度 AQ作为 对应的天线角度, 并根据检测的 RSSI 和 SINR确定角度 AO是否为 对应天线的工作角度, 若确定角度 AO 不是对应天线的工作角度, 则在该第一天线设备和第二天线设备达到第二预定时间和第四预 定时间 (第二预定时间和第四预定时间相同 ) 时, 该第一天线设备 和第二天线设备同时(第二预定时间和第四预定时间相同 )将角度 AO依次调整为 A1,并根据检测的 RSSI和 SINR确定该角度 AO是否 是对应天线的工作角度,若确定角度 A1 不是对应天线的工作角度, 继续同时将角度 A1依次调整为 A2至 A4, 直至根据检测的 RSSI和 SINR 确定对应天线的工作角度, 这样, 保证第一天线设备的天线 角度始终和第二天线设备相同的天线角度(如第一天线设备的角度 AO和第二天线设备的角度 AQ ) 进行检测, 从而提升天线对准的效 率。
另外,上述第一天线设备按照第一预定时间依次将预设天线角 度调整集合中的天线角度作为对应的天线的角度可以是按照一定 的顺序依次将预设天线角度调整集合中的天线角度作为对应的天 线的角度, 例如, 第一天线设备可以按照角度由小至大的顺序依次 将预设天线角度调整集合中的天线角度作为对应的天线角度, 当 然,也可以按照由大至小的顺序依次将预设天线角度调整集合中的 天线角度作为对应的天线角度, 本发明对此不作限定。
在本发明另一种可能的实现方式中, 当第一天线设备和第二天 线设备之间的链路失步, 且传输的信号受到强烈的干扰, 导致信号 的传输质量较差时, 可以将上述频率调整和天线对准结合起来, 从 而进一步提高信号的传输质量, 其具体的实现包括以下两种方式: 方式一: 第一频率调整设备固定天线角度, 并基于该天线角度 与第二天线设备进行频率调整, 在频率调整完成后, 将该天线角度 调整为预设天线角度调整集合中另一天线角度,并再次与第二天线 设备进行频率调整,若仍未确定该第一天线设备和该第二天线设备 对应的天线频率,则继续将第一天线设备对应的天线角度依次调整
为预设天线角度调整集合中剩余的角度并进行频率调整,直至确定 第一天线设备和第二天线设备对应的天线频率。
其中,这里的频率调整可以参考上述第一频率设备进行频率调 整的描述, 此处不再赘述。
方式二: 第一频率调整设备固定对应的天线频率, 并基于该天 线频率与第二天线设备进行天线对准, 在天线对准完成后, 将该天 线频率调整为预设频率调整集合中另一频率,并再次与第二天线设 备进行天线对准,若仍未确定该第一天线设备和该第二天线设备对 应天线的工作频率,则继续将第一天线设备对应的天线频率依次调 整为预设频率调整集合中剩余的频率并进行天线对准,直至确定第 一天线设备和第二天线设备对应天线的工作频率。
其中,这里的天线对准可以参考上述第一频率设备进行天线对 准的描述, 此处不再赘述。
由上可知, 方式一与方式二的区别在于, 方式一是先固定天线 角度再进行频率调整, 在频率调整后, 仍然无法确定工作频率时, 再继续调整天线角度; 方式二是先固定天线的频率再进行天线对 准, 在天线对准后, 仍无法确定工作频率时, 再继续进行频率调整。
需要说明的是, 由于在正常通信中, 信号的传输更容易受到强 烈的干扰, 因此, 在实际应用中, 优选地可以采用方式一中的方案, 从而更快的提高信号的传输质量。
采用上述方案, 通过采用上述方案, 第一天线设备能够根据链 路的 R S S I 和对应的 S I NR确定进行频率调整和 /或天线对准, 从而 根据当前链路的状态智能的实现链路的 自适应, 不需要人工的干 预, 在保证信号传输质量的情况下, 减少了人力成本。 本发明实施例提供一种链路自适应的方法, 如图 5所示, 该方 法实施例中, 第一天线设备可以是回传远端或者回传近端, 则对应 的第二天线设备则为回传近端或者回传远端, 该方法包括:
S 5 01、 第一天线设备检测与第二天线设备之间的链路的 R S S I。 需要说明的是,本发明实施例以第一天线设备和第二天线设备 各自确定的调整方式( 包括频率调整和天线对准)相同为例进行描 述(即第一天线设备确定进行频率调整, 第二天线设备也确定进行
频率调整; 或者, 第一天线设备确定进行天线对准, 第二天线设备 也确定进行天线对准; 或者, 第一天线设备确定进行频率调整和天 线对准, 第二天线设备也确定进行频率调整和天线对准), 不作限 定。
S502、第一天线设备确定 RSSI是否大于或等于第一 RSSI门限。 在第一天线设备确定该 RSSI 是否大于或等于第一 RSSI 门限 时, 执行步骤 S503。
在第一天线设备确定该 RSSI 小于该第一 RSSI 门限时,执行步 骤 S509.
S503、 第一天线设备检测该链路的 SINR。
需要说明的是, 确定该 RSSI 大于或等于该第一 RSSI 门限, 即 表示该链路并未失去同步 (简称 "失步"), 第一天线设备和第二天 线设备会相互传输同步信号, 但是, 由于在信号的传输过程中, 该 链路可能会受到干扰, 同样会影响信号传输的质量, 因此, 该第一 天线设备可以在确定该 RSSI 大于或等于该第一 RSSI 门限时,进一 步根据该链路内传输的接收信号获取 SINR, 该接收信号可以是上 述的同步信号,该第一天线设备根据该 RSSI和该 SINR与该第二天 线设备进行频率调整和 /或天线对准。
S504、第一天线设备在确定该 RSSI大于或等于第二 RSSI门限, 并且该 SINR小于 SINR预设门限时, 确定进行频率调整, 执行步骤 S507。
其中, 该第二 RSSI 门限大于该第一 RSSI 门限。
S505、 第一天线设备在确定该 RSSI 小于第二 RSSI 门限, 并且 该 SINR大于或等于 SINR预设门限时, 确定进行天线对准, 执行步 骤 S508。
S506、 第一天线设备在确定该 RSSI 小于第二 RSSI 门限, 并且 该 SINR小于 SINR预设门限时, 确定进行频率调整和天线对准, 执 行步骤 S509。
具体可以参考上述实施例中对图 2的描述, 此处不再赘述, 另 外, 需要说明的是, 第二天线设备也可以根据检测的 RSSI和 SINR 确定进行频率调整和 /或天线对准, 具体可以参考上述步骤 S504 至 S506, 此处不再赘述。
进一步地,该第一天线设备向该第二天线设备发送预设调整时 间。 或者, 接收该第二天线设备发送的预设调整时间。
其中,该预设调整时间用于指示该第一天线设备和该第二天线 设备开始进行频率调整和 /或天线对准的时间。
具体地,上述预设调整时间可以预先设置在上述第一天线设备 中, 也可以预先设置在第二天线设备中, 并通过协商消息发送至另 一端天线设备。
例如, 第一天线设备在 7 点钟时通过检测 RSSI 确定该链路未 失步, 但是根据 RSSI 以及对应的 SINR确定在 Ί点 30分 ( 即预设 调整时间 ) 进行频率调整和 /或天线对准后, 则将该时刻 (即 7 点 30分) 发送至第二天线设备, 以便第二天线设备在达到 7点 30分 同时开始与该第一天线设备进行频率调整和 /或天线对准。 上述只 是举例说明, 不作限定。
另外, 该协商消息还可以包括调整方式, 该调整方式包括频率 调整和 /或天线对准, 第一天线设备将确定的调整方式发送至第二 天线设备,则该第一天线设备和第二天线设备在达到该预设调整时 间后, 按照该调整方式进行频率调整和 /或天线对准。
S507、 第一天线设备与第二天线设备进行频率调整。
具体地,第一天线设备将该预设频率调整集合中的第一频率在 第一预定时间内作为该第一天线设备对应的天线频率,并检测该链 路的第一 RSSI, 并在确定该第一 RSSI 大于或等于第一 RSSI 门限 时,检测该链路的第一 SINR, 在根据该第一 RSSI和该第一 SINR确 定该第一频率不是该第一天线设备对应天线的工作频率后,若达到 该第一预定时间,将该预设频率调整集合中的第二频率在第一预定 时间内作为该第一天线设备对应的天线频率。
其中,第一天线设备在确定该第一 RSSI 小于该第一 RSSI 门限 时, 确定该第一频率不是该第一天线设备对应天线的工作频率; 或 者,第一天线设备在确定该第一 RSSI大于或等于该第一 RSSI门限, 并且该第一 SINR小于该 SINR预设门限时,确定该第一频率不是该 第一天线设备对应天线的工作频率。
同样地,第二天线设备将预设频率调整集合中的第一频率在第 三预定时间内作为该第一天线设备对应的天线频率,并检测该链路
的 RSSI, 在确定该 RSSI 大于或等于第一 RSSI 门限时,检测该链路 的 SINR, 在根据该 RSSI 和该 SINR确定该第一频率不是该第二天 线设备对应天线的工作频率后, 若达到该第三预定时间, 将该预设 频率调整集合中的第二频率在第三预定时间内作为该第一天线设 备对应天线的工作频率。
其中, 在本发明一种可能的实现方式中, 该第一预定时间大于 或者等于该第三预定时间与该预设频率调整集合中的频率的数量 的乘积, 或者, 该第三预定时间大于或者等于该第一预定时间与该 预设频率调整集合中的频率的数量的乘积, 在本发明实施例中, 以 该第三预定时间为该第一预定时间与该预设频率调整集合中的频 率的数量的乘积为例进行说明, 本发明对此不作限定。
具体可以参考上述实施例对图 3的描述, 此处不再赘述了。 需要说明的是, 在本发明另一种可能的实现方式中, 上述第一 预定时间和第三预定时间也可以相同, 示例地, 该预设频率调整集 合包括 F0至 F4五个可调频率,第一天线设备和第二天线设备在根 据预设调整时间确定进行频率调整时, 都分别将频率 F0作为对应 的天线频率, 并根据检测的 RSSI 和 SINR确定频率 F0是否为对应 天线的工作频率, 若确定频率 FQ 不是对应天线的工作频率, 则在 该第一天线设备和第二天线设备达到第一预定时间和第三定时间 (第一预定时间和第三预定时间相同 )时, 该第一天线设备和第二 天线设备同时 (第一预定时间和第三预定时间相同 ) 将频率 F0依 次调整为 F1, 并根据检测的 RSSI和 SINR确定该频率 F0是否是对 应天线的工作频率, 若确定频率 F1 不是对应天线的工作频率, 继 续同时将频率 F1依次调整为 F2至 F4,直至根据检测的 RSSI和 SINR 确定对应天线的工作频率, 这样, 保证第一天线设备的天线频率始 终和第二天线设备相同的天线频率 (如第一天线设备的频率 F0和 第二天线设备的频率 F0 ) 进行检测, 从而提升频率调整的效率。
进一步地, 第一天线设备在根据该第一 RSSI 和该第一 SINR 确定该第一频率是该第一天线设备对应天线的工作频率后,向该第 二天线设备发送同步信号,以便该第二天线设备根据该同步信号确 定该第二天线设备当前的天线频率为该第二天线设备对应天线的 工作频率。
具体地, 第一天线设备在确定该第一 RSSI 大于或等于该第一 RSSI 门限, 并且该第一 SINR 大于或等于该 SINR预设门限时, 确 定该第一频率为该第一天线设备对应天线的工作频率。
同样地, 第二天线设备向该第一天线设备发送同步信号, 以便 该第一天线设备根据该同步信号确定该第一天线设备的当前频率 为该第一天线设备对应天线的工作频率。
另外,上述第一天线设备按照第一预定时间依次将预设频率调 整集合中的频率作为对应的天线频率可以按照一定的顺序依次将 预设频率调整集合中的频率作为对应的天线频率, 例如, 第一天线 设备可以按照发射频率由低至高的顺序依次将预设频率调整集合 中的频率作为对应的天线频率, 当然, 也可以按照由高至低的顺序 依次将预设频率调整集合中的频率作为对应的天线频率,本发明对 此不作限定。
S508、 第一天线设备与第二天线设备进行天线对准。
具体地,第一天线设备将预设天线角度调整集合中的第一天线 角度在第二预定时间内作为该第一天线设备对应的天线角度,并检 测该链路的第二 RSSI,并在确定该第二 RSSI 大于或等于第一 RSSI 门限时,检测该链路的第二 S INR ,在根据该第二 RSS I和该第二 S INR 确定该第一天线角度不是该第一天线设备对应天线的工作角度后, 若达到该第二预定时间,将该预设天线角度调整集合中的第二天线 角度在第二预定时间内作为该第一天线设备对应的天线角度。
其中,第一天线设备在确定该第二 RSSI小于该第一 RSSI门限, 确定该第一天线角度不是该第一天线设备对应天线的工作角度;或 者,第一天线设备在确定该第二 RSSI 大于或等于该第一 RSSI 门限 且小于该第二 RSSI 门限时, 确定该第一天线角度不是该第一天线 设备对应天线的工作角度。
同样地,第二天线设备将预设天线角度调整集合中的第一天线 角度在第四预定时间内作为该第一天线设备对应的天线角度,并检 测该链路的 RSSI, 在确定该 RSSI 大于或等于第一 RSSI 门限时,检 测该链路的 SINR, 在根据该 RSSI 和该 SINR确定该第一天线角度 不是该第二天线设备对应天线的工作角度后,若达到该第四预定时 间,将该预设天线角度调整集合中的第二频率在第四预定时间内作
为该第一天线设备对应天线的工作角度。
其中, 在本发明一种可能的实现方式中, 该第二预定时间大于 或者等于该第四预定时间与该预设频率调整集合中的频率的数量 的乘积, 或者, 该第四预定时间大于或者等于该第二预定时间与该 预设频率调整集合中的频率的数量的乘积, 在本发明实施例中, 以 该第四预定时间为该第二预定时间与该预设频率调整集合中的频 率的数量的乘积为例进行说明, 本发明对此不作限定。
具体可以参考上述实施例对图 4 的描述, 此处不再赘述了。 在本发明另一种可能的实现方式中,上述第二预定时间和第四 预定时间也可以相同, 示例地, 该预设天线角度调整集合包括 AO 至 A4五个可调角度, 第一天线设备和第二天线设备在根据预设调 整时间确定进行天线对准时, 都分别将角度 AO作为对应的天线角 度, 并根据检测的 RSSI 和 SINR确定角度 AO是否为对应天线的工 作角度, 若确定角度 AO 不是对应天线的工作角度, 则在该第一天 线设备和第二天线设备达到第二预定时间和第四预定时间(第二预 定时间和第四预定时间相同 )时, 该第一天线设备和第二天线设备 同时 (第二预定时间和第四预定时间相同 ) 将角度 AO依次调整为 A1, 并根据检测的 RSSI 和 SINR确定该角度 AO是否是对应天线的 工作角度, 若确定角度 A1 不是对应天线的工作角度, 继续同时将 角度 A1依次调整为 A2 至 A4, 直至根据检测的 RSSI 和 SINR确定 对应天线的工作角度, 这样, 保证第一天线设备的天线角度始终和 第二天线设备相同的天线角度 (如第一天线设备的角度 AO 和第二 天线设备的角度 AQ ) 进行检测, 从而提升天线对准的效率。
另外,上述第一天线设备按照第一预定时间依次将预设天线角 度调整集合中的天线角度作为对应的天线的角度可以是按照一定 的顺序依次将预设天线角度调整集合中的天线角度作为对应的天 线的角度, 例如, 第一天线设备可以按照角度由小至大的顺序依次 将预设天线角度调整集合中的天线角度作为对应的天线角度, 当 然,也可以按照由大至小的顺序依次将预设天线角度调整集合中的 天线角度作为对应的天线角度, 本发明对此不作限定。
进一步地, 第一天线设备在根据该第二 RSSI 和该第二 SINR 确定该第一天线角度是该第一天线设备对应天线的工作角度后,向
该第二天线设备发送同步信号,以便该第二天线设备根据该同步信 号确定该第二天线设备当前的天线角度为该第二天线设备对应天 线的工作角度。
具体地, 第一天线设备在确定该第二 R S S I 大于或等于该第二 R S S I 门限时, 确定该第一天线角度是该第一天线设备对应天线的 工作角度。
同样地, 第二天线设备向该第一天线设备发送同步信号, 以便 该第一天线设备根据该同步信号确定该第一天线设备的当前天线 角度为该第一天线设备对应天线的工作角度。
S 5 09、 第一天线设备与第二天线设备进行频率调整和天线对 准。
具体, 该步骤 S 5 09 包括以下两种实现方式:
方式一: 第一频率调整设备固定天线角度, 并基于该天线角度 与第二天线设备进行频率调整, 在频率调整完成后, 将该天线角度 调整为预设天线角度调整集合中另一天线角度,并再次与第二天线 设备进行频率调整,若仍未确定该第一天线设备和该第二天线设备 对应的天线频率,则继续将第一天线设备对应的天线角度依次调整 为预设天线角度调整集合中剩余的角度并进行频率调整,直至确定 第一天线设备和第二天线设备对应的天线频率。
方式二: 第一频率调整设备固定对应的天线频率, 并基于该天 线频率与第二天线设备进行天线对准, 在天线对准完成后, 将该天 线频率调整为预设频率调整集合中另一频率,并再次与第二天线设 备进行天线对准,若仍未确定该第一天线设备和该第二天线设备对 应天线的工作频率,则继续将第一天线设备对应的天线频率依次调 整为预设频率调整集合中剩余的频率并进行天线对准,直至确定第 一天线设备和第二天线设备对应天线的工作频率。
由上可知, 方式一与方式二的区别在于, 方式一是先固定天线 角度再进行频率调整, 在频率调整后, 仍然无法确定工作频率时, 再继续调整天线角度; 方式二是先固定天线的频率再进行天线对 准, 在天线对准后, 仍无法确定工作频率时, 再继续进行频率调整。
需要说明的是, 由于在正常通信中, 信号的传输更容易受到强 烈的干扰, 因此, 在实际应用中, 优选地可以采用方式一中的方案,
从而更快的提高信号的传输质量。
采用上述方案,第一天线设备和第二天线设备能够根据链路的
RSSI 和对应的 SINR 确定进行频率调整和 /或天线对准, 从而根据 当前链路的状态智能的实现链路的自适应, 不需要人工的干预, 在 保证信号传输质量的情况下, 减少了人力成本。

具体可以参考上述实施例对图 3的描述, 此处不再赘述了。 需要说明的是, 在本发明另一种可能的实现方式中, 上述第一 预定时间和第三预定时间也可以相同, 示例地, 该预设频率调整集 合包括 F0至 F4五个可调频率,第一天线设备和第二天线设备在根 据预设调整时间确定进行频率调整时, 都分别将频率 F0作为对应
的天线频率, 并根据检测的 RSSI 和 SINR确定频率 F0是否为对应 天线的工作频率, 若确定频率 FQ 不是对应天线的工作频率, 则在 该第一天线设备和第二天线设备达到第一预定时间和第三定时间 (第一预定时间和第三预定时间相同 )时, 该第一天线设备和第二 天线设备同时 (第一预定时间和第三预定时间相同 ) 将频率 F0依 次调整为 F1, 并根据检测的 RSSI和 SINR确定该频率 F0是否是对 应天线的工作频率, 若确定频率 F1 不是对应天线的工作频率, 继 续同时将频率 F1依次调整为 F2至 F4,直至根据检测的 RSSI和 SINR 确定对应天线的工作频率, 这样, 保证第一天线设备的天线频率始 终和第二天线设备相同的天线频率 (如第一天线设备的频率 F0和 第二天线设备的频率 F0 ) 进行检测, 从而提升频率调整的效率。
