Description
本发明涉及移动通信技术领域，尤其涉及智能天线下行、上行通道校准的方法和***、存储介质。
智能天线阵列中各通道存在两种误差：非时变误差和时变误差。其中非时变误差可以通过离线校正进行精确测量，并在基带中进行补偿。时变误差主要由各通道的不一致性，如各通道的幅度、相位等因素随时变化，因此需要对各通道的幅度、相位误差采取在线校准和补偿。
目前在TDD***中对天线校正的方式主要为采取单天线发送，单天线接收，通过多次发送和接收实现对同一个小区基带板内控制信道或者数据信道进行干扰消除。
现有的这种天线校准方式对TDD业务会产生一定的影响，且效率低下，当待校准天线数量很大，需要花费很长的时间完成天线上、下行通道校准。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
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智能天线下行通道校准的方法。参照图1，图1为本发明的智能天线下行通道校准的方法一实施例的流程示意图。在该实施例中，该方法包括：
步骤S10、根据下行校准指令，为每个待校准的下行通道分配相应的下行时域校准序列；
本实施例中在接收到用户输入的下行校准指令，首先会计算待校准的下行通道的个数，然后根据待校准的下行通道的个数分配相应个数的下行时域校准序列。
步骤S20、在后续每个下行GAP间隙期间，同时获取多个待校准的下行通道对应的下行时域校准序列，将所获取的每个下行时域校准序列发送至对应的下行通道，直至分配的所有下行时域校准序列发送完毕；
本实施例中，同一所述下行GAP间隙发送的每个下行时域校准序列携带有区别本下行GAP间隙发送的其他下行时域校准序列的下行通道标识，以使根据该下行通道标识即可知晓该下行时域校准序列对应哪个下行通道。其中，本实施例可以为同一下行GAP间隙发送的下行时域校准序列分配不同相位，以相位作为区别同一下行GAP间隙发送的其他下行时域校准序列的下行通道标识，例如同一下行GAP间隙发送的相邻的下行时域校准序列依次相差2π/M的相位。
本实施例中为了缩短对所有待校准的下行通道的校准时间以及不影响待校准的下行通道正常运行TDD业务，在后续的下行GAP间隙期间向下行通道发送相应的下行时域校准序列，且在一个下行GAP间隙期间同时向多个待校准的下行通道发送相应的下行时域校准序列。当待校准的下行通
道数量过多，不适宜在同一个下行GAP间隙向所有待校准的下行通道发送相应的下行时域校准序列时，需要对待校准的下行通道进行分组，将所有待校准的下行通道对应的下行校准序列通过多个下行GAP间隙发送，每个下行GAP间隙发送一组下行通道对应的下行校准序列。即：当待校准的下行通道数量过大，则在步骤S10之后根据预设策略将待校准的下行通道分为多组，其中每组包括多个下行通道，每组包括的下行通道个数可以相同也可以不同。对对待校准的下行通道进行分组之后，在后续的每个下行GAP间隙期间从所述多组下行通道对应的下行时域校准序列中选择一组下行通道的对应的下行时域校准序列，然后发送至相应的下行通道中，直至所有的下行时域校准序列发送完毕，即所述后续每个下行GAP间隙期间所获取的多个下行时域校准序列为所述多组下行通道中的一组下行通道对应的下行时域校准序列。例如：待校准的下行通道为多个，在一个下行GAP间隙无法实现向所有待校准的下行通道同时发送相应的下行时域校准序列，则可以根据预设策略将所述多个下行通道分为X组，每组包括多个下行通道；然后，在接收下行校准指令之后X个下行GAP间隙发送相应的下行时域校准序列，如在接收下行校准指令之后的第1个下行GAP间隙向第1组待校准的下行通道发送相应的域校准序列、在第2个下行GAP间隙向第2组待校准的下行通道发送相应的下行时域校准序列，……在第X个下行GAP间隙向第X组待校准的下行通道发送相应的下行时域校准序列。
步骤S30、针对所述每个下行GAP间隙，实时收集经过每个下行通道的下行时域校准序列；对收集的所述下行时域校准序列进行耦合处理，生成下行综合时域校准序列；将所述下行综合时域校准序列发送至下行校准通道；将经过下行校准通道的下行综合时域校准序列转换为下行综合频域校准序列，并缓存所述下行综合频域校准序列；
本步骤S30中所述下行综合时域校准序列中包含有收集的每个时域校
准序列信息。所述下行综合频域校准序列包含有与所述收集的每个时域校准序列对应的频域校准序列信息。本步骤将所述下行综合时域校准序列发送至下行校准通道是为了使下行校准通道对所述下行综合时域校准序列进行相关处理，其中所述下行校准通道对下行综合时域校准序列进行处理采用的是现有方式，在此不再赘述。
步骤S40、根据缓存的所有下行综合频域校准序列计算待校准的下行通道的补偿值，根据所述补偿值对每个待校准的下行通道进行在线校准。
本实施例中，在所有的下行时域校准序列均发送到相应的下行通道，且所有的下行综合频域校准序列均已缓存后，根据缓存的所有下行综合频域校准序列计算待校准的下行通道的补偿值，即从每个下行综合频域校准序列提取相应的下行频域校准序列，然后根据每个下行频域校准序列计算对应的下行通道的补偿值。例如所有待校准的下行通道为J个，缓存有2个下行综合频域校准序列，其中第1个下行综合频域校准序列包含有第1至第I个下行通道对应的下行频域校准序列，第2个下行综合频域校准序列包含有第I+1至第J个下行通道对应的下行频域校准序列，则从第1个下行综合频域校准序列中提取第1至第I个下行通道对应的下行频域校准序列，从第2个下行综合频域校准序列提取第I+1至第J个下行通道对应的下行频域校准序列，然后根据提取的每个下行频域校准序列，计算对应的下行通道(第1至第J个下行通道)的补偿值。
本实施例中，所述根据预设策略将待校准的下行通道分为多组较佳地可以采用两种方式，其中第一种为：根据预算策略将待校准的N个下行通道分为N/M组，每组包括M个下行通道。采用这种方式完成对N个下行通道的在线校准时间只需N/M*HTDD帧，其中HTDD帧代表一个TDD帧时间，相对单次单天线下行通道在线校准，校准时间缩短了M倍。由于对每个下行通道的补偿值计算均以下行参考通道的幅度和相位作为参考基
准，下行参考通道的时变特性会引入误差，在下行参考通道的时变特性不是很剧烈时，误差较小，可以采用这种方式。第二种为：根据预算策略将待校准的N个下行通道分为N/M+1组，每组包括M个下行通道，每组包括一个下行参考通道。采用这种方式完成对N个下行通道的在线校准时间只需(N/M+1)*HTDD帧，其中HTDD帧代表一个TDD帧时间，相比第一种方式多用了一个TDD帧时间，但相对单次单天线下行通道在线校准，大大地缩短了校准时间；但由于每组均包含下行参考通道，相比第一种方式可以最大限度地消除下行参考通道的时变特性带来的误差，大大地提高了下行通道的校准精度。
上述实施例所提供的智能天线下行通道校准的方法，通过根据下行校准指令，为每个待校准的下行通道分配相应的下行时域校准序列；在后续每个下行GAP间隙期间，同时获取多个待校准的下行通道对应的下行时域校准序列，将所获取的每个下行时域校准序列发送至对应的下行通道，直至分配的所有下行时域校准序列发送完毕；针对所述每个下行GAP间隙，实时收集经过每个下行通道的下行时域校准序列；对收集的所述下行时域校准序列进行耦合处理，生成下行综合时域校准序列；将所述下行综合时域校准序列发送至下行校准通道；将经过下行校准通道的下行综合时域校准序列转换为下行综合频域校准序列，并缓存所述下行综合频域校准序列；根据缓存的所有下行综合频域校准序列计算待校准的下行通道的补偿值，根据所述补偿值对每个待校准的下行通道进行在线校准的方式，在不影响下行通道的正常工作前提下，相比单次单天线下行通道校准，大大缩短了智能天线下行通道的校准时间，提高了智能天线下行通道的校准效率。
此外，本发明实施例还提供一种存储介质，该存储介质包括一组指令，当执行所述指令时，引起至少一个处理器执行上文所述的操作。
本发明实施例还提供一种智能天线下行通道校准的***。参照图2，图
2为本发明的智能天线下行通道校准的***一实施例的功能模块示意图。在该实施例中，所述***100包括：下行校准序列分配模块110、下行校准序列发送模块120、下行校准序列处理模块130、下行通道校准模块140。其中，
所述下行校准序列分配模块110，配置为根据下行校准指令，为每个待校准的下行通道分配相应的下行时域校准序列；
所述下行校准序列发送模块120，配置为在后续每个下行GAP间隙期间，同时获取多个待校准的下行通道对应的下行时域校准序列，将所获取的每个下行时域校准序列发送至对应的下行通道，直至分配的所有下行时域校准序列发送完毕；
所述下行校准序列处理模块130，配置为针对所述每个下行GAP间隙，实时收集经过每个下行通道的下行时域校准序列；对收集的所述下行时域校准序列进行耦合处理，生成下行综合时域校准序列；将所述下行综合时域校准序列发送至下行校准通道；将经过下行校准通道的下行综合时域校准序列转换为下行综合频域校准序列，并缓存所述下行综合频域校准序列；
所述下行通道校准模块140，配置为根据缓存的所有下行综合频域校准序列计算待校准的下行通道的补偿值，根据所述补偿值对每个待校准的下行通道进行在线校准。
本实施例中下行校准序列分配模块110在接收到用户输入的下行校准指令，首先会计算待校准的下行通道的个数，然后根据待校准的下行通道的个数分配相应个数的下行时域校准序列。
本实施例中，同一所述下行GAP间隙发送的每个下行时域校准序列携带有区别本下行GAP间隙发送的其他下行时域校准序列的下行通道标识，以使根据该下行通道标识即可知晓该下行时域校准序列对应哪个下行通道。其中本实施例可以为同一下行GAP间隙发送的下行时域校准序列分配
不同相位，以相位作为区别同一下行GAP间隙发送的其他下行时域校准序列的下行通道标识，例如同一下行GAP间隙发送的相邻的下行时域校准序列依次相差2π/M的相位。
本实施例中，为了缩短对所有待校准的下行通道的校准时间以及不影响待校准的下行通道正常运行TDD业务，通过下行校准序列发送模块120在后续的下行GAP间隙期间向下行通道发送相应的下行时域校准序列，且在一个下行GAP间隙期间同时向多个待校准的下行通道发送相应的下行时域校准序列。当待校准的下行通道数量过多，不适宜在同一个下行GAP间隙向所有待校准的下行通道发送相应的下行时域校准序列时，需要对待校准的下行通道进行分组，将所有待校准的下行通道对应的下行校准序列通过多个下行GAP间隙发送，每个下行GAP间隙发送一组下行通道对应的下行校准序列。即当待校准的下行通道数量过大，还需根据预设策略将待校准的下行通道分为多组。参见图3，图3为本发明的智能天线下行通道校准的***另一实施例的功能模块示意图。所述的智能天线下行通道校准的***100还包括：下行通道分组模块150。
所述下行通道分组模块150，配置为根据预设策略将待校准的下行通道分为多组，每组包括多个下行通道。所述后续每个下行GAP间隙期间所获取的多个下行时域校准序列为所述多组下行通道中的一组下行通道对应的下行时域校准序列。即对待校准的下行通道进行分组后，则在后续的每个下行GAP间隙期间从所述多组下行通道对应的下行时域校准序列中选择一组下行通道的对应的下行时域校准序列，然后发送至相应的下行通道中，直至所有的下行时域校准序列发送完毕。所述多组下行通道中每组包括的下行通道个数可以相同也可以不同。
例如：待校准的下行通道为多个，在一个下行GAP间隙无法实现向所有待校准的下行通道同时发送相应的下行时域校准序列，则可以根据预设
策略将所述多个下行通道分为X组，每组包括多个下行通道，然后在接收下行校准指令之后X个下行GAP间隙发送相应的下行时域校准序列，如在接收下行校准指令之后的第1个下行GAP间隙向第1组待校准的下行通道发送相应的下行时域校准序列、在第2个下行GAP间隙向第2组待校准的下行通道发送相应的下行时域校准序列，……在第X个下行GAP间隙向第X组待校准的下行通道发送相应的下行时域校准序列。
本实施例中所述下行综合时域校准序列中包含有收集的每个时域校准序列信息。所述下行综合频域校准序列包含有与所述收集的每个时域校准序列对应的频域校准序列信息。本实施例将所述下行综合时域校准序列发送至下行校准通道是为了使下行校准通道对所述下行综合时域校准序列进行相关处理，其中所述下行校准通道对下行综合时域校准序列进行处理采用的是现有方式，在此不再赘述。
本实施例中下行通道校准模块140在所有的下行时域校准序列均发送到相应的下行通道，且所有的下行综合频域校准序列均已缓存后，根据缓存的所有下行综合频域校准序列计算待校准的下行通道的补偿值，即从每个下行综合频域校准序列提取相应的下行频域校准序列，然后根据每个下行频域校准序列计算对应的下行通道的补偿值。例如所有待校准的下行通道为J个，缓存有2个下行综合频域校准序列，其中第1个下行综合频域校准序列包含有第1至第I个下行通道对应的下行频域校准序列，第2个下行综合频域校准序列包含有第I+1至第J个下行通道对应的下行频域校准序列，则从第1个下行综合频域校准序列中提取第1至第I个下行通道对应的下行频域校准序列，从第2个下行综合频域校准序列提取第I+1至第J个下行通道对应的下行频域校准序列，然后根据提取的每个下行频域校准序列，计算对应的下行通道(第1至第J个下行通道)的补偿值。
本实施例中，所述下行通道分组模块150根据预设策略将待校准的下
行通道分为多组较佳地可以采用两种方式，其中第一种为：根据预算策略将待校准的N个下行通道分为N/M组，每组包括M个下行通道。采用这种方式完成对N个下行通道的在线校准时间只需N/M*HTDD帧，其中HTDD帧代表一个TDD帧时间，相对单次单天线下行通道在线校准，校准时间缩短了M倍。由于对每个下行通道的补偿值计算均以下行参考通道的幅度和相位作为参考基准，下行参考通道的时变特性会引入误差，在下行参考通道的时变特性不是很剧烈时，误差较小，可以采用这种方式。第二种为：根据预算策略将待校准的N个下行通道分为N/M+1组，每组包括M个下行通道，每组包括一个下行参考通道。采用这种方式完成对N个下行通道的在线校准时间只需(N/M+1)*HTDD帧，其中HTDD帧代表一个TDD帧时间，相比第一种方式多用了一个TDD帧时间，但相对单次单天线下行通道在线校准，大大地缩短了校准时间。但由于每组均包含下行参考通道，相比第一种方式可以最大限度地消除下行参考通道的时变特性带来的误差，大大地提高了下行通道的校准精度。
上述实施例所提供的智能天线下行通道校准的***，通过根据下行校准指令，为每个待校准的下行通道分配相应的下行时域校准序列；在后续每个下行GAP间隙期间，同时获取多个待校准的下行通道对应的下行时域校准序列，将所获取的每个下行时域校准序列发送至对应的下行通道，直至所述分配的所有下行时域校准序列发送完毕；针对所述每个下行GAP间隙，实时收集经过每个下行通道的下行时域校准序列；对收集的所述下行时域校准序列进行耦合处理，生成下行综合时域校准序列；将所述下行综合时域校准序列发送至下行校准通道；将经过下行校准通道的下行综合时域校准序列转换为下行综合频域校准序列，并缓存所述下行综合频域校准序列；根据缓存的所有下行综合频域校准序列计算待校准的下行通道的补偿值，根据所述补偿值对每个待校准的下行通道进行在线校准的方式，在
不影响下行通道的正常工作前提下，相比单次单天线下行通道校准，大大缩短了智能天线下行通道的校准时间，提高了智能天线下行通道的校准效率。
本发明实施例另提供一种智能天线上行通道校准的方法。参照图4，图4为本发明的智能天线上行通道校准的方法一实施例的流程示意图。在该实施例中，所述方法包括：
步骤S101、根据上行校准指令，在后续的一个GAP间隙期间向上行校准通道发送上行时域校准序列；
本实施例中在接收到用户输入的上行校准指令后，会在后续的一个GAP间隙获取一个上行时域校准序列，并将该上行时域校准序列发送至上行校准通道，以使上行校准通道对实施上行时域校准序列进行相关处理，本实施例中所述上行校准通道采用现有的方式对上行时域校准序列进行处理，在此不再赘述。
步骤S102、在所述GAP间隙期间，获取经过上行校准通道的上行时域校准序列，根据待校准的上行通道的个数K对所述上行时域校准序列进行一分多耦合处理，生成K个上行时域校准序列，向K个待校准的上行通道分别发送1个所述上行时域校准序列；
本步骤S102中生成的K个上行时域校准序列相同，无需进行区分。
步骤S103、将经过每个上行通道的上行时域校准序列转换为相应的上行频域校准序列；
本实施例中由于每个上行通道当前的幅度、相位不同，因此相同的上行时域校准序列经过每个上行通道之后都会发生变化，经过不同的上行通道发生的变化可能相同也可能不同，因此经过每个上行通道的上行时域校准序列可能相同也可能不同。
步骤S104、根据每个上行通道的上行频域校准序列计算相应的上行通
道的补偿值，根据所述补偿值对每个上行通道进行在线校准。
本步骤S104根据每个上行通道的上行频域校准序列可计算出每个上行通道的幅度、相位的变化量，从而可以计算出每个上行通道的补偿值。
上述实施例所提供的智能天线上行通道校准的方法，通过根据上行校准指令，在后续的一个GAP间隙期间向上行校准通道发送上行时域校准序列；在所述GAP间隙期间，获取经过上行校准通道的上行时域校准序列，根据待校准的上行通道的个数K对所述上行时域校准序列进行一分多耦合处理，生成K个上行时域校准序列，向K个待校准的上行通道分别发送1个所述上行时域校准序列；将经过每个上行通道的上行时域校准序列转换为相应的上行频域校准序列；根据每个上行通道的上行频域校准序列计算相应的上行通道的补偿值，根据所述补偿值对每个上行通道进行在线校准的方式，在不影响上行通道的正常工作前提下，相比单次单天线上行通道校准，大大缩短了智能天线上行通道的校准时间，提高了智能天线上行通道的校准效率。

本实施例中所述生成的N个上行时域校准序列相同，无需进行区分。由于每个上行通道当前的幅度、相位不同，因此相同的上行时域校准序列经过每个上行通道之后都会发生变化，经过不同的上行通道发生的变化可能相同也可能不同，因此经过每个上行通道的上行时域校准序列可能相同也可能不同。
