Description

一种校正方法及通信设备 技术领域
本发明实施例涉及通信技术领域，具体涉及一种校正方法及通信设备。
背景技术
校正技术在无线通信系统中被广泛使用，如多通道无线通信设备、分布式无线通信系统等。其中，校正主要是指对基站的收发通道的相位或幅度的校正，通常包括中射频或者基带部分。为了保证良好的无线网络性能，要求无线通信系统中的各通信设备协同工作。然而，由于每个通信设备所处环境和工作参数可能不同，因此，为了各通信设备能够协同工作，需要缩短校正周期，以加快校正速率。目前，一种常用的校正方式为：将通信设备按照区域进行划分，处于同一区域内的通信设备结合时分复用和频分复用，而不同区域的设备，使用区域之间的空间隔离效果进行频分复用。然而，由于上述方式中每个周期均是针对全工作频率范围进行校正的，以致频分复用的频率校正组合的数量有限，当通信设备的数量较多时，将限制校正速率的进一步提高。
发明内容
本发明实施例公开了一种校正方法及通信设备，用于提高校正速率。
第一方面公开了一种校正方法，该方法应用于通信设备，将工作频率划分为包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的频率组合的至少三个频率组合，当目标设备满足第一预设条件，即目标设备的当前条件满足触发目标设备进行全工作频率范围校正的条件时，从至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，向目标设备发送用于指示目标设备使用第一频率组合进行全工作频率范围校正的第一指示信息，当目标设备满足第二预设条件，即目标设备的当前条件满足触发目标设备进行部分工作频率范围校正的条件时，从至少两个用于部分工作频率范围校正的频率组合中选取第二频率组合，向目标设备发送用于指示目标 设备使用第二频率组合进行部分工作频率范围校正的第二指示信息，目标设备为通信设备管理的任一无线通信设备。可见，将全工作频率范围校正和部分工作频率范围校正进行了组合，且多个无线通信设备可以进行并行校正，可以提高校正频率的利用率，从而可以提高校正速率和缩短校正周期。其中，第一预设条件即触发全工作频率范围校正的条件，第二预设条件即触发部分工作频率范围校正的条件。
在一个实施例中，可以根据通信设备管理的无线通信设备的工作参数，设置用于指示通信设备管理的无线通信设备进行至少一次全工作频率范围校正的第一校正周期和用于指示通信设备管理的无线通信设备进行部分工作频率范围校正的第二校正周期。第一校正周期大于第二校正周期，可见，设置了用于触发全工作频率范围校正的长周期和用于触发部分工作频率范围校正的短周期，从而，可以保证无线通信设备根据这些校正触发方式进行有效的校正。
在一个实施例中，当当前时间与第一时间之间的时间差等于第一校正周期，或目标设备的工作参数为第一预设值时，表明目标设备满足第一预设条件，即目标设备的当前条件满足触发目标设备进行全工作频率范围校正的条件，第一时间是目标设备上一次由第一校正周期触发进行全工作频率范围校正的时间；当当前时间与第二时间之间的时间差等于第二校正周期时，表明目标设备满足第二预设条件，即目标设备的当前条件满足触发目标设备进行部分工作频率范围校正的条件，第二时间是目标设备上一次由第二校正周期触发进行部分工作频率范围校正的时间。可见，设置了用于触发全工作频率范围校正的长周期和用于触发部分工作频率范围校正的短周期，此外，还设置用于触发全工作频率范围校正的事件触发机制，从而，可以保证无线通信设备根据这些校正触发方式进行有效的校正。
在一个实施例中，当目标设备满足第一预设条件时，可以先判断至少一个用于全工作频率范围校正的频率组合中是否存在空闲的频率组合，当至少一个用于全工作频率范围校正的频率组合中存在空闲的频率组合时，将从这些空闲的频率组合中选取第一频率组合，以便目标设备可以快速的使用第一频率组合进行全工作频率范围校正；当至少一个用于全工作频率范围校正的频率组合中不存在空闲的频率组合时，可以为目标设备分配用于执行全工作频率范围校正的时间，以及从至少一个用于全工作频率范围校正的频率组合中选取第一频率 组合，以便目标设备在分配的时间使用第一频率组合进行全工作频率范围校正，可见，可以对频率资源和无线通信设备进行合理的管理，以避免多个无线通信设备进行全工作频率范围校正时产生干扰，从而，可以提高校正频率资源利用率。
在一个实施例中，根据通信设备管理的无线通信设备的工作参数设置第一校正周期，可以是获取通信设备管理的无线通信设备的工作参数变化第二预设值时所需的第一时长，获取无线通信设备的工作参数的设置周期，将第一时长和设置周期中的较小值设置为第一校正周期；根据通信设备管理的无线通信设备的工作参数设置第二校正周期，可以是获取通信设备管理的无线通信设备的工作参数变化第三预设值时所需的第二时长，并将第二时长设置为第二校正周期。可见，第一校正周期和第二校正周期是根据无线通信设备的工作参数设置的，而不是随意设置的，因此，可以提高设置校正周期的准确性。其中，第二预设值大于第三预设值，第一时长大于第二时长。
在一个实施例中，当检测到目标设备根据第一指示信息校正完时，或当检测到目标设备根据第二指示信息校正完时，可以从目标设备获取校正结果，并根据校正结果调整目标设备的通道参数，以便保证无线通信设备的通道参数的偏差较小，从而可以保证无线通信设备工作的稳定性。
第二方面公开一种通信设备，该通信设备包括用于执行第一方面或第一方面的任一种可能实现方式所提供的校正方法的单元。
第三方面公开一种通信设备，包括处理器、存储器和收发器，存储器用于存储组程序代码，处理器用于执行程序代码，收发器用于与无线通信设备进行通信。当处理器执行存储器存储的程序代码时，使得处理器执行第一方面或第一方面的任一种可能实现方式所公开的校正方法。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开了一种校正方法及通信设备，用于提高校正速率。以下分别进行详细说明。
为了更好地理解本发明实施例公开的一种校正方法及通信设备，下面先对本发明实施例使用的网络架构进行描述。请参阅图1，图1是本发明实施例公开的一种网络架构示意图。如图1所示，该网络架构可以包括通信设备101和至少两个无线通信设备102，通信设备101可以与这至少两个无线通信设备102进行通信，用于管理和调度这至少两个无线通信设备102。具体地，通信设备101，用于为这至少两个无线通信设备102分配校正频率和分发校正指令；这至少两个无线通信设备102，用于接收通信设备101发送的校正指令，根据校正指令进行频率校正，并将校正结果发送给通信设备101；通信设备101，还用于根据这至少两个无线通信设备102的校正结果调整这至少两个无线通信设备102的通道参数。其中，通信设备101和这至少两个无线通信设备102上均设置有天线，天线，用于接收空口信号(即电磁信号)，将空口信号转换为电信号，以及将电信号转换为空口信号并进行发送。
基于图1所示的网络架构，请参阅图2，图2是本发明实施例公开的一种校正方法的流程示意图。其中，该校正方法是从通信设备101和无线通信设备102的角度来描述的。如图2所示，该校正方法可以包括以下步骤。
201、通信设备将工作频率划分为包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的频率组合的至少三个频率组合。
本实施例中，当通信设备对无线通信设备进行校正管理和校正资源调度时，可以先将管理的可使用校正频率资源进行划分，即将能够使用的频率划分为用于全工作频率范围校正的频率组合和用于部分工作频率范围校正的频率组合。其中，为了保证通信设备管理的每个无线通信设备可以并行进行部分频率范围校正，划分的用于部分工作频率范围校正的频率组合的数量要等于通信设备管理的无线通信设备的数量，例如：当通信设备管理了十个无线通信设备时，划分后的频率组合中要保证有十个用于部分工作频率范围校正的频率组合。此外，为了保证无线通信设备能够进行全工作频率范围校正，划分后的频率组合中必须包括至少一个用于全工作频率范围校正的频率组合。当频率组合的数量较少时，在保证用于部分工作频率范围校正的频率组合的数量要等于通信设备管理的无线通信设备的数量的情况下，用于全工作频率范围校正的频率组合可以为一个；当频率组合的数量较多时，在保证用于部分工作频率范围校正的频率组合的数量要等于通信设备管理的无线通信设备的数量的情况下，用于全工作频率范围校正的频率组合可以为多个，以便多个无线通信设备可以并行进行全工作频率范围校正，从而可以提高频率资源的利用率。
202、当目标设备满足第一预设条件时，通信设备从至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，并向目标设备发送用于指示目标设备使用第一频率组合进行全工作频率范围校正的第一指示信息。
本实施例中，通信设备将工作频率划分为包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的频率组合的至少三个频率组合之后，通信设备将实时或周期性地监测管理的无线通信设备，当监测到目标设备满足第一预设条件，即监测到目标设备的当前条件满足触发目 标设备进行全工作频率范围校正的条件时，通信设备可以从至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，并向目标设备发送用于指示目标设备使用第一频率组合进行全工作频率范围校正的第一指示信息。其中，目标设备为通信设备管理的任一无线通信设备。
在一个实施例中，当监测到目标设备满足第一预设条件，即监测到目标设备的当前条件满足触发目标设备进行全工作频率范围校正的条件时，可以先判断至少一个用于全工作频率范围校正的频率组合中是否存在空闲的频率组合，即判断至少一个用于全工作频率范围校正的频率组合是否被全部使用，当至少一个用于全工作频率范围校正的频率组合中存在空闲的频率组合时，表明至少一个用于全工作频率范围校正的频率组合还有未被使用的频率组合，将从未被使用的频率组合选择第一频率组合，并向目标设备发送用于指示目标设备使用第一频率组合进行全工作频率范围校正的第一指示信息，以便目标设备马上使用第一频率组合进行全工作频率范围校正。当至少一个用于全工作频率范围校正的频率组合中不存在空闲的频率组合时，表明至少一个用于全工作频率范围校正的频率组合全部被使用，也即是表明目标设备当前无法进行全工作频率范围校正，如果目标设备当前进行全工作频率范围校正的话，将会对使用同一频率组合进行全工作频率范围的另一无线通信设备产生干扰，因此，可以为目标设备分配用于执行全工作频率范围校正的时间，以及从至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，并向目标设备发送用于指示目标设备使用第一频率组合在分配的时间进行全工作频率范围校正的第一指示信息，以便目标设备在分配的时间使用第一频率组合进行全工作频率范围校正。因此，可以实现对用于全工作频率范围校正的频率组合的合理管理，以避免多个无线通信设备进行全工作频率范围校正时产生干扰。
203、当目标设备满足第二预设条件时，通信设备从至少两个用于部分工作频率范围校正的频率组合中选取第二频率组合，并向目标设备发送用于指示目标设备使用第二频率组合进行部分工作频率范围校正的第二指示信息。
本实施例中，通信设备将工作频率划分为包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的频率组合的至少三个频率组合之后，通信设备将实时或周期性地监测管理的无线通信设备，当 监测到目标设备满足第二预设条件，即监测到目标设备的当前条件满足触发目标设备进行部分工作频率范围校正的条件时，通信设备从至少两个用于部分工作频率范围校正的频率组合中选取第二频率组合，并向目标设备发送用于指示目标设备使用第二频率组合进行部分工作频率范围校正的第二指示信息，以便目标设备马上使用第二频率组合进行部分工作频率范围校正。其中，每个无线通信设备每次进行部分工作频率范围校正所使用的频率组合可以是固定不变的，也可以是周期性变化的，还可以是不断变化的，本实施例不作限定。
204、目标设备根据第一指示信息进行全工作频率范围校正，或根据第二指示信息进行部分工作频率范围校正。
本实施例中，目标设备接收到第一指示信息或第二指示信息之后，将根据第一指示信息使用第一频率组合进行全工作频率范围校正，或者根据第二指示信息使用第二频率组合进行部分工作频率范围校正，即计算目标设备的工作参数与上一次校正完时目标设备的工作参数之间的误差。其中，工作参数可以包括温度、带宽、频率等中的至少一种。
在图2所描述的校正方法中，通信设备将工作频率划分为包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的频率组合的至少三个频率组合，当目标设备满足第一预设条件时，从至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，并向目标设备发送用于指示目标设备使用第一频率组合进行全工作频率范围校正的第一指示信息，当目标设备满足第二预设条件时，从至少两个用于部分工作频率范围校正的频率组合中选取第二频率组合，并向目标设备发送用于指示目标设备使用第二频率组合进行部分工作频率范围校正的第二指示信息，可见，将全工作频率范围校正和部分工作频率范围校正进行了组合，且多个无线通信设备可以进行并行校正，可以提高校正频率的利用率，从而可以提高校正速率和缩短校正周期。
基于图1所示的网络架构，请参阅图3，图3是本发明实施例公开的另一种校正方法的流程示意图。其中，该校正方法是从通信设备101和无线通信设备102的角度来描述的。如图3所示，该校正方法可以包括以下步骤。
301、通信设备将工作频率划分为包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的频率组合的至少三个频率组合。
其中，步骤301与前面实施例中的步骤201相同，本实施例此处不作赘述。
302、通信设备根据通信设备管理的无线通信设备的工作参数，设置用于指示通信设备管理的无线通信设备进行至少一次全工作频率范围校正的第一校正周期和用于指示通信设备管理的无线通信设备进行部分工作频率范围校正的第二校正周期。
本实施例中，通信设备可以根据通信设备管理的无线通信设备的工作参数，设置用于指示通信设备管理的无线通信设备进行至少一次全工作频率范围校正的第一校正周期和用于指示通信设备管理的无线通信设备进行部分工作频率范围校正的第二校正周期。其中，第一校正周期用于周期性触发无线通信设备进行全工作频率范围校正，第二校正周期用于周期性触发无线通信设备进行部分工作频率范围校正。第一校正周期大于第二校正周期，以便保证在第一校正周期内进行了多次部分工作频率范围校正。此外，通信设备还设置了用于进行事件触发无线通信设备进行全工作频率范围校正的事件触发条件，当目标设备的工作参数为第一预设值时，表明目标设备的当前条件满足事件触发目标设备进行全工作频率范围校正的触发条件。其中，目标设备的工作参数包括温度。
本实施例中，可以获取通信设备管理的无线通信设备的工作参数变化第二预设值时所需的第一时长，以及获取无线通信设备的工作参数的设置周期，将第一时长和设置周期中的较小值设置为第一校正周期。此外，可以获取通信设备管理的无线通信设备的工作参数变化第三预设值时所需的第二时长，并将第二时长设置为第二校正周期，第二预设值大于第三预设值，第一时长大于第二时长，以便保证第一校正周期大于第二校正周期。
举例说明，当无线通信设备的温度小于A时，无线通信设备的工作频率与无线通信设备的工作参数近似无关，当无线通信设备的温度大于或等于A且小于B时，无线通信设备的工作频率与无线通信设备的工作参数近似呈线性变化，当无线通信设备的温度大于或等于B时，无线通信设备的工作频率与无线通信设备的工作参数呈非线性变化。可见，当无线通信设备的温度大于 或等于A且小于B时，无线通信设备的工作频率会影响无线通信设备的工作参数，但此时的影响较小，可以将无线通信设备的温度达到A时所需的工作时长设置为第二校正周期；当无线通信设备的温度大于或等于B时，无线通信设备的工作频率会影响无线通信设备的工作参数，此时的影响较大，同时无线通信设备的工作参数是周期性设置的，可以将无线通信设备的温度达到B是所需的工作时长与无线通信设备的工作参数的设置周期中较小的值设置为第一校正周期。当每个无线通信设备的A值和B值不同，或者每个无线通信设备的温度达到A和B所需的工作时长不同时。可以均衡考虑各个无线通信设备，可以是计算所有无线通信设备的平均值，也可以是按照权重进行计算，还可以是通过其它方式进行计算。
303、当目标设备满足第一预设条件时，通信设备从至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，并向目标设备发送用于指示目标设备使用第一频率组合进行全工作频率范围校正的第一指示信息。
本实施例中，目标设备满足第一预设条件，可以是当前时间与第一时间之间的时间差等于第一校正周期，第一时间是目标设备上一次由第一校正周期触发进行全工作频率范围校正的时间，即目标设备的当前条件满足周期性触发目标设备进行全工作频率范围校正的条件；也可以是目标设备的工作参数为第一预设值，即目标设备的当前条件满足事件触发目标设备进行全工作频率范围校正的条件。其中，第一预设值可以是上面提到的B值。
其中，步骤303与前面实施例中的步骤202相同，本实施例此处不作赘述。
304、当目标设备满足第二预设条件时，通信设备从至少两个用于部分工作频率范围校正的频率组合中选取第二频率组合，并向目标设备发送用于指示目标设备使用第二频率组合进行部分工作频率范围校正的第二指示信息。
本实施例中，目标设备满足第二预设条件，可以是当前时间与第二时间之间的时间差等于第二校正周期，第二时间是目标设备上一次由第二校正周期触发进行部分工作频率范围校正的时间，即目标设备的当前条件满足周期性触发目标设备进行部分工作频率范围校正的条件。
其中，步骤304与前面实施例中的步骤203相同，本实施例此处不作赘述。
305、目标设备根据第一指示信息进行全工作频率范围校正，或根据第二 指示信息进行部分工作频率范围校正。
其中，步骤305与前面实施例中的步骤204相同，本实施例此处不作赘述。
306、目标设备将校正结果发送给通信设备。
本实施例中，目标设备根据第一指示信息或第二指示信息校正完之后，可以将校正结果主动发送给通信设备；也可以是在接收到通信设备发送的用于指示反馈校正结果的指示信息之后，将校正结果发送给通信设备。
307、通信设备根据校正结果生成用于指示目标设备调整通道参数的第三指示信息并发送给目标设备。
本实施例中，通信设备接收到目标设备发送的校正结果之后，将根据校正结果生成用于指示目标设备调整通道参数的第三指示信息，并将第三指示信息发送给目标设备。
本实施例中，当校正结果为全工作频率范围校正的校正结果时，将直接使用校正结果，即直接根据校正误差量Err(f)计算校正系数Cal(f)。其中，f是频率，Err(f)表示误差随频率的变化关系，Cal(f)表示校正系数随频率的变化关系。之后根据校正系数Cal(f)生成用于指示目标设备调整通道参数的第三指示信息并发送给目标设备。
本实施例中，当校正结果为部分工作频率范围校正的校正结果时，如果Err(f1)近似等于Err(f2)，即(Err(f1)-Err(f2))/F*(f1-f2)满足全工作频率范围校正的校正误差要求，则直接根据校正误差Eff(f1/f2)计算全工作频率范围的校正系数Cal(f)，f1和f2是两个具体的频率值，F表示全工作频率范围。如果Err(f1)不近似等于Err(f2)，即Err(f1)与Err(f2)相差较大，则先计算R＝(Err(f1)-Err(f2))/(f1-f2)，根据R计算全工作频率范围的校正误差量Err(f)＝R*Err(f1)*(f-f1)，之后根据全工作频率范围的校正误差量Err(f)计算全工作频率范围的校正系数Cal(f)。之后根据全工作频率范围的校正系数Cal(f)生成用于指示目标设备调整通道参数的第三指示信息并发送给目标设备。
308、目标设备根据第三指示信息调整目标设备的通道参数。
本实施例中，目标设备接收到通信设备发送的第三指示信息之后，将根据 第三指示信息调整通道参数。其中，目标设备的通道参数可以包括相位和幅度。
在图3所描述的校正方法中，通信设备将工作频率划分为包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的频率组合的至少三个频率组合，当目标设备满足第一预设条件时，从至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，并向目标设备发送用于指示目标设备使用第一频率组合进行全工作频率范围校正的第一指示信息，当目标设备满足第二预设条件时，从至少两个用于部分工作频率范围校正的频率组合中选取第二频率组合，并向目标设备发送用于指示目标设备使用第二频率组合进行部分工作频率范围校正的第二指示信息，可见，将全工作频率范围校正和部分工作频率范围校正进行了组合，且多个无线通信设备可以进行并行校正，可以提高校正频率的利用率，从而可以提高校正速率和缩短校正周期。
基于图1所示的网络架构，请参阅图4，图4是本发明实施例公开的一种通信设备的结构示意图。如图4所示，该通信设备可以包括：
划分单元401，用于将工作频率划分为至少三个频率组合，至少三个频率组合包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的频率组合；
选取单元402，用于当目标设备满足第一预设条件时，从划分单元401划分的至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，目标设备为通信设备管理的任一无线通信设备；

通信单元403，还用于向目标设备发送用于指示目标设备使用选取单元402选取的第二频率组合进行部分工作频率范围校正的第二指示信息。
在图4所描述的通信设备中，通信设备将工作频率划分为包括至少一个用于全工作频率范围校正的频率组合和至少两个用于部分工作频率范围校正的 频率组合的至少三个频率组合，当目标设备满足第一预设条件时，从至少一个用于全工作频率范围校正的频率组合中选取第一频率组合，并向目标设备发送用于指示目标设备使用第一频率组合进行全工作频率范围校正的第一指示信息，当目标设备满足第二预设条件时，从至少两个用于部分工作频率范围校正的频率组合中选取第二频率组合，并向目标设备发送用于指示目标设备使用第二频率组合进行部分工作频率范围校正的第二指示信息，可见，将全工作频率范围校正和部分工作频率范围校正进行了组合，且多个无线通信设备可以进行并行校正，可以提高校正频率的利用率，从而可以提高校正速率和缩短校正周期。
基于图1所示的网络架构，请参阅图5，图5是本发明实施例公开的另一种通信设备的结构示意图。其中，图5所示的通信设备是由图4所示的通信设备优化得到的。其中，该通信设备还可以包括：
