目前，路由器可以包括多根天线，每根天线对应的天线路径的发送功率都相同，且每根天线对应的天线路径中传输的数据也一样，可以在不增加频谱资源和天线发射功率的条件下提高系统信道容量。
但是，在使用不同天线路径对携带有同一通信信号的电磁波进行传输时，该电磁波经过的传输路径(如，折射路径和/或反射路径等)也不同。因此，终端接收到的通信信号会有不同程度的信号衰落。而对于波长很短的电磁波，其携带的通信信号对应的信号衰落程度尤其明显，易导致路由器发送的通信信号无法被终端接收，降低了路由器与终端之间的通信效率。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚明白，下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
第六代无线网络技术(Wi-Fi 6)是Wi-Fi联盟基于电气与电子工程师协会(Institute of Electrical and Electronics Engineers，IEEE)的IEEE 802.11标准，创建的无线局域网技术。Wi-Fi 6可以允许设备与最多8个设备进行通信，且最高的理论通信速率可达9.6Gbps。并且，Wi-Fi 6路由器支持多天线功能，可以在不增加频谱资源和天线发射功率的条件下，提高路由器的通信信道容量。
但是，根据电磁波的物理特性，波长越短的电磁波在传输过程中的信号损耗越多，从而使具有短波长特性的Wi-Fi 6路由器对应的穿过障碍物的衰减变大，Wi-Fi 6路由器的穿墙能力远远低于2.4G频段的路由器。
如果把每个天线路径比做“公路”的话，有的公路畅通一些，有的公路拥堵一些。如果路由器知道这些“公路”的实时路况，在该路由器需要发送数据时，可以在畅通的“公路”上多发一些，在拥堵的“公路”少发一些，从而优化数据的发送方式，提升数据的传输速率。
图1示出本申请实施例提供的通信信号的传输方法的流程示意图。该通信信号的传输方法可应用于通信信号的传输装置，该通信信号的传输装置可以设置于基站或路由器中。如图1所示，本申请实施例中的通信信号的传输方法包括但不限于以下步骤。
步骤S101，依据获取到的至少两个天线路径的信道质量，确定至少两个天线路径中各天线路径对应的传输参数。
步骤S102，依据至少两个天线路径中各天线路径对应的传输参数，在至少两个天线路径上向终端传输通信信号。
在本实施例中，通过获取至少两个天线路径的信道质量，实现对至少两个天线路径的信道质量的监控，能够快速对不同的天线路径采取不同的调整方式，以适应不同的传输路径(如，折射路径和/或反射路径等)的传输要求；依据获取到的至少两个天线路径的信道质量，确定至少两个天线路径中各天线路径对应的传输参数，能够使各天线路径对应的传输参数更符合通信信号的传输需求，从而提升通信信号的传输质量；依据天线路径对应的传输参数，在至少两个天线路径上向终端传输通信信号，能够减少因电磁波的波长很短，所带来的信号衰落的问题，动态的调整各个天线路径的传输参数，提升通信设备之间通信效率。
其中，在至少两个天线路径上向终端传输通信信号，可以是使用至少两个天线路径同时 向终端发送通信信号；也可以是使用至少两个天线路径，周而复始的依次向终端发送通信信号，即按照次序周而复始地一个天线路径接替一个天线路径的传输通信信号。
对于任意一个天线路径而言，其传输的通信信号可以是待传输通信信号的一部分，由多个天线路径共同完成待传输通信信号的传输；也可以由多个天线路径中通信等级高的天线路径来传输全部的待传输通信信号，从而提升通信设备的通信效率。
在某一时刻，以固定发送功率分别在多个天线路径上发送相同的探测请求消息，以使不同的移动终端能够根据不同的天线路径中接收到的通信信号的信号强度，确定不同天线路径对应的信道质量；移动终端可以根据不同天线路径对应的信道质量、移动终端的标识以及该移动终端所处的实时位置信息等，生成探测响应消息，并发送该探测响应消息给路由器。当路由器获得不同的移动终端反馈的各个天线路径对应的信道质量时，可以获知不同的天线路径对应的信道质量，进而通过对不同的天线路径对应的传输参数进行调整，使不同的天线路径对应的调整后的传输参数更符合通信信号的传输需求。
例如，使信道质量好的天线路径可以拥有更好的通信资源，以提升通信信号的传输质量和传输速率。还能够使信道质量差的天线路径减少对通信资源的占用，提升通信资源的利用效率。
在一实施例中，通信信号承载的通信信息，包括：下行业务信息。例如，下行业务信息可以包括：下载视频文件、语音数据和图像数据中的至少一种信息。
通过动态的监控每个天线路径和移动终端的信道质量等信息，动态调整每个天线路径对应传输参数，实现移动终端的实时位置和路由器的多个天线路径的动态匹配，提升移动终端的下行业务信息的处理速度。
本申请实施例还提供另一种实施方式，其中，步骤S101中的依据获取到的至少两个天线路径的信道质量，确定至少两个天线路径中各天线路径对应的传输参数，可以采用如下方式实现。
依据至少两个天线路径的信道质量和预设信道质量阈值，确定至少两个天线路径中各天线路径对应的通信等级；依据至少两个天线路径中各天线路径的通信等级，确定至少两个天线路径中各天线路径对应的传输参数。
例如，若至少两个天线路径中的某个天线路径的信号质量超过预设信道质量阈值，可确定该天线路径对应的通信等级较高，即该天线路径对应的通信质量较好。反之，若至少两个天线路径中的某个天线路径的信号质量低于预设信道质量阈值，可确定该天线路径对应的通信等级较低，即该天线路径对应的通信质量较差。
通过依据至少两个天线路径的各天线路径的通信等级，确定至少两个天线路径中各天线路径对应的传输参数，对不同的天线路径采取不同的调整方式，以适应不同的传输路径的传输要求，能够使不同的天线路径(如，折射路径和/或反射路径等)对应的信道传输性能得到提升，从而使至少两个天线路径中各天线路径更适合传输特定的通信信号，提升通信效率。
在一实施例中，传输参数的数值与天线路径对应的通信等级成正比。
例如，传输参数的数值越大，则对应的天线路径对应的通信等级越高，表征该天线路径对应的通信质量越好。反之，若传输参数的数值越小，则对应的天线路径对应的通信等级越低，表征该天线路径对应的通信质量越差。
通过传输参数的数值与天线路径对应的通信等级之间的对应关系，能够准确方便的对不 同的天线路径对应的传输参数进行调整，以适应不同的通信信号的传输需求，提升通信信号的传输效率。
在一实施例中，依据至少两个天线路径中各天线路径的通信等级，确定至少两个天线路径中各天线路径对应的传输参数，包括：依据预设参数阈值和至少两个天线路径中各天线路径对应的通信等级，分别对至少两个天线路径中各天线路径的预设传输参数进行调整，生成至少两个天线路径中各天线路径对应的目标传输参数。
其中，预设传输参数是预先设置的、天线路径对应的传输参数的最低标准参数。
通过该预设传输参数也能够在天线路径中传输通信信号，但不同的天线路径(如，折射路径和/或反射路径等)对应的信道衰减不同，因此，基于预设参数阈值和至少两个天线路径中各天线路径对应的通信等级，分别对至少两个天线路径中各天线路径的预设传输参数进行调整，能够使不同的天线路径可以获得与其折射特性和/或反射特性相匹的目标传输参数，提升天线路径的传输性能。
例如，可以为通信等级较高的天线路径，匹配更优的传输参数，例如，更宽的传输带宽，和/或，更高的发射功率等，以使该通信等级较高的天线路径能够获得更多的通信资源，提升该天线路径对通信信号的传输效率。
对应的，可以降低通信等级较低的天线路径对应的传输参数，例如，减少该通信等级较低的天线路径的传输带宽，以获得目标传输带宽；和/或，降低该通信等级较低的天线路径的发射功率，以获得目标发射功率，使通信资源能够被合理利用，提升通信效率。
在一实施例中，传输参数，包括：通信信号中的数据符号对应的调制编码比特的数量、天线路径对应的发射功率和至少两个天线路径对应的传输带宽中的至少一种。
其中，通信信号中的数据符号对应的调制编码比特的数量是路由器的射频收发芯片在对数据符号进行调整编码时所使用的二进制字符的数量。天线路径对应的发射功率可以存储在路由器的存储器中，以方便射频收发芯片的调用。传输带宽用于表征天线路径对应的通信信号传输的数据传输能力，能够标识单位时间内通过该天线路径的通信链路的数据量。
通过不同维度的参数来表征传输参数，能够使天线路径的通信传输性能获得更全面的衡量，从而对不同维度的传输参数进行调整，以使调整后的传输参数可以更适用于通信信号的传输需求，提升天线路径的传输效率。
在一实施例中，针对通信信号中的数据符号的调制方式，可以采用如下方式实现：依据预设调制算法对获取到的待传输的通信信号进行调制，获得调制后的通信信号；依据预设发射功率和预设传输带宽，在至少两路天线路径上传输调制后的通信信号。
其中，预设调制算法可以包括：模拟调制算法和/或数字调制算法。模拟调制算法包括：幅度调制(Amplitude Modulation，AM)算法、频率调制(Frequency Modulation，FM)算法。数字调制算法包括：振幅键控算法、移频键控算法、移相键控算法和正交幅度调制算法中的至少一种。
通过不同的预设调整算法，能够对待传输的通信信号进行调制，使调整后的通信信号方便传输；依据预设发射功率和预设传输带宽在至少两路天线路径上传输调制后的通信信号，能够使调整后的通信信号快速被终端接收到，使终端可以快速获取其需要的信息。
在一实施例中，在执行步骤S102中的依据天线路径对应的传输参数，在至少两个天线路径上向终端传输通信信号之后，还可以根据终端的实时位置，对各个天线路径对应的传输参 数进行更新，以使更新后的传输参数更适应通信信号的传输需求。
图2示出本申请实施例提供的天线路径对应的传输参数的更新方法的流程示意图。该天线路径对应的传输参数的更新方法可应用于通信信号的传输装置，该通信信号的传输装置可以设置于基站或路由器中。如图2所示，本申请实施例中的天线路径对应的传输参数的更新方法包括但不限于以下步骤。
步骤S201，获取终端反馈的位置更新信息。
其中，位置更新信息包括：终端在更新后的位置上的至少两个天线路径的信道质量。
例如，位置更新信息中的更新后的位置可以是经纬度信息，也可以是某地标性建筑的位置信息等。通过该位置更新信息能够获知终端实时所处的位置信息，方便为终端匹配更优的天线路径。
位置更新信息不仅包括终端更新后的位置信息，还包括与该更新后的位置信息对应的至少两个天线路径的信道质量(例如，信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)、参考信号接收功率(Reference Signal Receiving Power，RSRP)等信息)，从而明确各个天线路径是否适合通信信号的传输。
步骤S202，依据位置更新信息，更新至少两个天线路径中各天线路径对应的传输参数。
其中，对于至少两个天线路径中各天线路径对应的传输参数的更新，可以采用本申请实施例中任一种确定天线路径对应的传输参数的方法来实现，例如，图1所示的步骤S101所示的方法等。
终端在位置变更的过程中，该终端与路由器之间的天线路径也会对应的发生变化，例如，折射路径中对应的折射点多了，和/或，反射路径中的障碍物增加等等。上述折射路径和/或反射路径的变更，使天线路径的信道质量也发生变化。因此，需要根据不同的终端在更新后的位置上的、至少两个天线路径的信道质量，对至少两个天线路径中各天线路径对应的传输参数进行调整，从而使调整后的传输参数能够更适用于通信信号的传输。
例如，对信道质量超过预设信道质量阈值的天线路径，可以提高该天线路径对应的发射功率、增加该天线路径对应的传输带宽，以及使用更高的调制编码比特的数量对该天线路径中传输的通信信号进行调整编码等，从而提升通信信号的传输质量。
又例如，还可以对信道质量小于预设信道质量阈值的天线路径，减少该天线路径对应的发射功率、降低该天线路径对应的传输带宽和降低调制编码比特的数量中的至少一种的调整方式，来对该信道质量差的天线路径对应的传输参数进行更新，使该信道质量差的天线路径不占用过多的通信资源，提升通信资源的利用效率。
在本实施例中，通过依据位置更新信息，更新至少两个天线路径中各天线路径对应的传输参数，能够使终端在实时位置发生变更的情况下，仍能够使用合适的至少两个天线路径对通信信号进行传输，并使至少两个天线路径对应的更新后的传输参数与终端所处的实时位置更匹配，使终端能够获得更有的通信服务，提升通信质量。
在一实施例中，在执行步骤S101中的依据获取到的至少两个天线路径的信道质量，确定至少两个天线路径中各天线路径对应的传输参数之前，还包括：使用至少两个天线路径同时向终端发送探测请求消息，或，使用至少两个天线路径依次向终端发送探测请求消息；响应于终端发送的探测响应消息，获取至少两个天线路径中各天线路径对应的信道质量。
其中，探测请求消息用于对天线路径的传输环境进行探测，以使终端在接收到该探测请 求消息后，能够对不同的天线路径进行测量，以获得不同的天线路径对应的信道质量。并且，路由器可以是以相同的发射功率，在多个不同的天线路径中同时发送该探测请求消息，以使对于多个不同的天线路径的探测更准确。终端将至少两个天线路径中各天线路径对应的信道质量反馈给路由器，使路由器可以明确各个天线路径的传输情况，例如，信道衰减情况等，方便后续对天线路径进行不同的处理。
在一实施例中，在执行步骤S101中的依据获取到的至少两个天线路径的信道质量，确定至少两个天线路径中各天线路径对应的传输参数之前，还包括：获取多个天线路径的信道质量；依据预设信道质量阈值和多个天线路径的信道质量，从多个天线路径中选择至少两个天线路径作为待使用传输路径。
其中，待使用传输路径用于传输通信信号。
例如，可以从多个天线路径中选择，信道质量大于或等于预设信道质量阈值的至少两个天线路径，作为待使用传输路径，从而剔除信道质量不同的天线路径，使用至少两个信道质量优异的天线路径作为待使用传输路径，对通信信号进行传输，能够使通信资源得到更优的配置，提升通信质量。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
下面结合附图，详细介绍根据本申请实施例的通信信号的传输装置。图3示出本申请实施例提供的通信信号的传输装置的组成方框图。如图3所示。该通信信号的传输装置包括但不限于如下模块。
确定模块301，被配置为依据获取到的至少两个天线路径的信道质量，确定至少两个天线路径中各天线路径对应的传输参数。
传输模块302，被配置为依据至少两个天线路径中各天线路径对应的传输参数，在至少两个天线路径上向终端传输通信信号。
在一实施例中，通信信号的传输装置应用于路由器。
在本实施例中，通过获取至少两个天线路径的信道质量，实现对至少两个天线路径的信道质量的监控，能够快速对不同的天线路径采取不同的调整方式，以适应不同的传输路径(如，折射路径和/或反射路径等)的传输要求；确定模块依据获取到的至少两个天线路径的信道质量，确定至少两个天线路径中各天线路径对应的传输参数，能够使各天线路径对应的传输参数更符合通信信号的传输需求，从而提升通信信号的传输质量；传输模块依据天线路径对应的传输参数，在至少两个天线路径上向终端传输通信信号，能够减少因电磁波的波长很短，所带来的信号衰落的问题，动态的调整各个天线路径的传输参数，提升通信设备之间通信效率。
本实施方式中所涉及到的各模块均为逻辑模块，在实际应用中，一个逻辑单元可以是一个物理单元，也可以是一个物理单元的一部分，还可以以多个物理单元的组合实现。此外，为了突出本申请实施例的创新部分，本实施方式中并没有将与解决本申请实施例所提出的技术问题关系不太密切的单元引入，但这并不表明本实施方式中不存在其它的单元。
图4示出本申请实施例提供的通信信号的传输系统的组成方框图。如图4所示。该通信 信号的传输系统包括但不限于如下设备。
路由器410和多个处于不同地理位置上的移动终端(如，第一移动终端421、第二移动终端422等)。其中，路由器410包括N根天线，N为大于或等于2的整数。例如，图4中示出了其中的四根天线，如，第一天线411、第二天线412、第三天线413和第四天线414。
路由器410可以通过多根天线与第一移动终端421建立多条天线路径，如，路由器410通过第一天线411与第一移动终端421之间建立天线路径1，路由器410通过第二天线412与第一移动终端421之间建立天线路径2，路由器410通过第三天线413与第一移动终端421之间建立天线路径3，以及路由器410通过第四天线414与第一移动终端421之间建立天线路径4。
路由器410还可以通过多根天线与第二移动终端422建立多条天线路径；如，路由器410通过第一天线411与第二移动终端422之间建立天线路径5，路由器410通过第二天线412与第二移动终端422之间建立天线路径6，路由器410通过第三天线413与第二移动终端422之间建立天线路径7，以及路由器410通过第四天线414与第二移动终端422之间建立第四天线路径8。
在某一时刻，以固定发送功率分别在第一天线411、第二天线412、第三天线413和第四天线414上同时发送通信信号，或，使用第一天线411、第二天线412、第三天线413和第四天线414依次向终端发送通信信号，以使第一移动终端421和/或第二移动终端422能够根据不同天线路径中接收到的通信信号的信号强度，确定不同天线路径对应的信道质量；进而将不同天线路径对应的信道质量反馈给路由器410。当路由器410获得终端反馈的各个天线路径对应的信道质量时，可以通过对不同的天线的发射功率、数据容量等传输参数进行调整，使不同的天线路径对应的传输参数更符合通信信号的传输需求；路由器410通过使用信道质量较优的至少两个天线路径进行通信信号的传输，能够提升通信信号的传输质量。
例如，对信道质量超过预设信道质量阈值的天线路径，可采用提高发射功率和/或增加数据容量的方式，对该天线路径进行调整；而对于信道质量小于预设信道质量阈值的天线路径，可采用减少发射功率和/或降低数据容量的方式，对该天线路径进行调整。
在第一移动终端421和/或第二移动终端422发生位置变更的情况下，其接收到的通过不同天线路径传输到不同终端的信号质量也会发生变化，此时，路由器410会获取第一移动终端421和/或第二移动终端422反馈的位置更新信息，其中，位置更新信息包括：第一移动终端421和/或第二移动终端422在更新后的位置上的、至少两个天线路径的信道质量；依据该位置更新信息，更新至少两个天线路径中各天线路径对应的传输参数，从而使信道质量较优的天线路径(如，信道质量超过预设信道质量阈值的天线路径)能够更有利于通信信号的传输；而在信道质量较差的天线路径(如，信道质量远小于预设信道质量阈值的天线路径)上，减少其传输的通信信号。
通过动态的对多个天线路径的信道质量进行监控，以使可以动态调整各个天线路径对应的传输参数(如，通信信号中的数据符号对应的调制编码比特的数量、所述天线路径对应的发射功率和所述至少两个天线路径对应的传输带宽中的至少一种)，能够使路由器与不同的移动终端之间进行动态的匹配，提升通信设备之间通信效率。
图5示出本申请实施例提供的通信信号的传输系统的工作方法的流程示意图。如图5所示。该通信信号的传输系统的工作方法包括但不限于如下步骤。
步骤S501，第一移动终端421在通过不同的天线路径接收路由器410发送的通信信号时，对不同的天线路径进行测量，获得不同的天线路径对应的信道质量，并将该信道质量反馈给路由器410。
其中，路由器410先分别与第一移动终端421和/或第二移动终端422建立通信连接，然后该路由器410的射频芯片会将需要传输的通信信号调制为无线电信号波形，通过功率放大器(Power Amplifier，PA)将调制后的通信信号进行放大，获得处理后的通信信号；再使用天线谐振向不同的移动终端发送该处理后的通信信号。
因路由器410具有N个天线，则对应的有N个天线路径，每个天线路径对应的发射功率、传输带宽、以及对其传输的通信信号中的数据符号对应的调制编码比特的数量等传输参数均不同。
例如，初始化阶段，每个天线路径对应的传输带宽为Y MHz，发射功率为X dBm，并采用对每个数据符号编入Z个比特的方式进行调制，从而为后续对天线路径的传输参数的调整提供基础参数。其中，X和Y均为实数，Z为大于或等于1的整数。
并且，在初始进行通信信号的发送时，因不确定每个天线路径对应的信道衰减情况，路由器410采用多个天线路径同时传输通信信号，以方便对不同的天线路径对应的传输环境进行探测，即，初始时，路由器采用的传输带宽为Y MHz，发射功率为X dBm，并采用对每个数据符号编入Z个比特的方式进行调制的方式，同时在多个天线路径中传输通信信号。
在一实施例中，路由器410还可用采用发送探测请求消息的方式，来获取不同的天线路径对应的信道质量。例如，路由器410使用至少两个天线路径向第一移动终端421和/或第二移动终端422发送探测请求消息；响应于第一移动终端421和/或第二移动终端422发送的探测响应消息，获取至少两个天线路径中各天线路径对应的信道质量。可根据该信道质量，明确不同的天线路径需要进行对应的不同的调整方式，以适应不同的传输路径的传输要求。
其中，信道质量包括：SINR、RSRP和接收信号的强度指标(Received Signal Strength Indicator，RSSI)中的至少一种。
例如，路由器410使用至少两个天线路径同时向第一移动终端421和/或第二移动终端422发送探测请求消息；路由器410也可以使用至少两个天线路径依次向第一移动终端421和/或第二移动终端422发送探测请求消息，以使第一移动终端421和/或第二移动终端422可以尽快获得该探测请求消息，并做出对应的响应，提升通信效率。
步骤S502，路由器410根据信道质量判断是否需要对不同的天线路径的传输参数进行调整。
在确定需要对不同的天线路径的传输参数进行调整的情况下，执行步骤S503；否则，在确定不需要对不同的天线路径的传输参数进行调整的情况下，继续执行步骤S501。
步骤S503，路由器410分别对至少两个天线路径对应的传输参数进行调整，生成至少两个天线路径中各天线路径对应的目标传输参数。
在一实施例中，路由器410依据至少两个天线路径的信道质量和预设信道质量阈值，确定至少两个天线路径中各天线路径对应的通信等级；依据至少两个天线路径中各天线路径的通信等级，确定至少两个天线路径中各天线路径对应的传输参数。
其中，传输参数包括：通信信号中的数据符号对应的调制编码比特的数量、天线路径对应的发射功率和至少两个天线路径对应的传输带宽中的至少一种。
例如，可以根据不同的阈值范围，定义天线路径对应的不同的通信等级。如，第一等级(如，具有1格的通信信号强度，即最差的通信质量)；第二等级(如，具有2格的通信信号强度)；第三等级(如，具有3格的通信信号强度)；第四等级(如，具有满格(4格)的通信信号强度，即最优的通信质量)。
例如，当RSPR在一定的较强的信号强度时，信号强度定义为4格；当RSPR在一定的普通的信号强度时，信号强度定义为3格；RSPR在较弱的信号强度时，信号强度定义为2格；RSPR在非常弱的信号强度时，强度定义为1格。
通过不同的通信等级能够表征天线路径对应的通信质量，进而根据不同的通信等级，对至少两个天线路径中各天线路径对应的传输参数进行调整，生成至少两个天线路径中各天线路径对应的目标传输参数。能够多维度的对天线路径进行调整，使各天线路径对应的传输参数更符合通信信号的传输需求，从而提升通信信号的传输质量。
其中，目标传输参数可以包括：调整后的调制编码比特的数量K、调整后的发射功率P和调整后的传输带宽M中的至少一种。
在一实施例中，调整后的调制编码比特的数量K可以采用如下公式(1)表示：
K＝2(n-1)*Z        (1)
其中，n表示通信等级，n为大于1的整数，Z表示预设调制编码比特的数量。
调整后的发射功率P可以采用如下公式(2)表示：
P＝X+3*(n-1)       (2)
其中，X表示预设发射功率阈值。
调整后的传输带宽M可以采用如下公式(3)表示：
M＝2(n-1)*Y         (3)
其中，Y表示预设传输带宽阈值。
例如，若某个天线路径(如，天线路径1)对应的通信等级为第一等级，则根据上述公式(1)～(3)的计算，可确定天线路径1对应的调整后的调制编码比特的数量K为Z个；调整后的发射功率P为X dBm；调整后的传输带宽M为Y MHz.。
若某个天线路径(如，天线路径2)对应的通信等级为第二等级，则根据上述公式(1)～(3)的计算，可确定天线路径2对应的调整后的调制编码比特的数量K为2Z个；调整后的发射功率P为(X+3)dBm；调整后的传输带宽M为2YMHz。
若某个天线路径(如，天线路径3)对应的通信等级为第三等级，则根据上述公式(1)～(3)的计算，可确定天线路径3对应的调整后的调制编码比特的数量K为4Z个；调整后的发射功率P为(X+6)dBm；调整后的传输带宽M为4YMHz。
若某个天线路径(如，天线路径4)对应的通信等级为第四等级，则根据上述公式(1)～(3)的计算，可确定天线路径4对应的调整后的调制编码比特的数量K为8Z个；调整后的发射功率P为(X+9)dBm；调整后的传输带宽M为8YMHz。
类似的，天线路径5～天线路径8也可以根据上述公式(1)～(3)计算获得其对应的传输参数。
在一实施例中，还可以从多个天线路径中选择至少两个天线路径作为待使用传输路径，例如，待使用传输路径对应的通信等级大于或等于预设等级阈值(如，预设等级阈值为1或2等)，或，待使用传输路径对应的信道质量超过预设信道质量阈值；该待使用传输路径用于 传输通信信号，以使可以采用信道质量最优的天线路径来传输通信信号，提升通信信号的传输效率。
预设信道质量阈值可以是预设传输带宽阈值(M、2M等)，也可以是预设发射功率阈值(X dBm、(X+3)dBm等)，还可以是预设调制编码比特的数量阈值(Z个、2Z个等)；以上对于预设信道质量阈值仅是举例说明，可以根据实际需要进行具体设定或组合，其他未说明的预设信道质量阈值也在本申请的保护范围之内，在此不再赘述。
步骤S504，路由器410依据至少两个天线路径中各天线路径对应的目标传输参数，在至少两个天线路径上向第一移动终端421传输通信信号。
通过在至少两个天线路径上同时向第一移动终端421传输通信信号，或，使用至少两个天线路径依次向第一移动终端421传输通信信号，能够减少因电磁波的波长很短，所带来的信号衰落的问题，动态的调整各个天线路径的传输参数，提升通信设备之间通信效率。
在一实施例中，路由器410还可以根据移动终端所在的实时位置对不同的天线路径对应的传输参数进行更新。例如，路由器410获取第一移动终端421反馈的位置更新信息，其中，位置更新信息包括：第一移动终端421在更新后的位置上的、至少两个天线路径的信道质量；依据位置更新信息，更新至少两个天线路径中各天线路径对应的传输参数。
能够使信道质量好的天线路径(如，信道质量超过预设信道质量阈值的天线路径)可以有更高的发射功率、更宽的传输带宽，以及更高的调制编码比特的数量等，提升通信信号的传输质量。还能够使信道质量差的天线路径(如，信道质量小于预设信道质量阈值的天线路径)采用减少发射功率、降低传输带宽和降低调制编码比特的数量中的至少一种的调整方式，来对该信道质量差的天线路径对应的传输参数进行调整，使该信道质量差的天线路径不占用过多的通信资源，提升通信资源的利用效率。
在执行完步骤S504之后，还可以继续返回执行步骤S501，以使路由器410可以动态监控每个天线路径对应的信道质量，从而对各个天线路径的传输参数进行动态调整，提升通信效率。
在本实施例中，通过动态的监控多个天线路径中个天线路径对应的信道质量，动态调整每个天线路径的发射功率、传输带宽和调制编码比特的数量等传输参数，使调整后的天线路径对应的传输参数更符合通信信号的传输需求，从而提升通信信号的传输质量；在第一移动终端421和/或第二移动终端422的实时位置发送变化的情况下，能够更新至少两个天线路径中各天线路径对应的传输参数，使路由器和不同的移动终端之间能够动态匹配，提升移动终端的业务处理效率。
