Description

一种无线通信系统中的通信方法和通信装置
本申请要求于2020年05月08日提交中国专利局、申请号为202010381950.9、申请名称为“一种无线通信系统中的通信方法和通信装置”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
本申请涉及无线通信领域，尤其涉及一种无线通信系统中的通信方法和通信装置。
背景技术
随着无线通信技术的不断发展，具有短距无线传输能力的产品越来越丰富，并且这些产品的用户数量也在不断的增长。当前，这些产品中的大多数都是采用蓝牙技术或者蓝牙衍生技术进行信息传输。而由于蓝牙技术与WiFi技术或者Zigbee技术共享频谱，这就导致了无线通信干扰的出现。为了减少这类干扰，人们提出了一种跳频技术。所谓的跳频技术，就是两个进行短距离无线通信的设备(后文假设为主设备和从设备)在通信过程所采用的载波频率在一定范围内按照某个规律跳变(也就是说，所使用的无线信道会规律性的改变)。具体实现中，主设备和从设备之间会使用一个跳频地图(这个跳频地图通常由主设备设计得到)，这个跳频地图指示了当前情况下主设备与从设备之间的所有工作信道中的至少一个可用信道。主设备和从设备在某段时间内会随机的从这些可用信道中选择出一个可用信道来进行通信。实际应用中，主设备通常是依靠其自身获取的信道质量评估结果以及从设备上报的信道质量评估结果来设计跳频地图。然而，在现有技术中，从设备上报的信道质量评估结果无法准确的指示出主设备与从设备之间的信道的信道质量的好坏程度，并且信道质量评估结果的上报形式也较为单一，从而导致信道质量上报的灵活度较差。
发明内容
为了解决上述问题，本申请提供了一种无线通信系统中的通信方法和通信装置，可适应性地以不同的精度上报信道质量，提升了信道质量上报的灵活度。
第一方面，本申请实施例提供了一种无线通信系统中的通信方法。包括：第一终端设备接收第二终端设备发送的第一信道质量上报信息。这里，该第一信道质量上报信息的格式为预设的至少两种格式中的一种。该第一信道质量上报信息中包括由第二终端设备确定的至少一个目标信道的信道质量参量。上述至少一个目标信道为第一终端设备与第二终端设备之间的无线信道。任一目标信道对应的信道质量参量可用于指示该目标信道的信道质量的好坏程度。第一终端设备对第一信道质量上报信息进行解析，以获取至少一个目标信道的信道质量参量。
在本申请实施例中，第一终端设备接收到第二终端设备适应性的以不同格式上报的第一信道质量上报信息，从而可获取到精度合适的各目标信道的信道质量参量，提升了信道质量上报的有效性。
结合第一方面，在一种可能的实施方式中，第一终端设备可根据上述至少一个目标信道的信道质量参量更新第一跳频地图。其中，该第一跳频地图可用于第一终端设备确定其与第二终端设备之间的至少一个可用信道。第一终端设备根据精度合适的至少一个目标信道的信 道质量参量对第一跳频地图进行更新，以得到更加准确的第一跳频地图，可提升跳频技术的抗干扰能力。
结合第一方面，在一种可能的实施方式中，第一终端设备可向第二终端设备发送信道质量评估请求。这里，该信道质量评估请求中可包括上报模式指示信息，该上报模式指示信息可用于指示第二终端设备发送的第一信道质量上报信息的格式。该信道质量评估请求可用于请求第二终端设备上报特定格式的第一信道质量上报信息。第一终端设备可通过信道质量上报请求来及时的触发第二终端设备上报第一信道质量上报信息，保证了第一信道质量上报信息的时效性。进一步的，也能使得第一终端设备能够及时的基于第一信道质量上报信息来更新第一跳频地图，可提升第一跳频地图的时效性和准确性。
结合第一方面，在一种可能的实施方式中，信道质量评估请求中还包括有第一时间间隔和第二时间间隔，所述第二时间间隔大于所述第一时间间隔。上述上报模式指示信息还可用于指示第二终端设备在第一时间间隔内发送第一信道质量上报信息；或者，上述上报模式指示信息还可用于指示第二终端设备在第二时间间隔内发送第一信道质量上报信息；或者，上述上报模式指示信息还可用于指示第二终端设备在第二时间间隔内以第一时间间隔为发送间隔来发送第一信道质量上报信息。
结合第一方面，在一种可能的实现方式中，信道质量评估请求中还包括有目标时刻。上述上报模式指示信息还可用于指示第二终端设备在目标时刻上或者目标时刻之前发送第一信道质量上报信息。

结合第二方面，在一种可能的实施方式中，第二终端设备可接收第一终端设备发送的更新后的第一跳频地图。然后，第二终端设备可根据所述更新后的第一跳频地图来更新第二跳频地图。
第三方面，本申请实施例提供了一种无线通信系统中的通信装置，该通信装置可以为第一终端设备或者第一该终端设备中的芯片，比如蓝牙芯片。包括：
收发单元，用于接收来自于第二终端设备的第一信道质量上报信息。这里，所述第一信道质量上报信息的格式为预设的至少两种格式中的一种，所述第一信道质量上报信息中包括由所述第二终端设备确定的至少一个目标信道的信道质量参量，所述目标信道为所述第二终端设备与所述第一终端设备之间的无线信道；

上述任一方面的一种可能的实施方式中，所述信道质量评估请求还包括：目标信道指示信息，所述目标信道指示信息用于指示所述至少一个目标信道。也就是说第一终端设备可指定第二终端设备对其需要的至少一个目标信道进行信道质量参量的确定和上报，一方面能够使得第二终端设备无需对所有的信道进行信道质量参量的确定，节省第二终端设备的数据处理量。另一方面也能使得后续第一终端设备无需对除目标信道以外的其他信道进行信道质量参量的提取，也能节省第一终端设备的数据处理量。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
本申请实施例提供了一种通信方法，该方法适用于各种通过结合有跳频技术(如自适应跳频技术(adaptive frequency hopping，AFH))的短距离无线通信技术进行无线通信的通信系统。这里，上述短距离无线通信技术包括但不限于蓝牙(Bluetooth)技术、无线上网(wireless fidelity，WiFi)技术、紫蜂(即Zigbee)技术、802.15.4协议等。
本申请实施例中涉及的第一终端设备或者第二终端设备即可以是用户设备、移动设备、用户终端、终端、短距离无线通信设备，也可以是具有短距离无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、可穿戴设备等，本申请实施例对此并不限定。为方便理解，在本申请实施例中，将以第一终端设备或者第二终端设备统一进行描述。
请参见图1，图1是本申请实施例提供的一种通信系统的结构示意图。由图1可知，该通信系统中主要包括第一终端设备与第二终端设备。这里，该第一终端设备和第二终端设备基于蓝牙等短距离无线通信技术进行信息交互。在实际应用中，由于蓝牙技术、WiFi技术以及Zigbee技术均工作在ISM 2.4Ghz频段，这就会导致在同一环境下同时使用这些短距离无线通信技术的设备之间存在强烈的信号干扰。例如，假设在第一终端设备和第二终端设备之间通过蓝牙进行数据传输的同时，第一终端设备还与第三终端设备通过WiFi进行数据传输，当第一终端设备和第二终端设备之间所使用的信道的频率和第一终端设备与第三终端设备之间所使用的信道的频率相同或者相近时，这极容易导致第一终端设备与第二终端设备和第三终端设备之间的通信互相产生干扰，从而降低了第一终端设备与第二终端设备和第三终端设备之间的通信质量。为了解决这一问题，人们提出跳频技术。所谓的跳频技术，就是两个进行短距离无线通信的设备(如第一终端设备和第二终端设备)在通信过程所采用的载波频率 在一定范围内按照某个规律跳变(也就是说，所使用的无线信道会规律性的改变)。具体实现中，第一终端设备和第二终端设备之间会使用一个跳频地图，这个跳频地图指示了当前情况下第一终端设备与第二终端设备之间的一个或者多个信道质量较好的可用信道。第一终端设备和第二终端设备在某段时间内会随机的从这些可用信道中选择出一个可用信道来进行通信。通过跳频地图的使用，可以使得第一终端设备和第二终端设备避免使用其他设备已经占用的信道进行通信所导致的通信质量差的问题。由于跳频地图直接指示了可用信道，因此，决定上述跳频技术的抗干扰性能的重要因素之一是跳频地图的准确度。
需要说明的是，一般情况下，设计跳频地图的设备可称为主设备，使用跳频地图的另一方可称为从设备。在本申请中，第一终端设备为主设备，第二终端设备为从设备。第一终端设备通常可对其与第二终端设备之间的信道的进行信道评估以得到一个信道质量评估结果(这里假设为第一信道质量评估结果)。第二终端设备也会对上述信道进行评估以得到一个信道质量评估结果(这里假设为第二信道质量评估结果)并上报给第一终端设备。然后第一终端设备即可根据上述第一信道质量评估结果和第二信道质量评估结果来设计一个新的跳频地图以供第一终端设备和第二终端设备使用。但是，在当前技术下，第二终端设备上报的第二信道质量评估结果无法准确且详细的指示出信道的信道质量的好坏程度(例如，第二终端设备上报的信道质量评估结果中每个信道的评估结果只有好与坏之分)，并且上报信道质量评估结果的形式也较为单一，从而导致信道质量上报灵活度低。
因此，本申请实施例的方法采用不同的格式，以不同的精度上报信道质量信息，可提升信道质量上报的灵活度。进一步的，上报的信道质量信息可供第一终端设备更新跳频地图，从而可提升第一终端设备所设计的跳频地图的准确性，以提升跳频技术的抗干扰能力。
下面，为了方便对本申请实施例的理解和描述，首先对本申请实施例涉及的到的相关概念进行描述。
1、跳频地图
实际应用中，跳频地图指示了两个终端设备之间的多个信道中哪些信道为可用信道，哪些信道为不可用信道。两个终端设备共用同一个跳频地图。请参见图2，图2是本申请实施例提供的一种跳频地图示意图。需要说明的是，在本申请实施例中，假设第一终端设备和第二终端设备之间存在N1个信道。这里，N1为正整数。每个信道对应有一个信道标识，后文将以信道的编号作为每个信道的信道标识来描述。如N1个信道中可包括标识为信道0、信道1、信道2的多个信道。请参见图2，图2是本申请实施例提供的一种跳频地图示意图。如图2所示，跳频地图中包括有N1个信道中各信道的信道标识以及各信道对应的可用性指示标识。在本申请中，假设可用性指示标识有两种取值，包括0和1。若该可用性指示标识为0，则指示对应的信道为不可用信道。若该可用性指示标识取值为1，则指示对应的信道为可用信道。如图2所示，该跳频地图指示了信道0、信道2和信道N1-1为可用信道，信道1和信道N1-2为不可用信道。
请参见图3a，图3a是本申请实施例提供的一种通信方法一流程示意图。由图3a可知，本申请实施例提供的通信方法包括但不限于以下步骤：
S101，第二终端设备确定第一信道质量指示信息。
S102，第二终端设备向第一终端设备发送第一信道质量上报信息。
S103，第一终端设备接收第一信道质量上报信息并解析得到至少一个目标信道的信道质量参量。
可选的，S104，第一终端设备根据所述至少一个目标信道的信道质量参量更新第一跳频 地图。这里可以理解的是，第一终端设备还可以利用至少一个目标信道的信道质量参量作其他用途，本申请不做具体限制。
在一些可行的实现方式中，在第二终端设备确定需要向第一终端设备进行信道质量的上报后，第二终端设备可获取到上述N1个信道中的一个或者多个信道(为方便理解和区别，下文将以N2个目标信道代替描述，N2为大于或者等于1的整数)。
本申请实施例提供了至少四种第一信道质量上报信息的格式，下面将分别对每种格式下的第一信道质量上报信息进行简单的描述。
格式一：
格式一下的第一信道质量上报信息中包含有第一终端设备与第二终端设备之间的所有信道的信道质量参量(即目标信道的个数N2等于N1)。这里，信道质量参量至少对应有三个量化值，分别为第一量化值、第二量化值和第三量化值。其中，第一量化值的信道质量参量用于指示对应信道的信道质量为未知。第二量化值的信道质量参量用于指示对应信道的信道质量为好，第三量化值的信道质量参量用于指示对应信道的信道质量为差。在这N1个目标信道中，信道2n和信道2n+1共用同一个信道质量参量。这里，n为大于或者等于0且小于或者等于(N1-1)/2的正整数。概括的来说，就是格式一下的第一信道质量上报信息中包含有n+1个信道质量参量，指示了上述N1个目标信道中每个目标信道的信道质量为好或者差。
格式二：
格式二下的第一信道质量上报信息中也包含有第一终端设备与第二终端设备之间的所有信道的信道质量参量。这里，信道质量参量仅对应有两个量化值，分别为第一量化值和第二量化值。其中，第一量化值的信道质量参量用于指示对应信道的信道质量为好，第二量化值的信道质量参量用于指示对应信道的信道质量为差。在格式二下的第一信道质量上报信息中，一个目标信道对应有一个信道质量参量。即第n个信道质量参量仅用于指示信道n的信道质量。这里，n为大于或者等于0且小于或者等于N1-1的正整数。概括的来说，就是格式二下的第一信道质量上报信息中包含有N1个信道质量参量，指示了上述N1个目标信道中每个目标信道的信道质量为好或者差。
格式三：
格式三下的第一信道质量上报信息中包含有第一终端设备与第二终端设备之间的部分信道的信道质量参量(即N2小于N1)。这里，信道质量参量对应有四个量化值，分别为第一量化值、第二量化值、第三量化值和第四量化值。其中，第一量化值的信道质量参量用于指示对应信道的信道质量为未知。第二量化值的信道质量参量用于指示对应信道的信道质量为好，第三量化值的信道质量参量用于指示对应信道的信道质量为适用(或中等)，第四量化值的信道质量参量用于指示对应信道的信道质量为差。在这N2个目标信道中，一个目标信道对应一个信道质量参量。即第n个信道质量参量仅用于指示信道n的信道质量。这里，n为大于或者等于0且小于或者等于N2-1的正整数。概括的说，就是格式三下的第一信道质量上报信息中包含有N2个目标信道对应的N2个信道质量参量，指示了上述N2个目标信道的信道质量为好、适用或者差。
格式四：
格式四下的第一信道质量上报信息中包含有第一终端设备与第二终端设备之间的部分信道的信道质量参量(即N2小于N1)。在该格式下，信道质量参量对应有五个或者更多个量化值，不同量化值的信道质量参量指示了对应信道的信道质量好坏的不同程度。在格式四下的第一信道质量上报信息中，一个目标信道对应一个信道质量参量。即第n个信道质量参量 仅用于指示信道n的信道质量。这里，n为大于或者等于0且小于或者等于N2-1的正整数。概括的说，就是格式四下的第一信道质量上报信息中包含有N2个信道质量参量，每个信道质量参量能够从五个或者更多个层次来指示出某个目标信道的信道质量的好坏程度。
这里需要说明的是，如同上述四种格式所示，在考虑第一信道质量上报信息中所指示的目标信道的个数或者每个目标信道的信道质量参量的量化精度不同的情况下，本申请实施例还可以扩展出更多种第一信道质量上报信息的格式，此处便不再一一赘述。
下面将结合蓝牙(basic rate/enhanced data rate，BR/EDR)版本对上述四种格式的第一信道质量上报信息的具体实现作进一步的描述。实际应用中，蓝牙BR/EDR版本中规定了第一终端设备和第二终端设备之间存在79个信道。

Figure PCTCN2021092368-appb-000001
请参见表1-1，表1-1是本申请实施例提供的第一信道质量上报信息的格式对照表。如表1-1中所示，格式一下的第一信道质量指示信息的字段长度为10字节。其具体可以是一个包含有40个元素(即0号到39号元素)的整型数组。其中，一个元素对应一个信道质量参量，第n个信道质量参量指示了信道2n和信道2n+1的信道质量，第39个信道质量参量指示了信道79的信道质量。这里，每个信道质量参量占用2个比特，可以有0、1、2和3这四种取值。例如，0就是前文叙述的格式一下的第一量化值，1是第二量化值，3是第三量化值。这两个比特为2的取值可作为预留取值，供未来设计使用。当这两个比特取值为0时，该信道质量参量用于指示信道的信道质量为未知。当这两个比特取值为1时，该信道质量参量用于指示信道的信道质量为好。当这两个比特取值为3时，该信道质量参量用于指示信道的信道质量为差。
格式二下的第一信道质量指示信息的字段长度为10字节。其具体可以是一个包含有80个元素(即0号到79号元素)的整型数组。其中，一个元素对应一个信道质量参量，第n个信道质量参量指示了信道n的信道质量，第79号元素作为预留元素，供未来设计使用。这里，每个信道质量参量占用1个比特，共存在0和1这两种取值。例如，1就是前文叙述的格式二下的第一量化值，0是第二量化值。当这个比特取值为0时，该信道质量参量用于指示信道的信道质量为差。当这个比特取值为1时，该信道质量参量用于指示信道的信道质量为好。
格式三下的第一信道质量指示信息的字段长度为10字节。其具体可以是一个包含有40个元素(即0号到39号元素)的整型数组。对应指示了79个信道中的40个信道的信道质量。其中，一个元素对应一个信道质量参量，第n个信道质量参量指示了上述40个信道中第n个 信道的信道质量。这里，每个信道质量参量占用了2个比特，共存在包括0、1、2和3这四种取值。例如，0就是前文叙述的格式三下的第一量化值，1是第二量化值，3是第三量化值，4是第四量化值。当这2个比特取值为0时，该信道质量参量用于指示信道的信道质量为未知。当这2个比特取值为1时，该信道质量参量用于指示信道的信道质量为好。当这2个比特取值为2时，该信道质量参量用于指示信道的信道质量为适用。当这2个比特取值为3时，该信道质量参量用于指示信道的信道质量为差。
格式四下的第一信道质量指示信息的字段长度为10字节。其具体可以是一个包含有20个元素(即0号到19号元素)的整型数组。对应指示了79个信道中的20个信道的信道质量。其中，一个元素对应一个信道质量参量，第n个信道质量参量指示了上述20个信道中第n个信道的信道质量。这里，每个信道质量参量占用4个比特，共存在16种取值，对应了前文叙述的格式四下信道质量参量的16种量化值。例如，当这四个比特取值为0时，该信道质量参量用于指示信道的信道质量为未知。剩下15种取值(包括1到15)分别从15个层次指示了信道的信道质量的好坏。
可选的，具体实现中，第一信道质量上报信息可承载于蓝牙BR/EDR版本中所记载的CQI-res报文中。这里，承载有第一信道质量上报信息的CQI-res报文的报文长度可以为12字节或者13字节。当CQI_res报文有12个字节时，该CQI_res报文中的channel_quality_index字段可作为上述任一格式下的第一信道质量上报信息。当CQI_res报文有13个字节时，该CQI_res报文中的channel_quality_index字段可作为上述任一格式下的第一信道质量上报信息，该CQI_res报文中的CQI_req_format字段可用于指示第一信道质量上报信息格式的格式指示信息。该格式指示信息具体可以为第一格式标识、第二格式标识、第三格式标识或者第四格式标识，分别用于指示上述格式一、格式二、格式三或者格式四。
这里，第二终端设备可通过上述格式二、格式三或者格式四的第一信道质量上报信息为第一终端设备提供不同精度的信道质量参量，提升了信道质量上报的灵活度。
下面将结合上述四种格式以及第二终端设备主动上报第一信道质量上报信息或者第二终端设备根据第一终端设备的请求上报第一信道质量上报信息这两种场景，对第二终端设备生成第一信道质量上报信息的过程进行详细的描述。
场景一(第二终端设备主动上报第一信道质量上报信息)：
第二终端设备首先可对上述N1个信道中各个信道进行信道质量测量，以得到各个信道对应的信道质量测量值。具体实现中，第二终端设备可以执行全频段扫描，以得到上述各个信道的接收信号强度，并将各个信道的接收信号强度作为各个信道的信道质量测量值。此外，第二终端设备也可将各个信道的参考信号的接收功率、信干噪比等参量确定为各个信道的信道质量测量值，本申请不作具体限制。
在一种可选的实现中，第二终端设备可根据，其使用的第二跳频地图所指示的至少一个可用信道与至少一个第二信道，来确定其是否需要主动生成并向第一终端设备发送上述第一信道质量上报信息。这里，上述第二信道由第二终端设备根据各信道的信道质量测量值从N1个信道确定出来。上述第二跳频地图用于第二终端设备确定其与第一终端设备之间哪些信道可用，哪些信道不可用。在第一跳频地图没有更新的情况下，上述第一跳频地图和第二跳频地图相同。具体的，请参见图3b，图3b是本申请实施例提供的一种触发条件判断流程示意图。如图3b所示，A1，第二终端设备可根据第二跳频地图中各信道对应的可用性指示标识确定出第二跳频地图所指示的一个或者多个可用信道(这里假设为N3个，N3为正整数)。然后，第二终端设备也可从上述N1个信道中确定出N3个信道质量测量值等于或者大于第二 预设测量值的第二信道。这里需要说明的是，若N1个信道中信道质量测量值等于或者大于第二预设测量的信道的个数多于N3，则可随机剔除多余的信道。若N1个信道中信道质量测量值等于或者大于第二预设测量的信道的个数少于N3，则可从剩余不满足该条件的信道中随机挑选出多个信道作为第二信道，以使得第二信道的个数等于N3。或者，第二终端设备也可按照信道质量测量值的大小对上述N1个信道进行排序，并提取出排序靠前的N3个信道作为N3个第二信道。换一句话说，就是第二信道的信道质量测量值要大于上述N1个信道中除第二信道以外的信道的信道质量测量值。A2，第二终端设备可确定出上述N3个可用信道中，没有包含在上述N3个第二信道中的可用信道的个数(为了方便区别，下文将以第二个数代替描述)。A3，第二终端设备根据这第二个数来确定是否生成并向第一终端设备发送第一信道质量上报信息。例如，第二终端设备可判断上述第二个数是否等于或者大于第一预设个数。或者，第二终端设备可计算出第二个数与信道个数N3的比值(这里假设为D1)，并判断D1是否等于或者大于第一预设比值。A4，若第二终端设备确定第二个数等于或者大于第一预设个数，或者，确定D1等于或者大于第一预设比值，则其可确定生成并向第一终端设备发送第一信道质量上报信息。若第二终端设备确定上述第二个数小于第一预设个数或者D1小于第一预设比值时，则可确定本次无需生成第一信道质量上报信息，并重复执行A1的操作。例如，上述N3个可用信道中包括信道0、信道1、信道2和信道3。上述N3个第二信道中包括信道2、信道3、信道4和信道5。第二终端设备可确定N3个可用信道中有信道0和信道1这2个信道不包含于上述N3个第二信道中，即上述第二个数为2。然后，假设第一预设个数为1，则第二终端设备可确定第二个数要大于第一预设个数，从而可确定其需要生成并向第一终端设备发送第一信道质量上报信息。或者，假设第一预设比值为0.3。第二终端设备可以计算出第二个数与N3的比值D1＝1/2＝0.5。然后，第二终端设备确定D1大于第一预设比值，则可确定其需要生成并向第一终端设备发送第一信道质量上报信息。
在第二终端设备确定发送第一信道质量上报信息的情况下，第二终端设备可先根据N1个信道中各信道的信道质量测量值生成上述格式一、格式二、格式三或者格式四中任一格式的第一信道质量上报信息。这里需要说明的是，上述第一信道质量上报信息的格式(为了方便理解，下文将以目标格式代替描述)可以是第一终端设备和第二终端设备之间的通信协议中预定的，并且优选上述格式三或者格式四。具体实现中，第二终端设备可根据将要生成的第一信道质量上报信息的目标格式从上述N1个信道中选择出N2个目标信道。例如，若目标格式为格式一或者格式二，则上述N2个目标信道就是上述N1个信道。若目标格式为格式三或者格式，则上述N2个目标信道就是上述N1个信道中信道质量测量值排序靠前的N2个信道或者排序靠后的N2个信道。然后，第二终端设备可通过不同格式对应的不同的量化规则对上述N2个目标信道的信道质量测量值进行量化，以得到各目标信道的信道质量参量。这里需要说明的是，不同的量化规则对应的量化精度不同。或者说，不同格式下信道质量参量所对应的量化层次不同，量化层次越多，则信道质量参量的量化精度越高。例如，上述格式一和格式二所对应的信道质量参量的量化精度相同，只有3个量化层次，能指示信道的信道质量为好、坏或者未知。上述格式三对应的信道质量参量的量化精度要高于格式一和格式二，其量化值有四个层次，可指示信道的信道质量为好、适用、坏或者未知。上述格式四对应的信道质量参量的量化精度要高于格式一、格式二和格式三，其量化值有五个或者更多个层次，能够更加准确的指示出各信道的信道质量。其后，第二终端设备可基于各个目标信道的信道质量参量确定出目标格式下的第一信道质量上报信息。
下面将结合前文表1-1中所描述的四种格式的具体实现形式，对第二终端设备生成不同 格式的第一信道质量上报信息的过程进行描述。
在目标格式为格式一的情况下，第二终端设备设备可确定第一终端设备和第二终端设备之间的79个信道都是目标信道。然后，第二终端设备可采用格式一对应的量化规则(为方便理解，下文将以第一量化规则代替描述)逐个对上述79个目标信道的信道质量测量值进行量化处理，以得到上述79个目标信道的信道质量参量。这里，该第一量化规则具体可以是：信道质量测量值为0或者为空，则对应的信道质量参量为0。信道质量参量等于或者大于第一预设测量值，则对应的信道质量参量为1。信道质量参量大于0且小于第一预设测量值，则对应的信道质量参量为3。然后，第二终端设备可按照前文对格式一的描述将上述79个目标信道的信道质量参量承载在一个长度为10字节且包含有40个元素(即元素0到元素39)的整型数组中，以得到格式一下的第一信道质量上报信息。
在目标格式为格式二的情况下，第二终端设备设备也可确定第一终端设备和第二终端设备之间的79个信道都是目标信道。然后，第二终端设备可采用格式二对应的量化规则(为方便理解，下文将以第二量化规则代替描述)逐个对上述79个目标信道的信道质量测量值进行量化处理，以得到上述79个目标信道的信道质量参量。这里，该第二量化规则具体可以是：信道质量参量等于或者大于第一预设测量值，则对应的信道质量参量为1。信道质量参量小于第一预设测量值，则对应的信道质量参量为0。然后，第二终端设备可按照前文对格式二的描述将上述79个目标信道的信道质量参量承载在一个长度为10字节包含有80个元素(即元素0到元素79)的整型数组中，以得到格式二下的第一信道质量上报信息。
在目标格式为格式三的情况下，第二终端设备可选择40个信道作为目标信道，例如，第二终端设备可先按照信道质量测量值的大小对上述79个信道进行排序，然后选择排序靠前或者排序靠后的40个信道作为目标信道。然后，第二终端设备可采用格式三对应的量化规则(为方便理解，下文将以第三量化规则代替描述)逐个对上述40个目标信道的信道质量测量值进行量化处理，以得到上述40个目标信道的信道质量参量。这里，该第三量化规则具体可以是：信道质量测量值为0或者为空，则对应的信道质量参量为0。信道质量参量等于或者大于第一预设测量值，则对应的信道质量参量为1。信道质量参量大于第二预设测量值且小于第一预设测量值，则对应的信道质量参量为2。信道质量参量大于0且小于或者等于第二预设测量值，则对应的信道质量参量为3。然后，第二终端设备可按照前文对格式三的描述将上述40个目标信道的信道质量参量承载于一个长度为10字节包含有40个元素的整型数组中，以得到格式三下的第一信道质量上报信息。当然，若第二终端设备不需要上报40个目标信道的信道质量，那么在采用格式三上报时，部分元素的取值可以为空或者为零。
在目标格式为格式四的情况下，第二终端设备可选择20个信道作为目标信道。例如，第二终端设备可采用上述格式三所描述的方式从79个信道中确定出20个目标信道。然后，第二终端设备可采用格式四对应的量化规则(为方便理解，下文将以第四量化规则代替描述)逐个对上述20个目标信道的信道质量测量值进行量化处理，以得到上述40个目标信道的信道质量参量。这里，该第四量化规则具体可以是：信道质量测量值为0或者为空，则对应的信道质量参量为0。信道质量测量值等于或者大于第一预设测量值，则对应的信道质量参量为1。信道质量测量值等于或者大于第二预设测量值且小于第一预设测量值，则对应的信道质量参量为2。信道质量测量值等于或者大于第三预设测量值且小于第二预设测量值，则对应的信道质量参量为3。以此类推，第四量化规则共指示了16个测量值区间与16个信道质量参量的量化值之间的对应关系。然后，第二终端设备可按照前文对格式四的描述将上述20个目标信道的信道质量参量承载于一个长度为10字节包含有20个元素(即元素0到元素19) 的整型数组中，以得到格式四下的第一信道质量上报信息。这里，该整型数组中的每个元素对应承载了一个信道质量参量。当然，若第二终端设备不需要上报20个目标信道的信道质量，那么在采用格式四上报时，部分元素的取值可以为空或者为零。
在另一种可选的实现中，第二终端设备可根据，第二跳频地图所指示的至少一个可用信道(这里假设为N3)与其根据各信道的信道质量参量从N1个信道的确定出的至少一个第二信道，来确定其是否需要主动生成并向第一终端设备发送第一信道质量上报信息。具体实现中，第二终端设备可根据第二跳频地图中各信道的可用性指示标识确定出上述N3个可用信道。其后，第二终端设备在获取到上述N1个信道中各信道的信道质量测量值之后，可通过上述第一量化规则、第二量化规则、第三量化规则或者第四量化规则中的任意一种对各信道的信道质量测量值进行量化处理，以得到各信道的信道质量参量。具体量化过程可参见前文叙述的量化过程此处便不再赘述。然后，第二终端设备可根据各信道的信道质量参量从上述N1个信道中确定出N3个第二信道。可选的，第二终端设备可将上述N1个信道中信道质量参量等于第一预设参量的信道作为第二信道。例如，在通过上述第一量化规则进行量化的情况下，第二终端设备可将上述N1个信道中信道质量参量等于1的信道确定为第二信道。在通过上述第三量化规则进行量化的情况下，第二终端设备可将上述N1个信道中信道质量参量或者等于2的信道确定为第二信道。或者，第二终端设备也可按照信道质量参量的大小对上述N1个信道进行排序，并提取出排序靠后的N3个信道作为第二信道。然后，第二终端设备即可根据第二跳频地图所指示的N2个可用信道和上述N2个第二信道确定是否主动向第一终端设备发送第一信道质量上报信道，并在确定需要主动生成并发送第一信道质量上报信息的情况下，生成目标格式下的第一信道质量上报信息。这里，第二终端设备确定是否生成并发送目标格式下的第一信道质量上报信息的过程可一并参见前文叙述的第二终端设备确定是否生成并发送目标格式下的第一信道质量上报信息的过程，此处便不再赘述。
这里，第二终端设备，基于其当前的第二跳频地图所指示的至少一个可用信道以及其通过信道质量估计确定的信道质量较好的至少一个第二信道之间的差异大小，来判定是否主动向第一终端设备发送第一信道质量上报信息，方法简单，易于实现。并且，第二终端设备在发现上述至少一个可用信道和至少一个第二信道存在较大差异的情况下(即发现第二跳频地图不准确的情况下)主动的向第一终端设备发送第一信道质量上报信息，可提升信道质量上报的有效性。进一步的，第二终端设备也能通过第一信道质量上报信息及时的触发第一终端设备后续对第一跳频地图进行调整，可保证第一跳频地图和第二跳频地图的准确性，提升跳频技术的抗干扰能力。
场景二(第二终端设备基于第一终端设备的请求上报第一信道质量上报信息)：
请一并参见图4，图4是本申请实施例提供的一种通信方法又一流程示意图。由图4可知，在第二终端设备基于第一终端设备的请求上报第一信道质量上报信息的场景下，在上述步骤S101之前，本申请实施提供的通信方法还包括以下步骤：
S1011，第一终端设备生成信道质量评估请求。
S1012，第一终端设备向第二终端设备发送信道质量评估请求。
S1013，第二终端设备接收来自于第一终端设备的信道质量评估请求。
在一些可行的实现方式中，若第一终端设备确定需要主动请求第二终端设备上报第一信道质量上报信息，则可生成一个信道质量评估请求。这里，该信道质量评估请求可包括上报模式指示信息。该上报模式指示信息可用于指示第二设备发送的第一信道质量上报信息的格式(同场景一中所描述的目标格式，后文将继续以目标格式代替描述)。这里，该目标格式可 以是上述格式一到格式四中的任意一种。
进一步，在一种可选的实现中，上述信道质量评估请求还可包括第一时间间隔和第二时间间隔。这里，上述第一时间间隔和第二时间间隔可以是第一终端设备经过多次通信实验得到的经验值。上述上报模式指示信息还可用于指示第二终端设备如何基于上述第一时间间隔和/或第二时间间隔来发送第一信道质量上报信息。具体的，上报模式指示信息还可用于指示第二终端设备在上述第一时间间隔内向第一终端设备发送一次或者多次第一信道质量上报信息。或者，上报模式指示信息还可用于指示第二终端设备在上述第二时间间隔内向第一终端设备发送一次或者多次第一信道质量上报信息。或者，上述模式指示信息可用于指示第二终端设备在第二时间间隔内以上述第一时间间隔为发送间隔向第一终端设备发送第一信道质量指示信息。或者，上述模式指示信息可用于指示第二终端设备在第二时间间隔内向第一终端设备发送多次第一信道质量指示信息。并且每一次发送第一信道质量上报信息与上一次发送第一信道质量上报信息之间的时间间隔要小于或者等于上述第一时间间隔。
在另一种可选的实现种，上述信道质量评估请求中还可包括一个目标时刻。这里，该目标时刻可由第一终端设备根据当前时刻以及第一终端设备与第二设备之间的通信时延确定的。上述上报模式指示信息还可用于指示第二终端设备如何按照这个目标时刻来发送第一信道质量指示信息。例如，上报模式指示信息可指示第二终端设备在目标时刻之前发送一次或者多次第一信道质量指示信息。又例如，上报模式指示信息可指示第二终端设备在目标时刻上发送一次第一信道质量指示信息。
同时，上述信道质量评估请求中还可包括一个目标信道指示信息(又可称之为信道地图)。该目标信道指示信息指示了至少一个需要第二终端设备确定并上报信道质量参量的信道。该目标信道指示信息所指示的至少一个信道就包括有上述至少一个目标信道。具体实现中，上述目标信道指示信息中包括上述N1个信道中每个信道的信道标识以及每个信道对应的上报指示标识。这里，该上述指示标识有两个取值，分别是0和1。当某个信道对应的上报指示标识为1时，则表示需要第二终端设备确定并上报该信道的信道质量参量。当该信道的上报指示标识为0时，则表示不需要第二终端设备上报该信道的信道质量标识。这里，第一终端设备可指定第二终端设备仅对其需要的至少一个目标信道进行信道质量参量的确定和上报，一方面能够使得第二终端设备无需对所有的信道进行信道质量参量的确定，节省第二终端设备的数据处理量。另一方面也能使得后续第一终端设备无需对除目标信道以外的其他信道进行信道质量参量的提取，也能节省第一终端设备的数据处理量。
下面介绍本申请实施例提供的信道质量评估请求的三种具体的实现形式，包括实现形式一、实现形式二和实现形式三。

具体实现中，上述第一时间间隔可承载于LMP_channel_classification_req报文中的AFH_min_interval字段上，第二时间间隔可承载于LMP_channel_classification_req报文中的AFH_max_interval字段上。上报模式指示信息可承载于AFH_reporting_mode_ex字段上。下面请参见表1-3，表1-3是本申请实施例提供的一种AFH_reporting_mode_ex字段描述表格。如表1-3所示，AFH_reporting_mode_ex字段的长度可以为1个字节，数据格式为8位整型数。例如，能够指示的事件可包括AFH_reporting_disabled(即第二终端设备关闭主动上报第一信道质量上报信息的能力)事件、AFH_reporting_enabled(即第二终端设备开启主动上报第一信道质量上报信息的能力)事件、CQI Req(即第二终端设备在第二时间间隔内发送多多次第一信道质量上报信息，其发送间隔小于或者等于第一时间间隔)事件、format#1/2/3(即第一信道质量上报信息的格式为上述格式二、格式三、或者格式四)事件、CQI Immed Req#1/2(即第二终端设备在第一时间间隔或者第二时间间隔发送第一信道质量上报信息)事件、update min interval(更新第一时间间隔)事件以及update max interval(更新第二时间间隔)事件。AFH_reporting_mode_ex字段包括的8个比特可对应有0到255这256个取值，不同的取值对应指示上述一个或者多个事件。比如，AFH_reporting_mode_ex字段的取值为0时，可指示AFH_reporting_disabled事件。AFH_reporting_mode_ex字段的取值为1时，可指示AFH_reporting_enabled事件。AFH_reporting_mode_ex字段的取值为2到4时，可对应指示CQI Req with format #1/2/3这三个事件。这里，AFH_reporting_mode_ex字段的取值与其指示 的事件之间的对应关系具体可参见表中所描述内容，此处便不再一一赘述。其中，29到255这些取值作为预留取值，可供未来设计使用。

需要补充说明的是，在上述三种实现方式中，信道质量评估请求都关联有一个事件指示集合，该事件指示集合中记载了上述三种实现方式中所描述的一种或者多种事件与上报模式指示信息的不同取值之间的关系。比如，在实现方式一下，事件指示集合中可记载当上报模式指示信息用于指示第二终端设备开启第一信道质量上报信息的能力这一事件时，上报模式指示信息指示可取值为0。事件指示集合还可记载当上报模式指示信息用于指示第二终端设备在第一时间间隔内发送格式三下的第一信道质量上报信息这一事件时，上报模式指示信息指示可取值为13。
下面将结合前文叙述的信道质量评估请求的三种具体实现形式，对第一终端设备生成信道质量评估请求的过程进行简单的描述。
在一种具体的实现中，在确定生成并发送信道质量评估请求之前，第一终端设备可先确定出第一跳频地图所指示的至少一个可用信道(这里假设为N4，N4为大于或者等于1的正整数)。然后，第一终端设备可从其存储的信息历史记录中提取到其上一次接收到的来自于第二终端设备的信道质量上报信息(为了方便区别，下文将以第二信道质量上报信息代替描述)。然后，第一终端设备根据该第二信道质量上报信息所包括的各目标信道的信道质量参量从这至少一个目标信道中确定出N4个第一信道。例如，第一终端可将这至少一个目标信道中信道质量参量小于或者等于第一预设参量的信道作为第一信道。或者，第一终端设备也可按照信道质量参量对这至少一个目标信道进行排序，并取排序靠后的N4个信道作为第一信道。然后，第二终端设备可确定出上述N4个可用信道中，没有包含在上述N4个第二信道中的可用信道的个数(为了方便区别，下文将以第一个数代替描述)，再根据这第一个数来确定是否生成并向第二终端设备发送信道质量评估请求。可选的，一方面，当第一终端设备确定出上述第一个数等于或者大于第二预设个数时，其可确定生成并向第二终端设备发送信道质量评估请求。或者，第二终端设备可计算出第一个数与信道个数N1个比值(这里假设为D2)。当第二终端设备确定D2等于或者大于第二预设比值时，其可确定生成并向第二终端设备发送信道质量评估请求。另一方面，当第一终端设备确定上述第一个数小于第二预设个数或者D2小于第二预设比值时，第一终端设备可确定无需生成信道质量评估请求，其可重复上述确定各信道的信道质量以及后续的判断是否生成信道质量评估请求的操作。
在另一种具体实现中，在确定生成并发送信道质量评估请求之前，第一终端设备可确定其最近一次从第二终端设备处接收到的信道质量上报信息的时刻与当前时刻的时间间隔T1。当第一终端设备确定该时间间隔T1等于或者大于预设时间间隔，则确定生成并发送信道质量评估请求。若第一终端设备确定该时间间隔T1小于预设时间间隔，则继续上述确定时间间隔T1的操作。
这里，第一终端设备在确定其当前使用的第一跳频地图所指示的可用信道与第二终端设备上报的第二信道质量上报信息存在较大差异或者第二终端设备长期未上报信道质量评估结果的情况下，及时请求第二终端设备上报第一信道质量信息，可提升信道质量上报的时效性和有效性。并且，其后续也可根据第一信道质量上报信息快速的调整跳频地图，可提升第一终端所设计的跳频地图的时效性和准确性，从而提升跳频技术的抗干扰能力。
进一步的，在第一终端设备确定生成信道质量评估请求之后，其可先确定出第一信道质量上报信息对应的目标格式。具体实现中，若第一终端设备确定上述第一个数等于或者大于第三预设个数(该第三预设个数大于上述第二预设个数)，则可说明第二信道质量上报信息所指示的信道质量精度不够，则第一终端设备可确定目标格式可以是比上述第二信道质量上报信息的格式所对应的量化精度更高的格式。若第一终端设备确定上述第一个数大于第二预设 个数且小于第三预设个数，则可确定上述目标格式与第二信道质量上报信息的格式相同。若第一终端设备确定上述第一个数在第二预设个数和第三预设个数之间的次数达到预设次数，则确定目标格式可以是比第二信道质量上报信息的格式所对应的量化精度低的格式。例如，假设上述第二信道质量上报信息为上述格式二，若第一终端设备确定上述第一个数等于或者大于第三预设个数，则可确定上述目标格式可以为格式三或者格式四。若第一终端设备确定上述第一个数大于第二个数且小于第三预设个数，则可确定上述目标格式为格式二。若第一终端设备确定上述第一个数大于第二个数且小于第三预设个数的次数达到预设次数，则可确定上述目标格式为格式一。这里，第二终端设备最开始发送的信道质量上报信息的格式可优先指定为上述格式一或者格式二。
然后，可选的，在第一终端设备按照实现形式一中所描述内容生成信道质量请求的情况下，第一终端设备可获取到预设的第一时间间隔和第二时间间隔，并根据其与第二终端之间的业务状态来判断第二终端设备应该在什么时机发送第一信道质量上报信息。例如，若第一终端设备确定其与第二终端之间的业务状态为繁忙(即有较多的业务在进行)，则为了保证这些业务的正常执行，第一终端设备需要及时的调整跳频地图，因此，第一终端设备可要求第二终端设备在上述第一时间间隔内发送第一信道质量指示信息。若第一终端设备确定其与第二终端之间的业务状态为空闲(即有较少的业务在进行)，则第一终端设备无需即可调整跳频地图，因此，第一终端设备可要求第二终端设备在上述第二时间间隔内发送第一信道质量指示信息(是否以第一时间间隔为发送间隔均可)。当然，可以理解到的是，第一终端设备也可根据其与第二终端设备其他的状态信息(如数据传输状态信息)来确定第二终端设备应该在什么时机发送第一信道质量上报信息，本申请不作具体限制。另外，当第一终端设备发现第一时间间隔和/或第二时间间隔被更新时，其也可指示第二终端设备对其保存的第一时间间隔和/或第二时间间隔进行更新。其后，在第一终端设备确定出上述目标格式、第二终端设备发送第一信道质量上报信息的时机或者是否要对第一时间间隔和/或第二时间间隔进行更新等多个事件中的一个或者多个之后，第一终端设备可根据这些事件从上述取值指示集合中确定出上报模式指示信息的取值。然后，第一终端设备可将上报模式指示信息的取值保存在LMP_channel_classification_req报文中AFH_reporting_mode_ex字段中，并将第一时间间隔和第二时间间隔分别保存在LMP_channel_classification_req报文中的AFH_min_interval字段和AFH_max_interval字段上，以得到实现形式一下的信道质量评估请求。
可选的，在第一终端设备生成如上述实现形式二或者实现形式三中所描述的信道质量请求的情况下，第一终端设备可确定出目标时刻，并根据其与第二终端之间的业务状态来判断第二终端设备应该在什么时机发送第一信道质量上报信息。例如，若第一终端设备确定其与第二终端之间的业务状态为繁忙，则第一终端设备可确定第二终端设备应该在目标时刻之前发送第一信道质量指示信息。若第一终端设备确定其与第二终端之间的业务状态为空闲，则第一终端设备确定第二终端设备在目标时刻上发送第一信道质量指示信息。另外，在第一终端设备确定的目标信道指示信息和第一跳频地图等价的情况下，第一终端设备也可指示第二终端设备根据目标信道指示信息所指示的至少一个目标信道进行第二跳频地图的更新。然后，在第一终端设备确定出上述目标格式、第二终端设备发送第一信道质量上报信息的时机或者是否需要第二终端设备根据目标信道指示信息所指示的至少一个目标信道进行第二跳频地图更新等多个事件中的一个或者多个之后，第一终端设备可根据这些事件从上述取值指示集合中确定出上报模式指示信息的取值。
其后，第一终端设备可根据其对上述N1个信道中各信道进行信道质量估计得到的各信 道的信道质量测量值来确定出上述目标信道指示信息。这里，为了区别第一终端设备和第二终端设备对上述N1个信道进行信道质量估计得到的结果，后文中第二终端设备确定的各信道的信道质量测量值将由信道质量测量值代替描述，而第一终端设备确定的各信道的信道质量测量值将由第二信道质量测量值代替描述。具体的，第一终端设备在确定出各信道的第二信道质量测量值之后，可基于各信道的第二信道质量测量值的大小对这N1个信道进行排序，并确定这排序靠前的多个信道或者排序靠后的多个信道为需要第二终端设备上报信道质量参量的目标信道。其后，第二终端设备可将目标信道指示信息中这多个目标信道对应的上报指示标识调整为1，剩余的其他信道的上报指示标识调整为0，从而生成上述目标信道指示信息。
可选的，在第一终端设备需要第二终端设备进行信道质量上报的同时也需要第二终端设备基于第一终端设备的第一跳频地图进行第二跳频地图的这种特殊的场景下，第一终端设备也可将其当前的第一跳频地图确定为目标信道指示信息(即，目标信道指示信息与第一跳频地图可以复用，两者等价)。这样，上述目标信道指示信息所至少的至少一个目标信道也就是当前第一跳频地图所指示的至少一个可用信道。在这种场景下，一方面，第一终端设备可通过上述目标信道指示信息来告知第二终端设备上报上述至少一个目标信道的信道质量参量。另一方面，第一终端设备也可指示第二终端设备进行第二跳频地图的更新。具体的，可指示第二终端设备将第二跳频地图中包括的至少一个目标信道的可用性指示标识调整为1，即将第二跳频地图中这至少一个目标信道都确定为可用信道。这里，第一终端设备不仅可通过目标信道指示信息来指示第二终端设备上报这至少一个目标信道的信道质量参量，还能告知第二终端设备这至少一个目标信道也是其确定的可用信道，从而使得第二终端设备能够根据这至少一个目标信道进行第二跳频地图的更新。这样第一终端设备就无需再单独发送一个第一跳频地图来触发第二终端设备更新第二跳频地图，可节省第一终端设备和第二终端设备之间的通信资源。
然后，第一终端设备可将上述上报模式指示信息的取值保存在LMP_set_AFH报文中AFH_mode_ex字段内，并将目标时刻保存在AFH_instant字段上，将目标信道指示信息保存在AFH_channel_map字段上，以得到如上述实现形式二下的信道质量评估请求。或者，第一终端设备也可将上述上报模式指示信息的取值保存在CQI_req报文中的CQI_mode字段和CQI_format字段内，并将目标时刻保存在CQI_instant字段上，将目标信道指示信息保存在CQI_quality_map字段上，以得到如上述实现形式三下的信道质量评估请求。
在一些可行的实现方式中，第一终端设备在生成上述信道质量评估请求后，可随机从第一跳频地图所指示的至少一个可用信道中选择出一个第一目标可用信道。例如，第一终端设备可获取其包含的时钟模块输出的能够表征当前时刻的时间标识。这里，这个时钟模块输出的时间标识可以是绝对时间值。或者，时钟模块输出的时间标识也可以是一个计数值(即时钟模块本质上就是一个计数器，计数器输出的计数值就对应了不同的时刻)。然后，第一终端设备可以通过预设的随机数生成算法对上述时间标识进行处理，以得到第一跳频地图所指示的至少一个可用信道中某个可用信道的信道标识，从而将该信道标识对应的可用信道确定为第一目标可用信道。然后，第一终端设备可通过该目标可用信道将上述信道质量评估请求(即承载有上报模式指示信息等内容的LMP_channel_classification_req报文、LMP_set_AFH报文或者CQI_req报文)发送给第二终端设备。
在一些可行的实现方式中，第二终端设备也可以通过其关联的时钟模块所输出的时刻标识确定出上述第一目标可用信道。具体过程可参见步骤S1012中所描述的过程，此处便不再赘述。这里还需要说明的是，第一终端设备和第二终端设备所关联的时钟模块所输出的时间 标识应该完全一致，这样才能保证第一终端设备和第二终端设备在任意时刻都工作在同一个信道上。之后，第二终端设备即可通过第一目标可用信道接收来自于第一终端设备的信道质量评估请求。
下面将分别结合前文叙述的信道质量评估请求的三种实现形式，对第二终端设备生成第一信道质量上报信息的过程进行描述。
在上述实现形式一的场景下，第二终端设备在接收到上述信道质量评估请求后，可先对第一终端与第二终端设备之间的N1个信道进行信道质量估计，以得到N1个信道中各信道的信道质量测量值。这里，第二终端设备获取到各信道的信道质量测量值的过程可参见场景一中所描述的第二终端设备获取各信道的信道质量测量值的过程，此处便不再赘述。然后，第二终端设备可从上述信道质量评估请求中提取出上报模式指示信息、第一时间间隔或者第二时间间隔，并根据上述上报模式指示信息的取值以及上述取值指示集合确定出其将要生成的第一信道质量上报信息的格式(即为上述目标格式)以及其该在什么时机来发送上述第一信道质量评估请求。然后，第二终端设备可生成目标格式下的第一信道质量上报信息。这里，该目标格式为上述格式一、格式二、格式三或者格式四中的任一种。第二终端设备生成目标格式下的第一信道质量上报信息的过程可参见场景一中描述的第二终端设备生成格式一、格式二、格式三或者格式四下的第一信道质量上报信息的过程，此处便不再赘述。
在上述实现形式二或者实现形式三的场景下，第二终端设备可先从上述信道质量评估请求中提取出上报模式指示信息、目标时刻以及目标信道指示信息。然后，第二终端设备可根据上报模式指示信息的取值以及上述取值指示集合确定出其将要生成的第一信道质量上报信息的格式(即为上述目标格式)以及该第一信道上报指示信息所指示的至少一个目标信道。然后，第二终端设备可对上述至少一个目标信道进行信道质量估计，以得到各目标信道的信道质量测量值。这里，第二终端设备获取各目标信道的信道质量测量值的过程可参见场景一中所描述的第二终端设备获取各信道的信道质量测量值的过程，此处便不再赘述。之后，第二终端设备可生成目标格式下的第一信道质量上报信息。这里，该目标格式为上述格式一、格式二、格式三或者格式四中的任一种。该第一信道质量指示信息中包括各目标信道的信道质量参量。这里，第二终端设备生成目标格式下的第一信道质量上报信息的过程可参见场景一中描述的第二终端设备生成格式一、格式二、格式三或者格式四下的第一信道质量上报信息的过程，此处便不再赘述。
这里需要补充说明的是，当目标信道指示信息所指示的目标信道的个数大于第一终端设备所要求的格式下的第一信道质量上报信息所能够指示的信道的个数时，第二终端设备发送的第一信道质量上报信息中可仅包括目标信道指示信息所指示的所有目标信道中的部分目标信道。例如，假设目标信道指示信息指示的目标信道有50个，而上述目标格式为前文的格式二，则第二终端设备发送的第一信道质量上报信息中可包括上述50个目标信道中的前40个目标信道或者后40个目标信道。而当目标信道指示信息所指示的目标信道的个数小于第一终端设备所要求的格式下的第一信道质量上报信息所能够指示的信道的个数时，第二终端设备发送的第一信道质量上报信息中可包括目标信道指示信息所指示的所有目标信道以及N1个信道中除目标信道以外的一个或者多个信道的信道质量参量。此时，这一个或者多个信道的信道质量参量取值为0，即未知。例如，假设目标信道指示信息指示的目标信道有30个，而上述目标格式为前文的格式二，则第二终端设备发送的第一信道质量上报信息中可包括上述30个目标信道以及其他10个信道，这10个信道的信道质量参量为0。
这里，第二终端设备在接收到第一终端设备发送的信道质量评估请求后才会生成并发送 第一信道质量上报信息，可避免在第一终端没有需求的情况下向第一终端设备发送第一信道质量上报信息这种情况的发生，可避免第一终端设备和第二终端设备的通信资源的浪费。
在一些可行的实现方式中，第二终端设备在生成目标格式下的第一信道质量上报信息之后，可通过第二跳频地图所指示的第二目标可用信道将目标格式下的第一信道质量上报信息发送给第一终端设备。这里，第二终端设备从第二跳频地图所指示的至少一个可用信道中选择第二目标可用信道的过程可参见前文步骤S1012中描述的第一终端设备确定第一目标可用信道的过程，此处便不再赘述。
具体实现中，第二终端设备在生成目标格式下的第一信道质量上报信息之后，可先从第二跳频地图所指示的一个或者多个可用信道中随机选择出一个可用信道。然后，在上述场景一下，第二终端设备可在预定义的时刻上或者时间段内通过选择出的可用信道将目标格式下的第一信道质量上报信息发送给第一终端设备。在上述场景二下，第二终端设备可根据上述上报模式指示信息的取值以及事件指示集合确定出其发送第一信道质量上报信息的时机，并在相应的时机向第一终端设备发送目标格式一下的第一信道质量上报信息。例如，在信道质量评估请求采用上述实现形式一的情形下，第二终端设备在根据上述上报模式指示信息的取值以及事件指示集合确定其应该在第一时间间隔或者第二时间间隔内发送目标格式下的第一信道质量上报信息后，即可在第一时间间隔或者第二时间间隔内的一个或者多个随机的时间节点上向第一终端设备发送目标格式下的第一信道质量上报信息。或者，第二终端设备在根据上述上报模式指示信息的取值以及事件指示集合确定其应该在第二时间间隔内以第一时间间隔为发送间隔来发送目标格式下的第一信道质量上报信息之后，即可在第二时间间隔内以第一时间间隔为发送间隔向第一终端设备多次发送目标格式下的第一信道质量上报信息。又例如，在信道质量评估请求采用上述实现形式二或者实现形式三的情形下，第二终端设备在根据上述上报模式指示信息确定其应该在目标时刻上或者目标时刻之前发送第一信道质量上报信息后，若第二终端设备生成第一信道质量上报信息的时刻在上述目标时刻之后或者之上，则第二终端设备生成第一信道质量上报信息后就立即将第一信道质量上报信息发送给第一终端设备。若第二终端设备生成第一信道质量上报信息的时刻在上述目标时刻之前，则第二终端设备可在目标时刻之前的一个或者多个随机的时间节点上向第一终端设备发送目标格式一下的第一信道质量上报信息。
在一些可行的实现方式中，第一终端设备可通过上述第二目标可用信道接收第二终端设备发送的目标格式下的第一信道质量上报信息，并对上述第一信道质量上报信息进行解析，以获取到至少一个目标信道的信道质量参量。这里，第一终端设备从第一跳频地图所指示的至少一个可用信道中选择第二目标可用信道的过程可参见前文步骤S1012中描述的第一终端设备确定第一目标可用信道的过程，此处便不再赘述。
可选的，第一终端设备在获取到上述至少一个目标信道的信道质量参量后，还可根据这至少一个目标信道的信道质量参量以及其自身确定出的上述N1个信道中各信道的信道质量参量对其使用的第一跳频地图进行更新。第一终端设备根据第二终端设备上报的精度合适的信道质量参量进行第一跳频地图的更新，可保证第一跳频地图的精度，提升跳频技术的抗干扰能力。后文中为了区别第一终端设备或者第二终端设备获取到信道质量测量值和信道质量测量值，针对第二终端设备获取到信道质量测量值和信道质量测量值将以第一信道质量测量值和第一信道质量参量代替描述。针对第一终端设备获取到信道质量测量值和信道质量测量值将以第二信道质量测量值和第二信道质量参量代替描述。
具体实现中，第一终端设备可对上述第一信道质量上报信息所指示的至少一个目标信道 中各目标信道进行信道质量估计，以得到各目标信道的第二信道质量测量值。具体过程可参见前文叙述的第二终端设备确定各信道的信道质量测量值的过程，此处便不再赘述。然后，第一终端设备可通过目标格式对应的量化规则(为前文叙述的第一量化规则、第二量化规则、第三量化规则或者第四量化规则)对各目标信道的第二信道质量测量值进行量化处理，以得到各目标信道的第二信道质量参量。具体量化过程可参见前文叙述的第二终端设备对信道质量测量值的量化过程，此处便不再赘述。在第一终端设备获取到各目标信道的第一信道质量参量和第二信道质量参量之后，即可可根据各目标信道的第一信道质量参量和第二信道质量参量对各目标信道进行可用性判定，以确定各目标信道是否为可用信道。下面将根据目标格式的不同，对第二终端设备根据各目标信道的第一信道质量参量和第二信道质量参量对各目标信道进行可用性判定的过程作简单的描述。
在目标格式为上述格式一、格式二或者格式三的情况下，在一种可选的实现中，若第二终端设备确定某一个目标信道的第一信道质量参量和第二信道质量参量均指示该目标信道的信道质量为好(即第一信道质量参量和第二信道质量参量的取值都为1)，则可确定该目标信道为可用信道。若第二终端设备确定某一个目标信道的第一信道质量参量和/或第二信道质量参量指示该目标信道的信道质量为未知、差或者适用(即第一信道质量参量和/或第二信道质量参量的取值不为1)，则可确定该目标信道为不可用信道。在另一种可选的实现中，若第二终端设备确定某一个目标信道的第一信道质量参量和第二信道质量参量均指示该目标信道的信道质量为差(即第一信道质量参量和第二信道质量参量的取值都为1或者3)，则可确定该目标信道为不可用信道。若第二终端设备确定某一个目标信道的第一信道质量参量和/或第二信道质量参量指示该目标信道的信道质量为未知、好或者适用(即第一信道质量参量和/或第二信道质量参量的取值不为1或者3)，则可确定该目标信道为可用信道。
可选的，当第一终端设备确定出上述至少一个目标信道中的可用信道的个数小于预设的最小可用信道个数时，则可进行可用信道的补选。这里，上述最小可用信道个数是第一终端设备和第二终端设备的通信标准中预定义的，比如，在蓝牙标准规定的BR/EDR模式下，这个最小可用信道个数为20。具体实现中，第一终端设备可基于N1个信道中各信道的第二信道质量测量值对各信道进行排序，然后选择被判定为不可用信道但是排序靠前的一个或者多个信道来对可用信道进行补充，从而使得当前的可用信道的个数达到或者大于最小可用信道个数。又或者，第一终端设备可将N1个信道中被第二终端设备评估为信道质量为差信道剔除掉，然后将剩余的信道基于第二信道质量测量值进行排序，然后从中选择不是可用信道但是排序靠前的一个或者多个信道来对可用信道进行补充。
在目标格式为上述格式四的情况下，由于目标信道对应的信道质量参量有很多个层次，所以第一终端设备可计算出各目标信道对应的第一信道质量参量和第二信道质量参量的平均值，再将至少一个目标信道中第一信道质量参量和第二信道质量参量的平均值等于或者大于第一预设均值的目标信道确定为可用信道，将至少一个目标信道中第一信道质量参量和第二信道质量参量的平均值小于第一预设均值的目标信道确定为不可用信道。或者，第一终端设备也可结合预设的权重计算出各目标信道对应的第一信道质量参量和第二信道质量参量的加权平均值。这里，对于每个目标信道来说，其第一信道质量参量和第二信道质量参量都对应有一个权重值。例如，假设目标信道3的第一信道质量参量和第二信道质量参量和权重为0.7和0.3。若其第一信道质量餐参量为5，第二信道质量参量为7，则其第一信道质量参量和第二信道质量参量的加权平均值为5*0.7+7*0.3＝5.6。然后，第一终端设备可将第一信道质量参量和第二信道质量参量的加权平均值等于或者大于第二预设均值的目标信道确定为可用信 道，并将第一信道质量参量和第二信道质量参量的平均值小于第一预设均值的目标信道确定为可用信道。
可选的，当第一终端设备确定出上述至少一个目标信道中的可用信道的个数小于预设的最小可用信道个数时，也需要进行可用信道的补选。具体的，第一终端设备基于各目标信道的第一信道质量参量和第二信道质量参量的平均值或者加权平均值对各目标信道进行排序，然后选择排序靠前但被确定为不可用信道的目标信道来对可用信道进行补充，以使得补充后的可用信道的个数能等于或者大于最小可用信道个数。
当第一终端设备完成对各目标信道的可用性判定之后，第一终端设备可根据各目标信道的可用性判定的结果对当前使用的第一跳频地图进行更新，以得到更新后的第一跳频地图。具体的，第一终端设备可根据各目标信道的可用性判定的结果对第一跳频地图中包括的上述至少一个目标信道的可用性指示标识进行调整。例如，第一终端设备可将第一跳频地图中被确定为可用信道的目标信道的可用性指示标识调整为1，被确定为不可用信道的目标信道的可用性指示标识调整为0。
进一步的，在第一终端设备确定出更新后的第一跳频地图后，其可将更新后的第一跳频地图发送给第二终端设备。第二终端设备在接收到上述更新后的第一跳频地图后，可将这个更新后的第一跳频地图作为其新的第二跳频地图，从而完成其对第二跳频地图的更新。在第一终端设备和第二终端设备分别完成第一跳频地图和第二跳频地图的更新后，第一终端设备和第二终端设备即可采用更新后的第一跳频地图和第二跳频地图所指示的可用信道进行通信。
在本实施例中，第二终端设备可适应性的向第一终端设备发送不同精度的第一信道质量上报信息给第一终端设备设备，提升了信道质量上报的灵活度。进一步的，第一终端设备基于精度合适的第一信道质量上报信息能够设计出更为准确的第一跳频地图，可提升跳频技术的抗干扰能力。
