技术领域
本申请涉及智能终端技术领域，尤其涉及一种发射功率调整方法、电子设备及存储介质。
背景技术
当耳机与电子设备间的连接出现干扰较大的情况时(如耳机距离电子设备较远时)，耳机会请求电子设备提高发射功率，从而保证耳机与电子设备间的通信质量。但是有些耳机为了保证收音的效率，提高用户的听觉体验，不会考虑实际的通信情况，会一直请求电子设备提高发射功率，直至电子设备将发射功率升至最高发射功率时，才会停止发送提高发射功率请求。电子设备也会直接基于耳机的请求，将发射功率升至最高发射功率。然而，耳机的部分应用场景并不需要那么高的发射功率，所以容易导致功耗的浪费。
发明内容
鉴于以上内容，有必要提供一种发射功率调整方法、电子设备及存储介质，在耳机请求提高发射功率时，通过对应用场景进行判断从而确定是否提高发射功率，可以避免电子设备依据蓝牙播放设备提出的不合理发射功率提高请求，提高发射功率，导致功耗浪费的情况发生。

在一种可能的实现方式中，所述方法还包括：若当所述电子设备与所述蓝牙播放设备的通信质量不满足预设通信阈值，提高发射功率。通过上述技术方案，可以在通信质量不好的情况下提高发射功率，保证电子设备与蓝牙播放设备之间通信的质量。
在一种可能的实现方式中，所述方法还包括：若所述电子设备与所述蓝牙播放设备的通信质量满足预设通信阈值，向所述蓝牙播放设备发送提高信令或最高功率信令，所述提高信令用于在没有提高发射功率时告知所述蓝牙播放设备已提高发射功率；所述最高功率信令用于在没有达到最高发射功率时告知所述蓝牙播放设备已达到最高发射功率。通过上述技术方案，可以拒绝蓝牙播放设备不合理的发射功率提高请求，通过发送最高功率信令可以避免后 续蓝牙播放设备在通信质量正常的情况下继续向电子设备请求提高发射功率的行为出现。
在一种可能的实现方式中，所述若确定与所述蓝牙播放设备的通信质量满足预设通信阈值，向所述蓝牙播放设备发送提高信令包括：计算接收所述蓝牙播放设备发送的提高发射功率请求后确定不提高发射功率的次数；若所述次数满足预设数量条件，向所述蓝牙播放设备发送提高信令或最高功率信令。通过上述技术方案，可以拒绝蓝牙播放设备不合理的发射功率提高请求，通过发送最高功率信令可以避免后续蓝牙播放设备在通信质量正常的情况下继续向电子设备请求提高发射功率的行为出现。
在一种可能的实现方式中，所述向所述蓝牙播放设备发送提高信令后，所述方法还包括：若向所述蓝牙播放设备发送提高信令的次数大于或等于预设次数，向所述蓝牙播放设备发送最高功率信令。通过上述技术方案，可以避免后续蓝牙播放设备在通信质量正常的情况下继续向电子设备请求提高发射功率的行为出现。
在一种可能的实现方式中，所述方法还包括：若确定与所述蓝牙播放设备的通信质量满足预设通信阈值，向所述蓝牙播放设备发送拒绝信令，所述拒绝信令用于告知所述蓝牙播放设备未提高发射功率。通过上述技术方案，可以拒绝蓝牙播放设备不合理的发射功率提高请求。
在一种可能的实现方式中，若确定与所述蓝牙播放设备的通信质量满足预设通信阈值，向所述蓝牙播放设备发送拒绝信令之后，所述方法还包括：若连续发送拒绝信令的次数大于或等于预设拒绝次数，向所述蓝牙播放设备发送提高信令或最高功率信令。通过上述技术方案，可以拒绝蓝牙播放设备不合理的发射功率提高请求，通过发送最高功率信令可以避免后续蓝牙播放设备在通信质量正常的情况下继续向电子设备请求提高发射功率的行为出现。
在一种可能的实现方式中，若连续发送拒绝信令的次数大于或等于预设拒绝次数，向所述蓝牙播放设备发送提高信令之后，所述方法包括：若向所述蓝牙播放设备发送提高信令的次数大于预设次数，向所述蓝牙播放设备发送最高功率信令。通过上述技术方案，可以避免后续蓝牙播放设备在通信质量正常的情况下继续向电子设备请求提高发射功率的行为出现。

具体实施方式
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请实施例的描述中，“示例性”、“或者”、“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性”、“或者”、“例如”等词旨在以具体方式呈现相关概念。
除非另有定义，本文所使用的所有的技术和科学术语与属于本申请中的技术领域的技术人员通常理解的含义相同。本申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请。应理解，本申请中除非另有说明，“/”表示或的意思。例如，A/B可以表示A或B。本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系。例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B三种情况。“至少一个”是指一个或者多个。“多个”是指两个或多于两个。例如，a、b或c中的至少一个，可以表示：a，b，c，a和b，a和c，b和c，a、b和c七种情况。应当理解的是，本文的流程图中所示步骤的顺序可以改变，某些也可以省略。
如图1所示，耳机在与电子设备间的连接出现干扰较大的情况时(如耳机距离电子设备较远时)，耳机会请求电子设备提高发射功率，但是有些耳机在连接电子设备后，不会考虑实际的情况，会一直向电子设备请求提高发射功率，直至电子设备将发射功率升至电子设备的最高发射功率，如最高发射功率为Powerlever 10对应的功率。上述期间，耳机会一直向电子设备发送提高发射功率请求，直到电子设备的发射功率提高至Powerlever 10对应的功率，才会停止发送提高发射功率请求。电子设备会基于耳机的请求，将发射功率升至最高，如将发射功率提高至Powerlever 10对应的功率。然而，有时候耳机的应用场景并不需要那么高的发射功率，上述过程和结果必然会造成功耗的浪费。
为了解决上述过程中电子设备根据耳机提高发射功率请求一直提高发射功率，从而造成功耗的浪费行为，本申请实施例提供一种发射功率调整方法，以避免在耳机处于音乐场景时持续提高发射功率而造成的功耗异常提高的问题。具体地，本申请实施例可以在耳机请求提高发射功率时，通过对应用场景进行判断从而确定是否提高发射功率，可以避免电子设备依据耳机提出的不合理发射功率提高请求提高发射功率而提高导致的功耗浪费。
可以理解的是，本申请中的电子设备可以是手机、平板电脑、桌面型计算机、膝上型计算机、手持计算机、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本，以及蜂窝电话、个人数字助理(personal digital assistant，PDA)、人工智能(artificial intelligence，AI)设备、可穿戴式设备、车载设备、智能家居设备和/或智慧城市设备等电子设备。本申请实施例对该设备的具体形态不作特殊限制。本申请中的耳机也可以是其他的蓝牙播放设备，如蓝牙音箱等。
下面结合附图，对本申请提供的发射功率调整方法进行详细介绍。
图2为耳机与电子设备之间进行信令交互的一种示意图。如图2所示，耳机可以通过向电子设备发送LMP-INCR-POWER-REQ信令以请求电子设备提高发射功率。电子设备会基于耳机发送的LMP-INCR-POWER-REQ信令提高发射功率。具体地，电子设备根据LMP-INCR-POWER-REQ信令对应的发射功率提高值对发射功率进行提高，可以理解的是，不同LMP-INCR-POWER-REQ信令可以对应相同或不同的发射功率提高值，LMP-INCR-POWER-REQ信令对应的发射功率提高值可以根据实际情况进行设置，在此不做任何限定。
若电子设备接收到耳机发送的LMP-INCR-POWER-REQ信令且确定当前的发射功率为最高发射功率(如最高发射功率为Powerlever 10对应的功率)时，电子设备向耳机发送LMP-MAX-POWER信令，告知耳机当前电子设备的发射功率为最高发射功率，不能继续提高功率请求。耳机接收到LMP-MAX-POWER信令时，会停止向电子设备发送提高功率请求。
电子设备根据LMP-INCR-POWER-REQ信令对应的发射功率提高值对发射功率进行提高。可以理解的是，LMP-INCR-POWER-REQ信令对应的发射功率提高值可以根据实际情况进行设置，不同的两个LMP-INCR-POWER-REQ信令可能对应不同的发射功率提高值，在此不做任何限定。
在图2所示的信令交互过程中，耳机会一直向电子设备发送LMP-INCR-POWER-REQ信令，以使电子设备的发射功率提高至最高发射功率。为解决上述问题，本申请实施例提供了图3所示的一种发射功率调整方法。该方法应用于电子设备。所述电子设备可以包括蓝牙固件(Blutooth Controller，BTC)，该方法可以应用在电子设备的BTC上。电子设备与耳机建立蓝牙连接，如图3所示，该方法可以包括：
301，接收耳机发送的LMP-INCR-POWER-REQ信令。
LMP-INCR-POWER-REQ信令用于请求电子设备提高发射功率。可以理解的是，该处的LMP-INCR-POWER-REQ信令仅做举例说明，耳机还可以通过发送其他的指令，请求电子设备提高发射功率。
302，确定与耳机的通信质量是否满足预设通信阈值。
电子设备接收耳机发送的LMP-INCR-POWER-REQ信令后，电子设备确定与耳机的通信质量，并确定与耳机的通信质量是否满足预设通信阈值。
在本申请的一些实施例中，所述通信质量包括重传率，重传率用于确定电子设备向耳机 进行数据传输的效率，可以为电子设备向耳机重新传输信号的概率。所述确定与耳机之间的通信质量是否满足预设通信阈值包括：确定与耳机的重传率是否小于或等于所述重传率阈值；若确定与耳机之间的重传率小于或等于所述重传率阈值，确定与耳机之间的通信质量满足预设通信阈值；若确定与耳机之间的重传率大于所述重传率阈值，确定与耳机之间的通信质量不满足预设通信阈值。
重传率阈值可以根据实际情况进行设置，如设置为50％。若电子设备确定与耳机之间的重传率小于或等于50％，电子设备确定与耳机之间的通信质量满足预设通信阈值。若电子设备确定与耳机之间的重传率大于50％，电子设备确定与耳机之间的通信质量不满足预设通信阈值。
在本申请的一些实施例中，所述通信质量包括耳机的接收信号的强度指示(Received Signal Strength Indicator，RSSI)，所述确定与耳机之间的通信质量是否满足预设通信阈值包括：确定与耳机的RSSI是否小于或等于强度阈值；若电子设备确定耳机的RSSI小于或等于强度阈值，电子设备确定与耳机之间的通信质量不满足预设通信阈值。若电子设备确定耳机的RSSI大于所述强度阈值，电子设备确定与耳机之间的通信质量满足预设通信阈值。
在本申请的一些实施例中，所述通信质量包括耳机的误码率，误码率可以为耳机向电子设备传输信号的误码概率。所述确定与耳机之间的通信质量是否满足预设通信阈值包括：确定与耳机的误码率是否小于或等于误码率阈值；若电子设备确定耳机的误码率小于或等于误码率阈值，电子设备确定与耳机之间的通信质量满足预设通信阈值。若电子设备确定耳机的误码率大于所述误码率阈值，电子设备确定与耳机之间的通信质量不满足预设通信阈值。
若确定与耳机的通信质量满足预设通信阈值，执行303，不提高发射功率。若确定与耳机的通信质量满足预设通信阈值，执行304，提高发射功率。
如图3所示，电子设备当前的发射功率以Power Level 7对应的功率为例进行说明，若确定与耳机的通信质量满足所述预设通信阈值，不提高发射功率，即保持当前的发射功率Power Level 7对应的功率；若确定与耳机的通信质量不满足预设通信阈值，将当前的发射功率从Power Level 7对应的功率提高至Power Level 8对应的功率。在本申请的一些实施例中，图3中302，确定与耳机的通信质量是否满足预设通信阈值之后，所述方法还包括：统计接收耳机发送的LMP-INCR-POWER-REQ信令后不提高发射功率的次数；若所述次数满足预设数量条件，向所述耳机发送LMP-MAX-POWER信令。
LMP-MAX-POWER信令用于表示电子设备当前的发射功率为最高发射功率，不能继续提高发射功率，可以告知耳机：电子设备已为最高发射功率，无法再提高发射功率。通过向耳机发送LMP-MAX-POWER信令，可以阻止耳机继续向电子设备发送发射功率提高请求。可以理解的是，该处的LMP-MAX-POWER信令仅做举例说明，电子设备还可以通过向耳机发送其他的指令，将其当前的发射功率为最高发射功率，不能继续提高发射功率的情况告知耳机，从而避免耳机继续向电子设备发送发射功率提高请求。
可以统计电子设备与耳机连接后，电子设备接收耳机发送的LMP-INCR-POWER-REQ信令后不提高发射功率的次数。或者，可以统计在预设时间段内，接收耳机发送的LMP-INCR-POWER-REQ信令后不提高发射功率的次数。所述预设时间段可以根据实际情况进行设置。例如，预设时间段可以包括电子设备上一次提高发射功率的时间到当前时间的时间段。当电子设备与耳机建立蓝牙连接后并未提高过发射功率时，预设时间段也可以包括电子设备与耳机建立蓝牙连接的时间到当前时间的时间段。
预设数量条件可以包括预设数量阈值，上述判断次数是否满足预设数量条件包括：判断次数是否大于或等于预设数量阈值，预设数量阈值可以根据实际情况进行设置，在此不作任何限定，例如预设数量阈值可以设置为1、2或3等。
在本申请的一些实施例中，将预设数量阈值设置为1时，所述方法包括：若接收耳机发送的LMP-INCR-POWER-REQ信令后确定与耳机的通信质量满足预设通信阈值，向所述耳机发送LMP-MAX-POWER信令。也就说，在第一次接到耳机发送的LMP-INCR-POWER-REQ信令后确定与耳机的通信质量满足预设通信阈值时，直接向耳机发送LMP-MAX-POWER信令，以阻止耳机继续向电子设备发送发射功率提高请求。在第一次发现耳机会在通信质量正常的情况下向电子设备请求提高发射功率这一行为时，直接向耳机发送LMP-MAX-POWER信令，可以避免后续耳机在通信质量正常的情况下继续向电子设备请求提高发射功率的行为出现。
当预设数量阈值的值设置得较大时，若接收耳机发送的LMP-INCR-POWER-REQ信令后不提高发射功率的次数满足预设数量条件，可确定如下情况：耳机在通信质量满足预设通信阈值时向电子设备请求提高发射功率的请求次数较多。当耳机在通信质量满足预设通信阈值时向电子设备请求提高发射功率的请求次数较多的情况下，向耳机发送LMP-MAX-POWER信令，可以避免耳机在通信质量满足预设通信阈值时一直向电子设备请求提高发射功率的情况发生。同时，确定耳机在通信质量满足预设通信阈值时向电子设备请求提高发射功率的请求次数较多的情况下，再通过向耳机发送LMP-MAX-POWER信令以阻止耳机继续发送提高发射功率的请求，可以避免耳机偶然一次在通信质量满足预设通信阈值时向电子设备请求提高发射功率后就直接拒绝耳机向电子设备请求提高发射功率的机会，导致耳机无法正常地向电子设备请求提高发射功率的情况发生。
上述实施例，在耳机请求提高发射功率时，根据与耳机的通信质量确定是否提高发射功率，并在确定与耳机的重传率满足预设提高条件时提高电子设备的发射功率，可以避免电子设备依据耳机提出的不合理发射功率提高请求时进行发射功率提高导致的功耗浪费。
接收耳机发送的LMP-INCR-POWER-REQ信令后不提高发射功率的次数满足预设数量条件，向所述耳机发送LMP-MAX-POWER信令时，电子设备的发射功率实际上可能未达到电子设备的最高发射功率。下面结合实施例，电子设备向耳机发送LMP-MAX-POWER信令后的一些具体实施方式进行说明。
在本申请的一些实施例中，向所述耳机发送LMP-MAX-POWER信令后，所述方法还包括：按照预设的时间间隔，确定与耳机的通信质量是否满足预设通信阈值。若确定与耳机的通信质量不满足预设通信阈值，主动提高发射功率。若确定与耳机的通信质量满足预设通信阈值，不做任何处理，流程结束。可以理解的是，可以在电子设备当前发射功率不是最高发射功率却向耳机通知当前发射功率为最高发射功率时执行上述方法。若电子设备当前发射功率是最高发射功率，则不会执行上述方法。
通过上述方法，可以避免电子设备当前发射功率不是最高发射功率却向耳机通知当前发射功率为最高发射功率时执行上述方法后，当电子设备的当前发射功率不能满足与耳机的正常通信时，由于电子设备不会主动提高发射功率而导致电子设备与耳机之间的传输效率低的情况发生，从而提高了发射功率调节的准确率。
图2所示的耳机与电子设备之间进行信令交互时，电子设备每次接收耳机发送的发射功率提高请求后，会直接根据请求提高发射功率，除当前发射功率为最高发射功率的情形下， 都不会对耳机的发射功率请求进行答复。但是在一些实施例中，电子设备每次接收到耳机发送的发射功率提高请求后，都会对耳机的发射功率提高请求进行答复，如图4所示。图4为耳机与电子设备之间进行信令交互的一种示意图。如图4所示，耳机可以通过向电子设备发送LL-POWER-CONTROL-REQ信令以请求电子设备提高发射功率。电子设备会基于耳机发送的LL-POWER-CONTROL-REQ信令提高发射功率，并在发射功率提高后，向耳机发送LL-POWER-CONTROL-RSP指令。
如表1所示，LL-POWER-CONTROL-REQ信令中可以包括三个控制参数(Control Data，CtrData)：物理信道(physical，PHY)、差值(Delta)、发射功率(TxPower)。其中，PHY用于表示信令发送使用的信号。Delta用于表示请求改变的发射功率值，正数表示请求提高的发射功率值，负数表示请求降低的发射功率值。例如，Delta 1表示请求提高1db的发射功率，Delta-1表示请求降低1db的发射功率。TxPower表示本端的当前发射功率。若一个耳机发出了LL-POWER-CONTROL-REQ信令，指令中的TxPower表示该耳机的当前发射功率。
表1
Figure PCTCN2022139107-appb-000001
如表2所示，LL-POWER-CONTROL-RSP信令中可以包括六个控制参数(Control Data，CtrData)：最小值(Min)；最大值(Max)；保留位(Reserved for future use，RFU)；差值(Delta)、发射功率(TxPower)，可接受的最大功率降低值(Acceptable Power Reduction，APR)。其中，Min用于表示当前是否为最小发射功率，Min 0表示当前不为最小发射功率，Min 1表示当前为最小发射功率。Max用于表示当前是否为最大发射功率，Max 0表示当前不为最大发射功率，Max 1表示当前为最大发射功率。Delta用于表示本次改变的发射功率值，正数表示本次提高的发射功率值，负数表示本次降低的发射功率值。例如，Delta 1表示本次提高1db的发射功率，Delta-1表示本次降低1db的发射功率。TxPower表示本端的当前发射功率。若一个电子设备发出了LL-POWER-CONTROL-RSP信令，指令中的TxPower表示该电子设备的当前发射功率。
表2
Figure PCTCN2022139107-appb-000002
为了方便描述，在图4所示的信令交互中，加入了各个信令中的关键控制参数用于表示每个信令对应的具体内容。例如，LL-POWER-CONTROL-REQ(Delta 1)用于表示耳机向电子设备请求提高1db的发射功率。LL-POWER-CONTROL-RSP(Max 0，Delta 1，Txpower 8)表示电子设备已根据LL-POWER-CONTROL-REQ(Delta 1)信令提高了1db的发射功率(Delta1)，当前电子设备的发射功率为power lever8对应的功率(Txpower 8)，且当前电子的发射功率不为最大发射功率(Max 0)。
若电子设备提高发射功率后，确定当前的发射功率为最高发射功率(如最高发射功率为Powerlever 10对应的功率)时，电子设备向耳机发送LL-POWER-CONTROL-RSP(Max 1，Delta 1，Txpower 10)信令，告知耳机已根据LL-POWER-CONTROL-REQ信令提高了1 db的发射功率(Delta 1)，当前电子设备的发射功率为Powerlever 10对应的功率，是最高发射功率(Max 1)，不能继续提高功率请求。耳机接收到Max为1的LL-POWER-CONTROL-RSP 信令时，会停止向电子设备发送提高功率请求。
在图4所示的信令交互过程中，耳机会一直向电子设备发送LL-POWER-CONTROL-REQ信令，以使电子设备的发射功率提高至最高发射功率。为解决上述问题，本申请实施例提供了图5所示的一种发射功率调整方法。该方法应用于电子设备。所述电子设备可以包括蓝牙固件(Blutooth Controller，BTC)，该方法可以应用在电子设备的BTC上。电子设备与耳机建立蓝牙连接，如图5所示，该方法可以包括：
501，接收LL-POWER-CONTROL-REQ信令。
例如，LL-POWER-CONTROL-REQ(Delta 1)信令用于请求电子设备提高1db的发射功率。
502，确定与耳机的通信质量是否满足预设通信阈值。
接收耳机发送的LL-POWER-CONTROL-REQ信令后，电子设备确定与耳机的通信质量，并确定与耳机的通信质量是否满足预设通信阈值。
若确定与耳机的通信质量满足预设通信阈值，执行503，不提高发射功率；若确定与耳机的通信质量满足预设通信阈值，执行504，提高发射功率。
电子设备基于LL-POWER-CONTROL-REQ信令提高发射功率后，可以向耳机发送LL-POWER-CONTROL-RSP信令，如LL-POWER-CONTROL-RSP(Max 0，Delta 1，Txpower 8)。如图5所示，电子设备当前的发射功率以Power Level 7对应的功率为例进行说明，若确定与耳机的通信质量满足所述预设通信阈值，不提高发射功率，即，保持当前的发射功率Power Level 7对应的功率；若确定与耳机的通信质量不满足预设通信阈值，将当前的发射功率从Power Level 7对应的功率提高至Power Level 8对应的功率。
上述实施例，在耳机请求提高发射功率时，根据与耳机的通信质量确定是否提高发射功率，并在确定与耳机的重传率满足预设提高条件时，提高电子设备的发射功率，可以避免电子设备依据耳机提出的不合理发射功率提高请求时进行发射功率提高导致的功耗浪费。
在本申请的一些实施例中，如图6所示，图5中502，确定与耳机的通信质量是否满足所述预设通信阈值之后，电子设备若确定与耳机的通信质量满足所述预设通信阈值，执行601，向耳机发送拒绝信令。拒绝信令表示拒绝根据提高发射功率请求对发射功率进行提高，可以用于告知所述蓝牙播放设备未提高发射功率。如图7所示，电子设备接收LL-POWER-CONTROL-REQ信令前的发射功率为Powerlever 7对应的功率，电子设备确定与耳机的通信质量满足所述预设通信阈值之后，向耳机发送LL-POWER-CONTROL-RSP(Max 0，Delta 0，Txpower 7)，其中Delta 0表示未根据LL-POWER-CONTROL-REQ信令提高发射功率。可以理解的是，若下一次电子设备再接收LL-POWER-CONTROL-REQ信令且确定与耳机的通信质量仍满足所述预设通信阈值时，电子设备继续向耳机发送拒绝信令，即发送LL-POWER-CONTROL-RSP(Max 0，Delta 0，Txpower 7)。
在本申请的一些实施例中，执行图5中502，确定与耳机的通信质量是否满足所述预设通信阈值之后，电子设备可以统计接收耳机发送的LL-POWER-CONTROL-REQ信令后不提高发射功率的次数；若所述次数满足预设数量条件，向所述耳机发送提高信令。
其中，统计接收耳机发送的LL-POWER-CONTROL-REQ信令后不提高发射功率的次数的一些具体实施方式可以参见对图3中统计接收耳机发送的LMP-INCR-POWER-REQ信令后不提高发射功率的次数的相关描述，预设数量条件也可以参见与图3实施例相关的描述，在此不再赘述。
在本申请的一些实施例中，可以将电子设备向耳机发送的拒绝信令的次数，确定为接收耳机发送的LL-POWER-CONTROL-REQ信令后不提高发射功率的次数。
提高信令用于告诉耳机已提高发射功率。可以理解的是，发射功率未提高时发送的提高信令可以和发射功率提高时发送的提高信令格式一致，也可以有所不同。当耳机接收到发射功率提高时发送的提高信令和发射功率未提高时发送的提高信令时，都能确定电子设备已提高发射功率。例如，一电子设备的发射功率为Powerlever 7对应的功率时，当该电子设备接收到LL-POWER-CONTROL-REQ(Delta 1)信令时，确定在上一次提高发射功率到当前时间的时间段内，与耳机的通信质量符合预设通信阈值的次数满足预设数量条件，如确定拒绝信令的连续发送次数大于或等于预设拒绝次数阈值，不提高发射功率，直接向耳机发送LL-POWER-CONTROL-RSP(Max 0，Delta 1，Txpower 8)，告知耳机已根据LL-POWER-CONTROL-REQ(Delta 1)信令提高了1db的发射功率，当前电子设备的发射功率为power lever8对应的功率，且当前电子设备的发射功率不为最大发射功率，实际上电子设备未提高发射功率，电子设备的当前发射功率仍为power lever7对应的功率。
可以理解的是，电子设备不提高发射功率且向耳机发送提高信令后，若再一次收到LL-POWER-CONTROL-REQ信令且确定与耳机的通信质量满足预设通信阈值时，依然不提高发射功率，并继续向耳机发送一次提高信令。可以理解的是，在电子设备不提高发射功率的情况下，电子设备在不同时间内发送的提高信令可以有所不同。例如，在电子设备不提高发射功率的情况下，电子设备A向耳机A第一次发送的提高信令可以为LL-POWER-CONTROL-RSP(Max 0，Delta 1，Txpower 8)，电子设备A向耳机A第二次发送的提高信令可以为LL-POWER-CONTROL-RSP(Max 0，Delta 1，Txpower 9)，其中，第一次的发送时间早于第二次的发送时间。也就是说，在电子设备不提高发射功率的情况下，该电子设备向同一耳机发送的多次提高信令可以有所不同。例如，发送时间在后的提高信令中的Txpower值可以大于发送时间在前的提高信令中的Txpower值。在电子设备不提高发射功率的情况下，向耳机发送不同的提高信令，可以避免一直向耳机发送相同的提高信令导致耳机报错的情况发生。
进一步地，在本申请的一些实施例中，若在不提高功率的情况下向耳机发送提高信令的次数大于预设次数，向耳机发送最高功率信令。通过向耳机发送最高功率信令，以避免耳机一直向电子设备请求提高发射功率。
最高功率信令用于告诉耳机：电子设备当前的发射功率为最高发射功率，不能继续提高发射功率。通过在电子设备实际发射功率不是最高发射功率时，向耳机发送最高功率信令(如发送LL-POWER-CONTROL-REQ信令)，可以阻止耳机继续向电子设备发送发射功率提高请求。例如，最高功率信令可以为LL-POWER-CONTROL-RSP(Max 1，Delta A，Txpower B)，Max 1表示电子设备当前的发射功率为最高发射功率，A为大于0的数，A为告知耳机提高的发射功率值(实际电子设备可以未提高发射功率)，A的具体值可以根据实际情况进行设置。耳机可以根据指令中的Txpower B确定电子设备的发射功率，所以B的取值应大于耳机上一次知道的电子设备的发射功率。例如，若电子设备上一次向耳机发送的信令为LL-POWER-CONTROL-RSP(Max 0，Delta 1，Txpower 7)，电子设备该次向耳机发送的最高功率信令可以为LL-POWER-CONTROL-RSP(Max 1，Delta A，Txpower B)，其中B的值应大于7，B的值可以等于A的值加上7。
可以理解的是，在本申请的一些实施例中，电子设备可以统计接收耳机发送的LL-POWER -CONTROL-REQ信令后不提高发射功率的次数；若所述次数满足预设数量条件，向所述耳机直接发送最高功率指令。在本申请的另一些实施例中，当电子设备接收耳机发送的LL-POWER-CONTROL-REQ信令后确定与耳机的通信质量满足所述预设通信阈值时，可以直接向所述耳机直接发送最高功率指令。
在本申请的一些实施例中，执行图5中502，确定与耳机的通信质量是否满足所述预设通信阈值之后，电子设备可以统计拒绝信令的发送次数；若所述发送次数满足预设数量条件，向所述耳机发送提高信令或最高功率信令。可以理解的是，在本实施例中，若所述发送次数满足预设数量条件向所述耳机发送提高信令后，统计发送提高信令的次数；若向耳机发送提高信令的次数大于预设次数，向耳机发送最高功率信令。
在本申请的一些实施例中，若向耳机发送最高功率信令后，可以按照预设的时间间隔，确定与耳机的通信质量是否满足预设通信阈值。若确定与耳机的通信质量不满足预设通信阈值，主动提高发射功率。若确定与耳机的通信质量满足预设通信阈值，不做任何处理，流程结束。预设的时间间隔可以根据实际情况进行设置，在此不做任何限定。通过该方法，可以避免电子设备当前发射功率不是最高发射功率却向耳机通知当前发射功率为最高发射功率时执行上述方法后，当电子设备的当前发射功率不能满足与耳机的正常通信时，由于电子设备不会主动提高发射功率而导致电子设备与耳机之间的传输效率低的情况发生，提高了发射功率调节的准确率。
可以理解的是，电子设备主动提高发射功率后可以通知耳机，也可以不通知耳机。例如，电子设备可以通过LL-POWER-CONTROL-IND信令，通知耳机已提高发射功率，如功率提升信令。如表3所示，LL-POWER-CONTROL-IND信令中可以包括六个控制参数(ControlData，CtrData)：最小值(Min)；最大值(Max)；保留位(Reserved for future use，RFU)；差值(Delta)、发射功率(TxPower)，物理信道(physical，PHY)。表3中每个控制参数的具体含义可以参见对表1和表2中相关控制参数的介绍，在此不再赘述。

例如，电子设备主动提高发射功率(提高前发射功率为power lever7，主动提高后发射功率为power lever8)后，向耳机发送LL-POWER-CONTROL-IND(Max 0，Delta 1，Txpower 8)信令，告知耳机提高了1db的发射功率，当前电子设备的发射功率为power lever8对应的功率，且当前电子的发射功率不为最大发射功率。可以理解的是，耳机接收到LL-POWER-CONTROL-IND信令，确定电子设备当前不是最高发射功率时，会继续向电子设备请求提高发射功率，此时可以按照图5所示的方法以及与图5相关的实施例中的方法对当前状况进行处理，如对耳机不合理的发射功率提高请求进行拒绝或者耳机提出不合理发射功率请求时，对耳机发送提高信令或最高功率信令。
图5所述的方法以及与图5相关的实施例中的方法的一些具体实施方式，可以参见对图3所述的方法以及与图3相关的实施例的相关描述，在此不做赘述。
