协商速率：协商速率指AP与电子设备之间，综合无线干扰、噪声以及时延等因素进行考虑，最终协定出的一个最大收发数据包的通信速率，协商速率用来保证空口数据传输的可靠性。
下面将结合附图对本申请的实施例进行介绍。
请参阅图2，本申请提供的一种功率调整方法，应用于电子设备，所述方法包括：
S110：获取目标信号强度，所述目标信号强度为所述电子设备所接收到的无线信号的强度，所述无线信号由网络接入设备发送。
其中，作为一种方式，电子设备可以通过RSSI(Received Signal Strength Indication，接收信号强度指示)获取得到目标信号强度。可选的，电子设备可以直接将根据网络接入设备发射的无线信号所计算得到的RSSI作为目标信号强度。
可选的，无线信号可以是Wi-Fi(Wireless Fidelity，无线保真)信号，网络接入设备可以是AP(如：路由器等)。
作为一种方式，电子设备可以从电子设备中的网络模块获取目标信号强度。可选的，电子设备可以周期性地获取目标信号强度。
在本申请实施例中，电子设备可以获取指定时间段内网络接入设备生成的多个目标信号强度。示例性的，指定时间段可以为1分钟，电子设备可以每1秒钟获取一次目标信号强度，此时，电子设备可以设置一个值为60的计数器，每隔1秒钟就对计数器的值减1，并将目标信号强度存在一个数组中，当计数器的值为0时，则不继续获取目标信号强度，从而获取得到1分钟内的目标信号强度作为多个目标信号强度。
可选的，指定时间段可以是基于电子设备对应的通信环境复杂程度进行确定的。作为一种方式，电子设备可以基于所能搜索到的网络接入设备的数量来确定网络复杂程度。若电子设备所处空间下的网络接入设备数量大于预设值，则可以确定电子设备对应的通信环境复杂，并将指定时间段设置为第一指定时间段；若电子设备所处空间下的网络接入设备数量未超过预设值，则可以确定电子设备对应的通信环境简单，并将指定时间段设置为第二指定时间段，其中第一指定时间段小于第二指定时间段，从而使得在通信环境复杂时，可以增加功率调整的频率，使得电子设备的发射功率可以更快速地适应于复杂的通信环境。示例性的，第一指定时间段可以为1分钟，第二指定时间段可以为5分钟，若确定电子设备对应的通信环境复杂，则可以将指定时间段设置为1分钟，也就是说可以每隔1分钟对发射功率进行调整；若确定电子设备对应的通信环境简单，则可以将指定时间段设置为5分钟，也就是说可以每隔5分钟对发射功率进行调整。
可选的，在本申请实施例中，还可以基于电子设备所处空间下，与电子设备已经连接好的网络接入设备存在相同信号频段的网络接入设备的数量，确定电子设备对应的通信环境复杂程度。若电子设备所处空间下，相同信号频段的网络接入设备数量大于预设值，则可以确定电子设备对应的通信环境复杂。反之，则确定电子设备对应的通信环境简单。其中，相同信号频段的网络接入设备可以理解为所发射的无线信号对应的载波频段与电子设备已经连接好的网络接入设备所发射的无线信号的对应的载波频段相同。
可选的，可以获取指定时间段内生成的预设数量的目标信号强度。其中，当电子设备周期性地获取目标信号强度时，若指定时间段对应的时间长度超过预设值，则可以获取预设数量的目标信号强度，预设数量可以小于或等于在指定时间段内电子设备获取到的目标信号强度的总数量。在这种情况下，可以通过随机采样的方式或者按照预设的采样频率从指定时间段内获取到的所有目标信号强度中获取预设数量的目标信号强度。其中，预设的采样频率可以小于或等于网络接入设备的日志上报频率。
在本申请实施例中，通过获取指定时间段内生成的预设数量的目标信号强度，可以在指定时间段内获取到的目标信号强度较多时，对获取 到的目标信号强度进行进一步地筛选，简化数据，提高了后续计算效率。
S120：若基于所述目标信号强度确定所述电子设备处于通信稳定状态，获取所述电子设备当前协商速率以及降低所述电子设备的发射功率，所述当前协商速率表征所述电子设备与所述网络接入设备当前所使用的通信速率。

其中，RSSI可以为目标信号强度，n可以表示衰减因子，A可以表示发射端和接收端相隔1米时的信号强度，n和A可以是经过多次试验得到的经验值。
作为一种方式，可以基于指定时间段内的多个目标信号强度确定电子设备与网络接入设备之间距离是否相对稳定，进而可以确定电子设备是否处于通信稳定状态。
可选的，电子设备可以获取指定时间段内的多个目标信号强度对应的最大目标信号强度和最小目标信号强度，若最大目标信号强度和最小目标信号强度的差值小于预设差值，则确定电子设备处于通信稳定状态。其中，预设差值可以是根据多次试验得到的经验值。示例性的，指定时间段内的多个目标信号强度可以包括：x1、x2、x3...xn，最大目标信号强度可以为x3，最小目标信号强度可以为x1，最大目标信号强度和最小目标信号强度的差值可以为A(x3-x1)，预设差值可以为B，若A<B，则可以确定电子设备处于通信稳定状态；若A≥B，则可以确定电子设备处于通信不稳定状态。
可选的，电子设备可以获取指定时间段内的多个目标信号强度对应的方差，若方差小于预设方差，确定电子设备处于通信稳定状态。其中，预设方差可以是根据多次试验得到的经验值。示例性的，指定时间段内的多个目标信号强度可以包括：x1、x2、x3...xn，多个目标信号强度对应的方差可以为C，预设方差可以为D，若C<D，则可以确定电子设备处于通信稳定状态；若C≥D，则可以确定电子设备处于通信不稳定状态。
作为一种方式，若基于目标信号强度确定电子设备处于通信稳定状 态，电子设备可以与网络接入设备进行通信速率的协商，并将协商好的通信速率作为当前协商速率，并将该当前协商速率作为电子设备当前协商速率，并降低电子设备的发射功率。其中，电子设备的发射功率可以是指电子设备的功率放大器(Power Amplifier，PA)的发射功率。
在本申请实施例中，若基于目标信号强度确定电子设备处于通信不稳定状态，电子设备可以将当前获取到的目标信号强度删除，并重新执行步骤S110以获取新的目标信号强度。
S130：获取参考协商速率，所述参考协商速率为所述电子设备降低发射功率后与所述网络接入设备之间的协商速率。
作为一种方式，电子设备在降低PA的发射功率后，可以再次与网络接入设备进行通信速率的协商，并将协商好的通信速率作为参考协商速率。
S140：若所述参考协商速率与所述当前协商速率相同，控制所述电子设备的发射功率至高为当前的发射功率。
其中，当前的发射功率可以指步骤S120中电子设备执行了降低发射功率操作后的发射功率。
作为一种方式可以将基于步骤S130得到的参考协商速率与基于步骤S120得到的当前协商速率进行比较，若参考协商速率与当前协商速率相同，控制电子设备的发射功率至高为当前的发射功率。
本实施例提供的一种功率调整方法，在获取到表征所述电子设备所接收到的由网络接入设备发送的无线信号的强度的目标强度后，若基于所述目标信号强度确定所述电子设备处于通信稳定状态，获取表征所述电子设备与所述网络接入设备当前所使用的通信速率的当前协商速率以及降低所述电子设备的发射功率，获取表征所述电子设备降低发射功率后与所述网络接入设备之间的协商速率的参考协商速率，若所述参考协商速率与所述当前协商速率相同，控制所述电子设备的发射功率至高为当前的发射功率。从而通过上述方式使得在确定电子设备处于通信稳定状态的情况下，可以获取当前协商速率并尝试降低电子设备的发射功率，进而在尝试降低发射功率之后，确定与网络接入设备之间的通信速率依然为在降低发射功率之前的当前协商速率的情况下，控制所述电子设备的发射功率至高为当前的发射功率，进而实现了在不降低通信速率的情况下，降低了电子设备的发射功率，以实现降低电子设备的功耗。
请参阅图3，本申请提供的一种功率调整方法，应用于电子设备，所述方法包括：
S210：获取目标信号强度，所述目标信号强度为所述电子设备所接收到的无线信号的强度，所述无线信号由网络接入设备发送。
作为一种方式，电子设备可以实时获取目标信号强度。
S220：进入当次的发射功率调整过程，并获取所述电子设备当前协商速率以及降低所述电子设备的发射功率。
在本申请实施例中，为了在保持协商速率不变的情况下，尽可能地降低电子设备的功耗，可以尝试多次基于功率降低幅度对电子设备的发射功率进行降低。
在本申请实施例中，在降低电子设备的发射功率时的降低幅度可以有多种的确定方式。
作为一种方式，降低幅度可以由开发人员默认配置。
作为另外一种方式，可以基于电子设备与网络接入设备之间的距离确定功率降低幅度，并基于功率降低幅度对电子设备的发射功率进行降低。其中，电子设备与网络接入设备之间的距离越近，功率降低幅度越大。
可选的，可以将电子设备与网络接入设备之间的距离划分为多个距离范围，每个距离范围对应于一个功率降低幅度。并且，每个距离范围的距离长度可以不同，可以基于当前距离范围内协商速率对发射功率的变化的敏感程度确定距离长度，敏感程度越高对应的距离长度越小。示例性的，网络接入设备信号覆盖的最大距离可以为10米，可以将该距离划分为6个距离范围：0米～1米、1米～3米、3米～6米、6米～8米、8米～9米、9米～10米，上述6个距离范围对应的功率降低幅度可以为：4dBm、3dBm、2dBm、1.5dBm、1dBm、0.5dBm。
在本申请实施例中，通过基于电子设备与网络接入设备之间的距离确定功率降低幅度的方式，可以提高本申请提出的功率调整方法的智能化程度，使得在距离较近时，可以快速降低发射功率；在距离较远时，可以对发射功率进行精细化调整，尽可能地降低功率。
S230：获取参考协商速率，所述参考协商速率为所述电子设备降低发射功率后与所述网络接入设备之间的协商速率。
S240：若所述参考协商速率与当次的发射功率调整过程的当前协商速率相同，进入下一次的发射功率调整过程。
作为一种方式，若参考协商速率与当次的发射功率调整过程的当前协商速率相同，则可以将参考协商速率作为下一次的发射功率调整过程的当前速率，从步骤S220开始进入下一次的发射功率调整过程。
S250：若所述参考协商速率小于所述当前协商速率，增大所述电子设备的发射功率。
作为一种方式，若参考协商速率小于当次的发射功率调整过程的当前协商速率，则可以基于功率增大幅度对电子设备的发射功率进行增大。其中，功率增大幅度与步骤S220的功率降低幅度相等。
本实施例提供的一种功率调整方法，从而通过上述方式使得在确定电子设备处于通信稳定状态的情况下，可以获取当前协商速率并尝试降低电子设备的发射功率，进而在尝试降低发射功率之后，确定与网络接入设备之间的通信速率依然为在降低发射功率之前的当前协商速率的情况下，控制所述电子设备的发射功率至高为当前的发射功率，进而实现了在不降低通信速率的情况下，降低了电子设备的发射功率，以实现降低电子设备的功耗。并且，在本实施例中，电子设备可以实时获取目标信号强度，并在电子设备处于通信稳定状态的情况下，实时对发射功率进行动态调整，使得电子设备在协商速率不变的情况下可以尽可能地降低发射功率，从而降低了电子设备的功耗。
为了更好地理解本申请所有实施例的方案，下面对本申请的功率调整方法的一种业务流程进行介绍。
请参阅图4，电子设备可以获取指定时间段内的多个目标信号强度，若基于多个信号强度确定电子设备处于通信不稳定状态，则可以将获取到的多个目标信号强度清除并重新获取指定时间段内的多个目标信号强度。若基于多个信号强度确定电子设备处于通信稳定状态，则先可以获取电子设备当前协商速率，并将当前协商速率记为rate0；再基于功率降低幅度对电子设备的发射功率进行降低，并获取发射功率降低后的参考协商速率rate1。
在获取到rate1和rate0后，可以比较rate1是否与rate0相等，若相等，表明在发射功率降低后，协商速率还可以维持不变，也就是说电子设备与网络接入设备之间的数据传输过程不会受到影响，表明电子设备的发射功率可能还存在下降的空间，为了尽可能地减少电子设备的功耗，则可以再次尝试基于功率降低幅度对电子设备的发射功率进行降低；若 不相等(rate1<rate0)，表明在发射功率降低后，协商速率也降低了，协商速率降低可能会导致电子设备与网络接入设备之间的数据传输速率降低甚至无法进行数据传输，表明电子设备的发射功率可能已经降低到低于当前协商速率(rate0)下的极限值，因此可以基于功率增大幅度对电子设备的发射功率进行增大，其中，功率增大幅度与功率降低幅度相等，以便将电子设备的发射功率恢复至当前协商速率(rate0)下的极限值。
其中，可选的，每次在进行发射功率降低前后的协商速率的比较时，可以将当次发射功率降低后的协商速率与rate0进行比较，还可以是与上次比较过程中的rate1进行比较。
示例性的，在基于多个信号强度确定电子设备处于通信稳定状态的情况下，电子设备当前协商速率(rate0)可以为16Mbps，当前协商速率对应的电子设备的最低发射功率可以为18dBm，当前协商速率(rate0)对应的当前发射功率可以为20dBm，功率降低幅度和功率增大幅度可以为1dBm，可以先基于功率降低幅度将发射功率降为19dBm，并获取到参考协商速率(rate1)为16Mbps；则可以继续将发射功率降为18dBm，并获取到此时的参考协商速率(rate1)仍为16Mbps；则可以继续将发射功率降为18dBm，并获取到此时的参考协商速率(rate1)仍为16Mbps；则可以继续将发射功率降为17dBm，并获取到此时的参考协商速率(rate1)开始小于16Mbps，表明电子设备的发射功率下降过多，则可以基于功率增大幅度将发射功率升回18dBm，以将电子设备的协商速率保持在16Mbps。从图5可知，当电子设备的发射功率在19dBm以上时候，每降低1dBm的发射功率，电流就可以降低15mA，对于2*2MIMO(Multiple Input Multiple Output，多进多出)电子设备来说，1dBm的发射功率就可以减小30mA的整机电流，从而降低功耗、节省电量。
