Description

发射功率的确定方法、装置、设备及存储介质 技术领域
本申请涉及通信技术领域，特别涉及发射功率的确定方法、装置、设备及存储介质。
背景技术
终端在通过发送信号提供业务时，会通过天线对外部进行电磁信号的辐射。在终端的辐射天线靠近人体时，人体将吸收电磁能量，从而对人体造成安全问题。因此，出现了比吸收率(Specific Absorption Rate，SAR)法规，以对终端的发射功率进行限制，进而约束人体吸收的电磁能量。

在本申请使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本申请。在本申请和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也是旨在包括多数形式，除非上下文清楚地表示其它含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。

图1示出了本申请一个示例性实施例提供的通信系统的示意图，该通信系统可以包括位于主小区10的信号覆盖范围内的终端20。
主小区10是终端20所对应的服务小区，主小区10对应有一个网络设备，用于为终端20提供无线通信功能。为方便描述，本申请实施例中，上述为终端20提供无线通信功能的装置统称为网络设备。
示意性的，主小区10的周侧具有一个或多个邻小区，比如第一邻小区31和第二邻小区32。相应的，每个邻小区也对应有一个网络设备。两个邻近的网络设备之间也可以通过有线或者无线的方式进行通信，比如通过X2接口进行通信。在终端20从主小区10的信号覆盖范围之内移动到某一个邻小区的信号覆盖范围之内时，终端20可以在对应的网络设备之间进行切换，也即终端20可以与不同的网络设备建立连接。
网络设备可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备网络设备功能的设备的名称可能会有 所不同，例如在5G NR系统中，称为gNodeB或者gNB。随着通信技术的演进，“网络设备”这一名称可能会变化。
终端20的数量可以是一个或多个。其中，终端20可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)、移动台(Mobile Station，MS)等等。为方便描述，本申请实施例中，上面提到的设备统称为终端20。
参考图1，以终端20沿箭头方向从主小区10向第一邻小区31移动为例。假设主小区10对应的网络设备为第一网络设备，第一邻小区31对应的网络设备为第二网络设备。
终端20在主小区10中时，与第一网络设备建立通信连接；在终端20沿箭头方向移动的过程中，终端20逐渐远离第一网络设备；直至终端20移动到第一邻小区31中，终端20断开与第一网络设备的通信连接，与第二网络设备建立通信连接。
在这一过程中，考虑到比吸收率(Specific Absorption Rate，SAR)法规，终端20需要根据主小区10和第一邻小区31的资源调度类型调整终端20的最大发射功率。目前，尚未有预测终端的最大允许发射功率的机制。
图2示出了本申请一个示例性实施例提供的发射功率的确定方法的流程图，该方法由终端执行，包括如下步骤：
步骤102：根据资源调度指示和调度率预测值，确定终端的最大允许发射功率。
示意性的，资源调度指示和调度率预测值由第一网络设备从第二网络设备处获取，第一网络设备是终端的服务小区所对应的网络设备，第二网络设备是终端的次强小区所对应的网络设备。
其中，终端的服务小区是指终端在当前时刻所对应的小区，终端在当前时刻与第一网络设备建立通信连接；终端的次强小区是终端的邻小区中的一个，也可理解为终端在未来时刻可能进入的小区，终端在当前时刻并未与第二网络设备建立通信连接，可能在未来时刻与第二网络设备建立通信连接。可选的，次强小区是第一网络设备根据终端发送的信号测量数据确定的。比如，终端的次强小区是邻小区中信号强度最强的邻小区。
资源调度指示用于指示次强小区所对应的资源调度类型。其中，资源调度指示所对应的资源调度类型与服务小区所对应的资源调度类型可以是相同的，也可以是不同的。
调度率预测值用于指示终端在接入次强小区时所对应的调度率的预测值， 调度率预测值可由第二网络设备预估得到，根据不同的调度率预测值能够计算得到不同的最大允许发射功率。其中，其数值可能与终端在服务小区时所对应的调度率的数值是相同的，也可以是不同的。
可选的，第二网络设备可根据终端的业务类型、次强小区的空闲资源支持的最大调度率和第二网络设备支持的最大调度率确定调度率预测值。可选的，终端的业务类型由第一网络设备向第二网络设备发送，比如，第一网络设备通过X2接口向第二网络设备发送终端的业务类型。其中，不同的业务类型对应有不同的调度率，比如，语音业务对应的调度率是低于20％。次强小区的空闲资源在不同时刻是随机的，比如，在当前时刻，次强小区中有多个终端需要使用资源，则次强小区的空闲资源相对较少。
以终端的业务类型是语音业务，次强小区对应的资源调度类型是传输时间间隔绑定(Transmission Time Interval-bundling，TTI-bundling)为例。根据业务类型和次强小区对应的资源调度类型，能够确定业务类型对应的理论调度率应当是80％。此时，次强小区的空闲资源较多，所支持的最大调度率能够达到80％；而第二网络设备支持的最大调度率仅为60％。基于此，第二网络设备可将上述三个调度率中的最小值确定为调度率预测值，也即调度率预测值为60％。
根据前述举例，在终端接入次强小区之前，第二网络设备能够预估得到终端的调度率预测值，并将该调度率预测值和资源调度指示经第一网络设备发送给终端，以便于终端确定自身的最大允许发射功率。其中，根据资源调度指示和调度率预测值，终端可确定维持终端原有的最大允许发射功率，或者更新最大允许发射功率。
可选的，在调度率预测值与终端原有的调度率相同的情况下，维持终端原有的最大允许发射功率；在资源调度指示与终端的资源调度类型不同和/或调度率预测值与终端原有的调度率不同的情况下，根据调度率预测值，更新最大允许发射功率。
其中，若调度率预测值与终端原有的调度率相同，则终端可维持原有的最大允许发射功率，以避免终端的瞬时发射功率超过SAR法规所规定的发射功率而导致业务失败。
终端的资源调度类型是指终端在服务小区时的资源调度类型，资源调度指示用于指示终端在次强小区时的资源调度类型，若资源调度指示与终端的资源调度类型不同，则终端在次强小区时的资源调度类型与终端在服务小区时的资源调度类型不一致，由此存在终端原有的调度率与调度率预测值不同的可能性。此时，需要更新终端的最大允许发射功率。
根据上述内容，若资源调度指示与终端的资源调度类型不同，和/或调度率预测值与终端原有的调度率不同，终端可根据调度率预测值更新最大允许发射 功率，以避免终端的瞬时发射功率超过SAR法规所规定的发射功率而导致业务失败。
其中，终端根据调度率预测值更新最大允许发射功率可通过多种方式确定。以终端在第一时刻接入次强小区，T为计算平均SAR值的时间窗口为例，以下给出一种更新最大允许发射功率的实现方式：
第一时刻是T时段内的任意一个时点。比如，第一时刻是T时段内的中间时点，或者是T时段内的倒数第二个时点。根据SAR法规，在T时段内的平均SAR值应当不超过规定数值，平均SAR值由T时段内的所有瞬时发射功率的平均值确定。
应当理解的是，终端在第一时刻之前的发射功率是已知的，终端可根据历史发射记录获取得到。将终端在第一时刻之前的发射功率记为第一发射功率，第一发射功率可以是一个或多个发射功率。
终端在第一时刻之后的发射功率可根据调度率预测值确定。将终端在第一时刻之后的发射功率记为第二发射功率，第二发射功率可以是一个或多个发射功率。
示例性的，以第一时刻是T时段内的中间时点t为例，T时段内的平均SAR值的计算公式如下：
Figure PCTCN2022099552-appb-000001
其中，P average(t)用于指示时间段[t-T/2，t+T/2]的平均发射功率，P(i)用于指示i时刻的发射功率。
根据前述内容，第一发射功率为终端在t-T/2时刻到t-△T时刻的发射功率，△T用于指示抽样时间间隔，该时间段内的发射功率是已知的；第二发射功率为终端在t+△T时刻到t+T/2时刻的发射功率，该时间段内的发射功率是根据调度率预测值确定得到的，且在t+1时刻到t+T/2时刻内的每个时刻的发射功率是相同的。随后，基于上述计算公式，能够计算得到第一时刻t所对应的预测发射功率P(t)。
比如，将P average(t)定义为最大允许峰值功率(Maximum Allowable Peak Power)以进行计算，最大允许峰值功率用于指示运营商规定的T时段内的平均发射功率的上限，可记为P limit。基于上述计算公式，使得P average(t)＝P limit，根据已知的第一发射功率和预测得到的第二发射功率，能够计算得到第一时刻t所对应的预测发射功率P(t)。
在SAR机制中，还规定了终端的最大发射功率，终端的最大发射功率可记为PcMAX。在计算得到预测发射功率P(t)后，还需要将P(t)与PcMAX进行比较，以更新终端的最大允许发射功率。比如，在P(t)≥PcMAX的情况下，将终 端的最大发射功率更新为最大允许发射功率；在P(t)＜PcMAX的情况下，将预设发射功率更新为最大允许发射功率。
应当理解的是，在第一时刻是T时段内的倒数第二个时点的情况下，也可参考前述举例的方式，计算得到第一时刻t所对应的预测发射功率P(t)，进而更新最大允许发射功率，不再赘述。
综上所述，本申请实施例提供的发射功率的确定方法，提供了一种预测终端的最大允许发射功率的机制，根据第一网络设备从第二网络设备处获取到的资源调度指示和调度率预测值，以便于终端在接入次强小区之前能够提前确定终端的最大允许发射功率，从而降低终端的业务受到影响的可能性。
图3示出了本申请一个示例性实施例提供的发射功率的确定方法的流程图，该方法由第一网络设备执行，第一网络设备是终端的服务小区所对应的网络设备。该方法包括如下步骤：
步骤202：接收第二网络设备发送的资源调度指示和调度率预测值。
示意性的，第二网络设备是终端的次强小区所对应的网络设备。
其中，服务小区、次强小区的相关描述可参考前述内容，不再赘述。
可选的，在终端从服务小区的移动过程中，第一网络设备可根据终端发送的信号测量数据确定次强小区，从而确定次强小区对应的第二网络设备。其中，信号测量数据用于指示终端实时测量得到的信号强度，不同的邻小区对应有不同的信号强度。
比如，终端在实时测量得到不同邻小区的信号强度后，可实时更新邻区列表清单。其中，邻区列表清单中包括至少一个邻小区及其对应的信号强度，一个邻小区对应于一个信号强度。随后，终端将邻区列表清单中信号强度最强的邻小区确定为次强小区，从而确定与次强小区对应的第二网络设备。
示意性的，网络设备之间可通过X2接口进行通信连接。比如，通过X2接口，接收第二网络设备发送的资源调度指示和调度率预测值。
其中，资源调度指示用于指示次强小区所对应的资源调度类型；调度率预测值用于指示终端在接入次强小区时所对应的调度率的预测值。
可选的，第二网络设备可根据终端的业务类型、次强小区的空闲资源支持的最大调度率和第二网络设备支持的最大调度率确定调度率预测值。其中，终端的业务类型由第一网络设备向第二网络设备发送。比如，第一网络设备向第二网络设备发送调度率预测信息，调度率预测信息至少携带有终端的业务类型。
资源调度指示、调度率预测值以及调度率预测值确定方式的相关描述可参考前述内容，不再赘述。
步骤204：向终端发送资源调度指示和调度率预测值。
示意性的，资源调度指示和调度率预测值用于确定终端的最大允许发射功率。
第一网络设备在获取到第二网络设备发送的资源调度指示和调度率预测值，将其转发给终端，以便于终端确定自身的最大允许发射功率。其中，根据资源调度指示和调度率预测值，终端可确定维持终端原有的最大允许发射功率，或者更新最大允许发射功率。
可选的，在调度率预测值与终端原有的调度率相同的情况下，维持终端原有的最大允许发射功率；在资源调度指示与终端的资源调度类型不同和/或调度率预测值与终端原有的调度率不同的情况下，根据调度率预测值，更新最大允许发射功率。
其中，若调度率预测值与终端原有的调度率相同，则终端可维持原有的最大允许发射功率，以避免终端的瞬时发射功率超过SAR法规所规定的发射功率而导致业务失败。
若资源调度指示与终端的资源调度类型不同，和/或调度率预测值与终端原有的调度率不同，终端可根据调度率预测值更新最大允许发射功率，以避免终端的瞬时发射功率超过SAR法规所规定的发射功率而导致业务失败。
终端更新最大允许发射功率的相关描述可参考前述内容，不再赘述。
综上所述，本申请实施例提供的发射功率的确定方法，提供了一种预测终端的最大允许发射功率的机制，第一网络设备向终端转发从第二网络设备处获取到的资源调度指示和调度率预测值，以便于终端在接入次强小区之前能够提前确定终端的最大允许发射功率，从而降低终端的业务受到影响的可能性。
图4示出了本申请一个示例性实施例提供的发射功率的确定方法的流程图，该方法由第二网络设备执行，第二网络设备是终端的次强小区所对应的网络设备。该方法包括如下步骤：
步骤302：向第一网络设备发送资源调度指示和调度率预测值。

图5示出了本申请一个示例性实施例提供的发射功率的确定方法的流程图。该方法包括如下步骤：
步骤401：第二网络设备向第一网络设备发送资源调度指示和调度率预测值。
示意性的，第一网络设备是终端的服务小区所对应的网络设备，第二网络设备是终端的次强小区所对应的网络设备。
其中，资源调度指示用于指示次强小区所对应的资源调度类型；调度率预测值用于指示终端在接入次强小区时所对应的调度率的预测值。

终端更新最大允许发射功率的相关描述可参考前述内容，不再赘述。
综上所述，本申请实施例提供的发射功率的确定方法，提供了一种预测终端的最大允许发射功率的机制，根据第一网络设备从第二网络设备处获取到的资源调度指示和调度率预测值，终端在接入次强小区之前能够提前确定终端的最大允许发射功率，从而降低终端的业务受到影响的可能性。
根据前述内容，在获取到资源调度指示和调度率预测值后，终端可确定维持终端原有的最大允许发射功率，或者更新最大允许发射功率。
参考图5，图6示出了本申请一个示例性实施例提供的发射功率的确定方法的流程图，步骤403可实现为步骤4031和步骤4032。步骤4031和步骤4032可择一执行，不能同时执行，具体如下：
步骤4031：在调度率预测值与终端原有的调度率相同的情况下，维持终端原有的最大允许发射功率。
应当理解的是，终端原有的调度率是符合SAR法规的，若调度率预测值与终端原有的调度率相同，则终端可维持原有的最大允许发射功率，以避免终端的瞬时发射功率超过SAR法规所规定的发射功率而导致业务失败。
步骤4032：在资源调度指示与终端的资源调度类型不同和/或调度率预测值与终端原有的调度率不同的情况下，根据调度率预测值，更新最大允许发射功率。
其中，资源调度指示用于指示终端在次强小区时的资源调度类型，终端的资源调度类型是指终端在服务小区时的资源调度类型。
若资源调度指示与终端的资源调度类型不同，则终端在次强小区时的资源调度类型与终端在服务小区时的资源调度类型不一致，由此可能导致终端原有的调度率与调度率预测值是不同的，从而可能导致终端原有的最大允许发射功率不再符合SAR法规。比如，终端的资源调度类型是半静态调度或者TTI-bundling，资源调度指示对应的资源调度类型是simultaneous transmission of PUSCH and PUCCH。此时，需要更新终端的最大允许发射功率，以避免终端的瞬时发射功率超过SAR法规所规定的发射功率而导致业务失败。
若调度率预测值与终端原有的调度率不同，则同样存在终端原有的最大允许发射功率不再符合SAR法规的可能性，从而需要更新终端的最大允许发射功率，以避免终端的瞬时发射功率超过SAR法规所规定的发射功率而导致业务失败。
终端根据调度率预测值更新最大允许发射功率可通过多种方式确定。可选的，步骤4032可实现为如下：
在资源调度指示与终端的资源调度类型不同和/或调度率预测值与终端原有的调度率不同的情况下，获取终端在第一时刻之前的第一发射功率；
根据调度率预测值，确定终端在第一时刻之后的第二发射功率；
根据第一发射功率和第二发射功率，确定终端在第一时刻的预测发射功率；
根据预测发射功率和终端的最大发射功率，更新最大允许发射功率，终端的最大发射功率是终端对应的发射功率的上限值。
根据前述内容，根据第一发射功率和第二发射功率来确定终端在第一时刻的预测发射功率，可通过T时段内的平均SAR值的计算公式实现，T为计算平均SAR值的时间窗口。
示意性的，第一时刻是T时段内的任意一个时点。比如，第一时刻是T时段内的中间时点，或者是T时段内的倒数第二个时点。根据SAR法规，在T时段内的平均SAR值应当不超过规定数值，平均SAR值由T时段内的所有瞬时发射功率的平均值确定。
应当理解的是，终端在第一时刻之前的发射功率是已知的，终端可根据历史发射记录获取得到。将终端在第一时刻之前的发射功率记为第一发射功率，第一发射功率可以是一个或多个发射功率。
终端在第一时刻之后的发射功率可根据调度率预测值确定。将终端在第一时刻之后的发射功率记为第二发射功率，第二发射功率可以是一个或多个发射功率。
图7示出了本申请一个示例性实施例提供的发射功率随时间变化的示意图。 其中，PcMAX用于指示终端的最大发射功率；最大允许峰值功率(Maximum Allowable Peak Power)用于指示运营商规定的T时段内的平均发射功率的上限，可记为P limit；终端在T时段内的实际发射功率根据业务类型等影响因素发生变化，也可称之为终端的瞬时功率(instantaneous Power)。
示例性的，以第一时刻是T时段内的中间时点t为例。
参考图7，图8示出了本申请一个示例性实施例提供的计算终端的最大发射功率的示意图，△T用于指示抽样时间间隔，T时段内的抽样次数为N。
其中，T时段内的平均SAR值的计算公式如下：
Figure PCTCN2022099552-appb-000002
其中，P average(t)用于指示时间段[t-T/2，t+T/2]的平均发射功率，P(i)用于指示i时刻的发射功率。
根据前述内容，第一发射功率为终端在t-T/2时刻到t-△T时刻的发射功率，该时间段内的发射功率是已知的；第二发射功率为终端在t+△T时刻到t+T/2时刻的发射功率，该时间段内的发射功率是根据调度率预测值确定得到的，且在t+1时刻到t+T/2时刻内的每个时刻的发射功率是相同的。随后，基于上述计算公式，能够计算得到第一时刻t所对应的预测发射功率P(t)。
比如，将P average(t)定义为最大允许峰值功率，即P average(t)＝P limit，基于上述计算公式，根据已知的第一发射功率和预测得到的第二发射功率，能够计算得到第一时刻t所对应的预测发射功率P(t)。
在SAR机制中，还规定了终端的最大发射功率，终端的最大发射功率可记为PcMAX。在计算得到预测发射功率P(t)后，还需要将P(t)与PcMAX进行比较，以更新终端的最大允许发射功率。
可选的，根据预测发射功率和终端的最大发射功率，更新最大允许发射功率，可实现为如下：

可选的，本申请实施例还给出了根据调度率预测值更新最大允许发射功率的实现方式。其中，根据调度率预测值确定第二发射功率，根据已知的第一发射功率和第二发射功率确定终端在第一时刻的预测发射功率，将其与终端的最大发射功率相比，来确定更新后的最大允许发射功率。基于上述更新方式，终端可根据已知的第一发射功率和预测的第二发射功率来预测更新后的最大允许发射功率，从而使得终端的发射功率能够符合SAR法规，降低终端的业务受到影响的可能性。
根据前述内容，调度率预测值可由第二网络设备根据终端的业务类型、次强小区的空闲资源支持的最大调度率、第二网络设备支持的最大调度率确定。可选的，终端的业务类型由第一网络设备向第二网络设备发送。
以下将对调度率预测值的确定展开描述：
参考图5，图9示出了本申请一个示例性实施例提供的发射功率的确定方法的流程图。在步骤401之前，该方法还包括步骤404和步骤405，具体如下：
步骤404：第一网络设备向第二网络设备发送调度率预测信息。
示意性的，调度率预测信息中至少携带有终端的业务类型，调度率预测信息用于第二网络设备确定调度率预测值。
一个业务类型对应有一个调度率，根据终端的业务类型能够唯一确定一个调度率。参考终端所在的小区的资源调度类型，能够确定终端的业务类型所对应的理论调度率。其中，理论调度率是指在不考虑其他影响因素的情况下，终端在某一时刻下处于对应的服务小区中，根据该服务小区的资源调度类型，终端在该时刻下的业务类型所对应的调度率。
可选的，调度率预测信息中还携带有如下信息中的至少一种：终端的资源调度类型；终端的占空比；终端的RSRP值；终端的次强RSRP值。
其中，占空比用于指示在一个脉冲循环内，终端的通电时间相对于总时间所占的比例，占空比也可理解为终端原有的调度率。
可选的，网络设备之间可通过X2接口进行通信连接。比如，第一网络设备通过X2接口向第二网络设备发送调度率预测信息，调度率预测信息中至少携带有终端的业务类型。
图10示出了本申请一个示例性实施例提供的节点交互的示意图，目标节点能够通过Xn接口向源节点发送交换信息，X2接口是Xn接口中的一种。
示意性的，Xn接口有如下规范(The Xn interface specifications facilitate the following)：
不同厂商提供的NG-RAN节点互联(inter-connection of NG-RAN nodes supplied by different manufacturers)；
支持通过NG接口提供的NG-RAN服务的NG-RAN节点之间的延续(support of continuation between NG-RAN nodes of the NG-RAN services offered via the NG interface)；
分离Xn接口无线电网络功能和传输网络功能，以促进未来技术的引入(separation of Xn interface Radio Network functionality and Transport Network functionality to facilitate introduction of future technology)。
步骤405：第二网络设备根据终端的业务类型、次强小区的空闲资源支持的最大调度率、第二网络设备支持的最大调度率，确定调度率预测值。
根据前述内容，根据终端的业务类型能够唯一确定一个调度率；参考终端所在的小区的资源调度类型，能够确定终端的业务类型所对应的理论调度率。其中，不同的业务类型对应有不同的调度率，比如，语音业务对应的调度率是低于20％；微信语音业务对应的调度率是低于30％。
在获取到第一网络设备发送的调度率预测信息后，第二网络设备能够获取到终端的业务类型；随后，第二网络设备可据此确定调度率预测值。
可选的，步骤405可实现为如下：
根据终端的业务类型和次强小区对应的资源调度类型，确定终端的业务类型对应的理论调度率；
将理论调度率、次强小区的空闲资源支持的最大调度率和第二网络设备支持的最大调度率中的最小值，确定为调度率预测值。
其中，次强小区的空闲资源在不同时刻是随机的，比如，在当前时刻，次强小区中有多个终端需要使用资源，则次强小区的空闲资源相对较少。
比如，终端的业务类型是语音业务，次强小区对应的资源调度类型是TTI-bundling。根据业务类型和次强小区对应的资源调度类型，能够确定业务类型对应的理论调度率应当是80％。此时，次强小区的空闲资源较多，所支持的最大调度率能够达到80％；而第二网络设备支持的最大调度率仅为60％。基于此，第二网络设备可将上述三个调度率中的最小值确定为调度率预测值，也即调度率预测值为60％。
又如，终端的业务类型是微信语音业务，次强小区对应的资源调度类型是半静态调度。根据业务类型和次强小区对应的资源调度类型，能够确定业务类型对应的理论调度率应当是30％。此时，次强小区的空闲资源较少，所支持的最大调度率仅能达到20％；而第二网络设备支持的最大调度率为50％。基于此，第二网络设备可将上述三个调度率中的最小值确定为调度率预测值，也即调度率预测值为20％。
综上所述，本申请实施例提供的发射功率的确定方法中，给出了调度率预测值的确定方式。其中，第二网络设备可根据终端的业务类型、次强小区的空 闲资源支持的最大调度率、第二网络设备支持的最大调度率，来确定调度率预测值，以便于通过第一网络设备发送给终端。
可选的，调度率预测值是终端的业务类型对应的理论调度率、次强小区的空闲资源支持的最大调度率、第二网络设备支持的最大调度率中的最小值，以避免确定的调度率预测值超过次强小区的空闲资源或者第二网络设备支持的最大调度率，进而降低终端的业务受到影响的可能性。
参考图9，图11是本申请一个示例性实施例提供的发射功率的确定方法的流程图，该方法还包括步骤406、步骤407和步骤408，具体如下：
步骤406：在终端的定时提前(Timing Advance，TA)值持续变大的情况下，第一网络设备确定终端远离第一网络设备。
终端的TA值由第一网络设备配置，用于指示终端在上行传输时需要提前的时间量。其中，TA值越大，终端与第一网络设备之间的距离越大，反之终端与第一网络设备之间的距离越小。
根据第一网络设备向终端配置的TA值，第一网络设备能够判断出终端与第一网络设备之间的距离的变化。在终端的TA值持续变大的情况下，第一网络设备能够确定终端正在远离第一网络设备。
在一种可选的实施场景下，第一网络设备在确定终端远离第一网络设备的情况下，向终端发送资源调度指示和调度率预测值，以避免错误更改终端的最大允许发射功率。比如，终端在服务小区中移动，可能会移动到服务小区和次强小区的交叉区域内，但终端始终在该交叉区域内移动，并未向次强小区靠近，第一网络设备可根据终端的TA值确定终端未远离第一网络设备。此时，第一网络设备不向终端发送资源调度指示和调度率预测值，以避免对终端的最大允许发射功率进行错误更改。
可选的，步骤402可实现为如下：
在终端远离第一网络设备，终端的参考信号接收功率(Reference Signal Received Power，RSRP)小于RSRP门限值，且终端的功率余量报告(Power Headroom Report，PHR)小于PHR门限值的情况下，第一网络设备向终端发送资源调度指示和调度率预测值。
其中，终端远离第一网络设备的相关描述可参考前述内容，不再赘述。
终端的RSRP小于RSRP门限值，且终端的PHR小于PHR门限值，用于提高判断终端远离第一网络设备的准确度。其中，RSRP门限值和PHR门限值可根据实际需要进行设置，本申请在此不做限定。
可选的，在终端从服务小区的移动过程中，第一网络设备可根据终端发送的信号测量数据确定次强小区，从而确定次强小区对应的第二网络设备。
步骤407：终端向第一网络设备发送信号测量数据。
示意性的，信号测量数据用于指示终端实时测量得到的信号强度，不同的邻小区对应有不同的信号强度。
比如，终端在实时测量得到不同邻小区的信号强度后，可实时更新邻区列表清单。其中，邻区列表清单中包括至少一个邻小区及其对应的信号强度，一个邻小区对应于一个信号强度。
步骤408：第一网络设备根据信号测量数据确定次强小区。
根据终端发送的信号测量数据，第一网络设备能够获取到实时更新后的邻区列表清单。随后，终端可从邻区列表清单确定出次强小区。比如，第一网络设备将邻区列表清单中信号强度最强的邻小区确定为次强小区，从而确定与次强小区对应的第二网络设备。
综上所述，本申请实施例提供的发射功率的确定方法中，给出了第一网络设备向终端发送资源调度指示和调度率预测值的时机，以提高预测终端的最大允许发射功率的准确性。
可选的，本申请实施例还给出了第一网络设备确定次强小区的实现方式，第一网络设备可通过终端发送的信号测量数据确定次强小区，进而确定次强小区对应的第二网络设备，以便于从第二网络设备处获取到资源调度指示和调度率预测值。
图12示出了本申请一个示例性实施例提供的发射功率的确定方法的流程图，该方法包括如下步骤：
步骤501：终端确定终端的最大发射功率。
在终端的移动过程中，终端需要实时确定自身的最大发射功率，以满足SAR法规，避免业务失败。
以时刻1是历史时刻，时刻2是当前时刻，时刻3是未来时刻为例。根据步骤501，在当前时刻下，终端需要确定时刻2的最大发射功率；当时。其中，终端在时刻2的最大发射功率可以与时刻1的最大发射功率相同，也可以与时刻1的最大发射功率不同。
本申请实施例以预测时刻3的最大发射功率为例。
步骤502：第一网络设备根据TA值确定终端正在远离，且RSRP和PHR低于对应的门限值。
示意性的，终端的TA值用于指示终端在上行传输时需要提前的时间量；TA值越大，终端与第一网络设备之间的距离越大，反之终端与第一网络设备之间的距离越小。RSRP和PHR低于对应的门限值，用于指示终端的RSRP小于RSRP门限值，且终端的PHR小于PHR门限值；RSRP门限值和PHR门限值可 根据实际需要进行限定。
可选的，在终端的TA值持续变大的情况下，第一网络设备确定终端远离第一网络设备。
步骤503：第一网络设备查找终端上报的信号测量数据，以确定次强小区。
示意性的，信号测量数据用于指示终端实时测量得到的信号强度，不同的邻小区对应有不同的信号强度。
比如，终端在实时测量得到不同邻小区的信号强度后，可实时更新邻区列表清单。其中，邻区列表清单中包括至少一个邻小区及其对应的信号强度，一个邻小区对应于一个信号强度。
随后，终端可从邻区列表清单确定出次强小区。比如，第一网络设备将邻区列表清单中信号强度最强的邻小区确定为次强小区，从而确定与次强小区对应的第二网络设备。
步骤504：通过X2接口，第一网络设备向第二网络设备发送调度率预测信息。
示意性的，调度率预测信息中至少携带有终端的业务类型，调度率预测信息用于第二网络设备确定调度率预测值。
可选的，调度率预测信息中还携带有如下信息中的至少一种：终端的资源调度类型；终端的占空比；终端的RSRP值；终端的次强RSRP值。
调度率预测信息和X2接口的相关描述可参考前述内容，不再赘述。
步骤505：第二网络设备确定调度率预测值。
在获取到调度率预测信息后，第二网络设备能够确定终端的业务类型，以确定调度率预测值。
其中，调度率预测值用于指示终端在接入次强小区时所对应的调度率的预测值，调度率预测值可由第二网络设备预估得到，根据不同的调度率预测值能够计算得到不同的最大允许发射功率。其中，其数值可能与终端在服务小区时所对应的调度率的数值是相同的，也可以是不同的。
可选的，调度率预测值由第二网络设备根据终端的业务类型、次强小区的空闲资源支持的最大调度率、第二网络设备支持的最大调度率确定。
可选的，步骤505可实现为如下：
第二网络设备根据终端的业务类型和次强小区对应的资源调度类型，确定终端的业务类型对应的理论调度率；
第二网络设备将理论调度率、次强小区的空闲资源支持的最大调度率和第二网络设备支持的最大调度率中的最小值，确定为调度率预测值。
比如，终端的业务类型是语音业务，次强小区对应的资源调度类型是TTI-bundling。根据业务类型和次强小区对应的资源调度类型，能够确定业务类 型对应的理论调度率应当是80％。此时，次强小区的空闲资源较多，所支持的最大调度率能够达到80％；而第二网络设备支持的最大调度率仅为60％。基于此，第二网络设备可将上述三个调度率中的最小值确定为调度率预测值，也即调度率预测值为60％。
又如，终端的业务类型是微信语音业务，次强小区对应的资源调度类型是半静态调度。根据业务类型和次强小区对应的资源调度类型，能够确定业务类型对应的理论调度率应当是30％。此时，次强小区的空闲资源较少，所支持的最大调度率仅能达到20％；而第二网络设备支持的最大调度率为50％。基于此，第二网络设备可将上述三个调度率中的最小值确定为调度率预测值，也即调度率预测值为20％。
步骤506：第一网络设备向终端转发资源调度指示和调度率预测值。
在确定调度率预测值之后，第二网络设备可通过X2接口将调度率预测值和资源调度指示发送给第一网络设备；随后，第一网络设备向终端转发资源调度指示和调度率预测值。
其中，资源调度指示用于指示次强小区所对应的资源调度类型。其中，资源调度指示所对应的资源调度类型与服务小区所对应的资源调度类型可以是相同的，也可以是不同的。
步骤507：终端判断资源调度类型与调度率预测值是否一致。
终端在获取到资源调度指示和调度率预测值，可根据资源调度指示所指示的资源调度类型与调度率预测值进行判断，以确定维持原有的最大发射功率，或者更新最大发射功率。
其中，资源调度类型与调度率预测值一致，用于指示调度率预测值与终端原有的调度率相同；资源调度类型与调度率预测值不一致，用于指示资源调度指示与终端的资源调度类型不同和/或调度率预测值与终端原有的调度率不同。
以时刻1是历史时刻，时刻2是当前时刻，时刻3是未来时刻为例。
在资源调度类型与调度率预测值一致的情况下，维持原有的最大发射功率，执行步骤501，将时刻3对应的最大发射功率确定为时刻2所对应的最大发射功率。
在资源调度类型与调度率预测值不一致的情况下，执行步骤508，根据调度率预测值，更新最大允许发射功率，将时刻3对应的最大发射功率更新为新的最大发射功率，新的最大发射功率与时刻2所对应的最大发射功率可以相同或不同。
步骤508：终端更新最大发射功率。
在资源调度类型与调度率预测值不一致的情况下，终端根据调度率预测值，更新最大允许发射功率，以避免终端的瞬时发射功率超过SAR法规所规定的发 射功率而导致业务失败。
可选的，步骤508可实现为如下：
终端获取终端在第一时刻之前的第一发射功率；
终端根据调度率预测值，确定终端在第一时刻之后的第二发射功率；
终端根据第一发射功率和第二发射功率，确定终端在第一时刻的预测发射功率；
终端根据预测发射功率和终端的最大发射功率，更新最大允许发射功率，终端的最大发射功率是终端对应的发射功率的上限值。
根据前述内容，根据第一发射功率和第二发射功率来确定终端在第一时刻的预测发射功率，可通过T时段内的平均SAR值的计算公式实现，T为计算平均SAR值的时间窗口。
示意性的，第一时刻是T时段内的任意一个时点。比如，第一时刻是T时段内的中间时点，或者是T时段内的倒数第二个时点。应当理解的是，终端在第一时刻之前的发射功率是已知的，终端可根据历史发射记录获取得到；终端在第一时刻之后的发射功率可根据调度率预测值确定。
示例性的，以第一时刻是T时段内的中间时点t为例，第一时刻t所对应的预测发射功率P(t)的计算过程可参考前述内容，不再赘述。
在计算得到预测发射功率P(t)后，还需要将P(t)与PcMAX进行比较，以更新终端的最大允许发射功率。比如，在P(t)≥PcMAX的情况下，将终端的最大发射功率更新为最大允许发射功率；在P(t)＜PcMAX的情况下，将预设发射功率更新为最大允许发射功率。
综上所述，本申请实施例提供的发射功率的确定方法，提供了一种预测终端的最大允许发射功率的机制，根据第一网络设备从第二网络设备处获取到的资源调度指示和调度率预测值，以便于终端在接入次强小区之前能够提前确定终端的最大允许发射功率，从而降低终端的业务受到影响的可能性。
