具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例描述的网络架构以及业务场景是为了更加清楚地说明本申请实施例的技术方案，并不构成对本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
请参考图1，其示出了本申请一个实施例提供的网络架构的示意图。该网络架构可以包括：终端10和基站20。
终端10的数量通常为多个，每一个基站20所管理的小区内可以分布一个或多个终端10。 终端10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)，终端设备(terminal device)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。
基站20是一种部署在接入网中用以为终端20提供无线通信功能的装置。基站20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，具备基站功能的设备的名称可能会有所不同，例如在第五代移动通信新空口(5th-Generation New Radio，5G NR)系统中，称为gNodeB或者gNB。随着通信技术的演进，“基站”这一名称可能会变化。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基站。
本公开实施例中的“5G NR系统”也可以称为5G系统或者NR系统，但本领域技术人员可以理解其含义。本公开实施例描述的技术方案可以适用于5G NR系统，也可以适用于5G NR系统后续的演进系统。
SAR指标是终端在6GHz以下频段的通信中在一段时间内的平均测量值。通常来说，SAR值与发射功率以及发射时间成正相关，也就是说，终端的发射功率越高，SAR值也越高，终端的上行发射时间越长，SAR值也越高。
为了满足SAR指标，在一种方案中，终端会采用传感器(比如距离传感器)等来探知终端与人体的距离，并在探测到终端靠近人体时进行功率回退，以降低发射功率，规避SAR值超标。然而，由于用户在使用终端时，很多情况下会将终端靠近人体，因此，该方案虽然能够有效解决SAR值超标的问题，但是很多时间下需要以低发射功率进行上行发送，从而导致发射功率的损失较为严重，从而严重影响上行传输效果。
而在另外一种方案中，在独立组网NR(NR Standalone，NR SA)以及4G无线接入网与5G NR的双连接(Evolved-Universal Telecommunication Radio Access Terrestrial Radio Access-NR Dual Connection，EN-DC)等场景下，终端向基站上报给其在某个频段下以最大发射功率进行上行发送时，在满足SAR要求的情况下所能支持的最大上行时间占比，比如，在NR SA高功率UE(High Power UE，HPUE)中，对6GHz以下频段上定义了maxULdutycycle能力，而在非独立组网(Non-Standalone，NSA)HPUE中定义了maxULdutycycle-EN-DC能力等。当终端实际的上行时间占比超过该最大上行时间占比后，终端以3dBm功率等级回退(6GHz以下频段)的方式来减少SAR值。
然而，上述方案中终端上报给基站的能力信息为一个仅对应终端的最大发射功率的最大上行时间占比支持能力。当终端的发射功率低于最大发射功率时，终端潜在的可以在满足SAR的情况下，接受更高的上行时间占比的调度。而上述方案中的处理方式是只要终端实际的上行时间占比高于maxULdutycycle，则进行3dBm功率等级回退，限定了终端的发射功率能力。
比如，请参考图2，其示例性的示出了一种回退前后的发射功率与行时隙占比之间的对应关系图。
如图2所示，对于6GHz以下频段，终端在发射功率P1(如26dBm)时对应的最大上行时间占比为Dutycycle1，在发射功率为23dBm时对应的最大上行占比能力为100％。
在某一时刻，终端以上述P1为发射功率上限进行上行数据发送，也就是说，终端在发送上行数据时，将控制自身的发射功率不超过P1；在以P1为发射功率上限进行上行数据发送时，终端还可以获取实际的上行时间占比，并将实际的上行时间占比与Dutycycle1进行比较，当实际的上行时间占比超过了Dutycycle1时，终端将发射功率上限直接调整为可以支持100％的上行时间占比的P2(即较低的23dBm)，并在后续发送上行数据时，以P2为发射功率上限进行上行数据发送。
在上述过程中，当终端的实际的上行时间占比超出Dutycycle1时，终端会存在一个3dBm的发射功率上限的跳变，同时最大上行时间占比也存在一个从Dutycycle1到100％的跳变，这就导致终端的发射功率上限收到较大的限制，从而影响终端的上行数据传输效果。
而本申请后续实施例提出了一种在满足SAR要求的情况下，根据终端的实际的上行时间占比，对终端的发射功率上限进行非线性调节的方案，可以在终端的实际的上行时间占比超出Dutycycle1但是不足100％时，适度的调节发射功率上限，避免过于限制终端的发射功率，从而提高终端的上行数据传输效果。
下面，将结合几个示例性实施例，对本申请技术方案进行介绍说明。
请参考图3，其示出了本申请一个实施例提供的发射功率调整的方法的流程图，该方法可应用于图1所示的网络架构的终端中，该方法可以包括如下几个步骤：
步骤301，获取实际的上行时间占比。
其中，该实际的上行时间占比是终端在当前时刻之前的预定时间长度内实际进行上行发送的时间占比。
上述的上行时间占比是指基站调度终端进行上行发送后，终端根据基站的调度实际进行上行发送的时间占总时间的比例。
可选的，上述实际的上行时间占比，可以是在当前时刻之前的预设时间段内，终端实际进行上行发送的时间占比。比如，上述预设时间段内的实际的上行时间占比，是指终端根据基站的调度信息在预设时间段内上行发送的时间，占预设时间段的总时间的比例。
在本申请实施例中，终端在与基站进行数据传输的过程中，可以统计当前时刻之前的预设时间段内的实际的上行时间占比。
步骤302，将该终端的发射功率上限由第一发射功率上限调整为第二发射功率上限；该第二发射功率上限基于该第一发射功率上限、该实际的上行时间占比和该第一发射功率上限对应的最大上行时间占比确定。
在本申请实施例中，终端的发射功率上限，是指终端在进行上行发送时所需要遵循的最大发射功率。也就是说，终端在进行上行发送时，需要控制其发射功率不超过当前设置的发射功率上限。
在本申请实施例中，终端可以根据当前时刻之前的实际的上行时间占比，比如上述预设时间段内的实际的上行时间占比，对发射功率上限进行调节；也就是说，不同的实际的上行时间占比，可以对应终端不同的发射功率上限。
可选的，终端的发射功率上限随着实际的上行时间占比发生变化的规律是非线性的。
在本申请实施例中，在当前时刻之后，终端继续进行上行数据发送时，将控制上行数据发送时的发射功率不超过上述第二发射功率上限，直至发生功率上限再次更新。
综上所述，本申请实施例所示的方案，通过获取当前时刻之前终端的实际的上行时间占比；根据实际的上行时间占比、终端的第一发射功率上限和第一发射功率上限对应的最大上行时间占比确定第二发射功率上限，并将终端的发射功率上限由第一发射功率上限调整为第二发射功率上限；在上述方案中，终端可以对应实际的上行时间占比，对发射功率上限进行调整，也就是说，终端能够按照实际的上行时间占比的值，对发射功率上限进行适度的调整，相对于直接进行大幅度的功率回退的调整方式，本申请所示的方案能够避免过于限制终端的发射功率，从而提高终端的上行数据传输效果。
请参考图4，其示出了本申请一个实施例提供的发射功率调整的方法的流程图，该方法可应用于图1所示的网络架构的基站中，该方法可以包括如下几个步骤：
步骤401，获取终端的实际的上行时间占比。
其中，该实际的上行时间占比是该终端在当前时刻之前的预定时间长度内实际进行上行发送的时间占比。
在本申请实施例中，终端与基站进行数据传输时，其上行发射和下行接收的时间可以由基站进行实时调度或者预调度。其中，基站对终端的行发射和下行接收的时间进行调度的相关信息即可以称为上述的上下行时间配置信息。
比如，基站可以在与终端进行数据通信时，实时的通过上下行时间配置信息，来调度终端后续的上行发射时间和下行接收时间，终端根据该上下行时间配置信息，在上行发射时间执行上行数据发送，并在下行接收时间执行下行数据接收。
或者，基站也可以在与终端进行数据通信之前，预先通过上下行时间配置信息，来调度终端后续可以进行上行发射的上行时间区间，以及可以进行下行接收的下行时间区间，后续需要上行发射时，终端在上行时间区间内选择合适的时机进行发送，当有下行接收需求时，终端可以在下行时间区间内进行监听，并在监听到的下行数据时进行下行接收。
基站在与终端进行数据传输的过程中，可以记录终端上行发送的时间，统计并获取终端的实际的上行时间占比。比如，基站可以统计终端在当前时刻之前的预设时间段内的上行时间占比，即终端在预设时间段内实际进行上行发送的时间，占预设时间段的总时间的比例。
步骤402，将该终端的发射功率上限由第一发射功率上限调整为第二发射功率上限，该第二发射功率上限基于该第一发射功率上限、该实际的上行时间占比和该第一发射功率上限对应的最大上行时间占比确定。
在本申请实施例中，基站可以在该预设时间段之后，将该终端的发射功率上限由第一发射功率上限调整为第二发射功率上限，并接收该终端按照该第二发射功率上限发送的上行数据。
可选的，第二发射功率上限与实际的上行时间占比成非线性的对应关系。
在本申请实施例中，基站侧与终端侧类似，也会根据当前时刻之前的预设时间段内终端的实际的上行时间占比，按照非线性的对应规则，确定终端更新后的发射功率上限(即上述第二发射功率上限)，以便后续接收该终端按照该第二发射功率上限发送的上行数据。
综上所述，本申请实施例所示的方案，基站通过获取终端的实际的上行时间占比；根据实际的上行时间占比、终端的第一发射功率上限和第一发射功率上限对应的最大上行时间占比确定第二发射功率上限，并将终端的发射功率上限由第一发射功率上限调整为第二发射功率上限；在上述方案中，基站可以对应终端的实际的上行时间占比确定终端的发射功率上限，也就是说，能够按照实际的上行时间占比的值，对终端的发射功率上限进行适度的调整，相对于直接触发终端进行大幅度的功率回退的调整方式，本申请所示的方案能够避免过于限制终端的发射功率，从而提高终端的上行数据传输效果。
其中，本申请各个实施例所示的方案适用于NR SA、EN-DC、5G NR与4G无线接入网的双连接(NR-Evolved-Universal Telecommunication Radio Access Terrestrial Radio Access Dual Connection，EN-DC)、双链接(Dual-connectivity，DC)、载波聚合(carrier aggregation，CA)、补充的上行链路(supplementary uplink，SUL)等通过上报最大上行占比能力来解决SAR等问题的场景。
请参考图5，其示出了本申请一个实施例提供的发射功率调整的方法的流程图，该方法可应用于图1所示的网络架构中，由图1中的终端和基站交互执行，该方法可以包括如下几个步骤：
步骤501，终端向基站上报终端能力信息，基站接收该终端能力信息。
其中，所述终端能力信息用于指示所述终端具有根据实际的上行时间占比对终端的发射功率上限进行调整的能力。
在本申请实施例中，终端在成功接入基站时，可以向基站上报其终端能力信息，以通知基站其具有根据实际的上行时间占比对自身的发射功率上限进行调整的能力，以便基站后续在对终端进行上下行调度时，可以基于终端能力信息进行上下行调度。
可选的，上述终端向基站上报的终端能力信息，可以触发基站执行后续的步骤502以及步骤502之后的步骤。
可选的，如果终端没有向基站上报该终端能力信息，或者，终端向基站上报其不具有根据实际的上行时间占比对自身的发射功率上限进行调整的能力，则基站可以不执行后续步骤 502。
步骤502，基站获取终端对应的上行及下行业务的业务需求，根据业务需求获取调度的上行时间占比。
其中，基站可以响应于终端上报过该终端能力信息，执行获取终端对应的上行及下行业务的业务需求的步骤。
可选的，上述业务需求可以包括功率需求以及时延需求中的至少一种。
其中，功率需求用于指示传输相应的上行或下行业务所需要的发射功率；时延需求用于指示传输相应的上行或下行业务所需要的传输时延。
在本申请实施例中，基站可以根据终端对应的上行及下行业务的业务需求，确定对应该上行及下行业务，将要为终端调度的上行时间占比。
比如，当上述业务需求包括功率需求时，假设终端的上行或下行业务所需要的功率需求较高，比如，需要终端以较大的发射功率进行上行发送，此时，基站可以根据功率需求确定为终端调度的，一个较小的上行时间占比，这样终端在后续进行功率调整时，可以在满足SAR要求的情况下，尽可能的提高发射功率上限，以满足上行及下行业务的功率需求。
或者，假设终端的上行或下行业务所需要的功率需求较低，比如，只需要终端以较小的发射功率进行上行发送即可，此时，基站可以根据功率需求确定为终端调度的，一个较大的上行时间占比，这样终端后续进行功率调整时，可以在满足SAR要求的情况下，降低发射功率上限，以满足较大的上行时间占比，从而提高上行传输效率。
在比如，当上述业务需求包括时延需求时，假设终端的上行或下行业务所需要的时延需求较高，比如，需要终端与基站之间以较小的时延进行传输，此时，基站可以根据时延需求确定为终端调度的，一个较大的上行时间占比，这样终端在后续进行功率调整时，可以在满足SAR要求的情况下，降低发射功率上限，以满足较大的上行时间占比，从而提高上行传输效率，进而降低终端与基站之间的上行传输时延。
或者，假设终端的上行或下行业务所需要的时延需求较低，比如，可以允许终端与基站之间存在较大的上行时延，此时，基站可以根据功率需求确定为终端调度的，一个较小的上行时间占比，这样终端后续进行功率调整时，可以在满足SAR要求的情况下，尽可能的提高发射功率上限，以提高终端的上行传输效果。
步骤503，基站根据调度的上行时间占比生成上下行时间配置信息。
在本申请实施例中，基站后续调度终端在预设时间段内的上下行时域资源时，可以按照上述调度的上行时间占比生成上下行时间配置信息。也就是说，在上述上下行时间配置信息中，终端在预设时间段内的上行时间，占预设时间段内的总时间的比值为上述调度的上行时间占比。
步骤504，基站向终端下发上下行时间配置信息，相应的，终端接收该上下行时间配置信息。
其中，该上下行时间配置信息用于指示该终端的上行发射及下行接收的时间配置。比如，该上下行时间配置信息可以指示该终端在预设时间段内的上行发射及下行接收的时间配置。
在本申请实施例中，在基站对终端的上下行资源进行动态调度的情况下，基站可以将生成的上述上下行时间配置信息下发给终端，相应的，终端可以接收基站下发的该上下行时间配置信息。
步骤505，终端与基站根据上述上下行时间配置信息进行上下行数据传输。
在本申请实施例中，终端接收到上述的上下行时间配置信息后，即可以根据上下行时间配置信息所配置的上行时间和下行时间，与基站进行数据传输。
例如，终端在上述上下行时间配置信息所配置的上行时间内，向基站进行上行数据发送；以及，终端在在上述上下行时间配置信息所配置的下行时间内，接收基站发送的下行数据。
步骤506，终端获取实际的上行时间占比。
其中，该实际的上行时间占比是终端在当前时刻之前的预定时间长度内实际进行上行发 送的时间占比。
可选的，终端可以获取预设时间段，实际的上行时间占比。
在本申请实施例中，上述预设时间段是由基站和终端所共知的时间段。
其中，该预设时间段可以是预先定义的时间段。例如，可以在终端以及基站中分别预先定义，从终端接入基站开始，每固定时长的时间段作为一个预设时间段。
或者，上述预设时间段也可以由基站为终端配置，比如，基站可以向终端下发预设时间段配置信息，以指示上述预设时间段的起始点和结束点。
其中，上述预设时间段由基站为终端配置时，基站可以通过半静态或者动态的方式为终端配置预设时间段。
例如，在半静态配置的情况下，终端成功接入基站时，基站可以向终端发送预设时间段配置表，该预设时间段配置表中可以包含多种时间段长度，在基站与终端进行数据传输的过程中，基站可以向终端发送时间段长度指示信息，终端可以根据该时间段长度指示信息所在信道/信号的时域位置，或者，根据其它指定的信道/信号的时域位置，确定预设时间段的起始点，并根据该时间段长度指示信息从预设时间段配置表中确定预设时间段的时长，根据预设时间段的起始点和预设时间段的时长确定上述预设时间段。
或者，在动态配置的情况下，在基站与终端进行数据传输的过程中，基站可以向终端发送时间段长度指示信息，该时间段长度指示信息可以直接包含预设时间段的时长；终端可以根据该时间段长度指示信息所在信道/信号的时域位置，或者，根据其它指定的信道/信号的时域位置，确定预设时间段的起始点，并根据该时间段长度指示信息中包含的预设时间段的时长，以及预设时间段的起始点确定上述预设时间段。
在本申请实施例中，终端在确定出上述预设时间段之后，即可以统计得到上述预设时间段内的实际的上行时间占比。
步骤507，终端获取第一发射功率上限对应的最大上行时间占比。
其中，上述第一发射功率上限，可以是终端在当前时刻之间进行上行发送所使用的发射功率上限。
在一种可能的实现方式中，上述第一发射功率上限，可以是终端在上述预设时间段内进行上行数据发送时使用的发射功率上限。或者说，上述第一发射功率上限，是终端按照上述的上下行时间配置信息进行上行数据发送时使用的发射功率上限。
在本申请实施例中，终端可以根据第一发射功率上限的值，确定出终端在第一发射功率上限下对应的最大上行时间占比，其中，该最大上行时间占比，是指终端的发射功率为上述第一发射功率上限时，终端满足SAR要求的上行时间占比的最大值。
可选的，终端中可以预先设置各个发射功率上限分别对应的最大上行时间占比，终端可以根据第一发射功率上限，查询对应的最大上行时间占比。
或者，终端也可以根据预设的换算关系(比如预设的换算公式)，根据第一发射功率上限计算得到对应的最大上行时间占比。
步骤508，终端根据该实际的上行时间占比和该最大上行时间占比，确定功率调整值。
可选的，若该实际的上行时间占比小于该最大上行时间占比，则对第一比值进行对数函数处理，得到该功率调整值；该第一比值是该最大上行时间占比与该实际的上行时间占比之间的比值。
其中，上述最大上行时间占比与该实际的上行时间占比之间的比值(即第一比值)，是指以最大上行时间占比为分子，以实际的上行时间占比为分母的比值。
可选的，若该实际的上行时间占比大于该最大上行时间占比，则对第二比值进行对数函数处理，得到该功率调整值；该第二比值是该实际的上行时间占比与该最大上行时间占比之间的比值。
其中，上述实际的上行时间占比与该最大上行时间占比之间的比值(即第二比值)，是指以实际的上行时间占比为分子，以最大上行时间占比为分母的比值。
步骤509，终端基于该第一发射功率上限和该功率调整值，确定该第二发射功率上限。
若该实际的上行时间占比小于该最大上行时间占比，则将该第一发射功率上限与该功率调整值的和确定为该第二发射功率上限。
若该实际的上行时间占比小于该最大上行时间占比，则将该第一发射功率上限与该功率调整值的差确定为该第二发射功率上限。
在本申请实施例中，在基站后续为终端调度的上行时间占比下，更新后的终端按照第二发射功率上限发送上行数据时可以满足电磁波吸收比值SAR要求。
在本申请实施例中，终端可以根据实际的上行时间占比与最大上行时间占比之间的差距，适度的对发射功率上限进行降低或者提升，以在满足SAR要求的情况下，尽可能的兼顾上行时间占比和发射功率。上述获取更新后的发射功率上限的方式可以有提升和降低两种。
第一，提升发射功率上限的情况。
在一种可能的实现方式中，当上述实际的上行时间占比小于最大上行时间占比时，终端可以适当的提高发射功率上限，以在满足SAR要求的情况下，保证终端的发射功率，从而保证上行数据传输效果。此时，终端可以通过以下方式来适度的确定一个相对于第一发射功率上限较高的第二发射功率上限：
响应于该实际的上行时间占比小于该最大上行时间占比，通过对数函数对第一比值进行处理，获得功率增加值(即上述功率调整值)；在该第一发射功率上限的基础上增加该功率增加值，获得该第二发射功率上限。
在上述可能的实现方式中，为了在满足SAR要求的情况下，尽可能的提高终端的发射功率，在本申请实施例中，终端可以通过对最大上行时间占比与该实际的上行时间占比之间的比值进行对数处理，确定功率增加值，并在该第一发射功率上限的基础上，结合功率增加值得到适度提升的上述第二发射功率上限。
例如，上述在该第一发射功率上限的基础上增加该功率增加值，以获得第二发射功率上限的公式可以如下：
P1+10*lg(maxUplinkdutycycle/realUplinkdutycycle)；
其中，realUplinkdutycycle为实际的上行时间占比，maxUplinkdutycycle为最大上行时间占比，P1为第一发射功率上限。通过上述公式，终端以10为底数对最大上行时间占比与该实际的上行时间占比之间的比值求对数值，并在第一发射功率上限P1的基础上增加10倍的对数值得到更新后的发射功率上限，从而实现在满足SAR要求的情况下，适度调整终端的发射功率上限，从而尽可能的提高终端的发射功率上限，从而提高终端的上行传输效果。
第二，降低发射功率上限的情况。
在另一种可能的实现方式中，当上述实际的上行时间占比大于最大上行时间占比时，终端可以适当的降低发射功率上限，以优先保证数据传输速率。此时，终端可以通过以下方式来适度的确定一个相对于预设发射功率上限较低的，更新后的发射功率上限：
响应于该实际的上行时间占比大于该最大上行时间占比，通过对数函数对第二比值进行处理，获得功率降低值；在该第一发射功率上限的基础上减少该功率降低值，获得该第二发射功率上限。
在上述可能的实现方式中，为了在满足SAR要求的情况下，尽可能的保证一个发射功率上限不被过度降低，在本申请实施例中，终端可以通过对实际的上行时间占比与该最大上行时间占比之间的比值进行对数处理，确定功率降低值(即上述功率调整值)，并在该第一发射功率上限的基础上，结合功率降低值得到适度降低的，上述第二发射功率上限。
例如，上述在该预设发射功率上限的基础上减少该功率降低值，以获得更新后的发射功率上限的公式可以如下：
P1-10*lg(realUplinkdutycycle/maxUplinkdutycycle)；
通过上述公式，终端以10为底数对实际的上行时间占比与该最大上行时间占比之间的比值求对数值，并在P1的基础上减去10倍的对数值得到更新后的发射功率上限，从而实现在 满足SAR要求的情况下，适度调整终端的发射功率上限，避免对终端的发射功率过于限制，从而提高终端的上行传输效果。
步骤510，终端将发射功率上限由第一发射功率上限调整为第二发射功率上限。
终端确定出上述第二发射功率上限之后，即可以将当前使用的发射功率上限由第一发射功率调整为第二发射功率上限。
在另一种可能的实现方式中，终端也可以在步骤508中确定功率增加值或者功率降低值，并在步骤510中，通过在预设发射功率上直接加上上述功率增加值或者减去上述功率降低值，从而实现发射功率的调整。
步骤511，基站将终端的发射功率上限由第一发射功率上限调整为第二发射功率上限。
在本申请实施例中，除了终端对自己的发射功率上限进行调整之外，基站侧也会根据当前时刻之前，终端的实际的上行时间占比，将终端的发射功率上限调整为上述第二发射功率上限，以便后续能够更好的接收终端发送的上行数据。
其中，基站将终端的发射功率上限调整为第二发射功率上限时，同样可以根据预设时间段内终端的实际的上行时间占比确定上述第二发射功率上限。
其中，基站根据终端的实际的上行时间占比确定第二发射功率上限的方式，与上述步骤507至步骤508中终端确定第二发射功率上限的方式类似，此处不再赘述。
步骤512，终端按照第二发射功率上限进行后续的上行数据发送，相应的，基站接收该终端按照该第二发射功率上限发送的上行数据。
在本申请实施例中，在上述预设时间段之后，终端可以按照调整后的第二发射功率上限，向基站发送上行数据，也就是说，在预设时间段之后，终端向基站发送上行数据时的发射功率不超过第二发射功率上限；相应的，基站在接收终端发送的上行数据时，可以按照该第二发射功率上限进行接收过程的优化。
可选的，在预设时间段之后，基站在为终端进行上下行调度时，可以根据第二发射功率上限对应的最大上行时间占比，为终端生成上下行时间配置信息并下发给终端，也就是说，基站在预设时间段之后生成的上下行时间配置信息将尽可能使得终端在更新后的发射功率上限的情况下满足SAR要求。本申请实施例通过将终端的实际的上行时间占比与发射功率上限一起进行非线性化处理，则终端在低发射功率时可以调度更高的上行占比，从而提高终端的上行占比。
其中，上述第二发射功率上限对应的最大上行时间占比，可以由终端在获取上述第二发射功率上限之后，根据该第二发射功率上限确定并上报给基站。
或者，上述第二发射功率上限对应的最大上行时间占比，也可以由基站在获取上述第二发射功率上限之后，根据该第二发射功率上限确定并保存。
综上所述，本申请实施例所示的方案，通过获取终端的实际的上行时间占比；根据实际的上行时间占比、终端的第一发射功率上限和第一发射功率上限对应的最大上行时间占比确定第二发射功率上限，并将终端的发射功率上限由第一发射功率上限调整为第二发射功率上限；在上述方案中，终端和基站可以对应终端的实际的上行时间占比，对终端的发射功率上限进行非线性的调整，也就是说，终端和基站能够按照终端的实际的上行时间占比的值，对终端的发射功率上限进行适度的调整，相对于直接进行大幅度的功率回退的调整方式，本申请所示的方案能够避免过于限制终端的发射功率，从而提高终端的上行数据传输效果。
