具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本公开及其应用或使用的任何限制。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
发明人发现：高功率载波聚合方案即提升上行聚合载波发射功率，可能会导致终端发射功率超过地方法规的电磁能量吸收(Electromagnetic energy absorption)指标要求(或者SAR(Specific Absorption Rate，电磁波吸收比值，或者称为电磁波人体吸收比率)法规要求)。
本公开所要解决的一个技术问题是：如何在提高上行载波聚合的发射功率的情况下，满足电磁能量吸收指标要求。
电磁能量吸收指标要求(或SAR法规)规定的测试方法是基于一段时间上的平均功率测试。3GPP标准普遍认为终端在23dBm的发射功率下可以实现满时隙发送，即FDD模式，这时满足SAR要求，并且系统设计没有余量。当终端工作在NR(新空口)SA(独立组网)最高功率模式(+26dBm)时，标准给出了默认50％(实际应用时可能改变)的上行时间占比限制。这样平均功率与23dBm的FDD模式等效。基于上述思想，在高功率载波聚合方案中，通过调整上行时间占比即上行时隙所占的比例，可以使终端的一段时间的平均发射功率满足电磁能量吸收指标要求(或SAR法规)。
此外，基站要调整终端的上行时间占比，调度上行资源需要获知终端的情况，但是，目前标准中没有关于高功率载波聚合场景下终端和基站的交互的相关设计。因此，后续方案中也将会重点针对信息的格式的设计提供解决方案。
图1为本公开终端能力指示方法一些实施例的流程图。如图1所示，该实施例的方法包括：步骤S102～S104。
在步骤S102中，终端确定在载波聚合的发射功率不超过最高功率等级的情况下， 支持的最大上行时间占比。
目前3GPP标准中最高功率等级对应的功率值为26dBm。载波聚合的发射功率不超过最高功率等级的情况对应于标准中Power Class 2的载波聚合场景。上行时间占比为在预设评估时间内上行传输调度的符号时间所占的比例，终端支持的最大上行时间占比可以预先配置。该最大上行时间占比使得终端在载波聚合的发射功率不超过最高功率等级的情况下，预设时间内终端的平均发射功率满足电磁能量吸收指标要求或SAR规定。
在步骤S104中，终端向基站发送能力指示信息，以便基站根据能力指示信息调度载波聚合中各个频段的载波的上行时隙资源。
能力指示信息包括最大上行时间占比。可以通过UE capability information elements(UE能力信息单元)中的BandCombinationList information element(载波聚合列表信息单元)将能力指示信息发送至基站。
首先针对能力指示信息的名称进行设计。在一些实施例中，能力指示信息的名称包括：表示最大上行时间占比的字段，表示载波聚合场景的字段以及表示最高功率等级的字段。通过该能力指示信息的名称的设计，可以通过名称直接获知该能力指示信息具体指示哪种能力。
在一些实施例中，能力指示信息的名称表示为：
maxUplinkDutyCycle-interBandCA-PC2，
maxUplinkDutyCycle-interBandCA-PC2-r17，
maxUplinkDutyCycle-CA-PC2，或者，
maxUplinkDutyCycle-CA-FDD-TDD-PC2。
maxUplinkDutyCycle为表示最大上行时间占比的字段，interBandCA表示带间载波聚合场景，CA表示载波聚合场景，PC2表示作为最高功率等级的功率等级2(Power Class 2)，r17表示3GPP版本17(Release 17)。
Power Class 2的载波聚合场景中聚合的每个频段的载波的功率等级可以是23dBm或者26dBm。可以包含以下表1中所示的4种场景。
Figure PCTCN2021132060-appb-000001
Figure PCTCN2021132060-appb-000002
针对上述4种场景，终端的能力指示信息的内容可以不同。在一些实施例中，能力指示信息的内容包括：表示载波聚合中每个频段的载波的最大发射功率所对应的功率等级的第一字段，以及该第一字段对应的表示最大上行时间占比的第二字段。
在一些实施例中，能力指示信息的内容包括以下一项或多项：
interBandCA-PC3-PC3-r17{x1}，
interBandCA-PC3-PC2-r17{x2}，
interBandCA-PC2-PC3-r17{x3}，以及
interBandCA-PC2-PC2-r17{x4}；
interBandCA-PC3-PC3-r17表示带间载波聚合中每个频段的载波的最大发射功率所对应的功率等级均为功率等级3(Power Class3，即每个频段的载波的最大发射功率为23dBm)，interBandCA-PC3-PC2-r17表示带间载波聚合中每个频段的载波的最大发射功率所对应的功率等级分别为功率等级3和功率等级2，即第一频段的载波的最大发射功率所对应的功率等级为功率等级3，第二频段的载波的最大发射功率所对应的功率等级为功率等级2，interBandCA-PC2-PC3-r17表示带间载波聚合中每个频段的载波的最大发射功率所对应的功率等级分别为功率等级2和功率等级3，即第一频段的载波的最大发射功率所对应的功率等级为功率等级2，第二频段的载波的最大发射功率所对应的功率等级为功率等级3，interBandCA-PC2-PC2-r17表示带间载波聚合中每个频段的载波的最大发射功率所对应的功率等级均为功率等级2，x1，x2，x3，x4分别表示不同第一字段对应的最大上行时间占比，即第二字段。
在另一些实施例中，能力指示信息的内容包括以下一项或多项：
interBandCA-Config0-r17{x1}，
interBandCA-Config1-r17{x2}，
interBandCA-Config2-r17{x3}，以及
interBandCA-Config3-r17{x4}；
interBandCA-Config0-r17，interBandCA-Config1-r17，interBandCA-Config2-r17，interBandCA-Config3-r17，分别表示带间载波聚合中每个频段的载波的最大发射功率所对应的功率等级的不同组合，不同组合包括：每个频段的载波的最大发射功率所对应的功率等级均为功率等级3，每个频段的载波的最大发射功率所对应的功率等级分 别为功率等级3和功率等级2(即第一频段的载波的最大发射功率所对应的功率等级为功率等级3，第二频段的载波的最大发射功率所对应的功率等级为功率等级2)，每个频段的载波的最大发射功率所对应的功率等级分别为功率等级2和功率等级3(即第一频段的载波的最大发射功率所对应的功率等级为功率等级2，第二频段的载波的最大发射功率所对应的功率等级为功率等级3)，每个频段的载波的最大发射功率所对应的功率等级均为功率等级2，x1，x2，x3，x4分别表示不同第一字段对应的最大上行时间占比，即第二字段。
终端在发送能力指示信息时可以根据实际配置情况从4种场景中选择性的上报一种或多种场景下，所支持的最大上行时间占比。上述能力指示信息的名称和内容的设计方式主要考虑标准中可能定义的体现形式。底层实际传输时，可能会采取编码的形式表示上述内容，例如，x1，x2，x3，x4分别为具体数值或表示具体数值的编码。
进一步，x1，x2，x3，x4的取值范围可以包括n50,n60,n70,n80,n90,n100，分别表示最大上行时间占比为50％，60％，70％，80％，90％，100％。因此，可以定义能力指示信息包括4个序列，分别为：
interBandCA-PC3-PC3-r17{n50,n60,n70,n80,n90,n100}
interBandCA-PC3-PC2-r17{n50,n60,n70,n80,n90,n100}
interBandCA-PC2-PC3-r17{n50,n60,n70,n80,n90,n100}
interBandCA-PC2-PC2-r17{n50,n60,n70,n80,n90,n100}
或者表示为：
interBandCA-Config0-r17{n50,n60,n70,n80,n90,n100}
interBandCA-Config1-r17{n50,n60,n70,n80,n90,n100}

interBandCA-Config3-r17{n50,n60,n70,n80,n90,n100}
上述定义的4个序列列出了终端上报的能力指示信息的内容的可能形式，实际上报时如前述实施例可以选择4种场景中一种或多种场景，每种场景下支持的最大上行时间占比进行上报，并且上报的最大上行时间占比使得终端在载波聚合的发射功率不超过最高功率等级的情况下，预设时间内终端的平均发射功率满足电磁能量吸收指标要求或SAR规定。
例如，终端上报的具体的能力指示信息可以定义为以下形式：
Figure PCTCN2021132060-appb-000003
Figure PCTCN2021132060-appb-000004
基站接收到终端的能力指示信息后，可以调度载波聚合中各个频段的载波的上行时隙资源以满足最大上行时间占比。在一些实施例中，基站确定载波聚合中各个频段的载波的上行时间占比，以使载波聚合后的上行时间占比不超过能力指示信息中的最大上行时间占比。
在一些实施例中，采用以下公式确定载波聚合中各个频段的载波的上行时间占比：
Figure PCTCN2021132060-appb-000005
其中，P NR,x表示新空口NR x频段的载波的最大线性发射功率，P NR,y表示新空口NR y频段的载波的最大线性发射功率，P CA分别x和y频段载波聚合的最大线性发射功率，Duty NR,x表示x频段的载波的上行时间占比，Duty NR,y表示y频段的载波的上行时间占比。
基站可以根据上述公式计算得到每个频段的载波的上行时间占比，进而可以调度每个频段的载波的资源以分别满足每个频段的载波的上行时间占比。
上述实施例的方法中终端确定载波聚合的发射功率不超过最高功率等级的情况下，支持的最大上行时间占比，该最大上行时间占比使得终端在载波聚合的发射功率不超过最高功率等级的情况下，预设时间内终端的平均发射功率满足电磁能量吸收指标要求或SAR规定。进而终端将包含最大上行时间占比的能力指示信息发送至基站，以使基站获知终端的能力，根据能力指示信息调度载波聚合中各个频段的载波的上行时隙资源，从而使终端在载波聚合的发射功率不超过最高功率等级的情况下，满足电磁能量吸收指标要求或SAR规定。
上述实施例中终端将支持的最大上行时间占比发送至基站，该最大上行时间占比是聚合载波的整体最大上行时间占比。在另一些实施例中，终端可以将载波聚合中各 个频段的载波的最大上行时间占比发送至基站，下面结合图2进行描述。
图2为本公开终端能力指示方法另一些实施例的流程图。如图2所示，该实施例的方法包括：步骤S202～S204。
在步骤S202中，终端确定在载波聚合的发射功率不超过最高功率等级的情况下，载波聚合中各个频段的载波的最大上行时间占比。
各个频段的载波的最大上行时间占比使得终端在载波聚合的发射功率不超过最高功率等级的情况下，预设时间内终端的平均发射功率满足电磁能量吸收指标要求(或SAR规定)。
在步骤S204中，终端向基站发送能力指示信息，以便基站根据能力指示信息调度载波聚合中各个频段的载波的上行时隙资源。
能力指示信息包括载波聚合中各个频段的载波的最大上行时间占比。可以通过UE capability information elements(UE能力信息单元)中的BandCombinationList information element(载波聚合列表信息单元)将能力指示信息发送至基站。
首先针对能力指示信息的名称进行设计。在一些实施例中，能力指示信息的名称包括：表示最大上行时间占比的字段，表示载波聚合场景的字段以及表示最高功率等级的字段。通过该能力指示信息的名称的设计，可以通过名称直接获知该能力指示信息具体指示哪种能力。
