下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的功率余量上报和接收方法进行详细地说明。
如图2a所示，本申请实施例提供一种功率余量上报方法200，该方法可以由终端执行，换言之，该方法可以由安装在终端的软件或硬件来执行，该方法包括如下步骤。
S202：终端发送目标PHR消息，所述目标PHR消息包括如下至少之一：第一指示；目标功率回退；目标功率余量；MUSIM终端最大发射功率；PHR类型为MUSIM类型的功率余量；PHR类型为MUSIM类型的MPE或P-MPR。
本申请各个实施例中提到的终端可以为多用户识别卡(Multi-Universal Subscriber Identity Module，MUSIM)终端(MUSIM UE)或所述终端支持双接收和/或双发送(Dual-Rx/Dual-Tx)。终端中可以包含多个UE，这多个UE中的一个UE或多个UE均可以发送目标PHR消息。需要说明的是，UE可以认为是签约主体。一个实体终端上可以配置有多个签约主体。签约主体可以通过用户识别卡(Subscriber Identity Module，SIM)体现。一个SIM卡对应一个网络的签约主体。SIM卡中保存着签约主体的标识，即UE的标识，比如用户身份标识(Subscription Permanent Identifier，SUPI)，或国际移动订阅标识(International Mobile Subscription Identity，IMSI)等。所以一个终端上插入多个SIM 卡或配置多个电子SIM卡信息时，终端与不同的签约主体可以构成不同的UE。
所述第一指示用于指示所述目标PHR消息由MUSIM操作触发或指示所述目标PHR消息所上报的参数与MUSIM相关，该参数例如包括如下列出的目标功率回退，目标功率余量，MUSIM终端最大发射功率等。可选地，所述第一指示可以为MUSIM指示或双发送和/或双接收指示。
本申请各个例子中提到的MUSIM操作可以包括MUSIM双发送和/或双接收操作。
所述目标功率回退包括为了执行MUSIM操作而应用的功率回退值，该目标功率回退值可以包括功率管理-最大功率降低(Power Management-Maximum Power Reduction，P-MPR)或最大容许辐照量(Maximum Permissible Exposure，MPE)。所述目标功率回退用于指示为了执行MUSIM操作而应用的功率回退，如MUSIM P-MPR或MSUIM MPE，或用于指示受MUSIM影响的P-MPR或MPE。
所述目标功率余量包含MUSIM影响的功率余量值。
MUSIM终端包括多个UE，MUSIM终端最大发射功率可以是MUSIM终端中的一个UE的最大发射功率。MUSIM终端最大发射功率可以是用于计算功率余量的服务小区最大发射功率。
所述PHR类型为MUSIM类型的MPE或P-MPR用于指示MUSIM终端为满足MPE需求时的功率回退，该MUSIM终端可以是MUSIM UE中的任意一个UE。
本申请实施例提供的功率余量上报方法，终端发送目标PHR消息，所述目标PHR消息包括如下至少之一：第一指示；目标功率回退；目标功率余量；MUSIM终端最大发射功率；PHR类型为MUSIM类型的功率余量；PHR类型为MUSIM类型的MPE或P-MPR，解决了终端无法上报因MUSIM导致的功率余量的问题，使网络侧设备和终端对功率余量状态有一致的理解，有利于终端的功率控制。
本申请实施例可以解决MUSIM UE的功率余量上报问题，包括因为MUSIM双接收和/或双发送引起的功率回退(power backoff)，MUSIM影响的功率余量值，或变更的终端最大发射功率等，使网络侧设备和终端对功率余量状态有一致的理解，有利于终端的功率控制。
可选地，本申请各个实施例中的目标PHR消息用于以下至少之一的目的的PHR上报：
1)MUSIM。因为处于同一个设备的多个UE的总发射功率不能超过终端的最大发射功率，因此，MUSIM可能影响单个UE的功率余量。
2)双接收和/或双发送。因为处于同一个设备的多个UE的总功率不能超过终端的最大发射功率，双接收和/或双发送可能影响单个UE的功率余量。
3)MUSIM MPE限制或特定吸收率(Specific Absorption Rate，SAR)限制。MUSIM UE因为MPE或SAR的限制从而降低终端的最大发射功率，可能影响单个UE的功率余量。
4)过热(overheating)。终端因为器件过热会限制最大发射功率。
5)设备内总发射功率限制。即终端内有多个UE的发射实体，因为限制总发射功率而导致的功率余量变化。
可选地，所述目标PHR消息包括媒体接入控制控制单元(Media Access Control Control Element，MAC CE)，所述MAC CE包括单条目(entry)PHR MAC CE或多条目PHR MAC CE。
所述目标PHR消息包括：类型1PHR，类型2PHR，类型3PHR或MUSIM类型PHR。该实施例中，所述目标PHR消息适用于终端的单个MAC实体或全部MAC实体。应用于终端全部MAC实体的好处是：减少PHR消息的上报量；应用于单个MAC实体的好处是：便于终端来按不同的MAC实体来上报PHR消息，从而灵活调节不同MAC实体的功率分布。
可选地，所述目标PHR消息包括MAC CE，所述MAC CE的MAC子头包括逻辑信道标识(Logical Channel IDentifier，LCID)，所述LCID用于指示所述MAC CE的格式为MUSIM PHR MAC CE。
可选地，终端发送的目标PHR消息可以包括PHR类型为MUSIM类型的功率余量，所述MUSIM类型的功率余量可以用于指示为以下之一的发射而估计的发射功率与MUSIM终端最大发射功率之间的差值：
1)激活的服务小区上上行共享信道(UL-SCH)发射。
2)其他MAC实体的特殊小区(SpCell)上UL-SCH和物理上行控制信道(Physical Uplink Control Channel，PUCCH)发射。
3)激活的服务小区上探测参考信号(Sounding Reference Signal，SRS)发射。
该实施例中，MUSIM终端最大发射功率与普通终端最大发射功率不同。
该实施例中，所述MUSIM类型的功率余量用于主小区(PCell)，其他MAC实体的SpCell或激活的服务小区。
可选地，本申请各个实施例中，所述终端发送目标PHR消息之前，所述方法还包括：所述终端接收无线资源控制(Radio Resource Control，RRC)消息，所述RRC消息包括有用于控制所述目标PHR消息上报的参数。
所述RRC消息可以包括如下1)至15)至少之一：

2)是否允许上报MUSIM P-MPR的指示。即指示终端是否允许上报MUSIM P-MPR。
3)MUSIM功率余量上报周期定时器(MUSIM phr-PeriodicTimer)。用于MUSIM PHR的周期性上报，值可以为MUSIM PHR报告的子帧数。
4)MUSIM功率余量上报禁止定时器(MUSIM phr-ProhibitTimer)。用于MUSIM PHR的周期性禁止上报，值可以为MUSIM PHR报告的子帧数。
5)第一最大功率降低值，所述第一最大功率降低值是用于所述终端的最大功率降低值。
6)MUSIM功率余量上报发射功率变化因子(MUSIM phr-Tx-PowerFactorChange)。指示用于MUSIM终端PHR上报的功率余量变化量的门槛值，相同的值适用于每个服务小区。
7)其他小区的MUSIM类型2功率余量上报(MUSIM phr-Type2OtherCell)。该参数字段如果设置为真，MUSIM终端应报告其他MAC实体的SpCell的PHR类型2。如果终端未配置E-UTRA MAC实体，网络侧设备将此字段设置为假。
8)其他小区组的MUSIM功率余量上报模式(MUSIM phr-ModeOtherCG)。当为MUSIM终端配置双连接(Dual-Connectivity，DC)时，指示作为其他小区组(即MCG或SCG)一部分的激活小区的PHR所使用的模式(即真实或虚拟)。如果MUSIM终端仅配置了一个小区组(无DC)，则会忽略该字段。
9)MUSIM多功率余量上报(MUSIM multiplePHR)。指示是否应使用单条目PHR MAC CE或多条目PHR MAC CE报告功率余量。真表示使用多条目PHR MAC CE，假表示使用单条目PHR MAC CE。对于NR的多无线接入技术双连接(Multi Rat-Dual Connectivity，MR-DC)和上行(UL)载波聚合(Carrier Aggregation，CA)MUSIM终端，网络侧设备将该字段配置为真，在所有其他情况下配置为假。
10)MUSIM最大容许辐照量上报(MUSIM mpe-Reporting)。指示终端是否应在PHR MAC CE中报告MUSIM MPE P-MPR。
