在一些实施例中，终端设备的发射功率是由网络设备控制的。在一些实施例中，对于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、探测参考信号(Sounding Reference Signal，SRS)、解调参考信号(DeModulation Reference Signal，DMRS)、相位跟踪参考信号(Phase Tracking Reference Signal，PTRS)等都有单独的发射功率控制方法。
以下以PUSCH为例，对终端设备的发射功率控制进行说明，但是本申请不限于此，上述列举的其它信号(例如PUCCH、SRS、DMRS或PTRS等)的发射功率控制可以参见相关协议，本申请实施例对此不一一列举。
PUSCH的发射功率控制通过如下的公式(1)得到：
其中，b表示激活的上行带宽部分(Band Width Part，BWP)(active UL BWP)；f表示载波(carrier)；c表示服务小区；i表示PUSCH传输机会(PUSCH transmission occasion)；j表示参数集配置(parameter set configuration)索引；qd表示参考信号(Reference Signal，RS)资源索引(RS resource index)；μ对应于子载波间隔。
PCMAX,f,c(i)是终端设备的可配置的最大发射功率；PO_PUSCH,b,f,c(j)是网络设备配置的一个参考目标功率值，该值是PO_NOMINAL_PUSCH,f,c(j)(适用于小区内所有UE的目标功率值)与PO_UE_PUSCH,b,f,c(j)(针对特定UE的目标功率值)的和；是终端设备上行发射使用的RB资源数量；αb,f,c(j)是对路径损耗(Path Loss，PL)的加权值，也是网络配置的参数；PLb,f,c(qd)是终端设备与网络设备间的下行路径损耗值；ΔTF,b,f,c(i)是根据终端设备当前使用的调制编码方式做功率调整用的参数；fb,f,c(i,l)是网络设备可以通过闭环功控参数实时控制终端设备增加发射功率和降低发射功率的参数。
通过上述公式，可以看出发射功率的取值会受到PLb,f,c(qd)的影响。
功率余量(PH)为终端设备可配置的最大发射功率(即上述的PCMAX,f,c(i))跟终端设备的目标发射功率(即上述的PPUSCH,b,f,c(i,j,qd,l)这里简写为Ptarget)之差。在实施过程中，PCMAX,f,c(i)可以用Pcmax代替，或者也可以用其它字母代替。在实施过程中，PPUSCH,b,f,c(i,j,qd,l)可以用Ptarget代替，或者也可以用其它字母代替。例如，PH＝Pcmax-Ptarget。
在一些实施例中，PH通过MAC层信令进行上报。例如，终端设备可以上报第一信息，第一信息可以包括媒体接入控制控制单元(Medium Access Control Control Element，MAC CE)。可选地，该MAC CE可以为PHR MAC CE。可选地，该PHR MAC CE可以为单条目PHR MAC CE(也可以称固定大小MAC CE)或多条目PHR MAC CE(也可以称可变大小MAC CE)。
图2为本申请实施例提供的一种MAC CE的格式示意图，图3为本申请实施例提供的另一种MAC CE的格式示意图。图2中的MAC CE的格式为固定大小MAC CE的格式，图3中的MAC CE的格式为可变大小MAC CE的格式。图2和图3中的MAC CE的格式中，一行对应一个字节。
Cx域可以用于表示索引号为x的辅小区(Secondary Cell，SCell)是否上报功率余量(PH)；R域为保留位；P域用于表示是否应用功率回退；V域的取值可以为0或1；当V为1时，用于表示对应PH为基于参考格式计算得到的PH，当V为0时，用于表示对应PH为基于实际传输计算得到的PH；最大允许辐射量(Maximum Permissible Exposure，MPE)用于确定终端设备辐射对人体的影响是否符合标准。PCMAX,f,c、PCMAX,f,c1、PCMAX,f,c2、PCMAX,f,c3、PCMAX,f,cm域用于表示对应小区的最大发射功率。
PH(类型(Type)1，主小区(Primary Cell，PCell))域，用于表示PCell在Type 1下的PH。
PH(类型2，其它MAC实体的SpCell)域，用于表示其它MAC实体的SpCell在Type 2下的PH。其中，SpCell为PCell+主辅小区(Primary Secondary Cell，PSCell)。
PH(类型X，服务Cell(Serving Cell)1)域，用于表示服务Cell 1在Type X下的PH，X的取值可以是1或3。
PH(类型X，服务Cell n)域，用于表示服务Cell n在Type X下的PH，X的取值可以是1或3，n为大于1的整数，是服务Cell的索引号。
可选地，固定大小MAC CE或可变大小MAC CE中，还可以有其它PH域，例如，其它PH域可以包括以下至少之一：PH(类型2，PCell)域，用于表示PCell在类型(Type)2下的PH；PH(类型2，PUCCH SCell)域，用于表示被配置了PUCCH的SCell在Type 2下的PH；PH(类型2，PSCell)域，用于表示PSCell在Type 2下的PH等等，本申请实施例对此不作限制。
在一些实施例中，类型(Type)1可以指的是当前在小区中仅传输PUSCH时的PH。类型(Type)2可以指的是当前在小区中同时传输PUCCH和PUSCH时的PH。类型(Type)3可以指的是当前在小区中传输SRS时的PH。
需要说明的是，虽然图2和图3示出了两种MAC CE的格式示意图，但是本申请实施例不限于此，任何MAC CE的格式都应该在本申请的保护范围之内，例如，在另一些实施例中，MAC CE还可以有其它格式，例如，MAC CE可以包括一个字节，或者，MAC CE可以包括多个字节并且Cx中x的取值范围为1至31。
在公式(1)中，上行发射功率控制中的PLb,f,c(qd)为下行路径损耗值，即从网络设备到终端设备的路径损耗，该路径损耗包括以下至少之一：空间传播损耗、网络设备发射天线增益、终端设备接收天线损耗等，并将该路径损耗应用于终端设备的上行发射功率Ptarget的计算。可选地，在本申请任一实施例中，网络设备发射天线增益可以理解为或者可以称为或者可以为网络设备发射天线损耗。例如，网络设备发射天线增益为-A dB，则表示网络设备发射天线损耗为A dB.
图4为本申请实施例提供的一种下行路径损耗的示意图，如图4所示，下行路径损耗包括基站天线(即基站发射天线)增益、空间传播损耗以及终端设备天线(即终端设备接收天线)损耗。
然而，终端设备的下行路径损耗可能并不等于终端设备的上行路径损耗，比如对于频分双工(Frequency Division Duplex，FDD)频段来说上行与下行处于不同的工作频率，那么其传播损耗是不同的。另外，终端设备的发射天线与接收天线也存在差异，例如，终端设备的接收天线数量要多于发射天线数量。
图5为本申请实施例提供的一种终端设备收发天线差异的示意图，如图5所示，终端设备的接收天线数量可以为8个，而发射天线的数量为2个，即该终端设备可以为2T8R终端设备。在这种情况下，终端设备的下行天线接收性能要好于上行发射天线性能，且这种差异会随着接收天线数量的增多而变大。
需要说明的是，图5只是列举了一种终端设备的接收天线和发射天线的数量的示意，本申请实施例对终端设备的接收天线和发射天线的数量并不限定。例如，终端设备的接收天线的数量可以为其它，示例性地，终端设备的接收天线的数量可以为2、4或16等等。例如，终端设备的发射天线的数量可以为其它，示例性地，终端设备的发射天线的数量可以为1、4或8等等。
在公式(1)中，由于通过下行路径损耗来确定终端设备的发射功率，而终端设备的下行路径损耗可能并不等于终端设备的上行路径损耗，从而当前的终端设备的发射功率控制存在一定偏差，使得上报的PH在一定程度上偏离了终端设备的真实PH，导致网络设备对终端设备发射功率的调度过大或过小，进而影响终端设备的上行性能，例如降低了上行传输的可靠性。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上任一个或多个实施例中的方案作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。

以下对本申请实施例的通信方法进一步说明：
在相关技术中，终端设备发射目标功率(即上述的终端设备的发射功率)的计算中采用了以下行路径损耗为依据，然而由于上下行传播损耗的差异，和/或，终端设备发射天线与接收天线损耗的差异等，将导致计算出来的终端设备目标发射功率跟实际发射功率存在差异，进而导致PHR的上报偏离了终端设备的真实发射功率余量。为了解决该问题，本申请实施例提出引入一个第一调整值Pdelta，用于对上行发射功率进行调整。
以下说明Pdelta：
Pdelta用于描述终端设备对当前计算出来的目标发射功率进行修正的值。该值受空间传播损耗差值，和/或，终端设备收发天线增益差值等的影响，终端设备在修正其发射功率时可以考虑这些所有影响因素，也可以只考虑其中的部分影响因素。
在一些实施例中，Pdelta＝PTxLoss-PRxLoss。在另一些实施例中，为Pdelta＝PRxLoss-PTxLoss。以下以Pdelta＝PTxLoss-PRxLoss为例，对本申请的通信方法进行说明，需要说明的是，在Pdelta＝PRxLoss-PTxLoss的情况下，PH的确定与Pdelta＝PTxLoss-PRxLoss的确定方式对应，本申请实施例对此不作赘述。
PTxLoss和PRxLoss考虑了空间传播损耗和/或终端设备的收发天线损耗。
可选地，当同时考虑空间传播损耗和终端设备天线损耗时，PTxLoss＝发射空间传播损耗+发射天线损耗；PRxLoss＝接收空间传播损耗+接收天线损耗。
可选地，当仅考虑空间传播损耗时，PTxLoss＝发射空间传播损耗；PRxLoss＝接收空间传播损耗。
可选地，当仅考虑终端设备天线损耗时，PTxLoss＝发射天线损耗；PRxLoss＝接收天线损耗。
例如，当仅考虑空间传播损耗时，如果FDD频段的发射空间传播损耗比接收空间传播损耗小XdB，则Pdelta等于–XdB。又例如，当仅考虑终端设备天线损耗时，如果终端设备的发射天线损耗比接收天线损耗小XdB，则Pdelta等于–XdB。又例如，当同时考虑空间传播损耗和终端设备天线损耗时，如果FDD频段的发射空间传播损耗比接收空间传播损耗小XdB，且终端设备的发射天线损耗比接收天线损耗小XdB，则Pdelta等于–2XdB。
以下说明Pdelta对终端设备的发射功率的调整：
在按照相关技术中确定终端设备的发射功率为Ptarget的情况下，修正后的发射功率或者调整后的发射功率可以为Ptarget+Pdelta。
Pdelta包括了上下行空间传播损耗差异，和/或，发射与接收天线损耗差异。可选地，在本申请任一实施例中，发射与接收天线损耗可以理解为或者可以称为或者可以为发射与接收天线增益。例如，发射天线增益为-A dB，则表示发射天线损耗为A dB。又例如，接收天线增益为-B dB，则表示接收天线损耗为B dB。
可选地，终端设备可以通过测量下行参考信号(如SSB)的接收信号强度RSRP，以及该参考信号在基站侧的发送信号强度P0，得到空间传播损耗为P0-RSRP(即下行空间传播损耗)。可选地，在本申请任一实施例中，接收信号强度可以称为接收功率强度，发送信号强度可以称为发送功率强度。
可选地，终端设备根据上行与下行的频率差异可以计算得到空间传播损耗的差异值。示例性，终端设备可以按照空间传播损耗公式R＝32.4+20*log10D+20*log10M，计算得到某个工作频率的空间传播损耗，从而根据该公式和上下行工作频率，确定上下行空间传播损耗差异。需要说明的是，本申请实施例并不限定计算空间路径损耗的方式，或者说还可以按照其它方式计算空间传播损耗，此处不再赘述。其中，公式R＝32.4+20*log10D+20*log10M中，D为无线信号的自由空间传播距离，单位为千米；M为工作频率，单位为MHz(兆赫兹)。R为损耗值，单位为dB。
可选地，网络设备可以测量得到上行空间传播损耗，例如网络设备可以根据终端设备发送的SRS确定。然而相关技术中网络设备无法确定终端设备发送SRS的信号强度，因此网络设备无法测量得到上行空间传播损耗。
在本申请实施例中，引入终端设备上报终端设备发送SRS的发送信号强度，即终端设备在发送SRS时，将发射SRS的发送信号强度(SRStx)上报给网络设备，网络设备接收并测量该SRS的信 号强度，得到接收信号强度(SRSrx)，网络设备可以得到上行传播损耗值为SRStx-SRSrx。网络设备可以将上行传播损耗值发送给终端设备，从而终端设备可以得到该上行传播损耗值，并将该上行传播损耗值应用于终端设备的发射功率的调整。
在一些实施例中，终端设备的发射天线数量通常都会比接收天线数量少，这导致发射天线的损耗(或者说增益)会不同于接收天线。比如终端设备的发射天线损耗比接收天线损耗小XdB，那么Pdelta等于-XdB等。对于终端设备来说，其发射和接收天线损耗(或者说增益)等是已知的，该值可以存储于终端设备内部，并应用于Pdelta的计算。
以下说明Pdelta的上报：
由于终端设备的发射功率相比相关技术得到的目标发射功率进行了调整，那么也需要考虑如何将该调整值告知基站。
在一些实施例中，终端设备可以通过PHR上报。示例性地，终端设备可以将Pdelta或者将使用Pdelta的指示信息，反映到PHR上报中，以使得PHR能够反映真实的终端设备发射功率及余量。
相关技术中，终端设备的PH是Pcmax与Ptarget的差值，即PH＝Pcmax-Ptarget。在本申请实施例中，由于通过Pdelta对终端设备的发射功率进行了调整，从而本申请实施例中的PH＝Pcmax-(Ptarget+Pdelta)。
在PHR上报中，进一步的可以将Pdelta也上报给基站，以供基站参考上下行的实际损耗差异。
可选地，如图2和图3所述，终端设备可以通过MAC CE中的保留比特(R比特)，来指示在上报的PHR中是否采用了Pdelta调整值。不过这种方式只能告知基站当前终端设备的发射功率是否采用了Pdelta调整，但具体调整值是多少并不告诉基站。
可选地，终端设备可以引入新的比特将Pdelta调整值一并上报上去。
图8为本申请实施例提供的又一种MAC CE的格式示意图，如图8所示，图8中的MAC CE为固定大小MAC CE的格式，图8中的MAC CE的格式中，一行对应一个字节。
R域为保留位；P域用于表示是否应用功率回退；最大允许辐射量(Maximum Permissible Exposure，MPE)用于确定终端设备辐射对人体的影响是否符合标准。
图8中的第一行的从左到右的第3至8个比特用于承载PH值，第二行的从左到右的第3至8个比特用于承载Pcmax，第三行的8个比特用于承载Pdelta。
需要说明的是，承载Pdelta的比特为第三行的所有比特。在其它实施例中，承载Pdelta的比特可以为第三行中的部分比特，或者承载Pdelta的比特可以为MAC CE中的第二行，而MAC CE中的第三行承载Pcmax。本申请实施例并不限定用于承载Pdelta的比特的位置。
在一些实施例中，上下行空间传播损耗差异以及终端设备的收发天线损耗差异通常是相对不变的，这两个差异与工作频段相关。因此可以通过终端设备能力信息这种相对静态的能力将各频段的Pdelta调整值进行上报。
在一些实施例中，可以在实际传输中结合上述PHR上报方式，来进行指示是否在当前发射功率中采用了这个Pdelta调整值。当然，也可以采用默认的方式，比如默认只要终端设备上报了这个各频段的Pdelta调整值能力信息，就默认终端设备是会在发射功率时采用这个Pdelta调整值。
以下说明Pdelta调整的能力及基站控制：
可选地，终端设备调整其发射功率的方法(通过Pdelta调整发射功率)可以认为是个特性，终端设备需要告诉基站其是否支持该特性，也即相应的终端设备能力。这个能力的上报可以有两种方式：
方式1：通过如前面所述的上报Pdelta调整值来隐含告诉基站其支持这个特性，这时候只需要上报：终端设备在各个频段的Pdelta值。
方式2：定义个单独的能力信息，这时候终端设备的能力信息会包括以下内容：终端设备是否支持通过Pdelta调整发射功率；终端设备在各个频段的Pdelta值。
可选地，除了上述终端设备能力的上报之外，还可以进一步引入基站的控制，也即由基站决定终端设备是否对其发射功率进行Pdelta调整。当基站允许终端设备进行发射功率调整时，该特性才在终端设备侧被激活，否则不激活。具体的基站控制方式可以为定义控制信令(RRC或MAC或DCI等信令方式)，比如：激活Pdelta调整指令(EnablePdelta)或不激活Pdelta调整指令(DisablePdelta)。
本申请实施例给出了一种发射功率调整的方法。在该方法中，入Pdelta用于对当前计算出来的目标发射功率进行修正，克服由于上下行传播损耗的差异、终端设备发射与接收天线的差异等带来的终端设备目标发射功率跟实际发射功率的差异，以及由此带来的PHR上报值偏离终端设备真实发射功率余量的问题。另外，本申请实施例提出了Pdelta的定义、对发射功率的调整以及相关信令的上报等内容。
在本申请实施例中，通过引入Pdelta调整功率可以使得终端设备的发射功率更加贴近实际终端设备需要发射的功率，克服由于上下行频率差异带来的空间传播损耗差异以及由于终端设备的收发天线差异带来的损耗差异等。
本申请实施例的通信方法，可以解决终端设备实际需要的发射功率与当前计算的发射功率不一致的问题，以及PHR上报值与实际情况不符的问题。
