本公开实施例涉及通信技术领域，尤其涉及一种功率控制方法及设备。
背景技术
在新空口(new radio，NR)系统中，旁链路(sidelink，SL)技术可以支持发送端设备通过开环功率控制(open loop power control，OLPC)的方式控制其发送功率。如此，可以使得接收端设备能够接收到发送端设备发送的信道、信号、信息等。
目前，以发送端设备为用户设备(user equipment，UE)为例，UE可以根据UE与基站之间的路径损耗(以下称为路径损耗1)进行开环功率控制，也可以根据UE与UE之间的路径损耗(以下称为路径损耗2)进行开环功率控制，还可以根据路径损耗1和路径损耗2进行开环功率控制。例如，在单播传输模式中，UE可以根据UE和UE之间的路径损耗，即上述路径损耗2进行开环功率控制。
然而，在SL技术中，对于不同信道、信号或信息，具体采用上述何种方式进行开环功率控制是一个亟待解决的问题。
发明内容
本公开实施例提供一种功率控制方法及设备，以解决对于不同信道、信号或信息，采用何种方式进行开环功率控制的问题。
为了解决上述技术问题，本公开是这样实现的：
第一方面，本公开实施例提供了一种功率控制方法，该方法可以应用于UE，该方法包括：采用目标发送功率，发送目标对象，目标对象为进行功率控制后的对象，目标发送功率根据第一功率和第二功率确定，第一功率为UE的最大发送功率，第二功率为与目标对象对应的功率；其中，第二功率包括以下至少一项：蜂窝链路传输功率、旁链路传输功率。
第二方面，本公开实施例提供了一种UE，该UE包括发送模块。发送模块，用于采用目标发送功率，发送目标对象，目标对象为进行功率控制后的对象，目标发送功率根据第一功率和第二功率确定，第一功率为UE的最大发送功率，第二功率为与目标对象对应的功率；其中，第二功率包括以下至少一项：蜂窝链路传输功率、旁链路传输功率。
第三方面，本公开实施例提供了一种UE，包括处理器、存储器及存储在该存储器上并可在该处理器上运行的计算机程序，该计算机程序被该处理器执行时实现上述第一方面提供的功率控制方法的步骤。
第四方面，本公开实施例提供了一种计算机可读存储介质，该计算机可读存储介质上 存储计算机程序，该计算机程序被处理器执行时实现上述第一方面提供的功率控制方法的步骤。
在本公开实施例中，UE可以采用目标发送功率，发送目标对象(进行功率控制后的对象)，其中，目标发送功率根据第一功率和第二功率确定，第一功率为UE的最大发送功率，第二功率为与目标对象对应的功率；第二功率包括以下至少一项：蜂窝链路传输功率、旁链路传输功率。通过该方案，由于UE要发送的目标对象均有与其对应的第二功率，例如目标对象对应的第二功率为蜂窝链路传输功率，或者目标对象对应的第二功率包括蜂窝链路传输功率和旁链路传输功率等，因此UE可以根据UE实际要发送的目标对象，采用与该目标对象对应的功率对其进行开环功率控制。如此，对于不同的对象(例如信道、信号，以及信息等)，UE可以采用与该对象对应的功率对其进行开环功率控制。

其中，上述第一对象可以为参考信号或旁链路反馈控制信息。
可选的，对于上述情况一，上述蜂窝链路传输功率和旁链路传输功率均可以为与旁链路共享信道对应的传输功率。其中，蜂窝链路传输功率可以为蜂窝链路(即UE与网络设备之间的链路)上旁链路共享信道对应的传输功率，旁链路传输功率可以为旁链路(即UE与其他UE之间的链路)上旁链路共享信道对应的传输功率。
具体的，上述蜂窝链路传输功率(记为P UU_PSSCH)可以为：
P UU_PSSCH＝P 0_DL_PSSCH+α DL_PSSCH*PL DL+10log10(M PSSCH)；
其中，P 0_DL_PSSCH为接收端设备(可以为网络设备)期望接收到的功率值，α DL_PSSCH为蜂窝链路对应的路径损耗补偿因子，PL DL为下行路径损耗(蜂窝链路路径损耗中的路径损耗)，M PSSCH为旁链路共享信道的带宽。P 0_DL_PSSCH和α DL_PSSCH均可以为配置给UE的固定值，且均与发送旁链路共享信道的资源(例如时域资源等)关联。
上述旁链路传输功率(记为P SL_PSSCH)可以为：
P SL_PSSCH＝P 0_SL_PSSCH+α SL_PSSCH*PL SL+10log10(M PSSCH)+Δ TF；

示例性的，当UE未处于网络设备覆盖范围内(即UE处于网络设备覆盖范围外)时，上述第一开关参数可以为无穷大(即a＝inf)，上述第二开关参数可以为1(即b＝1)。
又示例性的，上述目标对象的传输模式为组播模式时，上述第一开关参数可以为1(即a＝1)，上述第二开关参数可以为无穷大(即b＝inf)。
本公开实施例中，对于上述方式一，上述目标发送功率(记为P X)可以为UE的最大发送功率(记为P max)、蜂窝链路传输功率(即a×P UU_PSSCH)和旁链路传输功率(即b×P SL_PSSCH)中的最小值，即P X可以为：P X＝min{P max，a×P UU_PSSCH，b×P SL_PSSCH}。
示例性的，假设UE的最大发送功率为23分贝毫瓦(dBm)，P max＝23dBm；且UE位于网络设备覆盖范围内；以及UE接收到网络设备的配置信息为：仅基于旁链路路径损耗(PL SL)进行开环功率控制，且网络设备向UE配置P 0_SL_PSSCH的值和α SL_PSSCH的值。那么，UE可以根据网络设备的配置信息确定上述第一开关参数为：a＝inf，上述第二开关参数为：b＝1。如此，在UE根据旁链路路径损耗(PL SL)和旁链路共享信道的带宽(M PSSCH)计算得到旁链路传输功率(P SL_PSSCH)为：P SL_PSSCH＝20dBm的情况下，UE可以确定上述目标发送功率(P X)为：

方式二：蜂窝链路传输功率可以根据蜂窝链路路径损耗确定，旁链路传输功率可以根据旁链路路径损耗确定。
其中，蜂窝链路路径损耗可以根据网络设备的配置信息确定，或根据UE是否处于网络设备的覆盖范围内确定；旁链路路径损耗可以根据网络设备的配置信息确定，或根据上述目标对象的传输模式确定。
需要说明的是，本公开实施例中，上述蜂窝链路路径损耗和旁链路路径损耗还可以通过其它任意可能的方式确定，具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，对于上述方式二，当UE满足第一条件时，UE可以将蜂窝链路路径损耗(具体可以为下行路径损耗，即PL DL)设置为特殊值，或者，当UE满足第二条件时，UE可以将旁链路路径损耗(即PL SL)设置为特殊值。
可选的，本公开实施例中，上述第一条件可以为网络设备的配置信息指示UE仅使用旁链路路径损耗确定上述目标发送功率；或者，第一条件也可以为UE处于网络设备的覆盖范围外(即UE未处于网络设备覆盖范围内)。
可选的，本公开实施例中，上述第二条件可以为网络设备的配置信息指示UE仅使用蜂窝链路路径损耗确定上述目标发送功率；或者，第二条件也可以为上述目标对象的传输模式为组播模式。
当然，实际实现时，上述第一条件和第二条件还可以为其它任意可能的条件，具体可以根据实际使用需求确定，本公开实施例不作限定。

可选的，本公开实施例中，上述特殊值可以为无穷大等任意可能的数值。具体可以根据实际使用需求确定，本公开实施例不作限定。
需要说明的是，本公开实施例中，由于蜂窝链路传输功率(P UU_PSSCH)可以为：P UU_PSSCH＝P 0_DL_PSSCH+α DL_PSSCH*PL DL+10log10(M PSSCH)，因此，当UE将蜂窝链路路径损耗 (PL DL)设置为无穷大时，蜂窝链路传输功率也为无穷大，即P UU_PSSCH＝inf。由于旁链路传输功率(P SL_PSSCH)可以为：P SL_PSSCH＝P 0_SL_PSSCH+α SL_PSSCH*PL SL+10log10(M PSSCH)+Δ TF，因此，当UE将旁链路路径损耗(PL SL)设置为无穷大时，旁链路传输功率也为无穷大，即P SL_PSSCH＝inf。
本公开实施例中，对于上述方式二，上述目标发送功率(P X)可以为UE的最大发送功率(P max)、蜂窝链路传输功率(即P UU_PSSCH)和旁链路传输功率(即P SL_PSSCH)中的最小值，即P X可以为：P X＝min{P max，P UU_PSSCH，P SL_PSSCH}。
示例性的，本公开实施例中，当UE将蜂窝链路路径损耗(PL DL)设置为无穷大时，蜂窝链路传输功率可以为无穷大(P UU_PSSCH＝inf)，如此上述目标发送功率可以为P X＝min{P max，P SL_PSSCH}；当UE将旁链路路径损耗(PL SL)设置为无穷大时，旁链路传输功率可以为无穷大(P SL_PSSCH＝inf)，如此上述目标发送功率可以为P X＝min{P max，P UU_PSSCH}。
可选的，本公开实施例中，上述目标发送功率还可以为UE通过上述情况一的方式获取的功率进行功率提升(power boosting)后的功率。
需要说明的是，本公开实施例中，上述功率提升可以与传统技术中的功率提升相同或类似，具体可以根据实际使用需求确定，本公开实施例不作限定。

其中，上述第三时域资源可以为旁链路共享信道和旁链路控制信道复用的时域资源。
本公开实施例中，对于上述第二种实现方式，当旁链路共享信道和旁链路控制信道复用时域资源(即上述第三时域资源)时，UE可以在该第三时域资源中的每个时域单元上，采用上述第七功率发送旁链路共享信道，并采用第八功率发送旁链路控制信道，如此可以使得上第三时域资源中的每个时域单元对应的发送功率相同(即每个时域单元对应的发送功率为上述目标发送功率)。
第三种实现方式：目标发送功率为上述第九功率。
需要说明的是，本公开实施例中，对于上述第三种实现方式中涉及的第七功率和第八功率与上述第二种实现方式中的第七功率和第八功率为相同。
可选的，本公开实施例中，对于上述第三种实现方式，目标对象为：旁链路共享信道和旁链路控制信道，在上述第七功率和第八功率之和大于上述第一功率的情况下，上述目标发送功率可以为第九功率，上述S202具体可以通过下述的S202f实现。

方法1：在上述第七功率(记为P 3)和第八功率(记为P 4)之和大于上述第一功率(P max) 的情况下，UE可以对P 3和P 4进行等比例缩减，直至P 3和P 4之和小于或等于P max。缩减后的P 3即为上述第九功率，缩减后的P 4即为上述第十功率。
可以理解，对于上述方法1，上述第九功率可以为第七功率与比例系数的商，上述第十功率可以为第八功率与比例系数的商，该比例系数可以为第七功率和第八功率之和与上述第一功率的比值。
示例性的，如图4所示，假设旁链路共享信道和旁链路控制信道的复用资源为图4中的31指示的部分，其中，对于图4中的31指示的部分，旁链路共享信道的带宽为20RB，旁链路控制信道的带宽为30RB，且UE的最大发送功率为23dBm(即上述第一功率，P max＝23dBm＝0.2w)，且图4中的31指示的部分上的旁链路共享信道对应的功率(即上述第七功率)为20dBm(P 3＝20dBm＝0.1w)，旁链路控制信道对应的功率(即上述第八功率)为21dBm(P 4＝21dBm＝0.126w)，即第七功率和第八功率之和(P 3+P 4＝0.1+0.126＝0.226w)大于上述第一功率。那么，UE可以对第七功率和第八功率进行等比例缩减，具体可以为：
Figure PCTCN2020104928-appb-000019
且

如此，通过计算可以得到缩减后的第七功率(记为P 3')为P 3'＝0.0885w＝19.47dBm，即上述第九功率为19.47dBm，缩减后的第八功率(记为P 4')为P 4'＝0.1115w＝20.47dBm，即上述第十功率为20.47dBm。
方法2：在上述第七功率(记为P 3)和第八功率(记为P 4)之和大于上述第一功率(P max)的情况下，UE可以按照优先级从高到低的顺序，优先给优先级较高的信道分配发送功率，直至将P max分配完。
可以理解，对于上述方法2，上述第九功率为第七功率，上述第十功率为上述第一功率与第九功率的差值；还是上述第十功率为第八功率，上述第九功率为第一功率与第十功率的差值，具体可以根据旁链路共享信道的优先级和旁链路控制信道的优先级确定。
本公开实施例中，当旁链路共享信道的优先级高于旁链路控制信道的优先级时，上述第九功率可以为上述第七功率，上述第十功率可以为上述第一功率与第九功率的差值；当旁链路控制信道的优先级高于旁链路共享信道的优先级时，上述第十功率可以为上述第八功率，上述第九功率可以为上述第一功率与第八功率的差值。

当然，实际实现时，信道的优先级还可以包括其它任意可能的优先级，具体可以根据实际使用需求确定，本公开实施例不作限定。
示例性的，如图4所示，假设旁链路共享信道和旁链路控制信道的复用资源为图4中的31指示的部分，其中，对于图4中的31指示的部分，旁链路共享信道的带宽为20RB，旁链路控制信道的带宽为30RB，且链路控制信道的优先级高于旁链路共享信道的优先级，以及UE的最大发送功率为23dBm(即上述第一功率，P max＝23dBm＝0.2w)，且图4中的31指示的部分上的旁链路共享信道对应的功率(即上述第七功率)为20dBm(P 3＝20dBm＝0.1w)，旁链路控制信道对应的功率(即上述第八功率)为21dBm(P 4＝21dBm＝0.126w)，即第七功率和第八功率之和(P 3+P 4＝0.1+0.126＝0.226w)大于上述第一功率。那么，UE可以优先为旁链路控制信道分配功率，即上述第十功率可以为上述第八功率(P 4＝0.126w＝21dBm)，然后再为旁链路共享信道分配功率，即上述第九功率 可以为第一功率与第十功率的差(P max-P 4＝0.2-0.126＝0.074w＝18.7dBm)。
可选的，本公开实施例中，目标对象包括旁链路共享信道和旁链路控制信道，上述S202具体可以通过下述的S202g实现。

其中，上述第一旁链路共享信道为旁链路共享信道中与旁链路控制信道复用时域资源的信道，上述第二旁链路共享信道为旁链路共享信道中未与旁链路控制信道复用时域资源的信道。
上述第四目标功率(记为P PSSCH1)可以根据第一传输功率(记为P RB)、第一旁链路共享信道的带宽(记为M PSSCH1)和第一参数(记为Y)确定。具体的，第四目标功率(P PSSCH1)可以为：P PSSCH1＝P RB+10log10(M PSSCH1)+Y。
上述第五目标功率(记为P PSSCH2)可以根据第一传输功率(记为P RB)、第二旁链路共享信道的带宽(记为M PSSCH2)和第一参数(记为Y)确定。具体的，第五目标功率(P PSSCH2)可以为：P PSSCH2＝P RB+10log10(M PSSCH2)+Y。
上述第六目标功率(记为P PSCCH)可以根据第一传输功率(记为P RB)、旁链路控制信道的带宽(记为M PSCCH)和旁链路控制信道的功率提升量(X)确定。具体的，第六目标功率(P PSCCH)可以为：P PSCCH＝P RB+10log10(M PSCCH)+X。
可选的，本公开实施例中，上述第一传输功率(记为P RB)可以根据接收端设备期望接收到的功率值(P 0)、路径损耗补偿因子(α)和路径损耗(PL)确定。具体的，第一传输功率(P RB)可以为：P RB＝P 0+α*PL。
可选的，本公开实施例中，上述路径损耗可以为下行路径损耗，也可以为旁链路路径损耗，还可以为下行路径损耗和旁链路路径损耗中的最大值或最小值。具体可以根据实际使用需求确定，本公开实施例不作限定。
可选的，本公开实施例中，上述第一参数可以根据第二参数(记为m)、旁链路控制信道的功率提升量、旁链路共享信道的带宽(第一旁链路共享信道的带宽或第一旁链路共享信道的带宽)和旁链路控制信道的带宽确定。具体的，第一参数(Y)可以为：

需要说明的是，对于上述第四目标功率，上述第二参数可以为0，即m＝0，旁链路共享信道的带宽可以为第一旁链路共享信道的带宽(即M PSSCH＝M PSSCH1)；对于上述第五目标功率，上述第二参数可以为1，即m＝1，旁链路共享信道的带宽可以为第二旁链路共享信道的带宽(即M PSSCH＝M PSSCH2)。
当然，实际实现时，UE还可以按照其它任意可能的方式控制上述目标对象中的各个对象的发送功率，具体可以根据实际使用需求确定，本公开实施例不作限定。
本公开实施例提供一种功率控制方法，由于UE要发送的目标对象均有与其对应的第二功率，例如目标对象对应的第二功率为蜂窝链路传输功率，或者目标对象对应的第二功率包括蜂窝链路传输功率和旁链路传输功率等，因此UE可以根据UE实际要发送的目标对象，采用与该目标对象对应的功率对其进行开环功率控制。如此，对于不同的对象(例如信道、信号，以及信息等)，UE可以采用与该对象对应的功率对其进行开环功率控制。
需要说明的是，本公开实施例中，上述各个附图所示的功率控制方法均是以结合本公 开实施例中的一个附图为例示例性的说明的。具体实现时，上述各个附图所示功率控制方法还可以结合上述实施例中示意的其它可以结合的任意附图实现，此处不再赘述。
