Description

一种功率控制方法、相关装置及产品
本申请要求于2018年02月01日提交中国专利局、申请号为201810103897.9、发明名称为“一种功率控制方法、相关装置及产品”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种功率控制方法、相关装置及产品。
背景技术
未来5G无线通信主要包括3大应用场景，增强型移动宽带(enhanced mobile broadband，eMBB)、高可靠低时延(ultra-reliable and low latency communications，URLLC)和大规模机器通信(massive machine type communications，mMTC)，5G无线通信系统中的非正交多址接入(non-orthogonal multiple access，NOMA)技术允许在同一时频资源上传输多个用户数据。
对于同一个用户设备(user equipment，UE)而言，UE在传输物理上行共享信道(physical uplink shared channel，PUSCH)时，可能在同一时频资源上既存在第一类型的PUSCH也存在第一类型的PUSCH，两种类型的PUSCH会根据标准中的功率控制公式以及自己的功率控制参数，独立计算各自的传输功率，两种类型的PUSCH各自的传输功率都不会超过UE用于传输PUSCH的最大传输功率。
而当UE需要同时传输这两种类型的PUSCH时，则可能出现UE当前的发送总功率超过了UE用于传输PUSCH的最大传输功率，影响了接收端对信号的正常接收。
发明内容
本申请实施例提供了一种功率控制方法、相关装置及产品，用于使接收端可以正常接收信号。
有鉴于此，本申请实施例第一方面提供了一种功率控制方法，包括：
UE确定第一类型的PUSCH的初始发送功率，其中，第一类型的PUSCH可以是用于传输低优先级的时延要求较低的业务，例如eMBB业务，根据3GPP TS 38.213标准中规定的公式可以计算出该第一类型的PUSCH的初始发送功率；
当有第二类型的PUSCH需要在所述第一类型的PUSCH的传输时间单元内传输时,所述UE确定所述第一类型的PUSCH的传输时间单元内没有传输所述第二类型的PUSCH的时间段内所述第一类型的PUSCH的实际发送功率为第一功率，其中，第二类型的PUSCH可以是用于传输高优先级的时延要求较高的业务，例如URLLC业务，而且所述第一类型的PUSCH的传输时间单元的长度大于所述第二类型的PUSCH的传输时间单元的长度，也就是说，在第一类型的PUSCH的传输时间单元内并不是一直都有第二类型的PUSCH在同时传输，此时的第一功率即第一类型的PUSCH与第二类型的PUSCH没有在同一时间段内同时传输时第一类型的PUSCH的实际发送功率，第一功率要要大于或等于所述初始发送功率且小于或等于所 述UE用于传输PUSCH的最大功率；
当有第二类型的PUSCH需要在所述第一类型的PUSCH的传输时间单元内传输时,所述UE确定所述第一类型的PUSCH的传输时间单元内用于传输所述第二类型的PUSCH的时间段内所述第一类型的PUSCH的实际发送功率为第二功率,此时的第二功率即第一类型的PUSCH与第二类型的PUSCH在同一时间段内同时传输时第一类型的PUSCH的实际发送功率，其中,所述第二功率大于或等于0，且所述第二功率与所述第二类型的PUSCH的发送功率相加之和小于或等于所述UE用于传输PUSCH的最大功率，其中，第二类型的PUSCH的发送功率可以根据3GPP TS 38.213标准中规定的公式可以计算得到。
本申请实施例中，在第一类型的PUSCH的传输时间单元内，无论是只有第一类型的PUSCH进行传输的时间段，还是第一类型的PUSCH与第二类型的PUSCH同时传输的时间段，UE的总传输功率都不会超过UE用于传输PUSCH的最大功率，使得接收端可以正常接收信号。
结合本申请实施例第一方面，本申请实施例第一方面的第一种实施方式中，所述第一功率等于所述第二功率与所述第二类型的PUSCH的发送功率相加之和。
通过本申请实施例提供的方案，无论是第一类型的PUSCH与第二类型的PUSCH没有在同一时间段内同时传输时，还是第一类型的PUSCH与第二类型的PUSCH在同一时间段内同时传输时，UE总的传输功率是相等的，即UE在第一类型的PUSCH的传输时间单元内传输时的功率保持恒定，对于一些不支持在一个传输时间单元内发送功率出现跳变的UE来说，保证了UE可以正常传输业务。
结合本申请实施例第一方面，本申请实施例第一方面的第二种实施方式中，所述第二功率与所述第二类型的PUSCH的发送功率相加之和与所述第一功率的差值小于或等于预设差值。
结合本申请实施例第一方面的第二种实施方式，本申请实施例第一方面的第三种实施方式中，所述预设差值为所述UE所支持的同一传输时间单元内的任意两个非零发送功率之差的最大值。
通过本申请实施例提供的方案，在第一类型的PUSCH与第二类型的PUSCH没有在同一时间段内同时传输时，以及第一类型的PUSCH与第二类型的PUSCH在同一时间段内同时传输时，UE允许总的传输功率不必要一直保持恒定，也就是说，UE分别在两个时间段的传输功率只要保证变化不超出预设差值即可，提高了本方案的可实现性。
结合本申请实施例第一方面，本申请实施例第一方面的第四种实施方式中，所述第一功率等于所述初始发送功率。
通过本申请实施例提供的方案，当第一类型的PUSCH的初始发送功率大于第二类型的PUSCH的发送功率时，UE可以设置第一功率与所述初始发送功率相等，这样实际上也就是在第一类型的PUSCH与第二类型的PUSCH没有在同一时间段内同时传输时可以不改变所述初始发送功率，不用去再次设置第一类型的PUSCH的发送功率。
结合本申请实施例第一方面，本申请实施例第一方面的第五种实施方式中，所述第一功率大于或等于所述第二类型的PUSCH的发送功率。

具体实施方式
本申请实施例提供了一种功率控制方法、相关装置及产品，用于使接收端可以正常接收信号。
本申请主要应用的系统架构或者场景如图1所示，包括接入网设备和终端设备。接入网设备和终端设备均可以工作在许可频段或免许可频段上的基站和终端设备。无论是许可频段，还是免许可频段，在本申请中，都可以包括一个或多个载波，许可频段和非许可频段进行载波聚合，可以包括许可频段包括的一个或多个载波与非许可频段包括的一个或多个载波进行载波聚合。
接入网设备可以是长期演进(long term evolution，LTE)系统或者授权辅助接入长期演进(authorized auxiliary access long-term evolution，LAA-LTE)系统中的演进型基站(evolutional Node B，简称可以为eNB或e-NodeB)、宏基站、微基站(也称为“小基站”)、微微基站、接入站点(access point，AP)、传输站点(transmission point，TP)或新空口(new radio，NR)系统中的基站，例如，新一代基站(new generation Node B，gNodeB)等。
终端设备可称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal)、智能终端等，该终端设备可以经无线接入网(radio access network，RAN)与一个或多个核心网进行通信。例如，终端设备可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等，终端设备还可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置以及未来NR网络中的终端设备，它们与无线接入网交换语音或数据。对终端设备的说明：本申请中，和基站可以进行数据通信的都可以看为终端设备，本申请中将以一般意义上的UE来介绍。
未来5G无线通信主要包括eMBB、URLLC和mMTC三种应用场景，传输URLLC业务与eMBB业务时通常采用具有不同大小的传输时间单元。为便于理解，在本申请中将传输URLLC业务的PUSCH的传输时间单元简称为URLLC业务的传输时间单元，将传输eMBB业务的PUSCH的传输时间单元的简称为eMBB业务的传输时间单元。URLLC业务的传输时间单元通常小于eMBB业务的传输时间单元，由于业务特性的不同，URLLC业务与eMBB业务的功率控制参数 通常相互独立。
UE可以按照3GPP TS 38.213标准中规定的公式计算UE在服务小区的载波上传输PUSCH所使用的传输功率，公式如下：
Figure PCTCN2019073325-appb-000001
其中，c表示服务小区，f表示载波，i表示PUSCH的传输时间单元的编号，j表示使用的参数配置集合，j为参数组(参数组包如下参数中的至少一种：P O_PUSCH,f,c(j)和α f,c(j))的索引或者编号，j的不同取值表示不同的参数组，不同类型的PUSCH(例如，基于动态调度的PUSCH、基于免授权传输(transmission without grant/Grant-free transmission)的PUSCH)对应的参数组可以对应j的不同取值，q d表示确定用于计算路径损耗的参考信号的参数，l表示功控调整进程索引，P CMAX,f,c(i)是配置给UE在服务小区的载波上的传输时间单元内的最大传输功率，μ与所使用的子载波间隔Δf有关，μ＝log2(Δf/15KHz)，
Figure PCTCN2019073325-appb-000002
是分配给UE的用于传输PUSCH的带宽，以资源块(Resource Block，RB)表示，P O_PUSCH,f,c(j)表示PUSCH期望的目标功率值，由高层信令配置，α f,c(j)表示路径损耗补偿因子，由高层信令配置，PL f,c(q d)表示由参数q d指示的参考信号估计的路径损耗，Δ TF,f,c(i)表示调制编码方式对应的功率偏移量，f f,c(i,l)表示闭环功率控制调整量，该公式计算得到的功率的单位是dBm。一种可能的实现中，基站可以通过下发消息给UE以通知其使用哪一个参数组来计算PUSCH的发送功率，例如，通过下行控制信息中探测参考信号(Sounding Reference Signal，SRS)的资源指示(SRS resource indicator，SRI)域来通知UE使用哪一个参数组，即通过SRI域的内容来确定j的取值。
可以理解的是，基站向UE下发的SRI可以指示不同的P O_PUSCH,f,c(j)及α f,c(j)，因此，分别计算URLLC业务与eMBB业务的传输功率可以使用不同的参数组，即两种业务会根据标准中的功率控制公式以及自己的功率控制参数，独立计算各自的传输功率。在一种可能实现的方式，上述参数组可以是基站通知给所述UE的。
可以理解的是，两种类型的PUSCH会根据标准中的功率控制公式以及自己的功率控制参数，独立计算各自的传输功率，那么两种类型的PUSCH各自的传输功率都不会超过UE用于传输PUSCH的最大传输功率，而当UE需要同时传输这两种类型的PUSCH时，就有可能出现UE当前的发送总功率超过了UE用于传输PUSCH的最大传输功率，具体可以如图2所示，横坐标表示时间，纵坐标表示功率，以两种类型的PUSCH分别为eMBB业务和URLLC业务为 例，eMBB业务的传输时间单元要大于URLLC业务的时间传输单元，在eMBB业务的传输时间单元内一开始没有URLLC业务的传输，此时UE的传输总功率就是eMBB业务的发送功率，不会超过UE的最大传输功率，之后在eMBB业务的传输时间单元内同时有URLLC业务传输时，UE的传输总功率就等于eMBB业务的发送功率加上URLLC业务的发送功率，有可能超过UE的最大传输功率，会影响接收端对信号的正常接收。
为此本申请实施例中提供了一种功率控制方法以解决上述问题，为便于理解，下面对本申请实施例中的具体流程进行描述：
具体在本申请实施例中，以第一类型的PUSCH传输的业务为eMBB业务，第二类型的PUSCH传输的业务为URLLC业务为例进行说明，那么可以理解的是，第一类型的PUSCH的传输时间单元为eMBB业务的传输时间单元，第二类型的PUSCH的传输时间单元为URLLC业务的传输时间单元，eMBB业务与URLLC业务在频域上是否有重叠在此不做限定，并且本申请实施例中提供的功率控制方法可以基于动态调度，也可以是基于半静态调度，也可以是基于免授权传输，此外，开环功率控制和闭环功率控制在本申请实施例中均可适用。
请参阅图3，本申请实施例中功率控制方法的一个实施例包括：
301、UE确定eMBB业务的初始发送功率。
本申请实施例中，UE可以根据3GPP TS 38.213标准中规定的公式计算出第一类型的PUSCH的初始发送功率，该初始发送功率可以如
Figure PCTCN2019073325-appb-000003
所示，也就是按照标准中规定的UE在eMBB业务的传输时间单元内传输eMBB业务的功率。
302、UE确定eMBB业务的传输时间单元内没有传输URLLC业务的时间段内eMBB业务的实际发送功率为第一功率。
本申请实施例中，由于URLLC业务的传输时间单元小于eMBB业务的传输时间单元，那么在有URLLC业务需要在eMBB业务的传输时间单元内传输时，可以将eMBB业务的传输时间单元分为两个时间段，一个时间段是只有eMBB业务进行传输的时间段，另一时间段是eMBB业务与URLLC业务同时传输的时间段，在只有eMBB业务进行传输的时间段内UE确定当前eMBB业务的实际发送功率为第一功率，其中，第一功率要大于或等于eMBB业务的初始发送功率且小于或等于UE用于传输PUSCH的最大功率。
303、UE确定eMBB业务的传输时间单元内用于传输URLLC业务的时间段内eMBB业务的实际发送功率为第二功率。
本申请实施例中，在eMBB业务与URLLC业务同时传输的时间段内UE确定当前eMBB业务的实际发送功率为第二功率，其中，第二功率与URLLC业务的发送功率相加之和要小于或等于UE用于传输PUSCH的最大功率，URLLC业务的发送功率可以如
Figure PCTCN2019073325-appb-000004
所示，也就是按照标准中规定的UE在URLLC业务的传输时间单元内传输URLLC业务的功率。
可以理解的是，在本申请实施例中，UE要保证在eMBB业务的传输时间单元内URLLC业务的发送功率保持不变而只调整eMBB业务的发送功率。
本申请实施例中，在eMBB业务的传输时间单元内，无论是只有eMBB业务进行传输的时间段，还是eMBB业务与URLLC业务同时传输的时间段，UE的总传输功率不会超过UE用 于传输PUSCH的最大功率，使得接收端可以正常接收信号。
需要说明的是，本申请实施例具体可以有多种实现方式，下面分别进行说明：
方案一：UE确定第一功率等于第二功率与URLLC业务的发送功率相加之和。
具体地，方案一又可以有两种实现方式，下面分别进行说明：
1、eMBB业务的初始发送功率分别乘以不同的系数计算得到第一功率和第二功率。
本申请实施例中，首先根据标准中的公式计算出eMBB业务的初始发送功率
Figure PCTCN2019073325-appb-000005
及URLLC业务的发送功率
Figure PCTCN2019073325-appb-000006
为了保证第一功率等于第二功率与URLLC业务的发送功率相加之和，那么第一功率必须大于或等于URLLC业务的发送功率，首先确定计算第一功率需要的第一系数，具体可以如以下条件所示：
Figure PCTCN2019073325-appb-000007
其中，w(i 2)为计算第一功率的第一系数。
可以看出，确定w(i 2)可以分为两种情况，当eMBB业务的初始发送功率大于或等于URLLC业务的发送功率时，确定w(i 2)＝1，即此时第一功率等于eMBB业务的初始发送功率，而当eMBB业务的初始发送功率小于URLLC业务的发送功率时，就需要放大eMBB业务的初始发送功率得到第一功率，即此时w(i 2)>1，并且还要保证第一功率大于或等于URLLC业务的发送功率。
也就是，第一功率要满足如下条件：
Figure PCTCN2019073325-appb-000008
其中，
Figure PCTCN2019073325-appb-000009
即第一功率。
计算得到了第一功率，用第一功率减去URLLC业务的发送功率就可以得到第二功率。
也就是，第二功率要满足如下条件：
Figure PCTCN2019073325-appb-000010
其中，
Figure PCTCN2019073325-appb-000011
即第二功率，那么
Figure PCTCN2019073325-appb-000012
v(i 2)为计算第二功率的第二系数。
基于以上的方式就可以分别计算得到w(i 2)及v(i 2)这两个系数。
2、通过比较eMBB业务的初始发送功率与URLLC业务的发送功率来确定第一功率及第二功率。
本申请实施例中，首先根据标准中的公式计算出eMBB业务的初始发送功率
Figure PCTCN2019073325-appb-000013
及URLLC业务的发送功率
Figure PCTCN2019073325-appb-000014
然后比较
Figure PCTCN2019073325-appb-000015
与
Figure PCTCN2019073325-appb-000016
的大小，如果
Figure PCTCN2019073325-appb-000017
大于或等于
Figure PCTCN2019073325-appb-000018
那么第一功率就等于
Figure PCTCN2019073325-appb-000019
如果
Figure PCTCN2019073325-appb-000020
小于
Figure PCTCN2019073325-appb-000021
那么第一功率就等于
Figure PCTCN2019073325-appb-000022
进而，在
Figure PCTCN2019073325-appb-000023
大于或等于
Figure PCTCN2019073325-appb-000024
的条件下，第二功率就等于第一功率减去
Figure PCTCN2019073325-appb-000025
在
Figure PCTCN2019073325-appb-000026
小于
Figure PCTCN2019073325-appb-000027
的条件下，第二功率就等于0，即停止发送eMBB业务。
为便于理解，请参阅图4，横坐标表示时间，纵坐标表示功率，以两种类型的PUSCH分别为eMBB业务和URLLC业务为例，eMBB业务的传输时间单元要大于URLLC业务的时间传输单元，在eMBB业务的传输时间单元内一开始没有URLLC业务的传输，此时UE的传输总功率就是第一功率，可以看出第一功率大于URLLC的发送功率且不会超过UE的最大传输功率，之后在eMBB业务的传输时间单元内同时有URLLC业务传输时，UE的传输总功率就等于第二功率加上URLLC业务的发送功率，并且此时UE的传输总功率仍等于第一功率，也就是在eMBB业务的传输时间单元内UE的传输总功率保持恒定，对于一些不支持在一个传输时间单元内发送功率出现跳变的UE来说，保证了UE可以正常传输业务，并且接收信号的相位是连续的，不会影响接收端的解调性能。
方案二：UE确定第二功率与第二类型的PUSCH的发送功率相加之和与第一功率的差值小于或等于预设差值，该预设差值是UE所支持的同一传输时间单元内的任意两个非零发送功率之差的最大值。
具体地，方案二又可以有两种实现方式，下面分别进行说明：
1、eMBB业务的初始发送功率分别乘以不同的系数计算得到第一功率和第二功率。
本申请实施例中，首先根据标准中的公式计算出eMBB业务的初始发送功率
Figure PCTCN2019073325-appb-000028
及URLLC业务的发送功率
Figure PCTCN2019073325-appb-000029
还要确定预设差值
Figure PCTCN2019073325-appb-000030
确定第一系数可以如以下条件所示：
Figure PCTCN2019073325-appb-000031
其中，w(i 2)为计算第一功率的第一系数。
可以看出，要确定w(i 2)可以分为两种情况，当eMBB业务的初始发送功率大于或等于URLLC业务的发送功率时，确定w(i 2)＝1，即此时第一功率等于eMBB业务的初始发送功率，而当eMBB业务的初始发送功率小于URLLC业务的发送功率时，此时要保证第一功率加上预设差值大于或等于等于URLLC业务的发送功率。
也就是，第一功率要满足如下条件：
Figure PCTCN2019073325-appb-000032
其中，
Figure PCTCN2019073325-appb-000033
即第一功率。
计算得到了第一功率，就可以根据第一功率、URLLC业务的发送功率及预设差值来计算第二功率。
也就是，第二功率要满足如下条件：
Figure PCTCN2019073325-appb-000034
其中，
Figure PCTCN2019073325-appb-000035
即第二功率，那么
Figure PCTCN2019073325-appb-000036
v(i 2)为计算第二功率的第二系数，当第一功率与预设差值相加等于URLLC业务的发送功率时，v(i 2)等于0，即此时停止发送eMBB业务。
2、通过比较eMBB业务的初始发送功率与URLLC业务的发送功率来确定第一功率及第二功率。
本申请实施例中，首先根据标准中的公式计算出eMBB业务的初始发送功率
Figure PCTCN2019073325-appb-000037

然后比较

与

的大小，如果
Figure PCTCN2019073325-appb-000041
大于或等于

那么第一功率就等于

如果
Figure PCTCN2019073325-appb-000044
小于
Figure PCTCN2019073325-appb-000045
那么第一功率就等于URLLC业务的发送功率减去预设差值。
进而，在
Figure PCTCN2019073325-appb-000046
大于或等于
Figure PCTCN2019073325-appb-000047
的条件下，第二功率等于第一功率减去URLLC业务的发送功率与预设差值的和，在

小于
Figure PCTCN2019073325-appb-000049
的条件下，第二功率就等于0，即停止发送eMBB业务。
为便于理解，请参阅图5，横坐标表示时间，纵坐标表示功率，以两种类型的PUSCH分别为eMBB业务和URLLC业务为例，eMBB业务的传输时间单元要大于URLLC业务的时间传输单元，在eMBB业务的传输时间单元内一开始没有URLLC业务的传输，此时UE的传输总功率就是第一功率，可以看出第一功率大于URLLC的发送功率且不会超过UE的最大传输功率，之后在eMBB业务的传输时间单元内同时有URLLC业务传输时，UE的传输总功率就等于第二功率加上URLLC业务的发送功率，且第一功率减去第二功率与URLLC业务的发送功率的和等于预设差值。
又或者如图6所示，横坐标表示时间，纵坐标表示功率，以两种类型的PUSCH分别为eMBB业务和URLLC业务为例，eMBB业务的传输时间单元要大于URLLC业务的时间传输单元，在eMBB业务的传输时间单元内一开始没有URLLC业务的传输，此时UE的传输总功率就是第一功率，可以看出第一功率小于URLLC的发送功率且URLLC的发送功率不会超过UE的最大传输功率，之后在eMBB业务的传输时间单元内同时有URLLC业务传输时，UE的传输总功率就等于URLLC业务的发送功率，即停止发送eMBB业务，而且URLLC业务的发送功率减去第一功率等于预设差值。
本申请实施例中，在eMBB业务的传输时间单元内，无论是只有eMBB业务进行传输的时间段，还是eMBB业务与URLLC业务同时传输的时间段，UE允许总的传输功率不必要一直保持恒定，也就是说，UE分别在两个时间段的传输功率只要保证变化不超出预设差值即可，提高了本方案的可实现性。
方案三：eMBB业务的传输时间单元内，在只有eMBB业务进行传输的时间段，UE确定第一功率等于eMBB业务的初始发送功率，在eMBB业务与URLLC业务同时传输的时间段，UE确定第二功率与URLLC业务的发送功率相加之和小于或等于UE用于传输PUSCH的最大功率。
具体地，方案三又可以有两种实现方式，下面分别进行说明：
1、在只有eMBB业务进行传输的时间段，保持eMBB业务的初始发送功率不变，即第一功率等于eMBB业务的初始发送功率，在eMBB业务与URLLC业务同时传输的时间段，eMBB业务的初始发送功率乘以系数得到第二功率，使第二功率与URLLC业务的发送功率相加之和小于或等于UE用于传输PUSCH的最大功率。
本申请实施例中，首先根据标准中的公式计算出eMBB业务的初始发送功率

及URLLC业务的发送功率
Figure PCTCN2019073325-appb-000051
在只有eMBB业务进行传输的时间段，UE确定第一功率等于eMBB业务的初始发送功率。
在eMBB业务与URLLC业务同时传输的时间段，第二功率需要满足如下条件：

2、在只有eMBB业务进行传输的时间段，保持eMBB业务的初始发送功率不变，即第一 功率等于eMBB业务的初始发送功率，在eMBB业务与URLLC业务同时传输的时间段，第二功率等于UE用于传输PUSCH的最大功率减去URLLC业务的发送功率。
本申请实施例中，首先根据标准中的公式计算出eMBB业务的初始发送功率

及URLLC业务的发送功率
Figure PCTCN2019073325-appb-000055
在只有eMBB业务进行传输的时间段，UE确定第一功率等于eMBB业务的初始发送功率。
在eMBB业务与URLLC业务同时传输的时间段，第二功率需要满足如下条件：
Figure PCTCN2019073325-appb-000056
可以看出，第二功率等于UE用于传输PUSCH的最大功率减去URLLC业务的发送功率。
为便于理解，请参阅图7，横坐标表示时间，纵坐标表示功率，以两种类型的PUSCH分别为eMBB业务和URLLC业务为例，eMBB业务的传输时间单元要大于URLLC业务的时间传输单元，在eMBB业务的传输时间单元内一开始没有URLLC业务的传输，此时UE的传输总功率就是第一功率，并且第一功率等于eMBB业务的初始发送功率，之后在eMBB业务的传输时间单元内同时有URLLC业务传输时，UE的传输总功率就等于第二功率加上URLLC业务的发送功率，为了保证此时UE的传输总功率不超过UE用于传输PUSCH的最大功率，UE将用于传输eMBB业务的第一功率缩减为第二功率，这种功率控制方法适用于支持在一个传输时间单元内发送功率出现跳变的UE，也就是可以不用保证在eMBB业务的传输时间单元内UE的传输总功率保持在恒定的状态，只需要在在eMBB业务与URLLC业务同时传输的时间段对eMBB业务的传输功率进行调整，即确定第二功率，在在只有eMBB业务进行传输的时间段仍保持eMBB业务的初始发送功率，减少了UE在eMBB业务的传输时间单元内对eMBB业务进行功率控制的次数，降低了能耗。
上面对申请实施例中的功率控制方法的具体实施方式进行了描述，此外，基于以上描述的功率控制方法，本申请实施例还可以根据UE自身的能力信息来选择上述相应的功率控制方法，需要说明的是，本申请实施例具体可以有多种实现方式，下面分别进行说明：
1、UE根据自身的能力信息选择相应的功率控制方法。
请参阅图8，本申请实施例中功率控制方法的另一个实施例包括：
801、UE获取自身的能力信息。
本申请实施例中，UE可以获取自身的能力信息，该能力信息用于指示自身是否支持在一个传输时间单元内有多种发送功率，也就是说，根据能力信息可以获知在一个传输时间单元内UE是否允许自身的发送功率出现超过一定幅度的跳变。
802、UE判断自身是否支持在一个传输时间单元内有多种发送功率，若否，则执行步骤803。
本申请实施例中，UE在获取到自身的能力信息后，可以根据该能力信息判断自身是否支持在一个传输时间单元内有多种发送功率。
803、UE采用方案一或方案二的功率控制方法。
本申请实施例中，当UE确定自身不支持在一个传输时间单元内有多种发送功率时，UE 可以选择采用上述功率控制方法中方案一或方案二所述的功率控制方法，可以理解的是，在一个传输时间单元内UE不能允许自身的发送功率出现超过一定幅度的跳变，那么就需要保证一个传输时间单元内UE的传输总功率维持在一个相对恒定的范围内，根据上述提供的方案一、方案二及方案三的三种功率控制方法可知，UE需要采用方案一或方案二的功率控制方法。
需要说明的是，如果UE确定自身支持在一个传输时间单元内有多种发送功率时，那么UE可以选择采用上述方案一、方案二及方案三的三种功率控制方法中的任意一种，具体选择哪一种功率控制方法，此处不做限定。
2、UE向网络设备上报自身的能力信息，由网络设备根据该能力信息指示UE选择相应的功率控制方法。
请参阅图9，本申请实施例中功率控制方法的另一个实施例包括：
901、UE获取自身的能力信息。
本申请实施例中，步骤901与图8所示的实施例中的步骤801类似，具体此处不再赘述。
902、UE向网络设备发送自身的能力信息。
本申请实施例中，UE在获取到自身的能力信息后会将该能力信息上报至网络设备。
903、UE接收网络设备发送的功率计算模式信息并确定功率控制方法。
本申请实施例中，网络设备在收到UE上报的自身的能力信息后，网络设备可以生成功率计算模式信息并反馈给UE，也就是网络设备通过该功率计算模式信息告知UE采用哪种功率控制方法，例如，网络设备根据UE自身的能力信息确定该UE不支持在一个传输时间单元内有多种发送功率，那么，网络设备就可以通过该功率计算模式信息告知UE采用上述方案一或方案二的功率控制方法，如果网络设备根据UE自身的能力信息确定该UE支持在一个传输时间单元内有多种发送功率，那么，网络设备就可以通过该功率计算模式信息告知UE采用上述方案一、方案二或方案三种任意的一种功率控制方法，具体采用哪种功率控制方法此处不做限定。
本申请实施例中，UE可以根据自身的能力信息来确定相应的功率控制方法，提高了本方案的灵活性。
上面对本申请实施例中的功率控制方法进行了描述，下面对本申请实施例中的UE进行描述：
请参阅图10，本申请实施例中UE的一个实施例包括：
第一确定单元1001、用于确定第一类型的物理上行共享信道PUSCH的初始发送功率；
第二确定单元1002、用于当有第二类型的PUSCH需要在所述第一类型的PUSCH的传输时间单元内传输时,确定所述第一类型的PUSCH的传输时间单元内没有传输所述第二类型的PUSCH的时间段内所述第一类型的PUSCH的实际发送功率为第一功率,其中,所述第一类型的PUSCH的传输时间单元的长度大于所述第二类型的PUSCH的传输时间单元的长度,所述第一功率大于或等于所述初始发送功率且小于或等于所述UE用于传输PUSCH的最大功率；
第三确定单元1003、用于当有第二类型的PUSCH需要在所述第一类型的PUSCH的传输 时间单元内传输时,确定所述第一类型的PUSCH的传输时间单元内用于传输所述第二类型的PUSCH的时间段内所述第一类型的PUSCH的实际发送功率为第二功率,其中,所述第二功率大于或等于0，且所述第二功率与所述第二类型的PUSCH的发送功率相加之和小于或等于所述UE用于传输PUSCH的最大功率。
可选地，该第二确定单元1002可以执行如上述方案一、方案二及方案三的功率控制方法中确定第一功率的步骤，具体此处不再赘述。
可选地，该第三确定单元1003可以执行如上述方案一、方案二及方案三的功率控制方法中确定第二功率的步骤，具体此处不再赘述。
可选地，该UE还可以包括：
发送单元1004、用于向网络设备发送自身的能力信息，其中，所述能力信息用于指示在同一个传输时间单元内所述UE是否支持多种发送功率。
接收单元1005、用于接收所述网络设备发送的功率计算模式信息，其中，所述功率计算模式信息用于确定所述第一功率及所述第二功率的确定方法。
本申请实施例中，第一确定单元1001确定第一类型的PUSCH的初始发送功率，当有第二类型的PUSCH需要在所述第一类型的PUSCH的传输时间单元内传输时,第二确定单元1002确定所述第一类型的PUSCH的传输时间单元内没有传输所述第二类型的PUSCH的时间段内所述第一类型的PUSCH的实际发送功率为第一功率,其中,所述第一类型的PUSCH的传输时间单元的长度大于所述第二类型的PUSCH的传输时间单元的长度,所述第一功率大于或等于所述初始发送功率且小于或等于所述UE用于传输PUSCH的最大功率，当有第二类型的PUSCH需要在所述第一类型的PUSCH的传输时间单元内传输时,第三确定单元1003确定所述第一类型的PUSCH的传输时间单元内用于传输所述第二类型的PUSCH的时间段内所述第一类型的PUSCH的实际发送功率为第二功率,其中,所述第二功率大于或等于0，且所述第二功率与所述第二类型的PUSCH的发送功率相加之和小于或等于所述UE用于传输PUSCH的最大功率，可以看出，在第一类型的PUSCH的传输时间单元内，无论是只有第一类型的PUSCH进行传输的时间段，还是第一类型的PUSCH与第二类型的PUSCH同时传输的时间段，UE的总传输功率都不会超过UE用于传输PUSCH的最大功率，使得接收端可以正常接收信号，此外发送单元1004可以向网络设备发送自身的能力信息，其中，所述能力信息用于指示在同一个传输时间单元内所述UE是否支持多种发送功率，之后，接收单元1005可以接收所述网络设备发送的功率计算模式信息，其中，所述功率计算模式信息用于确定所述第一功率及所述第二功率的确定方法，UE可以根据自身的能力信息来确定相应的功率控制方法，提高了本方案的灵活性。
