长期演进系统(Long Term Evolution，LTE)的功率分配的具体实现方式可以是：
终端设备在接收到基站分配的上行资源后，会计算出利用该上行资源发送数据的功率。
如果在一定的时间区域上激活服务小区的资源上的功率之和大于UE的最大输出功率，那么此时则需要进行功率调整。即通过信道的功率因子来调整某些信道的资源对应的功率，确保在一定的时间区域上的功率不会大于UE的最大输出功率。具体调整功率的规则是：针对不同的信道设置不同的功率因子来调节资源的功率，但是针对信道内资源，则不存在具体的功率调节机制，使得同一信道的不同需求的业务功率分配不合理，从而导致一些业务需求没办法满足，并且导致利用这些资源进行数据传输的时延加大可靠性降低。

具体实施方式
为了更清楚详细的说明本发明所提供方案的具体实现过程，以下结合具体的实例对本申请实施例所提供的方法做进一步详细的说明：
本申请所提供的方法实现基于资源的功率调整，而且可以实现单一物理信道(或信号)以及多物理信道(或信号)的功率调整。其中，物理信道可以包括：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)、物理随机接入信道(Physical random access channel，PRACH)；因为本申请所提供的方案是针对不同的业务需求进行功率分配，则基于该原理本申请实施例中所提到的物理信道也可以解释为物理信号，其中，该物理信号可以是：探测参考信号(sounding reference signal，SRS)。
为了更清楚详细的说明本申请所提供的方法，以下分别以单一物理信道或多物理信道为例对本申请的方案做进一步说明。
实施例一
针对单一物理信道或信号，如图1所示，本申请实施例提供一种功率控制方法，该方法具体可以包括以下实现步骤：
步骤101，终端设备确定至少两份资源，所述至少两份资源在时域上存在第一重叠区域，所述至少两份资源每一份在所述第一重叠区域对应一个第一功率；
在本申请实施例中，确定至少两份资源的方式可以是：
A1，终端设备接收网络设备的至少一个指示；
终端设备接收该指示的方式可以是：通过无线资源控制(Radio Resource Control，RRC)接收该指示，和/或，通过下行控制信令(Downlink Control Information，DCI)接收该指示。
A2，所述至少一个指示用于分配至少两份资源，所述至少两份资源用于进行至少两份数据的上行传输。
该实施例中，所述至少两份资源是至少一个小区的资源，并且该至少两份资源可以包括以下至少一种类型的资源：时域资源、时频资源、基于波束(beam)的时频资源、基于空口格式的时频资源、用于终端与终端(D2D)通信的无线资源和用于终端与网络设备通信的无线资源、用于正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)的无线资源、用于单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)的无线资源、基于竞争的时频资源。其中，空口格式为子载波间隔和循环前缀的参数集合，比如通过命理(numerology)参数来设定。
可选的，如图2所示，该实施例中第一重叠区域是指图2中重叠区域所对应的第一时域所对应的部分，而且确定第一时域的值大于一个设定的门限则可以确定第一时域所对应的区域为重叠区域。终端设备在小区1的第一时域确定一个第一功率；在小区2的第一时域确定另外一个第一功率；如果小区1和小区2在第一时域所对应的第一功率之和大于最大功率，即本申请实施例所针对的功率控制场景。
步骤102，若所述至少两份资源对应同一种物理信道，并且所述至少两份资源在所述第一重叠区域对应的第一功率之和大于最大功率(该最大功率可以是终端设备在重叠区域的最大输出功率)，所述终端设备根据所述至少两份资源每一份的优先级确定所述至少两份资源每一份的功率因子；其中，基于所述功率因子将所述至少两份资源中每一份在所述重叠区域的第一功率进行调整后的功率之和小于或等于所述最大功率，并且所述至少两份 资源中优先级高的资源的功率因子大，优先级低的资源的功率因子小。
当第一重叠区域的功率之和大于最大功率，则需要进行功率调整(或称为功率调整)，具体的调整方式可以是对第一功率进行扩大、缩小或保持不变。如果要实现保持不变可以调整其他资源所对应的发送功率来实现总体发送功率不超过最大功率，具体其他资源可以包括其他激活服务小区的用于所述终端设备的上行传输的资源，或，本小区的其他TTI长度的用于所述终端设备的上行传输的资源。其中，最大功率还可以理解为最大输出功率，比如UE最大输出总功率的线性值(the linear value of the UE total configured maximum output power)。
可选地，所述功率因子的范围可以是大于等于0，在调整好第一功率后，终端设备则可以基于调整后的功率进行数据发送，具体实现可以是：
步骤103，所述终端设备使用所述至少两份资源每一份的功率因子分别对每一份资源进行功率调整；并按照每一份资源调整后的功率向无线接入设备发送数据。
可选的，本申请实施例中至少两份资源的优先级可以是协议预先规定的，或，是由网络设备预先配置的。另外，该实施例提供的优先级可以通过多个维度的参数进行确定，具体可以包括：
第1种，基于资源的传输时间间隔(Transmission Time Interval，TTI)和/或子载波间隔确定资源的优先级，具体可以是：
所述至少两份资源的TTI长度(TTI长度还可以理解为所述资源的时域资源的时长)越短的优先级越高；和/或
所述至少两份资源的子载波间隔越窄的优先级越高。
该实施例中，TTI长度的优先级和子载波间隔的优先级组合使用的时候，可以是先确定TTI长度的优先级然后再确定子载波间隔的优先级，反之亦然。具体的，在所述至少两份资源中，对于同一TTI长度，子载波间隔窄的资源优先级高，子载波间隔宽的资源优先级低；或在所述至少两份资源中，对于同一子载波间隔，TTI长度短的资源优先级高，TTI长度长的资源优先级低。
在具体的应用环境中如果使用基于TTI长度的优先级，如图2所示小区1(Cell1)和小区2(Cell2)，基站在这两个小区都分配了上行资源，其中，Cell1的上行资源的TTI长度为1ms，Cell2的上行资源的TTI长度为0.5ms。在两份上行资源中的重叠区域，终端设备针对两个上行传输确定的第一功率之和大于最大输出功率，此时就需要功率调整，以保证发送功率的要求。由于Cell2的TTI较短，一般情况下TTI较短的资源上承载的数据的服务质量(Quality of Service，QoS)要求较高，所以终端设备优先保证Cell2的数据传输。如果还有剩余功率，此时将剩余功率分配功率给Cell1的数据传输。如图3所示。
具体实现可以是，终端设备最开始Cell1的发送功率为P1，其中P1小于最大输出功率Pcmax，由于Cell2的上行传输导致功率不足，也就是P1+P2大于Pcmax，从而进行功率调整，Cell1的发送功率从P1减为P1`，Cell2的发送功率为P2，其中P2+P1`＝Pcmax.。
可选地，对于物理信道为控制信道，控制信道可能用于传输信道状态信息(channel state information，CSI)/调度请求(scheduling request，SR)/混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)反馈。为了针对时延敏感和不敏感的下行数据的业务需求，根据PUCCH多对应的TTI长度可以将PUCCH分为一种短的PUCCH和长的PUCCH，用于HARQ反馈，所述短的PUCCH只需占用一个或几个OFDM或SC-FDMA符号，长的PUCCH 比短PUCCH占用的资源的时长更长，比如在同一种numerology的场景下占用的OFDM或SC-FDMA符号数多，可以用于传输CSI/SR/HARQ反馈(时延不敏感的下行数据)，如果长PUCCH和短PUCCH同传，那么优先短PUCCH的功率分配，在还有剩余功率的情况，可分配剩余功率用于长PUCCH的数据传输。下面罗列的可能，至少满足以下至少一种：
1.短PUCCH的HARQ反馈>长PUCCH的HARQ反馈
2.短PUCCH的CSI>长PUCCH的CSI
3.短PUCCH的SR>长PUCCH的SR
4.短PUCCH的HARQ反馈>长PUCCH的CSI
5.短PUCCH的HARQ反馈>长PUCCH的SR
6.短PUCCH的SR>长PUCCH的CSI
其中CSI信道状态信息，包括以下至少一种：CQI信道质量信息，用于基站选择调制编码方案，更好的利用无线资源；PMI预编码矩阵指示，用于多天线传输。RI秩(层)指示用于多天线传输中。PTI预编码类型指示，用于多天线传输中。HARQ反馈用于通知网络设备下行数据是否被终端设备解码成功。
第2种，通过资源所对应小区的优先级确定，资源的优先级。具体实现可以是：
所述至少两份资源对应不同的小区，则根据预设的小区优先级，所述至少两份资源中资源所对应小区的优先级越高则对应资源的优先级越高。
可选的，如果将小区划分为：
高频小区：工作的频段大于或等于6GHz；
低频小区：工作的频段小于6GHz；
非授权小区：频谱资源是共享的，还可以理解为，可以跟无线保证(wifi)共享的频谱资源。还可以理解为，发送数据前需要进行空闲信道检测的小区，比如，能量检测。能量检测低于门限，则认为空闲，可以发送数据；否则认为忙碌，不可以进行数据发送。
授权小区：相对非授权小区而言，频谱资源是专用的。
在该划分原则可以是低频授权小区的优先级>低频非授权小区的优先级>高频授权小区的优先级>高频非授权小区的优先，具体在比较的时候小区的优先级也可以是以下至少一种：
1.低频授权小区的优先级大于高频授权小区的优先级；
2.低频授权小区的优先级大于高频非授权小区的优先级；
3.低频授权小区的优先级大于低频非授权小区的优先级；
4.低频非授权小区的优先级大于高频非授权小区的优先级；
5.低频非授权小区的优先级大于高频非授权小区的优先级；
6.高频授权小区的优先级大于高频非授权小区的优先级；
7.低频非授权小区的优先级大于高频授权小区的优先级；
8.高频授权小区的优先级大于低频非授权小区的优先级。
可选的，本申请实施例中小区的优先级可以是协议预先规定的，或，是由网络设备预先配置的。
例如，至少两份资源中包括第一资源和第二资源，第一资源对应的小区为低频小区；第二资源对应的小区为高频小区；根据上述小区的优先级原则：对于同一TTI长度的至少 两份资源，低频小区的优先级高于高频小区的优先级，则对应的第一资源的优先级高于第二资源的优先级。
在一些实施例中，小区还可能属于不同的小区组，并且小区组也存在优先级，在该情况下，在确定资源的优先级时，还可以考虑小区组的优先级，具体实现可以是：
所述不同的小区属于不同的小区组，则根据预设的小区组的优先级，所述至少两份资源中资源所对应小区组的优先级越高则对应资源的优先级越高。
可选的，本申请实施例中小区组的优先级可以是协议预先规定的，或，是由网络设备预先配置的。
第一小区组的优先级高于第二小区组，如果第一小区属于第一小区组，第二小区属于第二小区组，第一资源对应第一小区，第二资源对应第二小区，则在确定第一资源和第二资源之间的优先级时，可以选择小区组的优先级或小区的优先级其中一个进行判断，也可以同时判断，如果同时判断小区组的优先级与小区的优先级冲突，则可以预先设置一个判断准则，例如以小区的优先级为最终结果，或以小区组的优先级为最终结果。示例性的，在双连接的场景，第一小区组为主小区组(Master Cell Group，MCG)，第二小区组为辅小区组(Secondary Cell Group，SCG)。
例如，至少两份资源中包括第一资源和第二资源，第一资源对应的小区组为主小区组；第二资源对应的小区组为辅小区组；根据上述小区组的优先级原则：对于同一TTI长度的至少两份资源，主小区组的优先级高于辅小区组的优先级，则对应的第一资源的优先级高于第二资源的优先级。
第3种，通过至少两份资源所对应的媒体接入控制(Media Access Control，MAC)包的优先级确定至少两份资源的优先级，具体实现可以是：
所述终端设备通过MAC层向所述终端设备的物理层通知所述至少两份资源的优先级，其中，该至少两份资源的优先级与所述至少两份资源所对应的MAC包对应。
该实施例中，在MAC层可以基于逻辑信道和TTI长度的映射关系对MAC包进行构造，然后针对构造得到的MAC包则可以通过该MAC包传输的数据对应的逻辑信道或者是TTI长度的优先级确定MAC包的优先级，具体实现可以是：
所述至少两份资源中逻辑信道的优先级高的数据(即MAC包)所使用的资源的优先级高于逻辑信道的优先级低的数据所使用的资源。
第4种，基于资源是否传输数据确定资源的优先级，具体实现可以是：
在时域上，所述至少两份资源中存在第二重叠区域，所述至少两份资源每一份在所述第二重叠区域的第二功率之和大于最大功率；
在所述第二重叠区域上，所述终端设备对所述至少两份资源中未传输完数据的资源使用所述未传输完数据的资源在第一重叠区域上的调整后的功率向无线接入设备发送数据。
可选地，在所述第二重叠区域上，所述终端设备对所述至少两份资源中除去未传输完数据的资源之外的包括所述第二重叠区域的其他资源进行功率调整。即，该实施例中针对至少两份资源进行功率调整时，可以按照重叠区域为单位进行功率调整；如果对第二重叠区域进行功率调整，则只针对包括第二重叠区域的资源进行功率调整。
该实施例的具体实现可以是：在第二重叠区域内，如果至少两份资源的第二功率之和大于最大输出功率，那么至少两份资源中已经使用分配功率进行数据传输的资源，就优先保障进行数据传输的资源的功率分配，至于还没有使用分配的功率的数据，在进行功率调 整时不分配功率。
上述四种资源优先级只是该实施例的一些实现方式，具体实现的时候还可以通过其他方式显示至少两份资源的优先级划分，在此不再赘述。另外，上述优先级描述都是单独实现的，但在具体实现的时候上述各种优先级原则可以组合使用，例如，TTI长度的优先级与子载波间隔的优先级组合使用；可以先判断至少两份资源的TTI长度的优先级，如果TTI长度的优先级相同；则可以再判断子载波间隔的优先级；或可以先判断至少两份资源的子载波间隔的优先级，如果子载波间隔的优先级相同；则可以再判断TTI长度的优先级。
可选的，在基于上述优先级进行资源分配的时，可能会出现非授权小区(Unlicensed cell)/高频小区(HF cell)的TTI长度会很小和/或子载波间隔很大，但是传输的数据对时延和可靠性要求也不高，可以不用优先保障发送功率，可以等同于所述预设优先级中的低优先级。
该实施例中的方案可以是针对不同的小区组设置与小区组对应的基本功率(即每个基站对应有一个基础的保障功率)，具体所述终端设备根据所述至少两份资源每一份的优先级确定所述至少两份资源每一份的功率因子包括：
所述终端设备确定所述至少两份资源所对应小区组的基本功率；
所述终端设备根据所述至少两份资源每一份的优先级和所述基本功率确定所述至少两份资源每一份的功率因子；其中，基于所述功率因子将所述至少两份资源中每一份在所述重叠区域的第一功率进行调整后的功率之和小于或等于所述最大功率，并且每个小区组所对应的功率之和不小于所述每个小区组对应的基本功率。
例如：UE可以跟至少两个基站进行数据通信，为了避免某一个基站无功率可发送，每个基站的小区组会预先配置一个对应的基本功率，如第一基本功率为主基站的小区组的基本保障功率，第二基本功率为辅基站的小区组的基本保障功率。终端设备在重叠区域进行功率分配的时候优先满足第一基本功率和第二基本功率。对于剩余的功率，按照前述各种优先级原则进行功率分配。
实施例二
针对至少两种物理信道，如图4所示，本申请实施例提供一种功率控制方法，该方法具体可以包括以下实现步骤：
步骤401，终端设备确定至少两份资源，所述至少两份资源在时域上存在第一重叠区域，所述至少两份资源每一份在所述第一重叠区域对应一个第一功率；
步骤402，若所述至少两份资源对应至少两种物理信道，并且所述至少两份资源在所述第一重叠区域对应的第一功率之和大于最大功率，所述终端设备根据所述至少两份资源每一份的优先级确定所述至少两份资源每一份的功率因子，和/或，所述终端设备根据所述至少两份资源每一份对应的物理信道的优先级确定所述至少两份资源每一份的功率因子；其中，基于所述功率因子将所述至少两份资源中每一份在所述重叠区域的第一功率进行调整后的功率之和小于或等于所述最大功率，并且所述至少两份资源中优先级高的资源的功率因子大，优先级低的资源的功率因子小。
该实施例中，该至少两种物理信道可以是PUSCH和PUCCH。若物理信道的优先级与至少两份资源的优先级相关联，至少两份资源包括第一资源和第二资源，第一资源对应PUCCH资源，第二资源对应PUSCH资源，第一资源的每一份资源的功率因子之和不小于 第二资源的每一份资源的功率因子之和。对应同一种信道内的功率因子可以根据实施例一的方法进行确定。
因为该实施例方法中的资源可能对应不同的物理信道，所以在进行资源优先级确定的时候还可以参考物理信道的优先级，其中，所述至少两份资源每一份对应的物理信道的优先级包括：随机接入信道的优先级>控制信道的优先级>数据信道优先级。
步骤403，所述终端设备使用所述至少两份资源每一份的功率因子分别对每一份资源进行功率调整；并按照每一份资源调整后的功率向无线接入设备发送数据。
在该实施例中，物理信道的优先级和资源的优先级可以单独使用也可以组合使用，在组合使用的时候可以提前设定先判断信道优先级，然后在判断资源优先级；反之亦然。
以信道PUCCH和PUSCH为例，每一种信道都有两种TTI长度，当物理信道的优先级与资源的优先级组合使用的时候，该实施例所提供的方法可以通过以下两种方式实现至少两份资源的优先级排序，包括：
方式一，资源的优先级优先级的原则，先按TTI长度(TTI长度越短的优先级越高)对至少两份资源进行排序，对于TTI长度一样的资源，则再按信道优先级(如预设的物理信道的优先级是：PUCCH>PUSCH)进行再次排序(排序后的结果如图4A中方式一所示)；
方式二，物理信道的优先级优先级的原则，先按物理信道的优先级(如预设的物理信道的优先级是：PUCCH>PUSCH)进行排序，如果多个资源对应同一种物理信道，则再按TTI长度(TTI长度越短的优先级越高)进行再次排序(排序后的结果如图4A中方式二所示)。
实施例三
如图5所示，上述实施例一和二都在物理层确定各资源的优先级，该实施例还可以在MAC层确定至少两份资源的优先级，具体该实施例提供的一种功率控制方法，包括：
步骤501，终端设备确定至少两份资源，所述至少两份资源在时域上存在第一重叠区域，所述至少两份资源每一份在所述第一重叠区域对应一个第一功率；
步骤502，若所述至少两份资源在所述第一重叠区域对应的第一功率之和大于最大功率，所述终端设备通过MAC层通知的所述至少两份资源的优先级确定所述至少两份资源每一份的功率因子；其中，基于所述功率因子将所述至少两份资源中每一份在所述重叠区域的第一功率进行调整后的功率之和小于或等于所述最大功率，并且所述至少两份资源中优先级高的资源的功率因子大，优先级低的资源的功率因子小。
步骤503，所述终端设备使用所述至少两份资源每一份的功率因子分别对每一份资源进行功率调整；并按照每一份资源调整后的功率向无线接入设备发送数据
在该实施例中，终端设备在MAC层确定资源优先级的方式可以是：
B1，终端设备根据预先配置的逻辑信道与TTI长度的映射关系，进行数据复用和组装所述至少一个MAC包；
例如，逻辑信道1有200bytes数据，可以通过TTI长度1进行传输，逻辑信道2有300bytes数据，可以通过TTI长度1和2进行传输。逻辑信道1的优先级高于逻辑信道2的优先级。基站分配400bytes的TTI长度1的无线资源，该资源的TTI长度为TTI长度1。那么终端设备的MAC层根据该无线资源的逻辑信道与TTI长度的优先级进行资源分配，分配的结果比如：逻辑信道1传输200bytes数据，逻辑信道2传输200bytes数据，剩余100bytes数据，可以留到下次基站分配了新的无线资源之后，才进行数据传输。另外基站 分配了TTI长度2的100bytes上行资源，终端设备的MAC层根据该无线资源和逻辑信道与TTI长度的优先级进行资源分配，分配的结果：逻辑信道2传输100bytes数据。如果TTI长度1和TTI长度2的无线资源在时域上存在重叠区域，那么在重叠区域，由于TTI长度1的资源所传输的数据的逻辑信道的优先级较高，所以终端设备优先分配TTI长度1的资源的功率，在还有剩余功率的情况下，分配TTI长度2的资源的功率。
B2，根据所述至少一个MAC包包括的逻辑信道的数据，确定所述至少一个MAC包的功率优先级。
终端设备的物理层接收终端设备通过MAC层确定的优先级，并根据所述优先级进行功率调整操作。
实施例四
现有技术中，如果终端设备跟至少两个基站进行数据通信，那么主基站为UE配置了1、2号cell，辅基站为UE配置了2、3号cell。但是在上报功率余量报告的时候，UE需要上报所有cell的功率余量。由于主基站和辅基站同时给UE配置了2号cell，但是现有功率余量报告的上报格式不能区分这两个cell，因此上报时会对2号cell产生混淆，基于该现有技术本申请还提供一种功率控制方法，终端设备跟至少两个基站进行数据通信，方法包括：
C1，所述终端设备接收所述至少两个基站的服务小区的小区索引；其中，所述至少两个基站的服务小区的小区索引通过所述至少两个基站通过信令交互协商确定；
在该实施例中，该至少两个基站可以包括主基站和辅基站，主基站和辅基站间可通过信令交互协商终端设备的小区索引，并把协商之后的小区索引的部分或全部通过主基站和/或辅基站发送给终端设备；
C2，所述终端设备根据所述小区索引进行功率余量报告。
可选地，对于终端设备所对应的小区，终端设备还可以接收主基站或辅基站发送的小区激活与去激活命令，并根据所述小区激活与去激活命令中包括小区索引确定所接收到的小区索引所对应的小区中主基站和/或辅基站的那些小区被激活或去激活。
在该实施例中，针对功率余量报告或激活与去激活命令，可以通过协议预先定义不同的字段，用于指示主基站的服务小区的小区索引和辅基站的服务小区的小区索引。终端设备基于协议预先定义不同的字段进行功率余量上报。
实施例五
如图6所示，本申请实施例提供一种功率控制方法，该方法具体可以包括以下实现步骤：
步骤601，终端设备确定至少两份资源，所述至少两份资源在时域上存在第一重叠区域，所述至少两份资源每一份在所述第一重叠区域对应一个第一功率；
所述至少两份资源的每一份资源可用于传输的目标数据包包括：协议数据单元PDU(Protocol Data Unit，协议数据单元)、上行控制信息(UCI，Uplink Control Information)或传输PDU的同时随路上行控制信息；其中，该PDU具体可以是HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)新传的PDU或HARQ重传的PDU。其中，至少一个协议数据单元中的任意一个协议数据单元包括至少一个逻辑信道中部分逻辑信道的数据或全部逻辑信道的数据，可以是HARQ新传数据或HARQ重传数据。所述上行控制信息包括以下任意一种：针对下行数据的ACK/NACK反馈信息，CSI(Channel State Information， 信道状态信息)信息，SR(Scheduling Request，调度请求)信息。所述协议数据单元随路上行控制信息包括了至少一个逻辑信道中部分逻辑信道的数据或全部逻辑信道的数据，可以是HARQ新传数据或HARQ重传数据，也包括了随路的上行控制信息。
所述至少两份资源可以位于不同的服务小区，或，相同的服务小区。所述至少两份资源可以位于相同的物理信道，也可以位于不同的物理信道。例如，用于传输协议数据单元的资源可以位于PUSCH(Physical Uplink Shared Channel，上行物理共享信道)，用于传输上行控制信息的资源可以位于PUCCH(Physical Uplink Control Channel，上行物理控制信道)，用于传输PDU同时随路上行控制信息的资源可以位于PUSCH。
步骤602，所述至少两份资源在所述第一重叠区域对应的第一功率之和大于最大功率(该最大功率可以是终端设备在重叠区域的最大输出功率)，所述终端设备根据所述至少两份资源每一份的优先级确定所述至少两份资源每一份的功率因子；其中，基于所述功率因子将所述至少两份资源中每一份在所述重叠区域的第一功率进行调整后的功率之和小于或等于所述最大功率，并且所述至少两份资源中优先级高的资源的功率因子大，优先级低的资源的功率因子小。
在该实施例中，当终端利用至少两份资源向网络设备发送目标数据包时，终端可以根据预设规则，确定每个目标数据包对应的功率优先级或每个目标数据包所对应资源的功率优先级。
该预设规则有以下至少一种：
A，根据目标数据包所包含业务数据对应的优先级最高的逻辑信道，确定该目标数据包的功率优先级；
或者，根据目标数据包所包含业务数据对应的优先级最高的逻辑信道，确定该目标数据包对应资源的功率优先级。
所述逻辑信道的优先级，可以是网络设备配置的，用于构造协议数据单元的逻辑信道的优先级，也可以是网络设备配置的，专用于功率控制的逻辑信道的优先级。
B，如果任意一个目标数据包包含MAC CE(medium access control control element)，例如包括以下至少一个：BSR(buffer status report缓冲区状态报告)MAC CE、PHR(power headroom report功率余量报告)MAC CE、C-RNTI(cell radio network temporary identifier小区无线网络临时标识)MAC CE、Configured Grant confirmation(预配置授权确认)MAC CE，那么该目标数据包具有最高功率优先级，或，该目标数据包对应的资源具有最高功率优先级。
C，若协议数据单元包括随路上行控制信息，则确定协议数据单元的功率优先级或协议数据单元对应资源的功率优先级为高优先级。
上述预设规则可以联合使用，例如，终端可以根据规则A和C、A和B、B和C或A和B和C确定协议数据单元的功率优先级或协议数据单元对应资源的功率优先级。当在所述重叠区域，终端的发送功率受限时，终端根据至少一个协议数据单元中的每个协议数据单元对应的功率优先级或每个协议数据单元的物理资源对应的功率优先级，进行功率调整。在至少一个协议数据单元中的每个协议数据单元的资源中，协议数据单元对应的功率优先级或每个协议数据单元的物理资源对应的功率优先级的优先级越高，功率优先保证。
步骤603，所述终端设备使用所述至少两份资源每一份的功率因子分别对每一份资源进行功率调整；并按照每一份资源调整后的功率向无线接入设备发送数据。
在该实施例中可以针对所述至少一个目标数据包或所述至少一个目标数据包的资源进行功率缩放，优先级高的目标数据包的功率因子或目标数据包的资源的功率因子不小于优先级低的目标数据包的功率因子或目标数据包的资源的功率因子。
其中，终端使用缩放之后的功率，在所述至两份资源中向网络设备发送至少一个目标数据包。
终端根据针对所述至少两份资源，计算至少两个第一功率，每一份资源计算一个第一功率。在重叠区域，功率受限，优先保证功率优先级高的资源进行数据传输，也就是功率因子大，得到至少一个第二功率。终端使用所述至少一个第二功率，向网络设备在所述至少两份资源中发送目标数据包。
以图7a和图7b为例，两个逻辑信道(LCH1和LCH2)，LCH1的优先级为1，LCH2的优先级为2，优先级1大于2。终端有基站分配的两份资源，资源1，用于传输协议数据单元1(对应图7b中TB1)，资源2用于传输协议数据单元2(对应图7b中TB2)。其中，终端在生成协议数据单元时，协议数据单元1包含LCH1和LCH2的数据。在重叠区域，也就是虚线框所对应区域，功率受限，由于协议数据单元1包含的LCH1的数据，那么按照该实施例中所提供的功率调整原则，优先保证协议数据单元1的数据传输的功率。
图以图7a和图7c为例，两个逻辑信道(LCH1和LCH2)，LCH1的优先级为1，LCH2的优先级为2，优先级1大于2。终端有基站分配的两份资源，资源1，用于传输协议数据单元1(对应图7c中TB1)，资源2用于传输协议数据单元2和随路上行控制信息(对应图7C中TB2)。其中，终端在生成协议数据单元时，协议数据单元1包含LCH1和LCH2的数据，协议数据单元2仅包含LCH2的数据，但同时随路上行控制信息。在重叠区域，也就是虚线框所对应区域，功率受限，由于协议数据单元2随路上行控制信息，那么按照该实施例中所提供的功率调整原则，优先保证协议数据单元2的数据传输的功率。
以图7a和图7d为例，两个逻辑信道，LCH1和LCH2，LCH1的优先级为1，LCH2的优先级为2，优先级1大于2，且LCH1是特殊逻辑信道，例如LCH1承载URLLC(Ultra Reliability and Low Latency Communication，超高优先级超低时延)的数据。终端有基站分配的两份资源，资源1，用于传输协议数据单元1(对应图7d中TB1)，资源2用于传输协议数据单元2和随路上行控制信息(对应图7d中TB2)。其中，终端在生成协议数据单元时，协议数据单元1包含LCH1和LCH2的数据，协议数据单元2仅包含LCH2的数据，但同时随路上行控制信息。在重叠区域，也就是虚线框所对应区域，功率受限，虽然协议数据单元2随路上行控制信息，但协议数据单元1包含优先级高的特殊的逻辑信道，那么优先保证协议数据单元1的数据传输的功率。在具体的实施例中网络设备可以发送指示信息到终端设备，使得终端设备根据指示信息确定哪些是特殊逻辑信道，允许这些逻辑信道的优先级高于上行控制信息。
