Description

功率分配方法、功率调整方法、终端和接入网设备 技术领域
本申请涉及通信技术领域，特别涉及一种功率分配方法、功率调整方法、终端和接入网设备。
背景技术
高级长期演进(Long Term Evolution–Advanced，简称“LTE-A”)系统是第三代合作伙伴计划(3rd Generation Partnership Project，简称“3GPP”)长期演进(Long Term Evolut ion，简称“LTE”)系统的进一步演进和增强系统。在LTE-A系统中，为了满足国际电信联盟对于第四代通信技术的峰值数据速率要求引入了载波聚合(Carrier Aggregation，简称“CA”)技术，也称频谱聚合(Spectrum Aggregation)技术或者带宽扩展(Bandwidth Extension)技术。载波聚合中，两个或更多的成员载波(Component Carrier)的频谱被聚合在一起以得到更宽的传输带宽。
在载波聚合场景下，不同载波上的上行子帧会存在交叠的现象，这种现象的形成主要包括以下两种情况(下述描述均以两个载波为例，实际可以包括多个载波)：
第一种情况，第一载波上的上行子帧和第二载波上的上行子帧的长度相差较大，使得第二载波上的一个上行子帧对应第一载波上的多个上行子帧。具体地，在5G高频场景下，不同载频下的最小传输时间粒度(即传输数据的最小时间单元)不同，例如，高频28GHz的一个子帧长度为0.3ms，而低频2GHz的一个子帧长度可设置为1ms，从而使得一个低频子帧对应了多个高频子帧。
第二种情况，第一载波上的上行子帧和第二载波上的上行子帧的长度相近或相同，但由于第一载波上的上行子帧和第二载波上的上行子帧起始时间不同，从而使得第一载波上的上行子帧和第二载波上的上行子帧之间位置出现偏差，导致第二载波上的一个上行子帧和第一载波上的两个上行子帧之间存在交叠。具体地，两个载波属于两个定时提前组(Timing Advance Group，简称“TAG”)，导致两个载波上的上行发送信道的定时提前量不同，进而导致两个载波上的上行子帧的起始时间不同并会存在交叠。
而终端在通过两个载波的上行子帧传输上行数据前，要为对应的上行子帧的信道分配功率，通常的功率分配方法是根据下行控制信息(Downlink Control Information，简称“DCI”)确定每个上行子帧需要的信道发射功率(也即上行子帧中传输的信道的发射功率)，然后根据两个载波在交叠的上行子帧上的信道的优先级，确定两个载波在交叠的上行子帧上的信道的发射功率。具体地，在进行功率分配之前，终端可以获得分别与两个载波对应的两个DCI。对于第二载波而言，根据其对应的DCI即可确定需要进行功率分配的一个上行子帧上的待传输信道的信息，包括功率分配信息等，而对于第一载波而言，在获得第二载波对应的DCI时，可能只能获得与第二载波的这个上行子帧发生重叠的第一载波的前若干个(或一个)上行子帧上的信道的信息，而不包括第一载波的后若干个(或一个)上行子 帧上的信道的信息，造成根据所述两个载波交叠的上行子帧上的信道的优先级进行功率分配时，无法考虑第一载波在所述两个载波交叠的后若干个(或一个)上行子帧上的信道需要的发射功率。
由于上述原因，使得按照上述方案分配的功率可能不满足第一载波的后若干个(或一个)上行子帧上的信道的发射功率需求。
另外，在第二载波的一个上行子帧(长子帧)与第一载波的多个上行子帧(短子帧)存在交叠的场景中，可能由于其中一个短子帧所要分配的功率较多，导致整个长子帧的功率分配不能被有效满足的情况。

本申请通过在一个载波的上行子帧与另一个载波的多个上行子帧间存在交叠时，通过为交叠区域的后半部分预留最小保证功率，从而使得在进行两个载波间的上行功率分配时可以考虑到交叠区域的后半部分的功率需求，进而使得交叠区域的后半部分的上行子帧上的数据传输性能得到保证，实现了上行数据传输的功率效率和数据传输性能的最大化。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施方式作进一步地详细描述。
图1和图2示出了本发明实施例提供的通信系统的结构示意图。该通信系统可以是LTE系统或5G系统。该通信系统包括：至少一个终端120和至少一个基站140。
图1和图2示出的通信系统分别对应两种不同的应用场景。为便于对本发明实施例提供的技术方案的理解，首先结合图1和图2介绍一下本申请的应用场景。
第一种应用场景(参见图1)：接入网设备(如基站)间的载波聚合场景
终端120同时与两个接入网设备140进行数据传输，实现载波聚合。如图1所示，终端120通过载波A向一个接入网设备140传输上行数据，终端120通过载波B向另一个接入网设备140传输上行数据。这种场景下，两个接入网设备140之间包括可以实时进行数据交互(理想回传)和不可以实时进行数据交互(非理想回传)两种情况。上行数据和所述下行数据分别以载波A(或载波B)的上行子帧和下行子帧作为载体进行传输。
如果载波A和载波B属于2个不同的TAG，由于不同的TAG定时提前量不同，终端120向两个接入网设备140发送上行数据的子帧的起始时间不同，因此，无论两个子帧的长度相差较大或较小，两个接入网设备对应的上行子帧间均存在不对齐和/或重叠的时间。或存在一个接入网设备对应的一个上行子帧和另一个接入网设备对应的至少两个上行子帧间存在交叠的情况。
如果载波A和载波B属于2相同的TAG，由于相同的TAG定时提前量相同，终端120向两个接入网设备140发送上行数据的上行子帧的起始时间相同，因此，只有两个子帧的长度相差较大时，两个上行子帧间才存在不对齐和/或重叠的时间。或存在一个接入网设备对应的一个上行子帧和另一个接入网设备对应的至少两个上行子帧间存在交叠的情况。
第二种应用场景(参见图2)：单接入网设备载波聚合
终端120通过两个以上载波进行数据传输，实现载波聚合。如图2所示，终端120同时通过载波A和B向接入网设备140传输上行数据。
如果载波A和载波B属于2个不同的TAG，由于不同的TAG定时提前量不同，终端120 向接入网设备140发送上行数据的上行子帧的起始时间不同，因此，无论两个子帧的长度相差较大或较小，两个接入网设备对应的上行子帧间均存在不对齐和/或重叠的时间。或存在一个接入网设备对应的一个上行子帧和另一个接入网设备对应的至少两个上行子帧间存在交叠的情况。
如果载波A和载波B属于两个相同的TAG，由于相同的TAG定时提前量相同，终端120向接入网设备140发送上行数据的上行子帧的起始时间相同，因此，只有两个子帧的长度相差较大时，两个接入网设备对应的上行子帧间均存在不对齐和/或重叠的时间。或存在一个接入网设备对应的一个上行子帧和另一个接入网设备对应的至少两个上行子帧间存在交叠的情况。
下面结合图3对两个子帧的长度相差较大的情况进行说明。如图3所示，终端通过低频载波(Low Frequency Carrier)和高频载波(High Frequency Carrier)与接入网设备实现载波聚合传输，低频载波上的子帧的长度大于高频载波上的子帧的长度，低频载波上的子帧为长子帧，高频载波上的子帧为短子帧，低频载波上的一个长子帧与高频载波上的多个短子帧发生交叠。
终端为长子帧i和与其存在交叠的多个短子帧分配发射功率时，需要知道这些短子帧所需要的信道发射功率，而每个短子帧所需要的信道发射功率通常通过DCI中携带的信息(例如调度决策和功率控制命令)确定。如图3所示，终端在t时刻为长子帧i和与其存在交叠的短子帧(i 1到iN)分配发射功率，此时终端接收到的DCI包括DCI 1和DCI2，其中DCI 1携带有用于确定长子帧i的信道发射功率的信息，而DCI2仅携带有用于确定与长子帧i存在交叠的N个短子帧中前M个短子帧的信道发射功率的信息，而用于确定后N-M个短子帧的信道发射功率的信息携带在DCI 3中，因此按照传统方式在t时刻进行功率分配就无法考虑到后N-M个短子帧的功率需求。
另外，在一些场景中如果仅按照现有的方式进行功率分配，也会对长子帧的发射功率造成影响。
例如，在动态时分双工(Time Division Duplexing，简称“TDD”)中，与长子帧存在交叠的多个短子帧中可能前2个短子帧是上行子帧，所需信道发射功率较大，而后若干个短子帧为下行子帧，所需信道发射功率较小；若短子帧的信道的优先级高于长子帧，按照现有的功率分配方式，由于在功率受限时优先将功率分配给了交叠区域的短子帧，从而导致可分配给长子帧上的上行数据可能达不到所需的信道发射功率，而短子帧上的上行数据传输所分配到的信道发射功率，在多数时间内均超过其实际所需的信道发射功率，最终造成短子帧上的上行数据传输的发射功率的浪费和长子帧上的上行数据传输的功率分配的不足。
本申请的所有实施例既适用于第一种应用场景也适用于第二种应用场景。
下面结合具体的硬件结构对实现本发明实施例提供的终端和接入网设备进行说明。

本领域技术人员可以理解，图5中所示出的接入网设备140的结构并不构成对接入网设备的限定，可以包括比图示更多或更少的部件或组合某些部件，或者不同的部件布置。
参见图6，其示出了本发明实施例提供的一种功率分配方法，该方法采用图1或图2所示的系统实现，该方法包括：
S100：终端确定第一初始发射功率和第二初始发射功率，第一初始发射功率包括第一载波承载的在M个第一子帧中的每个第一子帧中传输的信道的初始发射功率，第二初始发射功率为第二载波承载的在第二子帧中传输的信道的初始发射功率。
在功率分配前，终端会接收到DCI(例如图3中的DCI 1和DCI2)，其中DCI 1携带有用于确定长子帧i的信道发射功率的信息，而DCI2仅携带有用于确定与长子帧i存在交叠的N个短子帧中前M个短子帧的信道发射功率的信息。终端根据上述DCI确定第一初始发射功率和第二初始发射功率。
S101：接入网设备确定第一载波承载的信道的最小保证功率信息。
其中，第一载波承载的信道的最小保证功率信息可以为最小保证功率与最大发射功率的比值的索引。
其中，第一载波承载的信道的最小保证功率大于或等于0，且最小保证功率与最大发射功率PCMAX的比值可以是百分比(in％)。
例如，第一载波承载的信道的最小保证功率与最大发射功率的比值可以为下面列举的候选取值中的任意一个：0％，5％，10％，15％，20％，30％，37％，44％，50％，56％，63％，70％，80％，90％，95％，100％。根据最小保证功率信息中的索引确定第一载波承载的信道的最小保证功率，例如索引为6，则对应的最小保证功率与最大发射功率的比值为30％，则根据最大发射功率即可计算出最小保证功率。
在确定第一载波承载的信道的最小保证功率信息时，可选地，接入网设备可以根据在交叠的若干个上行短子帧上的待传输数据的类型和优先级，确定第一载波承载的信道的最小保证功率信息。
其中，接入网设备可以根据交叠的若干个上行短子帧上的待传输数据类型确定第一载波承载的信道的最小保证功率信息。具体地，当交叠的若干个上行短子帧上的待传输数据中的信道优先级较高(例如优先级最高的若干种数据类型)时，第一载波承载的信道的最小保证功率与最大发射功率的比值可以大于或等于设定值(如50％)。例如，当在交叠的若干个上行短子帧上的待传输数据类型中有物理随机接入信道时，考虑到物理随机接入信道的优先级较高，因此所述第一载波承载的信道的最小保证功率信息可以为大于等于50％的上述候选取值中的任意一个。
在一种实现方式中，步骤S101中所指的第一载波承载的信道的最小保证功率信息，仅用于终端在有效期内为第一载波在交叠的若干个上行子帧上的上行数据分配功率时使用，该有效期可以是次数(例如一次或几次)，也可以是时间(例如一段时间内)。
在另一种实现方式中，步骤S101中所指的第一载波承载的信道的最小保证功率信息可以用于终端在任意一次为第一载波在交叠的若干个上行子帧上的功率分配使用。
S102：接入网设备向终端发送第一载波承载的信道的最小保证功率信息。
实现时，S102可以包括：接入网设备向终端发送高层信令或物理层信令，高层信令或物理层信令包括第一载波承载的信道的最小保证功率信息。
其中，高层信令可以为无线资源控制(Radio Resource Control，简称“RRC”)信令，物理层信令可以为DCI信令。
实现时，S102可以包括：接入网设备通过第一载波或第二载波发送第一载波承载的信道的最小保证功率信息。
也就是说，高层信令或物理层信令可以为通过第二载波发送的高层信令或物理层信令，或者高层信令或物理层信令也可以为通过第一载波发送的高层信令或物理层信令。
进一步地，物理层信令为主载波(如上述的第二载波)发送的物理层信令，或者物理 层信令为辅载波(如上述的第一载波)发送的物理层信令。例如，DCI信令为主载波发送的DCI信令，或者DCI信令为辅载波发送的DCI信令。DCI信令可以为一种专用于传输最小保证功率信息的DCI信令(不同于用于进行下行链路授权(DL grant)的DCI信令)。
可选地，接入网设备还通过指示信令向终端发送第一载波承载的在N个第一子帧中的信道的功率分配信息。所述指示信令为承载了第一载波承载的在N个第一子帧中每个第一子帧上的信道的功率分配信息的高层信令或物理层信令。其中，当所述指示信令为物理层信令时，通过第一载波发送的所述第一信令的传输子帧与通过第二载波发送的第二信令的传输子帧存在交叠，第二信令携带第二载波在第二子帧中承载的信道的功率分配信息。
例如，如图3所示，DCI2承载了第一载波承载的在N个第一子帧中的信道的功率分配信息。或者，在DCI2和/或DCI2之前接入网设备向终端发送了2个DCI，两个DCI分别用于指示第一载波承载的在M个第一子帧中的信道的功率分配信息和第一载波承载的在N-M个第一子帧中的信道的功率分配信息。
S103：终端接收接入网设备传输的第一载波承载的信道的最小保证功率信息。
实现时，S103可以包括：终端接收接入网设备通过第一载波或第二载波发送的第一信令，第一信令为携带第一载波承载的信道的最小保证功率信息的高层信令或物理层信令。
其中，通过第一载波发送的第一信令的传输子帧与通过第二载波发送的第二信令的传输子帧存在交叠，第二信令携带第二载波在第二子帧中承载的信道的功率分配信息。
以图3为例，第二信令可以为DCI 1，第一信令可以为DCI2，DCI 1和DCI2的传输子帧间存在交叠。另外，DCI2中携带第一载波承载的信道的最小保证功率信息可以在后述的功率分配中使用。
可选地，终端接收接入网设备通过指示信令发送的第一载波承载的在N个第一子帧中的信道的功率分配信息。
S104：当第一初始发射功率中的任一初始发射功率与第二初始发射功率之和大于终端的最大发射功率时，终端根据第一载波承载的在M个第一子帧中传输的信道与第二载波承载的在第二子帧中传输的信道的优先级排序，以及第一载波承载的信道的最小保证功率信息，得到第一载波承载的在N个第一子帧中传输的信道的可用发射功率和第二载波承载的在第二子帧中传输的信道的可用发射功率。
其中，第二载波上的第二子帧与第一载波上的N个第一子帧存在交叠，M个第一子帧为N个第一子帧中的前M个第一子帧，N大于M，且M、N为正整数。
其中，第一子帧和第二子帧均可以为上行子帧。M个第一子帧的长度相同，但传输的信道可以不同。
进一步地，第二载波上的第二子帧与第一载波上的N个第一子帧的交叠时间大于或等于预设阈值，其中交叠时间是指存在交叠部分的时间长度，阈值可以为一个时间也可以是在N个第一子帧时间长度中所占的比例，例如N个第一子帧时间长度的百分之五十。
例如，参见图6A，低频载波(第二载波)上的一个上行子帧(第二子帧)与高频载波(第一载波)上的3个上行子帧(第一子帧)交叠(例如，低频载波可以是2GHz，高频载波为28GHz；或者，高低频载波可以为其他数值，只要其对应的上行子帧长度之间关系为1比3即可)，在进行功率分配时，终端可以根据高频载波上的前2个上行子帧的信道和与其存在交叠的低频载波上的一个上行子帧的信道的优先级以及高频载波上的上行数据传输的 最小保证功率信息，得到高频载波的3个上行子帧上的上行数据传输的发射功率和低频载波上的一个上行子帧上的上行数据传输的发射功率。
实现时，S104可以包括：
S1041：终端根据第一载波承载的信道的最小保证功率信息得到最小保证功率。
以步骤S101中的最小保证功率信息为最小保证功率的索引为例，终端中存储有最小保证功率与最大发射功率的比值的候选取值，在获取到最小保证功率的索引后，根据该索引从这些候选取值中确定出最小保证功率与最大发射功率的比值，然后根据该比值及最大发射功率即可计算出最小保证功率。
S1042：终端根据第一载波承载的在M个第一子帧中传输的信道与第二载波承载的在第二子帧中传输的信道的优先级排序，得到第一载波承载的在N个第一子帧中传输的信道的第一可用发射功率以及第二载波承载的在第二子帧上中传输的信道的第二可用发射功率。
在步骤S1042中，终端为了确定出第一载波承载的在M个第一子帧中传输的信道与第二载波承载的在第二子帧中传输的信道的优先级排序，需要先获取优先级排序规则，优先级排序规则用于确定上行子帧的信道之间的优先级排序。
在一种实现方式中，优先级排序规则可以是事先预定义的，预先存储在终端中，终端在优先级确定时，直接获取即可。
在另一种实现方式中，该优先级排序规则由接入网设备发送给终端。该过程具体可以包括：
第一步：接入网设备将优先级排序规则发送给终端。
实现时，接入网设备可以通过高层信令或物理层信令向终端发送优先级排序规则。
其中，高层信令可以为RRC信令，物理层信令可以为DCI信令。
实现时，接入网设备可以通过第一载波或第二载波将优先级排序规则发送给终端。
也就是说，接入网设备通过第一载波或第二载波向基站发送高层信令或物理层信令，高层信令或物理层信令包括优先级排序规则，优先级排序规则用于确定第一载波承载的在M个第一子帧中传输的信道与第二载波承载的在第二子帧中传输的信道的优先级排序。不同场景有不同的优先级排序规则，接入网设备可根据不同的场景为不同的用户配置不同的优先级排序规则。
进一步地，物理层信令为主载波(如上述的第二载波)发送的物理层信令，或者物理层信令为辅载波(如上述的第一载波)发送的物理层信令。例如，DCI信令为主载波发送的DCI信令，或者DCI信令为辅载波发送的DCI信令。
在本实施例中，信道的优先级排序包括种：
信道的类型的优先级排序、信道携带的上行控制信息(Uplink Control Information，简称“UCI”)的优先级排序、信道对应载波的优先级排序中的至少一种。
具体地，信道类型的优先级排序包括以下至少一种：
当存在有物理随机接入信道(Physical Random Access Channel，简称“PRACH”)时，PRACH的优先级最高；
当物理上行控制信道(Physical Uplink Control Channel，简称“PUCCH”)和物理上行共享信道(Physical Uplink Shared Channel，简称“PUSCH”)同时存在时，PUCCH的优先级高于PUSCH的优先级，或者，PUCCH的优先级高于未携带UCI的PUSCH的优先级且和携带 UCI的PUSCH的优先级相同；
当携带上行控制信息UCI的PUSCH和未携带UCI的PUSCH同时存在时，携带UCI的优先级高于未携带UCI的PUSCH；
在PRACH、PUCCH、PUSCH和探测参考信号(Sounding Reference Signal，简称“SRS”)同时存在时，SRS的优先级最低。
具体地，信道携带的UCI的优先级排序包括以下至少一种：
当存在有信道状态信息和调度请求时，信道状态信息的优先级低于调度请求的优先级；
当存在有混合自动重传请求信息和调度请求时，混合自动重传请求信息的优先级高于或等于调度请求的优先级。
具体地，信道对应载波的优先级排序包括：
基于载波的索引序号确定的优先级排序、高层配置的载波优先级排序、基于载波的双工方式确定的优先级排序、基于载波的无线资源连接RRC连接情况确定的优先级排序和基于载波对应的传输点确定的优先级排序中的至少一种。
其中，基于载波的RRC连接情况确定的优先级排序包括以下至少一种：
支持RRC连接的载波的优先级高于不支持RRC连接的载波的优先级；
承载RRC信息的载波的优先级高于不承载RRC信息的载波的优先级。
上述优先级排序还可以根据实际场景对应设置，例如，在一种场景下，采用主载波传输RACH，辅载波传输确认指令(Acknowledgment，简称“ACK”)(通过PUSCH承载)，此时信道类型的优先级排序中PRACH>PUSCH。
进一步地，信道类型的优先级排序可以为：PRACH>PUCCH>PUSCH with UCI>PUSCH without UCI>SRS。即多个载波间的上行信道中随机接入信道的优先级最高，其次为上行控制信道，然后为传输UCI的上行共享信道和不传UCI的上行共享信道，最后为探测参考信号。
在另一种场景下，该场景涉及多波束扫描的场景，具体地：终端将多份随机接入信道(Random Access Channel，简称“RACH”)通过多个波束进行时分发送，以10份RACH为例，在两个载波的上行子帧存在交叠的场景中，如果前6份RACH的发送子帧和第i-1个长子帧交叠，后6份RACH的发送子帧和第i个长子帧交叠，则在为第i个长子帧及交叠的短子帧分配信道发射功率时，信道的类型的优先级排序中RACH的优先级可以小于PUCCH，即PUCCH>PRACH。
在另一种场景下，信道对应载波或小区组的优先级排序可以为：主载波或小区组的任意上行信道的优先级大于或等于辅载波或小区组的任意上行信道的优先级。
实现时，该步骤可以包括：
接入网设备根据即将被调度的数据信道的类型确定对应的优先级排序规则；接入网设备将对应的优先级排序规则发送给终端。
第二步：终端接收接入网设备发送的优先级排序规则。
具体地，终端接收接入网设备通过第一载波或第二载波发送的高层信令或物理层信令，高层信令或物理层信令包括优先级排序规则，优先级排序规则用于确定第一载波承载的在M个第一子帧中传输的信道与第二载波承载的在第二子帧中传输的信道的优先级排序。
第三步：终端根据优先级排序规则确定第一载波承载的在M个第一子帧中传输的信道与第二载波承载的在第二子帧中传输的信道的优先级排序。
在一种实现方式中，终端根据接收到的优先级排序规则先从第一载波的M个第一子帧中选择出一个第一子帧，然后采用这个第一子帧中传输的信道和第二子帧中传输的信道进行优先级比较。
从第一载波的M个第一子帧中选择一个第一子帧具体包括：选择这M个第一子帧中信道优先级最高的第一子帧。也可以选择这M个第一子帧中信道优先级最低的第一子帧，或者选择这M个第一子帧中信道优先级处于设定排位(例如优先级处于第二)的第一子帧。
在比较两个上行子帧的信道优先级时，根据不同的优先级排序规则有不同的比较方式。
当优先级排序规则只包括前述优先级排序中的一个时，例如只包括信道的类型的优先级排序，此时，如果两个上行子帧的信道的类型相同，则优先级相同。
当优先级排序规则只包括前述优先级排序中的两个以上时，例如包括信道的类型的优先级排序和信道携带的UCI的优先级排序，此时，如果两个上行子帧的信道的类型相同，如均为携带了上行控制信息的信道类型时，则比较信道携带的UCI的优先级。
在获取到优先级排序规则并确定了优先级排序后，即可根据第一载波承载的在M个第一子帧中传输的信道与第二载波承载的在第二子帧中传输的信道的优先级排序，得到第一载波承载的在N个第一子帧中传输的信道的第一可用发射功率以及第二载波承载的在第二子帧上传输的信道的第二可用发射功率，包括：
基于优先级排序，对第一初始发射功率与第二初始发射功率进行缩减，分别得到第一载波承载的在N个第一子帧中传输的信道的第一可用发射功率与第二载波承载的在第二子帧中传输的信道的第二可用发射功率，第一载波承载的在N个第一子帧中传输的信道的第一可用发射功率与第二载波承载的在第二子帧中传输的信道的第二可用发射功率之和小于或等于最大发射功率。
具体地，对优先级低的信道的初始发射功率进行缩减，直到第一载波承载的在N个第一子帧中传输的信道的第一可用发射功率与第二载波承载的在第二子帧中传输的信道的第二可用发射功率之和小于或等于最大发射功率。
或者，对不同优先级的信道的按照不同的缩减比例对各自的初始发射功率进行缩减(优先级低的缩减比例大于优先级高的缩减比例)，直到第一载波承载的在N个第一子帧中传输的信道的第一可用发射功率与第二载波承载的在第二子帧中传输的信道的第二可用发射功率之和小于或等于最大发射功率。
S1043：终端根据第一可用发射功率和第二可用发射功率中的至少一个以及最小保证功率，确定第一载波承载的在N个第一子帧中传输的信道的可用发射功率和第二载波承载的在第二子帧中传输的信道的可用发射功率中的至少一个。在步骤S1043中，终端可以根据如下方式确定第一载波承载的在N个第一子帧中传输的信道的可用发射功率：Maximum{P_priority,P_guranteed}，P_priority为第一载波承载的在N个第一子帧中传输的信道的第一可用发射功率，P_guranteed为最小保证功率。此时，第二载波承载的在第二子帧中传输的信道的可用发射功率可以为第二可用发射功率。
除了上述取最大值的方案外，还可以采用取最小值或者平均值的方式确定第一载波承载的在N个第一子帧中传输的信道的可用发射功率，这里不做限制。
需要说明的是，最终得到的第一载波承载的在N个第一子帧中传输的信道的可用发射功率和第二载波承载的在第二子帧中传输的信道的可用发射功率之和小于或等于最大发射 功率。
进一步地，该方法还可以包括：终端按照第一载波承载的在N个第一子帧中传输的信道的可用发射功率发射第一载波承载的在N个第一子帧中传输的信道，按照第二载波承载的在第二子帧中传输的信道的可用发射功率发射第二载波承载的在第二子帧中传输的信道。
或者，步骤S1043中只确定出第一载波承载的在N个第一子帧中传输的信道的可用发射功率时，该方法还可以包括：终端按照第一载波承载的在N个第一子帧中传输的信道的可用发射功率发射第一载波承载的在N个第一子帧中传输的信道，按照第二载波承载的在第二子帧中传输的信道的第二可用发射功率发射第二载波承载的在第二子帧中传输的信道。
或者，步骤S1043中只确定出第二载波承载的在第二子帧中传输的信道的可用发射功率时，该方法还可以包括：终端按照第一载波承载的在N个第一子帧中传输的信道的第一可用发射功率发射第一载波承载的在N个第一子帧中传输的信道，按照第二载波承载的在第二子帧中传输的信道的可用发射功率发射第二载波承载的在第二子帧中传输的信道。
本申请通过在一个载波或小区组的上行子帧与另一个载波或小区组的多个上行子帧间存在交叠时，通过为交叠区域的后半部分预留最小保证功率，从而使得在进行两个载波间的上行功率分配时可以考虑到后半部分的功率需求，进而使得交叠区域的后半部分的上行子帧上的数据传输性能得到保证，实现了上行数据传输的功率效率和数据传输性能的最大化。
参见图7，其示出了本发明实施例提供的一种功率调整方法，该方法采用图1或图2所示的系统实现，该方法包括：
S201：接入网设备确定功率调整因子。
其中，功率调整因子用于确定子帧第一部分上的信道的可用发射功率和子帧第二部分上的信道的可用发射功率的偏移值，具体用于在终端进行上行子帧上的数据发送时，对该上行子帧上的数据的发射功率进行调整。具体地，终端采用第一功率发送该上行子帧的第一部分上的上行数据，然后采用根据该偏移量和第一功率进行计算得到第二功率，采用第二功率发送该上行子帧的第二部分上的上行数据。
具体地，上述偏移值可以为比值或差值；当功率调整因子为差值时，通过控制偏移值的正负来实现增大或者减小第一功率，从而得到第二功率。当功率调整因子为比值时，通过控制功率比值大于或小于1来实现增大或者减小第一功率，从而得到第二功率。
实现时，功率调整因子是小区特定的参数，即功率调整因子的设置以小区为单位，即功率调整因子是个小区特定的参数。实现时，步骤S201可以包括：接入网设备确定终端所在的小区；接入网设备根据终端所在的小区确定对应的功率调整因子。
S202：接入网设备向终端发送功率调整因子。
实现时，S202可以包括：接入网设备通过高层信令或物理层信令向终端发送功率调整因子。
其中，高层信令可以为RRC信令，物理层信令可以为DCI信令。
进一步地，物理层信令为主载波(如上述的第二载波)上传输的物理层信令，或者物 理层信令为辅载波(如上述的第一载波)上传输的物理层信令。例如，DCI信令为主载波上传输的DCI信令，或者DCI信令为辅载波上传输的DCI信令。
S203：终端接收接入网设备发送的功率调整因子。
实现时，S203可以包括：终端接收接入网设备通过高层信令或物理层信令发送的功率调整因子。
S204：终端根据功率调整因子和终端在上行子帧的第一部分上的信道的发射功率得到终端在上行子帧的第二部分上的信道的发射功率，上行子帧包括第一部分和第二部分，且第二部分位于第一部分之后。
终端根据功率调整因子确定两个部分的发送功率后，将一个上行子帧通过确定出的两种发射功率进行发送。一个上行子帧的两个部分可以按照符号或时隙进行划分，这里不做限定。
本申请通过在数据传输过程中，采用功率调整因子对上行子帧的两个部分上的信道的发射功率进行调整，使得上行子帧的两个部分上的信道的发射功率可以实时调整，从而可最大化上行子帧的两个部分上的信道的功率分配和功率效率。
