本公开实施例提供了一种上行多波束功率控制方法，应用于终端，如图2所示，该方法具体包括以下步骤：
步骤21：获取目标信道或目标信号对应的至少两个发送波束的资源标识信息。
终端接收网络设备发送的资源标识信息，该资源标识信息用于指示：目标信道或目标信号对应至少两个(多个)发送波束。具体地，目标信道包括：物理上行共享信道NR-PUSCH、物理上行控制信道NR-PUCCH和物理随机接入信道NR-PRACH中的至少一种信道，目标信号包括：信道探测参考信号。
具体地，由于终端支持多波束传输，网络设备可为同一目标信道或目标信号配置多个不同的发送波束(上行波束)，例如，为NR-PUCCH配置波束0至3，为NR-PUSCH配置波束4-7，为NR-PRACH配置波束8-9。
由于终端支持多波束传输，多个波束同时发送时的总发射功率可能会超过终端的最大发射功率，从而导致传输失败，为了避免这种问题发生，本公 开实施例可通过以下步骤将多个波束的总发射功率限制在终端的最大发射功率范围内。本申请的实施例中以NR系统中的通信信号，例如NR-PRACH以及NR-PUSCH为例进行说明，所属领域技术人员可以了解，NR系统，以及NR系统中的信号仅为示例说明，并不构成对本发明保护范围的限定。
步骤22：若资源标识信息对应的至少两个发送波束的总发射功率超过终端的最大发射功率，则通过发送波束中的部分波束向基站发送上行信号。
步骤22指的是终端主动选择NR-PUSCH或NR-PUCCH或NR-PRACH或NR-SRS Multi-beam对应的多个发送波束中部分波束进行上行信号的发送，以保证发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
步骤23：若资源标识信息对应的至少两个发送波束的总发射功率超过终端的最大发射功率，则将发送波束的总发射功率调整至最大发射功率以下后再向基站发送上行信号。
步骤23指的是终端主动调整NR-PUSCH或NR-PUCCH或NR-PRACH或NR-SRS Multi-beam对应的多个发送波束中部分或全部波束的发射功率，以保证发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
步骤24：若资源标识信息对应的至少两个发送波束的总发射功率超过终端的最大发射功率，则对发送波束分组，并通过分组后的发送波束分别向基站发送上行信号。
步骤24指的是终端将NR-PUSCH或NR-PUCCH或NR-PRACH或NR-SRS Multi-beam对应的多个发生波束进行分组，并通过每分组向网络设备发送上行信号，以保证每组发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
以上简单介绍了本公开实施例上行多波束功率控制方法，下面将结合具体应用场景对其做进一步介绍说明。由于相同或不同的目标信号可能对应不同的发送波束，不同的波束对应场景，对应不同的功率控制方式。其中，
方式一、单个目标信道或目标信号可对应至少两个发送波束，即相同目 标信道或目标信号对应多个不同的发送波束，若至少两个发送波束对应相同目标信道或目标信号，步骤22具体为：根据发送波束的传输质量从优至差的排列次序，将除所述排列次序中后M个波束之外的剩余波束确定为第一目标发送波束；通过第一目标发送波束向基站发送上行信号。其中，M为正整数，第一目标发送波束的总发射功率低于或等于最大发射功率。其中，M的值小于目标信道或目标信号对应的发送波束的最大波束数。上述丢弃后M个波束的过程可以是一次丢弃一个发送波束进行的，具体地，当检测到目标信道或目标信号对应的多个发送波束的总发射功率超过最大发射功率时，先将波束传输质量最差的一个波束丢弃，并检测剩余波束的总发射功率是否低于最大发射功率，若低于则停止丢弃其他发送波束，若仍高于总发射功率，则继续丢弃剩余波束中波束传输质量最差的波束，直至剩余波束的总发射功率低于最大发射功率为止。
具体地，根据发送波束的传输质量从优至差的排列次序，将除所述排列次序中后M个波束之外的剩余波束确定为第一目标发送波束包括：获取各个发送波束的传输质量，并按照传输质量从优至差排序，得到一排列次序；将排列次序中后M个波束丢弃，并检测剩余波束的总发射功率是否低于或等于最大发射功率；若低于或等于，则将剩余波束确定为第一目标发送波束。
进一步地，发送波束的传输质量可通过检测波束路损或波束接收功率来确定。具体地，上述确定第一目标发送波束的步骤具体为：获取各个发送波束的波束路损，按照波束路损由低到高对各个发送波束进行排序，得到一排列次序，将该排列次序中后M个波束丢弃，并检测剩余波束的总发射功率是否低于或等于最大发射功率，若低于或等于，则将剩余波束确定为第一目标发送波束。
或者，传输质量还可通过检测波束接收功率来确定，具体地，上述确定第一目标发送波束的步骤具体为：获取各个发送波束对应的接收波束的波束接收功率，按照波束接收功率由高到低对相应的各个发送波束进行排序，得到一排列次序，将该排列次序中后M个波束丢弃，并检测剩余波束的总发射功率是否低于或等于最大发射功率，若低于或等于，则将剩余波束确定为第一目标发送波束。
假设网络侧配置终端采用多波束传输方式进行NR-PRACH的发送，终端最大支持NR-PRACH的2波束发送。其中，第1个波束参考信号接收功率大于第2个波束参考信号接收功率，2个发送波束的总发射功率超过终端的最大发射功率且每一发送波束的发射功率均低于终端的最大发射功率，这时终端将会放弃NR-PRACH的第2个波束发送。这样，通过丢弃传输质量差的发送波束以保证总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
方式二、单个目标信道或目标信号可对应至少两个发送波束，即相同目标信道或目标信号对应多个不同的发送波束，若至少两个发送波束对应相同目标信道或目标信号，步骤22还可通过以下步骤实现：将发送波束中随机选择的N个波束确定为第二目标发送波束；通过第二目标发送波束向基站发送上行信号。其中，N为正整数，第二目标发送波束的总发射功率低于或等于最大发射功率。
该方式为终端随机选择NR-PUSCH或NR-PUCCH或NR-PRACH或NR-SRS的发送波束，以保证发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
方式三、单个目标信道或目标信号可对应至少两个发送波束，即相同目标信道或目标信号对应多个不同的发送波束，若至少两个发送波束对应相同目标信道或目标信号，步骤23具体包括：分别调整每个发送波束的发射功率直至发送波束的总发射功率低于或等于最大发射功率；通过调整发射功率后的发送波束，向基站发送上行信号。
该方式为终端主动调整NR-PUSCH或NR-PUCCH或NR-PRACH或NR-SRS对应的多个发送波束中部分或全部波束的发射功率，以保证发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
方式四、单个目标信道或目标信号可对应至少两个发送波束，即相同目标信道或目标信号对应多个不同的发送波束，若至少两个发送波束对应相同目标信道或目标信号，步骤24具体包括：将至少两个发送波束分为多组，通 过时分复用的多组发送波束，分别向基站发送上行信号。其中，每组发送波束的总发射功率低于或等于最大发射功率。
该方式为终端将NR-PUSCH或NR-PUCCH或NR-PRACH或NR-SRS对应的多个波束按照时分方式轮流发送，以保证每组发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
方式五、多个目标信道或目标信号可对应至少两个发送波束，即不同目标信道或目标信号对应多个不同的发送波束，若至少两个发送波束对应不同目标信道或目标信号，步骤22具体包括：根据不同目标信道或目标信号的优先级从高到低的序列，获取所述序列中后P个第一目标信道或第一目标信号；将第一目标信道或第一目标信号中的部分波束丢弃，并将除丢弃波束之外的剩余波束确定为第三目标发送波束；通过第三目标发送波束，向基站发送上行信号。其中，目标信道或目标信号的优先级是预配置的，或由网络设备配置并通知终端的，P为正整数，第三目标发送波束的总发射功率低于或等于最大发射功率。
上述丢弃后P个目标信道或目标信号的部分波束的过程可以是一次丢弃一个目标信道或目标信号的部分波束进行的，具体地，当检测到目标信道或目标信号对应的多个发送波束的总发射功率超过最大发射功率时，先将优先级最低的一个目标信道或目标信号的部分波束丢弃，并检测所有目标信道和目标信号剩余波束的总发射功率是否低于最大发射功率，若低于则停止丢弃其他发送波束，若仍高于总发射功率，则继续丢弃剩余目标信道和目标信号中优先级最低的目标信道或目标信号的部分波束，直至所有目标信道和目标信号剩余波束的总发射功率低于最大发射功率为止。
假设网络侧配置终端采用多波束传输方式进行NR-PRACH和NR-PUSCH的发送，终端最大支持3波束发送，第1个波束用于NR-PRACH发送，第2个和第3个波束用于NR-PUSCH发送，3个波束总功率超过UE最大发射功率且每一发送波束的发射功率均低于终端的最大发射功率。其中，NR-PRACH的优先级高于NR-PUSCH，那么终端将会丢弃NR-PUSCH对应的波束质量较差一个发送波束，从而保证NR-PRACH和NR-PUSCH对应的发送波束的总发射功率限制 在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。其中，当每个目标信道或目标信号仅对应一个发送波束时，可通过调整优先级较低的目标信道或目标信号对应的发送波束的发射功率的方式，保证各发送波束的总发射功率限制在终端的最大发射功率范围内。
方式六、多个目标信道或目标信号可对应至少两个发送波束，即不同目标信道或目标信号对应多个不同的发送波束，若至少两个发送波束对应不同目标信道或目标信号，步骤22还可通过以下步骤实现：将各个目标信道或目标信号对应的发送波束中随机选择的Q个波束确定为第四目标发送波束；通过第四目标发送波束，向基站发送上行信号。其中，Q为正整数，第四目标发送波束的总发射功率低于或等于最大发射功率。
该方式为终端随机选择NR-PUSCH、NR-PUCCH、NR-PRACH和NR-SRS的发送波束，以保证发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
方式七、多个目标信道或目标信号可对应至少两个发送波束，即不同目标信道或目标信号对应多个不同的发送波束，若至少两个发送波束对应不同目标信道或目标信号，步骤23具体包括：分别调整各个目标信道或目标信号对应的每个发送波束的发射功率，直至发送波束的总发射功率低于或等于最大发射功率；通过调整发射功率后的发送波束，向基站发送上行信号。
该方式为终端主动调整NR-PUSCH、NR-PUCCH、NR-PRACH和NR-SRS对应的多个发送波束中部分或全部波束的发射功率，以保证发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
方式八、多个目标信道或目标信号可对应至少两个发送波束，即不同目标信道或目标信号对应多个不同的发送波束，若至少两个发送波束对应不同目标信道或目标信号，步骤24具体包括：按照目标信道或目标信号，将发送波束分为多组；通过时分复用的多组发送波束，分别向基站发送上行信号。其中，每组发送波束的总发射功率低于或等于最大发射功率。
该方式为终端将NR-PUSCH、NR-PUCCH、NR-PRACH和NR-SRS对应的多个波束按照时分方式轮流发送，以保证每组发送波束的总发射功率限制在终端的最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
若目标信道为物理随机接入信道，在步骤22、23或24之后，终端还进一步向基站发送用于指示波束功率爬升暂停的指示信息。这里指的是，当终端放弃或调整NR-PRACH对应的多个发送波束中的一个或多个时，终端将会发送功率爬升暂停指示信息至高层。
若目标信道为物理上行共享信道和/或物理上行控制信道，或者目标信号为信道探测参考信号，在步骤22、23或24之后，终端还进一步向基站发送携带有波束功率余量的信息。这里指的是，当终端放弃或调整NR-PUSCH、NR-PUCCH和/或NR-SRS对应的多个发送波束中的一个或多个时，终端将会触发功率余量上报并发送功率余量至高层。
本公开实施例的上行多波束功率控制方法中，当目标信道或目标信号对应的多个发送波束的总发射功率超过终端的最大发射功率时，可通过丢弃部分发送波束，或调整各个发送波束的发射功率，或通过多波束时分复用等方式，将总发射功率控制在终端最大发射功率范围内，保证了各个发送波束的正常传输，且进一步保证了目标信道或目标信号的波束传输的可靠性。
