具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
本申请的说明书和权利要求书中的术语“包括”以及它的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外，说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一，例如A和/或B，表示包含单独A，单独B，以及A和B都存在三种情况。
在本公开实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
下面结合附图介绍本公开的实施例。本公开实施例提供的一种PH的计算方法和终端可以应用于无线通信***中。该无线通信***可以为采用5G***，或者演进型长期演进(Evolved Long Term Evolution，eLTE)***，或者后续演进通信***。
请参见图1，图1是本公开实施例可应用的一种网络***的结构图，如图1所示，包括终端11和基站12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端侧设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端11的具体类型。上述基站12可以是4G基站，或者5G基站，或者以后版本的基站，或者其他通信***中的基站，或者称之为节点B，演进节点B，或者所述领域中其他词汇，只要达到相同的技术效果，所述基站不限于特定技术词汇。另外，上述基站12可以是主基站(Master Node，MN)，或者辅基站(Secondary Node，SN)。需要说明的是，在本公开实施例中仅以5G基站为例，但是并不限定基站的具体类型。
请参见图2，图2是本公开实施例提供的一种PH的计算方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201、接收路损参考变更指示(Change of path loss reference)。
其中，上述可以是终端接收基站发送的路损参考变更指示，当然，也不排除其他设备发送的可能，例如：其他终端发送。
另外，上述路损参考变更指示用于指示将第一路损参考变更为第二路损参考，其中，上述第一路损参考可以理解为，路损参考变更指示变更前的路损参考，而第二路损参考可以理解为，路损参考变更指示变更的路损参考。
需要说明的是，这里的第一路损参考可以是指一个或者多个路损参考，同理，第二路损参考也可以是指一个或者多个路损参考。例如：第一路损参考可以包括同步信号块(Synchronous Signal Block，SSB)1对应的路损参考、SSB2对应的路损参考、物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的路损参考、物理上行控制信道(Physical Uplink Control Channel，PUCCH)的路损参考和探测参考信号(Sounding Reference Signal，SRS)的路损参考等等中的一个或者多个，则上述路损参考变更指示可以是将这些路损参考信号变更为其他的路损参考。
另外，上述路损参考变更指示可以通过媒体接入控制层控制单元(Medium Access Control Control Element，MAC CE)或物理下行控制信道(Physical Downlink Control Channel，PDCCH)等进行指示，以指示变更终端当前使用的路损参考。
进一步地，终端接收到上述路损参考变更指示可以进行路损参考变更，例如：第一路损参考变更为第二路损参考。
步骤202、采用特定路损参考计算PH，其中，所述特定路损参考包括所述路损参考变更指示变更前的路损参考，或者所述路损参考变更指示变更的路损参考。
其中，上述特定路损参考可以是根据计算PH的时间、触发PHR上报的时间或者生成包括PHR的协议数据单元(Protocol Data Unit，PDU)的时间确定的。例如：可以根据不同的情况，确定特定路损参考包括：路损参考变更指示变更前的路损参考，或者路损参考变更指示变更的路损参考。其中，上述PDU可以是媒体接入控制层(Medium Access Control，MAC)PDU。
另外，上述PH可以包括如下一项或者多项：
终端发送物理上行共享信道(Physical Uplink Shared Channel，PUSCH) 的PH值；
终端发送PUSCH和物理上行控制信道(Physical Uplink Control Channel，PUCCH)的PH值；
终端发送探测参考信号(Sounding Reference Signal，SRS)的PH值。
上述步骤中由于接收到路损参考变更指示，从而在计算PH时，可以选择路损参考变更指示变更前的路损参考，或者路损参考变更指示变更的路损参考，进而可以提高终端上报PH的性能。因为，终端可以根据不同场景要求、或者路损参考变更指示的接收时间等因素选择合适的路损参考计算PH。需要说明的是，本公开实施例中，并不限定步骤201和步骤202的执行顺序，例如：上述路损参考变更指示的接收时间在生成PHR的PDU之后时，步骤201则可以在步骤202之后执行，或者述路损参考变更指示的接收时间在生成PHR的PDU之前时，步骤201则可以步骤202之前执行，其中，附图以该情况进行举例说明。
本公开实施例中，接收路损参考变更指示；采用特定路损参考计算PH，其中，所述特定路损参考包括所述路损参考变更指示变更前的路损参考，或者所述路损参考变更指示变更的路损参考。这样可以提高终端上报PH的性能。
请参见图3，图3是本公开实施例提供的另一种PH的计算方法的流程图，该方法应用于终端，如图3所示，包括以下步骤：
步骤301、接收路损参考变更指示。
步骤302、采用特定路损参考计算PH，其中，所述特定路损参考包括所述路损参考变更指示变更前的路损参考，或者所述路损参考变更指示变更的路损参考。
作为一种可选的实施方式，所述特定路损参考，包括：
最新使用的路损参考。
其中，上述最新使用的路损参考可以是，终端最近使用的路损参考，例如：在未接收到路损参考变更指示时，则最新使用的路损参考为该路损参考变更指示变更前的路损参考，若接收到路损参考变更指示，则最新使用的路损参考为路损参考变更指示变更的路损参考。因为，终端接收到上述路损参 考变更指示后，终端则可以变更路损参考。
这样通过最新使用的路损参考计算PH可以实现终端向基站上报的PHR中的PH与基站计算PH采用的路损参考保持一致，以提高上报的准确性。
在一种可选的实施方式，若所述路损参考变更指示的接收时间在第二时间之前，则所述最新使用的路损参考包括：所述路损参考变更指示变更的路损参考；或者
若所述路损参考变更指示的接收时间在所述第二时间之后，或者所述路损参考变更指示的接收时间与所述第二时间存在重叠，则所述最新使用的路损参考包括：所述路损参考变更指示变更的路损参考，其中，所述终端将所述PHR的中PH值变更为，采用所述变更的路损参考计算的PH。
其中，上述第二时间为所述终端生成包括PHR的PDU的时间或功率余量报告PHR上报时刻前的指定时间。而上述路损参考变更指示的接收时间与所述第二时间存在重叠可以是，指在生成包括PHR的PDU的同时接收到上述路损参考变更指示。
该实施方式中，可以实现若路损参考变更指示的接收时间在所述第二时间之前，则采用路损参考变更指示变更的路损参考计算PH，以及若所述路损参考变更指示的接收时间在所述第二时间之后，或者所述路损参考变更指示的接收时间与所述第二时间存在重叠，则使用路损参考变更指示变更的路损参考PH，以及将PHR的中PH值变更为，采用变更的路损参考计算的PH。从而可以保证终端向基站上报的PHR中的PH与基站计算PH采用的路损参考保持一致，以提高上报的准确性。
作为另一种可选的实施方式，所述特定路损参考，包括：
第一时间或者第二时间对应的路损参考，其中，所述第一时间为所述终端触发PHR上报(PHR trigger)的时间，所述第二时间为所述终端生成包括PHR的PDU的时间或功率余量报告PHR上报时刻前的指定时间。
上述生成包括PHR的PDU的时间可以是生成包括PHR的MAC PDU(PHR MAC PDU Assembly)的时间。
而上述第一时间对应的路损参考可以是根据第一时间确定的，且第一时间存在特定关系的路损参考，例如：所述第一时间对应的路损参考包括：在 所述第一时间使用的路损参考。其中，在第一时间未变更路损参考时，则在所述第一时间使用的路损参考可以包括：在第一时间之前使用的路损参考，而在第一时间变更路损参考(例如：第一时间接收到路损变更参考)，则在所述第一时间使用的路损参考可以包括：当前变更的路损参考。
由于在所述第一时间使用的路损参考计算PH，这样可以实现终端向基站上报的PHR中的PH与基站计算PH采用的路损参考保持一致，以提高上报的准确性。
当然，在一些实施方式中，上述第一时间存在特定关系的路损参考也可以是，在第一时间之前使用的路损参考，该情况下，可以不考虑在第一时间是否接收到路损参考变更指示。
而上述第二时间对应的路损参考可以是根据第二时间确定的，且第二时间存在特定关系的路损参考，例如：所述第二时间对应的路损参考包括：在所述第二时间使用的路损参考，或者在所述第二时间之前最新使用的路损参考。
其中，上述在所述第二时间之前最新使用的路损参考可以是，在第二时间之前终端最近使用的路损参考，例如：在第二时间之后或者在第二时间时接收到路损参考变更指示，则在第二时间之前终端最近使用的路损参考为路损参考变更指示变更前的路损参考。
由于使用在所述第二时间使用的路损参考，或者在所述第二时间之前最新使用的路损参考，这样可以实现终端向基站上报的PHR中的PH与基站计算PH采用的路损参考保持一致，以提高上报的准确性。
一种可选的实施方式，若所述路损参考变更指示的接收时间在所述第二时间之前，则所述第二时间对应的路损参考包括：所述路损参考变更指示变更的路损参考；或者
若所述路损参考变更指示的接收时间在所述第二时间之后，则所述第二时间对应的路损参考包括：所述路损参考变更指示变更前的路损参考；或者
若所述路损参考变更指示的接收时间与所述第二时间存在重叠，则所述第二时间对应的路损参考包括：所述路损参考变更指示变更前的路损参考，或者所述路损参考变更指示变更的路损参考。
该实施方式中，可以实现若路损参考变更指示的接收时间在第二时间之前，则采用路损参考变更指示变更的路损参考计算PH，以保证终端向基站上报的PHR中的PH与基站计算PH采用的路损参考保持一致，以提高上报的准确性。
以及还可以实现若路损参考变更指示的接收时间在所述第二时间之后，则采用路损参考变更指示变更前的路损参考计算PH，这样由于不需要使用变更后的路损参考再次计算PH，从而可以提高PHR的上报效率。
另外，还可以实现在上述接收时间与所述第二时间存在重叠，则可以采用路损参考变更指示变更前或者变更的路损参考计算PH，以提高计算PH的灵活性，以适应不同场景或者业务等的需求。
一种可选的实施方式，若所述路损参考变更指示的接收时间在所述第一时间之前，则所述在所述第一时间使用的路损参考包括：所述路损参考变更指示变更的路损参考；或者
若所述路损参考变更指示的接收时间在所述第一时间之后，则所述在所述第一时间使用的路损参考包括：所述路损参考变更指示变更前的路损参考；或者
若所述路损参考变更指示的接收时间与所述第一时间存在重叠，则所述在所述第一时间使用的路损参考包括：所述路损参考变更指示变更前的路损参考，或者所述路损参考变更指示变更的路损参考。
该实施方式中，可以实现若所述路损参考变更指示的接收时间在第一时间之前，则采用路损参考变更指示变更的路损参考计算PH，以保证终端向基站上报的PHR中的PH与基站计算PH采用的路损参考保持一致，以提高上报的准确性。
以及还可以实现若路损参考变更指示的接收时间在所述第一时间之后，则采用路损参考变更指示变更前的路损参考计算PH，这样由于不需要使用变更后的路损参考再次计算PH，从而可以提高PHR的上报效率。
另外，还可以实现在上述接收时间与所述第一时间存在重叠，则可以采用路损参考变更指示变更前或者变更的路损参考计算PH，以提高计算PH的灵活性，以适应不同场景或者业务等的需求。
当然，本实施例中，还可以包括如下步骤：
步骤303、上报PHR，其中，所述PHR包括采用上述特定路损参考计算的PH。
当然，上述PHR还可以包括：小区最大发送功率。上述上报可以向基站上报PHR，或者称作向网络侧上报PHR。
本实施例中，通过上述介绍的多种可选的实施方式，可以实现终端灵活地采用不同的路损参考计算PH，以提高终端上报PH的性能。
下面以图4对上述介绍的多种可选的实施方式进行举例说明：
如图4所示，第一步，UE触发了PHR上报(PHR trigger)，如图4中的t1时间。第二步，UE生成包含该PHR的MAC PDU(PHR MAC PDU Assembly)，如图4中的t2时间，第三步，UE上报PHR(PHR Transmission)，如图4中的t3时间。而图4中的三个路损参考变更指示(Change of path loss reference)接收时间tx可以表示，路损参考变更指示的发送可以存在三种情况，一种是tx在t1之前，另一种是tx在t1之后，且在t2之前，还有一种是tx在t2之后，且t3之前。当然，本公开实施例中，也不排除终端在图4所示的时间范围内接收到多个路损参考变更指示。
在图4所示的情况下，则UE上报的PHR中的PH值采用的路损参考包括以下任意一种：
方法1：最近的使用的路损参考(或者称作最新使用的路损参考)。例如：如图4所示，网络在tx时刻指示UE的PUSCH的路损参考从“路损参考1”变更为“路损参考2”，则UE采用“路损参考2”作为该PUSCH的PH值的计算。例如：(1)如果该tx在t2之前，UE采用该tx时刻指示的变更的新的路损参考计算PH；(2)如果该tx在t2之后或之时，UE采用该tx时刻指示的变更的新的路损参考计算PH(tx)，并将在t2时刻包含的PHR的PH(t2)值修改为tx时刻指示的变更的新的路损参考计算PH(tx)。
方法2：在生成该PHR MAC PDU同时或之前最近的使用的路损参考(或者可以称作：在所述第二时间使用的路损参考，或者在所述第二时间之前最新使用的路损参考，其中，第二时间为生成PHR MAC PDU的时间或功率余量报告PHR上报时刻前的指定时间)。如图4所示，网络在tx时刻指示UE 的PUSCH的路损参考从“路损参考1”变更为“路损参考2”：(1)如果tx在t2之前，UE采用该tx时刻指示的变更的新的路损参考计算PH(tx)；(2)如果tx在t2之后，UE仍然采用t2时刻之前的路损参考；(3)如果tx在t2同时，UE仍然采用t2时刻之前的路损参考，或采用tx(即t2)时刻变更的路损参考。)
方法3：触发PHR上报时采用的路损参考(或者称作在第一时间使用的路损参考，其中，第一时间为触发PHR上报的时间)。如图4所示，网络在tx时刻指示UE的PUSCH的路损参考从“路损参考1”变更为“路损参考2”：(1)如果tx在t1之前，UE采用该tx时刻指示的变更的新的路损参考计算PH(tx)；(2)如果tx在t1之后，UE仍然采用t1时刻之前的路损参考；(3)如果tx在t1同时，UE仍然采用t1时刻之前的路损参考，或采用tx(即t1)时刻变更的路损参考。)
采用本公开实施例提供的方法，如果UE的路损参考在PHR触发后，在PHR上报前发生了变更，通过规定UE采用的计算PH值用的路损参考，从而让网络侧和UE侧对于该PH值计算采用的路损参考保持一致。
请参见图5，图5是本公开实施例提供一种终端的结构图，如图5所示，终端500包括：
接收模块501，用于接收路损参考变更指示；
