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，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。说明书以及权利要求书中，使用“和/或”表示所连接对象至少其中之一。
应理解，本公开实施例的技术方案可以应用于5G系统，或者说新无线(New Radio,NR)系统。在本公开实施例中，终端设备可以包括但不限于移动台(Mobile Station，MS)、移动终端(Mobile Terminal)、移动电话(Mobile Telephone)、用户设备(User Equipment，UE)、手机(handset)及便携设备(portable equipment)、车辆(vehicle)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)、具有无线通信功能的计算机等，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。
本公开实施例中，网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。所述网络设备可以为基站，所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等。在采用不同的无线接入技术的系统中，具有基站功能的设备的名称可能会有所不同。例如在LTE网络中，称为演进的节点B(Evolved NodeB，eNB或eNodeB)，在第三代(3rd Generation，3G)网络中，称为节点B(Node B)等等。
如图1所示，本公开实施例提供一种无线通信方法，所述方法可以由终端设备执行，包括如下步骤：
S101：在处于激活态的BWP由第一BWP切换为第二BWP时，确定闭环功控累加器的输出值。
该实施例中，终端设备可以配置有多个BWP，每个BWP可以采用相同或不同的参数集(numerology)。终端设备的上行BWP和下行BWP可以分别由网络设备进行配置。
一般而言，在同一时刻终端设备可以仅被激活一个下行BWP和一个上行BWP，即：终端设备由第一BWP切换为第二BWP之后，第一BWP处于去激活态、第二BWP处于激活态，此时，终端设备还可以包括有上述第一BWP之外的、其它处于去激活态的BWP。可以理解，终端设备由第一BWP切换为第二BWP之前的最近一段时间内，第一BWP可以是处于激活态，第二BWP处于去激活态。
对于上述第一BWP和第二BWP，参见图2和图3，图2和图3示意性地显示出了两种第一BWP和第二BWP和全载波(overall carrier)的关系示意图。在图2中，第二BWP相对于第一BWP而言，可以是中心频点不变、带宽变化(增加)；在图3中，第二BWP相对于第一BWP而言，可以是中心频点变化、带宽同时变化(增加)；当然，在其他的实施例中，第二BWP相对于第一BWP而言，还可以是中心频点变化、带宽不变等等。
上述闭环功控累加器，可以用来输出闭环功率控制累积值。
可选地，在一个实施例中，第一BWP和第二BWP可以共享使用一个闭环功控累加器。
可选地，在另一个实施例中，第一BWP和第二BWP可以分别采用不同的闭环功控累加器。
S102：根据所述闭环功控累加器的输出值，确定通过所述第二BWP进行上行传输时的实际发送功率。
具体地，确定通过所述第二BWP进行上行传输时的实际发送功率，可以是包括下述三种情况中的一个或多个：
确定通过所述第二BWP进行物理上行共享信道PUSCH传输的实际发送 功率；
确定通过所述第二BWP进行物理上行链路控制信道PUCCH传输的实际发送功率；以及
确定通过所述第二BWP进行探测参考信号SRS传输的实际发送功率。
可选地，在一个实施例中，确定通过所述第二BWP进行PUSCH传输的实际发送功率时，可以根据终端设备的最大发射功率，以及，PUSCH频域资源数目；路径损耗(pathloss)补偿因子；路损测量值；PUSCH调制与编码策略(Modulation and Coding Scheme，MCS)有关的功率调整量；以及上述闭环功控累加器的输出值，确定出进行PUSCH传输的实际发送功率。
确定通过所述第二BWP进行PUCCH传输的实际发送功率、以及通过SRS传输的实际发送功率，与上述实施例中通过PUSCH传输的实际发送功率计算过程类似，在此不再赘述。
通过本公开实施例提供的无线通信方法，终端设备在BWP切换时，确定闭环功控累加器的输出值，然后根据所述闭环功控累加器的输出值，即可确定上行传输时的实际发送功率，实现了在BWP切换时实际发送功率的确定，可以提高通信的有效性以及效率。
对于上述实施例中提到的闭环功控累加器，可以是由所述第一BWP和所述第二BWP共享，在这种情况下，上述共享的闭环功控累加器在处于激活态的BWP由所述第一BWP切换为所述第二BWP时可以被重置，具体可以是重置为默认值，或者称作是对上述共享的闭环功控累加器进行初始化操作。
另外，上述第一个实施例中提到的闭环功控累加器，可以是所述第二BWP的闭环功控累加器，此时所述第二BWP的闭环功控累加器与所述第一BWP的闭环功控累加器不同，即第一BWP和第二BWP可以分别采用不同的闭环功控累加器。在这种情况下，所述第二BWP的闭环功控累加器，在处于激活态的BWP由所述第一BWP切换为所述第二BWP时，对所述第二BWP的闭环功控累加器开始进行功控命令累加，不进行上述实施例中的初始化操作。
如前所述，终端设备可以配置有多个BWP，一般而言，在同一时刻终端设备对应一个激活态的BWP和一个或多个去激活态的BWP。如图4所示， 本公开实施例还提供一种无线通信方法，该方法可以由终端设备执行，包括如下步骤：
S401：确定第二BWP的实际功率余量；和/或，确定第一BWP的虚拟功率余量，其中，所述第二BWP为激活态，第一BWP为去激活态。
本实施例可以在处于激活态的分BWP由第一BWP切换为第二BWP时，确定第二BWP的实际功率余量；和/或，确定第一BWP的虚拟功率余量，即确定第二BWP的实际功率余量以及第一BWP的虚拟功率余量至少其中之一。另外，本实施例也可以在其它的时间段内，执行确定第二BWP的实际功率余量；和/或，确定第一BWP的虚拟功率余量的操作。
通过本公开实施例提供的无线通信方法，终端设备可以确定激活态的第二BWP的实际功率余量；确定去激活态的第一BWP的虚拟功率余量；或者是同时确定激活态的第二BWP的实际功率余量和去激活态的第一BWP的虚拟功率余量，实现了功率余量(包括上述实际功率余量和虚拟功率余量，下同)的确定。另外，终端设备在确定出功率余量之后，还可以把确定出的功率余量上报给网络设备，进而使网络设备进行相应的功率调配，可以提高通信的有效性以及效率。
可选地，在一个实施例中，在确定第二BWP的实际功率余量时，可以首先确定所述第二BWP的实际发送功率；然后根据所述第二BWP的第二最大允许发送功率和所述实际发送功率的差值，确定所述实际功率余量。本申请实施例在此示出了第二BWP的实际功率余量的一种具体实现方式。当然，应理解，第二BWP的实际功率余量可以采用其它的方式实现，本申请实施例对此不作限制。
可选地，在一个实施例中，确定第二BWP的实际发送功率时，可以根据所述第二BWP的闭环功控累加器的输出值，确定所述实际发送功率，其中，所述第二BWP的闭环功控累加器可以与所述第一BWP的闭环功控累加器不同，即第一BWP和第二BWP分别采用不同的闭环功控累加器。在这种情况下，所述第二BWP的闭环功控累加器，在处于激活态的BWP由所述第一BWP切换为所述第二BWP时，对所述第二BWP的闭环功控累加器开始进行功控命令累加。
