具体实施方式
下面结合附图和实施例对本申请进行说明。
在NTN系统中，卫星具有移动性，波束(Beam)或小区(Cell)的覆盖区域会随着卫星运动而移动，波束不断移动或者切换，使得终端发送上行信号的链路质量不断变化，且不同类型的卫星的波束对链路质量的影响也有所不同。由于终端的发射功率无法动态适应移动或切换的波束、功率控制灵活性差，严重影响了通信质量和可靠性。本实施例针对NTN中波束移动与切换的情况，由服务节点预配置功率参数集合并指示给终端，在此基础上实现对终端发射功率的灵活指示与控制。
图1为一实施例提供的一种功率控制方法的流程图。该功率控制方法可应用于服务节点，例如应用于基站。如图1所示，本实施例提供的方法包括步骤110和步骤120。
在步骤110中，发送配置信息，所述配置信息用于指示N组功率参数集合，其中，N为正整数。
在步骤120中，接收上行数据，所述上行数据的发射功率由终端根据所述配置信息确定。
本实施例中，服务节点预配置了N组功率参数集合并通过配置信息指示给 终端，这N组功率参数集合供终端在不同参考信号或者载波关联的波束下进行选择和应用，作为计算上行数据发射功率的依据。在指示N组功率参数集合的过程中，还可以指示N组功率参数集合与不同波束、不同参考信号或不同载波之间的对应关系，例如，第一组功率参数集合对应于第一波束，第二组功率参数集合对应于第二波束。在终端采用第一波束(将第一波束作为服务波束)发送上行数据的情况下，可以基于第一组功率参数集合计算该第一波束上对应的发射功率；在终端采用第二波束(将第二波束作为服务波束)发送上行数据的情况下，可以基于第二组功率参数集合计算该第二波束上对应的发射功率。此外，如果发生服务波束切换，例如服务波束由第一波束切换为第二波束，则终端也可以根据配置信息的指示，改变所采用的功率参数集合，以准确计算发射功率，适应波束的移动或切换。
服务节点通过将预配置的功率参数集合通过配置信息指示给终端，为终端计算发射功率提供依据，在此基础上实现对终端发射功率的灵活指示与控制，提高功率控制的可靠性。
在一实施例中，N组功率参数关联于L个波束，其中，L为正整数。
本实施例中，N组功率参数与L个波束之间具有关联关系。L个波束中，被用于传输上行数据的即为服务波束。终端根据服务波束即可选用相应的一组功率参数，据此计算上行数据的发射功率。N组功率参数与L个波束可以按照一定的顺序依次对应，也可以具有其他的关联关系，并由服务节点指示给终端。
在一实施例中，每个波束由如下之一表示：一个参考信号；一个载波；一个空域传输资源；其中，所述空域传输资源包括如下之一：天线端口；码本；传输层。
本实施例中，服务节点生成不同的参考信号或者不同的载波，其中，生成的载波可以包括锚定载波(Anchor Carrier)和非锚定载波(Non-Anchor Carrier)，锚定载波用以发送窄带主同步信号、窄带辅同步信号、窄带物理广播信道或窄带系统信息块等。不同的波束可以通过关联的不同参考信号或者不同载波来区 分，例如，服务节点将不同参考信号或不同载波的索引值指示给终端，用于区分不同波束，从而实现对不同波束的功率参数集合的准确指示。不同的波束也可以通过不同的空域传输资源来区分，例如，不同的波束对应于不同的天线端口、不同的码本或者不同的传输层。
在一实施例中，所述配置信息通过如下信令之一发送：广播消息；无线资源控制(Radio Resource Control，RRC)信令；介质访问控制层控制单元(Medium Access Control，Control Element，MAC CE)信令；下行控制信息(Downlink Control Information，DCI)。通过上述的信令发送配置信息，实现N组功率参数集合的高效指示。
在一实施例中，所述功率参数集合包括以下至少之一：功率基准值；部分功率补偿因子；测量路损的下行参考信号；下行参考信号发射功率；功率偏移。
本实施例中，每组功率参数集合中都可以包括以下参数的一种或多种：功率基准值(PO_PUSCH)；部分功率补偿因子(α)；下行参考信号发射功率(rs-power)；载波的功率偏移(rs-PowerOffsetNonAnchor)；测量路损的下行参考信号。终端也可以通过其他方式获得这些功率参数，例如是协议中预定义的、根据服务节点指示的其他信息与功率参数集合的映射关系隐含获得的等。终端根据这些功率参数，可以在功率基准值的基础上，对功率进行补偿、偏移调整等，实时计算在服务波束下对应的发射功率。
其中，不同的波束下，用于测量路损的下行参考信号可能是不一样的，也可能是一样的，但对应的发送功率或者固定功率偏移不同。服务节点通过预配置并指示用于测量路损的下行参考信号，可以明确哪个波束作为服务波束，为终端应用相应的功率参数集合提供可靠的依据。
在一些实施例中，服务节点可以通过系统信息块(System Information Blocks，SIB)或(Physical Broadcast Channel，PBCH)向终端指示功率参数集合的索引，从而指示终端需要在N组功率参数集合中采用哪组功率参数集合。
在一些实施例中，服务节点可以通过SIB中的比特位域来指示波束对应的 载波索引值，不同载波关联于不同波束，因此，终端可以根据载波(索引值)与波束之间的映射确定不同波束上的Anchor或Non-Anchor载波的功率偏移值。
在一实施例中，还包括：
步骤130：根据服务波束切换信息向所述终端发送功率更新指示信息；或者，
步骤140：根据上行测量结果向所述终端发送功率更新指示信息。
本实施例中，服务波束可以为用于在服务节点和终端之间的数据传输的波束，服务波束切换指在L个波束中，用于数据传输的服务波束发生了切换。例如服务波束由波束1切换到波束2，则服务节点向终端发送功率更新指示信息，以指示终端在服务波束切换的情况下，应用波束2关联的功率参数集合来计算发射功率。或者，在服务波束切换的情况下，服务节点会针对新的服务波束(波束2)进行上行信道的路径损耗的测量，根据上行测量结果，向终端发送功率更新指示信息，以指示终端在路径损耗发生变化的情况下，需要对所采用的功率参数集合根据实际情况进行调整，例如，功率参数集合中的部分功率补偿因子α＝0.7，服务节点根据对路径损耗的上行测量结果，向终端发送功率更新指示信息，终端可以据此将部分功率补偿因子调整为α＝1。
在一实施例中，所述配置信息还用于指示N组功率参数与L个波束之间的关联关系。
本实施例中，服务节点通过配置信息还可向终端指示N组功率参数与L个波束之间的关联关系，即指示第i(1≤i≤N)组功率参数集合与第j(1≤j≤L)个波束的关联关系，从而终端可以唯一确定在不同的服务波束下采用哪组功率参数集合。
在一实施例中，还包括：
步骤101：发送第一分组指示信息，所述第一分组指示信息包括分组参考点信息，每个分组参考点对应于一个分组。
本实施例可以将网络中的终端划分为一个或多个分组，然后按照分组发送配置信息，从而节省信令开销和网络资源，提高指示功率参数集合的效率。服 务节点向终端发送第一分组指示信息，终端根据第一分组指示信息可以确定所属的分组，并根据配置信息的指示，确定其所属的分组应采用哪一组功率参数集合。
本实施例中，第一分组指示信息包括分组参考点信息，分组参考点信息例如为作为分组参考点的终端的所在位置、终端标识等。例如，服务节点网络覆盖范围内有多个终端，其中，终端A、终端B、终端C作为分组参考点，第一分组指示信息包括终端A、终端B和终端C的所在位置，服务节点将第一分组指示信息发送给各个目标终端，则目标终端可以据此确定自身属于终端A的分组、终端B的分组或者终端C的分组。例如，目标终端根据接收到的第一分组指示信息，确定在分组参考点中距离最近的终端为终端B，则目标终端确定自身属于终端B的分组；目标终端接收到配置信息后，可以采用终端B的分组对应的功率参数集合计算发射功率。
在一实施例中，还包括：
步骤102：发送第二分组指示信息，所述第二分组指示信息包括区域标识，每个区域对应于一个分组。
本实施例可以将网络中的终端划分为一个或多个分组，然后按照分组发送配置信息，从而节省信令开销和网络资源，提高指示功率参数集合的效率。服务节点向终端发送第二分组指示信息，终端根据第二分组指示信息可以确定所属的分组，并根据配置信息的指示，确定其所属的分组应采用哪一组功率参数集合。
本实施例中，第二分组指示信息包括区域标识。例如，服务节点网络覆盖范围划分为区域A、区域B、区域C，每个区域的终端划分为同一个分组。第二分组指示信息包括区域A、区域B或区域C的区域标识，服务节点将第二分组指示信息发送给各个目标终端，则目标终端可以据此确定自身属于域A、区域B或区域C的分组。例如，目标终端根据接收到的第二分组指示信息，确定自身处于区域B中，则目标终端确定自身属于区域B的分组；目标终端接收到配置 信息后，可以采用区域B的分组对应的功率参数集合计算发射功率。
在一实施例中，步骤120具体包括：分别向各所述分组发送相应分组所关联的功率参数集合。
本实施例中，服务节点按照分组参考点或区域，分别向每个分组发送配置信息，从而指示每个分组关联的功率参数集合，而无需向网络覆盖范围内的每个终端都发送配置信息，从而节省信令开销和网络资源，提高指示功率参数集合的效率。
