Description

一种被用于无线通信的节点中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及无线通信中上行功率确定的传输方案和装置。
背景技术
5G无线蜂窝通信网络系统(5G-RAN)在原有LTE(Long-Term Evolution，长期演进)的基础上对UE(User Equipment，用户设备)的上行功率控制进行了增强。相较于LTE，因为5G NR系统没有CRS(Common Reference Signal，公共参考信号)，上行功控所需要的路损(Pathloss)测量需要采用CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)和SSB(SS/PBCH Block，同步信号/物理广播信道块)进行。除此之外，NR系统最大的特点是引入了波束管理机制，终端可以用多个不同的发射和接收波束进行通信，进而终端需要能够测量多个波束所对应的多个路损，其中，确定路损的一种方式是通过DCI(Downlink Control Information，下行控制信息)中的SRI(Sounding Reference Signal Resource Indicator，探测参考信道资源指示)指示到某个关联的下行RS(Reference Signal，参考信号)资源以实现。
在NR R17以及R18的讨论中，终端侧配置多个Panel(面板)的场景已经被采纳，而引入多个Panel所带来的对功率控制的影响也相应的需要被考虑。
发明内容
在NR R17以及R18的讨论中，对终端的发送进行了增强，其中一个重要的方面就是引入了两个Panel，终端可以采用两个Panel同时在两个发送波束上进行发送以获得更好的空间分集增益。然而，上行发送的一个重要的指标是功率控制，现有UE的最大发送功率的确定均基于一个Panel的情况设计，且没有考虑两个Panel之间的发送功率的关系和限制。
针对上述多面板场景下的上行功控的问题，本申请公开了一种解决方案。需要说明的是，在本申请的描述中，只是将多面板作为一个典型应用场景或者例子；本申请也同样适用于面临相似问题的其它场景，例如单面板的场景，或者针对不同的技术领域，比如除了上行功控之外的技术领域，例如测量上报领域，上行数据传输等其它非上行功控领域以取得类似的技术效果。此外，不同场景(包括但不限于多面板的场景)采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下，本申请的任一节点中的实施例和实施例中的特征可以应用到任一其他节点中。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。特别的，对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS36系列、TS38系列、TS37系列中的定义。在需要的情况下，可以参考3GPP标准TS38.211，TS38.212，TS38.213，TS38.214，TS38.215，TS38.321，TS38.331，TS38.305，TS37.355以辅助对本申请的理解。
