本申请主张在2022年02月09日在中国提交的中国专利申请No.202210122881.9的优先权和2022年10月14日在中国提交的中国专利申请No.202211262378.X的优先权,其全部内容通过引用包含于此。
技术领域
本申请属于通信技术领域,具体涉及一种功率控制PC参数的确定方法、装置及终端。
背景技术
当前技术中关于功率控制(Power Control,PC)的意义包括:维持功率(根据终端距离基站的距离远近调整功率,确保信号到达基站的功率接近);提升性能(根据信道变化动态调整功率,实现精确快速功率调节);降低干扰(减少邻通道功率泄露,降低用户间和小区间的干扰,延长电池寿命)。
功率控制的划分如下:
下行功率控制,主要依赖网络侧的配置和实现;
上行功率控制,主要包括:物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的PC,物理上行控制信道(Physical Uplink Control Channel,PUCCH)的PC,探测参考信号(Sounding Reference Signal,SRS)的PC,物理随机接入信道(Physical Random Access Channel,PRACH)的PC;
还包括:功率余量上报(Power Headroom Report,PHR),主要为辅助基站调度;功率缩放(Power scaling/sharing),主要目的为共享功率,保证优先级较高的小区/信道传输。
一方面,第5代(5th Generation,5G)通信系统中引入了新的统一传输配置指示(Transmission Configuration Indicator,TCI)架构,可称之为统一TCI架构(unified TCI framework),即网络使用媒体接入控制层控制单元(Media Access Control Control Element,MAC CE)和/或下行控制信息 (Downlink Control Information,DCI)指示的同一个波束(beam)可以用于多个信道传输,这种beam也可称为公共波束(common beam)。在unified TCI framework中包括联合TCI(joint TCI)和独立TCI(separate TCI)两种模式,是由网络的无线资源控制(Radio Resource Control,RRC)信令来配置的。其中,联合TCI状态指示具体包括:指示某一个TCI状态同时用于上行传输和下行传输;独立TCI状态指示具体包括:指示某一个TCI状态用于上行传输或下行传输。
另一方面,5G中引入了多传输接收节点(multi-TRP,可简称为MTRP)传输,控制信令方面分为单DCI调度和多DCI调度两种情况:
多DCI(multi-DCI,可简称为mDCI)调度:每个发送接收点(Transmission Reception Point,TRP)发送各自的PDCCH,每个PDCCH调度各自的物理下行链路共享通道(Physical Downlink Shared Channel,PDSCH),此时网络为用户设备(User Equipment,UE)配置的多个控制资源集(Control resource set,CORESET)关联到不同的RRC参数CORESET池索引(CORESETPoolIndex),对应不同的TRP;
单DCI(single DCI,可简称为sDCI)调度:由一个TRP发送PDCCH调度一个PDSCH,此时网络为UE配置的多个CORESET不能关联到不同的CORESETPoolIndex。在这种情况下,MAC CE激活最多8个码点(codepoint),其中至少一个码点对应两个TCI状态(TCI state)。当一个DCI中TCI字段(TCI field)指示的codepoint对应两个TCI state且指示有一个TCI state包含“QCL-TypeD”时,意味着调度PDSCH来自两个TRP。
但是,在unified TCI framework中,目前仅仅应用于单TRP场景,尚没有在多TRP场景中应用unified TCI framework时如何确定上行功控参数的方案。
发明内容
本申请实施例提供一种功率控制PC参数的确定方法、装置及终端,能够解决在多TRP场景中应用unified TCI framework时如何确定上行功控参数的问题。

第五方面,提供了一种可读存储介质,所述可读存储介质上存储程序或指令,所述程序或指令被处理器执行时实现如第一方面所述的方法的步骤。
