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，尤其涉及无线通信系统中和CSI(Channel Status Information，信道状态信息)有关的方案和装置。
背景技术
传统的无线通信中，UE(User Equipment，用户设备)上报可能包括多种辅助信息中的至少之一，例如的CSI，波束管理(Beam Management)相关的辅助信息，定位相关的辅助信息等等。其中CSI包括CRI(CSI-RS Resource Indicator，信道状态信息参考信号资源指示)、RI(Rank Indicator，秩指示)、PMI(Precoding Matrix Indicator，预编码指示)或CQI(Channel quality indicator，信道质量指示)中的至少之一。
网络设备根据UE的上报为UE选择合适的传输参数，例如驻留小区、MCS(Modulation and Coding Scheme，调制编码方案)、TPMI(Transmitted Precoding Matrix Indicator，发送预编码矩阵指示)，TCI(Transmission Configuration Indication，发送配置指示)等参数。此外，UE上报可以被用于优化网络参数，例如更好的小区覆盖，根据UE位置开关基站等等。
在NR(New Radio，新无线)系统中，CSI上报的优先级被定义，所述优先级被用于确定是否为相应CSI上报分配CPU(CSI Processing Unit，CSI处理单元)资源以进行更新，或者是否放弃更新相应的CSI上报。
发明内容
传统的PMI反馈方式会带来大量的开销。在NRR(release)18中，基于AI(Artificial Intelligence，人工智能)/ML(Machine Learning，机器学习)的CSI上报被立项。申请人通过研究发现，基于ML/AI的CSI计算和传统的CSI计算有很大差异，两者需要不同的处理能力，对处理单元的占用也有不同的需求。因此当基于ML/AI的CSI上报技术被引入后，UE将如何确定基于ML/AI的CSI上报需要占用的处理单元的数量，是需要解决的问题。
针对上述问题，本申请公开了一种解决方案。需要说明的是，虽然本申请的大量实施例针对AI/ML展开，本申请也适用于其他方案，例如传统的基于码本的方案。此外，不同场景(包括但不限于基于AI/ML的方案和基于码本的方案)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，本申请的第一节点中的实施例和实施例中的特征可以应用到第二节点中，反之亦然。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。
作为一个实施例，对本申请中的术语(Terminology)的解释是参考3GPP的规范协议TS36系列的定义。
