Description

用于无线通信的方法和装置 技术领域
本申请涉及无线通信系统中的方法和装置，尤其涉及无线通信系统中的CSI(Channel Status Information，信道状态信息)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(Channel Status Information，信道状态信息)，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报告的优先级被定义，所述优先级被用于确定是否为相应CSI报告分配CPU(CSI Processing Unit，CSI处理单元)资源以进行更新，或者是否丢弃(drop)相应的CSI报告。
发明内容
随着天线数量的增加，传统的PMI反馈方式会带来大量的冗余开销，因此，在NR R(release)18中，基于AI(Artificial Intelligence，人工智能)或者ML(Machine Learning，机器学习)的CSI压缩被立项。在传统的多天线系统中，CQI的计算通常以PMI为条件；例如基于UE(User Equipment，用户)上报的PMI被基站采纳的假设下，CQI被计算出。申请人通过研究发现，传统的CSI上报支持基于子带(subband)的PMI上报，基于AI或者ML的CSI压缩如何支持类似的功能将会面临挑战。
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，本申请也适用于基于传统的例如基于线性信道重构的方案；尤其是考虑到，具体的信道重构算法很可能是非标准化的或者是硬件设备商自行实现的。进一步的，采用统一的UE上报的方案能够降低实现复杂度，或者提高性能。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。
在需要的情况下，对本申请中的术语的解释可以参考3GPP(3rd Generation Partner Project，第三代合作伙伴项目)的规范协议TS37系列以及TS38系列的描述。
