用于无线通信的方法和装置 技术领域
本发明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报告的方案和装置。
背景技术
传统的无线通信中,基站根据UE(User Equipment,用户设备)上报的CSI(Channel Status Information,信道状态信息)为UE选择合适的传输参数,例如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。
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
为了进一步提高MIMO(Multi Input Multi Output,多输入多输出)系统的性能,CSI方案被持续优化。发明人通过研究发现,随着更加复杂的调度方案或者CSI报告方法被提出,现有的CSI报告的优先级的确定方法可能不再适用。
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NR中的CSI报告的优先级展开说明,本申请也能用于其他系统的CSI的优先级。进一步的,采用统一的CSI报告的优先级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。
