Description
本申请要求于2024年7月11日提交国家知识产权局、申请号为202410931304.3、发明名称为“一种被用于无线通信的节点中的方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
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的传输的方案和装置。
多天线技术是3GPP(3rd Generation Partner Project,第三代合作伙伴项目)LTE(Long-term Evolution,长期演进)系统和NR(New Radio,新无线电)系统中的关键技术。通过在通信节点处,比如基站或UE(User Equipment,用户设备)处,配置多根天线来获得额外的空间自由度。多根天线通过波束赋型,形成波束指向一个特定方向来提高通信质量。多天线系统提供的自由度可以用来提高传输可靠性和/或吞吐量。由于多天线形成的波束都比较窄,通信双方需要将波束对齐来提供通信质量。从NR(New Radio,新无线)R(Release)15开始,3GPP引入了波束失败检测和恢复的机制,尽快发现波束失步并恢复波束对齐,降低波束失步对系统性能的影响。
伴随新技术的采用,天线数量的增加,应用场景的多样化和对系统性能要求的提高等因素,传统的测量和波束失败恢复方式会带来大量的冗余开销。因此在NR R(release)18中,AI(Artificial Intelligence,人工智能)/ML(Machine Learning,机器学习)技术的研究被立项,来探讨其对系统性能和系统设计的影响。和传统的处理方式相比,AI/ML具有基于训练和需要部署等特性。
申请人通过研究发现,当AI/ML功能被引入后,现有的测量机制和候选资源的选择方案可能都无法适应AI/ML的需求。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是针对AI/ML展开的,本申请也适用于其他方案,例如传统的候选资源的选择方案。此外,不同场景(包括但不限于基于AI/ML的方案和传统的候选资源的选择方案)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。
