Description
本申请涉及无线通信系统中的方法和装置,尤其是涉及支持多天线传输的无线通信系统中的方法和装置。
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),配置多根天线来获得额外的空间自由度。多根天线通过天线虚拟化可以形成不同的天线端口,不同的天线端口上可以发送相同或不同的数据来提高传输可靠性或传输效率。NR系统中,UE侧可支持的天线端口数已达到4。
在NR系统中,UE侧的不同天线端口之间的关系分为非相干(nonCoherent),部分非相干(partialNonCoherent)和完全相干(fullCoherent)三类。非相干和部分非相干的天线端口之间不能进行预编码操作,因此UE在进行低秩的上行传输时只会用到部分天线端口。
发明内容
根据NR R(Release)15中的定义,当用于发送PUSCH(Physical Uplink Shared Channel,物理上行共享信道)的非零功率天线端口的数量小于PUSCH配置的天线端口的总数时,UE不能用满功率来发送PUSCH。这一制约因素保证了单根天线不能满功率发送的UE的正常工作,但同时也限制了单根天线能够满功率发送的UE的性能。如何根据UE的能力来优化其发送功率是需要解决的问题。发明人通过研究发现,在一个UE配置的多个天线面板(panel)的情况下,上述问题会更加复杂。
