本申请属于通信技术领域,具体涉及一种波束切换方法、装置及存储介质。
背景技术
***移动通信(the 4th generation mobile communication,4G)以后的移动通信***,***支持的工作频段提升至6GHz以上,最高约达100GHz,不仅基站侧支持大规模阵列天线,终端/用户设备(User Equipment,UE)也将支持大规模阵列天线。
现有技术中,针对基站侧的大规模阵列天线,在做波束切换之前,首先进行波束测量,在进行波束测量时,网络会配置参考信号资源集合(RS Resource Set),其中包含至少一个参考信号资源(RS resource)。UE测量每个RS resource的参考信号接收功率(Reference Signal Receiving Power,RSRP)/信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR),并将最优的至少一个测量结果上报给网络,上报内容包括同步信号块资源指示(Synchronization Signals Block ResourceIndicator,SSBRI)或信道状态信息参考信号资源指示(CSI-RS Resource Indicator,CRI),及对应的层1参考信号接收功率(Layer 1 Reference Signal Receiving Power,L1-RSRP)/层1信号与干扰加噪声比(Layer 1 Signal to Interference plus Noise Ratio,L1-SINR)。该报告内容反映了至少一个最优的波束及其质量,供网络确定用来与UE传输信道或信号的波束信息。
针对UE支持大规模阵列天线的情况,在进行波束切换时,若采用现有的 波束测量和切换方式,无法对UE侧的特定面板/波束进行测量和上报,这种场景下如何进行波束切换,目前还没有解决方案。
