智能表面(Reconfigurable Intelligent Surface(s),RIS)是一种新兴的人造材料设备。RIS器件单元可以动态地/半静态地调整自身的电磁特性影响入射到RIS器件单元的电磁波的反射/折射行为,使得转发信号(反射信号或者透射/折射信号)的电磁参数(相位或者幅度或者极化方向)产生变化。RIS设备由大量RIS器件单元构成,通过控制各个RIS器件单元的电磁特性状态,各个RIS器件单元对电磁信号的反射/折射行为在空间上互相叠加,实现波束扫描/波束赋形等功能。
RIS设备包含控制模块,通过无线或者有线接口与基站进行交互。RIS可以接收来自上游基站(包括宿主基站(donor gNB),或者上一跳节点父节点(parent node))的控制,即基站可以控制RIS的传输参数,例如RIS和基站间或者RIS和UE间的接收/发送波束等,以提高RIS的工作效率。

NR Uu波束对准:
以下行波束对准为例,波束对准大致分为两个阶段。第一个阶段是在UE接入网络的时候,初步训练基站到UE的初始传输波束。第二阶段是在UE建立连接之后,训练基站到UE的精细收发波束对,第二阶段的波束训练主要通过信道状态信息参考信号(CSI Reference Signal,CSI-RS)的测量和信道状态信息(Channel State Information,CSI)反馈来完成。
对于第一阶段,基站周期性的发送同步信号/物理广播信道信号块(或同步信号块)(Synchronization Signal and PBCH block,SSB),并在每个SSB发送周期以波束扫描的方式发送一组SSB。UE测量SSB携带的参考信号,上报接收能量较高SSB索引(index),以便基站确定其发送波束。UE根据协议规定的规则上报SSB index,每个SSB对应一组物理随机接入信道(Physical Random Access Channel,PRACH)资源,UE在相应的PRACH资源上发送初始接入的序言(preamble),代表UE上报相应的SSB index。对于第二阶段,Rel-15NR Uu CSI获取流程如图3所示。基站进行CSI上报相关参数配置,触发CSI上报(所述‘触发’仅针对半持续性(semi-persistent)或周期性(aperiodic)的CSI上报),
UE根据基站配置信息进行CSI测量和上报,基站根据UE上结果调整上下行波束等传输参数。其中,每个CSI上报配置指示了CSI上报的类型(CSI quantity),其中包括CSI参考信号资源标识(CSI-RS Resource Index,CRI)、SSB index等指示波束的参数,还包括其他参数类型预编码矩阵标识(Precoding matrix index,PMI)、秩标识(rank index,RI)、信道质量标识(Channel quality index,CQI)、层1参考信号接收功率(Layer 1 reference signal received power,L1-RSRP)、信号与干扰加噪声比(Signal to Interference plus Noise Ratio,SINR)等。
另外,对于基站/UE侧的波束训练,基站/UE可以自主地选择训练波束。
相关技术中,在通过RIS等中继设备连接在基站与终端之间,进行信息转发的场景下,RIS设备可以用于终端信号增强。例如:在低速率业务时,终端可以直接与基站进行通信,在高速率业务时,终端可以在RIS设备的辅助下增强信号质量,提供通信速率。因此,在调度RIS设备为终端服务之前,网络要对RIS设备的接收/转发波束进行训练,保证基站-RIS-终端的级联信道的信道质量。但是,由于RIS设备没有基带信号处理能力,只能进行模拟波束的转发,因此,相关技术中的波束训练方法并不适用于有RIS设备存在的场景。
本申请实施例中,定义了有RIS设备存在的场景下的波束训练方法,使得中继设备(即本申请实施例中的第一设备)能够基于第一参数和/或第二参数参与网络侧设备、中继设备和终端之间的波束训练,通过该波束训练过程,可以确定中继设备的出射波束、出射角、入射波束、入射角中的至少一项。
需要说明的是,本申请实施例中的出射波束等同于发送波束、发送角、出射角;本申请实施例中的入射波束等同于接收波束、接收角、入射角。
本申请实施例中的训练波束又可以称之为“管理(manage)或扫描或遍历波束”,训练波束的过程可以是波束或者波束相关的参数进行切换,以从中确定最终的波束。
