具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述指定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和”表示所连接对象的至少其中之一，字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是，本申请实施例所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，还可用于其他无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用，所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
为了便于理解本申请实施例，下面先介绍以下技术点：
一、智能表面/超材料表面：
智能表面是一种新兴的技术，有如下多个相关的术语，它们表示的都是类似的技术或者实体，这些术语包括：
大型智能表面(Large Intelligent Surface，LIS)；
智能反射阵列(Smart Reflect Array，SRA)；
可配置反射阵列(Reconfigurable Reflect Array，RRA)；
智能反射表面(Intelligent Reflecting Surface，IRS)；
可重构智能表面(Reconfigurable Intelligent Surface，RIS)。
智能表面技术在多个技术领域有所应用，根据应用场景不同有很多种不同的设计方案。按照器件单元的物理原理分类包含可调谐谐振器(Tunable Resonator)可变电容型、导波(Guided Wave)波导型、元素旋转(Element Rotation)极化型等；按照无线信号输出形式，分为反射型智能表面和透射型智能表面；按照无线信号响应参数分类包括相位控制型智能表面，幅度控制型智能表面和幅度相位联合控制型智能表面；按照响应参数控制分类分为连续控制型和离散控制型；按照控制智能表面幅度和相位的频次或快慢分为静态，半静态/动态控制的智能表面，其中静态的智能表面目前就可以应用到已有系统中，例如，第四代移动通信技术(fourth generation，4G)/第五代移动通信技术(fifth-generation，5G)系统。考虑器件设计和制作的复杂度，学术界普遍选择使用单一无线信号响应参数的离散控制型器件单元进行研究。目前，学术界广泛讨论的智能反射表面(Intelligent Reflecting Surface，IRS)就是一种基于信号反射的相位控制智能表面，通过1比特(bit)的指示信息控制器件单元的反射信号的相位，实现0或π的相位翻转。
得益于不需要射频和基带处理电路，智能表面设备相比与传统无线通信收发设备有几点优势：
(1)智能表面设备有更低的成本和实现复杂度；
(2)智能表面设备具有更低的功耗；
(3)智能表面不会引入额外的接收端热噪声；
(4)智能表面设备厚度薄、重量小，可以实现灵活的部署。
RIS反射单元种类的有以下几种：
(1)可调谐谐振器：一个可变电容器被整合到谐振器中，通过改变频率捷变(frequency-agile)贴片谐振器频率，产生相移。
(2)导波控制法：在这种情况下，到达的空间波被天线耦合到导波上，随后导波相移，再重新发射，形成了一个天线移相器。
(3)圆极化波的旋转技术：利用电磁波的反射规律进行设计。
从是否可动态控制的角度划分，反射阵列/智能表面分为两大类：
(1)静态的反射阵列/智能表面：反射阵列的结构和功能可以是固定的，对于一个角度的入射波，超表面单元导致入射波的幅度、相位、极化方式等特性发生固定的改变，得到相应的反射波。
(2)动态的反射阵列/智能表面：反射阵列的结构和功能是可以控制的，对于一个角度的入射波，可以通过可编程控制使得入射波的幅度、相位、极化方式等特性发生不同的改变，得到相应的反射波。对反射超表面实现可编程控制，须在反射单元中引入开关元件(如二极管等)。PIN二极管是目前控制可重构超表面的常见选择，PIN二极管具备较宽范围的射频阻抗，并且失真低，在微波射频领域具有广泛应用。反射单元中的开关元件使其具有多个不同的状态，并且通过控制开关元件的通断可实现不同状态的切换。开关元件在通、断两种情况下，对应反射单元的结构和性能均有较大变化。即，不同状态的反射单元对入射波的幅度、相位、极化等特性有不同的调控模式。
二、智能表面对信号进行直接调制：
因为智能表面可以直接调控电磁信号的波前和各种电磁参数，例如相位、振幅、频率、甚至极化，而无需复杂的基带处理和射频收发操作，因而智能表面除了可以改变无线信道环境从而增强第三方信号的接收质量之外，还可以被用于对信号进行直接调制。
例如，调整智能表面电磁单元的反射相位/幅度不仅用于最大化入射电磁波的接收信噪比，还可用于LIS本身的信息传输。接收端通过检测智能表面反射信号的相位/幅度变化，来接收智能表面本身的信息。
三、无源智能表面：
由于智能表面由大量的器件单元构成并且没有射频和基带处理能力，因此称此类智能表面为无源智能表面。
四、有源无源结合的智能表面(或有源智能表面)：
由于智能表面由大量的器件单元构成并且没有射频和基带处理能力，所以基站无法分别获得基站到智能表面以及智能表面到终端的信道信息。基站或终端的接收信号由大量的智能表面器件单元的响应信号叠加形成，改变一个或者少量的器件单元的工作状态并不能使接收信号产生明显的变化。一种可能的测量方案是在智能表面中安装少量有源器件单元，使得智能表面能够进行信道测量和反馈；基站使用压缩感知或者深度学习算法从有限的信道信息中推算出合理的智能表面配置参数。基于智能表面的通信系统需要一个高效的信道测量机制，在保证智能表面低复杂度的前提下，尽量提升端到端的信号质量。这种安装了部分有源器件的智能表面具备接收信号甚至发送信号的能力，是一种有源无源结合的智能表面(或有源智能表面)。
五、关于新空口(New Radio，NR)中的同步信号块(Synchronization Signal and PBCH block，SSB)：
参见图1，NR中的一个SSB包括分布在连续的4个正交频分复用(Orthogonal frequency division multiplex，OFDM)符号上的主同步信号(Primary Synchronisation Signal，PSS)，辅同步信号(Secondary Synchronisation Signal，SSS)和物理广播信道(Physical broadcast channel，PBCH)。一个SSB突发集(burst set)周期中包括多个SSB(比如包括8个SSB)，不同的SSB可以对应不同的波束方向。NR支持的SSB burst set周期为5毫秒(ms)、10ms、20ms等。
参见图2，图中示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端21、网络侧设备22和智能表面设备23。其中，终端21也可以称作终端设备或者用户终端(User Equipment，UE)，终端21可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(Ultra-Mobile Personal Computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端21的具 体类型。
网络侧设备22可以是基站或核心网，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base TransceiverStation，BTS)、无线电基站、无线电收发机、基本服务集(BasicServiceSet，BSS)、扩展服务集(ExtendedServiceSet，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、无线局域网(Wireless Local Area Network，WLAN)接入点、无线保真(Wireless Fidelity，WiFi)节点、发送接收点(Transmitting Receiving Point，TRP)、无线接入网节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于指定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是并不限定基站的具体类型。

下面结合实施例1、实施例2和实施例3介绍本申请实施例，其中节点 是RIS。
实施例1：RIS改变/控制第一信号特征来隐式指示RIS的信息
步骤1：基站发送配置消息，配置消息包含一下的一项或多项：
(1)第一信号的配置参数，信号标识相关参数，时频资源，周期或者非周期参数等；
(2)RIS的信号操控/信号调制的参数，RIS状态数量，编码调制方式(差分或者直接调制)，RIS类型(操控信号特征，幅度/相位/极化方向等)，RIS切换时机(在循环前缀(Cyclic prefix，CP)内进行切换或者在符号切换)；
可选的，基站(通过基站与RIS的接口)发送相应的配置信息，指示第一信号的配置参数等。
RIS按照配置信息和RIS的索引或标识(index/ID)编码调制信息，确定第一信号的每一个符号或者每一个发送时机(occasion)对应的转发模式(pattern)。
其中，第一信号配置的符号或者发送时机数量不小于RIS需要传输的编码调制信息的数量。
步骤2：UE检测基站发送的第一信号；
所述第一信号包含了多个符号，或者多个发送时机；
基站使用相同的发送波束发送第一信号，RIS按照上一步骤中确定的转发pattern进行工作。
步骤3：UE根据所述第一信号的特征变化规律，和第一关联关系(RIS的编码调制方式)，确定RIS的信息，例如RIS的index。
UE首先确定UE是否能够发现RIS信号(UE是否能与RIS配对)；
如果可以检测到RIS信号，确定第一信号特征对应的RIS的index(或特征index)。
参见表1，特征变化规律X对应RIS的索引1，特征变化规律Y对应RIS的索引2，特征变化规律Z对应RIS的索引3。
表1
第一信号的特征变化规律 RIS的索引
特征变化规律X 1
特征变化规律Y 2
特征变化规律Z 3
其中，协议定义或基站通知终端第一信号的特征变化规律与RIS的index的关联关系。
可选地，第一信号包括如下至少一项：SSB，CSI-RS，SIB1，DMRS，TRS等或其他信号等。
可选地，所述第一信号的特征包括相位，幅度，极化方式，频率，OAM方式等至少一项随时间变化的特征。
在本申请实施例中，RIS改变/控制第一信号特征的具体方法：
(1)RIS改变/控制第一信号的相位，幅度，极化方式，频率，OAM方式中的至少一项；
(2)RIS通过调整RIS单元关联的二极管开或关，或者为RIS单元施加不同的电压等方式来改变/控制第一信号的相位，幅度，极化方式，频率，OAM方式中的至少一项。
如果小区中增加或减少(激活或者关闭)RIS，则通过接收基站发送的信令来获取所述被激活或者关闭的节点的信息，或者，如果已有RIS与第一信号的特征的关联关系发生变更，则通过小区系统消息变更的方式通知UE，即基站通过寻呼(paging)消息通知UE发生系统消息变更，UE读取系统消息获取变更信息。
可选的，UE上报第一信号的检测结果，该检测结果指示UE是否检测到RIS，RIS index检测是否成功等。
方式1-1：第一信号的特征只在时域上变化。
所述第一信号的特征随时间变化的方式，变化的时间粒度，以及变化周期，以及变化周期的起始位置中的一项或多项，可以是协议定义的或者基站通知终端的。
RIS改变/控制第一信号特征的时间粒度可以是每M(M>＝1)个OFDM符号，每N个(N>＝1)时隙，每K(K>＝1)个SSB周期。其中，SSB周期可以是5毫秒(ms)，10ms，20ms，40ms等等，即每时间粒度可以改变基站的信号特征。
以第一信号为SSB为例，RIS通过改变SSB的信号特征隐式指示RIS的信息。
(1)变化的时间粒度：最快1个SSB突发集(burst set)周期变化一次；
(2)变化周期：4个SSB burst set周期；
(3)第一信号的特征随时间变化的方式：
第一种特征为：4个SSB burst set周期中每个SSB burst set的相位分别为相位1，相位2，相位1，相位2，参见图7a；
第二种特征为：4个SSB burst set周期中每个SSB burst set的相位分别为相位1，相位1，相位2，相位2，参见图7b；
第一种特征和第二种特征可以分别关联到RIS index 1和RIS index 2(或特征index 1和特征index 2)。
这样，UE通过检测SSB携带的相位变化特征就可以确定SSB1/SSB2携带的是哪一种特征，从而确定SSB1/SSB2关联的RIS的index。
方式1-2：第一信号的特征只在频域上变化。
所述第一信号的特征随频域资源不同变化的方式，变化的频域资源粒度，是协议定义的或者基站广播的。
RIS改变/控制第一信号特征的频域资源粒度可以是每M(M>＝1)个子载波，RB，RB bundle，RB组(包含几个RB)；即，每频域资源粒度可以改变基站的信号特征。
方式1-3：第一信号的特征在频域和时域上变化。
在本实施例中，RIS通过改变/控制基站发送的第一信号随时间和频域资源变化的特征，向UE隐式指示RIS相关的信息，如RIS的index。
实施例2：基站面向不同RIS发送的信号中携带RIS信息。
方法2-1：基站有5个SSB，其中SSB2，SSB3和SSB4是基站面向RIS1发送的，SSB 0和SSB 1是另外的两个SSB。
参见图8，基站发送的面向RIS 1的SSB(SSB2，SSB3和SSB4)携带有与RIS1相关的信息，例如SSB2，SSB3和SSB4的PSS或者SSS的初始序列，加扰序列，或者cover code等与RIS 1相关。
其中，初始序列，加扰序列，或者cover code与RIS1的信息的关联关系 可以是协议定义或者基站(例如通过SIB/MIB)指示UE的。
可选地，UE通过检测SSB，确定该SSB关联的RIS或者说该SSB覆盖范围内存在RIS可以使用。
可选地，UE在后续的基于RIS的波束训练中进一步确定UE是否需要RIS辅助。
方法2-2：SSB不携带与RIS1相关的信息，面向RIS发送的CSI-RS、DMRS、MSG2、MSG4或MSGB携带与RIS1相关的信息。
其中，CSI-RS或DMRS的初始序列，加扰序列，或者cover code等与RIS 1相关。

可选地，CSI-RS或DMRS与SSB准共址。
方法2-3：SSB和CSI-RS/DMRS等都携带与RIS1相关的信息。
如果小区中增加或减少RIS，或者小区中已有RIS与第一信号的特征的关联关系发生变更，则通过小区系统消息变更的方式通知UE，即基站通过paging通知UE发生系统消息变更，UE读取系统消息获取变更信息。
实施例3：基站直接指示哪些SSB与RIS关联。
比如，UE接收基站通知的SSB以及SSB关联的RIS的index，例如SSB1与RIS1关联，SSB2与RIS2关联，SSB3不与任何RIS关联；
UE接收基站通知的CSI-RS/DMRS以及CSI-RS/DMRS关联的RIS的index。

可以理解的是，上述三个实施例中的RIS也可以是某种relay，例如层1relay，层2relay，层3relay，或者集成接入和回传(Integrated Access and Bachhaul，IAB)节点。
