技术领域
本申请属于通信技术领域，具体涉及一种无线通信方法、装置和设备。
背景技术
随着无线通信技术的发展，用户对无线通信速率和质量的要求也日益提高。尤其，对于例如VR业务，AR业务、视频业务等存在热点业务覆盖增强业务场景中，仅使用基站的波束赋形技术，不足以给终端提供足够的通信速率。因此，在上述情况下，还需要在无线通信网络中引入例如智能表面(Intelligent Surfaces)的辅助节点，增强终端接收信号强度。
尤其，在无线通信过程中，由于终端运动或者通信环境中的物体发生变动，基站到终端的等效信道是随时间变化的。因此，预先配置的基站到终端的频域资源可能在一段时间后处于频率选择性深衰落的情况。因此，通过智能表面改善频率选择性深衰落问题，是十分必要的。
然而，智能表面的信道估计流程相比于传统信道估计更为复杂，其难以做到实时更新智能表面的转发波束状态。并且，由于无线信道的多径相位和幅度的变化是随机的、随时间慢变的、受终端和环境物体的移动以及变化速度影响的，因此，在频域上，如果一段资源块陷入了频率选择性衰落的情况，那么在之后的一段时间内，该段资源块将会一直处于频率选择性衰落状态，并导致通信质量变差，直至多径信道变化到其他情况为止。由于基于智能表面的信道估计流程的时间长，并且需要额外时间根据信道估计结果更新智能表面的工作状态，因此根据过期的信道信息得出的智能表面工作状态不能达到最优的信道增强的性能。
因此，如何控制智能表面及时有效、低计算复杂度地对无线通信过程中频率选择性衰落情况进行调整，成为了本领域亟待解决的当务之急。

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，而不用于描述特定的顺序或先后次序。应该理解这样使用的术语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/或”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。
为方便对本申请实施例的理解，下面对本申请实施例中所涉及的部分术语进行解释。
1、智能表面
智能表面(Reconfigurable Intelligent Surface，RIS)是一种辅助通信设备。如图1所示， 智能表面之上设有多个的器件单元，该RIS器件单元的尺寸通常为亚波长量级，即其尺寸小于工作频点对应的波长。RIS器件单元规律地排列在平面或者曲面之上，构成RIS器件单元阵列。其中，每个RIS器件单元包含一个独立可控元件，由后台的RIS控制模块进行控制。在RIS控制模块的控制下，RIS器件单元可以动态地或半静态地调整自身的电磁特性，由此影响入射到RIS器件单元的电磁波的反射或折射行为。因此，智能表面可以对电磁信号的反射信号或折射信号进行操控，并由此实现波束扫描或波束赋形等功能。由于智能表面仅包含无源器件单元，因此其转发信号与信源发射信号保持信号相关性，可以在接收侧实现多径信号的相干叠加。在由智能表面辅助的无线通信网络中，通过波束训练或者模拟波束赋形，可以将智能表面的转发波束对准终端或者终端所在区域，通过及时改变智能表面转发波束的状态，则可以改善通信链路的频率深衰落情况。特别的，对于其他具有无线信号相干转发的设备，例如backscatter，相干转发中继等，同样可以调整转发信号的状态来改善通信链路的频率选择性深衰。
2、基于智能表面的波束控制原理
如图2所示，基于智能表面的波束控制原理具体如下。
以相位控制型智能表面为例，器件单元(m，n)的理想控制相位为：

其中，
Figure PCTCN2022094747-appb-000002
分别为基站，终端，以及RIS器件单元(m，n)的坐标向量。如果终端与智能表面的相对位置满足远场辐射条件，则智能表面到终端的信号近似为平行信号，即
Figure PCTCN2022094747-appb-000003
在满足远场辐射条件时，基站与智能表面之间也可以进行相应近似操作。
其中，对于1bit的离散相位控制型智能表面，通过离散化处理可以将理想补偿相位映射离散相位上，例如：
Figure PCTCN2022094747-appb-000004
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。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，但是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。
图3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11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11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：智能手表、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11的具体类型。网络侧设备12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 Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，第一设备S)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point，TRP)或领域中其他某个合适的术语，只要达到相同的技术效果，基站不限于特定技术词汇，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。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的无线通信、装置和设备进行详细地说明。
在相关技术中，5G NR协议提供了模拟波束扫描的功能。其基本流程是基站依次在不同时间段发送用不同方向的波束发送信号，终端用固定的接收波束接收信号，并选择最合适的发送波束上报给基站。
使用5G NR定义的波束扫描流程或者针对智能表面设备设计的信道估计和波束赋形流程可以使智能表面的转发信号波束对准终端，达到预期的接收效果。例如，可以使终端在工作频段内接收信号能量最大化。
但是，如图4所示，在无线通信过程中，由于终端运动或者通信环境中的物体发生移动，基站到终端的等效信道是随时间变化的。因此，预先配置的基站到终端的频域资源可能在一段时间后处于频率深衰落的情况。
智能表面设备为终端提供了一部分多径信号，并且可以控制多径信号的相位和强度。通过改变部分多径信道的相位或者强度，可以降低频率选择性衰落对数据传输的影响。通信系统在已知全部的信道信息时，基站可以调整智能表面的转发波束的状态，使终端在被调度的频率资源上接收信号强度最大(即智能表面的转发信号与多径环境中的普通物体的反射/散射信号正向叠加)。因此，在引入智能表面后，通过控制多径信道中部分多径的相位，可以改善被调度的频率资源的频率选择性衰落。
关于基站对智能表面的控制方式，相关技术中试图使用闭环调度或者开环跳频分集的技术方案对智能表面进行控制。闭环调度是指上行或者下行信道测量为终端调度非频率选择性深衰落的频率资源。开环跳频分集是在未知当前信道情况的时候通过跳频的方式将传输数据映射在不同的两块时频资源上来降低遇到频率选择性深衰落的概率提升数据传输的鲁棒性。
然而，基站或者终端的信号相位发生变化时，会影响多径环境中所有多径的相位变化。因此，现有通信系统无法实现单独控制部分多径的目的。相应地，相关技术中使用的闭环调度或者开环跳频分集的技术方案难以高效避免频率选择性深衰落。
此外，为了实现准确的智能表面转发波束的控制，基站和终端需要进行复杂的信道测量和反馈操作，再按照测量结果计算智能表面的工作状态并且发送给智能表面，还要为终端调度对应的频率资源。这一套闭环控制流程的时间开销要比5G NR系统的闭环控制流程更高，复杂度也更高。系统的数量传输效率受到影响。
尤其，在多用户场景中，智能表面的转发波束的覆盖区域中存在多个终端需要服务。由于智能表面只能实现模拟波束转发，多用户往往需要通过时分复用或者频分复用的方式共享通信资源。同一区域内的多个终端的多径环境存在差异，频率资源调度结果也不尽相同，因此对智能表面的转发波束的相位要求也有所不同。智能表面很难同时满足多用户的通信需求。即使通过闭环的信道测量获得多用户的信道信息，系统可能无法确定一个智能表面的工作状态同时满足所有多用户的信道需求。如图5所示，在多用户的场景中(例如图5中智能表面覆盖区域内包括终端1、终端2和终端3的场景)，各个终端对转发波束的相位要求也各有不同。智能表面的转发波束是模拟波束，无法同时保证多个终端的最优波束，因而影响了无线通信系统的整体容量。
如图6所示，为了克服上述问题，本申请实施例提供了一种无线通信方法。本申请实施例提供的无线通信方法包括以下的S101至S102：
S101、第一设备为第二设备配置N个工作状态。
其中，N为大于1的整数。
本申请实施例中，第一设备可以为网络设备(例如基站)或终端。
本申请实施例中，第二设备为用于辅助第一设备进行无线通信的设备。其中，第二设备可以为相干转发设备，还可以为非相干转发设备。
示例性地，第二设备可以为智能表面设备或者中继设备或者反向散射设备。
需要说明的是，智能表面设备的转发信号是与其他多径信号相干的，即相对于发射端信源信号具有稳定频率。对于中继设备，其经过放大后的信号的频率或者相位会发生随机的偏移，因此与其他多径信号是非相干叠加。此外，中继设备的应用场景用于覆盖扩展或者覆盖小区边缘，其他多径信号的能量较弱，转发信号切换的分集方式性能增益不明显。但是在热点增强的场景中可以使用中继设备增强热点区域或者用户的性能，因此可以在上述情况下采用中继设备作为第二设备。对于中继设备，在一次数据传输时间段内(一个或者几个连续时隙)，放大器带来的影响近似为连续变化，因此可以实现传输分集。还可以在放大器后接入不同的移相器件实现模拟波束控制和相位控制，从而实现传输分集。
可以理解，在第二设备为智能表面设备的情况下，第二设备的N个工作状态可以为第二设备的中所有智能表面器件的工作状态的组合。
本申请实施例中，第二设备根据第一设备为其配置的N个工作状态以及所述工作状态对应的工作时间，在时隙内进行工作状态切换或者在时隙间进行工作状态切换。可以理解的，其配置的N个工作状态可以配置为周期或者半静态出现的，可以配置为动态指示在某个时间段内的。
本申请实施例中，第二设备根据第一设备为其配置的N个工作状态，在一次数据传输的持续时间内，在N个工作状态之中进行工作状态的切换。
示例性地，在上述一次数据传输的持续时间内，可以包括多个时间单元。第二设备在多个时间单元中的每个时间单元内，均可以在N个工作状态之中进行工作状态的切换。
可以理解，第二设备的工作状态与第二设备的控制信息或控制模式一一对应。
示例性地，在第二设备为智能表面设备的情况下，第二设备的N个工作状态可以对应于第二设备的转发波束的空间能量分布状态。
S102、第一设备与第三设备进行数据传输。
其中，数据传输的时间跨越第二设备的N个工作状态的工作时间。上述工作时间可以是若干个OFDM符号或者若干个时隙。
本申请实施例中，第三设备可以为终端。
其中，第二设备的N个工作状态为：第二设备对第一设备或者第三设备的无线信号转发状态。
可选地，本申请实施例中，N个工作状态中不同的工作状态对应第二设备的不同工作模式。
示例性地，以第二设备为智能表面设备举例，在第二设备的入射信号方向固定的情况下，第二设备的N个工作状态中的不同工作状态可以实现不同转发波束。
换言之，N个工作状态中的不同状态对应第二设备转发的不同转发波束。不同转发波束可以包括以下至少一项：相位不同的转发波束、强度不同的转发波束、方向不同的转发波束、宽度不同的转发波束、增益不同的转发波束、旁瓣能量不同的转发波束。

可选地，本申请实施例中，在第一设备与第三设备进行下行数据传输的情况下，上述S102包括以下的S102a或者S102b：
S102a、第一设备通过将数据的一个冗余版本映射到多个时间段的时频资源上，与第三设备进行数据传输。
S102b、第一设备通过将至少两个冗余版本分别映射到多个时间段时频资源上，与第三设备进行数据传输。
需要说明的是，在第一设备与第三设备进行下行数据传输的情况下，需要考虑第二设备在不同工作状态间的切换时延。例如，需要考虑切换时延所占用的时域资源。示例性地，在符号级别的切换时延上，可以不传输数据，并通知第三设备。
本申请实施例中，需要保证第二设备的每个工作状态的时间段内，至少有一个参考信号(例如DMRS)用于进行信道估计和解调解码。由此，第三设备按照配置的时间段接收下行信号并进行信道估计和解调解码。
在本申请实施例中，第一设备可以为第二设备配置N个工作状态。其中，N为大于1的整数。第一设备与第三设备进行数据传输，并且该数据传输的时间跨越第二设备的N个工作状态的工作时间。其中，第二设备的N个工作状态为：第二设备对第一设备或者第三设备的无线信号转发状态。由此，第二设备可以通过第一设备为其配置的至少两个工作状态，分别对第一设备或者第三设备的无线信号转发状态，以使得第一设备与第三设备之间的信道发生变化，并由此及时有效地对第一设备调度的频率资源遇到的频率选择性深衰落情况进行调整，以保证通讯质量和效率。
此外，本申请实施例可以实现传输分集，在第一设备和第三设备通过第二设备进行通信的场景中，通过在一次上行或者下行传输过程中按照预定的规则切换第二设备的工作状态，可以达到改变第一设备和第三设备之间的信道状态的目的，第一设备或第三设备在配置的频率资源上可以接收不同信道状态下的上行或者下行信号，从而获得传输分集。
可选的，在多用户场景中，不同第三设备对第二设备的要求各不相同，通过对第二设备工作状态切换的开环分集，可以避免频繁进行信道估计，保证通信效率，灵活支持多用户调度传输，并保证多用户通信时，至少有一个第二设备的转发波束为用户提供正向增益。
可选地，本申请实施例中，第一设备可以根据第二设备的情况，为第二设备配置与该第二设备的情况相适应的N个工作状态。
示例性地，上述S101包括以下的S101a至S101b：
S101a、第一设备获取第二设备的设备信息，以及目标信道的信道测量结果。
可以理解，在第二设备接入小区(即第二设备完成同步流程，与第一设备保持时频同步)后，第二设备向第一设备上报第二设备的设备信息。相应地，第一设备获取第二设备上报的上述设备信息。
可选地，本申请实施例中，设备信息包括设备类型，设备类型包括以下至少一项：纯无源单元智能表面、有源单元和无源单元的混合型智能表面、具有无线信号相干转发功能的中继、具有无线信号非相干转发功能的中继。

示例性地，假设第二设备的设备功能包括相位控制功能，并且第二设备的设备控制量化精度为控制无线信号参数由1比特的控制信息进行控制。相应地，可以认为第二设备的控制信息“0”对应于第二设备反射信号的相位与入射信号的相位连续，第二设备的控制信息“1”对应于第二设备反射信号的相位与入射信号的相位相差为180°；或者可以认为控制信息“0”对应的第二设备反射信号相位与控制信息“1”对应的反射信号相位相差为180°。
示例性地，假设第二设备的设备功能包括相位控制功能，并且第二设备的设备控制量化精度为控制无线信号参数由大于1比特的控制信息进行控制。则第一设备可以通过产品规格或者协议定义或者第二设备的主动上报，获取第二设备的设备信息。由此，可以确定各个比特信息对应的转发信号的相位状态。
本申请实施例中，目标信道为第二设备与第一设备或第三设备间的无线信道。
可选地，本申请实施例中，目标信道包括：第二设备与S个第三设备间的S个第一信道。一个第三设备对应一个第一信道。其中，信道测量结果基于S个第一信道的信道测量结果得到。S为大于1的整数。
可以理解，目标信道的信道测量结果可以通过信道测量算法获得。
在一个示例中，在第二设备为智能表面的情况下，可以基于第二设备的模拟波束扫描，获得上述信道测量结果。
在另一个示例中，在第二设备为智能表面的情况下，可以基于第二设备信道稀疏性的信道分解，获得上述信道测量结果。
S101b、第一设备根据设备信息和信道测量结果，为第二设备配置N个工作状态。
本申请实施例中，根据上述设备信息，第一设备可以获得需要为第二设备配置的工作状态的数量；根据上述信道测量结果，第一设备可以获得需要为第二设备配置的工作状态的集合。
如此，第一设备可以根据第二设备的设备信息以及信道测量结果，为第二设备配置与该第二设备的情况相适应的工作状态。以达到通过第二设备进一步提高第一设备和第三设备之间的通信效率和质量的目的。
可选地，本申请实施例中，在上述S101b之前，无线通信方法包括以下的S103或者S104：
S103、第一设备向第三设备发送P个参考信号。

其中，P个参考信号为经过第二设备分别使用P个预定义工作状态进行转发的信号。
本申请实施例中，目标信道包括：P个参考信号对应的信道。
本申请实施例中，P为大于或等于1的整数。
可以理解，为了通过模拟波束扫描进行信道测量，在信道测量阶段，第一设备或第三设备需要多次向对方发送上述参考信号。其中，上述参考信号由第二设备在第一设备和第三设备之间进行转发。
其中，第二设备具有多个预定义工作状态(可以理解为固定工作状态)。
在一个示例中，假设第一设备向第三设备发送P个参考信号。相应地，第二设备在接收到来自第一设备的P个参考信号后，分别使用P个预定义工作状态中的各个工作状态，对P个参考信号向第三设备进行转发。
在另一个示例中，假设第一设备接收第三设备发送的P个参考信号。相应地，第二设备在接收到来自第三设备的P个参考信号后，分别使用P个预定义工作状态中的各个工作状态，对P个参考信号向第一设备进行转发。
如此，第一设备可以根据第二设备转发的P个参考信号，确定第二设备的P个预定义工作状态的通信质量，并据此为第二设备配置与其适应的N个工作状态。
可选地，本申请实施例中，P个参考信号中任意两个参考信号的发送时间间隔大于第二设备所需的工作状态切换时间。
本申请实施例中，考虑到第二设备在N个工作状态中进行工作状态切换的时间，第一设备接收或发送参考信号时需要满足上述预定的时间间隔，即P个参考信号中任意两个参考信号的发送时间间隔大于第二设备所需的工作状态切换时间。

S101b2、第一设备从P个第二设备的预定义工作状态中选择N个工作状态。
本申请实施例中，第一设备可以从P个第二设备的预定义工作状态中选择通信质量相对较佳的几个工作状态，并将几个工作状态作为上述的N个工作状态。

N个工作状态包括：目标预定义工作状态，以及设置第一偏置量后的目标预定义工作状态。
可以理解，设置第一偏置量后的目标预定义工作状态下转发的信号与目标预定义工作状态下转发的信号的空间能量分布不变，但是二者之间的相位发生对应的变化。
示例性地，假设第二设备的设备控制量化精度为控制无线信号参数由1比特控制信息进行控制，假设第二设备具有N个器件单元。则通过波束扫描的方式，可以确定了第二设备转发的最优波束对应的目标预定义工作状态为：Φ opt＝{b 0，b 1…b N-1}。其中，b i代表第i个器件单元的控制信息。相应地，在偏置量为1的情况下，设置第一偏置量后的目标预定义工作状态为：
Figure PCTCN2022094747-appb-000005
如此，第一设备可以在信道测量结果中选择信号质量最好的测量结果对应的第二设备的工作状态，将其作为目标预定义工作状态，并对其进行偏置，获得上述N个工作状态，以使得第一设备为第二设备配置N个工作状态的工作时间长度、周期，以及出现顺序。

可选地，本申请实施例中，上述S101b包括以下的S101b7至S101b9：
S101b7、第一设备根据信道测量结果，确定第二设备的转发信号的M个波束方向。
其中，一个波束方向对应至少一个工作状态。其中，M大于或等于1。
可以理解，由于多径信号的影响，第一设备可以确定第二设备的多个信号方向，并且各个信号方向的能量强度可以不同。
S101b8、第一设备按照波束方向，确定N个工作状态。
S101b9、第一设备为第二设备配置N个工作状态。

其中，N个工作状态包括：第一工作状态，以及设置第二偏置量后的第一工作状态。
换言之，如果第一设备使用单一的信号方向或者信号最强的方向作为第二设备转发信号的波束方向，那么可以使用基于偏置量的方式生成第二设备的候选工作状态。
可选地，本申请实施例中，在波束方向为至少两个波束方向的情况下，N个工作状态包括：至少两个波束方向中的每个波束方向对应的工作状态。
换言之，如果第一设备可以使用多个信号方向分别生成第二设备的候选工作状态。
可选地，本申请实施例中，在多用户场景中，第一设备可以根据各个终端的信道测量结果，将信号方向相近的第三设备分为一组，并为其共用的第二设备配置相同的候选工作状态。
本申请实施例中，第一设备与第三设备之间可以进行上行数据的传输，也可以进行下行数据的传输。其中，图7为本申请实施例提供的一种无线通信方法的下行通信流程示意图。可以理解，上行数据传输和下行数据传输过程中，第一设备为第二设备配置N个工作状态的方式基本相同。
上行数据传输和下行数据传输过程中的区别在于信道测量阶段，第三设备发送上行参考信号，第一设备检测上行参考信号，并进行信道估计确定第二设备的候选工作状态。
可以理解，在多用户场景中，多个第三设备的上行参考信号通过时分、频分或者码分的方式进行复用。
可选地，本申请实施例中，上下行的信道训练和数据传输可以结合配置，即：可以使用下行参考信号进行信道训练，再发送上行数据；或者使用上行参考信号进行信道训练，再发送下行数据。
可选地，本申请实施例中，无线通信方法还包括以下的S105：
S105、在第一设备通过第二设备与第三设备进行无线通信之前，第一设备为第三设备配置一次数据传输的时间资源。
其中，时间资源包括多个时间段，多个时间段分别与N个工作状态的时间段相对应。
本申请实施例中，第一设备需要分别为第二设备和第三设备配置数据传输的参数。
其中，第一设备需要为第二设备配置的数据传输的参数即为上述N个工作状态，以及N个工作状态对应的时间段(即在不同时间段内N个工作状态之间的切换规则)。上述时间段可以是多个符号或者多个时隙或者多个子帧。第二设备根据第一设对其的配置来调整其工作状态。
其中，第一设备需要为第三设备配置的数据传输的参数即为频率资源。并且，第一设备指示第二设备采用工作状态切换的传输分集模式，对数据或信号进行转发。具体而言，在一次数据传输中，第一设备为第三设备配置一次数据传输的时间资源。该时间资源包括的多个时间段分别与第二设备的候选工作状态的时间段相对应。
可选地，本申请实施例中，第一设备为第三设备配置传输资源时，不需要指示本次传输是普通传输还是基于第二设备工作状态切换的传输。
