对于当下的通信技术而言，真实通信场景下的信道模型十分复杂，多径也非常丰富，因而很难准确地确定通信信号的来波方向。其次，对于多径丰富的通信场景，智能反射面要想准确获取信道信息就必须具有与网络设备进行信道交互的功能，从而要求设计独立的信息传输链路，同时智能反射面还必须具有对通信信号进行接收和处理的功能。当前的网络协议架构对此并不支持。最后，引入智能反射面与网络设备之间的信息交互会极大的增加智能反射面的部署成本，使得智能反射面难以大规模部署。同时也会增加电力能源的消耗，也违背了开发智能反射面的初衷。因此，开发未知信道条件下智能反射面的编码方法是十分必要的。
为此，本申请提供了一种智能反射面相移控制方法及相关产品，通过根据通信需求和第一条件样本统计值，确定符合通信需求的第一相移阵列，发送该第一相移阵列，使得根据该第一相移阵列设置智能反射面的相移值，从而可以根据通信需求，灵活地改变接收端的接收信号的质量。
在本申请中，智能反射面不需要与网络设备进行交互，不需要网络设备提供信道详细数据以及估计结果，仅提供检测接收端接收到的信号的质量，基于算法运行得到在当前场景下符合通信需求的信道质量的智能反射面的相移阵列。

其中，信号检测器1032用于检测接收端接收到的信号的质量，得到接收端的第一接收信号质量信息，其中，第一接收信号质量信息用于表征接收端接收到的信号的质量；
信号检测器1032还用于向相移处理器1033输出第一接收信号质量信息；
相移处理器1033用于获取接收端的第一接收信号质量信息；
相移处理器1033还用于根据第一接收信号质量信息及信号对应的相移阵列生成第一条件样本统计值；
相移处理器1033还用于根据通信需求和第一条件样本统计值，确定符合通信需求的第一相移阵列，第一相移阵列包括智能反射面的至少一个反射单元的相移值；
相移处理器1033还用于向相移控制器发送第一相移阵列；
相移控制器1034用于根据第一相移阵列设置智能反射面1031的至少一个反射单元的相移值。
即相移控制器1034用于控制智能反射面的波束赋形编码，信号检测器1032用于测量和收集接收端的通信信号的质量信息，相移处理器1033根据信号检测器端的采样信息以及对应的相移控制器1034端的波束赋形编码确定优化建议，并将优化建议下发给相移控制器1034。
本申请实施例的技术方案可以应用于各种通信系统。例如：第三代(3rd generation，3G)移动通信系统、第四代(4th generation，4G)移动通信系统、第五代(5th generation，5G)移动通信系统，或者其他未来的新型移动通信系统等。该通信系统还可以是同时支持多种无线技术的通信系统，例如同时支持长期演进(long term evolution，LTE)和新无线(new radio，NR)的通信系统；或者，该通信系统还可以是支持近距离通信的通信系统，例如，支持侧行链路(sidelink，SL)技术的通信系统，支持无线保真(wireless fidelity，WiFi)技术的通信系统等等。
其中，本申请实施例中的网络设备101可以是基站(base station)、演进型基站(evolved NodeB，eNodeB)、发送接收点(transmission reception point，TRP)、5G移动通信系统中的下一代基站(next generation NodeB，gNB)、第六代(6th generation，6G)移动通信系统中的下一代基站、未来移动通信系统中的基站或WiFi系统中的接入节点等；也可以是完成基站部分功能的模块或单元，例如，可以是集中式单元(central unit，CU)，也可以是分布式单元(distributed unit，DU)。网络设备101可以是宏基站，也可以是微基站或室内站，还可以是中继节点或施主节点等。本申请的实施例对网络设备101所采用的具体技术和具体设备形态不做限定。为了便于描述，下文以基站作为网络设备的例子进行描述。
其中，本申请实施例中的接收端102是一种用于接收或者发送信号的实体，例如手机等。接收端102也可以称为终端(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。网络设备101和接收端102还可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、平板电脑(Tablet)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请实施例中对接收端102所采用的具体技术和具体设备形态不做限定。
其中，本申请实施例中的智能反射面1031的表面是由大量低成本的被动无源反射单元1035组成的。该智能反射面1031通过适当编码(即设置智能反射面上每个反射单元的相移值，经过第n个反射单元的信道h n相移之后信道变为
Figure PCTCN2022118261-appb-000009
θ n为第n个反射单元设置的相移值，一组波束赋形编码对应一组相移值)能够改变接收端接收信号的质量，扩展网络设备无线信号的覆盖范围。还可以通过适当编码降低或者抵消干扰的信号，从而提升接收端102的通信体验。还可以通过智能反射面的表面增加无线信道多径，降低信道相关性，从而提升无线信道的秩，实现更多流传输，提升了接收端102的通信体验；或者通过智能反射面的表面减少无线信道多径，提高信道相关性，从而降低无线信道的秩，降低特定位置接收端102 的传输速率。对于时分双工(time division duplex，TDD)技术中，通过设置智能反射面中的相移阵列，可以实现上行和下行一起优化，即优化好下行信道质量的同时，也实现对上行信道质量的优化。由于引入智能反射面，在同等信道质量的前提下，网络设备的发射功率可以适当降低，从而实现绿色网络和匹配“碳中和”的要求，以及实现一定的网络节能的功能。
如图1所示，在室外应用场景中，网络设备101将信号发送出来，有的信号直接传输至接收端102中，而有的信号则会经过其他物体的反射再被接收端102接收，例如墙面的反射，还有的信号则会通过智能反射面1031反射之后被接收端102接收。具体的，在实际应用过程中，多块智能反射面可以进行协作，使得信号在传输的过程中更加的稳定。单块的智能反射面还可以分成多个区域，不同的区域承担不同的工作任务，例如优化不同用户的通信体验，针对不同的通信要求进行协作优化等。需要说明的是，本申请实施例中，智能反射面可以是二维的平面结构，也可以是三维的立体结构，如图2所示，为本申请示例的一种智能反射面的结构示意图，该智能反射面的形状可以是折叠的书本形状。需要说明的是，可以在加工时直接加工成具有复杂三维结构的智能反射面，也可以先生产简易的智能反射面，再按照一定角度和结构拼接成具有复杂三维结构的立体智能反射面。当智能反射面是三维的立体结构时，可以显著的增强多输入多输出场景中信道矩阵的秩。
本申请实施例中的方法不仅可以应用在室外场景中，还可以应用在室内场景中。示例性地，在室内应用场景中，可以将智能反射面1031放置于室内的各个转角或者死角，以改变接收端接收信号的质量，减少无线信号的死角，提高无线通信传输的字节数，在多天线通信的场景下还可以显著的增加多径，降低信道相关性，从而提升多输入多输出的信道矩阵的秩，进而提升室内用户的无线通信体验。
本申请实施例中的方法也可用于减弱接收信号的质量的场景。例如，可以通过编码使得信号相干抵消，故意制造信号死角，以增强通信的安全性等。
基于上述图1所示的通信系统架构，下面将对本申请实施例中的智能反射面相移控制方法进行详细描述。本申请实施例中的智能反射面相移控制方法可以应用于不同的场景，且每个场景的对应的实施步骤略有不同，下面将分别进行描述。
一、对于单输入单输出(single-input single-output，SISO)系统下的单用户场景。
请参阅图3，为本申请实施例提供的一种智能反射面相移控制方法的流程示意图，该方法可以包括以下步骤：
S301.相移处理器获取接收端的第一接收信号质量信息，其中，该第一接收信号质量信息用于表征接收端接收到的信号的质量。
网络设备发送无线信号，有的无线信号直接到达接收端处；有的无线信号则会通过智能反射面的反射到达接收端处；还有的无线信号可能会通过其他物体的反射到达接收端处。
其中，对于智能反射面反射无线信号，其具体实现可以是：
相移处理器在线生成多个相移阵列，每个相移阵列中的每一项给出对应智能反射面的一个反射单元的相移值。例如，假设相移处理器生成T个相移阵列，该智能反射面包括N个反射单元。对于第t个相移阵列，生成的相移阵列可以表示为如下公式1：
Figure PCTCN2022118261-appb-000010
其中，
Figure PCTCN2022118261-appb-000011
表示第t个相移阵列中第n个反射单元设置的相移状态。
相移处理器把生成的多个相移阵列发送给相移控制器。可以理解的是，相移处理器可以一次性发送所有的相移阵列，也可以逐次进行发送，具体此处不做限定。
相移控制器把相移阵列下发给智能反射面。每当相移控制器下发一个相移阵列，接收端 会相应地接收到第一接收信号。因此，当智能反射面采用多个相移阵列，接收端会接收到多个第一接收信号。
信号检测器则会对第一接收信号进行测量，得到第一接收信号质量信息。该第一接收信号质量信息用于表征接收端接收到的信号的质量。具体地，第一接收信号质量信息可以表征接收端接收到的一个或多个第一接收信号的质量的均值或者加权值，也可以表征接收端接收到的其中一个第一接收信号的质量。其中，第一接收信号质量信息可以包括以下至少一项：参考信号接收功率RSRP、信干噪比SINR、频谱效率、传输速率、多个接收端的传输速率之和、误码率、时延。
信号检测器输出获得的第一接收信号质量信息给相移处理器。相应地，相移处理器获取该第一接收信号质量信息。
示例性地，在测量第一接收信号期间，相移控制器的时钟与相移处理器的时钟保持同步。
在整个测量第一接收信号的过程中，智能反射面不需要和网络设备进行任何信息的交互，接收端也不需要进行任何信道估计工作。
S302.相移处理器根据第一接收信号质量信息及信号对应的相移阵列生成第一条件样本统计值。
相移处理器在获取到第一接收信号质量信息之后，根据第一接收信号质量信息和接收端接收到的信号对应的相移阵列，生成第一条件样本统计值。
其中，相移处理器获取接收端接收到的信号对应的相移阵列的方法有多种：
在一种实现中，相移处理器和相移控制器中都预置有相移阵列码本，其中相移阵列码本包含了多个相移阵列。在保持时钟同步的前提下，相移控制器依次从相移阵列码本中选取相移阵列并下发给智能反射面，而相移处理器同步依次从相移阵列码本中读取相移阵列用于和第一接收信号质量信息配对。
在另一种实现中，相移处理器和相移控制器不需要预置相移阵列码本，相移处理器在线生成多个相移阵列，然后发送给相移控制器。或者，还可以是相移控制器生成多个相移阵列，发送给相移处理器。
相移处理器具体获取多个相移阵列的方法此处不做限定。
假设智能反射面包括N个独立的反射单元，每个反射单元的相移值来自于离散集合，该离散集合可以通过以下公式2表示：
Figure PCTCN2022118261-appb-000012
其中，K为可供每个反射单元选择的相移值的数量。
其中，第一条件样本统计值表示当某个反射单元的相移值固定后，而其它反射单元的相移值随机选取时，根据随机样本所估计的第一接收信号质量的平均值。根据第一接收信号质量信息以及对应的波束赋形编码(即信号对应的相移阵列)，计算得到第n个反射单元的相移值θ n为φ k时的第一条件样本统计值为如下公式3所示：
Figure PCTCN2022118261-appb-000013
其中，y t表示第t个测量样本数据(即第一接收信号质量信息)，θ t表示第t个测量样本数据对应的相移阵列，
Figure PCTCN2022118261-appb-000014
是满足θ n＝φ k的测量样本子集。对应N个反射单元，每个反射单元能够取K个相移值，因而，最终能够获得NK个第一条件样本统计值。
下面给出计算第一条件样本统计值的示例：
考虑N＝3，K＝2，T＝6的情况，即智能反射面有3个反射单元，每个反射单元有2种可以 选择的相移值：0和π，测量样本集有6组样本。所得测试样本集与样本数据集示例如下表1所示：
表1
Figure PCTCN2022118261-appb-000015
根据上述公式3计算得到
Figure PCTCN2022118261-appb-000016
其中，满足θ 1＝0的样本有样本1，样本3以及样本6，即
Figure PCTCN2022118261-appb-000017
这样计算得到：
Figure PCTCN2022118261-appb-000018
以此类推，可以计算得到3个反射单元的第一条件样本统计值如下表2所示：
表2
Figure PCTCN2022118261-appb-000019
另外，考虑多块智能反射面协作的场景，定义L块智能反射面的反射单元总数为
Figure PCTCN2022118261-appb-000020
其中N l表示第l块智能反射面上的反射单元的数量。
所有L个反射面共同采样，共享一个数据集，即根据样本数据集{y 1,…,y t,…,y T}以及对应的相移阵列{θ 1,…,θ t,…,θ T}，计算得到NK个第一条件样本统计值J n,k。其中，T为测量样本集的大小，
Figure PCTCN2022118261-appb-000021
为L个向量
Figure PCTCN2022118261-appb-000022
拼接而成的N维向量，每个分向量分别独立对应了一个智能反射面的各个反射单元的相移值。这里θ t可以简写为：
Figure PCTCN2022118261-appb-000023
S303.相移处理器根据通信需求和第一条件样本统计值，确定符合通信需求的第一相移阵列，该第一相移阵列包括智能反射面的至少一个反射单元的相移值。
相移处理器可以根据具体的通信需求，以及根据第一条件样本统计值，确定符合通信需求的第一相移阵列。
其中，通信需求可以包括增强接收端的信号质量和减弱接收端的信号质量。因此，根据通信需求的不同，步骤S303的具体实现可以不同：
(一)通信需求为增强接收端的信号质量
增强接收端的信号质量的场景例如可以是：将智能反射面放置于室内的多个转角或者死角，以减少无线信号的死角，提高无线通信传输的字节数，从而增强接收端的信号质量。在多天线通信的场景下还可以显著的增加多径，降低信道相关性，从而提升多输入多输出的信道矩阵的秩，进而提升室内用户的无线通信体验。
其中，确定满足增强接收端的信号质量的通信需求的第一相移阵列的实现可以包括但不限于如下实现A1和A2：
在一种实现A1中，步骤S303可以包括：获取每个反射单元对应的第一条件样本统计值 中的最大值对应的相移值，将得到的多个相移值组成第一相移阵列。
即对于第n个反射单元，选择K个第一条件样本统计值中的最大值对应的相移值作为解，即：
Figure PCTCN2022118261-appb-000024
这里的
Figure PCTCN2022118261-appb-000025
为第n个反射单元最终的相移值，最终确定的编码记为θ CSM。
以此类推，获得N个反射单元中每个反射单元对应的第一条件样本统计值中的最大值对应的相移值，将得到的多个相移值组成第一相移阵列。
在另一种实现A2中，步骤S303可以包括：根据至少两个第一候选相移阵列，确定第一相移阵列。
具体地，根据至少两个第一候选相移阵列，确定第一相移阵列，包括以下步骤：
A21.确定至少两个第一候选相移阵列；
A22.获取多个第二接收信号质量信息，其中，多个第二接收信号质量信息用于表征接收端基于每个第一候选相移阵列接收到的信号的质量；
A23.根据多个第二接收信号质量信息及每个第一候选相移阵列，生成第二条件样本统计值；
A24.获取第二条件样本统计值中的最大值对应的第一候选相移阵列，作为第一相移阵列。
即对于每个反射单元，首先确定至少两个第一候选相移阵列，记为
Figure PCTCN2022118261-appb-000026
相移控制器将至少两个第一候选相移阵列发送给智能反射面。智能反射面基于每个第一候选相移阵列反射发送端发送的信号。信号检测器检测接收端接收到的信号，获得第二接收信号质量信息并发送给相移处理器，该第二接收信号质量信息用于表征接收端基于该第一候选相移阵列接收到的信号的质量。相移处理器根据多个第二接收信号质量信息及每个第一候选相移阵列，生成第二条件样本统计值，具体实现可参考步骤S302。最后，相移处理器获取第二条件样本统计值中的最大值对应的第一候选相移阵列，作为第一相移阵列，记为θ ECSM，即
Figure PCTCN2022118261-appb-000027
以下给出一种如何根据多个第一候选阵列，确定第一相移阵列的原理。
对于第n个反射单元，用第一条件样本统计值求解：如图4所示，为本申请实施例示例的一种确定第一相移阵列的示意图。这里定义四个以
Figure PCTCN2022118261-appb-000028
为圆心角的扇形S 1,S 2,S 3和S 4。把直接信道h 0看成二维平面里以原点为起点的向量。不失一般性，假设h 0位于x轴方向上，则S 1为角度
Figure PCTCN2022118261-appb-000029
到
Figure PCTCN2022118261-appb-000030
的扇形区域，S 2为角度0到
Figure PCTCN2022118261-appb-000031
的扇形区域，S 3为角度0到
Figure PCTCN2022118261-appb-000032
的扇形区域，S 4为角度
Figure PCTCN2022118261-appb-000033
到
Figure PCTCN2022118261-appb-000034
的扇形区域。
对于每一个反射单元选择K个第一条件样本统计值中的最大值对应的相移值作为优化解(case1)，相当于将所有反射信道转移到S 2,S 3两个扇形区域内。然而，这样可能并非是最优解。另外两组候选解是将所有反射信道移到case2:S 1,S 2两个扇形区域，以及将所有反射信道移到case3:S 3,S 4两个扇形区域。
则确定第一候选相移阵列的方法如下：比较
Figure PCTCN2022118261-appb-000035
和
Figure PCTCN2022118261-appb-000036
如果
Figure PCTCN2022118261-appb-000037
则说明信道
Figure PCTCN2022118261-appb-000038
位于S 2扇形内， 则对应case2的相移值为

对应于case3的相移值为

Figure PCTCN2022118261-appb-000043
对应于case3的相移值为
Figure PCTCN2022118261-appb-000044
然后，相移控制器将case1、case2和case3对应的第一候选相移阵列发送给智能反射面。智能反射面基于每个第一候选相移阵列反射发送端发送的信号。信号检测器检测接收端接收到的信号，获得第二接收信号质量信息并发送给相移处理器。相移处理器根据多个第二接收信号质量信息及每个第一候选相移阵列，生成第二条件样本统计值。最后，相移处理器获取第二条件样本统计值中的最大值对应的第一候选相移阵列，作为第一相移阵列，得到最优解。
(二)通信需求为减弱接收端的信号质量
通信需求为减弱接收端的信号质量的场景，例如可以是对抗恶意干扰(anti-jamming)的通信场景。例如，在接收端(Bob)接收来自发送端(Alice)的信号时，容易收到来自恶意方(Eve)的干扰，此时利用智能反射面基于本实施例提出的算法，可以在不需要获取恶意方(Eve)和接收端(Bob)之间信道的条件下屏蔽恶意方(Eve)对接收端(Bob)的干扰。除此之外，也可以用于降低邻近小区基站对于用户主服小区的通信的干扰，不再是简单的制造通信死角。
在减弱信号的算法中，目标是将所有反射信道h n转移到与h 0相反的方向上，当
Figure PCTCN2022118261-appb-000045
小于h 0时这样是合理的；当
Figure PCTCN2022118261-appb-000046
大于h 0时，就需要将一部分反射信道h n转移到h 0同方向上，一部分反射信道转移到h 0相反的方向上。下面分情况进行说明：
1、当
Figure PCTCN2022118261-appb-000047
小于h 0时，可以有以下两种实现方式(A3和A4)确定第一相移阵列：
在一种实现A3中，步骤S303可以包括：获取每个反射单元对应的第一条件样本统计值中的最小值对应的相移值，将得到的多个相移值组成第一相移阵列。
即对于每个反射单元，选择K个第一条件样本统计值中的最小值对应的相移值作为解，即：
Figure PCTCN2022118261-appb-000048
这里的
Figure PCTCN2022118261-appb-000049
为第n个反射单元最终的相移值，最终确定的编码记为θ CSM。
以此类推，获得N个反射单元中每个反射单元对应的第一条件样本统计值中的最小值对应的相移值，将得到的多个相移值组成第一相移阵列。
在另一种实现A4中，步骤S303可以包括：根据至少两个第二候选相移阵列，确定第一相移阵列。
具体地，根据至少两个第二候选相移阵列，确定第一相移阵列，包括以下步骤：
A41.确定至少两个第二候选相移阵列；
A42.获取多个第三接收信号质量信息，其中，多个第三接收信号质量信息用于表征接收端基于每个第二候选相移阵列接收到的信号的质量；
A43.根据多个第三接收信号质量信息及每个第二候选相移阵列，生成第三条件样本统计值；
A44.获取第三条件样本统计值中的最小值对应的第二候选相移阵列，作为第一相移阵列。
即对于每个反射单元，首先确定至少两个第二候选相移阵列，记为
Figure PCTCN2022118261-appb-000050
相移控制器将至 少两个第二候选相移阵列发送给智能反射面。智能反射面基于每个第二候选相移阵列反射发送端发送的信号。信号检测器检测接收端接收到的信号，获得第二接收信号质量信息并发送给相移处理器，该第二接收信号质量信息用于表征接收端基于该第二候选相移阵列接收到的信号的质量。相移处理器根据多个第二接收信号质量信息及每个第二候选相移阵列，生成第三条件样本统计值，具体实现可参考步骤S302。最后，相移处理器获取第三条件样本统计值中的最小值对应的第二候选相移阵列，作为第一相移阵列，记为θ ECSM，即
Figure PCTCN2022118261-appb-000051
在至少两个第二候选相移阵列中选择第一相移阵列的方法与上述增强接收端信号质量时选择第一相移阵列的方法类似，所不同的是，要把所有的反射信道移相到与h 0相反的扇形区间。
如图5所示的本申请实施例示例的又一种确定第一相移阵列的示意图，则确定第一候选相移阵列的方法如下：比较

对应于case3的相移值为
Figure PCTCN2022118261-appb-000061
然后，相移控制器将case1、case2和case3对应的第一候选相移阵列发送给智能反射面。智能反射面基于每个第二候选相移阵列反射发送端发送的信号。信号检测器检测接收端接收到的信号，获得第二接收信号质量信息并发送给相移处理器。相移处理器根据多个第二接收信号质量信息及每个第二候选相移阵列，生成第三条件样本统计值。最后，相移处理器获取第三条件样本统计值中的最小值对应的第二候选相移阵列，作为第一相移阵列，得到最优解。
2、当
Figure PCTCN2022118261-appb-000062
大于h 0时，算法如下：
此时需要将一定比例的反射单元移相到与h 0同相，剩余比例的反射单元移相到与h 0相反的方向上。
在又一种实现A5中，智能反射面包括N个反射单元，第一相移阵列包括第一相移子阵列和第二相移子阵列，第一相移子阵列包括智能反射面的

进一步地，智能反射面控制系统可以预存多种相移控制方案或相移阵列模式，每种方案对应一种应用需求，例如对不同区域提高(或缩小)覆盖面，降低干扰，提升速率。用户可以根据需求通过无线控制信令选择智能反射面的相移控制方案或相移阵列模式。具体地，该方法还可以包括：
相移处理器接收相移阵列模式集合。该相移阵列模式集合包括上述A1～A5中的至少一种相移阵列模式。
相移处理器存储至少一个相移阵列模式标识与至少一个相移阵列模式的对应关系。
相移处理器接收用户的选择指令，该选择指令包括第一相移阵列模式的标识。
相移处理器根据第一相移阵列模式的标识和对应关系，选择对应的相移阵列模式。
S304.相移处理器发送第一相移阵列。相应地，相移控制器接收该第一相移阵列。
在确定了第一相移阵列后，相移处理器向相移控制器发送第一相移阵列。
可以理解的是，在实际应用过程中，相移处理器可以在确定了部分反射单元的相移值之后，就将包括了该部分反射单元的相移值的第一相移阵列发送给相移控制器；也可以是在确定了全部反射单元的相移值之后，将包括了全部反射单元的相移值的第一相移阵列发送给相移控制器，具体此处不做限定。
S305.相移控制器根据第一相移阵列设置智能反射面的至少一个反射单元的相移值。
其中，相移控制器用于控制智能反射面的波束赋形编码。相移控制器从相移处理器接收到第一相移阵列后，根据第一相移阵列设置智能反射面的至少一个反射单元的相移值。
示例性地，相移控制器在接收到第一相移阵列之后，根据该第一相移阵列设置智能反射面的各个反射单元的相移值。
示例性地，若相移控制器接收到的第一相移阵列包括部分反射单元的优化的相移值，则根据第一相移阵列设置该智能反射面的部分反射单元的相移值。
根据本申请实施例提供的一种智能反射面相移控制方法，通过根据通信需求和第一条件样本统计值，确定符合通信需求的第一相移阵列，发送该第一相移阵列，使得根据该第一相移阵列设置智能反射面的相移值，从而可以根据通信需求，灵活地改变接收端的接收信号的质量。
在本实施例中，该方法采用一种基于样本分析的优化思路，智能反射面不需要和网络设备进行任何信息交互，接收端也不需要进行任何信道估计工作。解决了智能反射面优化问题中过度依赖完全已知信道信息的问题。利用统计方法将高维的离散非凸优化问题(即波束赋 形编码)在线性时间复杂度下进行求解，在采样次数有限的情况下，依然可以获得近优解。
可以理解的是，在实际应用过程中，相移处理器可以在确定智能反射面的部分反射单元的相移值后，将包括该部分反射单元的相移值的第一相移阵列发送给相移控制器；相移处理器可以在确定智能反射面的全部反射单元的相移值后，将包括全部反射单元的相移值的第一相移阵列发送给相移控制器。
请参阅图6，为本申请实施例提供的又一种智能反射面相移控制方法的流程示意图。该智能反射面包括N个反射单元，N为正整数。该方法可以包括以下步骤：
S601.相移处理器获取接收端的第一接收信号质量信息，其中，该第一接收信号质量信息用于表征接收端接收到的信号的质量。
S602.相移处理器根据第一接收信号质量信息及信号对应的相移阵列生成第一条件样本统计值。
S603.相移处理器根据通信需求和第一条件样本统计值，确定符合通信需求的第一相移阵列。
在本实施例中，该第一相移阵列包括智能反射面的Y 1个反射单元的相移值，其中，1≤Y 1≤N，Y 1为正整数。
S604.相移处理器发送第一相移阵列。相应地，相移控制器接收该第一相移阵列。
与图3所示实施例不同的是，本实施例中，第一相移阵列包括智能反射面中部分反射单元的优化的相移值。
S605.相移控制器根据第一相移阵列设置智能反射面的至少一个反射单元的相移值。
由于本实施例中第一相移阵列包括智能反射面中部分反射单元的优化的相移值，因此，相移控制器针对剩余还没有确定优化的相移值的反射单元生成对应的随机样本，并将这些随机样本下发至智能反射面，让智能反射面将剩余的反射单元的相移值设置为这些随机样本。
该方法还可以包括以下至少一轮确定剩余的智能反射面的反射单元的相移值的流程，直至确定符合通信需求的智能反射面的N个反射单元的相移值。其中，每一轮确定剩余的智能反射面的反射单元的相移值的流程包括以下步骤S606～S608：
S606.相移处理器获取接收端的第四接收信号质量信息，其中，第四接收信号质量信息是当智能反射面的Y 1个反射单元确定了相移值、N-Y 1个反射单元还未确定相移值时，接收端接收到的信号的质量。
该步骤的具体实现可参考步骤S301。
S607.相移处理器根据第四接收信号质量信息及信号对应的相移阵列生成第四条件样本统计值。
该步骤的具体实现可参考步骤S302。
S608.相移处理器根据通信需求和第四条件样本统计值，确定符合通信需求的第二相移阵列，第二相移阵列包括智能反射面的Y 2个反射单元的相移值，其中，1≤Y 2≤N-Y 1，Y 2为正整数。
该步骤的具体实现可参考步骤S303。
对于上述步骤S606～S608，具体地，对于通信需求为增强接收信号的质量的场景，对于第m次迭代，利用采集得到的数据(T m个N m维样本)，计算所有反射单元对应不同相移变化下的第一条件样本统计值J m：对于单个反射单元n，选择所有K个可选相移值中，第一条件样本统计值中最大的一个，作为当前反射单元的临时解

结束本轮交互。
对于通信需求为减弱接收信号的质量的场景，数据采集过程中，将一部分数据传至相移处理器，相移处理器输出初始相移优化建议后下发至智能反射面的相移控制模块，由相移控制模块指导智能反射面相移变化方式，同时继续采集数据，实现边学习边优化。
这一部分的算法核心依然是第一条件样本统计值，不同的是具体的求解步骤，期望最终实现到一部分反射信道信号用于减弱抵消直接信道信号强度，一部分反射信道信号用于相互减弱抵消，从而达到整体减弱接收端的信号质量的效果。
整个算法由参数估计以及M次测量模块与相移处理器的数据交互组成，参数估计步骤如下：
计算信道质量的期望与第一条件样本统计值理论值的差；
计算信道质量的期望与第一条件样本统计值估计值的差；
通过最小化期望与第一条件样本统计值理论值和期望与第一条件样本统计值估计值的差，得到直接信道的质量和反射信道的质量比值ρ的估计。至此完成参数估计部分。
第m次交互具体算法步骤如下：
步骤(a)，利用采集得到的数据(T m个N m维样本)，计算所有反射单元对应不同相移变化下的第一条件样本统计值J m：对于单个反射单元n，选择所有K个可选相移状态中，第一条件样本统计值中最弱的一个，作为当前反射单元的临时解

Figure PCTCN2022118261-appb-000086
步骤(d)，结束本轮交互。
示例性地，在实际应用过程中，对于剩余的未确定优化的相移值的反射单元，可以每次只确定部分反射单元的优化的相移值，即需要多次循环执行步骤S606～S608，直到确定智能反射面中所有反射单元的相移值。还可以是只执行一次步骤S606～S608，就确定智能反射面中剩余所有反射单元的相移值。具体根据实际需要进行确定，本申请不作限定。
根据本申请实施例提供的一种智能反射面相移控制方法，通过根据通信需求和第一条件样本统计值，确定符合通信需求的第一相移阵列，发送该第一相移阵列，使得根据该第一相移阵列设置智能反射面的相移值，从而可以根据通信需求，灵活地改变接收端的接收信号的质量。

其中，采样对象y t可以为接收端的频谱效率、速率等表征多天线通信质量的物理量。
三、SISO系统下的多用户场景

在多用户场景下，可以有多个接收端，对应多个接收信号的质量信息。在多用户的场景下，可能需要对所有接收端中接收到的信号质量最差或者较差的接收端进行通信信号增强的优化。在以增强通信信号为目标的优化场景下，从多个接收端的接收信号中选取的第一接收信号满足：
Figure PCTCN2022118261-appb-000087
其中t代表第t次测量，U代表接收端的数量。
即若需要增强多个接收端的通信质量，可以从多个接收端接收到的接收信号中选出质量最差(或者较差)的作为第一接收信号质量。
对于增强接收信号的质量的场景，增强接收端的信号的质量相当于求解最大值的问题，即要尽量提高多个接收端中通信体验最差的用户的通信体验。对于第t组波束赋形编码对应的U个用户的测量值，定义y t满足：
Figure PCTCN2022118261-appb-000088
即第t次采样结果y t为U个接收端接收到的信号的最小值。
然后执行类似于SISO单用户增强接收端的信号的质量的操作。
对于减弱接收信号的质量的场景，减弱接收端信号相当于求解最小值的问题，即要尽量减弱多个接收端中通信信号最强的通信信号。对于第t组波束赋形编码对应的U个用户的测量值，定义y t满足：
Figure PCTCN2022118261-appb-000089
即第t次采样结果y t为U个接收端接收到的信号的最小值。
然后执行类似于SISO单用户减弱接收端的信号的质量的操作。
四、MIMO系统下的多用户场景
在该场景下，与上述实施例不同的是，相移处理器获取多个接收端的第一接收信号质量信息，该第一接收信号质量信息用来表征接收端的接收到的信号的质量。该第一接收信号质量信息为多维信号质量信息。多维信号质量信息表征了多天线场景下接收端的通信质量。
