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描述，显然，所描述的实施例仅仅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做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。

请参阅图1，为本申请实施例提供的通信***的一个架构图。
该通信***包括发送端101、接收端102以及智能反射面103。需要说明的是，图1所示的发送端101、接收端102以及智能反射面103分别对应的数量和形态仅用于举例，并不构成对本申请实施例的限定，例如，在实际应用过程中，还可以是一个接收端102对应多个智能反射面103。
本申请实施例的技术方案可以应用于各种通信***。例如：第三代(3th generation，3G)移动通信***、***(4th generation，4G)移动通信***、第五代(5th generation，5G)移动通信***、5G NR***，或者其他未来的新型移动通信***等。该通信***还可以是同时支持多种无线技术的通信***，例如同时支持LTE和NR的通信***；或者，该通信***还可以是支持近距离通信的通信***，例如，支持侧行链路(sidelink，SL)技术的通信***，支持无线保真(wireless fidelity，WiFi)技术的通信***等等。
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。发送端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(Pad)、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，智能反射面103的表面是一种由大量低成本的被动无源发射元件组成的平面。该智能反射面103通过适当编码能够提升接收端接收信号的质量。还可以通过适当编码从而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。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。
如图1所示，在室外应用场景中，发送端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103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，具体此处不做限定。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。如图2所示，图2为本申请实施例提供的另一通信***架构图。在图2所示的智能反射面相移控制通信***中，包括了网络设备201、智能反射面203以及接收端202。其中，网络设备201、智能反射面203以及接收端202分别对应的数量和形态仅用于举例，并不构成对本申请实施例的限定，例如，在实际应用过程中，还可以是多个智能反射面203对应一个网络设备201，具体此处不做限定。

基于上述图1和图2的通信***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。
在图3、图4、图5以及图6的描述中，以发送端为基站进行描述，在实际应用过程中，发送端还可以是其他具有发送射频信号功能的设备，例如无线路由器等，具体此处不做限定。
一、对于单输入单输出***下的单用户场景。
请参阅图3，为本申请实施例提供的智能反射面相移控制方法一个流程示意图。
在步骤301中，相移处理器获取多个第一接收信号质量信息。
相移处理器获取多个第一接收信号质量信息，该第一接收信号质量信息表示接收端接收到的第一接收信号的质量。
具体的，基站发送射频信号，有的射频信号直接到达接收端处，有的射频信号则会通过 智能反射面的反射，到达接收端处，还有的射频信号可能会通过其他物体的反射到达接收端处，接收端在接收到这些混合在一起的第一接收信号之后，就会将第一接收信号发送给信号检测器，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。
在一种可能的实现方式中，相移处理器会在线生成多个相移阵列，相移阵列中的每一项给出对应反射单元的相移值。例如对于第t个相移阵列，生成的相移阵列可以表示
Figure PCTCN2022118379-appb-000001
其中，
Figure PCTCN2022118379-appb-000002
表示第t个相移阵列中第n个反射单元设置的相移状态，T为生成的随机相移阵列的数量。
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，智能反射面可以一次性发送所有的相移阵列，也可以一一分别进行发送，具体此处不做限定。
相移控制器依次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，当智能反射面依次采用多个相移阵列，接收端会接收到多个第一接收信号。
信号检测器对多个第一接收信号依次测量它们的第一接收信号质量信息。需要说明的是，第一接收信号质量信息可以是第一接收信号的信号强度，还可以是第一接收信号的信干噪比，可以理解的是，第一接收信号质量信息还可以表示为参考信号接收功率值(reference signal receiving power，RSRP)，还可以是其他用来判定信号质量的参数，例如频谱效率，具体此处不做限定。
在一种可能的实现方式中，在测量第一接收信号的期间，相移控制器的时钟与相移处理器的时钟保持同步，且在整个测量第一接收信号的过程中，智能反射面不需要和基站进行任何信息交互，接收端也不需要进行任何信道估计工作。
在步骤302中，相移处理器根据多个第一接收信号质量信息和多个第一接收信号质量信息对应的相移阵列进行计算，得到多个第一条件样本统计值。
相移处理器在获取到多个第一接收信号质量信息之后，相移处理器根据多个第一接收信号质量信息和多个第一接收信号质量信息对应的相移阵列进行计算，得到多个第一条件样本统计值。
获取第一接收信号质量信息对应的相移阵列有多种方法，在一种可能的实现方式中，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。
在一种可能的实现方式中，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第一接收信号质量信息对应的相移阵列，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第一接收信号质量信息对应的相移阵列，发送给相移处理器。具体相移处理器获取多个第一接收信号质量信息对应的相移阵列的方法此处不做限定。
在一种可能的实现方式中，对于N个独立的反射单元组成的智能反射面来说，每个反射单元的相移状态θ n来自于离散集合，该离散集合可以通过以下等式表示：
Figure PCTCN2022118379-appb-000003
其中，K为可供每个反射单元选择的相移值的数量。
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。
Figure PCTCN2022118379-appb-000004
这里
Figure PCTCN2022118379-appb-000005
表示所有采样中满足条件
Figure PCTCN2022118379-appb-000006
的采样形成的集合。
其中，y(θ)表示接收端接收到的第一接收信号的第一接收信号质量信息，即可以通过对第一接收信号进行测量得到，J k,k表示第n个反射单元的第一条件样本统计值。
以此类推，相移处理器在获取多个第一接收信号质量信息后，可以根据多个第一接收信号质量信息和对应的多个第一接收信号质量信息对应的相移阵列进行计算，得到多个第一条件样本统计值。
可以理解的是，当智能反射面中有N个反射单元时，且相移处理器生成了K个样本，那么相移处理器就会计算得到NK个第一条件样本统计值。
在步骤303中，相移处理器从多个第一条件样本统计值确定最佳相移阵列。
相移处理器在获取到多个第一条件样本统计值后，相移处理器根据多个第一条件样本统计值确定最佳相移阵列。
具体的，在一种可能的实现方式中，当需要提升第一接收信号的信号质量时，将多个第一条件样本统计值中的最大值对应的相移阵列作为最佳相移阵列。例如相移处理器可以通过如下公式对第n个反射单元的相移值进行计算：
Figure PCTCN2022118379-appb-000007
Figure PCTCN2022118379-appb-000008
若需要减弱接收端的信号，在一种可能的实现方式中，将多个第一条件样本统计值中的最小值对应的相移阵列作为最佳相移阵列。例如，可以通过如下公式进行计算：
Figure PCTCN2022118379-appb-000009
Figure PCTCN2022118379-appb-000010
或者在一种可能的实现方式中需要确定减弱信号需要用到的反射单元形成的集合
Figure PCTCN2022118379-appb-000011
不属于集合
Figure PCTCN2022118379-appb-000012
的反射单元在该场景下处于关闭状态。
对于集合
Figure PCTCN2022118379-appb-000013
中的反射单元选取对应的相移值满足：
Figure PCTCN2022118379-appb-000014
Figure PCTCN2022118379-appb-000015
通过上述方式可以确定最佳相移阵列。
在步骤304中，相移处理器向相移控制器发送最佳相移阵列。
在确定了最佳相移阵列之后，相移处理器向相移控制器发送最佳相移阵列。
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一个反射单元的最佳相移之后，就将该包括了一个最佳相移的最佳相移阵列发送给相移控制器，也可以确定了多个甚至所有反射单元的最佳相移阵列之后，再发送给相移控制器，具体此处不做限定。
在步骤305中，相移控制器根据最佳相移阵列设置第一反射单元的相移值。
相移控制器在接收到最佳相移阵列之后，相移控制器需要根据该最佳相移阵列设置智能反射面的各个反射单元的相移值，该智能反射面包括一个或多个第一反射单元，即相移控制器根据最佳相移阵列设置第一反射单元的相移值。
具体的，相移控制器在接收到最佳相移阵列之后，相移控制器向智能反射面发送该最佳相移阵列，指示智能反射面将当前的第一反射单元的相移值设置为最佳相移阵列。在实际应 用过程中，若只获得了部分第一反射单元的最佳相移阵列，则只设置部分第一反射单元对应的部分最佳相移阵列。
在步骤306中，相移处理器获取第二接收信号质量信息。
若在步骤303中，只确定了智能反射面中部分反射单元的最佳相移阵列，则相移控制器会针对剩余还没有确定最佳相移阵列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，让智能反射面将还没确定最佳相移阵列的第二反射单元的相移值对应的设置为这些随机样本，第二反射单元和第一反射单元不同。
具体的，相移控制器生成随机样本以及相移处理器获取第二接收信号质量信息的方法和步骤301中生成随机样本以及相移处理器获取第一接收信号质量信息的方法类似，具体此处不再赘述。
在步骤307中，处理器根据第二接收信号质量信息和第二接收信号质量信息对应的相移阵列生成第二条件样本统计值。
相移处理器在获得了第二接收信号质量信息之后，相移处理器根据第二接收信号质量信息和第二接收信号质量信息对应的相移阵列生成第二条件样本统计值。
具体的，相移处理器根据第二接收信号质量信息生成第二条件样本统计值的方法和步骤302中生成第一条件样本统计值的方法类似，具体此处不再赘述。
在步骤308中，相移处理器从多个第二条件样本统计值确定第二相移阵列。
具体的，确定第二相移阵列的方法和步骤303确定最佳相移阵列的方法类似，具体此处不再赘述。
在步骤309中，相移处理器向相移控制器发送第二相移阵列。
在确定了第二相移阵列之后，相移处理器向相移控制器发送第二相移阵列。
具体的，发送第二相移阵列的方法和步骤304中发送最佳相移阵列的方法类似，具体此处不再赘述。
相移控制器在接收到第二相移阵列之后，相移控制器根据第二相移阵列设置对应的反射单元的相移值。
需要说明的是，在实际应用过程中，可以每次只确定部分反射单元的最优相移阵列，即需要多次循环执行步骤306至309，以确定所有智能反射面中反射单元的最优相移阵列。还可以是只执行一次步骤306至309，就确定智能反射面中剩余所有反射单元的最优相移阵列，具体根据实际需要进行确定，此处不做限定。
如果需要多次循环执行步骤306至309，相移控制器设置反射单元的相移值的具体方式为：相移控制器在循环中接收到相移处理器发送的多个相移阵列，并根据这些相移阵列更新反射单元的相移值。
可以理解的是，步骤306至309，为可选步骤，若在步骤303中，确定了所有智能反射面的反射单元的最佳相移阵列之后，则不需要执行步骤306至309。

在步骤607中，相移处理器获取第二接收信号质量信息。
在步骤608中，处理器根据第二接收信号质量信息和第二接收信号质量信息对应的相移阵列生成第二条件样本统计值。
在步骤609中，相移处理器从多个第二条件样本统计值确定第二相移阵列。
在步骤610中，相移处理器向相移控制器发送第二相移阵列。
本实施例中，步骤602至步骤610所执行的方法和图5所示实施例中步骤502至步骤510所执行的方法类似，具体此处不再赘述。
需要说明的是，在实际应用过程中，可以每次只确定部分反射单元的最优相移阵列，即需要多次循环执行步骤607至610，以确定所有智能反射面中反射单元的最优相移阵列。还可以是只执行一次步骤607至610，就确定智能反射面中剩余所有反射单元的最优相移阵列，具体根据实际需要进行确定，此处不做限定。
如果需要多次循环执行步骤607至610，相移控制器设置反射单元的相移值的具体方式为：相移控制器在循环中接收到相移处理器发送的多个相移阵列，并根据这些相移阵列更新反射单元的相移值。
可以理解的是，步骤607至610，为可选步骤，若在步骤604中，确定了所有智能反射面的反射单元的最佳相移阵列之后，则不需要执行步骤607至610。
