Description

一种通信方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
现有典型的蜂窝通信结构如图1所示，基站直接与终端进行通信，基站和终端都可以采取波束成型，使得信号能量集中于波束方向，提升传输性能。虽然借助于波束成型，可以提升信号传输的性能，然而受限于空间信道，并无法获得最佳效果。尤其是，对于非视距传输，无线通信信号往往被环境中的散射体或者阻挡物衰减严重，即使借助于高增益的波束，依然无法获得比较好的通信性能。
另外，基站也可以借助于中继器与终端进行通信，可以有效地扩大了信号。现有的中继器往往分为两种，一种为放大转发中继，一种为译码转发中继。其中放大转发中继将接受到的信号，经过射频电路的处理后，然后放大并发射。而译码转发中继则对接收信号进行译码，然后重新编码和经过一系列的信号处理后，将数据转发，以实现基站和终端之间的通信。中继器工作的时间和频率资源，一般是通过基站调度。虽然中继器可以扩展覆盖范围，但是对信号处理要求比较高，所以功耗比较大，造成部署困难，而且还可能导致延长信号处理时延。
因此，亟需一种通信方式可以克服上述问题，且能够保证终端与接入网设备之间的正常通信。
发明内容
本申请提供一种通信方法及装置，用以解决提供一种通信方式，可以有效地辅助终端与接入网设备之间进行通信。
第一方面，本申请实施例提供一种通信方法，该方法可由第一通信装置执行，该第一通信装置可以是反射器，或为能够支持反射器实现该方法所需的功能的通信装置，例如反射器包括的部件，或者反射器中的芯片系统等，示例性地，该方法由反射器执行。该方法包括：
反射器接收第一指示信息，第一指示信息用于指示所述反射器启动工作模式；反射器接收第二指示信息，第二指示信息用于指示反射器处于工作模式时占用的通信资源，通信资源包括时域资源、频域资源或码域资源中至少一种。需要说明的是，第一指示信息和第二指示信息可以在来自同一条消息，也可以来自不同的消息。之后，反射器在通信资源上向接入网设备或终端设备发送反射信号。
本申请实施例中，终端设备在需要辅助的时候才通知反射器启动辅助通信，反射器只有在接收到第一指示信息时，才会启动对信号的反射，反之，则不对信号进行反射，有助于节省反射器的功耗。
在一种可能的设计中，第二指示信息还包括反射器的标识；反射器在通信资源上向接入网设备或终端设备发送反射信号，包括：
当反射器确定第一指示信息包括所述反射器的标识时，在通信资源上向接入网设备发 送终端设备的反射信号。反之，当反射器确定第一指示信息中不包括反射器的标识时，则不向接入网设备或终端设备发送反射信号。
本申请实施例中，当终端设备周围存在多个反射器设备时，按照上述方式可以筛选出需要使用的反射器，从而触发该反射器启动反射工作，而终端设备周围的其它反射器则不会启动反射工作，有助于进一步地降低反射器的功耗。
在一种可能的设计中，第二指示信息还包括反射状态矩阵的索引，反射状态矩阵索引中的每个索引对应一个反射状态矩阵，反射状态矩阵指的是反射器的反射阵元和反射阵元的状态之间的对应关系。反射器在所述通信资源上向接入网设备或终端设备发送反射信号，包括：
反射器根据反射状态矩阵的索引，在通信资源上向接入网设备或终端设备发送反射信号。也就是说，反射器使用第一指示信息所指示的反射状态矩阵进行信号反射。
本申请实施例中，通过在第二指示信息携带反射状态矩阵的索引，有利于反射器根据索引确定需要启动反射的反射阵元，因反射状态矩阵的索引占用的比特位较小，有助于降低通信系统的系统开销。
在一种可能的设计中，反射器接收第三指示信息，第三指示信息用于指示反射器启动休眠模式；反射器停止向接入网设备或终端设备发送反射信号。
本申请实施例中，在终端不需要辅助的时候，则通知反射器不再工作，因此可以节省功耗。
第二方面，本申请实施例还提供一种通信方法，可以应用于第二通信装置，该第二通信装置可以是终端设备，或为能够支持终端设备实现该方法所需的功能的通信装置，例如终端设备包括的部件，或者终端设备中的芯片系统等，示例性地，该方法可以由终端设备执行，该方法包括：

所述终端设备向反射器发送第一指示信息，其中，所述第一指示信息用于指示所述反射器启动所述工作模式；
所述终端设备或接入网设备向反射器发送第二指示信息，所述第二指示信息用于指示所述通信资源；
当所述反射器启动所述工作模式时，所述终端设备在所述反射器的辅助通信下，在所述通信资源上与接入网设备通信。
本申请实施例中，终端设备在需要辅助的时候才通知反射器启动辅助通信，反射器只有在接收到第一指示信息时，才会启动对信号的反射，反之，则不对信号进行反射，有助于节省反射器的功耗。
在一种可能的设计中，终端设备向反射器发送第一指示信息，包括：
终端设备确定满足启动所述工作模式的触发条件中的至少一个条件时，向反射器发送第一指示信息；
其中，所述启动所述工作模式的触发条件包括下述中的至少一项：
测量到所述接入网设备发送的下行信号的信号质量低于第一信号质量门限值；
接收到设定下行信号；
确定当前执行的业务的服务质量不满足第一设定服务要求。
本申请实施例中，终端设备通过上述判断可以确定什么时候需要反射器的辅助通信从而在确定需要的时候才通知反射器启动辅助通信，有助于节省反射器的功耗。
在一种可能设计中，终端设备向反射器发送第一指示信息，包括：
所述终端设备在所述设定下行信号关联的物理随机接入信道资源上，向所述反射器发送所述第一指示信息。
本申请实施例中，选择设定下行信号关联的物理随机接入信道资源发送指示信息，可以降低通信系统的系统开销。
在一种可能的设计中，第二指示信息还包括反射状态矩阵的索引、反射器的工作频率或反射器的标识中的至少一个。
在一种可能的设计中，所述方法还包括：终端设备确定满足启动所述休眠模式的触发条件中的至少一个条件时，向反射器发送第三指示信息；所述第三指示信息用于指示启动所述休眠模式；
其中，所述启动所述休眠模式的触发条件包括下述中的至少一项：
测量到所述接入网设备发送的下行信号的信号质量高于第二信号质量门限值；
确定当前执行的业务的服务质量满足第二设定服务要求。
本申请实施例中，在终端不需要辅助的时候，则通知反射器不再工作，因此可以节省功耗。
第三方面，本申请实施例还提供一种通信方法，该方法可以应用于第三通信装置，该第三通信装置可以是接入网设备，或为能够支持接入网设备实现该方法所需的功能的通信装置，例如接入网设备包括的部件，或者接入网设备中的芯片系统等，示例性地，该方法可以由接入网设备执行，该方法包括：
接入网设备向反射器发送反射器调度信息，所述反射器调度信息包括所述反射器处于工作模式时占用的通信资源；接入网设备接收来自反射器在通信资源上发送的反射信号。
本申请实施例中，在反射器接收到反射器调度信息时，则证明终端设备需要辅助通信，因此反射器才开启进行反射，一定程度上可以节省功耗。
在一种可能的设计中，接入网设备向反射器发送反射信号之前，还包括：
接入网设备接收来自终端设备的第一请求消息，所述第一请求消息用于请求开启反射面辅助通信；接入网设备向反射器发送第一指示，所述第一指示用于指示反射器启动工作模式。
本申请实施例中，在反射器接收到反射器调度信息和第一指示时，则证明终端设备需要辅助通信，因此反射器才开启进行反射，一定程度上可以节省功耗。
在一种可能的设计中，接入网设备接收来自终端设备的第二请求消息，第二请求消息用于请求停止反射面辅助通信；

具体实施方式
本申请实施例可以应用于各种移动通信系统，例如：新无线(new radio，NR)系统、长期演进(long term evolution，LTE)系统、先进的长期演进(advanced long term evolution，LTE-A)系统、通用移动通信系统(universal mobile telecommunication system，UMTS)、演进的长期演进(evolved long term evolution，eLTE)系统、未来通信系统等其它通信系统，具体的，在此不做限制。示例性的，本申请实施例所应用的通信系统架构可以如图2A所示，包括：终端设备、反射器和接入网设备。
图2A中，终端设备发送的无线信号(又称为激励信号)，可以为单音信号(即连续的正弦波)或多音信号(即具有一定带宽的信号)，无线信号中可以携带发送给接入网设备的数据，也可以不携带发送给接入网设备的数据。
反射器接收到来自终端设备的无线信号之后，向接入网设备发送该反射信号。具体地，反射器上设有多个反射阵元，反射器通过控制反射阵元的通断状态，实现对反射阵元所接收的无线信号进行反射或吸收。另外反射器上的多个反射阵元还可以共同形成信号叠加，将信号反射到空间特定方向，从而增强特定方向上的终端和接入网设备之间通信的性能。 本申请实施例中，反射器可以为无源设备，即在接收无线信号以及发送反射信号的过程中不需要电源供电；反射器也可以为半有源设备，即在接收无线信号或发送反射信号的过程中需要电源供电，例如，控制反射开关通断的部分是有供电的。
接入网设备可以是能和终端设备通信的设备。接入网设备可以是基站、中继站或接入点。基站可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)，还可以是长期演进(long term evolution，LTE)中的eNB或eNodeB(evolutional NodeB)。基站设备还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。基站设备还可以是未来5G网络中的基站设备或者未来演进的PLMN网络中的网络设备。基站设备还可以是可穿戴设备或车载设备。
终端设备可以是用户设备(user equipment，UE)、接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、终端、终端、无线通信设备、终端代理或终端装置等。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的PLMN网络中的终端设备等。
需要说明的是，终端设备也可能存在其他名称，例如可以称为激励器、协助器(helper)、询问器(interrogator)、读写器(reader)、用户设备(user equipment，UE)等，为了描述方便，本申请实施例中均称为终端设备。相应的，反射器也可能存在其它名称，例如可以称为智能反射面(intelligent reflecting surface)，反射阵列，智能反射阵列(intelligent reflecting array)，反射器，智能反射器，反射设备(backscatter device)，无源设备(passive device)，半有源设备(semi-passive device)，散射信号设备(ambient signal device)等，为了描述方便，本申请实施例中均称为反射器。接入网设备也可能存在其他名称，例如可以称为接收器、接入点、基站等，为了描述方便，本申请实施例中均称为接入网设备。
在介绍本申请实施例之前，首先对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、调制、解调，调制就是对信号源的数据进行处理加到载波上，使其变为适合于信道传输的形式的过程。不同的模式就对应于不同的调制方法，例如多载波调制还是单载波调制，相移键控(phase-shift keying，PSK)调制还是振幅键控(amplitude-shift keying，ASK)调制等等。解调即调制的逆过程，从信号中恢复原始数据比特或符号，解调有时也可以称为检测。
2)、正交频分复用(orthogonal frequency division multiplex，OFDM)，是一种频分复用的多载波传输波形，参与复用的各路信号(也称为各路载波/子载波)是正交的。OFDM技术是通过串/并转换将高速的数据流变成多路并行的低速数据流，再将它们分配到若干个不同频率的子载波上传输。OFDM技术利用了相互正交的子载波，从而子载波的频谱是重叠的，传统的FDM多载波调制系统中子载波间需要保护间隔，与之相比，OFDM技术提高了频谱利用率。
3)、子载波，在多载波波形当中，传输的信号为带宽信号，带宽信号中有很多不同频 率的信号，这些频率的间隔都是相同的。这些不同频率称为子载波。网络设备与终端设备的数据可以调制到这些子载波上，这些子载波之间在一段时间内是正交的。以蜂窝系统现在支持的15KHz子载波间隔(subcarrier spacing，SCS)、30KHz SCS、60KHz SCS为例，子载波和子载波宽度如图2B所示，每一个频率域的空格为一个子载波，可以用来传输数据。
4)、参考信号(reference signal，RS)，根据功能参考信号可以分为解调参考信号(demodulation reference signal，DMRS)、信道状态信息参考信号(channel state information reference signal，CSI-RS)、相位跟踪参考信号(phase tracking reference signal，PTRS)等。是指发送端或者接收端已知或按照预定的规则可以推断信号所在的时间和频率位置，以及时间和频率上承载的信号/符号所经历的信道或者其他不可预期的现象。参考信号用于获取信号在传输中所受外界(例如，空间信道、发送或接收端器件非理想性)影响的已知信号，一般用于进行信道估计、辅助信号解调、检测。例如DMRS和CSI-RS用于获取信道信息，PTRS用于获取相位变化信息。
需要说明的是，本申请实施例描述的通信系统以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图详细说明本申请实施例。另外，需要理解，在本申请实施例中，至少一个还可以描述为一个或多个，多个可以是两个、三个、四个或者更多个，本申请不做限制。
在本申请实施例中，“/”可以表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；“和/或”可以用于描述关联对象存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，其中A，B可以是单数或者复数。为了便于描述本申请实施例的技术方案，在本申请实施例中，可以采用“第一”、“第二”等字样对功能相同或相似的技术特征进行区分。该“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。在本申请实施例中，“示例性的”或者“例如”等词用于表示例子、例证或说明，被描述为“示例性的”或者“例如”的实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
在反射辅助的通信中，当多个反射器与接入基站后，如果UE并不需要与基站进行通信，反射器上的反射阵元始终反射无线信号或吸收无线信号，则反射器的功耗就比较大，另外也会给网络带来信号干扰。
虽然，目前还存在其它信号传输方法可以提高信号传输性能，但也存在一定的局限性。如基站和终端都可以采取波束成型，使得信号能量集中于波束方向，提升传输性能。虽然借助于波束成型，可以提升信号传输的性能，然而受限于空间信道，并无法获得最佳效果。尤其是，对于非视距传输，无线通信信号往往被环境中的散射体或者阻挡物衰减严重，即使借助于高增益的波束，依然无法获得比较好的通信性能。再比如，目前基站可以借助于中继器与终端进行通信。虽然中继器可以扩展覆盖范围，但是对信号处理要求比较高，所以功耗比较大，造成部署困难，而且还可能导致延长信号处理时延。
本发明提供一种通信方法，该方法通过反射器辅助终端与接入网设备之间进行通信， 并且在反射器辅助的通信过程中，指示反射器在终端或接入网设备需要的时候处于工作模式，达到辅助通信的效果，以及指示反射器在终端或接入网设备需要的时候处于休眠模式，达到节省功耗的目的。如图3所示，终端设备或网络设备通过向反射器发送不同的指示信息，达到触发反射器进入工作模式或休眠模式的目的。
如图4所示，为反射器的一种结构示例，逻辑上包含多个部分，分别为反射器通信功能单元401、反射阵元控制器402、反射阵元403。反射器通信功能单元401用于和接入网设备或终端设备进行数据通信，反射阵元控制器402用于根据接收到的信令对各个反射阵元的状态进行控制。反射阵元403用于实现对信号的反射或吸收等动作。反射器通信功能单元401和反射阵元控制器402可以是有源的，反射阵元403是无源的。
反射阵元的基本工作原理为通过简单的电路，在对接收到的信号进行反射或者吸收。反射阵元反射的时候，还可以对反射信号叠加一个相位或幅度，然后反射。反射阵元的不同状态，可以实现在接收到的信号上，叠加(或者乘上)不同的幅度(或者，控制反射信号或吸收信号等动作)和/或相位。示例性地，比较简单的反射阵元为通断两状态反射，即反射阵元的两个状态分为反射信号、吸收信号。处于反射状态时，反射阵元将接收到的信号直接反射出去，处于吸收状态时，反射阵元将接受到的信号吸收。
反射状态矩阵(或称为反射状态向量、反射状态、反射矩阵、反射向量)，指的是反射器的反射阵元和反射阵元的状态之间的对应关系。反射状态矩阵索引中的每个索引对应一个反射状态矩阵。示例性地，假设反射器有N个反射阵元，反射状态矩阵S为N 0×N 1的矩阵，总共有N 0×N 1＝K个反射状态矩阵。例如，N 0×N 1表示有N 0行以及N 1列的反射器阵列，分别对应的位于行方向的N 0个反射器、列方向的N 1个反射器。再例如，反射状态矩阵S的各个元素取值为{0,1}，表示每个反射器可以工作在两个状态：反射(用1表示)，不反射(用0表示)。再例如，K个反射状态矩阵由
Figure PCTCN2020124027-appb-000001
个比特的字段来指示，字段的取值即索引，例如索引为001的矩阵S仅有三个位置为1，分别为(X1，Y1)、(X2、Y2)以及(X3、Y3)；表示位置(X1，Y1)、(X2、Y2)以及(X3、Y3)的反射阵元处于接通状态，而其余反射阵元处于断开状态。
在另外的实现方式中，反射状态矩阵还可以通过时间、频率、码域等发送的信号表示。例如，参考信号reference signal；再例如，数据信号；再例如，参考信号和数据信号。即，全文实施例中“反射状态矩阵”可以替换成对应的“反射器信号”、或全文中“反射状态矩阵索引”可以替换成对应的“反射器信号索引”。
例如，反射器在K个时间上反射了L个参考信号和/或数据信号，则所述K个时间资源(或者其对应的时间索引、频率索引、码域索引等至少一个)可以代表K个反射状态矩阵，或者所述K个时间资源上的信号(或者其对应的时间索引、频率索引、码域索引等至少一个)可以代表K个反射状态矩阵。
例如，反射器在K个时间上反射了L个参考信号和/或数据信号，则所述L个信号可以代表L或者K个反射状态矩阵。
下面结合多个实施例对本申请所提供的通信方法进行展开说明。
【实施例一】
图5为本申请实施例提供的一种通信方法流程示意图，该方法包括如下步骤：
S501，接入网设备向终端设备发送反射器调度信息和终端设备配置信息中的至少一项。
具体地，在进行反射器辅助通信之前，接入网设备可以通过无线资源控制(radio  resource control，RRC)信令、媒介接入控制-控制元素(medium access control-control element，MAC CE)、媒介接入控制-协议数据单元(medium access control–protocol data unit，MAC PDU)、下行控制信息(downlink control information，DCI)、系统消息等中的至少一项，向终端设备发送的反射器调度信息和/或终端设备配置信息。
其中，终端设备配置信息包括：反射链路的资源信息，如时域资源、频域资源和码域资源中的至少一种(包括信号时间粒度、长度和周期等)，还可以包括触发反射器处于工作模式所需的参数，如参考信号接收功率(reference signal receiving power，RSRP)的门限值、参考信号接收质量(reference signal receiving quality，RSRQ)的门限值等。其中，反射链路是指终端设备或接入网设备到反射器之间的通信链路。
反射器调度信息包括：反射信号速率、反射器处于工作模式的资源信息，如时域资源、频域资源和码域资源中的至少一种(包括起始时间、时间长度、周期等中的一项或多项)，还可以包括反射器的标识(如反射器的编号)、反射状态矩阵索引(或者编号)。
在一种可能的实施例中，在执行步骤501之前，接入网设备先与反射器建立连接，接入网设备先与反射器进行时间同步，然后从反射器获取反射器所支持的反射状态矩阵数量、反射状态矩阵与下行信号的对应关系、反射状态矩阵与覆盖区域(或者地理位置)的对应关系、反射能力等至少一种信息。从而，接入网设备在获取这些信息之后，生成反射器调度信息，以便于控制相应反射器的反射状态矩阵进行信号反射。
在一种可能的实施例中，接入网设备还可能会周期性(或者非周期)地向终端设备发送下行信号(如同步信号(synchronization signal，SS)/广播信道块(physical broadcast channel block，PBCH)，在协议中也会简称为SSB或者信道状态信息参考信号(channel status information reference signal，CSI-RS))，该下行信号用于终端与接入网设备之间进行时频同步。
S502，终端设备接收来自接入网设备的反射器调度信息和终端设备配置信息中的至少一项。
进一步，终端设备可以根据接收的反射器调度信息，确定终端周围是否存在反射器，以及反射器处于工作模式的时频资源信息、码域资源信息等。
S503，终端设备确定是否满足启动反射器的工作模式的触发条件。
具体地，一种可能的情况下，若终端设备从设定下行信号所关联的系统消息中接收了反射器调度信息和/或终端设备配置信息，则终端设备确定满足触发条件。设定的下行信号可以是接入网设备所指定的，设定下行信号所关联的系统消息可以是1号系统信息块(system information block，SIB)，或者其它编号的SIB，甚至于主信息块(master information Block，MIB)。
另一种可能的情况下，终端设备可以根据信号质量、业务质量(quality of service，QoS)、功率余量、信号阻挡情况(例如，终端可以感知终端天线被人体等的阻挡情况)中的至少一项，确定是否满足触发反射器启动工作模式的触发条件。其中业务质量可以指：传输速率(或者相关的调制编码策略(modulation coding scheme，MCS)、信道质量信息(channel quality information，CQI)、预编码矩阵索引(precoding matrix index，PMI)、秩信息(rank information，RI)、功率余量等等)、传输时延要求等。
示例性地，终端设备测量到的下行信号的信号质量低于第一信号质量门限值，则触发反射器启动工作模式；再比如，终端设备测量到的业务的服务质量不满足第一设定服务要 求，则触发反射器启动工作模式。所谓工作模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号进行反射，或者说反射器辅助终端设备和接入网设备之间进行通信。
S504，当满足工作模式的触发条件时，终端设备向反射器发送第一指示信息和第二指示信息。
其中，第一指示信息用于指示反射器启动工作模式，第二指示信息用于指示反射器处于工作模式时占用的通信资源，以及反射矩阵索引中的至少一项，该通信资源包括时域资源、频域资源或码域资源中至少一种。第一指示信息和第二指示信息可以承载于同一条消息中，也可以承载于不同的消息中。示例性地，该第一指示信息(或第二指示信息)可以承载于物理随机接入信道(physical random access channel，PRACH)，或者，该第一指示信息(或第二指示信息)可以承载于探测参考信号(sounding reference signal，SRS)。PRACH或SRS所对应的序列(包括根序列、序列的逻辑编号)、所在的时频资源等是由接入网设备指示的。为节省信令开销，终端设备可以在同步信号关联的PRACH资源上，向所述反射器发送指示信息。
具体地，终端设备可以利用接入网设备所配置的反射链路资源向反射器发送第一指示信息和第二指示信息；或者，终端设备从接入网设备所配置的反射链路资源中选择至少一个时频资源发送第一指示信息和第二指示信息。
S505，反射器在接收到第一指示信息和第二指示信息之后，启动工作模式。
也就是说，反射器在接收第二指示信息之后，根据第二指示信息确定工作模式的时域资源、频域资源和码域资源等，以及反射器根据第二指示信息确定反射器的反射状态矩阵，然后该反射状态矩阵中的反射阵元进行信号反射。
S506，在反射器的反射辅助下，接入网设备与终端设备进行上下行通信。
也就是说，当反射器启动工作模式之后，反射器就可以按照相应的反射状态矩阵，在第二指示信息所指示的资源上进行信号反射。
需要说明的是，在终端设备通过反射器辅助通信的过程中，终端设备还会实时监测终端设备的信号质量或业务质量是否仍满足反射器的工作模式的触发条件，若满足，则终端设备继续通过反射器进行辅助通信。可选地，若终端设备的信号质量或业务质量不满足反射器的工作模式的触发条件，则终端设备继续执行下述步骤，以确定是否将反射器从工作模式切换为休眠模式。
S507，终端设备确定是否满足反射器的休眠模式的触发条件。
一种可能的情况下，如图5所示，终端设备可以根据信号质量、业务质量(quality of service，QoS)、功率余量、信号阻挡情况(例如，终端可以感知终端天线被人体等的阻挡情况)中的至少一项，确定是否满足触发反射器启动休眠模式的触发条件。示例性地，终端设备测量到的下行信号的信号质量高于第二信号质量门限值，则触发反射器启动休眠模式；再比如，终端设备测量到的业务的服务质量高于第二设定服务要求，则触发反射器启动休眠模式。所谓休眠模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号均不反射，或者说反射器不辅助终端设备与接入网设备之间进行通信。
S508，当满足休眠模式的触发条件时，终端设备向反射器发送第三指示信息。
其中，第三指示信息用于指示反射器启动休眠模式。
示例性地，该第三指示信息可以承载于物理随机接入信道(physical random access channel，PRACH)，或者，该第三指示信息可以承载于探测参考信号(sounding reference signal，SRS)。PRACH或SRS所对应的序列(包括根序列、序列的逻辑编号)、所在的时频资源等是由接入网设备指示的。为节省信令开销，终端设备可以在同步信号关联的PRACH资源上，向所述反射器发送指示信息。
需要说明的是，在另一种可能的实施例中，上述S507至S508也可以被替换为如下可能的实施例：
另一种可能的情况下，反射器也可以根据信号质量、业务质量、信号阻挡情况(例如，终端可以感知终端天线被人体等的阻挡情况)中的至少一项，确定是否满足触发反射器启动休眠模式的触发条件。示例性地，发射器测量到的来自终端设备的下行信号的信号质量高于第二信号质量门限值，则触发反射器启动休眠模式；再比如，发射器测量到来自终端设备的无线信号的业务的服务质量高于第二设定服务要求，则触发反射器启动休眠模式。所谓休眠模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号均不反射，或者说反射器不辅助终端设备与接入网设备之间进行通信。
S509，反射器启动休眠模式。
或者是，反射天线对接收到的终端设备的无线信号均吸收，又或者说反射器不辅助终端设备与接入网设备之间进行通信。
S510，接入网设备和终端设备直接进行上下行通信。
需要说明的是，本实施例中的“工作模式”有可能存在其它替代性的描述方式，如工作状态、反射模式、反射状态、操作状态等。对应的，本实施例中的“休眠模式”有可能存在其它替代性的描述方式，如休眠状态、吸收模式、吸收状态、关闭状态等。
本申请实施例中，终端设备在需要辅助的时候才通知反射器启动辅助通信，而在终端不需要辅助的时候，则通知反射器不再工作，因此可以节省功耗，另外，一定程度上可以改善反射器给网络带来的信号干扰。

图6为本申请实施例提供的另一种通信方法流程示意图，该方法包括如下步骤：
S601，终端设备确定是否满足启动反射器的工作模式的触发条件。
具体地，终端设备可以根据信号质量、业务质量(quality of service，QoS)、功率余量、信号阻挡情况(例如，终端可以感知终端天线被人体等的阻挡情况)中的至少一项，确定是否满足触发反射器启动工作模式的触发条件。示例性地，终端设备测量到的下行信号的信号质量低于第一信号质量门限值，则触发反射器启动工作模式；再比如，终端设备测量到的业务的服务质量不满足第一设定服务要求，则触发反射器启动工作模式。所谓工作模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号进行反射，或者说反射器辅助终端设备和接入网设备之间进行通信。
具体地，在执行S601之前，终端设备先接入接入网设备，具体接入方法可以基于当前LTE或者NR中的UE接入网络的流程，在此不再赘述。终端设备可以在接入后或者在接入过程中，从接入网设备侧获知是否存在反射器，或者获知是否有反射器可以辅助接入网设备和终端设备之间的通信。例如，终端设备通过来自接入网设备的随机接入消息2(Msg2)或随机接入消息4(Msg4)获知反射器的存在。再比如，基站可以通过无线资源 控制(radio resource control，RRC)信令、媒介接入控制-控制元素(medium access control–control element，MAC-CE)、下行控制信息(downlink control information，DCI)等信息通知终端设备反射器的存在。
S602，当满足工作模式的触发条件时，终端设备向接入网设备发送第一请求消息，该第一请求消息用于请求接入网设备开启反射器的工作模式。

S605，反射器在接收到第一指示信息和第二指示信息之后，启动工作模式。
也就是说，反射器在接收第二指示信息之后，根据第二指示信息确定工作模式的时域资源、频域资源和码域资源等，以及反射器根据第二指示信息确定反射器的反射状态矩阵，然后该反射状态矩阵中的反射阵元进行信号反射。
在一种可能的实施方式中，终端设备和反射器同时接收接入网设备的下行控制信息，反射器通过获得控制信息，确定开启反射面的时间。如果终端设备和反射器的下行控制信息是相同的信道承载(例如同一个PDCCH的DCI)，则反射器和终端设备都需要知道该PDCCH对应的时间、频率位置，以及对应的C-RNTI，该通知信息由接入网设备通知反射器。
S606，在反射器的反射辅助下，接入网设备与终端设备进行上下行通信。
也就是说，当反射器启动工作模式之后，反射器就可以按照相应的反射状态矩阵，在第二指示信息所指示的资源上进行信号反射。具体地，在反射器辅助通信下，终端向接入网设备发送信息，和/或接入网设备向终端发送信息。
需要说明的是，在终端设备通过反射器辅助通信的过程中，终端设备还会实时监测终端设备的信号质量或业务质量是否仍满足反射器的工作模式的触发条件，若满足，则终端 设备继续通过反射器进行辅助通信。可选地，若终端设备的信号质量或业务质量不满足反射器的工作模式的触发条件，则终端设备继续执行下述步骤，以确定是否将反射器从工作模式切换为休眠模式。所谓休眠模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号均不反射，或者说反射器不辅助终端设备与接入网设备之间进行通信。
S607，终端设备确定是否满足反射器的休眠模式的触发条件。
具体地，终端设备可以根据信号质量、业务质量(quality of service，QoS)、功率余量、信号阻挡情况(例如，终端可以感知终端天线被人体等的阻挡情况)中的至少一项，确定是否满足触发反射器启动休眠模式的触发条件。示例性地，终端设备测量到的下行信号的信号质量高于第二信号质量门限值，则触发反射器启动休眠模式；再比如，终端设备测量到的业务的服务质量高于第二设定服务要求，则触发反射器启动休眠模式。所谓休眠模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号均不反射，或者说反射器不辅助终端设备与接入网设备之间进行通信。

示例性地，该第三指示可以通过反射器的反射链路控制信息、反射链路无线资源控制消息、反射链路媒介接入控制消息等中的至少一个。
需要说明的是，在另一种可能的实施例中，上述S607至S609也可以被替换为如下可能的实施例：
另一种可能的情况下，反射器也可以根据信号质量、业务质量、信号阻挡情况(例如，终端可以感知终端天线被人体等的阻挡情况)中的至少一项，确定是否满足触发反射器启动休眠模式的触发条件。示例性地，发射器测量到的来自终端设备的下行信号的信号质量高于第二信号质量门限值，则触发反射器启动休眠模式；再比如，发射器测量到来自终端设备的无线信号的业务的服务质量高于第二设定服务要求，则触发反射器启动休眠模式。所谓休眠模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号均不反射，或者说反射器不辅助终端设备与接入网设备之间进行通信。
S610，反射器启动休眠模式。
或者是，反射天线对接收到的终端设备的无线信号均吸收，又或者说反射器不辅助终端设备与接入网设备之间进行通信。
S611，接入网设备和终端设备直接进行上下行通信。
需要说明的是，本实施例中的“工作模式”有可能存在其它替代性的描述方式，如工作状态、反射模式、反射状态、操作状态等。对应的，本实施例中的“休眠模式”有可能存在其它替代性的描述方式，如休眠状态、吸收模式、吸收状态、关闭状态等。
本申请实施例中，在终端设备接入接入网设备之后，由终端设备在需要辅助通信的时候，请求接入网设备触发反射器辅助通信，接入网设备指示反射器辅助终端发送，反射器根据指示信息中包含的时间、频率信息进行反射信号。由终端设备在不需要辅助通信的时候，请求接入网设备触发反射器停止辅助通信，则接入网设备指示反射器不再工作，因此可以节省功耗，另外，一定程度上可以改善反射器给网络带来的信号干扰。
【实施例三】
图7为本申请实施例提供的另一种通信方法流程示意图，该方法包括如下步骤：
S701，接入网设备确定反射器调度信息，反射器调度信息包括处于工作模式时占用的通信资源、反射器的标识以及反射矩阵索引中的至少一项。
其中，该反射器处于工作模式时占用的通信资源包括：反射器处于工作模式的资源信息，如时域资源、频域资源和码域资源中的至少一种(包括起始时间、时间长度、周期等中的一项或多项)，还可以包括反射器的标识(如反射器的编号)、反射状态矩阵索引(或者编号)。例如，反射器调度信息包括反射面开启工作模式的时间、反射状态矩阵索引等，可选地，如果反射器可以基于某个特定频段进行反射，则反射器调度信息包括反射器的频率位置，例如载频。
需要说明的是，接入网设备还可以与终端设备和反射器进行信令交互，以确定出最优或较优的反射状态矩阵，从而确定出反射器调度信息中的反射状态矩阵索引。
S702，接入网设备向反射器发送反射器调度信息。
S703，反射器在接收到反射器调度信息，确定工作模式对应的第一时间区域和反射矩阵索引，以及休眠模式对应的第二时间区域。
也就是说，反射器在接收反射器调度信息，确定在第一时间区域上启动工作模块，以及在第二时间区域上启动休眠模式，以及反射器进行辅助通信所需的载频、码域资源等。
在一种可能的实施方式中，终端设备和反射器同时接收接入网设备的下行控制信息，反射器通过获得控制信息，确定开启反射面的时间。如果终端设备和反射器的下行控制信息是相同的信道承载(例如同一个PDCCH的DCI)，则反射器和终端设备都需要知道该PDCCH对应的时间、频率位置，以及对应的C-RNTI，该通知信息由接入网设备通知反射器。
S704，在第一时间区域，在反射器的反射辅助下，接入网设备与终端设备进行上下行通信。

S705，在第二时间区域，接入网设备和终端设备直接进行上下行通信。
也就是说，当反射器启动休眠模式时，反射器不再向终端设备反射信号。
需要说明的是，所谓工作模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号进行反射，或者说反射器辅助终端设备和接入网设备之间进行通信。所谓休眠模式指的是反射器的反射天线对接收到的来自终端设备或接入网设备的无线信号均不反射，或者说反射器不辅助终端设备与接入网设备之间进行通信。本实施例中的“工作模式”有可能存在其它替代性的描述方式，如工作状态、反射模式、反射状态、操作状态等。对应的，本实施例中的“休眠模式”有可能存在其它替代性的描述方式，如休眠状态、吸收模式、吸收状态、关闭状态等。
本申请实施例中，终端设备并不需要确定周围是否存在反射器，也就是说反射器对终端设备来说是无感知的。接入网设备指示反射器在第一时间区域上辅助终端与接入网设备 之间进行通信，指示反射器在第二时间区域上不再辅助终端与接入网设备之间进行通信，则反射器不再工作，因此可以节省功耗，另外，一定程度上可以改善反射器给网络带来的信号干扰。
