可以理解的是，本公开中“多个”是指两个或两个以上，其它量词与之类似。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，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。字符“/”一般表示前后关联对象是一种“或”的关系。单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。
为了便于理解，首先介绍本申请涉及的术语。
1、智能中继(smart repeater)
智能中继，可以为任意一种至少能定向放大信号的网络设备，或者，具有定向放大信号功能的终端设备。
2、智能超表面(Reconfigurable intelligence surface，RIS)
智能超表面RIS，也被称为“可重构智能表面”或者“智能反射表面”。从外表上看，RIS是一张平平无奇的薄板。但是，它可以灵活部署在无线通信传播环境中，并实现对反射或者折射电磁波的频率、相位、极化等特征的操控，从而达到重塑无线信道的目的。具体地说，RIS可以通过预编码技术，将入射到其表面的信号反射到特定的方向，从而增强接收端信号强度，实现对信道的控制。
由于smart repeater和RIS在网络交互时具有类似的特性，因此，本公开中，智能中继，代指smart repeater和RIS。
3、无线资源控制(Radio Resource Control，RRC)
无线资源控制(radio resource control，RRC)，又称为无线资源管理或者无线资源分配，是指通过一定的策略和手段进行无线资源管理、控制和调度，在满足服务质量的要求下，尽可能地充分利用有限的无线网络资源，确保到达规划的覆盖区域，尽可能地提高业务容量和资源利用率。
4、媒体接入控制(medium access control,MAC)控制单元(Control Element，CE)
MAC CE是在无线资源控制(radio resource control,RRC)消息和非接入层(non access stratum，NAS)消息之外，UE和网络之间的交换控制信息的一个途径，它交换的是关于MAC层的控制信息。
5、下行控制信息(Downlink Control Information，DCI)
DCI为在物理下行控制信道(Physical Downlink Control Channel，PDCCH)传输的、与物理上下行共享信道(PUSCH、PDSCH)相关的控制信息，这些DCI信息包含了诸如资源块(resource block，RB)分配信息、调制方式等等若干相关内容。终端只有正确的解码到了DCI信息，才能正确的处理PDSCH数据或PUSCH数据。

请参见图2，图2是本公开实施例提供的一种智能中继服务链路的波束指示方法的流程示意图,该方法由智能中继执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤21，接收无线资源控制RRC消息，其中，RRC消息用于为智能中继配置服务链路service link对应的波束的信息。
可以理解的是，在智能中继的回程链路中，智能中继使用的波束特征与终端设备相似，在服务链路中，智能中继使用的波束特征与网络设备相似，需要满足网络设备的波束赋形的要求，即服务链路的波束赋形与相关技术中指示终端设备如何波束赋形的技术不同。因此，本公开中，通过网络设备为智能中继配置服务链路service link对应的波束的信息，从而使智能中继可以基于服务链路对应的波束信息与终端设备进行通信。
可选的，波束的信息可以包括以下至少一项：一组波束的标识(identification，ID)；多组波束的标识；一个波束的标识；多个波束的标识；周期；波束的起始位置；及波束的时间特性。
其中，波束的标识可以为任一可以唯一确定波束的信息，其可以为传输配置指示(Transmission Configuration Indicator，TCI)标识或者空间关系信息(Spatial relation info)，或者参考信号标识等。比如，波束ID，可以通过参考信号来指示，以在DCI中进行波束指示为例，可以在DCI里包含一个参考信号ID用以表示一个波束ID，参考信号ID可以是信道状态信息参考信号资源标识(CSI-RS resource ID，CRI)，探测信号资源标识(SRS-resource ID，SRI)或者同步信号块序号(SS block index，SSBI)。或者，可以把参考信号ID配置在TCI中，DCI中包含该TCI，TCI中D类准共址(quasico-location,QCL)参数qcl-type-D对应的参考信号ID表示波束ID。上述参考信号可以是RRC配置的一个周期性参考信号，非周期性参考信号或者半静态参考信号。本公开对此不做限定。
其中，波束的起始位置及周期可以通过时间单元指示，比如，波束的起始位置可以为接收到RRC消息之后的第x个时间单元对应的时域位置，或者波束的使用周期为Y个时间单元等等，本公开对此不做限定。其中，时间单元，可以为时隙，微时隙，符号等等，其可以通过协议约定的，本公开对此不做限定。
其中，波束配置的标识，为网络设备通过RRC向智能中继进行波束配置时的标识。一个波束配置的标识可以对应以下参数组中的一个或多个：一组波束标识、波束循环周期、波束的的起始位置；或者，一个波束标识、波束循环周期、波束的起始位置；或者，一组波束标识、波束循环周期；或者，一个波束标识、波束循环周期；或者，一组波束标识。
另外，波束的时间特性，用于表示当前配置的波束为：周期性波束、半静态波束或非周期性波束等等，本公开对此不做限定。
本公开实施例中，智能中继通过接收网络设备发送的用于配置service link对应的波束的信息的RRC消息，进而可以基于配置的波束信息与终端设备进行通信。由此，实现了智能中继类似网络设备的 波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。
请参见图3，图3是本公开实施例提供的一种智能中继服务链路的波束指示方法的流程示意图,该方法由智能中继执行。如图3所示，该方法可以包括但不限于如下步骤：
步骤31，接收无线资源控制RRC消息，其中，RRC消息用于为智能中继配置服务链路service link对应的波束的信息。
其中，步骤31的具体实现形式，可参照本公开其他各实施例中的详细描述，此处不再详细赘述。
步骤32，根据RRC消息中第一预设参数的取值，确定配置的波束的周期。
需要说明的是，为了满足不同类型波束配置的一致性，本公开中，可以设置RRC消息中第一预设参数用于表征配置的波束的周期。从而智能中继在接收到RRC消息后，即可对该RRC消息进行解析，以确定配置的波束的周期。
可选的，在根据RRC消息中第一预设参数的取值，确定配置的波束的周期为第一数值的情况下，可以确定网络设备为服务链路配置的波束为周期性波束，进而智能中继可以基于配置波束对应的周期，循环使用波束。
或者，在根据RRC消息中第一预设参数的取值，确定配置的波束的周期为第二数值的情况下，可以确定配置的波束为非周期性波束。
其中，第一数值和第二数值可以根据需要设置、且第一数值与第二数值取值不同。比如，第一数值为实际的周期值，第二数值为0，或者，第二数值为空(NULL)等等，本公开对此不做限定。
可以理解的是，对于非周期性波束，RRC消息中可以不包含非周期性波束对应的周期。但是，为了保证波束配置的标识的一致性，也可以将非周期性波束对应的第一预设参数值设置为第二数值。
需要说明的是，在RRC消息中包含一个波束的情况下，第一预设参数的取值为一个。在RRC消息中包含多个波束的情况下，第一预设参数的取值可以为一个，也可以为多个，即多个波束对应的第一预设参数的取值可以相同，也可以不同。本公开对此不做限定。
步骤33，根据RRC消息中第二预设参数的取值，确定配置的波束的起始位置。
可以理解的是，对于周期性波束循环及周期性固定波束而言，网络设备发送的RRC消息中可以包含每个波束的对应的起始位置，而对于半静态波束循环、半静态固定波束指示、动态波束循环、及动态波束指示，RRC消息中可以不包含波束对应的起始位置。但是，为了保证波束配置的一致性，本公开中，可以设置RRC消息中的第二预设参数的取值，用于表征配置的波束的起始位置。
可选的，第二预设参数的取值，可以为周期性波束循环及周期性固定波束的起始位置，或者也可以为0或者空，本公开对此不做限定。
需要说明的是，在RRC消息中包含一个波束的情况下，第二预设参数的取值为一个。在RRC消息中包含多个波束的情况下，第二预设参数的取值可以为一个也可以为多个，即多个波束对应的第一预设参数的取值可以相同，也可以不同。本公开对此不做限定。
即，对于周期性波束循环，RRC消息配置的波束的信息中至少包含一组波束的标识，周期以及起始位置。而对于周期性固定波束指示，RRC消息配置的波束的信息中至少包含一个波束的标识，周期以及起始位置。
或者，对于半静态波束循环，RRC消息配置的波束的信息中至少包含一组波束的标识及周期。而对于半静态固定波束指示，RRC消息配置的波束的信息中至少包含一个波束的标识及周期。或者，对于动态波束循环及动态波束指示，RRC消息配置的波束的信息中至少包含一组波束的标识。
本公开实施例中，智能中继先接收网络设备发送的用于配置service link对应的波束的信息的RRC消息，之后根据RRC消息中第一预设参数的取值，确定配置的波束的周期，根据RRC消息中第二预设参数的取值，确定配置的波束的起始位置。由此，智能中继即可根据波束的周期及起始位置，实现智能中继类似网络设备的波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。
请参见图4，下面以半静态波束循环、及半静态固定波束指示场景为例，对本公开提供的智能中继服务链路的波束指示方法进行说明。图4是本公开实施例提供的一种智能中继服务链路的波束指示方法 的流程示意图,该方法由智能中继执行。如图4所示，该方法可以包括但不限于如下步骤：
步骤41，接收无线资源控制RRC消息，其中，RRC消息用于为智能中继配置服务链路service link对应的波束的信息。
其中，步骤41的具体实现形式，可参照本公开其他各实施例中的详细描述，此处不再详细赘述。
步骤42，接收第一指示信息，其中，第一指示信息用于触发或激活RRC消息配置的波束中的至少一个波束。
可以理解的是，对于半静态波束循环、及半静态固定波束指示而言，RRC消息配置的波束信息中不包含每个波束对应的起始时间，因此，可以通过第一指示信息，对RRC消息配置的波束中的至少一个波束进行激活或触发，进而向终端设备发送被激活或触发的波束，以保证与终端设备的通信。
可选的，第一指示信息中可以包括以下至少一项：
波束配置的标识；
多组波束的标识；
一组波束的标识；
多个波束的标识；及一个波束的标识。
可选的，网络设备可以通过DCI向智能中继发送第一指示信息，也可以通过MACCE向智能中继发送第一指示信息，本公开对此不做限定。
可选的，在智能中继为网络设备的情况下，智能中继可以通过下行控制信息DCI接收第一指示信息。
或者，在智能中继为具有中继功能的终端设备的情况下，智能中继可以通过媒体接入控制MAC控制单元CE接收第一指示信息。
可以理解的是，在智能中继为网络单元的情况下，由于网络单元中不存在数据的传输，不需要指示传输数据所使用的域，所以DCI的开销较小。因此，网络设备通过DCI触发RRC消息配置的波束中的至少一个波束，可以节省资源，提高波束配置的效率。
而在智能中继为具有中继功能的终端设备的情况下，具有中继功能的终端设备中可能存在数据的传输，若用DCI指示RRC消息配置的波束中的至少一个波束，不能准确地确定波束是否激活，还会增加DCI的开销。但是，MACCE具有良好的扩展性，且MACCE有与之对应的确认信令，可以确认波束是否激活，因此，网络设备通过MAC CE激活RRC消息配置的波束中的至少一个波束，可以保证信息的可靠传输。
本公开实施例中，智能中继先接收网络设备发送的用于为智能中继配置service link对应的波束的信息的RRC消息，之后在接收网络设备发送的触发或激活RRC消息配置的波束中的至少一个波束的第一指示信息后，即可基于第一指示信息激活或触发的至少一个波束与终端设备进行通信。由此，实现智能中继类似网络设备的波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。

步骤52，接收第一指示信息，其中，第一指示信息用于触发或激活RRC消息配置的波束中的至少一个波束。
其中，步骤51及步骤52的具体实现形式，可参照本公开其他各实施例中的详细描述，此处不再详细赘述。
步骤53，接收第三指示信息，其中，第三指示信息用于指示第一指示信息触发或激活的至少一个波束中的至少一个波束。
可以理解的是，对于动态波束循环、及动态波束指示，网络设备配置的RRC消息中不包含每个非周期性波束对应的使用时间信息，因此，智能中继需要网络设备发送第三指示消息对RRC消息配置的波束或通过MAC CE已经激活的至少一个波束中的至少一个波束进行触发，进而向终端设备发送被触发的波束，以保证与终端设备的通信。
可选的，第三指示信息中可以包括以下至少一项：
波束配置的标识；
多组波束的标识；
一组波束的标识；
多个波束的标识；及一个波束的标识。
可选的，智能中继可以通过下行控制信息DCI接收第三指示信息。
本公开实施例中，智能中继先接收网络设备发送的用于配置service link对应的波束的信息的RRC消息，之后接收网络设备发送的用于激活RRC消息配置的波束中的至少一个波束的第一指示信息，最后接收网络设备发送的用于指示第一指示信息激活的至少一个波束中的至少一个波束的第三指示信息。由此，智能中继可以根据第三指示信息指示的波束与终端设备进行通信，从而实现智能中继类似网络设备的波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。

其中，步骤63的具体实现形式，可参照本公开其他各实施例中的详细描述，此处不再详细赘述。
步骤64，确定接收到DCI之后的第一数量个时间单元对应的时域位置，为至少一个波束的起始位置。
其中，时间单元，可以为时隙，微时隙，符号等等，其可以通过协议约定确定，或者，也可以由网络设备指示，本公开对此不做限定。
可选的，智能中继可以根据网络设备的指示，确定第一数量个时间单元的取值。或者，智能中继也可以协议约定及至少一个波束的类型，确定第一数量个时间单元的取值。

可以理解的是，智能中继在确定了至少一个波束的起始位置，进而可以该波束的起始位置，利用该波束与终端设备进行通信。
本公开的一个实施例中，智能中继先接收网络设备发送的用于配置service link对应的波束的信息的RRC消息，之后接收网络设备发送的用于指示RRC配置的波束的类型的第二指示信息，再通过DCI接收网络设备发送的用于触发RRC消息配置的波束中的至少一个波束的第一指示信息，最后确定接收到DCI的第一数量个时间单元之后，为至少一个波束的起始位置。由此，智能中继在确定了DCI触发的至少一个波束对应的起始位置之后，即可根据该波束的起始位置发送对应的波束，从而实现中继类似网络设备的波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。

步骤93，向智能中继发送无线资源控制RRC消息，其中，RRC消息用于为智能中继配置服务链路service link对应的波束的信息。
其中，步骤93的具体实现形式，可参照本公开其他各实施例中的详细描述，此处不再详细赘述。
通过实施本公开实施例，网络设备先根据待配置的波束是否为周期性波束，确定RRC消息中第一预设参数的取值，之后根据待配置的波束的起始位置，确定RRC消息中第二预设参数的取值，最后向智能中继发送用于配置service link对应的波束的信息的RRC消息。由此，智能中继可以根据波束的周期及起始位置，实现智能中继类似网络设备的波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。
请参见图10，下面以半静态波束循环、及半静态固定波束指示场景为例，对本公开提供的智能中继服务链路的波束指示方法进行说明。图10是本公开实施例提供的一种智能中继服务链路的波束指示方法的流程示意图,该方法由网络设备执行。如图10所示，该方法可以包括但不限于如下步骤：
步骤101，向智能中继发送无线资源控制RRC消息，其中，RRC消息用于为智能中继配置服务链路service link对应的波束的信息。
其中，步骤101的具体实现形式，可参照本公开其他各实施例中的详细描述，此处不再详细赘述。
步骤102，向智能中继发送第一指示信息，其中，第一指示信息用于触发或激活RRC消息配置的波束中的至少一个波束。
可以理解的是，对于半静态波束循环、及半静态固定波束指示而言，RRC消息配置的波束信息中不包含每个波束对应的起始时间，因此，网络设备可以通过第一指示信息，对RRC消息配置的波束中的至少一个波束进行激活或触发，进而使智能中继可以向终端设备发送被激活或触发的波束，以保证与终端设备的通信。
可选的，第一指示信息中可以包括以下至少一项：
波束配置的标识；
多组波束的标识；
一组波束的标识；

可选的，网络设备可以通过DCI向智能中继发送第一指示信息，也可以通过MACCE向智能中继发送第一指示信息，本公开对此不做限定。
可选的，在智能中继为网络设备的情况下，智能中继可以通过下行控制信息DCI接收第一指示信息。
或者，在智能中继为具有中继功能的终端设备的情况下，智能中继可以通过媒体接入控制MAC控制单元CE接收第一指示信息。
可以理解的是，在智能中继为网络单元的情况下，由于网络单元中不存在数据的传输，不需要指示传输数据所使用的域，所以DCI的开销较小。因此，网络设备通过DCI触发RRC消息配置的波束中的至少一个波束，可以节省资源，提高波束配置的效率。
而在智能中继为具有中继功能的终端设备的情况下，具有中继功能的终端设备中可能存在数据的传输，若用DCI指示RRC消息配置的波束中的至少一个波束，不能准确地确定波束是否激活，还会增加DCI的开销。但是，MACCE具有良好的扩展性，且MACCE有与之对应的确认信令，可以确认波束是否激活，因此，网络设备通过MAC CE激活RRC消息配置的波束中的至少一个波束，可以保证信息的可靠传 输。
本公开实施例中，网络设备先向智能中继发送用于配置service link对应的波束的信息的RRC消息，之后向智能中继发送用于触发或激活RRC消息配置的波束中的至少一个波束的第一指示信息。由此，智能中继在接收网络设备发送的触发或激活RRC消息配置的波束中的至少一个波束的第一指示信息后，即可基于第一指示信息激活或触发的至少一个波束与终端设备进行通信，从而实现智能中继类似网络设备的波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。
请参见图11，下面以动态波束循环、或动态波束指示场景为例，对本公开提供的智能中继服务链路的波束指示方法进行说明。图11是本公开实施例提供的一种智能中继服务链路的波束指示方法的流程示意图,该方法由网络设备执行。如图11所示，该方法可以包括但不限于如下步骤：

步骤113，向智能中继发送第三指示信息，其中，第三指示信息用于指示第一指示信息触发或激活的至少一个波束中的至少一个波束。
可以理解的是，对于动态波束循环、及动态波束指示，网络设备配置的RRC消息中不包含每个非周期性波束对应的使用时间信息，因此，网络设备需要向智能中继发送第三指示消息对RRC消息配置的波束或通过MAC CE已经激活的至少一个波束中的至少一个波束进行触发，进而智能中继可以向终端设备发送被触发的波束，以保证与终端设备的通信。
可选的，第三指示信息中可以包括以下至少一项：

可选的，网络设备在确定第一数量个时间单元的取值之后，可以将第一数量个时间单元的取值发送给智能中继，以使智能中继根据第一数量个时间单元的取值，确定至少一个波束的起始位置。
可选的，响应于至少一个波束的类型变化，确定第一数量个时间单元的取值大于或等于以下协议约定的至少一项：
信号处理时延；
频域转换时延；
上行定时提前时延；
上行准备时延；

波束切换时延。
本公开中，网络设备可以基于确定的服务链路的起始位置，准确确定智能中继及终端设备的状态，进而根据智能中继及终端设备的状态，对智能中继及终端设备进行业务调度，从而有效避免了调度错误。
本公开实施例中，网络设备先向智能中继发送用于配置service link对应的波束的信息的RRC消息，之后向智能中继发送用于指示RRC配置的波束的类型的第二指示信息，再通过DCI向智能中继发送用于触发RRC消息配置的波束中的至少一个波束的第一指示信息，最后确定至少一个波束的起始位置为发送DCI之后的第一数量个时间单元对应的时域位置。由此，实现智能中继类似网络设备的波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。
请参见图13，图13是本公开实施例提供的一种智能中继服务链路的波束指示方法的流程示意图,该方法由网络设备执行。如图13所示，该方法可以包括但不限于如下步骤：

其中，步骤131至步骤133的具体实现形式，可参照本公开其他各实施例中的详细描述，此处不再详细赘述。
需要说明的是，智能中继使用的波束的类型，可以在网络设备为智能中继配置service link对应的波束的信息时，同时指示，也可以在进行了波束配置后，再单独指示；或者，波束的类型，也可以在利用MAC CE为智能中继激活波束时，同步指示，或者，也可以与MAC CE分开指示，本公开对此不做限定。

本公开实施例中，网络设备先向智能中继发送用于配置service link对应的波束的信息的RRC消息，之后向智能中继发送用于指示RRC配置的波束的类型的第二指示信息，再通过MAC CE向智能中继发送用于触发RRC消息配置的波束中的至少一个波束的第一指示信息，最后确定至少一个波束的起始位置为接收到智能中继发送的确认信令之后的第二数量个时间单元对应的时域位置。由此，实现了智能中继类似网络设备的波束收发要求，不仅保证了智能中继的可靠使用，为扩大服务小区覆盖范围提供了条件，而且保证了信息的可靠传输。
本公开实施例中，对于周期性波束循环而言：
在service link上，比如，用于系统信息广播，周期性参考信号发送，其波束指示可以通过网络设备为smart repeater配置一组或多组周期性波束完成，具体配置参数至少包括一组波束ID，周期以及波束的起始位置；波束ID可以通过一个参考信号ID指示，该参考信号可以QCL到某个已有的参考信号ID。网络设备可以通过RRC信令为智能中继配置service link对应的波束的信息。即向智能中继发送RRC消息，其中，RRC消息用于为智能中继配置服务链路service link对应的波束的信息。波束的信息，至少包含一组波束的标识，周期以及起始位置。

本公开实施例中，对于动态波束循环而言：
在service link上，比如，用于发送非周期信道状态信息参考信号(Channel State InformationResource Config，CSI-RS)(波束循环)，其波束指示可以为网络设备先通过RRC消息为smart repeater配置一组或多组波束，或者通过MAC CE发送的第一指示信息激活的至少一个波束，之后向smart repeater发送第三指示信息，以指示MAC CE激活的至少一个波束中的至少一个波束。网络设备可以通过DCI向smart repeater发送第三指示信息。smart repeater收到第三指示信息后，根据第三指示信息指示的波束信息，发送相应的波束。

本公开实施例中，为了满足不同类型波束配置的一致性，可以通过将周期设为NULL的方式表示没有周期，将起始位置相关参数设置为NULL的方式表示没有起始位置，由此，可以将RRC消息的beam configuration统一化。
本公开实施例中，RRC配置中每个波束持续使用的时间，默认是一个时间单元，比如一个时隙slot或，一个符号symbol，smart repeater根据波束ID出现的顺序依次使用波束；也可以在RRC消息中对周期进行指示。如果指示了周期，smart repeater按照指定的周期依次使用波束。可选的，如果网络设备仅为smart repeater配置了一组beam configuration，那么beam configuration ID可省略。
可选的，在RRC配置中，还可以进一步增加波束的时间特性，如，周期性波束、半静态波束或非周期性波束，来指示波束的时间特性，进而指示smart repeater使用波束的行为。
