图1是根据本公开的实施例示出的一种波束配置方法的示意流程图。本实施例所示的波束配置方法可以由基站执行，所述基站可以与终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置，所述基站包括但不限于4G、5G、6G等通信系统中的基站。
在一个实施例中，所述基站与终端之间，至少可以通过信号中转设备通信，其中，信号中转设备至少可以将基站发送的信号(例如称作下行信号)传输至终端的作用，也可以将终端发送的信号(例如称作上行信号)传输至基站。
在一个实施例中，信号中转设备包括以下至少之一：智能中继器Smart Repeater、智能超表面RIS(Reconfigurable Intelligent Surface)。
传统的射频中继一般只能起到对射频信号进行接收、射频转换、放大转发的作用，并不能用于反射波束信号，也不能进行波束赋形等操作，对于通信系统的性能造成了限制。
而RIS与传统的射频中继不同，在本公开的实施例，可以将RIS部署在无线传输环境中各类物体的表面，接收并反射波束，有望突破传统无线信道的不可控性，构建智能可编程无线环境，引入未来无线通信的新范式。一方面，RIS可以主动地丰富信道散射条件，增强无线通信系统的复用增益；另一方面，RIS可以在三维空间中实现信号传播方向调控及同相位叠加，增大接收信号强度，提高通信设备之间的传输性能。因此，RIS有很大潜力用于未来无线网络的覆盖增强和容量提升，消除局部覆盖空洞。
智能中继器也与传统的射频中继不同，智能中继不仅可以实现传统中继已有的功能，例如对射频信号进行接收、射频转换、放大转发，还可以接收波束，发射波束，以及进行波束赋形等操作。
如图1所示，所述波束配置方法可以包括以下步骤：
在步骤S101中，接收所述信号中转设备发送的能力信息；
在步骤S102中，根据所述能力信息确定所述信号中转设备在与所述终端通信的链路上支持的参考信号的标识，以及所述参考信号的标识对应的波束的信息；
在步骤S103中，根据所述参考信号的标识和所述波束的信息，在所述参考信号的标识中选择目标参考信号标识配置给所述信号中转设备，以供所述信号中转设备通过所述目标参考信号标识对应的波束在所述链路上通信。
在一个实施例中，基站可以通过信号中转设备与终端通信，在这种情况下，基站到终端存在两条链路，链路一为基站到信号中转设备，链路二为信号中转设备到终端，本公开的实施例主要针对在链路二上的通信进行描述。另外，需要说明的是，基站在通过信号中转设备与终端通信的情况下，也可以同时直接与终端通信，本公开并不限制基站与终端的通信方式。
在一个实施例中，不同信号中转设备的能力可以有所不同，例如信号中转设备在与终端通信的链路上，支持的参考信号的标识，以及参考信号的标识对应的波束的信息可以有所不同。所述参考信号的标识包括以下至少之一：同步信号块索引SSB(Synchronization Signal and PBCH block)index、信道状态信息参考信号CSI-RS(Channel State Information-Reference Signal)端口号。
例如有的信号中转设备支持参考信号的标识为SSB index 1至64，有的信号中转设备支持参考信号的标识为CSI-RS端口1至32。
而且由于参考信号的标识与波束之间存在对应关系，支持的参考信号的标识不同，支持的波束的信息也会有所不同的，所述波束信息包括以下至少之一：波束的角度范围、波束对应的频率。以下主要针对波束的角度范围进行示例性说明。
例如有的信号中转设备支持波束的角度范围为0°至180°，有的信号中转设备支持波束的角度范围为0°至270°。其中，上述角度范围的端点和0°对应的方向，可以由基站配置，例如端点可以是信号中转设备所在位置，0°对应的方向可以是信号中转设备指向基站的方向。
信号中转设备通过将能力信息上报给基站，使得基站可以确定信号中转设备在与所述终端通信的链路上支持的参考信号的标识，以及所述参考信号的标识对应的波束的信息。例如确定信号中转设备支持CSI-RS端口1至32，每个CSI-RS端口对应波 束的角度范围为5°，例如CSI-RS端口1对应波束的角度范围为0°至5°，CSI-RS端口2对应波束的角度范围为5°至10°，以此类推，CSI-RS端口32对应波束的角度范围为155°至160°。
进而基站可以根据需要，在信号中转设备支持的参考信号的标识对应的波束中，选择目标参考信号标识对应的波束指示给信号中转设备使用，例如基站根据需要判断只需要信号中转设备在40°至80°的波束角度范围内使用波束通信即可，那么可以确定CSI-RS端口9至CSI-RS端口16为目标参考信号标识配置给信号中转设备。后续信号中转设备可以通过CSI-RS端口9至CSI-RS端口16中一个或多个端口对应的波束进行信号中转设备到终端的链路上的通信。
根据本公开的实施例，基站可以根据信号中转设备的能力信息，配置合适的波束供信号中转设备使用，以进行信号中转设备到终端的链路上的通信。避免信号中转设备使用过多的波束而造成资源浪费，或者使用过少的波束而导致通信质量变差。
图2是根据本公开的实施例示出的另一种波束配置方法的示意流程图。如图2所示，所述根据所述参考信号的标识和所述波束的信息，在所述参考信号的标识中选择目标参考信号标识配置给所述信号中转设备包括：
在步骤S201中，根据所述参考信号的标识和所述波束的信息在所述参考信号的标识中选择目标参考信号标识；
在步骤S202中，设置所述目标参考信号标识对应的序号；
在步骤S203中，将设置的序号配置给所述信号中转设备。
在一个实施例中，基站可以根据需要，在信号中转设备支持的参考信号的标识对应的波束中，选择目标参考信号标识对应的波束指示给信号中转设备使用。
例如信号中转设备支持CSI-RS端口1至32，每个CSI-RS端口对应波束的角度范围为5°，例如CSI-RS端口1对应波束的角度范围为0°至5°，CSI-RS端口2对应波束的角度范围为5°至10°，以此类推，CSI-RS端口32对应波束的角度范围为155°至160°。
而基站根据需要判断只需要信号中转设备在40°至80°的波束角度范围内使用波束通信即可，那么可以确定CSI-RS端口9至CSI-RS端口16为目标参考信号标识。
在确定目标参考信号标识后，由于目标参考信号标识的数量，一般少于所述参考信号的标识的数量，例如本实施例中目标参考信号标识的数量为8个，所述参考信号的标识为32个，因此，可以设置的目标参考信号标识对应的序号，也即对确定所确定的目标参考信号标识重新编号。
例如目标参考信号标识为32个CSI-RS端口中的端口9至16，若通过端口原有的序号进行指示，那么就需要32种指示结果，至少占用5比特，但是实际上目标参考信号标识的数量只是8个，本实施例通过重新编号，可以将CSI-RS端口9至16设置对应序号为1至8，例如序号1(对应比特000)对应端口9、序号2(对应比特001)对应端口10，以此类推，序号8(对应比特111)对应端口16，据此，只需要3比特就能实现对8个标识的指示，有利于节约通信资源。
图3是根据本公开的实施例示出的又一种波束配置方法的示意流程图。如图3所示，所述方法还包括：
在步骤S301中，在通过所述信号中转设备向所述终端发送下行信息时，在所述序号中选择目标参考信号序号；
在步骤S302中，根据所述目标参考信号序号生成传输配置指示TCI(Transmission Configuration Indicator)状态；
在步骤S303中，向所述信号中转设备发送所述TCI状态，用于指示所述信号中转设备通过所述目标参考信号序号对应的波束在所述链路上向所述终端发送所述下行信息。
在一个实施例中，基站在设置所述目标参考信号标识对应的序号，并将设置的序号配置给所述信号中转设备后，可以进一步根据需要在配置给信号中转设备的序号中选择的目标参考信号序号。
由于基站与信号中转设备的位置一般是相对固定的(当然也可以根据需要设置为移动的)，但是终端的位置一般是变化的，所以基站每次通过信号中转设备向终端发送下行信息时，终端可能位置会所有不同，终端可以通过向基站上报自身的位置或上报建议波束对应的参考信号标识，使得基站可以根据终端的位置，确定信号中转设备使用哪个角度的波束向终端发送下行信息更为合适，或者基站根据终端上报的建议波束的参考信号标识确定信号中转设备使用哪个角度的波束向终端发送下行信息。当然，基站除了可以根据终端的位置确定目标参考信号序号，也可以通过考虑其他因素 来确定目标参考信号序号，例如可以根据所发送的下行信息来确定波束对应的目标参考信号序号。
例如基站确定信号中转设备需要使用目标参考信号序号对应的波束向终端发送下行信息，那么可以通过向中转设备发送TCI状态，通过TCI状态来指示目标参考信号序号。例如信号中转设备可以确定所述TCI状态指示的准共址QCL(Quasi co-location)参考信号的标识在所述序号中对应的序号为所述目标参考信号序号，也即信号中转设备确定的目标参考信号序号对应的波束与QCL参考信号波束相同，进而信号中转设备可以通过目标参考信号序号对应的波束在所述链路上向所述终端发送所述下行信息。
在一个实施例中，所述下行信息包括以下至少之一：物理下行控制信道PDCCH(Physical Downlink Control Channel)、物理下行共享信道PDSCH(Physical Downlink Shared CHannel)、解调参考信号DMRS(Demodulation Reference Signal)。基站可以通过信号中转设备向终端发送不同的下行信息，发送不同的下行可以适用于相同的波束，也可以适用不同的波束，具体可以由基站根据需要进行配置。
在一个实施例中，所述向所述信号中转设备发送所述TCI状态包括：半静态地向所述信号中转设备发送所述TCI状态；和/或动态地向所述信号中转设备发送所述TCI状态。
在一个实施例中，基站可以半静态向信号中转设备发送TCI状态。其中，所述半静态地向所述信号中转设备发送所述TCI状态包括：向所述信号中转设备发送所述TCI状态和每个所述TCI状态对应的周期和/或周期内的时段信息。
例如基站可以确定一个或多个TCI状态，以及每个TCI状态对应的周期，比如无线帧，还可以进一步精确到每个TCI状态在周期内对应的时段，比如无线帧中的子帧，进而将TCI状态及其对应的周期和/或周期内的时段信息指示给信号中转设备。
进而信号中转设备可以在TCI状态对应的周期中，或者TCI状态对应周期的时段内判断TCI状态生效，从而使用TCI状态确定上述目标参考信号序号对应的波束，并使用确定的波束向终端发送下行信息。
据此，TCI状态对于信号中转设备是周期性生效的，基站通过配置一次TCI状态，即可实现在后续若干个周期中信号中转设备能够根据TCI状态确定目标参考信号序号对应的波束，而无需在每次发送下行信息时都重新配置TCI状态，有利于节约通 信资源。
在一个实施例中，基站也可以动态地向信号中转设备发送TCI状态。其中，所述动态地向所述信号中转设备发送所述TCI状态包括：通过侧行链路控制信息SCI指示所述下行信息对应的每个时域资源的TCI状态。
例如基站在不同的时域资源，比如时隙，分别通过信号中转设备向终端发送下行信息，那么终端可以通过侧行链路控制信息SCI(Sidelink control information)指示所述下行信息对应的每个时域资源的TCI状态。例如终端每次通过信号中转设备向终端发送下行信息时，可以先向信号中转设备发送SCI，通过SCI指示TCI状态，据此，信号中转设备每次在向终端发送下行信息之前，都可以根据终端发送的SCI确定TCI状态，从而根据TCI状态确定上述目标参考信号序号对应的波束，进而使用确定的波束向终端发送下行信息。
由于基站每次通过信号中转设备向终端发送下行信息时，都通过SCI向信号中转设备指示TCI状态，而TCI状态可以是基站根据实际情况(例如终端的实时位置、当前发送的下行信息)等确定的，有利于确保TCI状态指示的目标参考信号序号对应的波束更符合实际情况，确保良好的通信效果。
图4是根据本公开的实施例示出的一种波束确定方法的示意流程图。本实施例所示的波束确定方法可以由信号中转设备执行，其中，基站与终端之间至少通过所述信号中转设备传输信号。所述基站可以与终端通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等通信装置，所述基站包括但不限于4G、5G、6G等通信系统中的基站。
在一个实施例中，所述基站与终端之间，至少可以通过信号中转设备通信，其中，信号中转设备至少可以将基站发送的信号(例如称作下行信号)传输至终端的作用，也可以将终端发送的信号(例如称作上行信号)传输至基站。

智能中继器也与传统的射频中继不同，智能中继不仅可以实现传统中继已有的功能，例如对射频信号进行接收、射频转换、放大转发，还可以接收波束，发射波束，以及进行波束赋形等操作。
如图4所示，所述波束确定方法可以包括以下步骤：
在步骤S401中，向所述基站发送能力信息，所述能力信息用于指示所述信号中转设备在与所述终端通信的链路上支持的参考信号的标识，以及所述参考信号的标识对应的波束的信息；

在步骤S403中，通过所述目标参考信号标识对应的波束在所述链路上通信。
在一个实施例中，基站可以通过信号中转设备与终端通信，在这种情况下，基站到终端存在两条链路，链路一为基站到信号中转设备，链路二为信号中转设备到终端，本公开的实施例主要针对在链路二上的通信进行描述。另外，需要说明的是，基站在通过信号中转设备与终端通信的情况下，也可以同时直接与终端通信，本公开并不限制基站与终端的通信方式。

例如有的信号中转设备支持参考信号的标识为SSB index 1至64，有的信号中转设备支持参考信号的标识为CSI-RS端口1至32。
而且由于参考信号的标识与波束之间存在对应关系，支持的参考信号的标识不同，支持的波束的信息也会有所不同的，所述波束信息包括以下至少之一：波束的角 度范围、波束对应的频率。以下主要针对波束的角度范围进行示例性说明。
例如有的信号中转设备支持波束的角度范围为0°至180°，有的信号中转设备支持波束的角度范围为0°至270°。其中，上述角度范围的端点和0°对应的方向，可以由基站配置，例如端点可以是信号中转设备所在位置，0°对应的方向可以是信号中转设备指向基站的方向。
信号中转设备通过将能力信息上报给基站，使得基站可以确定信号中转设备在与所述终端通信的链路上支持的参考信号的标识，以及所述参考信号的标识对应的波束的信息。例如确定信号中转设备支持CSI-RS端口1至32，每个CSI-RS端口对应波束的角度范围为5°，例如CSI-RS端口1对应波束的角度范围为0°至5°，CSI-RS端口2对应波束的角度范围为5°至10°，以此类推，CSI-RS端口32对应波束的角度范围为155°至160°。
进而基站可以根据需要，在信号中转设备支持的参考信号的标识对应的波束中，选择目标参考信号标识对应的波束指示给信号中转设备使用，例如基站根据需要判断只需要信号中转设备在40°至80°的波束角度范围内使用波束通信即可，那么可以确定CSI-RS端口9至CSI-RS端口16为目标参考信号标识配置给信号中转设备。后续信号中转设备可以通过CSI-RS端口9至CSI-RS端口16中一个或多个端口对应的波束进行信号中转设备到终端的链路上的通信。
根据本公开的实施例，基站可以根据信号中转设备的能力信息，配置合适的波束供信号中转设备使用，以进行信号中转设备到终端的链路上的通信。避免信号中转设备使用过多的波束而造成资源浪费，或者使用过少的波束而导致通信质量变差。
图5是根据本公开的实施例示出的另一种波束确定方法的示意流程图。如图5所示，所述接收所述基站根据所述参考信号的标识和所述波束的信息，在所述参考信号的标识中选择的目标参考信号标识包括：
在步骤S501中，接收所述基站设置的所述目标参考信号标识对应的序号。
在一个实施例中，基站可以根据需要，在信号中转设备支持的参考信号的标识对应的波束中，选择目标参考信号标识对应的波束指示给信号中转设备使用。
例如信号中转设备支持CSI-RS端口1至32，每个CSI-RS端口对应波束的角度范围为5°，例如CSI-RS端口1对应波束的角度范围为0°至5°，CSI-RS端口2对应波束的角度范围为5°至10°，以此类推，CSI-RS端口32对应波束的角度范围 为155°至160°。
而基站根据需要判断只需要信号中转设备在40°至80°的波束角度范围内使用波束通信即可，那么可以确定CSI-RS端口9至CSI-RS端口16为目标参考信号标识。
在确定目标参考信号标识后，由于目标参考信号标识的数量，一般少于所述参考信号的标识的数量，例如本实施例中目标参考信号标识的数量为8个，所述参考信号的标识为32个，因此，可以设置的目标参考信号标识对应的序号，也即对确定所确定的目标参考信号标识重新编号。

图6是根据本公开的实施例示出的又一种波束确定方法的示意流程图。如图6所示，所述通过所述目标参考信号标识对应的波束在所述链路上通信包括：
在步骤S601中，接收所述基站根据所述序号中的目标参考信号序号生成的传输配置指示TCI状态；
在步骤S602中，确定所述TCI状态指示的准共址QCL参考信号的标识在所述序号中确定所述目标参考信号序号；
在步骤S603中，通过所述目标参考信号序号对应的波束在所述链路上向所述终端发送所述下行信息。
在一个实施例中，基站在设置所述目标参考信号标识对应的序号，并将设置的序号配置给所述信号中转设备后，可以进一步根据需要在配置给信号中转设备的序号中选择的目标参考信号序号。
由于基站与信号中转设备的位置一般是相对固定的(当然也可以根据需要设置为移动的)，但是终端的位置一般是变化的，所以基站每次通过信号中转设备向终端发送下行信息时，终端可能位置会所有不同，终端可以通过向基站上报自身的位置或上报建议波束对应的参考信号标识，使得基站可以根据终端的位置，确定信号中转设 备使用哪个角度的波束向终端发送下行信息更为合适，或者基站根据终端上报的建议波束的参考信号标识确定信号中转设备使用哪个角度的波束向终端发送下行信息。当然，基站除了可以根据终端的位置确定目标参考信号序号，也可以通过考虑其他因素来确定目标参考信号序号，例如可以根据所发送的下行信息来确定波束对应的目标参考信号序号。
例如基站确定信号中转设备需要使用目标参考信号序号对应的波束向终端发送下行信息，那么可以通过向中转设备发送TCI状态，通过TCI状态来指示目标参考信号序号。例如信号中转设备可以确定所述TCI状态指示的准共址QCL参考信号的标识在所述序号中对应的序号为所述目标参考信号序号，也即信号中转设备确定的目标参考信号序号对应的波束与QCL参考信号波束相同，进而信号中转设备可以通过目标参考信号序号对应的波束在所述链路上向所述终端发送所述下行信息。
在一个实施例中，所述下行信息包括以下至少之一：物理下行控制信道PDCCH、物理下行共享信道PDSCH、解调参考信号DMRS。基站可以通过信号中转设备向终端发送不同的下行信息，发送不同的下行可以适用于相同的波束，也可以适用不同的波束，具体可以由基站根据需要进行配置。
在一个实施例中，所述接收所述基站根据所述序号中的目标参考信号序号生成的传输配置指示TCI状态包括：
接收所述基站发送的所述TCI状态和每个所述TCI状态对应的周期和/或周期内的时段信息；
根据所述周期和/或周期内的时段确定对应的TCI状态。
在一个实施例中，基站可以半静态向信号中转设备发送TCI状态。其中，所述半静态地向所述信号中转设备发送所述TCI状态包括：向所述信号中转设备发送所述TCI状态和每个所述TCI状态对应的周期和/或周期内的时段信息。
例如基站可以确定一个或多个TCI状态，以及每个TCI状态对应的周期，例如无线帧，还可以进一步精确到每个TCI状态在周期内对应的时段，例如无线帧中的子帧，进而将TCI状态及其对应的周期和/或周期内的时段信息指示给信号中转设备。
进而信号中转设备可以在TCI状态对应的周期中，或者TCI状态对应周期的时段内判断TCI状态生效，从而使用TCI状态确定上述目标参考信号序号对应的波束，并使用确定的波束向终端发送下行信息。
据此，TCI状态对于信号中转设备是周期性生效的，基站通过配置一次TCI状态，即可实现在后续若干个周期中信号中转设备能够根据TCI状态确定目标参考信号序号对应的波束，而无需在每次发送下行信息时都重新配置TCI状态，有利于节约通信资源。
在一个实施例中，所述接收所述基站根据所述序号中的目标参考信号序号生成的传输配置指示TCI状态包括：
根据所述基站发送的侧行链路控制信息SCI确定所述下行信息对应的每个时域资源的TCI状态。
在一个实施例中，基站也可以动态地向信号中转设备发送TCI状态。其中，所述动态地向所述信号中转设备发送所述TCI状态包括：通过侧行链路控制信息SCI指示所述下行信息对应的每个时域资源的TCI状态。
例如基站在不同的时域资源，例如时隙，分别通过信号中转设备向终端发送下行信息，那么终端可以通过侧行链路控制信息SCI指示所述下行信息对应的每个时域资源的TCI状态。例如终端每次通过信号中转设备向终端发送下行信息时，可以先向信号中转设备发送SCI，通过SCI指示TCI状态，据此，信号中转设备每次在向终端发送下行信息之前，都可以根据终端发送的SCI确定TCI状态，从而根据TCI状态确定上述目标参考信号序号对应的波束，进而使用确定的波束向终端发送下行信息。

图7是根据本公开的实施例示出的又一种波束确定方法的示意流程图。如图7所示，所述方法还包括：
在步骤S701中，基于波束互易性确定所述目标参考信号序号对应的波束对应的上行波束；
在步骤S702中，通过所述上行波束接收所述终端发送的上行信息。
在一个实施例中，信号中转设备在通过目标参考信号序号对应的波束向终端发送下行信息的情况下，后续还可以接收终端发送的上行信息，并将上行信息发送至基站。
而接收终端发送的上行信息，也是需要通过上行波束接收的，而具体通过哪个上行波束进行接收，则可以根据波束互易性确定，例如在同一个方向上，目标参考信号序号对应的波束和上行波束的特性基本一致，那么信号中转设备可以根据目标参考信号序号对应的波束的特性估计上行波束的特性，进而基于上行波束的特性使用上行波束来接收终端发送的上行信息。
