除非特别说明，否则，本公开中的“第一”“第二”等描述用来区分不同的对象，并不用来表示大小或时序等含义。
在本公开实施例中，网络侧向RIS等网络节点设备传输波束指示信息作为转发波束的控制信息，网络节点设备解码获得网络侧配置的波束指示信息，根据所述波束指示信息调整转发波束或进入节能模式，使得RIS等网络节点设备可以准确地形成相应转发波束图样，更有效地辅助信号传输。

所述无波束，用于指示网络侧此时不需要网络节点设备转发数据，网络节点设备可以在无波束的时隙进入节能模式，或者，网络节点设备在无波束的时隙将转发波束确定或调整为默认波束。
所述波束信息对应的时隙类型为上行时隙或下行时隙。当波束信息对应的时隙为下行时隙时，指示网络节点设备转发从网络侧到用户终端的信息时，所采用的下行波束；当波束信息对应的时隙为上行时隙时，指示网络节点设备转发从用户终端到网络 侧的信息时，所采用的上行波束。因此，如果波束信息对应的时隙类型不同，即使采用相同的波束指示信息，如采用相同的波束索引号，也表征不同的波束指示。
所述各组波束配置信息在时域上不存在交叠部分。
如果一个系统帧内存在未配置波束信息的时隙，则所述时隙相应的波束信息默认为无波束。
所述周期配置，用于指示在相应系统帧上重复波束配置信息的周期，从而周期地在相应系统帧上重复波束配置信息。例如，“波束指示信息”指示的系统帧号为5，“周期配置”为5个系统帧，则在系统帧10,15,20,…，重复系统帧号为5的波束配置信息。
图3示出本公开一些实施例的波束指示信息的示意图。
如图3所示，系统帧号(SFN)为10，且一个系统帧包含10个时隙(0，1，2，…，9)，波束配置信息共3组：第一组波束配置信息起始时隙号为1，持续时隙数为2，波束信息为下行波束2；第二组波束配置信息起始时隙号为5，持续时隙数为2，波束信息为下行波束3；第三组波束配置信息起始时隙号为8，持续时隙数为2，波束信息为上行波束1。此时，时隙0,3,4,7未配置波束信息，则这些时隙默认配置为无波束。
图4示出本公开另一些实施例的波束指示信息的示意图。
如图4所示，系统帧号(SFN)为15，且一个系统帧包含10个时隙(0，1，2，…，9)，波束配置信息共3组，且仅配置了持续时隙数与波束信息，则此时，默认从该系统帧的第一个时隙开始配置波束信息，且下一组波束配置信息从上一组结束时隙的下一时隙开始配置。第一组波束配置信息持续时隙数为5，包括时隙0至时隙4，波束信息为无波束；第二组波束配置信息持续时隙数为2，包括时隙5和时隙6，波束信息为下行波束3；第三组波束配置信息持续时隙数为3，包括时隙7至时隙9，波束信息为无波束。
在步骤220，网络节点设备根据所述波束指示信息，确定或调整转发波束或进入节能模式。

网络节点设备根据所述波束指示信息中的所述波束配置信息中的所述波束信息，确定或调整转发波束或进入节能模式。
如果所述波束信息为波束索引号时，网络节点设备根据所述波束信息对应的时隙类型以及所述波束索引号，确定转发波束。
例如，如果所述波束信息对应的时隙为下行时隙，网络节点设备确定转发波束为：转发从网络侧到用户设备的信息时采用的所述波束索引号相应的下行波束；或者，如果所述波束信息对应的时隙为上行时隙，网络节点设备确定转发波束为：转发从用户设备到网络侧信息时采用的所述波束索引号相应的上行波束。
如果所述波束信息为参考信号信息时，网络节点设备根据所述参考信号信息(如参考信号名称、参考信号索引号等)确定相应的参考信号，确定或调整当前转发波束为先前转发所述参考信号时采用的波束。
如果所述波束信息为无波束时，网络节点设备在所述波束信息相应时隙进入节能模式；或者，
如果所述波束信息为无波束时，网络节点设备将转发波束确定或调整为默认波束。
在本公开实施例中，网络侧向RIS等网络节点设备传输波束指示信息作为转发波束的控制信息，网络节点设备解码获得网络侧配置的波束指示信息，根据所述波束指示信息确定或调整转发波束或进入节能模式，使得RIS等网络节点设备可以准确地形成相应转发波束图样，更有效地辅助信号传输。
