具体而言,网络设备可以向终端设备发送指示信息,该指示信息指示网络设备在多个配置信息中确定的下行传输信道对应的波束,从而网络设备可以在该下行传输信道对应的波束发送该下行传输信道,终端设备获知网络设备发送下行传输信道对应的波束后,可以选择相应的接收波束接收下行传输信道,因此,避免了网络设备的发送波束和终端设备的接收波束不匹配,导致接收性能不好的问题。

所述每个发送波束的标识信息、所述每个发送波束的特有的资源占用的信息、所述每个发送波束在所述每个配置信息对应的波束组中的编号。
该每个发送波束的特有的资源占用的信息可以指示该每个发送波束的临时占用的时域资源的信息和/或频域资源的信息,例如,临时在某一时段,使用第一波束发送测量信号,因此,在这一时段,该第一波束上不能用于传输数据,从而该终端设备可以不在这一时段接收数据。

可选地,所述资源映射的信息包括至少一个数据传输资源映射信息,每个数据传输资源映射信息指示所述至少一个发送波束的能够用于下行传输的资源或者不能用于下行传输的资源。

所述网络设备向所述终端设备发送第一信令,所述第一信令包括第一配置指示信息,所述第一配置指示信息指示所述网络设备使用所述多个配置信息中的第一配置信息发送所述数据信道。
也就是说,该网络设备可以通过向终端设备发送第一信令,通过在该第 一信令中包括第一配置指示信息,来指示该网络设备使用哪个配置信息。对于前述的实施例而言,该网络设备可以通过发送第一信令,通知该终端设备该网络设备使用该第一配置信息发送数据信道,在网络设备没更改该配置前,该终端设备始终认为该网络设备使用该第一配置信息发送数据信道。而该网络设备使用该第一配置信息中的哪个编号对应的发送波束发送该数据信道,可以通过发送PDCCH通知该终端设备。
即,网络设备可以半静态配置该网络设备数据信道对应的发送波束,先通过高层信令预配置使用哪个配置信息中的发送波束,然后通过PDCCH动态指示使用该配置信息中的哪个编号对应的发送波束。
可选地,所述第一信令为无线资源控制(全称:Radio Resource Control,简称:RRC)信令或下行控制信息(全称:Downlink Control Information,简称:DCI)。

具体而言,该网络设备可以通过第二波束组中的波束向终端设备发送PDCCH,通过该PDCCH的第二指示字段包括该指示信息,该指示信息直接指示该终端设备接收该数据信道对应的接收波束,从而该终端设备可以使用该数据信道对应的接收波束接收该数据信道。
例如,该多个配置信息包括两个配置信息,如下:
