S201、终端设备获取通信参数。
其中，通信参数为根据环境参数确定得到的。
环境参数可以为终端设备所在环境的环境参数，也可以为网络设备所在环境的环境参数。由于终端设备和网络设备的距离通常较近，因此，终端设备所在环境的环境参数与网络设备所在环境的环境参数通常相同或者相近。环境参数可以包括如下参数中的至少一种：湿度、压强或者温度。环境参数可以为终端设备采集得到的，或者网络设备采集得到的，还可以为第三方设备采集得到的。其中，湿度指的是空气湿度，用来衡量空气中水(H 2O)的比例。

当通信参数不同时，终端设备根据通信参数与网络设备进行基于太赫兹电磁波的通信的方式也不同，包括如下多种情况：
当通信参数为频段配置信息时，终端设备在与网络设备进行基于太赫兹 电磁波进行通信的过程中，终端设备使用该频段配置信息所指示的频段所对应的频域资源向网络设备发送数据。
当通信参数为第一指示信息时，若第一指示信息指示终端设备进行CSI反馈，则终端设备在与网络设备进行基于太赫兹电磁波进行通信的过程中，终端设备向网络设备发送信道状态。若第一指示信息指示终端设备不进行CSI反馈，则终端设备在与网络设备进行基于太赫兹电磁波进行通信的过程中，终端设备不向网络设备发送信道状态。

在图2所示的实施例中，在终端设备和网络设备进行基于太赫兹电磁波进行通信的过程中，终端设备可以获取通信参数，并根据通信参数进行基于太赫兹电磁波的通信。该通信参数为根据环境参数确定得到的，使得通信参数与环境参数匹配，这样，可以减少由于大气对太赫兹电磁波的阻碍作用对通信性能带来的影响，进而提高基于太赫兹电磁波的通信性能。
当通信参数不同时，终端设备获取通信参数、以及根据通信参数与网络设备进行基于太赫兹电磁波进行通信的过程可能不同。下面，分别对不同通信参数下，终端设备获取通信参数、以及根据通信参数与网络设备进行基于太赫兹电磁波进行通信的过程进行说明，可以包括如下五种情况：
第一种情况：通信参数为频段配置信息。
当通信参数为频段配置信息时，终端设备可以通过如下两种方式获取频段配置信息：
方式1、网络设备确定频段，并向终端设备发送频段配置信息，频段配置 信息包括该频段。
网络设备可以预先存储不同环境参数下，频率与太赫兹电磁波的分子吸收强度之间的曲线，并根据环境参数和该曲线确定频段。其中，太赫兹电磁波的分子吸收强度可以表示太赫兹电磁波的衰减程度，分子吸收强度越大，衰减程度越大。例如，可以根据环境参数选择对应的曲线，并根据曲线，选择分子吸收强度较小的频段。
下面，结合图3A-图3B，介绍湿度与太赫兹电磁波的分子吸收强度之间的曲线。
图3A为本申请实施例提供的一种曲线示意图。请参见图3A，横轴表示频率，单位为赫兹，横轴中的各频率为N*10 12赫兹，N为横轴上的数字。纵轴表示分子吸收强度。图3A中所示的曲线为湿度为100％时，频率与分子吸收强度之间的曲线。
图3B为本申请实施例提供的另一种曲线示意图。请参见图3B，横轴表示频率，单位为赫兹，横轴中的各频率为N*10 12赫兹，N为横轴上的数字。纵轴表示分子吸收强度。图3B中所示的曲线为湿度为10％时，频率与分子吸收强度之间的曲线。
请参见图3A和图3B，当湿度不同时，频率与分子吸收强度之间的曲线不同。
例如，当环境参数为压强时，还可以根据如下公式确定分子吸收所处的频点
Figure PCTCN2021123998-appb-000001
在进行频段选择时，选择的频段中可以考虑避开该频点

其中，
Figure PCTCN2021123998-appb-000004
为谐振的零压强对应的频点，δ i,g为线性压强偏移量，P 0为预设压强。
网络设备可以向终端设备发送第一信息，第一信息中包括网络设备确定得到的频段配置信息。第一消息包括如下至少一种：RRC信令、媒体接入控制单元(media access control-control element，MAC CE)、下行控制信息(downlink control information，DCI)。
方式2、终端设备确定频段，并向网络设备发送包括该频段的请求消息，网络设备根据请求消息为终端设备确定频段配置信息，并向终端设备发送该频段配置信息，频段配置信息中包括该频段。其中，请求消息用于请求网络 设备根据频段为终端设备确定频段配置信息。
可以通过如下至少一种承载请求消息：PUCCH、PUSCH、MAC-CE、RRC信令。
需要说明的是，终端设备确定频段的过程可以参见网络设备确定频段的过程，此处不再进行赘述。网络设备向终端设备发送频段配置信息的方式可以参见方式1，此次不再进行赘述。
在该种情况下，终端设备获取得到频段配置信息之后，终端设备可以使用频段配置信息所指示的频域资源向网络设备发送上行数据。频段配置信息所指示的频域资源为大气对太赫兹电磁波的阻碍作用较小的频域资源，因此，若终端设备使用该频域资源向网络设备发送上行数据，可以提高上行数据发送的成功率，进而提高基于太赫兹电磁波的通信性能。
第二种情况：通信参数为第一指示信息。
第一指示信息用于指示终端设备是否进行CSI反馈。
当通信参数为第一指示信息时，终端设备可以通过如下两种方式获取第一指示信息：
方式1、终端设备确定第一指示信息。
可以设置环境参数对应的阈值，当环境参数与阈值之间的关系满足预设关系时，确定第一指示信息用于指示进行CSI反馈，否则，确定第一指示信息用于指示不进行CSI反馈。
下面，以环境参数为湿度为例进行说明。
终端设备可以获取湿度对应的第一阈值，终端设备判断湿度是否大于或等于第一阈值，若是，则确定进行CSI反馈，即，第一指示信息指示终端设备进行CSI反馈，若否，则确定不进行CSI反馈，即，第一指示信息指示终端设备不进行CSI反馈。
终端设备可以通过网络设备的高层信令配置或者预定义的方式获取第一阈值。
例如，假设终端设备判断湿度大于或等于第一阈值，则将第一指示信息设置为1，该数值1用于指示终端设备进行CSI反馈。假设终端设备判断湿度小于第一阈值，则将第一指示信息设置为0，该数值0用于指示终端设备不进行CSI反馈。
在湿度大于或等于第一阈值时，由于大气对太赫兹电磁波的阻碍作用较 大，可能导致CSI反馈失败，因此，终端设备可以进行CSI重传。CSI重传次数与湿度具有对应关系，CSI重传次数与湿度可以为正相关，即，湿度越大，重传次数越大。例如，CSI重传次数与湿度之间的对应关系可以如表1所示：
表1
湿度 CSI重传次数2
0％-20％ 2
21％-40％ 4
41％-60％ 6
61％-80％ 8
81％-100％ 10
CSI重传次数与湿度之间的对应关系可以网络设备通过高层参数配置的，也可以为预定义的。
方式2、网络设备确定第一指示信息，并向终端设备发送第一指示信息。
需要说明的是，网络设备确定第一指示信息的过程可以参见方式1中终端设备确定第一指示信息的过程，此处不再进行赘述。
网络设备可以向终端设备发送第一信息，第一信息中包括网络设备确定得到的第一指示信息。第一消息包括如下至少一种：RRC信令、MAC CE、DCI。
在该种情况下，终端设备获取得到第一指示信息之后，终端设备可以根据第一指示信息确定是否进行CSI反馈。
若第一指示信息指示终端设备不进行CSI反馈，则终端设备不向网络设备发送信道状态。
若第一指示信息指示终端设备进行CSI反馈，则终端设备向网络设备发送信道状态，例如，终端设备可以周期性的向网络设备发送信道状态，或者，终端设备可以在预定的时刻向网络设备发送信道状态。网络设备接收到信道状态之后，可以根据信道状态调整终端设备的通信参数(重传次数、频段等信息)。终端设备通过进行CSI反馈，可以使得网络设备及时调整终端设备的通信参数，使得调整后的通信参数与环境参数更加匹配，以减少由于大气对太赫兹电磁波的阻碍作用对通信性能带来的影响，进而提高基于太赫兹电磁波的通信性能。进一步的，终端设备只在必要的情况下进行CSI反馈，使 得信令开销较小。
第三种情况：通信参数为发射功率。
发射功率可以为实际发射功率或者最大发射功率。
当通信参数为发射功率时，终端设备可以通过如下两种方式获取发射功率：
方式1、终端设备确定发射功率。
可以设置环境参数与发射功率之间的对应关系，终端设备可以根据环境参数和该对应关系确定发射功率。
下面，以环境参数为湿度为例进行说明。
当环境参数为湿度时，可以获取湿度与发射功率之间的第二对应关系，并根据湿度和第二对应关系，确定终端设备的发射功率。第二对应关系可以包括多个湿度区间和每个湿度区间对应的发射功率。第二对应关系可以网络设备通过高层参数配置的，也可以为预定义的。
例如，第二对应关系可以如表2所示：
表2
湿度 发射功率
0％-20％ A
21％-40％ B
41％-60％ C
61％-80％ D
81％-100％ E
或者，第二对应关系可以如表3所示：
表3
湿度 发射功率
0％-20％ A
21％-40％ A+偏移量1
41％-60％ A+偏移量2
61％-80％ A+偏移量3
81％-100％ A+偏移量4
或者，第二对应关系可以如表4所示：
表4
湿度 发射功率
0％-20％ A
21％-40％ A+权重1*偏移量
41％-60％ A+权重2*偏移量
61％-80％ A+权重3*偏移量
81％-100％ A+权重4*偏移量
需要说明的是，上述表2-表4只是以示例的形式示意第二对应关系，并非对第二对应关系进行的限定。
方式2、网络设备确定发射功率，并向终端设备发送发射功率。
需要说明的是，网络设备确定发射功率的过程可以参见方式1中终端设备确定发射功率的过程，此处不再进行赘述。
网络设备可以向终端设备发送第一信息，第一信息中包括网络设备确定得到的发射功率。第一消息包括如下至少一种：RRC信令、MAC CE、DCI。
在该种情况下，终端设备获取得到发射功率之后，终端设备按照该发射功率向网络设备发送上行数据。该发射功率与环境参数相匹配，终端设备按照该发射功率发送上行数据，不但可以避免过大的发射功率导致浪费能耗，还可以使得终端设备发送上行数据的成功率较高，以提高基于太赫兹电磁波的通信。
第四种情况：通信参数为上行重传次数。
当通信参数为上行重传次数时，终端设备可以通过如下两种方式获取上行重传次数。
方式1、终端设备确定上行重传次数。
可以设置环境参数与上行重传次数之间的对应关系，终端设备可以根据环境参数和该对应关系确定发射功率。
下面，以环境参数为湿度为例进行说明。
当环境参数为湿度时，可以获取湿度与上行重传次数之间的第一对应关系，并根据湿度和第一对应关系，确定终端设备的上行重传次数。第一对应关系可以包括多个湿度区间和每个湿度区间对应的上行重传次数。
例如，第一对应关系可以如表5所示：
表5
湿度 上行重传次数
0％-20％ 2
21％-40％ 4
41％-60％ 6
61％-80％ 8
81％-100％ 10
第一对应关系可以网络设备通过高层参数配置的，也可以为预定义的。
方式2、网络设备确定上行重传次数，并向终端设备发送上行重传次数。
需要说明的是，网络设备确定上行重传次数的过程可以参见方式1中终端设备确定上行重传次数的过程，此处不再进行赘述。
网络设备可以向终端设备发送第一信息，第一信息中包括网络设备确定得到的上行重传次数。第一消息包括如下至少一种：RRC信令、MAC CE、DCI。
在该种情况下，终端设备获取得到上行重传次数之后，终端设备按照该上行重传次数向网络设备发送上行数据。该上行重传次数与环境参数相匹配，终端设备按照该上行重传次数发送上行数据，可以提高终端设备发送上行数据的成功率，进而提高基于太赫兹电磁波的通信。
第五种情况、通信参数为第二指示信息。
第二指示信息用于指示终端设备是否进入RLF或者进行BFR流程。
当通信参数为第二指示信息时，终端设备可以通过如下两种方式获取第二指示信息：
方式1、终端设备确定第二指示信息。
可以设置环境参数对应的阈值，当环境参数与阈值之间的关系满足预设关系时，确定第二指示信息用于指示进入RLF或者进行BFR流程，否则，确定第二指示信息用于指示进入RLF或者进行BFR流程。
下面，以环境参数为湿度为例进行说明。
终端设备可以获取湿度对应的第二阈值，终端设备判断湿度是否大于或等于第二阈值，若是，则确定进入RLF或者进行BFR流程，即，第二指示信息指示终端设备进入RLF或者进行BFR流程，若否，则确定不进入RLF或 者不进行BFR流程，即，第二指示信息指示终端设备不进入RLF或者不进行BFR流程。
终端设备可以通过网络设备的高层信令配置或者预定义的方式获取第二阈值。
