举例来说,图3是不同第二上行资源与传输格式为DL的频域资源单元之间的位置关系示意图。请参考图3,图中以频域资源单元是频域子带为例进行说明。

从图中可以看出,频域子带1与频域子带2被相邻设置,频域子带2与频域子带3被相邻设置,频域子带3与频域子带4被相邻设置。相较于频域子带1与频域子带3之间的频域间隔,频域子带2与频域子带3之间的频域间隔更小,故可以认为频域子带2相较于频域子带1受到更大的邻信道干扰,此时可以设置频域子带2对应一个第二功率控制配置信息,并设置频域子带1对应另一个第二功率控制配置信息,这两个第二功率控制配置信息中可以有部分参数相同,也可以有部分参数不同,例如频域子带2对应的第二功率控制配置信息包括的发射功率,可以大于频域子带1对应的第二功率控制配置信息包括的发射功率。
另外,也可以通过另一种方法比较频域子带1与频域子带2受到的邻信道干扰。图3中频域子带3和频域子带4的中心频点为fDL,频域子带1的 中心频点为fUL,1,频域子带2的中心频点为fUL,2,可见,相较于fUL,1与fDL之间的频域间隔,fUL,2与fDL之间的频域间隔更小,故可以认为频域子带2相较于频域子带1受到更大的邻信道干扰。

当终端需要在频域子带1的PUSCH发送上行数据时,由于频域子带1与距离最近的传输格式为DL的频域子带,即与频域子带3的频域间隔为1个频域子带,故终端根据第一功率控制配置信息确定上行传输的发射功率为P1。
具体地,当终端需要在频域子带1的PUSCH发送上行数据时,由于频域子带1与距离最近的传输格式为DL的频域子带3的频域间隔为1个频域子带,可以认为邻信道干扰的影响较小,终端可以根据第一功率控制配置信息确定上行传输的发射功率,不需要考虑邻信道干扰。
当终端需要在频域子带2的PUSCH发送上行数据时,由于频域子带2与距离最近的传输格式为DL的频域子带,即与频域子带3的频域间隔为0个频域子带,故终端根据第二功率控制配置信息确定上行传输的发射功率为P2。
具体地,当终端需要在频域子带2的PUSCH发送上行数据时,由于频域子带2与距离最近的传输格式为DL的频域子带3相邻,可以认为邻信道干扰的影响较大,终端可以根据第二功率控制配置信息确定上行传输的发射功率,此时需要考虑邻信道干扰。
可选地,设置P2>P1,以通过提高上行信道的发射功率,来提高上行传输的性能。

当终端需要在频域子带2的PUSCH发送上行数据时,终端根据第二功率控制配置A信息确定上行传输的发射功率为P2。
具体地,当终端需要在频域子带2的PUSCH发送上行数据时,由于频域子带2与距离最近的传输格式为DL的频域子带3单侧相邻,可以认为邻信道干扰的影响较大,终端可以根据第二功率控制配置信息A确定上行传输的发射功率,此时需要考虑邻信道干扰。
当终端需要在频域子带5的PUSCH发送上行数据时,终端根据第二功率控制配置信息B确定上行传输的发射功率为P3。
具体地,当终端需要在频域子带5的PUSCH发送上行数据时,由于频域子带5与距离最近的传输格式为DL的频域子带4和频域子带6均相邻,可以认为邻信道干扰的影响更大,终端可以根据第二功率控制配置信息B确定上行传输的发射功率,此时需要考虑邻信道干扰。
