Abstract

本申请实施例提供了一种通道校正方法，用于对网络区域内的射频装置进行通道校正，该网络区域内的射频装置被划分为至少一个射频装置组，每个射频装置组包括多个射频装置，第一射频装置所在的基站上预设有配置信息，该配置信息用于指示第一射频装置所在的射频装置组内的每个射频装置发送校正信号的资源位置，第一射频装置为网络区域内的任一射频装置，该方法由第一射频装置所在的基站执行，包括：在校正周期内根据所述配置信息控制第一射频装置在第一资源位置上发送第一校正信号，并接收第二射频装置对第一校正信号的第一接收信号，其中第一资源位置为第一射频装置发送校正信号的资源位置，第二射频装置为第一射频装置所在射频装置组内的射频装置；在校正周期内根据配置信息通过第一射频装置在第二资源位置上获取第二校正信号的第二接收信号，其中第二资源位置为第二射频装置发送第二校正信号的资源位置；根据第一校正信号、第二校正信号、第一接收信号和第二接收信号对第一射频装置的通道进行补偿。以上方法可以实现多个射频装置联合的通道校正，提高校正效率。
