Title
(EN) Channel detection method and apparatus
(ZH) 信道检测方法及装置
Abstract
(EN)
The present disclosure provides a channel detection method and an apparatus. The method is used for a base station operating on an unlicensed frequency band. The method comprises the steps that it isdetected thatt the first uplink transmission is not successfully transmitted; a target channel detection mechanism for conducting channel detection on a first downlink transmission is determined, andthe first downlink transmission is used to represent a next downlink transmission after the first uplink transmission; the first downlink transmission is subjected to channel detection according to the target channel detection mechanism. Accordingly, the present disclosure can specifically select which channel detection mechanism to use according to actual conditions, thereby improving the accuracy and efficiency of channel detection.
