Abstract

The invention discloses a wireless link state judging method and a terminal. The method includes: detecting a target reference signal on a target resource configured by a network device to obtain a detection result; judging whether the wireless link state is based on the detection result of the target reference signal is the undetected target reference signal. The embodiments of the present invention can improve the accuracy of wireless link state judgment, avoid reporting inaccurate wireless link state indication information due to failure to detect target reference signals, thereby ensuring information transmission between network devices and terminals.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for judging the status of a wireless link and a terminal. Background technique [0002] In the fifth generation (5th Generation, 5G) mobile communication system, or called the new air interface (New Radio, NR) system, in the licensed-assisted access (Licensed-Assisted Access, LAA) scenario, or called the unlicensed frequency band In the transmission scenario, since the unlicensed frequency band is shared by multiple technologies, such as wireless routers, radars, and Bluetooth devices, etc., devices working in the unlicensed frequency band need to adopt a distributed coordinated access method based on competition, such as listen first and then talk (Listen first). -Before-Talk, LBT) process. Before sending information, the sending node (base station or terminal) needs to do ClearChannel Access (CCA) / Extended Clear Channel Assessment (eCCA) to listen to th...
