1. A method for receiving a target downlink signal, applied to uplink transmission and downlink transmission using an unlicensed band, and comprising:
waiting by a terminal for receiving a target downlink signal within a first window;
launching a second window by the terminal when the terminal receives an indication of having obtained channel sent by an access network device within the first window, wherein the indication of having obtained channel is a signal other than physical downlink control channel (PDCCH) scheduling information, and the indication of having obtained channel indicates that the access network device successfully occupies the unlicensed band within the first window;
waiting by the terminal for receiving the target downlink signal within the second window; and
when the first window ends, performing one of initiating connection reestablishment, reporting a radio link failure (RLF), or re-initiating a random access procedure by the terminal.
