Method for transmitting information in random access process, terminal device and network device

A terminal device, comprising:

• a processor and a transceiver,
• the transceiver is configured to:
• if the processor successfully performs listen before talk (LBT), send a first message and indication information to a network device through a target channel occupation time (COT) obtained by the LBT,
• wherein the indication information is used to indicate whether the network device is able to send a second message to the terminal device through the target COT, and the second message is determined by the network device according to the first message.

A network device, comprising:

• a transceiver, configured to receive the first message and indication information sent by a terminal device on a target channel occupation time (COT), wherein the indication information is used to indicate whether the network device is able to use the target COT;
• and
• a processor, configured to determine a second message according to the first message;
• the processor is further configured to:
• determine whether to send the second message to the terminal device through the target COT according to the indication information.
