Wireless communication methods and terminal devices
By introducing indication information and feedback mechanisms into the side link system, the consistency of the sender's and receiver's understanding of the receiver's state is ensured, thus solving the transmission reliability problem caused by inconsistent state understanding and achieving more reliable data transmission.

AI Technical Summary
Technical Problem
In a sidelink system, the sending terminal and the receiving terminal have inconsistent understandings of the receiving terminal's state, leading to reliability issues in sidelink data transmission.
Method used
The first terminal detects the indication information sent by the second terminal, determines the target status, and sends side-line feedback information to ensure whether the first terminal starts a timer or receives data within a specific time range. The second terminal determines whether to send side-line data based on the feedback information.
Benefits of technology
This avoids side-by-side data transmission failures caused by inconsistent state understanding, thus improving transmission reliability.

Abstract
Wireless communication methods and terminal devices. A method comprises: a first terminal detects first instruction information sent by a second terminal, the first instruction information being used for instructing the first terminal to enter a target state, the target state being used for instructing the first terminal whether to start a first timer, or the target state being used for instructing the first terminal whether to receive sidelink data within a first time range, the first timer being related to a sidelink discontinuous reception duration timer, and the first time range being determined on the basis of the first timer; and the first terminal sends sidelink feedback information of the first instruction information to the second terminal.
