For example, after the first terminal sends SL DRX configuration assistance information and/or SL DRX configuration rejection information to the second terminal, if the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, for example, the second terminal does not If the second condition is met, the second terminal will not send updated SL DRX configuration information, and the default transmission state between the first terminal and the second terminal is the SL DRX sleep state (SL DRX off), or the first terminal and the second terminal The transmission between the two terminals is in a non-SL DRX state, that is, the first terminal and the second terminal exit the SL DRX process to save terminal energy consumption.

Alternatively, when the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, the first terminal may also take effect on the SL RB configuration information sent by the second terminal.

Or, when the first terminal does not receive the updated SL DRX configuration information sent by the second terminal, the transmission state between the first terminal and the second terminal is the SL DRX sleep state, and the first terminal takes effect and the second terminal sends SL RB configuration information.
