1. A sidelink discontinuous transmission (DTX) method, applicable to a second user terminal, the method comprising:
allowing performing data scheduling/transmission to a first user terminal during running of an on duration transmit timer; and
starting, in a case that data scheduling/transmission to the first user terminal is triggered, an inactivity transmit timer to continuously allow performing data scheduling/transmission to the first user terminal,
wherein after the starting, in a case that data scheduling/transmission to the first user terminal is triggered, the inactivity transmit timer to continuously allow performing data scheduling/transmission to the first user terminal, the method further comprises:
restarting the inactivity transmit timer in a case that data scheduling/transmission to the first user terminal is triggered again during running of the inactivity transmit timer,
before allowing performing data scheduling/transmission to the first user terminal during running of the on duration transmit timer; or starting, in a case that data scheduling/transmission to the first user terminal is triggered, the inactivity transmit timer to continuously allow performing data scheduling/transmission to the first user terminal, the method further comprises:
turning off a target receive timer according to a DRX mechanism in a case that it is detected that a target transmit timer and the target receive timer are both running, wherein it is agreed in the DRX mechanism that a send priority of the second user terminal is higher than a send priority of the first user terminal, wherein the target transmit timer is one of the on duration transmit timer, the inactivity transmit timer and the retransmission transmit timer.
