Sidelink DTX method and apparatus, sidelink DRX method and apparatus, and terminal device

A terminal device, comprising a processor, a memory, and a computer program stored on the memory and executable on the processor, wherein the computer program is executed by the processor to execute the following operations:

• 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 processor is configured to:
• restart 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,
• wherein 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 processor is configured to:
• turn off a target receive timer according to a discontinuous reception (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.

A terminal device, comprising a processor, a memory, and a computer program stored on the memory and executable on the processor, wherein the computer program is executed by the processor to execute the following operations:

• monitoring data scheduling/transmission from a second user terminal during running of an on duration monitoring receive timer;
• starting, in a case that the data scheduling/transmission from the second user terminal is received, an inactivity receive timer to continuously monitor the data scheduling/transmission from the second user terminal;
• during running of the inactivity receive timer, in a case that the data scheduling/transmission transmitted by the second user terminal is received again, restarting the inactivity receive timer,
• wherein a target transmit timer is one of the on duration transmit timer, the inactivity transmit timer and a retransmission transmit timer, before monitoring data scheduling/transmission from the second user terminal during running of an on duration monitoring receive timer, the processor is configured to:
• turn off the target transmit timer according to a discontinuous reception (DRX) mechanism in a case that it is detected that the target transmit timer and a 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 a first user terminal.
