Communication method, terminal, network device, and storage medium

A network device, comprising:

• at least one processor coupled to a communication interface;
• the communication interface coupled to one or more memories;
• and
• the one or more memories coupled to the at least one processor and storing computer-readable instructions for execution by the at least one processor to cause the network device to perform operations comprising:
• sending, through the communication interface, a first message, wherein the first message includes target adjustment information;
• sending, through the communication interface, a second message, wherein the second message includes a timing advance (TA), the target adjustment information is used to determine a delay time, and the TA is used to determine a first uplink sending time;
• and
• receiving, through the communication interface, an uplink transmission sent at an uplink sending time, wherein the uplink sending time is the first uplink sending time delayed by the delay time;
• wherein the operations further comprise:
• receiving, through the communication interface, a message msg3 from a terminal device, wherein the message msg3 triggers a start of a first timer after a preset duration, wherein the first timer is used to monitor a contention resolution message msg4.

A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by at least one processor, cause a communication apparatus to perform operation comprising:

• sending a first message, wherein the first message includes target adjustment information;
• sending a second message, wherein the second message includes a timing advance (TA), the target adjustment information is used to determine a delay time, and the TA is used to determine a first uplink sending time;
• and
• receiving an uplink transmission sent at an uplink sending time, wherein the uplink sending time is the first uplink sending time delayed by the delay time;
• wherein the operations further comprise:
• receiving a message msg3 from a terminal device, wherein the message msg3 triggers a start of a first timer after a preset duration, wherein the first timer is used to monitor a contention resolution message msg4.
