Abstract
A method for reporting an uplink timing advance is performed by a terminal device and includes: sending first indication information to a network device. The first indication information is used to indicate the uplink timing advance (TA) of the terminal device to the network device. A network device may perform a method for receiving first indication information sent by a terminal device. The first indication information may include at least one of an open-loop uplink TA corresponding to the terminal device; a first uplink TA corresponding to an entire round trip delay (RTD) compensated by the terminal device; or a second uplink TA corresponding to a specific RTD compensated by the terminal device.

A method for reporting an uplink timing advance, performed by a terminal device and comprising:
- sending first indication information to a network device based on a medium access layer (MAC) control element (CE) when a trigger condition is satisfied, wherein the first indication information is used to indicate the uplink timing advance (TA) of the terminal device to the network device;
- wherein the first indication information comprises a first uplink TA corresponding to an entire round trip delay (RTD) compensated by the terminal device;
- wherein the trigger condition comprises an offset of a currently to-be-reported TA relative to the adjacent previously reported TA reaching a second threshold value.
A method for reporting an uplink timing advance, performed by a network device and comprising:
- receiving first indication information sent by a terminal device based on a medium access layer (MAC) control element (CE) when a trigger condition is satisfied, wherein the first indication information is used to indicate the uplink timing advance (TA) of the terminal device to the network device;
- wherein the first indication information comprises a first uplink TA corresponding to an entire round trip delay (RTD) compensated by the terminal device;
- wherein the trigger condition comprises an offset of a currently to-be-reported TA relative to the adjacent previously reported TA reaching a second threshold value.
A communication device, comprising:
- a processor;
- and
- a memory having stored therein a computer program,
- wherein the processor executes the computer program stored in the memory, to cause the device to send first indication information to a network device based on a medium access layer (MAC) control element (CE) when a trigger condition is satisfied, wherein the first indication information is used to indicate an uplink timing advance (TA) of a terminal device to the network device;
- wherein the first indication information comprises a first uplink TA corresponding to an entire round trip delay (RTD) compensated by the terminal device;
- wherein the trigger condition comprises an offset of a currently to-be-reported TA relative to the adjacent previously reported TA reaching a second threshold value.
