Abstract

This disclosure provides a method for information transmission, a terminal device, and a network-side device. The method includes: reporting reference time interest information to a network-side device, where the reference time interest information is used to indicate at least one of a reference time of interest to the terminal device and a reference time of no interest to the terminal device.

First claim

What is claimed is:

1 . A method for information transmission, performed by a terminal device and comprising:
reporting reference time interest information to a network-side device; wherein the reference time interest information is used to indicate whether the terminal device is interested in a reference time delivered by the network-side device; the reference time comprises at least one of the following: coordinated universal time (UTC); daylight saving time (DST); global positioning system (GPS) time; or local time; wherein the reporting the reference time interest information to the network-side device comprises: in response to first indication information received from the network-side device indicating that the terminal device is allowed to report the reference time interest information, reporting the reference time interest information to the network-side device, wherein the first indication information is used to indicate whether reporting of the reference time interest information is allowed.

2 . The method according to claim 1 , wherein the reference time interest information comprises at least one of the following:
reference time information of interest; and reference time information of no interest.

3 . The method according to claim 2 , wherein the reference time information comprises at least one of the following:
type of reference time; time precision of reference time; and clock source of reference time.

4 . The method according to claim 1 , wherein a trigger condition for reporting the reference time interest information by the terminal device to the network-side device comprises one of the following:
the terminal device is interested in at least one piece of reference time information; the terminal device is not interested in at least one piece of reference time information; the terminal device has changed interest in at least one piece of reference time information; first content reported by the terminal device has changed, wherein the first content comprises content of reference time information of interest reported by the terminal device or content of reference time information of no interest reported by the terminal device; and the terminal device detects that reference time information received by the terminal device needs to be corrected.

5 . The method according to claim 4 , wherein a determining condition for the terminal device to detect that the reference time information received by the terminal device needs to be corrected comprises one of the following:
a path loss measured by the terminal device is greater than or equal to a first threshold; a path loss variation measured by the terminal device is greater than or equal to a second threshold; an uplink timing advance of the terminal device is greater than or equal to a third threshold; an uplink timing advance variation measured by the terminal device is greater than or equal to a fourth threshold; and indication information received by the terminal device from the network-side device indicates that a cell requires to correct the reference time information.

6 . The method according to claim 1 , wherein after the reporting reference time interest information to a network-side device, the method further comprises:
starting a prohibit timer; wherein before the prohibit timer expires, the terminal device is prohibited from reporting reference time interest information; wherein a parameter of the prohibit timer is predefined by a protocol or configured by a network side.

7 . A method for information transmission, performed by a network-side device and comprising:
receiving reference time interest information reported by a terminal device; wherein the reference time interest information is used to indicate whether the terminal device is interested in a reference time delivered by the network-side device; the reference time comprises at least one of the following: coordinated universal time (UTC); daylight saving time (DST); global positioning system (GPS) time; or local time; wherein the method further comprises: transmitting first indication information to the terminal device, wherein the first indication information is used to indicate whether the terminal device is allowed to report the reference time interest information.

8 . The method according to claim 7 ,
further comprising: configuring a parameter of a prohibit timer for the terminal device.

9 . The method according to claim 7 , wherein the reference time interest information comprises at least one of the following:
reference time information of interest; and reference time information of no interest.

10 . The method according to claim 9 , wherein the reference time information comprises at least one of the following:
type of reference time; time precision of reference time; and clock source of reference time.

11 . The method according to claim 7 , wherein the network-side device is a source node; and
after the receiving reference time interest information reported by a terminal device, the method further comprises: transmitting the reference time interest information to a destination node.

12 . A terminal device, comprising a processor, a memory, and a computer program stored in the memory and capable of running on the processor, wherein when the computer program is executed by the processor, a method for information transmission is implemented, and the method comprises:
reporting reference time interest information to a network-side device; wherein the reference time interest information is used to indicate whether the terminal device is interested in a reference time delivered by the network-side device; the reference time comprises at least one of the following: coordinated universal time (UTC); daylight saving time (DST); global positioning system (GPS) time; or local time; wherein the reporting the reference time interest information to the network-side device comprises: in response to first indication information received from the network-side device indicating that the terminal device is allowed to report the reference time interest information, reporting the reference time interest information to the network-side device, wherein the first indication information is used to indicate whether reporting of the reference time interest information is allowed.

13 . The terminal device according to claim 12 , wherein the reference time interest information comprises at least one of the following:
reference time information of interest; and reference time information of no interest.

14 . The terminal device according to claim 12 , wherein a trigger condition for reporting the reference time interest information by the terminal device to the network-side device comprises one of the following:
the terminal device is interested in at least one piece of reference time information; the terminal device is not interested in at least one piece of reference time information; the terminal device has changed interest in at least one piece of reference time information; first content reported by the terminal device has changed, wherein the first content comprises content of reference time information of interest reported by the terminal device or content of reference time information of no interest reported by the terminal device; and the terminal device detects that reference time information received by the terminal device needs to be corrected.

15 . The terminal device according to claim 12 , wherein after the reporting reference time interest information to a ne
