Abstract

Disclosed are a method and device for scheduling and transmission, a terminal, a communication node, and a storage medium. The method comprises: a first communication node acquiring clock information; and sending m types of clock information to a terminal on the basis of the acquired clock information, where m is greater than or equal to 1.

First claim

The invention claimed is:

1. An information transmission method, applied to a first communication node, the method comprising:
acquiring capability information reported by a terminal, the capability information indicating clock related capability supported by the terminal; and
sending m types of clock information to the terminal based on the capability information, m being greater than or equal to 1, wherein the m types of clock information comprise synchronization inaccuracy information indicating an inaccuracy value of reference time information.

2. The method of claim 1 , further comprising: acquiring clock information,
wherein acquiring the clock information comprises at least one of the following:
acquiring the clock information from a core network;
acquiring the clock information from an adjacent communication node;
receiving the clock information sent by the terminal; or
acquiring the clock information from a specific network system.

3. The method of claim 1 , wherein the capability information comprises at least one of the following:
a clock type supported by the terminal; or
at least one of synchronization precision information or synchronization granularity information supported by the terminal.

4. The method of claim 2 , wherein the clock information sent by the terminal comprises:
clock information of a system to which the terminal is being connected.

5. The method of claim 1 , wherein the m types of clock information further comprise at least one of the following:
time information of Universal Time Coordinated (UTC);
an offset between the UTC and Global Positioning System (GPS);
information about a relationship between Daylight Saving Time (DST) and local time;
an offset between the UTC and the local time;
an offset between the UTC and a specific network;
a mapping relationship between the UTC and a System Frame Number (SFN);
indication information about whether a clock corresponding to the m types of clock information is a master clock;
level information of the clock;
information about an offset with respect to a reference time of a specific clock type;
synchronization precision information of the clock;
synchronization granularity information of the clock;
type information of the clock;
the reference time information;
position relationship indication information of the reference time information and a received signaling; or
time update period information of the clock.

6. The method of claim 5 , wherein the reference time information comprises at least one of the following:
reference system radio frame information;
reference subframe information;
reference slot information; or
reference time symbol information.

7. An information transmission method, applied to a terminal, the method comprising:
sending capability information to a first communication node, the capability information indicating clock related capability supported by the terminal; and
receiving m types of clock information sent by the first communication node based on the capability information, m being greater than or equal to 1, wherein the m types of clock information comprise synchronization inaccuracy information indicating an inaccuracy value of reference time information.

8. The method of claim 7 , wherein the capability information comprises at least one of the following:
a clock type supported by the terminal; or
at least one of synchronization precision information or synchronization granularity information supported by the terminal.

9. The method of claim 7 , further comprising: sending clock information to the first communication node, wherein the clock information comprises:
clock information of a system to which the terminal is being connected.

10. The method of claim 7 , wherein the m types of clock information further comprise at least one of the following:
time information of Universal Time Coordinated (UTC);
an offset between the UTC and Global Positioning System (GPS);
information about a relationship between Daylight Saving Time (DST) and local time;
an offset between the UTC and the local time;
an offset between the UTC and a specific network;
a mapping relationship between the UTC and a System Frame Number (SFN);
indication information about whether a clock corresponding to the m types of clock information is a master clock;
level information of the clock;
information about an offset with respect to a reference time of a specific clock type;
synchronization precision information of the clock;
synchronization granularity information of the clock;
type information of the clock;
the reference time information;
position relationship indication information of the reference time information and a received signaling; or
time update period information of the clock.

11. The method of claim 10 , wherein the reference time information comprises at least one of the following:
reference system radio frame information;
reference subframe information;
reference slot information; or
reference time symbol information.

12. A communication node, comprising: a second communication interface, configured to implement the method of claim 1 .

13. The communication node of claim 12 , wherein the second communication interface is configured to acquire clock information through at least one of the following:
