Abstract

This application provides a measurement method and an apparatus. In the measurement method, a communications apparatus may receive configuration information, where the configuration information includes a cell list and indication information, and the indication information is used to indicate whether a measurement event is affected by the cell list; and the communications apparatus performs a measurement evaluation based on the cell list and the indication information. In this implementation, whether to perform a trigger evaluation for a measurement result of a cell in the cell list may be determined depending on whether the measurement event is affected by the cell list, to avoid an unnecessary trigger evaluation for a cell.

First claim

What is claimed is:

1. A communication method, comprising:
sending, by a first base station, a first message to a second base station; and
receiving, by the first base station in response to sending the first message, a second message from the second base station, wherein the second message comprises:
a cell list including information on cells included by the second base station; and
information about whether each cell in the cell list is a non-independent cell, wherein a physical broadcast channel (PBCH) of a synchronization signal block (SSB) of the non-independent cell does not carry location information of system information block 1 (SIB 1), and the non-independent cell is a cell in which no SIB 1 is sent.

2. The method according to claim 1 , wherein the method further comprises:
sending, by the first base station, a third message to a terminal device, wherein the third message requests a cell global identifier of a first cell, and the third message includes a first frequency of the first cell and a first physical cell identifier (PCI) indicating the first cell; and
wherein the second base station is a target network device indicated by the cell global identifier of the first cell.

3. The method according to claim 2 , wherein the method further comprises:
receiving, by the first base station, a fourth message in response to the third message, wherein the fourth message includes the cell global identifier of the first cell.

4. The method according to claim 1 , wherein the cell list comprise a first non-independent cell; and
wherein the first non-independent cell is a cell in which no system information is sent or a cell in which a part of system information is sent; or
or
wherein the first non-independent cell is not capable of working as a primary component carrier.

5. The method according to claim 1 , wherein the information about whether each cell in the cell list is the non-independent cell comprises:
information about whether each cell in the cell list is the non-independent cell or an independent cell.

6. The method of claim 1 , wherein the second message further comprises:
a frequency of each cell in the cell list;
a physical cell identifier of each cell in the cell list;
a cell global identifier of each cell in the cell list; or
a cell in the cell list that does not send cell system information.

7. The method according to claim 1 , wherein the PBCH of the SSB of the non-independent cell carries location information of an SSB of another cell different from the non-independent cell.

8. A communication method, comprising:
receiving, by a second base station, a first message from a first base station; and
sending, by the second base station in response to receiving the first message, a second message to the first base station, wherein the second message comprises:
a cell list including information on cells included by the second base station; and
information about whether each cell in the cell list is a non-independent cell, wherein a physical broadcast channel (PBCH) of a synchronization signal block (SSB) of the non-independent cell does not carry location information of system information block 1 (SIB 1), and the non-independent cell is a cell in which no SIB 1 is sent.

9. The method according to claim 8 , wherein the cell list comprise a first non-independent cell; and
wherein the first non-independent cell is a cell in which no system information is sent or a part of system information is sent; or
wherein the first non-independent cell is not capable of working as a primary component carrier.

10. The method according to claim 8 , wherein the information about whether each cell in the cell list is the non-independent cell comprises:
information about whether each cell in the cell list is the non-independent cell or an independent cell.

11. The method of claim 8 , wherein the second message further comprises:
a frequency of each cell in the cell list;
a physical cell identifier of each cell in the cell list;
a cell global identifier of each cell in the cell list; or
a cell in the cell list that does not send cell system information.

12. The method according to claim 8 , wherein the PBCH of the SSB of the non-independent cell carries location information of an SSB of another cell different from the non-independent cell.

13. An apparatus, comprising: one or more processors, and a non-transitory computer-readable storage medium storing program instructions; wherein, when executed by the one or more processors, the instructions cause the apparatus to perform:
sending a first message to a second base station; and
receiving, in response to sending the first message, a second message from the second base station, wherein the second message comprises:
a cell list including information on cells included by the second base station; and
information about whether each cell in the cell list is a non-independent cell, wherein a physical broadcast channel (PBCH) of a synchronization signal block (SSB) of the non-independent cell does not carry location information of system information block 1 (SIB 1), and the non-independent cell is a cell in which no system information block 1 (SIB 1) is sent.

14. The apparatus according to claim 13 , wherein the instructions further cause the apparatus to:
send a third message to a terminal device, wherein the third message requests a cell global identifier of a first cell, and the third message includes a first frequency of the first cell and a first physical cell identifier (PCI) indicating the first cell; and
wherein the second base station is a target network device indicated by the cell global identifier of the first cell.

15. The apparatus according to claim 14 , wherein the instructions further cause the apparatus to:
receive a fourth message in response to the third message, wherein the fourth message includes the cell global identifier of the first cell.

16. The apparatus according to claim 13 , wherein the cell list comprise a first non-independent cell; and
wherein the first non-independent cell is a cell in which no system information is sent or a cell in which a part of system information is sent; or
wherein the first non-independent cell is not capable of working as a primary component carrier.

17. The apparatus according to claim 13 , wherein the information about whether each cell in the cell list is the non-independent cell comprises:
information about whether each cell in the cell list is the non-independent cell or an independent cell.

18. The apparatus according to claim 13 , wherein the PBCH of the SSB of the non-independent cell carries location information of an SSB of another cell different from the non-independent cell.

19. An apparatus, comprising: one or more processors, and a non-transitory computer-readable storage medium storing program instructions; wherein, when executed by the one or more processors, the instructions cause the apparatus to perform:
receiving a first message from a first base station; and
sending, in response to receiving the first message, a second message to the first base station, wherein the second message comprises:
a cell list including information on cells included by the apparatus; and
information about each cell in the cell list is a non-independent cell, wherein a physical broadcast channel (PBCH) of a synchronization signal block (SSB) of the non-independent cell does not carry location information of system information block 1 (SIB 1), and the non-independent cell is a cell in which
