Abstract

The present invention relates to a measurement reporting method, and a communications apparatus. In the method, measurement reporting parameters reported to a base station satisfies reporting rules including: (a) a reporting setting with a smaller identifier has priority over a reporting setting with a larger identifier; (b) a serving cell with a smaller identifier has priority over a serving cell with a larger identifier; (c) a reporting type involving a beam index indication has priority over a reporting type involving an RI; and (d) aperiodic measurement reporting has priority over semi-persistent measurement reporting, or semi-persistent measurement reporting has priority over periodic measurement reporting. According to the method, performance of a wireless communications system is improved.

First claim

What is claimed is:

1. A measurement reporting method, comprising:
obtaining, by a terminal, values of a plurality of measurement reporting parameters; and
sending, by the terminal a value or values of some of the plurality of measurement reporting parameters to a base station, wherein the some of the plurality of measurement reporting parameters conform to reporting rules, wherein the reporting rules comprise:
a reporting setting with a smaller identifier has priority over a reporting setting with a larger identifier;
a serving cell with a smaller identifier has priority over a serving cell with a larger identifier;
a reporting type involving a beam index indication has priority over a reporting type involving an RI a rank indicator (RI); and
aperiodic measurement reporting has priority over semi-persistent measurement reporting, or semi-persistent measurement reporting has priority over periodic measurement reporting.

2. The method according to claim 1 , wherein the reporting type involving a beam index indication is a reporting type involving a beam index indication and beam quality; and
the some of the plurality of measurement reporting parameters conform to the reporting type involving the beam index indication and beam quality.

3. The method according to claim 2 , wherein the some of the plurality of measurement reporting parameters belong to a first measurement reporting setting, and among the plurality of measurement reporting parameters, a measurement reporting parameter other than the some of the plurality of measurement reporting parameters belongs to a second measurement reporting setting; and
the method further comprises:
weighting and merging, by the terminal, the reporting rules to obtain a priority of the first measurement reporting setting and a priority of the second measurement reporting setting, wherein the first measurement reporting setting has priority over the second measurement reporting setting.

4. The method according to claim 3 , further comprising:
determining that a reporting conflict has occurred, wherein the value or values of some of the plurality of measurement reporting parameters are sent after determining that
a reporting conflict has occurred.

5. A communications apparatus, comprising:
a processor;
a memory comprising a program to be executed in the processor, the processor when the program is executed is configured to perform operations of:
obtaining values of a plurality of measurement reporting parameters; and
sending a value or values of some of the plurality of measurement reporting parameters to a base station, wherein the some of the plurality of measurement reporting parameters conform to reporting rules, wherein the reporting rules comprise:

a reporting setting with a smaller identifier has priority over a reporting setting with a larger identifier;
a serving cell with a smaller identifier has priority over a serving cell with a larger identifier;
a reporting type involving a beam index indication has priority over a reporting type involving a rank indicator (RI); and
aperiodic measurement reporting has priority over semi-persistent measurement reporting, or semi-persistent measurement reporting has priority over periodic measurement reporting.

6. The apparatus according to claim 5 , wherein the reporting type involving a beam index indication is a reporting type involving a beam index indication and beam quality; and
the some of the plurality of measurement reporting parameters conform to the reporting type involving the beam index indication and beam quality.

7. The apparatus according to claim 6 , wherein the some of the plurality of measurement reporting parameters belong to a first measurement reporting setting, and among the plurality of measurement reporting parameters, a measurement reporting parameter other than the some of the plurality of measurement reporting parameters belongs to a second measurement reporting setting; and
the processor when the program is executed is further configured to perform operations of:
weighting and merging, the reporting rules to obtain a priority of the first measurement reporting setting and a priority of the second measurement reporting setting, wherein the first measurement reporting setting has priority over the second measurement reporting setting.

8. The apparatus according to claim 7 , wherein the processor when the program is executed is configured to perform an operation of:
determining that a reporting conflict has occurred, wherein the value or values of some of the plurality of measurement reporting parameters are sent after determining that a reporting conflict has occurred.

9. A measurement reporting method, comprising:
sending, by a base station, a pilot; and
receiving, by the base station, from a terminal, a value or values of some of a plurality of measurement reporting parameters that are associated with the pilot, wherein the some of the plurality of measurement reporting parameters conform to reporting rules, wherein the reporting rules comprise:
a reporting setting with a smaller identifier has priority over a reporting setting with a larger identifier;
a serving cell with a smaller identifier has priority over a serving cell with a larger identifier;
a reporting type involving a beam index indication has priority over a reporting type involving a rank indicator (RI); and
aperiodic measurement reporting has priority over semi-persistent measurement reporting, or semi-persistent measurement reporting has priority over periodic measurement reporting.

10. The method according to claim 9 , wherein the reporting type involving a beam index indication is a reporting type involving a beam index indication and beam quality; and
the some of the plurality of measurement reporting parameters conform to the reporting type involving a beam index indication and beam quality.

11. The method according to claim 10 , wherein the some of the plurality of measurement reporting parameters belong to a first measurement reporting setting, and among the plurality of measurement reporting parameters, a measurement reporting parameter other than the some of the plurality of measurement reporting parameters belongs to a second measurement reporting setting, wherein
the first measurement reporting setting has priority over the second measurement reporting setting, and a priority of the first measurement reporting setting and a priority of the second measurement reporting setting are obtained by weighting and merging the reporting rules.

12. The method according to claim 11 , further comprising:
sending, by the base station, the first measurement reporting setting and the second measurement reporting setting to the terminal.

13. The method according to claim 12 , further comprising:
sending, by the base station, a reporting activation indication associated with the plurality of measurement reporting parameters to the terminal.

14. A communications apparatus, comprising:
a processor;
a memory comprising a program to be executed in the processor, the processor when the program is executed is configured to perform operations of:
sending a pilot; and
receiving from a terminal, a value or values of some of a plurality of measurement reporting parameters that are associated with the pilot, wherein the some of the plurality of measurement reporting parameters conform to reporting rules, wherein the reporting rules comprise:
a reporting setting with a smaller identifier has priority over a reporting setting with a larger identifier;
a serving cell with a smaller identifier has priority over a serving cell wit
