Abstract

The disclosure discloses a method for reporting measurement capability, including: a UE reports the measurement capability of the UE to a base station, wherein the measurement capability is the capability of whether a measurement gap is required for the UE to execute different-frequency and different-system measurement when the UE operates in one frequency band or in a carrier aggregation scenario; and after acquiring the measurement capability of the UE, the base station determines whether to configure a measurement gap for the UE according to the frequency band to which carriers configured to be aggregated for the UE belong, the frequency band to which the carrier frequency for a measurement object of a currently configured measurement task belongs, and the measurement capability of the UE. The disclosure also discloses a UE correspondingly. By the disclosure, the base station is capable of not configuring a measurement gap for the UE if unnecessary, so that the influence of the different-frequency and different-system measurement to the service can be reduced, and possible resource waste caused can be avoided when the UE carries out measurement in the carrier aggregation scenario.

Claims

1. A method for reporting measurement capability, comprising:

reporting, by a UE, the measurement capability of the UE to a base station, wherein the measurement capability is the capability of whether a measurement gap is required for the UE to execute different-frequency and different-system measurement when the UE operates in one frequency band or in a carrier aggregation scenario.

3. The method according to claim 1, further comprising:

before the UE reports the measurement capability of the UE receiving, by the UE, a UE capability inquiry message from the base station.

4. The method according to claim 1, further comprising:

reporting, by the UE, a carrier aggregation capability of the UE while reporting the measurement capability of the UE to the base station.

6. The method according to claim 1, wherein when a maximum number of n carriers aggregation is supported, the carrier aggregation scenario comprises a scenario in which n carriers are aggregated.

7. The method according to claim 6, wherein when a maximum number of n carriers aggregation is supported, the carrier aggregation scenario further comprises a scenario in which one carrier, and/or two carriers, and/or three carriers . . . and/or n−

1 carriers are aggregated.

8. The method according to claim 6, wherein the UE measurement capability reported by the UE is the same as an index supporting the carrier aggregation capability.

21. The method according to claim 7, wherein the UE measurement capability reported by the UE is the same as an index supporting the carrier aggregation capability.

2. (canceled)

5. (canceled)

9. A UE, wherein the UE is configured to report a measurement capability of the UE to a base station, wherein the measurement capability is the capability of whether a measurement gap is required for the UE to execute different-frequency and different-system measurement when the UE operates in one frequency band or in a carrier aggregation scenario.

10. The UE according to claim 9, wherein the UE reporting the measurement capability of the UE to the base station is:

the UE reports according to a UE capability inquiry message sent by the base station.

11-12. -12. (canceled)

13. A method for reporting measurement capability, comprising:

receiving, by a base station, the measurement capability of a UE, wherein the measurement capability is the capability of whether a measurement gap is required for the UE to execute different-frequency and different-system measurement when the UE operates in one frequency band or in a carrier aggregation scenario.

14. The method according to claim 13, further comprising:

after the base station receives the measurement capability of the UE, determining, by the base station, whether to configure the measurement gap for the UE according to the frequency band to which carriers configured to be aggregated for the UE belong, the frequency band to which the carrier frequency for a measurement object of a currently configured measurement task belongs, and the measurement capability of the UE.

15. The method according to claim 13, further comprising:

before the base station receives the measurement capability of the UE, sending, by the base station, a UE capability inquiry message to the UE.

16. The method according to claim 13, wherein when a maximum number of n carriers aggregation is supported, the carrier aggregation scenario comprises a scenario in which n carriers are aggregated.

17. The method according to claim 16, wherein when a maximum number of n carriers aggregation is supported, the carrier aggregation scenario further comprises a scenario in which one carrier, and/or two carriers, and/or three carriers . . . and/or n−

1 carriers are aggregated.

18. The method according to claim 16, wherein the UE measurement capability received by the base station is the same as an index supporting the carrier aggregation capability.

22. The method according to claim 17, wherein the UE measurement capability received by the base station is the same as an index supporting the carrier aggregation capability.

19. A base station configured to receive a measurement capability of a UE, wherein the measurement capability is the capability of whether a measurement gap is required for the UE to execute different-frequency and different-system measurement when the UE operates in one frequency band or in a carrier aggregation scenario.

20. The base station according to claim 19, wherein the base station is configured to send a UE capability inquiry message to the UE before the base station receives the measurement capability of the UE.
