Abstract

A method and device for reporting information based on carrier aggregation and a non-transitory computer-readable storage medium are provided. The method includes: determining a first maximum output power of each of carriers in a carrier aggregation scenario when being used as a single carrier; determining a second maximum output power, in the carrier aggregation scenario, of each of the carriers; and reporting, in response to detecting that there is a target carrier with the first maximum output power larger than the second maximum output power in the carrier aggregation scenario, a power class corresponding to the second maximum output power of the target carrier to a base station.

First claim

What is claimed is:

1. A method for reporting information based on carrier aggregation, comprising:
determining a first maximum output power supported by each of a plurality of carriers when being used as a single carrier;
determining a second maximum output power, in a carrier aggregation scenario, supported by each of the carriers; and
reporting, in response to detecting that there is a target carrier with the first maximum output power larger supported than the second maximum output power supported in the carrier aggregation scenario, a power class corresponding to the second maximum output power supported by the target carrier to a base station.

2. The method according to claim 1 , wherein reporting the power class corresponding to the second maximum output power supported by the target carrier to the base station comprises:
generating first indication information comprising a carrier identification field and a power class field, wherein the carrier identification field is configured to indicate at least an identification corresponding to the target carrier, and the power class field is configured to indicate at least the power class corresponding to the second maximum output power supported by the target carrier; and
transmitting the first indication information to the base station.

3. The method according to claim 2 , wherein the first indication information is transmitted to the base station, so that the base station updates, according to first indication information, a power class corresponding to the first maximum output power supported by the target carrier to the power class corresponding to the second maximum output power supported by the target carrier.

4. The method according to claim 2 , further comprising:
reporting, in response to detecting that there is no target carrier with the first maximum output power larger supported than the second maximum output power supported in the carrier aggregation scenario, second indication information comprising the carrier identification field; and
transmitting the second indication information to the base station, so that the base station determines, in response to detecting that there is a default field in the second indication information, that there is no power class update indication.

5. The method according to claim 1 , further comprising:
reassigning, in response to receiving a carrier assignment instruction, transmitting channels corresponding to the carriers, so that the transmitting channels correspond to the carriers in a one-to-one correspondence; and
performing carrier aggregation on the carriers and determining that the carriers are in the carrier aggregation scenario.

6. The method according to claim 1 , further comprising, after switching to the carrier aggregation scenario, uploading, in response to determining that there is uplink data, the uplink data to the base station at an output power less than or equal to the second maximum output power supported by the target carrier.

7. The method according to claim 1 , wherein the carriers are intra-band contiguous, intra-band non-contiguous or inter-band non-contiguous.

8. The method according to claim 1 , wherein reporting the power class corresponding to the second maximum output power supported by the target carrier to the base station comprises:
determining at least one cell to which a terminal device belongs, and determining a base station corresponding to each of the at least one cell; and
reporting the power class corresponding to the second maximum output power supported by the target carrier to the base station corresponding to each of the at least one cell.

9. The method according to claim 1 , further comprising transmitting, in response to detecting that there is no target carrier with the first maximum output power larger supported than the second maximum output power supported in the carrier aggregation scenario, third indication information to the base station, wherein the third indication information does not comprise a carrier identification field or a power class field.

10. The method according to claim 9 , wherein the third indication information is transmitted to the base station, so that the base station determines not to update the power classes corresponding to the carriers according to the third indication information.

11. The method according to claim 1 , wherein in the carrier aggregation scenario, each of the carriers corresponds to one transmitting channel, and in a single carrier scenario, each of the carriers corresponds to one or more transmitting channels.

12. The method according to claim 1 , wherein the base station is at least one of a 3G base station, a 4G base station, a 5G base station, and a 6G base station.

13. The method according to claim 1 , wherein a terminal device transmitting the carriers applies a time division duplex TDD mode.

14. The method according to claim 1 , wherein the carrier aggregation scenario comprises a carrier aggregation scenario in 4G and 5G dual connectivity.

15. A non-transitory computer-readable storage medium having computer programs stored thereon that, when being executed by at least one processor, causes the at least one processor to implement:
determining a first maximum output power supported by each of a plurality of carriers when being used as a single carrier;
determining a second maximum output power, in a carrier aggregation scenario, supported by each of the carriers; and
reporting, in response to detecting that there is a target carrier with the first maximum output power larger supported than the second maximum output power supported in the carrier aggregation scenario, a power class corresponding to the second maximum output power supported by the target carrier to a base station.

16. A device for reporting information based on carrier aggregation, comprising:
at least one hardware processor; and
a memory for storing program instructions that are executable by the at least one hardware processor, wherein the program instructions, when being executed by the at least one hardware processor, direct the at least one processor to implement:
determining a first maximum output power supported by each of a plurality of carriers when being used as a single carrier;
determining a second maximum output power, in a carrier aggregation scenario, supported by each of the carriers; and
reporting, in response to detecting that there is a target carrier with the first maximum output power larger supported than the second maximum output power supported in the carrier aggregation scenario, a power class corresponding to the second maximum output power supported by the target carrier to a base station.

17. The device according to claim 16 , wherein reporting the power class corresponding to the second maximum output power supported by the target carrier to the base station comprises:
generating first indication information comprising a carrier identification field and a power class field, wherein the carrier identification field is configured to indicate at least an identification corresponding to the target carrier, and the power class field is configured to indicate at least the power class corresponding to the second maximum output power supported by the target carrier; and
transmitting the first indication information to the base station.

18. The device according to claim 17 , wherein the first indication information is transmitted to the base station, so that the base station updates, according to first indication information, a power class corresponding to
