Abstract: Embodiments provide a method for controlling an uplink transmit power in inter-base station carrier aggregation. The method includes acquiring, by a first base station, a maximum uplink transmit power that is allocated by user equipment (UE) to the first base station, and configuring, by the first base station, an uplink transmit power for the UE according to the maximum uplink transmit power. In the method, because the maximum transmit power allocated to the first base station is allocated according to status information of an uplink resource of a second base station, a power that is allocated by the UE to each base station can be coordinated.

Abstract: A method for processing data after an unlicensed spectrum is released, and user equipment are disclosed. The method includes: when user equipment determines that a base station has released an unlicensed spectrum, monitoring, by the user equipment, release time for which the unlicensed spectrum is released a release time for which the unlicensed spectrum is released; when the release time does not exceed a time threshold, pausing, by the user equipment, a data processing process attached to the unlicensed spectrum, and resuming the data processing process after the base station re-acquires the unlicensed spectrum; and when the release time exceeds the time threshold, terminating, by the user equipment, the data processing process attached to the unlicensed spectrum, and selecting a licensed spectrum to start a new data processing process, or after the base station re-acquires the unlicensed spectrum, starting a new data processing process.
