Patent ID: 8688135

Claim:
A method for implementing a carrier aggregation, comprising: determining predetermined information by a base station, wherein the predetermined information comprises reserved resources for the carrier aggregation and the capability of a user terminal; selecting a first carrier resource by the base station from the reserved resources according to the capability of the user terminal and selecting, for the user terminal, a second carrier resource for bearing data by the base station from the resources except the reserved resources; and aggregating the first and second carrier resources by the base station, wherein the step of aggregating the first and second carrier resources by the base station comprises: the base station receives a measurement result reported by the user terminal, wherein the measurement result is the result of a measurement of the user terminal on the interference of the first and second carrier resources selected by the base station; the base station determines, according to the measurement result, whether the interference of the user terminal meets the conditions for an inter-cell interference coordination in the system; and if the interference of the user terminal meets the conditions for an inter-cell interference coordination in the system, the base station aggregates the first and second carrier resources.
