Title: UPLINK SCHEDULING METHOD AND DEVICE FOR CARRIER AGGREGATION
Abstract:
The present invention relates to the technical field of communications, and specifically relates to an uplink scheduling method and device for carrier aggregation. The method comprises: separately computing, for each component carrier after carrier aggregation, a transmission parameter of a UE unit to be scheduled, wherein the component carriers comprise PCells and SCells of the UE unit to be scheduled; determining, on the basis of the transmission parameter for each component carrier of the UE unit to be scheduled and according to a preset determination rule, a component carrier for uplink scheduling from the PCells and SCells of the UE unit to be scheduled; and allocating, on the basis of the component carrier for uplink scheduling, resources. In this way, the present invention enables flexible selection of a carrier involved in uplink scheduling for carrier aggregation from component carriers of a UE unit to be scheduled, thus preventing performance from being influenced by power reduction of the UE unit, maximizing the advantageous effects of carrier aggregation, and improving the throughput of the UE unit.
