PDCCH transmission method and system for bandwidth aggregation on a mobile communications system

摘要

The present invention relates to a PDCCH transmission method for a base station on a mobile communications system supporting bandwidth aggregation, and more particularly the invention relates to a PDCCH transmission method comprising the step of generating downlink control data comprising resource-allocation configuration data for any desired sub-band and a sub-band other than the desired sub-band, and the step of transmitting the generated downlink control data to a mobile station through the PDCCH of the desired sub-band, and the invention also relates to a system therefor comprising a mobile station.

1. A Physical Downlink Control Channel (PDCCH) transmission method of a base station in a mobile communication system supporting bandwidth aggregation, the method comprising:
generating downlink control information including resource allocation configuration information for a first band, a second band, and a guard band between the first band and the second band; and transmitting the downlink control information to a mobile terminal in a PDCCH of the first band, and wherein the resource allocation configuration information comprises a carrier index field indicating resource allocation in the first band, the second band and the guard band respectively.
