Abstract

A mobile communication system (100) which supports an LTE communication terminal (102) and an LTE-A communication terminal (103).  The frequency band width of the mobile communication system (100) is divided into a main frequency band and one or more sub frequency bands.  When a base station (101) receives operation width information showing an operable frequency band width of the communication terminal (102, 103) from the communication terminal (102, 103), the base station (101) sets the main frequency band and a sub frequency band selected by the base station (101) as the operation frequency band of the communication terminal to the communication terminal (102, 103), determines, out of the set operation frequency band, a sub frequency band to which PDCCH is assigned, and assigns the PDCCH of LTE to the determined sub frequency band.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a downlink implementation method of an LTE-Advanced system, a corresponding base station and user equipment. Background technique [0002] From April 7th to 8th, 2008, 3GPP held the IMT Advanced Workshop meeting in Shenzhen, China, where the requirements of Advanced LTE (LTE-Advanced) and possible related technical proposals were discussed. At the meeting, many companies raised the issue of the frequency band of the LTE-Advanced system and the issue of frequency spectrum aggregation. After discussion and deliberation, the chairman of the meeting submitted a draft LTE-Advanced requirements (REV-080058, Draft LTE-Advanced Requirements), which clearly pointed out that the LTE-Advanced system needs to support a maximum system frequency band of 100MHz. The 100 MHz system frequency band may be a continuous spectrum, or may be obtained by performing spectrum aggreg...
