METHOD AND APPARATUS FOR ESTIMATING CHANNEL QUALITY INFORMATION, BASE STATION AND NETWORK CENTRAL PROCESSING DEVICE |
摘要 |
The present invention provides a method and apparatus for estimating channel quality information, a base station and a network central processing device. According to the embodiments of the present invention, a macro cell includes multiple transmission points, the method can comprise receiving the channel quality information which is measured by a user equipment based on a cell specific reference signal; obtaining channel matrix information the multiple transmission points; calculating beamforming information on a single cell transmission and a coordinated multi-point transmission based on the channel matrix information; and estimating the channel quality information for the single cell transmission and the coordinated multi-point transmission based on the channel quality information, the channel matrix information, and the beamforming information. With embodiments of the present invention, it is possible to provide coordinated multi-point gains with no overhead introduced and it is compatible with the existing available user equipments. |
