METHOD AND DEVICE FOR SELECTING A PREPROCESSING MODE FOR CO-TREATMENT AND TRANSMISSION BASED ON RESTRICTIVE FEEDBACK IN A MOBILE COMMUNICATION SYSTEM CAPABLE OF INCREASING THE TRANSMISSION CAPACITY OF THE ENTIRE SYSTEM BY SELECTING AN EFFICIENT PREPROCESSING MODE
PURPOSE: A method and a device for selecting a preprocessing mode for co-treatment and transmission based on restrictive feedback in a mobile communication system are provided to efficiently service multiple users with regard to a temporally variable channel environment.;CONSTITUTION: When channel estimation information is received from at least one terminal, a base station groups users by a preprocessing mode(420,430). The base station generates a service candidate group by scheduling each user group(440). The base station determines a preprocessing mode for maximizing the transmission capacity of the service candidate group(450). The base station transmits data to the determined candidate group by using the determined preprocessing mode(460).;COPYRIGHT KIPO 2013;[Reference numerals] (410) Transmitting training sequence to a terminal; (420) Are CDI and CQI received from the terminal?; (430) Sharing information about the terminal to base stations and executing user grouping according to each preprocessing mode; (440) Generating a service candidate group by performing scheduling to each user group; (450) Determining one of the preprocessing modes for maximizing the transmission capacity of the service candidate group and sharing the information to adjacent cooperative base stations through backhaul; (460) Transmitting a symbol(data) to the determined service candidate group; (AA) Start; (BB) No; (CC) Yes; (DD) End
