Method and apparatus for joint processing and precoding mode selection based on limited feedback in mobile communication system
According to one embodiment, a method of a base station configured to select a precoding mode in a mobile communication system. When channel estimate information is received from at least one terminal, the channel estimate information is collected, so that user grouping is performed according to one precoding scheme from among multiple precoding schemes. Individual user scheduling is performed according to each precoding scheme, so that a service candidate group set is generated. The selected precoding scheme is maximized according to a transmission capacity of a service candidate group set for each precoding scheme. Data is then transmitted to a determined candidate group set using the determined precoding scheme.
