US 2014/0112296 A1 · ADAPTIVE TRANSMISSION DEVICE USING LIMITED FEEDBACK INFORMATION IN A MOBILE COMMUNICATION SYSTEM, AND A METHOD THEREOF

Abstract

The present invention relates to an adaptive transmitting device using limited feedback information in a mobile communication system, and a method thereof. According to an exemplary embodiment of the present invention, when the base station transmits a pilot signal to the terminal, the terminal generates channel information by using the pilot signal, generates additional channel information from the channel information, and transmits the channel information and the additional channel information to the base station. The base station determines band allocation, power allocation, and modulation methods for each use by using received feedback information, and transmits modulated traffic data to the terminal according to the determined methods.

Claims4

Dependent claims

A method for a base station to receive information on a channel including N bands from a terminal, wherein N is a natural number, the method comprising:

receiving, from the terminal, channel quality information of m band(s) selected from the entire N bands, wherein m is a natural number and is less than N, channel location information of the selected m band(s), and one channel quality information that represents channel quality of the entire N bands;
allocating a band to the terminal by using the channel quality information of the selected m band(s), the channel location information of the selected m band(s), and the one channel quality information that represents channel quality of the entire N bands;
and
transmitting data to the terminal through the allocated band.
