Abstract: PURPOSE: A mobile communication method in a multiple cellular environment and an apparatus thereof are provided to optimize the selection of a channel when a user performs feedback. CONSTITUTION: A channel selecting unit(130) selects a channel which feedbacks channel information based on feedback resource. An allocating unit(140) allocates an amount of feedback resources used in each terminal based on the size of the selected channels. A selection and allocation information transmitting unit(150) transmits information of the selected channel. A channel information receiving unit(160) feedbacks the channel information of the selected channel from each terminal. [Reference numerals] (110) Signal transmitting unit for estimating a channel; (120) Channel payment information reception unit; (130) Channel selecting unit; (140) Allocating unit; (150) Selection and allocation information transmitting unit; (160) Channel information receiving unit

Abstract: PURPOSE: A wireless communication system in a multi cell and a multi antenna environment and a method thereof are provided to actively estimate interference information from a terminal to an adjacent cell in multi cell environment, thereby using the interference information to an interference control. CONSTITUTION: A high frequency processor(140) changes a high frequency signal of a transmission method realization unit(130) to baseband signal. A information restoration unit(170) restores the baseband signal. A scheduler(105) assigns each time-frequency resources to terminals. A transmission power decision unit(120) determines a transmission power of a broadcasting signal based on load information of corresponding cell of a load information calculator(110). A interference information estimator(230) estimates the interference information based on a input signal of a high frequency processing unit(220).
